Referring to fig. 1, fig. 1 is a schematic diagram of a first structure of a display device 100 according to an embodiment of the application.
The display device 100 includes a display area and a non-display area 130, wherein the non-display area 130 may be a transparent area, and the non-display area 130 may be used to transmit external light irradiated from the outside of the display device 100 into the inside of the display device 100. The material of the non-display area 130 may be glass, plastic, or a composite glass-plastic material.
The display area includes a first display area 110 and a second display area 120, and the first display area 110 and the second display area 120 may be disposed at opposite sides of the display device 100 with a non-display area 130 interposed therebetween in the first display area 110 and the second display area 120.
The material of the display area may be an OLED (Organic Light-Emitting Diode) display panel, or may be a display panel made of an inorganic Light-Emitting Diode material. The display area is also transparent without any current drive, e.g. the display area may be made of a transparent material, such as an indium tin oxide transparent film material.
The display area includes a plurality of pixels, and the pixels can be in different working states, for example, when the pixels are in a first working state, the pixels can generate corresponding colors, such as blue, black and the like. When the pixel is in the second working state, the area corresponding to the pixel can be the area without the on current, and the area where the pixel is located is transparent.
In some embodiments, the display device 100 further includes a controller, which may be a processor. The controller may be disposed outside the display area and the non-display area 130 of the display device 100, and the controller may be connected to a control unit for controlling pixels in the display area through a transparent flat cable, for example, the controller may be connected to a gate, a drain, and a source in the display area through the transparent flat cable.
The controller may be used to control the operation states of the plurality of pixels in the display area according to the external light to control the transmittance of the external light from the outside of the display device 100 to the inside of the display device 100.
For example, the controller may control the operation state of the plurality of pixels in the display area according to the angle and intensity of the external light irradiated into the display area.
Referring to fig. 2 together, fig. 2 is a schematic diagram of a second structure of the display device 100 according to the embodiment of the application.
Wherein the display device 100 further comprises an angle sensor 160 and a light sensor. The light sensor may be disposed within a predetermined distance of the display area, such as a distance of only a few centimeters from the display area. The light sensor may be used to sense the intensity and angle of light from outside light impinging on the display device 100.
In some embodiments, a corresponding light sensor may be disposed in each of the different display areas, so that the light intensity and the light angle corresponding to the external light irradiated on each of the different display areas can be determined more accurately.
As shown in fig. 2, the first display area 110 is provided with a corresponding first light sensor 140, and the second display area 120 is provided with a corresponding second light sensor 150. The first light sensor 140 is used for sensing the light intensity and the light angle of the external light irradiated on the first display area 110, and the second light sensor 150 is used for sensing the light intensity and the light angle of the external light irradiated on the second display area 120.
In some embodiments, the electronic device may determine the first target pixel on the first display area 110 according to the light intensity and the light angle acquired by the first light sensor 140, and then control the target pixel to enter the first working state, so that the first target pixel changes color, for example, changes to black, so as to reduce the transmittance of the external light from the outside of the display device 100 to the inside of the display device 100.
The electronic device may further determine a second target pixel on the second display area 120 according to the light intensity and the light angle obtained by the second light sensor 150, and then control the target pixel to enter the first working state, so that the second target pixel changes color, for example, changes to black, thereby reducing the transmittance of the external light from the outside of the display device 100 to the inside of the display device 100.
In some embodiments, as shown in fig. 2, an angle sensor 160 may be disposed near the display area, such as the angle sensor 160 disposed near the first display area 110. The angle sensor 160 may be disposed within a predetermined distance of the first display area 110, and the angle sensor 160 may be a camera, a laser sensor, or the like. An angle sensor 160 may also be disposed near the second display area 120.
If the human eye needs to look from the inside of the display device 100 to the outside of the display device 100, the angle sensor 160 is required to acquire the target angle between the human eye and the inside of the display area, then the target angle is also used as a control factor, the controller determines the target pixel in the display area according to the target angle, the light intensity and the light angle, and finally the target pixel is controlled to enter the first working state, so that the corresponding color is generated.
In this way, the transmittance of the external light passing through the display device 100 can be controlled, so that it is ensured that enough external light irradiates into the human eyes, so that the human eyes can see the scenery outside the display device 100, and meanwhile, since the target pixel generates a color, a certain shielding effect can be performed on the external light, so that excessive light passing through the inner side of the display device 100 is prevented, and the human eyes are stimulated.
It should be noted that, in the embodiment of the present application, the number of display areas may be set according to actual needs, for example, the display device 100 includes only one display area, and the other areas are non-display areas 130. Or the display device 100 is provided with only the display area and the non-display area 130 is not provided.
For a more detailed understanding of the display device 100 provided in the embodiment of the application, please refer to fig. 3, fig. 3 is a schematic diagram of a first operation scenario of the display device 100 provided in the embodiment of the application.
Taking the first display area 110 as an example, after the external light irradiates the first display area 110, the first light sensor 140 may capture the light intensity and the light angle of the external light, then transmit the light intensity and the light angle to the controller, and when the controller determines that the light intensity is greater than the preset light intensity threshold, the controller may determine the target pixel in the first display area 110 according to the light intensity and the light angle, and then control the target pixel to enter the first working state, so as to enable the target pixel to generate a color.
As shown in fig. 3, the first display area 110 includes a first color-changing area 112 and a non-color-changing area 111, where a pixel corresponding to the first color-changing area 112 is a target pixel, and the transmittance of external light transmitted through the first color-changing area 112 can be reduced when the target pixel generates a color in the first color-changing area 112. The non-color-changing area 111 has no color, the non-color-changing area 111 can directly transmit external light, and the pixels of the non-color-changing area 111 are in the second working state.
Referring to fig. 4, fig. 4 is a schematic diagram of a second operation scenario of the display device 100 according to the embodiment of the application.
On the left side of the center axis PP is the outside of the display device 100, and on the right side of the center axis PP is the inside of the display device 100. When the external light irradiates from the outside to the inside, the controller controls the target pixel of the first display area 110 to enter the first working state, and the target pixel generates color, thereby forming the first color-changing area 112. When part of the external light irradiates the first color-changing area 112, the first color-changing area 112 has a certain shielding effect on the external light, so that the transmittance of the external light is changed.
While other external light may be transmitted through the non-color-changing regions 111 to enter the human eye, and the human eye may view the environment outside the display device 100 through the light transmitted through the non-color-changing regions 111.
Referring to fig. 5, fig. 5 is a schematic diagram of a third operation scenario of the display device 100 according to the embodiment of the application.
In the first display area 110, the determination of the target pixel is related to the light angle, and when the light angle changes from the light angle in fig. 3, the controller redetermines the target pixel according to the light angle and the light intensity, so as to form a first color-changing area 112 and a non-color-changing area 111 as shown in fig. 5.
Since the first color-changing region 112 and the non-color-changing region 111 are changed, a louver-like effect is formed, so that the first color-changing region 112 shields external light from another angle. So that the light entering the human eyes is soft and prevents the human eyes from being stimulated.
When the display device 100 is applied to a windshield of an automobile, shielding of sunlight can be achieved, and eyes of a driver are prevented from receiving external stimulus, so that driving safety of the driver is guaranteed.
When the display device 100 is applied to a window, the distribution of the color-changing region and the non-color-changing region 111 of the display region of the display device 100 can be changed according to the change of the solar rays. Therefore, when the window collects external light, the window can prevent the light from being too strong and stimulate human eyes.
Referring to fig. 6, fig. 6 is a schematic diagram of a fourth operation scenario of the display device 100 according to the embodiment of the application.
Taking the first display area 110 as an example, the first color-changing area 112, the second color-changing area 113, the third color-changing area 114 and the non-color-changing area 111 are included.
The first display area 110 shown in fig. 6 is different from the first display area 110 shown in fig. 3 in that a second color-changing area 113 and a third color-changing area 114 are added between two adjacent first color-changing areas 112, so that the area of the non-color-changing area 111 shown in fig. 3 is reduced, that is, the added second color-changing area 113 and third color-changing area 114 occupy the area of the non-color-changing area 111 shown in fig. 3.
When the external light is incident to the first display area 110 from the same angle, the controller may drive the working states of the pixels in one or more color-changing areas according to the light intensity detected by the light sensor, for example, when the external light is weaker, the controller may drive the color displayed by the first color-changing area 112 to be black, and the second color-changing area 113, the third color-changing area 114 and the non-color-changing area 111 have no color; when the external light is enhanced, the controller can drive the first color-changing area 112, the second color-changing area 113 or the third color-changing area 114 to display black color, and the third color-changing area 114 or the second color-changing area 113 and the non-color-changing area have no color; when the external light is very strong, the controller may drive the first color-changing region 112, the second color-changing region 113, and the third color-changing region 114 to display black, and the non-color-changing region 111 has no color. It can be understood that, according to the different external light intensities, the controller can control the first display area 110 to form blinds with different degrees of density, i.e. set up multiple adjustment modes to adapt to different light scenes, so as to achieve the protection of eyes under different light intensities, and further protect the safety of drivers.
Of course, the first color-changing region 112, the second color-changing region 113, and the third color-changing region 114 may be respectively displayed with different colors. For example, the first color-changing region 112 may display black, the second color-changing region 113 may display blue, and the third color-changing region 114 may display light blue.
Thus, the light transmittance corresponding to the different color-changing regions is different, for example, when the external light is directly incident to the first color-changing region 112 at an angle of 90 degrees, the first color-changing region 112 shows black. When external light is obliquely incident on the second color-changing region 113 at an angle of 120 degrees, the second color-changing region 113 exhibits blue color. When the external light is obliquely incident on the third color-changing region 114 at an angle of 150 degrees, the third color-changing region 114 shows a light blue color.
It should be noted that, for different color-changing regions, the colors generated by the target pixels of the different color-changing regions may be different, and the colors generated by the target pixels of the different color-changing regions may be the same.
In some embodiments, the controller may change the distribution densities of the first color-changing region 112, the second color-changing region 113, the third color-changing region 114, and the non-color-changing region 111 according to the actual change in external light. When the external light is strong, the controller is used for controlling the distribution density of the first color-changing area 112, the second color-changing area 113 and the third color-changing area 114 to be higher, and the distribution density of the non-color-changing area 111 to be lower. When the external light is weakened, the controller controls the distribution density of the first color-changing area 112, the second color-changing area 113 and the third color-changing area 114 to be lower, and the distribution density of the non-color-changing area 111 to be higher.
It should be noted that, in the embodiment of the present application, the display device 100 may be applied to a front windshield of an automobile, where the first display area 110 may be used to block relatively intense solar rays, and the second display area 120 may block solar rays reflected by a road beach, so that the light entering the eyes of a driver is soft.
Referring to fig. 7, fig. 7 is a flowchart illustrating a control method of a display device according to an embodiment of the application. The control method of the display device may include the steps of:
210. and acquiring the angle and intensity of the light rays irradiated into the display device by the external light rays outside the display device.
In some embodiments, the electronic device may obtain the light intensity and the light angle of the external light through the light sensor.
220. If the light intensity is greater than the preset light intensity threshold, determining a plurality of target pixels in a display area of the display device according to the light angle and the light intensity.
If the light intensity of the external light is larger than the preset light intensity threshold, the external light is stronger, and if the external light directly irradiates human eyes, the human eyes are stimulated, and even the vision of the human eyes is damaged.
At this time, a plurality of target pixels may be determined in a display area of the display device according to the light angle and the light intensity. For example, when the light intensity is greater than the preset light intensity threshold, the light intensity range in which the light intensity is located may be determined.
