Problems solved by technology

However, by adding or subtracting the minimum voltage adjustment unit, it is impossible to find a better common electrode voltage such as a 255-point grayscale, or the found common electrode voltage has a large deviation, which affects the adjustment effect of the automatic gamma adjustment, and then affects the display panel. Display effect, and increase the flicker of the display panel

Abstract

The invention provides a display panel and an adjustment method thereof. The adjustment method comprises the steps of obtaining an initial gamma setting value of the display panel; adjusting the common electrode voltage corresponding to all binding point grayscales on a scintillation test screen of the first boundary binding point grayscale; obtaining the brightness of the second boundary bindingpoint grayscale and the first boundary binding point grayscale, and calculating the estimated brightness of the other binding point grayscales; adjusting a gamma setting value of the corresponding binding point grayscale according to the estimated brightness of the other binding point grayscales; and judging whether the gamma setting values of all binding point grayscales are within a range of 2.2+ / -0.2 or not, if so, ending the adjustment, and if not, carrying out readjustment.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and an adjustment method thereof. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, thin film transistor liquid crystal display device), has the advantages of low cost, low power consumption and high performance, and is widely used in the fields of electronics and digital products. important display platform. [0003] Usually, the gamma value of the panel of the display device is between 2.2±0.3, but in general, the gamma value will be shifted to about 2.2±0.8 due to the slight deviation in the process capability of the panel factory. The optimal common electrode voltage ranges are different for different gray scales of binding points. Wherein, some tie-point grayscales have multiple corresponding preferred common electrode voltages, that is, the preferred common electrode voltages of these tie-point grayscales have a wider range, ...
