Display brightness adjusting method, testing method and device and display testing equipment

Abstract

The invention provides a display brightness adjusting method, a testing method and device and display testing equipment. The brightness adjusting method comprises the following steps: detecting whether a light guide plate of a display is injured or not; when the light guide plate is injured, judging the injury position and the injury degree of the light guide plate; and adjusting the brightness of the display corresponding to the injury position to compensate a brightness change value generated by the injury according to the preset corresponding relation between the injury degree and the brightness change value. The testing method comprises the following steps: carrying out destructive operation on the to-be-tested display; detecting the injury degree caused by the destructive operation and the brightness change value which is correspondingly generated in an injury area; and building and storing the corresponding relation between the injury degree and the brightness change value. The display brightness adjusting device, the display and the testing device comprise corresponding modules and corresponding devices. The mechanical injuries of drop, collision and the like can be prevented from affecting the display brightness of the display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display brightness adjustment method, a test method and device, and display test equipment. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) is a display product widely used in various electronic devices with displays in the prior art, such as mobile phones. Traditional LCD products used in mobile phones often encounter mechanical collisions such as falling during use. Due to repeated collisions and frictions by components on the mobile phone, such as batteries, etc., the light guide plate of the LCD will cause certain damage. Other electronic products with displays may also be dropped or collided during use. No matter what kind of display, it will be damaged after being subjected to a certain degree of mechanical collision, which will affect the display of the user's display screen, such as making the screen image Bright spots appear, which ...
