[0034] see figure 2 , image 3 and Figure 4a to Figure 4dAccording to the first embodiment of the method for improving the display quality of the liquid crystal panel according to the present invention, the first embodiment includes the following steps:

[0035] Step S22: Input pixel data, make the source have an AC waveform voltage to display images. first,

[0036] image 3 After the liquid crystal panel is assembled with the backlight module and other optical components to form the liquid crystal module 30 , the detection signal source 42 and the detection power supply 44 can be supplied to the liquid crystal module 30 to perform screen display related tests. It should be noted that in the present invention, it is only necessary to have the image display function after the panel is manufactured, and it is not necessary to test after the panel is assembled with other components. image 3 The pixel data can be input to the liquid crystal module 30 by the detection sign...

Abstract

The invention provides a method for improving display quality of a liquid crystal panel, which comprises that pixel data are input to enable a source to have a source voltage with an alternating current waveform so as to display images; a sharing voltage is adjusted to a first voltage value which enables the screen flickering degree to be minimum; the first voltage value is deviated from a first offset, so that the sharing voltage reaches a second voltage value; the second voltage value and the source voltage are continuously applied to the liquid crystal panel for a preset period of time; and the sharing voltage is adjusted to a third voltage value, a second offset which is not equal to the first offset but is in the same deviating direction as the first offset exists between the third voltage value and the first voltage value, and the third voltage value is used in coordination with the source voltage to display images. The method can solve the problems of poor display quality such as residual images, flickering and the like which occur during the image display process.

Description

technical field [0001] The present invention relates to a method for improving the display quality of a liquid crystal panel, in particular to a method of applying an electric field to burn mobile ions in a liquid crystal layer to both sides of a substrate to improve the display quality of a liquid crystal panel. Background technique [0002] Existing liquid crystal displays are driven by polarity inversion to avoid the DC blocking effect of the alignment film and the DC residual voltage (DCresidual) caused by the mobile irons in the liquid crystal cell to prevent image display Image retention occurs during the process, displaying poor quality issues. [0003] Due to the parasitic capacitance effect of the thin-film transistor (thin-film transistor) charging and discharging process in the pixel, the charge will be redistributed and the voltage drop effect will occur, and the so-called kick back voltage (kick back voltage) will be generated, so that the positive and negative ...
