Embodiment Construction

[0034] As mentioned in the background technology, the display panel in the related art has the problem of color shift in the sub-screen area. The inventors found that the reason for this problem is that in order to ensure the shooting effect of the camera module under the sub-screen area, the sub-screen area The screen area and the main screen area are often different in terms of materials, pixel density, etc., and the brightness attenuation degree of the main screen area and the auxiliary screen area are different, resulting in a significant difference in the brightness of the main screen area and the auxiliary screen area as the use time of the display panel increases. . Normally, the brightness decay of the sub-screen area is usually faster than that of the main screen area, and the sub-screen area has a color shift relative to the main screen area.

[0035] In view of the above defects, the present application provides an improved technical solution, in which, according to...

Abstract

The invention provides a brightness compensation method, a brightness compensation device and a brightness compensation system of a display panel, relates to the technical field of display, and is used for solving the technical problem of color cast of an auxiliary screen area. The brightness compensation method of the display panel comprises the following steps: acquiring at least two of the actual temperature, the actual frame rate and the actual display brightness value of the display panel and the working time of the display panel; according to at least two of the acquired actual temperature, the actual frame rate and the actual display brightness value, the working time and a pre-stored corresponding relation of brightness compensation coefficients along with time, acquiring a brightness compensation coefficient corresponding to a secondary screen area; and performing brightness compensation on the secondary screen area according to the brightness compensation coefficient. By comprehensively considering a plurality of factors influencing brightness attenuation, such as temperature, frame rate, display brightness value and the like, and reflecting the factors in the brightness compensation coefficient, the brightness of the auxiliary screen area is compensated more comprehensively and accurately, the color cast degree of the auxiliary screen area is reduced, and the brightness uniformity of the display panel is improved, so that the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a brightness compensation method, a brightness compensation device and a brightness compensation system of a display panel. Background technique [0002] With the development of display technology, a display panel with a higher screen-to-body ratio can provide a better visual experience, and has gradually become a mainstream development direction. In order to increase the screen-to-body ratio of the display panel, functional devices such as a camera module are generally arranged below the display panel. [0003] In related technologies, the display panel includes a main screen area and a secondary screen area, and the secondary screen area is opposite to the camera module. When the camera module is in use, the secondary screen area does not display images, so that the camera module can shoot through the secondary screen area; when the camera module is not in use, ...
