Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a pixel compensation method according to an embodiment of the invention. Specifically, the method of the embodiment of the present invention may be specifically applied to a terminal, a display screen of the terminal is composed of at least one screen pixel, each screen pixel includes a red sub-pixel (R), a green sub-pixel (G), and a blue sub-pixel (B), and the screen pixel further includes a white sub-pixel. As shown in fig. 1, the pixel compensation method according to the embodiment of the present invention may include the following steps:

In a specific embodiment, the preset white subpixel is controlled to be started by detecting the attenuation (aging) state of the blue subpixel. Optionally, the attenuation state may be determined by detecting a duration of use of the blue sub-pixel, or may be determined by detecting a duration of screen-on of the terminal, or may be determined in other manners, which is not limited in the embodiment of the present invention.
102. And judging whether the current attenuation state of the blue sub-pixel point meets a preset compensation condition or not.
Optionally, when determining whether the current attenuation state of the blue sub-pixel meets the preset compensation condition, whether the preset compensation condition is met may be determined by detecting whether the service time of the blue sub-pixel reaches a certain preset threshold, or by detecting whether the screen-on time of the terminal reaches another preset threshold. I.e. when the threshold is reached it is determined that the compensation condition is fulfilled, step 103 may be performed; otherwise, the compensation condition is not satisfied, and the steps 101 to 102 may be repeatedly executed until the attenuation state of the blue sub-pixel is detected to satisfy the compensation condition.
103. And lightening a white sub-pixel point in the screen pixel so as to compensate the light emission of the blue sub-pixel point through the white sub-pixel point.
It should be understood that the lighting of the white subpixel means that the white subpixel is called to compensate the light emission of the blue subpixel when the blue subpixel is used, that is, the blue subpixel and the white subpixel need to be started and lighted. The white sub-pixel point set by the terminal can be controlled by independent driving.
Furthermore, when the white sub-pixel point is lightened, the gray scale value output by calling the white sub-pixel point can be determined according to different attenuation degrees of the blue sub-pixel point. Therefore, a gray scale value compensation table can be preset, and the gray scale value compensation table comprises compensation gray scale values corresponding to different attenuation states of the blue sub-pixel points respectively. Then, the lighting of the white sub-pixel point in the screen pixel may specifically be: finding out a compensation gray scale value corresponding to the current attenuation state of the blue sub-pixel point from the gray scale value compensation table; and calling a white sub-pixel point in the screen pixel to output the searched compensation gray scale value. Therefore, different gray-scale values which need to be output by the white sub-pixel point, namely the compensation gray-scale value, can be determined according to different attenuation states of the blue sub-pixel point, and the luminance and chrominance compensation of the OLED blue luminescent material is more intelligent and accurate.

Specifically, the attenuation state of the blue sub-pixel may be determined according to the usage duration of the blue sub-pixel, and the gray-scale value compensation table may include a plurality of usage duration intervals corresponding to the attenuation states of the blue sub-pixel, and a compensation gray-scale value corresponding to each of the usage duration intervals. Each of the usage duration intervals may be a time period, and the time periods included in the usage duration intervals are not overlapped with each other.
202. And counting the service time of the blue sub-pixel points in the screen pixels.
203. And detecting whether the counted using time exceeds a preset first time threshold.
204. And determining that the current attenuation state of the blue sub-pixel point meets a preset compensation condition.
Optionally, whether compensation needs to be performed by lighting the white sub-pixel point can be determined by detecting the lighting duration of the blue sub-pixel point. Then, the counting of the service time of the blue sub-pixel point in the screen pixel may specifically be: acquiring the state of a blue sub-pixel point in the screen pixel, wherein the state comprises a light-emitting state and a non-light-emitting state; when the blue sub-pixel point is in a non-luminous state, stopping timing; when the state of the blue sub-pixel point is a luminous state, counting the luminous time of the blue sub-pixel point, and taking the luminous time as the use time of the blue sub-pixel point. Specifically, step 204 may be executed when it is detected that the usage duration of the blue sub-pixel exceeds the first time threshold; and if not, continuously counting the service time of the blue sub-pixel point. The lighting time is the accumulated time when the blue sub-pixel point is detected to be in the lighting state (the accumulated time is not counted when the blue sub-pixel point is in the non-lighting state), so that the accuracy of the white sub-pixel point starting time for compensation is improved.
205. And searching out a compensation gray scale value corresponding to the current attenuation state of the blue sub-pixel point from the gray scale value compensation table.
206. And calling a white sub-pixel point in the screen pixel to output the searched compensation gray scale value.
Specifically, when the white sub-pixel is lighted, the gray scale value output by calling the white sub-pixel can be determined according to different attenuation degrees of the blue sub-pixel, such as the use duration of the blue sub-pixel, specifically, the use duration interval of the current use duration of the blue sub-pixel can be found out from a preset gray scale value compensation table, and the brightness and chroma compensation is performed on the blue sub-pixel by determining the compensation gray scale value corresponding to the use duration interval. Therefore, different gray-scale values which need to be output by the white sub-pixel point, namely the compensation gray-scale value, can be determined according to different using durations of the blue sub-pixel point, and the luminance and chrominance compensation of the OLED blue luminescent material is more intelligent and accurate.
In the embodiment of the invention, when the current use duration of the blue sub-pixel exceeds the preset time threshold value, the gray-scale value compensation table which comprises the compensation gray-scale values corresponding to different attenuation states of the blue sub-pixel is preset, the compensation gray-scale value corresponding to the current attenuation state such as the use duration is triggered to be obtained from the gray-scale value compensation table, the white sub-pixel is called to output the compensation gray-scale value to perform brightness compensation on the light emission of the blue sub-pixel, the attenuation of the blue pixel caused by long-time use is compensated, and the brightness uniformity of the terminal display screen is improved.
Further, referring to fig. 3, fig. 3 is a schematic flow chart of another pixel compensation method according to an embodiment of the invention. Specifically, the method of the embodiment of the present invention may be specifically applied to the terminal, where a display screen of the terminal is composed of at least one screen pixel, each screen pixel includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and the screen pixel further includes a white sub-pixel. As shown in fig. 3, the pixel compensation method according to the embodiment of the present invention may include the following steps:
301. and presetting a gray level value compensation table, wherein the gray level value compensation table comprises compensation gray level values respectively corresponding to different attenuation states of the blue sub-pixel points.
Specifically, the attenuation state of the blue sub-pixel may be determined according to the screen-on duration of the terminal, and the gray-scale value compensation table may include a plurality of screen-on duration intervals corresponding to the attenuation states of the blue sub-pixel, and a compensation gray-scale value corresponding to each screen-on duration interval. Each of the bright screen duration intervals may be a time period, and the time periods included in the usage duration intervals are not overlapped with each other.

303. And detecting whether the counted screen-on duration exceeds a preset second time threshold.
304. And determining that the current attenuation state of the blue sub-pixel point meets a preset compensation condition.
Optionally, it may also be determined whether compensation needs to be performed by lighting the white sub-pixel by detecting the screen-on duration of the terminal display screen. Specifically, the screen-on duration may refer to a lighting state of the terminal display screen, and if an accumulated duration (which is not counted when the screen is turned off) exists when any screen pixel is lit (or a screen higher than a preset percentage is lit), it may be determined that the attenuation of the blue sub-pixel point is too large when the counted screen-on duration, that is, the accumulated duration exceeds a preset time threshold, which indicates that the blue sub-pixel point needs to be compensated through a preset white sub-pixel point, and then step 304 may be executed. Otherwise, the screen-on duration is continuously counted.
305. And searching out a compensation gray scale value corresponding to the current attenuation state of the blue sub-pixel point from the gray scale value compensation table.
306. And calling a white sub-pixel point in the screen pixel to output the searched compensation gray scale value.
Specifically, when the white sub-pixel point is lightened, the gray scale value output by the white sub-pixel point is called and can be determined according to different attenuation degrees of the blue sub-pixel point, such as the bright screen duration of the terminal display screen, specifically, the bright screen duration interval where the current bright screen use duration of the display screen is located can be found out from a preset gray scale value compensation table, and the bright chroma compensation is carried out on the blue sub-pixel point according to the compensation gray scale value corresponding to the bright screen duration interval. Therefore, different gray-scale values needing to be output by the white sub-pixel points can be determined according to different screen-lighting durations of the terminal display screen, namely the compensation gray-scale values are obtained, and the intelligent and accurate luminance and chrominance compensation of the OLED blue light-emitting material is achieved.
In the embodiment of the invention, when the fact that the bright screen duration of the terminal display screen exceeds the preset time threshold is detected, the gray scale value compensation table which comprises compensation gray scale values corresponding to different attenuation states of the blue sub-pixel points respectively is triggered to acquire the compensation gray scale value corresponding to the current attenuation state such as the bright screen duration from the gray scale value compensation table, the white sub-pixel points are called to output the compensation gray scale value to perform bright-chroma compensation on the light emission of the blue sub-pixel points, and the attenuation of the blue pixel points caused by long-time use is compensated, so that the uniformity of the bright-chroma of the terminal display screen is improved.

Each of the bright screen duration intervals may be a time period, and the time periods included in the usage duration intervals are not overlapped with each other. The detection module 11 can also detect the screen-on duration of the terminal display screen to determine whether compensation needs to be performed by lighting up the white sub-pixel. Specifically, the screen-on duration may refer to a state that the display screen of the terminal is turned on, and if there is an accumulated duration when any screen pixel is turned on (the accumulated duration is not counted when the screen is turned off), it may be determined that the attenuation of the blue sub-pixel point is too large when the screen-on duration counted by the detection module 11, that is, the accumulated duration exceeds a preset time threshold, and the blue sub-pixel point is compensated by the white sub-pixel point that needs to be preset.
