Description
Technical field
The present invention relates to display field more particularly to a kind of method, collocation structure and the displays of display device compensation calculation
Device.
Background technique
Current image processing techniques be the display area on liquid crystal display panel is divided into many pixels (Pixel), and
The trichromatic sub-pixel such as red, green, blue is all had in each pixel.Since the color of all visible lights can be by red, green, blue three
The mixing of coloured light line generates, therefore the light and shade by controlling those red, green, blue sub-pixels, can build up the wanted table of pixel
Existing color, in order to more suitably describe color, International Commission on Illumination (International Commission on
Illumination, abbreviation CIE) propose CIE 1931XYZ color space (CIE XYZ Color Space).And color is empty
Between using three kinds of colors of red, green and blue as three kinds of primary colors, every other color can be mixed to form by three kinds of primary colors, and be owned
Color be all to show various colors with X, Y and Z tristimulus values with three kinds of different ratios of primary colors.
Liquid crystal display (Liquid Crystal Display, LCD) is the display device of planar ultra-thin, it is by certain
The colour or monochrome pixels of quantity form, and are placed in front of light source or reflecting plate.Liquid crystal display power consumption is very low, and has
High image quality, small in size, light-weight feature, therefore favored by everybody, become the mainstream of display.Liquid crystal display is extensive
It is used in various electronic products, for example, computer installation, mobile phone or the digital frame etc. of tool display screen, and extensively regard
Angle technology is one of the development priority of current liquid crystal display.However, when the visual angle of side view or strabismus is excessive, wide viewing angle liquid crystal
Colour cast (color shift) phenomenon can often occur for display.
As under the increasing trend of the screen of display, the viewing angle characteristic of display is the one of display color superiority and inferiority
Item important indicator, it is however generally that, the visual angle color of VA (Vertical Alignment liquid crystal) type liquid crystal display
It spends deviation (color difference), it, can be compared with IPS (In-Plane because the birefringence effect of liquid crystalline is different
Switching) the visual angle chromaticity distortion of type liquid crystal display is big, causes VA type liquid crystal display in the case where big visual angle, draws
The case where face is easy whiting (color wash-out) compared with IPS panel, therefore, viewing angle compensation technology shows VA type
For device, it appears it is comparable important, wherein comprising azimuth (ψ: 0~360degree) compensation and solid angle (θ: 90~-
Compensation 90degree), it is however generally that, VA escope can be reached with multizone (multi-domain) pixel design technology
The purpose of viewing angle compensation, wherein can more be divided into 4 domains (4-domain), picture element compensation more than 8 domains (8-domain) or 8 domains,
Picture element compensation in usual 4 domain is used to compensate the azimuth of display, and the above picture element Compensation Design in 8 domains can then compensate solid angle again.
In general, compensating display azimuth and solid angle using multizone (multi-domain) pixel design
Technology, it is necessary to more points of sub-regions (domain) in a sub-pixel (sub-pixel), and must be set to different liquid
Crystalline substance operation voltage, is generally divided into clear zone and dark space, however, in order to realize zonal control, it is necessary to mostly one derided capacitors of design,
Or more one active array switch of design carry out independent control, cause the aperture opening ratio of whole picture element that can therefore decline；Therefore, separately
The neighbouring picture element of display is carried out Perspective Analysis, is not being influenced just by a kind of viewing angle compensation technology using special visual angle algorithm
Under the gamma characteristic at visual angle, the bright dark distribution of picture element, the viewing angle characteristic of Lai Youhua display are rearranged.
The method that display viewing angles are traditionally compensated using viewing angle compensation algorithm, will not spatially lose display
Aperture opening ratio, but compared with subregion pixel design technology, the viewing angle compensation technology using algorithm is with RGB sub-pixel for control
Unit processed, subregion picture element technology are then to be divided into the area the A sub-pixel and area B sub-pixel in the sub- picture element of sub-pixel,
Therefore, spatially the control unit of subregion picture element is small compared with what the viewing angle compensation technology of algorithm was come, visually, subregion picture element skill
Art is less susceptible to see bright dark sub-pixel distribution, is commonly called as granular sensation.Under the picture of high frequency, such as lines, font, object edge
Deng, the technology for utilizing an algorithm to compensation visual angle is easy to have that lines are unintelligible, and there is the case where colour cast at font edge, therefore,
In general, compensating the technology at visual angle using algorithm, meeting image application edge detection technology carrys out the high frequency region of detecting image
Domain, and in this high-frequency region, weaken or turn off algorithm compensation technology, to reduce because of adverse effect caused by viewing angle compensation.
However, due to that must reduce the colour cast at visual angle, in the case where short distance is watched, picture has granular sensation in low frequency region.
