Abstract

The invention relates to a display screen flicker test method comprising: obtaining a preset common voltage array comprising a plurality of common voltage values; acquiring at least one common voltage value with the highest acquisition frequency in the common voltage array as an anticipated value; subjecting a display screen to a flicker test according to the anticipated value to obtain the flicker value of the display screen; comparing the flicker value with a first preset threshold and a second preset threshold separately to obtain the common voltage value corresponding to the minimum flicker value and write the common voltage value into a driving chip of the display screen. The display screen flicker test method can shorten the time to find the best common voltage value, can improve the production efficiency and reduce product cost.

Description

technical field [0001] The invention relates to the field of display screen testing, in particular to a display screen flickering test method. Background technique [0002] As the proportion of display screens of mobile phones and tablets is increasing, more and more attention has been paid to the display effect of the display screens. In order to pursue a better experience, users hope that the viewing angle of the display screen is wider, the contrast ratio is higher, the screen is clearer, and the screen flicker (flicker) is smaller, because when the screen flicker becomes larger, it will directly affect the clarity of the display screen . And when the flickering of the picture is small enough, the picture presented on the display screen is like a still picture, and the user experience is better. Therefore, FLICKER is currently becoming an indicator that has attracted much attention. [0003] The display of the display screen is realized by flipping the liquid crystal i...
