Therefore, when the display control method of the liquid crystal display that the present invention provides can improve liquid crystal display display, periphery exists
The problem on blue limit, is conducive to improving the uniformity that liquid crystal display blue light shows.
In order to be more clearly understood that the above-mentioned technique effect of the present invention, describe by formula of mathematical below.
Δ I=(IPeriphery is revealed+INeighboring pixel shows)-ICenter pixel shows (1)
It can be seen that at I from above-mentioned formula (1)Periphery is revealedAnd ICenter pixel showsIn the case of constant, INeighboring pixel showsReduction, have
It is beneficial to reduce Δ I, the i.e. subtractive of the blue light brightness that liquid crystal display neighboring area and central area show little, so, it is possible
Improve liquid crystal display periphery and there is the problem on blue limit, be conducive to improving the uniformity that liquid crystal display blue light shows.This
Inventive embodiments is namely based on above-mentioned principle, reduces the display brightness of the blue subpixels of image element array substrates neighboring area, reaches
To improving liquid crystal display periphery and exist the problem on blue limit, and then improve the uniformity that liquid crystal display blue light shows.
Additionally, according to the relation schematic diagram between the colourity shown in Fig. 4 and back gauge, in neighboring area, distance edge
The nearest, chrominance distance stationary value is the biggest.The degree of turning blue of this neighboring area is different, and the closer to edge, degree of turning blue is the heaviest.
Due to the neighboring area at quantum dot color enhancement film, the closer to edge, degree of turning blue is the heaviest, so, in order to more
Improve well periphery to turn blue problem, in embodiments of the present invention, be applied to the blue subpixels B of image element array substrates central area
On the first voltage be constant voltage so that the brightness that shows of the blue subpixels B being positioned at image element array substrates central area is permanent
Fixed.The second voltage being applied on the blue subpixels B of image element array substrates neighboring area is voltage gradient, and from pel array
The edge of substrate is gradually increased to center, so that the brightness that the blue subpixels B being positioned at image element array substrates neighboring area shows
Gradually risen to center by edge, to reach following effect as far as possible: distance edge is nearer, blue subpixels that brightness is relatively low shows
The blue light shown adds the blue subpixels that the blue light brightness sum of the leakage that brightness is bigger is slightly higher with distance edge brightness farther out
The blue light of display is the most close plus the blue light brightness sum of the relatively low leakage of brightness, so that liquid crystal display surrounding zone
The blue light brightness that territory and central area show is close, the most preferably improves the problem that liquid crystal display periphery turns blue, and improves
Liquid crystal display show uniformity.
