Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
in order to avoid or reduce the influence of color difference generated on the screen of the electronic device on the visual experience as much as possible, in the screen display control method provided by this embodiment, when the screen of the electronic device is used for displaying, a calibration parameter of a screen to be calibrated of the electronic device is obtained, where the calibration parameter is obtained based on the color difference between the screen to be calibrated and a preset standard screen; and then generating a compensation layer of the screen to be calibrated according to the acquired calibration parameters, and displaying the obtained compensation layer and other layers of the screen to be calibrated in an overlapping manner, so that the color display effect of the screen to be calibrated of the electronic equipment is basically consistent with that of a preset standard screen, and the influence on visual experience when the screen of the electronic equipment generates color difference is avoided.
In an example of the embodiment, the color difference of the screen to be calibrated may be a color difference generated by comparing the screen to be calibrated with a preset standard screen. For ease of understanding, the present embodiment is described below in conjunction with an exemplary screen display control method, which is illustrated with reference to fig. 1 and includes:
s101: and acquiring calibration parameters of a screen to be calibrated of the electronic equipment.
S102: and generating a compensation layer of the screen to be calibrated according to the acquired calibration parameters.
S103: and overlapping and displaying the generated compensation layer and other layers of the screen to be calibrated.
The calibration parameters in S101 are obtained based on a color difference between a screen to be calibrated of the electronic device and a preset standard screen. And it should be understood that the calibration parameters for acquiring the screen to be calibrated in S101 include, but are not limited to, one of the following ways:
the first method is as follows: in an example, the calibration parameter may be pre-saved, and the obtaining in S101 may be obtaining the pre-saved calibration parameter;
the second method comprises the following steps: in another example, the calibration parameter may also be obtained in real time, and in this case, the obtaining in S101 may obtain the calibration parameter in real time according to a color difference between a screen to be calibrated of the electronic device and a preset standard screen.
In this embodiment, which acquisition method is specifically adopted to acquire the calibration parameter may be flexibly selected and determined according to a specific application scenario.
In addition, in this embodiment, the electronic device may be a single-screen device provided with only one screen (i.e., one display screen), or may be a multi-screen device provided with more than two screens (e.g., two display screens, or three display screens, etc.).
In an example of this embodiment, when the electronic device is a single-screen device, for example, the electronic device includes only the first screen, and the preset standard screen in this embodiment may be a screen of another device besides the electronic device. In this example, during the generation process of the screen device, the first screen of the single-screen electronic device may be displayed and compared with the preset standard screen to obtain a color difference therebetween, so as to obtain the calibration parameter, and/or during the delivery use process of the single-screen electronic device (for example, after using the preset time length or when detecting that the screen aging condition satisfies the preset condition, etc.), the current first screen may be displayed and compared with the preset standard screen to obtain the color difference therebetween, so as to obtain the calibration parameter. In this example, the preset standard screen may be a screen satisfying a preset standard display condition, and the preset annotation display condition may be flexibly set according to the application scene requirement.
In another example of this embodiment, when the electronic device is a multi-screen device, the preset standard screen may be a screen of another device other than the electronic device, or may be one of the screens of the electronic device. For example, when the electronic device is a dual-screen device including a first screen and a second screen, in an application scenario, the first screen may be set as a preset standard screen, the second screen is a screen to be calibrated, or the second screen is set as a preset standard screen, and the first screen is a screen to be calibrated, and at this time, only a corresponding compensation layer needs to be generated for the first screen or the second screen of the dual-screen device to perform overlay display; in another application scenario, the first screen and the second screen of the electronic device may be both screens to be calibrated, the preset standard screen may be a screen of another device other than the electronic device, the preset standard screen in the application scenario may be a screen meeting a preset standard display condition, and the preset annotation display condition may be flexibly set according to the application scenario requirements; at the moment, corresponding compensation layers are respectively generated for a first screen and a second screen of the double-sided screen device to be superposed and displayed; certainly, if there is no color difference between a certain screen and the preset standard screen, a compensation layer may be selectively not generated or a fully transparent blank compensation layer may be generated for the screen.
It should be understood that, for an electronic device including three or more screens, the manner of setting the screen to be calibrated and the preset standard screen may also be the manner exemplified above, and will not be described herein again.
In an example of this embodiment, a process of obtaining calibration parameters according to a color difference between a screen to be calibrated and a preset standard screen is shown in fig. 2, and includes:
s201: and determining a to-be-compensated area which needs to be subjected to chromatic aberration compensation on the to-be-calibrated screen according to the display difference between the to-be-calibrated screen and a preset standard screen.
In this embodiment, the determined area to be compensated, which needs to be subjected to color difference compensation, may be one area, or may be more than two areas, and when the area is one area, the area may cover the whole screen, or may be one partial area in the screen. Of course, in some cases, the determined number of the regions to be compensated may also be 0.
It should be understood that, in this embodiment, the determination and selection of the area to be compensated may be performed manually, for example, by an operator comparing and analyzing an area where the display difference exists between the screen to be calibrated and the preset standard screen, and dividing the partial area on the screen to be calibrated as the area to be compensated. In this embodiment, the determination and selection of the region to be compensated may also be implemented by automatic calculation and analysis through a preset algorithm.
S202: and acquiring a region determining parameter of the region to be compensated and a color difference value of the region to be compensated and a corresponding region on a preset standard screen.
For example, assuming that in an example, for one screen to be calibrated, two areas to be compensated are determined to exist on the screen, which are referred to as a first area to be compensated and a second area to be compensated in this example, a first area determining parameter of the first area to be compensated and a second area determining parameter of the second area to be compensated are obtained respectively, and a first color difference value of the first area to be compensated and a second color difference value of the second area to be compensated are obtained respectively. In this example, the acquisition process of the region determination parameter and the color difference value is not strictly time-sequence limited, and the region determination parameter and the color difference value may be acquired at the same time or at different times.
In addition, it should be understood that, in this embodiment, a specific calculation manner of the color difference value of the corresponding region on the screen to be calibrated and the preset standard screen may be flexibly determined according to an application scenario. The color value refers to a color value corresponding to one color in different color modes. And the color mode includes, but is not limited to, an RGB mode (where R stands for red, G stands for green, and B stands for blue), a print color mode (CMYK mode where C stands for cyan, M stands for magenta, Y stands for yellow, and K stands for black), an HSB (Hue-qualification-Brightness) mode or an LAB mode (where L stands for luminance, and a stands for color from dark green (base luminance value) to gray (middle luminance value) to bright pink red (high luminance value), and B stands for color from bright blue (base luminance value) to gray (middle luminance value) to yellow (high luminance value), the gamut of the LAB mode is widest, which includes all colors in the RGB gamut and the CMYK gamut, and does not cause loss in any color when converted using the LAB mode; wherein a color difference (Chromatic Aberration, CA) is expressed as a difference in color values of two colors in one color mode, it is expressed in NBS (National Bureau of Standard, the National institute of standards), mathematically by the distance between two color points in color space.
In this embodiment, the screen to be calibrated and the standard screen may display the same color map in the same mode, and for an area (that is, an area to be calibrated) in the screen to be calibrated, where there is a color difference with the area corresponding to the standard screen, the color currently displayed by the screen to be calibrated may be recorded as an initial color, and then the color of the area in the screen to be calibrated is changed until the display effect of the area in the screen to be calibrated is not or substantially not different from the display effect of the area in the standard screen, and the color of the area in the screen to be calibrated at this time is taken as a target color; and then calculating the difference value between the target color and the initial color to obtain a color difference, wherein the color difference can be used as the color difference value of the corresponding area of the screen to be calibrated and the standard screen. It should be understood that the dividing manner of the region to be calibrated in this embodiment may be flexibly set according to a specific application scenario.
S203: and storing the area determination parameters of the area to be compensated and the color difference values in a correlation manner.
For example, the first area determination parameter of the first area to be compensated and the first color difference value are stored in association, and the second area determination parameter of the second area to be compensated and the second color difference value are stored in association. It should be understood that, when the number of the to-be-compensated regions is greater than 2 or 1, the association storage manner of the region determination parameter and the color difference value of the to-be-compensated region is analogically performed, and details are not described herein.
In an example of this embodiment, referring to fig. 3, a process of generating a compensation layer of a screen to be calibrated according to calibration parameters of the screen to be calibrated includes:
s301: and generating a blank layer matched with the screen to be calibrated.
S302: and determining parameters and color difference values according to the areas which are stored in association with the calibration parameters, determining the areas to be rendered on the blank layer, rendering the corresponding areas to be rendered according to the corresponding color difference values, and setting the layer to be transparent to obtain a compensation layer.
For example, the above-described example in which the screen to be calibrated has the first area to be compensated and the second area to be compensated is also exemplified. In this example, a first region to be rendered and a second region to be rendered on the layer may be determined according to the first region determination parameter and the second region determination parameter, and then the first region to be rendered and the second region to be rendered are rendered according to the corresponding first color difference value and second color difference value, that is, the display colors of the first region to be rendered and the second region to be rendered are set according to the first color difference value and the second color difference value. It should be understood that when the number of the regions to be compensated is greater than 2 or 1, the rendering process for the blank layer is analogized, and details are not described herein.
In addition, it should be understood that, in this embodiment, the step of setting the layer to be transparent (that is, setting the alpha value of the layer to be 0 (full transparency)) and the step of rendering the layer may be performed simultaneously or not, and when not performed simultaneously, the execution sequence between the two steps may be flexibly set, for example, the layer may be set to be transparent first and then rendered according to the above process, or the layer may be rendered according to the above process first and then set to be transparent.
In an example of this embodiment, displaying the compensation layer of the screen to be calibrated in an overlapping manner with other layers of the screen to be calibrated may include:
the compensation layer of the screen to be calibrated is arranged on other layers of the screen to be calibrated for superposition display, namely the compensation layer is arranged on the top of all the layers of the screen to be calibrated, so that the color display effect of the screen to be calibrated of the electronic equipment is basically consistent with the color display effect of a preset standard screen, and the influence on visual experience when the screen of the electronic equipment generates color difference is avoided or reduced as much as possible.
Example two:
for convenience of understanding, in the following description of the present embodiment, the electronic device is an electronic device having more than two display screens (i.e., screens), and includes various dual-screen electronic devices, and even electronic devices having three or more screens. The following description of the present embodiment is made by taking a dual-panel electronic device as an example.
The dual-screen electronic device in this embodiment may be a dual-screen intelligent electronic device in various forms. For example, referring to a double-sided screen electronic device shown in fig. 4-1 to 4-3, in the state shown in fig. 4-1, two display screens of the double-sided screen electronic device 4 are in a folded state, and a first screen 41 located on the front side of the electronic device faces a user. In the state shown in fig. 4-2, the two display screens of the dual-screen electronic device 1 are in the state during the opening process, the first screen 11 and the second screen 12 can rotate relatively to realize the unfolding, and the final example unfolding state can be shown in fig. 4-3, where the first screen 11 and the second screen 12 are in the same plane or substantially in the same plane.
For another example, referring to fig. 5-1 to 5-2, a dual-screen electronic device 5 is shown, the dual-screen electronic device 5 having a first screen 51 on the front side of the electronic device and a second screen 52 on the back side of the electronic device, the positions of the two screens being fixed. The first screen 51 and the second screen 52 may have the same size or different sizes, and may be flexibly set according to the requirements. For example, in one example, the second screen 52 may be set to be smaller in size than the first screen 51.
It should be understood that the dual-screen electronic device in the present embodiment is not limited to the above-described exemplary structure, for example, in some examples, the first screen and the second screen are both located on the front side of the electronic device at the same time, and the like.
For convenience of understanding, the present embodiment is exemplified by the application of the dual-screen electronic device shown in fig. 4-1 to 4-3, but it should be understood that the display control process for other forms of multi-screen electronic devices is similar and will not be described herein again.
In some application scenarios, the dual-screen electronic device shown in fig. 4-1 to 4-3 includes, but is not limited to, at least one of the following four modes of display:
large A mode: the two screens are used as one screen to display the same application, each screen displays a part of one application, and optionally, the left half part and the right half part or the upper half part and the lower half part of the application can be respectively displayed according to the change conditions of the horizontal screen and the vertical screen.
AB mode: the two screens each display a different application, in which case the two screens are similar to the display screens of the two devices, and there may be substantially no continuity or correlation between the two.
AA mode (i.e., mirror mode): both screens display the same application at the same time, but each screen will display all parts of the application in full, except that they are displayed in an axisymmetric fashion.
AX mode: currently, only one display screen is available for opening, for example, the first screen is opened, and the second screen is closed; or the first screen is off and the second screen is on).
In the above modes, the AA mode, the AB mode, and the large a mode are all implemented on the premise that two display screens of the device are currently required to be in an on state, and if there is a color difference between the two current screens, the phenomenon is easily found, and particularly in the large a mode or the AA mode, the phenomenon is more obvious, which results in poor satisfaction of user experience. The method for controlling screen display provided by this embodiment may be applicable to the above four modes, or may only be specific to a part of the four modes, for example, when it is determined that the device is in an AA mode, an AB mode, or a large a mode, or in an AA mode or a large a mode, the method for controlling screen display provided by this embodiment is enabled to perform display control on the first screen and/or the second screen. In this embodiment, a first screen of a dual-screen electronic device is used as a screen to be calibrated, and a second screen is used as a preset standard screen (of course, in some application scenarios, the second screen of the dual-screen electronic device may also be used as the screen to be calibrated, and the first screen is used as the preset standard screen, or the first screen and the second screen of the dual-screen electronic device are both directly used as the screen to be calibrated, and screens of other devices are used as the preset standard screens). In this embodiment, the color difference value between each region of the two screens is obtained through calibration calculation, after the color difference value of each region exists, a compensation layer may be added to a display layer of the first screen of the electronic device, the compensation layer may set a color value and an alpha value according to the color difference value of each region, the color value and the alpha value are the color difference value of the corresponding region of the two screens obtained through calculation, and only one compensation layer needs to be added to the screen to be calibrated (i.e., the first screen), so that the first screen and the second screen which are finally seen by the user are substantially color-difference-free, and the visual effect is improved. This control scheme may also be employed for devices having more than two screens, such that the multiple screens are substantially color-free.
In one example, the control process may include a calibration parameter acquisition process, and a compensation process in the display process.
In one example, the calibration parameter acquisition process may include: the method comprises the steps that a first screen and a second screen enter a calibration contrast interface, for example, the two screens display white, the first screen is determined to be a screen to be calibrated, the second screen is a preset standard screen, and a region of the first screen, which needs to be calibrated relative to the second screen, is determined, namely the region to be calibrated, and the region to be calibrated can include but is not limited to a region displaying red or green; then, through linearly displaying red and green to a screen to be calibrated, preliminarily selecting and confirming proper color difference values for each area to be calibrated, and storing the color difference values of the areas as parameters for color filling in subsequent display compensation; and the area parameters of each area to be calibrated and the color difference value of each cross calibration area can be stored in a correlated manner.
In one example, the compensation process in the display process may include: when the electronic device enters a normal startup display process, when the system framework is started completely and before the electronic device does not enter an application interface, a calibration parameter obtained in a calibration parameter obtaining process can be read in a window management system (certainly, the calibration parameter can be obtained in real time according to the parameter obtaining process at this time), a compensation layer is added to a screen to be calibrated according to the calibration parameter, specifically, the compensation layer can be set to be positioned at the uppermost part of each coating of the screen to be calibrated, color difference (namely, compensation color) of a corresponding area can be set to be used as display color of the corresponding area in the compensation layer, and an alpha value of the compensation layer can be set to be fully transparent.
By the method provided by the embodiment, the chromatic aberration of the double screens can be compensated in a mode of adding the compensation layer to compensate the chromatic aberration, so that the visual effect of displaying no chromatic aberration in the double screens is achieved. The following description is given by taking an example of a calibration parameter obtaining process, and please refer to fig. 6, which includes:
s601: the double-screen electronic equipment enters a calibration interface, and white can be displayed on the first screen and the second screen at the same time.
S602: determining whether calibration is needed, if yes, going to S603; otherwise, go to S608.
In an example, whether calibration is needed or not can be judged according to the display conditions of the two screens through an operator or a preset algorithm, if no color difference exists, the step S608 is not needed, and if the color difference exists, the step S603 is needed, for example, a corresponding control icon on a screen to be calibrated (i.e., a first screen) is selected, and the current screen is triggered to be used as the screen to be calibrated to enter a calibration process.
S603: and determining areas with color difference with the standard screen on the screen to be calibrated, and selecting one or more color difference areas as the areas to be calibrated.
For example, an exemplary selected region to be calibrated is shown in fig. 7, and two regions marked by C1 and C2 in fig. 7 are regions to be calibrated, and region determination parameters for determining C1 and C2 can be obtained.
S604: and displaying the color spectrum on the selected area to be calibrated in a way of linearly decreasing the components of the color RGB.
In this example, the areas to be calibrated, which are circled in fig. 7, may be sequentially taken out as the areas to be currently calibrated to enter S604, and if all the selected areas are calibrated, the calibration is completed.
S605: and comparing the other preset standard screen according to the display of the regional color spectrum to be calibrated, selecting a color consistent with the color, and performing preview comparison until the preview display colors of the two screens are consistent finally.
S606: and according to the color selected in the last step (namely the target color), calculating the color difference value between the current screen color to be calibrated (namely the initial color) and the target color selected in the last step.
S607: the area determination parameters and the color difference values of the areas to be calibrated (such as the areas C1 and C2) are written into a file to be saved.
S608: and if the first screen and the second screen have no color difference, a calibration process can be deduced, or a file with the color difference value of 0 is generated for storage.
The following description is made in conjunction with an exemplary compensation process in the display process, and please refer to fig. 8, which includes:
s801: the electronic equipment is started, and a window, a screen and the like enter a ready application window interface to be started.
S802: reading the calibration information file written in the calibration parameter acquisition process, and judging whether the reading is successful, if so, turning to S803; otherwise, go to S806.
Of course, the calibration parameters may be obtained in real time in the present step in the manner shown in fig. 6.
S803: and analyzing the content of the calibration information file to obtain corresponding area determination parameters and color difference values.
Alternatively, in this example, when the read color difference value is 0, the process may also directly go to S806.
S804: a compensation layer is generated, and the compensation layer is rendered by using the region-determining parameter and the color difference value obtained in step S803, for example, it is assumed that a rendering region of the compensation layer is shown in fig. 9.
S805: and adding the compensation layer generated in the step S804 to the screen to be calibrated, and displaying the compensation layer on the top of all layers of the screen to be calibrated all the time. For example, an overlay display diagram can be seen in fig. 10, where 1001, 1002, and 1003 are a Wallpaper layer (Wallpaper), an application layer (APP), and a status bar layer (statubar), respectively, and 1004 is a compensation layer 1004, and the compensation layer 1004 is always located above the Wallpaper layer 1001, the application layer 1002, and the status bar layer 1003. Of course, if the screen of the other device than the dual-screen electronic device is used as the standard screen, in an example, the compensation layer 1004 may be generated in both the first screen and the second screen for the overlay display.
S806: and entering a normal application starting process.
Therefore, by the display control method provided by the embodiment, the colors of the two screens of the dual-screen electronic device can be displayed basically without color difference, so that the consistency of screen display of the dual-screen electronic device and the satisfaction degree of user experience can be improved.

In an example of this embodiment, when the electronic device is a single-screen device, for example, the electronic device includes only the first screen, and the preset standard screen in this embodiment may be a screen of another device besides the electronic device. In this example, during the generation process of the screen device, the first screen of the single-screen electronic device may be displayed and compared with the preset standard screen to obtain a color difference therebetween, so as to obtain the calibration parameter, and/or during the delivery use process of the single-screen electronic device (for example, after using the preset time length or when detecting that the screen aging condition satisfies the preset condition, etc.), the current first screen may be displayed and compared with the preset standard screen to obtain the color difference therebetween, so as to obtain the calibration parameter. In this example, the preset standard screen may be a screen satisfying a preset standard display condition, and the preset annotation display condition may be flexibly set according to the application scene requirement.
In another example of this embodiment, when the electronic device is a multi-screen device, the preset standard screen may be a screen of another device other than the electronic device, or may be one of the screens of the electronic device. For example, when the electronic device is a dual-screen device including a first screen and a second screen, in an application scenario, the first screen may be set as a preset standard screen, the second screen is a screen to be calibrated, or the second screen is set as a preset standard screen, and the first screen is a screen to be calibrated, and at this time, only a corresponding compensation layer needs to be generated for the first screen or the second screen of the dual-screen device to perform overlay display; in another application scenario, the first screen and the second screen of the electronic device may be both screens to be calibrated, the preset standard screen may be a screen of another device other than the electronic device, the preset standard screen in the application scenario may be a screen meeting a preset standard display condition, and the preset annotation display condition may be flexibly set according to the application scenario requirements; at the moment, corresponding compensation layers are respectively generated for a first screen and a second screen of the double-sided screen device to be superposed and displayed; certainly, if there is no color difference between a certain screen and the preset standard screen, a compensation layer may be selectively not generated or a fully transparent blank compensation layer may be generated for the screen.
It should be understood that, for an electronic device including three or more screens, the manner of setting the screen to be calibrated and the preset standard screen may also be the manner exemplified above, and will not be described herein again.
In an example of the embodiment, the process of the parameter obtaining module 1101 obtaining the calibration parameter according to the color difference between the screen to be calibrated and the preset standard screen may include: the parameter obtaining module 1101 determines a to-be-compensated area, which needs to be subjected to color difference compensation, on the to-be-calibrated screen according to a display difference between the to-be-calibrated screen and the preset standard screen, obtains an area determining parameter of the to-be-compensated area and a color difference value of the to-be-compensated area and a corresponding area on the preset standard screen, and stores the area determining parameter and the color difference value of the to-be-compensated area in a correlated manner.
In this embodiment, the determined area to be compensated, which needs to be subjected to color difference compensation, may be one area, or may be more than two areas, and when the area is one area, the area may cover the whole screen, or may be one partial area in the screen. Of course, in some cases, the determined number of the regions to be compensated may also be 0.
It should be understood that, in this embodiment, the determination and selection of the area to be compensated may be performed manually, for example, by an operator comparing and analyzing an area where the display difference exists between the screen to be calibrated and the preset standard screen, and dividing the partial area on the screen to be calibrated as the area to be compensated. In this embodiment, the determination and selection of the region to be compensated may also be implemented by automatic calculation and analysis through a preset algorithm.
For example, assuming that in an example, for one screen to be calibrated, two areas to be compensated are determined to exist on the screen, which are referred to as a first area to be compensated and a second area to be compensated in this example, a first area determining parameter of the first area to be compensated and a second area determining parameter of the second area to be compensated are obtained respectively, and a first color difference value of the first area to be compensated and a second color difference value of the second area to be compensated are obtained respectively. In this example, the acquisition process of the region determination parameter and the color difference value is not strictly time-sequence limited, and the region determination parameter and the color difference value may be acquired at the same time or at different times.
For example, the first area determination parameter of the first area to be compensated and the first color difference value are stored in association, and the second area determination parameter of the second area to be compensated and the second color difference value are stored in association. It should be understood that, when the number of the to-be-compensated regions is greater than 2 or 1, the association storage manner of the region determination parameter and the color difference value of the to-be-compensated region is analogically performed, and details are not described herein.
In an example of this embodiment, the process of generating, by the display control module 1103, the compensation layer of the screen to be calibrated according to the calibration parameter of the screen to be calibrated includes: the display control module 1103 generates a blank layer matched with the screen to be calibrated, determines parameters and color difference values according to the areas stored in association with the calibration parameters, determines an area to be rendered on the blank layer, renders the corresponding area to be rendered according to the corresponding color difference values, and sets the layer to be transparent to obtain a compensation layer.
For example, the above-described example in which the screen to be calibrated has the first area to be compensated and the second area to be compensated is also exemplified. In this example, a first region to be rendered and a second region to be rendered on the layer may be determined according to the first region determination parameter and the second region determination parameter, and then the first region to be rendered and the second region to be rendered are rendered according to the corresponding first color difference value and second color difference value, that is, the display colors of the first region to be rendered and the second region to be rendered are set according to the first color difference value and the second color difference value. It should be understood that when the number of the regions to be compensated is greater than 2 or 1, the rendering process for the blank layer is analogized, and details are not described herein.
In addition, it should be understood that, in this embodiment, the step of setting the layer to be transparent (that is, setting the alpha value of the layer to be 0 (full transparency)) and the step of rendering the layer may be performed simultaneously or not, and when not performed simultaneously, the execution sequence between the two steps may be flexibly set, for example, the layer may be set to be transparent first and then rendered according to the above process, or the layer may be rendered according to the above process first and then set to be transparent.
In an example of this embodiment, the displaying, by the display control module 1103, the overlapping and displaying the compensation layer of the screen to be calibrated and the other layers of the screen to be calibrated may include: the display control module 1103 sets the compensation layer of the screen to be calibrated on other layers of the screen to be calibrated for superposition display, that is, sets the compensation layer on the top of all layers of the screen to be calibrated, so that the color display effect of the screen to be calibrated of the electronic device is substantially consistent with the color display effect of the preset standard screen, and the influence on visual experience when the screen of the electronic device generates color difference is avoided or reduced as much as possible.
It should be understood that the functions of the parameter obtaining module 1101, the layer generating module 1102 and the display control module 1103 described above may be implemented by a processor or a controller of an electronic device. Moreover, by the screen display control device provided by the embodiment, the display effect of the screen to be calibrated of the electronic device is basically consistent with the display effect of the preset standard screen, so that the influence on the visual experience when the screen to be calibrated of the electronic device generates color difference is avoided, and the satisfaction degree of the user experience is improved.
