Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, specific embodiments of a method and an apparatus for driving a display panel according to an embodiment of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only for illustrating and explaining the present invention and are not to be used for limiting the present invention. And the embodiments and features of the embodiments may be combined with each other without conflict. It should be noted that the sizes and shapes of the figures in the drawings are not to be considered true scale, but are merely intended to schematically illustrate the present invention. And the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
Generally, the gamma tuning process of the display panel is to perform white balance correction only on the physical center area of the display panel (i.e., to calibrate the brightness and color coordinates of the whitest picture (255 gray scale)). However, in the process of manufacturing the display panel, the display panel may have non-uniformity due to the difference of the process, resulting in poor display effect. For example, in an Organic Light Emitting Diode (OLED), due to process variation, the Film thickness of the Light Emitting material layer in the OLED may vary in different regions, and the characteristics of the Thin Film Transistor (TFT) may vary in different regions. Thus, when some pixels in the display panel display the most white luminance, there may be a luminance difference, resulting in a poor display effect.
In view of this, the driving method of the display panel provided in the embodiment of the invention, as shown in fig. 1, may include the following steps:
s101, receiving image data of a picture to be displayed; wherein the image data includes: data corresponding to the sub-pixels of the multiple colors;
s102, adjusting each data corresponding to the target color sub-pixel in the pixel unit which is to display the whitest brightness according to the pre-established relationship among the pixel area, the target color sub-pixel, the preset coefficient and the data corresponding to the target color sub-pixel; the display area of the display panel is divided into a plurality of pixel areas which are arranged in an array, and a target color sub-pixel in each pixel area corresponds to a predetermined preset coefficient;
and S103, controlling a display panel to display according to the adjusted data.
In the driving method of the display panel provided by the embodiment of the present invention, the image data of the picture to be displayed is received, and each data corresponding to the target color sub-pixel in the pixel unit that displays the whitest brightness is adjusted according to the relationship among the pre-established pixel area, the target color sub-pixel and the preset coefficient, and then the display panel is controlled to display according to the adjusted data. Therefore, the color to be displayed by the pixel unit with the whitest brightness to be displayed in the image to be displayed can be adjusted, so that the image to be displayed meets the specification required by the display panel, and the display effect is improved.
In specific implementation, in the embodiment of the present invention, a relationship among the pre-established pixel region, the target color sub-pixel, the preset coefficient, and the data corresponding to the target color sub-pixel satisfies a formula: p_c-k＝a_c-kQ_c-k；
Wherein K is more than or equal to 1 and less than or equal to K and is an integer, K represents the total number of pixel regions, c represents the color of a sub-pixel, a_c-kWhen the sub-pixel representing the target color is c color, the corresponding preset coefficient, P, in the k-th pixel area_c-kWhen the sub-pixel of the target color is c color, the adjusted data Q corresponding to the sub-pixel of the target color in the k-th pixel region_c-kWhen the target color sub-pixel is represented as the c color, the data before adjustment corresponding to the target color sub-pixel in the kth pixel area. The above values may be designed and determined according to the actual application environment, and are not limited herein.
Generally, the display area of the display panel may include a plurality of pixel units, each pixel unit includes a plurality of color sub-pixels, so that color mixing may be performed by the sub-pixels to realize picture display. For example, the pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, so that the image display may be realized by mixing red, green, and blue colors. For example, color mixing is performed by red, green, and blue to realize white screen display or color screen display.
In specific implementation, in the embodiment of the present invention, as shown in fig. 2, the display area AA of the display panel may be divided into a plurality of pixel regions S _ k arranged in an array. Each pixel region S _ k may include the same number of pixel units. For example, K — 12, the pixel regions S _1 to S _12 may include 4 × 4 pixel cells P1 to P16. Alternatively, each pixel region may include 1 pixel unit. Alternatively, each pixel region may also include 2 × 2 pixel units. Alternatively, each pixel region may also include 3 × 3 pixel units. Of course, in practical applications, the number of pixel units included in each pixel region S _ k may also be determined according to practical application environments, and is not limited herein.
The present invention will be described in detail with reference to specific examples. It should be noted that the present embodiment is intended to better explain the present invention, but not to limit the present invention.
The first embodiment,
In practical implementation, in the embodiment of the present invention, the target color may include red, that is, c ═ 1, so that the target subpixel includes a red subpixel. As shown in fig. 2, each red sub-pixel in each pixel region S _ k corresponds to a predetermined coefficient a_1-k. For example, the red sub-pixel in the pixel region S _1 corresponds to a predetermined preset coefficient a_1-1The red sub-pixel in the pixel region S _2 corresponds to a predetermined preset coefficient a_1-2The red sub-pixel in the pixel region S _3 corresponds to a predetermined preset coefficient a_1-3. The rest can be analogized, and the like, but is not limited herein. Thus, the preset coefficient a corresponding to the pixel area, the red sub-pixel and the red sub-pixel can be established in advance_1-kAnd adjusting each data corresponding to the red sub-pixel in the image data according to the relationship between the data corresponding to the red sub-pixel. Therefore, the whitest picture to be displayed can be adjusted, so that the whitest picture meets the specification required by the display panel, and the display effect is improved.
The gray scale is generally divided into several parts of the brightness variation between the darkest and the brightest so as to control the brightness of the screen. For example, the displayed image may generally be composed of three colors, red, green, and blue, to form a color image by mixing, wherein each color may exhibit a different brightness level, and the red, green, and blue of different brightness levels may be combined to form different color dots. Gray levels are the gradation levels representing the different brightness from the darkest to the brightest. The more the intermediate levels are, the more exquisite the picture effect can be presented. Currently, a typical display panel may employ a 6-bit (2 to 8 th power of brightness gradation, i.e. having 64 gray scale), a 7-bit (2 to 7 th power of brightness gradation, i.e. having 128 gray scale), a 8-bit (2 to 8 th power of brightness gradation, i.e. having 256 gray scale) panel, a 10-bit (2 to 10 th power of brightness gradation, i.e. having 1024 gray scale) panel, a 12-bit (2 to 12 th power of brightness gradation, i.e. having 4096 gray scale) panel, or a 16-bit (2 to 16 th power of brightness gradation, i.e. having 65536 gray scale) panel to realize image display. In the following, the display panel is described as including red, green, blue and 256 gray levels, but the reader should understand that the color of the sub-pixels included in the display panel is not limited thereto.

Wherein the physical center region may refer to a region where the geometric center of the display area is located. For example, the physical center area may refer to: and an area surrounded by circles which are centered at the geometric center of the display area and have a preset distance as a radius.
