Description
Technical field
The present invention relates to display technology field, more particularly to a kind of Mura compensation methodes of liquid crystal display device and liquid crystal
Showing device.
Background technology
Liquid crystal display device (Liquid Crystal Display, LCD) has thin fuselage, power saving, radiationless etc. numerous
Advantage, it is widely used.Liquid crystal display device major part on existing market is backlight liquid crystal display device, and it is wrapped
Include liquid crystal display panel (LCD panel) and backlight module (Backlight Unit, BLU).Usual liquid crystal display panel is by coloured silk
Film (Color Filter, CF) substrate, thin film transistor (TFT) (Thin Film Transistor, TFT) array base palte, it is sandwiched in color film
Liquid crystal (Liquid Crystal, LC) and sealing glue frame (Sealant) composition between substrate and thin-film transistor array base-plate,
Its operation principle is to place liquid crystal molecule among the parallel glass substrate of two panels, whether is powered by glass substrate to control liquid
Brilliant molecularly oriented, the light of backlight module is reflected into generation picture.
As LCD develops towards lighter, thinner, bigger direction, because of some uncontrollable factors on actual processing procedure, make
The physical characteristic of LCD display panel everywhere has differences, and causes in the range of more than one pixel, shows pure gray level image
When brightness disproportionation one phenomenon, i.e., the Mura phenomenons alleged by industry.Mura phenomenons have become the bottleneck for restricting LCD development.It is logical
Cross the probability of happening for improving technological level or Mura phenomenons being reduced the methods of improving material purity.
For the LCD display panel (Panel) to have completed, its physical characteristic has been shaped, in order to make up LCD systems
Flaw in journey and caused Mura phenomenons, now can by way of grey level compensation come the brightness of correction pixels point, and then
Improve Mura phenomenons.Grey level compensation is to realize the improvement of brightness uniformity by changing the gray value of pixel:Pass through camera
The Mura situations of gray scale picture are shot, it is then determined that normal region and Mura regions in gray level image, last according to normal
The gray value in the gray value Contrary compensation Mura regions in region, when showing pure gray level image, as shown in figure 1, bright for showing
The higher pixel of degree applies relatively low gray value, for display brightness than relatively low pixel, applies higher gray value so that
The brightness of each pixel realizes the improvement of Mura phenomenons close to unanimously after grey level compensation.Usual Mura offset datas (are reduced or carried
High gray value) it is stored in the flash storage (flash memory) arranged in pairs or groups one by one with LCD display panel, TCON (screen driving plate) IC
After (integrated circuit) chip obtains Mura offset datas, LCD brightness is set to be compensated and reach normal display effect.
At present, only shipment panel, BLU is then made by television manufacturer mostly for LCD panel manufacturers, LCD panel manufacturers
, it is necessary to which the fixation BLU for making one brightness homogeneity of panel collocation very high forms interim liquid crystal display device before shipment panel, and
Mura repairings are carried out to panel, so as to avoid fixation BLU from influenceing LCD panel reality in itself because bright darkness differs greatly
Mura offset datas.
But the BLU of television manufacturer making can also have the otherness of bright darkness certainly, even if the panel of supplied materials is complete
There is no Mura, after it is arranged in pairs or groups the poor BLU of brightness homogeneity in television factory and is assembled into liquid crystal display device, display effect
It can still be influenceed by the BLU and produce Mura, so television manufacturer is also required to for the poor liquid of display effect after assembling
Crystal device carries out Mura repairings;Because the original Mura offset datas of panel in itself have been stored in by panel manufacturers
Fixed position in flash, if television manufacturer carries out Mura repairings again, BLU luminance difference can be converted into Mura
Offset data, cover and be stored in identical position in flash, will so cause the original Mura compensation numbers of panel in itself
According to loss, when liquid crystal display device is shown, although Mura caused by BLU can disappear, Mura original panel is again
It can show again, so as to influence the overall display effect of liquid crystal display device.
The content of the invention
