Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0053] Due to the difference in structure between the under-screen camera area and the main display area in the existing display panel, the heat dissipation effect of the under-screen camera area is better than that of the main display area, that is, the performance of the thin film transistors in the main display area is greatly degraded, resulting in The brightness of the main display area is lower than the brightness of the camera area under the...

Abstract

The invention discloses a brightness adjusting method and device of a display panel. According to the method, firstly, the working temperatures of a target panel in different areas are obtained according to the difference value of the brightness parameters of the target panel in different areas, secondly, the brightness compensation parameters of the corresponding areas are obtained according to the incidence relation of the temperature and the brightness and the difference value of the working temperatures of the different areas, and finally, the brightness compensation parameters of the target panel in the different areas are obtained according to the brightness compensation parameters. Compensating the brightness of the corresponding area; the brightness of the target area is compensated by measuring the temperature difference value of different areas in the target panel and through the incidence relation between the temperature and the brightness, so that the display brightness of the target panel in different areas is the same, and the display uniformity of the target panel is ensured.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a brightness adjustment method of a display panel and a device thereof. Background technique [0002] With the development of science and technology and the improvement of people's requirements for products, full-screen products with high screen ratio have become the highly anticipated development trend of smartphones, so the technology of under-screen camera is particularly important. [0003] However, in the existing display panel with under-screen camera, in order to ensure the transparency of the under-screen camera area in the panel, the stacked film structure in the under-screen camera area is less than that in the main display area. , so the heat dissipation effect of the camera area under the screen is better than that of the main display area. For different temperatures, there are certain differences in the performance of thin film transistors. For examp...
