Abstract

The present application provides a method for adjusting brightness of a display panel and a display device, which are used to solve the problem of uneven display brightness of the display panel caused by uneven temperature of the display panel. A display panel brightness adjustment method provided by the present application includes: collecting temperature values ​​through temperature sensors distributed in multiple positions of the display panel; using the collected temperature values ​​to fit the temperature distribution of the display panel; when it is determined that the display panel needs to be adjusted During panel brightness, the brightness of the display panel is adjusted according to the temperature distribution of the display panel. The technical solution provided by the present application avoids the problem of uneven display brightness of the display panel caused by uneven temperature of the display panel, thereby improving the display effect of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for adjusting brightness of a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display device is a new type of display technology developed in the middle of the 20th century. It has many advantages such as wide range, low power consumption, low cost, strong shock resistance and flexible display. However, the OLED display panel in the prior art has the problem of uneven display brightness of the display panel caused by uneven temperature. There are many reasons for the uneven display brightness of the display panel. For example, local temperature changes with time, resulting in uneven display brightness, or uneven display brightness caused by factors such as bending of the display panel. [0003] Wherein, the uneven display brightness of the display panel caused by the bending is due to the uneven temperatu...
