Detailed Description
The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto.
In order to further improve the problem of side-view color cast of the display panel, the embodiment of the invention provides a pixel matrix driving method and a display device; the main implementation body of the pixel matrix driving method provided by the embodiment of the invention is the display device provided by the embodiment of the invention, and the device can be applied to electronic equipment. In a specific application, the electronic device may be any device including a display panel, such as a desktop computer, a portable computer, an intelligent mobile terminal, a liquid crystal television, and the like. The display panel includes a liquid crystal display panel, a liquid crystal touch panel, and the like.
First, a pixel matrix driving method provided by an embodiment of the present invention will be described in detail. In the method, each data line of a pixel matrix controls the driving voltage of sub-pixels positioned at two sides of the data line, X adjacent sub-pixels are arranged between the sub-pixels controlled by the single side of each data line in a pairwise interval mode, the adjacent sub-pixels refer to the sub-pixels on the adjacent data lines of each data line, and X is a positive integer.
It is understood that a pixel matrix is a matrix made up of individual sub-pixels; any sub-pixel can be an R sub-pixel, a G sub-pixel or a B sub-pixel, and each 3R sub-pixels, G sub-pixels and B sub-pixels correspond to one pixel on the display panel.
Fig. 1 exemplarily shows a pixel matrix in which a plurality of data lines are arranged in a longitudinal direction, and a first data line and a last data line in a scan line direction are connected together to form the same data line; as can be seen from fig. 1, each data line controls a plurality of sub-pixels located at both sides of the data line, and every two sub-pixels controlled at one side of each data line are spaced by 1 neighboring sub-pixel. It can be understood that, in fig. 1, for the data line formed by connecting the first data line and the last data line, the sub-pixel controlled by one side of the data line is located at the right side of the first data line, and the sub-pixel controlled by the other side of the data line is located at the left side of the last data line. In this way, the arrangement of the sub-pixels in the pixel matrix can be made regular.
As shown in fig. 2, the pixel matrix driving method provided by the embodiment of the invention may include the following steps:
s10: image data is received.
Here, the image data refers to a frame of digital images received by the display panel, and the original pixel data including RGB pixel values of each pixel of the digital images corresponding to the image data can be obtained by analyzing the image data; if the driving voltages for the sub-pixels are generated directly according to the RGB pixel values and are imaged on the display panel, a severe color shift will occur in the side view direction of the display panel. Therefore, the RGB pixel values included in the original pixel data need to be adjusted, so as to improve the color shift problem in the side-view direction of the display panel.
S20: and generating gray scale data of each sub-pixel in the pixel matrix according to the image data and a preset sub-pixel bright-dark alternative arrangement mode.
Specifically, the image data received in step S10 is parsed into original pixel data; and then, processing the gray scale of the sub-pixels on the original pixel data according to a preset sub-pixel bright-dark alternative arrangement mode to obtain the gray scale data of each sub-pixel in the pixel matrix. It is understood that the original pixel data is processed according to the preset light-dark alternative arrangement of the sub-pixels, i.e. the RGB pixel values contained in the original pixel data are adjusted. For example, if the gray scale of a sub-pixel is calculated as a according to the original pixel data, and the gray scale of the sub-pixel should be B according to the setting of the alternating arrangement of the bright and dark sub-pixels, the gray scale of the sub-pixel is B in the generated gray scale data.
In the alternative arrangement mode of the bright and the dark of the sub-pixels, the gray scale of the sub-pixels at least comprises 3 levels, and the gray scale of each row of the sub-pixels of the pixel matrix is in an alternative arrangement state, wherein the alternative arrangement mode is one of a plurality of preset alternative arrangement modes.
S30: and generating a target driving voltage of each sub-pixel in the pixel matrix according to the gray scale data and a driving voltage polarity control mode matched with the brightness alternating arrangement mode of the sub-pixels.
Specifically, an initial driving voltage is generated according to a driving voltage value corresponding to each gray scale, and a polarity is set for the initial driving voltage according to a driving voltage polarity control mode matched with the subpixel bright-dark alternating arrangement mode, so that a target driving voltage of each subpixel in the pixel matrix is obtained.
It can be understood that, in order to implement a display scheme of at least 3-level gray scale of a sub-pixel, it is necessary to design a matched sub-pixel driving frame, that is, to design a suitable sub-pixel light and dark alternating arrangement manner and a driving voltage polarity control manner matched with the sub-pixel light and dark alternating arrangement manner, and specific implementation manners exist.
S40: the target drive voltage is loaded to the pixel matrix.
It can be understood that, the target driving voltage of each sub-pixel is applied to the corresponding sub-pixel, so that the driving of the pixel matrix is completed; accordingly, the color shift of the image displayed by the display panel in the side viewing direction is relatively small, and compared with the prior art, the color shift problem of the display panel in the side viewing direction can be well improved.
Wherein, if the gray scale level of the sub-pixel is set as Y in the alternating bright and dark arrangement of the sub-pixel, the embodiment of the invention is applied to the display panel having 4 domains in the sub-pixel, and the display panel will have 4 × Y domains with different tilt angles. For example, when Y =3, the display panel may have 12 domains with different tilt angles, and when Y =4, the display panel may have 16 domains with different tilt angles.
In the pixel matrix driving method provided by the invention, gray scale data is generated by a preset sub-pixel bright-dark alternative arrangement mode, in the gray scale data, the gray scale of the sub-pixel is set to be at least three levels, so that the whole display panel has at least 12 domains with different inclination angles; and a driving voltage polarity control mode matched with the sub-pixel brightness and darkness alternating arrangement mode is matched to generate a target driving voltage of the pixel matrix to drive the pixel matrix, so that the side view color cast of the display panel can be further improved compared with the existing 8-Domain or ALCS technology.
The following describes an example of the alternating arrangement of sub-pixels and the control of the driving voltage polarity.
For example, in the pixel matrix driving method provided in the embodiment of the present invention, the driving voltage polarity control manner may include:
selecting a first or last sub-pixel as an initial sub-pixel aiming at sub-pixels controlled at two sides of each data line, and starting from the initial sub-pixel, forming each m sub-pixels into a group along the direction of the data line, so that the polarities of the sub-pixels in each group are the same, the polarities of the sub-pixels in adjacent groups are opposite, and the polarity of the initial sub-pixel is opposite to that of the sub-pixels in the adjacent group;
selecting a first or last sub-pixel as an initial sub-pixel aiming at the sub-pixels controlled by each scanning line of the display panel, wherein every n sub-pixels form a group along the scanning line direction from the initial sub-pixel, so that the polarities of the sub-pixels in each group are the same, the polarities of the sub-pixels in adjacent groups are opposite, and the polarity of the initial sub-pixel is opposite to that of the sub-pixels in the adjacent group; wherein m and n are both positive integers greater than 1.
It is understood that the data line direction and the scan line direction in the display panel are two directions orthogonal to each other. Specifically, if the data line direction is the longitudinal direction, the scan line direction is the transverse direction, and at this time, the sub-pixels controlled by each scan line are the sub-pixels in a row; if the data line direction is horizontal, the scan line direction is vertical, and the sub-pixels controlled by each scan line are the sub-pixels in a column.
Correspondingly, the sub-pixel bright-dark alternate arrangement mode matched with each driving voltage polarity control mode can comprise the following steps:
when the polarity of each sub-pixel of the pixel matrix is controlled according to the driving voltage polarity control mode, all sub-pixels are arranged in a bright-dark alternating mode, wherein the error between a Gamma curve of a display image in a side view direction and a Gamma curve of the display image in a front view direction is not larger than a reference error; wherein, the display image is an image output by the display panel.
In practical application, after the gray scale level is selected, the arrangement modes of various sub-pixels with alternating brightness and darkness can be obtained, and the display images can be obtained by applying the arrangement modes to a practical display panel; by drawing a Gamma curve of a display image and comparing the Gamma curve with the error between the Gamma curve in the front view direction, it can be determined which alternate arrangement mode is matched with the selected drive voltage polarity control mode, thereby selecting the sub-pixel bright-dark alternate arrangement mode as a better preset alternate arrangement mode. In addition, when the preset alternative arrangement mode is selected, the selection can be performed by referring to the visual perception of human eyes in the side-looking direction, which is reasonable. For the reference error between the Gamma curve in the side view direction and the Gamma curve in the front view direction, the calculation method and the specific numerical value of the reference error are not limited in the embodiment of the present invention.
For the sake of clarity, the following describes an exemplary driving voltage polarity control manner and a matching sub-pixel light and dark alternate arrangement manner, taking the sub-pixel including H, M1, M2 and L levels of gray scale as an example. Wherein H is more than M1 and more than M2 is more than L.
For example, the driving voltage polarity control manner may include: a first driving voltage polarity control mode; in the first driving voltage polarity control scheme, X =1,m =2,n =2. That is, in the first driving voltage polarity control manner, every two adjacent sub-pixels are spaced by 1 between the sub-pixels controlled by the single side of each data line; and for the sub-pixels controlled at two sides of each data line, after selecting the first or the last sub-pixel as the starting sub-pixel, regarding every 2 sub-pixels along the direction of the data line from the starting sub-pixel as a group, wherein the polarities of the sub-pixels in each group are the same, the polarities of the sub-pixels in the adjacent groups are opposite, and the polarity of the starting sub-pixel is opposite to that of the sub-pixels in the adjacent group; for each sub-pixel controlled by the scanning line, after the first or the last sub-pixel is selected as a starting sub-pixel, every 2 sub-pixels along the scanning line direction from the starting sub-pixel are regarded as a group, the polarities of the sub-pixels in each group are the same, the polarities of the sub-pixels in the adjacent groups are opposite, and the polarity of the starting sub-pixel is opposite to that of the sub-pixels in the adjacent group.
Referring to the example shown in fig. 3, every two of the sub-pixels controlled by one side of each data line are spaced by 1 neighboring sub-pixel; taking the data line a as an example, it can be seen that, among the 8 sub-pixels controlled by the two sides of the data line a, the first sub-pixel G at the top is selected as the starting sub-pixel, and the polarity of the starting sub-pixel is positive; from the starting sub-pixel, the 2 nd sub-pixel R and the 3 rd sub-pixel G are regarded as a group, and the polarities are negative; the 4 th sub-pixel R and the 5 th sub-pixel G are regarded as a group, and the polarities are positive; the 6 th sub-pixel R and the 7 th sub-pixel G are regarded as a group, and the polarities are negative; by analogy, the polarity of the 8 th sub-pixel R should be set to positive.
Taking the first row of sub-pixels along the scanning line direction shown in fig. 3 as an example, it can be seen that the first sub-pixel R in the row of sub-pixels is selected as the starting sub-pixel, and the polarity of the starting sub-pixel is positive; after the starting sub-pixel, regarding the 2 nd sub-pixel G and the 3 rd sub-pixel B as a group, and the polarities are negative; the 4 th sub-pixel R and the 5 th sub-pixel G are regarded as a group, and the polarities are positive; the 6 th sub-pixel B and the 7 th sub-pixel R are regarded as a group, and the polarities are negative; regarding the 8 th sub-pixel G and the 9 th sub-pixel B as a group, the polarities are positive; regarding the 10 th sub-pixel R and the 11 th sub-pixel G as a group, the polarities are negative; and so on, the polarity of the 11 th sub-pixel B should be set to positive. It is understood that in practical applications, the 11 th sub-pixel B may be grouped with the 12 th sub-pixel R, and FIG. 3 is limited to space and only shows a portion of the pixel matrix.
Correspondingly, the alternative arrangement of the brightness and the darkness of the sub-pixels matched with the polarity control manner of the first driving voltage can be seen in fig. 4; in fig. 4, 24 sub-pixels are shown in an alternating bright-dark arrangement, and each 4 × 4 square is a sub-pixel in an alternating bright-dark arrangement matching the first driving voltage polarity control.
