Device and method for adjusting imaging performance

Abstract

The embodiment of the invention provides an adjusting device and an adjusting method of development performance. A reference voltage input port is formed in a display module and is connected with a reference voltage feedback signal line, wherein the reference voltage input port is used for inputting voltage serving as data display reference to the display module; the reference voltage feedback signal line is used for outputting a signal of reference voltage fed back in real time after the display module outputs a data signal; the device comprises an acquisition module and a first adjusting module; the acquisition module is used for acquiring a first signal output by the reference voltage feedback signal line within a first time period after the reference voltage input port starts to input an ideal reference voltage signal; and the first adjusting module is used for adjusting an input signal of the reference voltage input port according to the first signal. The adjusting device and the adjusting method support adjusting of the development performance of the display module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a device and method for adjusting imaging performance. Background technique [0002] Due to the existence of parasitic capacitance in the design of liquid crystal display, due to the existence of parasitic capacitance in the display process, in the actual working process, when the voltage of the signal output changes, the change of voltage will pass through the parasitic capacitance between the data line and the pixel electrode, etc. At the same time, due to the coupling effect of the liquid crystal capacitance, the reference voltage (Vcom) will shift, resulting in a deviation between the ideal Vcom and the actual Vcom, which will affect the display performance of the liquid crystal display. For example, this This kind of deviation will make the positive and negative display areas appear asymmetrical with respect to Vcom, and when loaded for a long time, it will cause DC compone...

For example, this This deviation will cause the positive and negative display areas to be asymmetrical with respect to Vcom, and when loaded for a long time, it will cause DC components to be generated on the electrodes on the pixels, resulting in afterimages
