Description
Technical field
The present invention relates to display device technology field, the picture adjusting method of a kind of display panels and dress
Put.
Background technology
Large scale flat panel Liquid Crystal TV more and more receives the favor of numerous consumer, and consumer is to display image
Requirement with image quality is more and more higher.Due to the inherent character of liquid crystal molecule, liquid crystal display is to need showing picture when
Wanting positive-negative polarity constantly to convert, therefore this is easy for causing the positive and negative gray scale voltage absolute value difference under different pictures relatively big,
So that the film flicker degree that human eye is felt under different pictures is the most different；Further, since liquid crystal display self
, between input voltage and output image, there is certain distortion in characteristic.In view of above 2 points, liquid crystal display is carried out float
Regulation with the distortion factor is necessary.It is adjusted liquid crystal display picture mainly considering Gamma magnitude of voltage and screen flicker degree
(Flicker).Gamma value is a kind of metric parameter describing brightness that image shows and GTG non-linear relation, Flicker table
Levy the flashing state of display screen.
The Gamma standard of human eye is 2.2, needs Gamma value is adjusted to human eye scope in liquid crystal module production process.Often
The brightness of individual GTG is that the voltage of the generation by Gamma chip determines.Regulation Gamma value is actually regulation Gamma core
Sheet.Gamma chip can produce two groups of Gamma voltages and a V-COM voltage, and wherein V-COM is the centre of two groups of Gamma voltages
Value.Two groups of Gamma Control of Voltage 256 rank gray scale voltages, each gray scale voltage and a gray scale voltage in another group in two groups
Symmetrical on V-COM voltage both sides.This symmetrical degree determines screen flicker degree, and all gray scale voltage symmetry are the highest, then
The Flicker value of each GTG is the least.Film flicker can be reduced by the combine regulation of V-COM voltage and Gamma voltage.
The picture adjusting method of existing display panels mainly comprises the steps that
(1), drive display floater display flicker picture, constantly adjust the flicker degree of V-COM voltage debugging flicker picture, when
When flicker degree reaches predetermined value, determine optimal V-COM magnitude of voltage；
(2), drive display floater to switch to display 255 grey menu, adjust Gamma voltage and make the brightness of this picture
Greatly, high-high brightness I is obtainedmax；
(3), drive display floater to switch to display 0 grey menu, adjust Gamma voltage and make the brightness of this picture
Little, obtain minimum brightness Imin；
(4), according to high-high brightness ImaxWith minimum brightness IminCalculate acquisition standard gamma curve；
(5), driving display floater to switch to display Gamma to tie up the grey menu of point voltage, adjust correspondence ties up point voltage,
Make the requirement of the brightness conformance with standard gamma curve of corresponding picture；Generally, Gamma voltage curve includes multiple tying up an electricity
Pressure, therefore needs to be sequentially switched to each and ties up the grey menu that point voltage is corresponding in this step；
(6), again drive display floater to show such as the flicker picture of step (1), reaffirm whether flicker degree conforms to
Ask, if meeting the requirements, completing picture and adjusting；If not meeting, readjust according to as above step.
As above in method of adjustment, needing constantly to drive display floater to switch multiple display pictures, process is loaded down with trivial details, picture
The time adjusted is longer, reduces work efficiency；It addition, to each grey menu (255 grey menu, 0 grey menu and each
Individual tie up the grey menu that point voltage is corresponding) when being adjusted, it is impossible to know that the adjustment of each grey menu is to flicker picture in time
The impact in face.
