Problems solved by technology

[0003] Each TFT-LCD has a target reference voltage. When working under the target reference voltage, the flicker value of the TFT-LCD is the smallest and the working state is the best. Due to the differences between TFT-LCDs, the target reference voltage of each TFT-LCD There will be slight differences in voltage. When mass-producing TFT-LCDs, if all TFT-LCDs use the same reference voltage, the flicker value of some TFT-LCDs will be too large and the display effect will not be good.

Abstract

The embodiment of the invention provides a method for determining reference voltage of a display screen. The device comprises a first measurement unit, a first judgment unit, a second measurement unit, a second judgment unit and a first determination unit, wherein the first measurement unit is used for measuring a current level flicker value under current level reference voltage of the display screen; the first judgment unit is used for judging whether the current level flicker value is smaller than a superior flicker value; the superior flicker value is the measured flicker value of the display screen under the superior reference voltage, and the superior reference voltage is lowered according to preset quantity to obtain the current level reference voltage; if the current level flicker value is smaller than the superior flicker value, the current level reference voltage is lowered according to the preset quantity to obtain lower level reference voltage; the second measurement unit is used for measuring the low level flicker value under the low level reference voltage of the display screen; the second judgment unit is used for judging whether the low level flicker value is smaller than the current level flicker value; if the low level flicker value is greater than the current level flicker value, the first determination unit is used for determining the current level reference voltage as target reference voltage. By implementing the embodiment of the invention, the display effect of the display screen can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a device for determining a reference voltage of a display screen. Background technique [0002] At present, electronic devices such as mobile phones and tablet computers use Thin Film Transistor-Liquid Crystal Display (TFT-LCD) in large quantities. TFT-LCD is used in mobile phones and other terminals due to its fast response speed and large viewing angle. has been widely applied. [0003] Each TFT-LCD has a target reference voltage. When working under the target reference voltage, the flicker value of the TFT-LCD is the smallest and the working state is the best. Due to the differences between TFT-LCDs, the target reference voltage of each TFT-LCD There will be slight differences in voltage. When mass-producing TFT-LCDs, if all TFT-LCDs use the same reference voltage, the flicker value of some TFT-LCDs will be too large and the display effect will not be good. Contents of the...
