Description
Technical field
The present invention relates to a kind of display and display packing thereof, relating in particular to a kind of family curve (Gamma Curve) of at least a color that can make in display fixes when just seeing, but when side is seen, the family curve of this color can be according to the mutual relationship of each color, and has not homonymy see characteristic display and display packing thereof.
Background technology
Liquid crystal material is developed its practicality at American Studies after being found by Europe, and the application technology in its physical property and various fields is in depth inquired into by Japan, and the new liquid crystal flat panel display from generation to generation of constantly development.At present, various liquid crystal technologies have been widely used on display, especially liquid crystal flat panel display (LCD), each manufacturer is by TN-LCD (Twisted Nematic-Liquid Crystal Display, the twisted nematic liquid crystals flat-panel screens) extends to STN-LCD (Super Twisted Nematic-Liquid Crystal Display, the super-twist nematic liquid crystal flat panel display), and more be extended to non-crystalline silicon tft-LCD (Thin Film Transistor LCD, the membrane transistor liquid crystal flat panel display), and scale increasing trend is arranged.
Generally speaking, the light transmittance that liquid crystal display is faced with to the liquid crystal display side-looking time is not identical, this be because, the incident light of different angles is in liquid crystal layer, the phasic difference value (Retardation) that produces is difference, therefore, when viewing angle not simultaneously, the suffered deviation coefficient of light is not identical, causes penetrance different yet.So different visual angles can cause the brightness of shown light different.And when different color light (for example red light, green light and blue light) when facing from side-looking each with different brightness ratio colour mixtures after, then can produce and face colo(u)r bias (color shift) phenomenon not identical with the shown color of side-looking.Generally, the degree of the colo(u)r bias that causes because of side-looking size is blue light＞green light＞red light.How reducing the colo(u)r bias when facing with the side-looking liquid crystal display, is one of problem of endeavouring of industry.
The settling mode that proposes at present is as follows:
1.Kalluri (United States Patent (USP) the 5th, 717, No. 474) propose pixel segmentation one-tenth is had several zones of different qualities, to satisfy the demonstration under the different visual angles situation.Shortcoming is one finish namely and can't adjust through making, and zones of different is respectively corresponding specific different angles of display, can descend to the display effect of raw frames.
2.Susumu (United States Patent (USP) the 5th, 847, No. 688) propose to utilize with the family curve of original signal according to two different visual angles situations, see through the respectively input in per two image times of different drivers (driver).Shortcoming is the flicker that the conversion meeting of picture in two image times causes picture, and it is shown for the picture of a special angle that synthetic picture only has the pixel (pixel) of half, can't actually solve the situation that many people view and admire simultaneously, and can cause the decline of picture resolution.
3.Paul Deng people's (United States Patent (USP) the 6th, 801, No. 220) propose to utilize the sub-pixel (subpixel) more than 2 * 2 to come display frame, utilize calculated value that display frame is originally adjusted, utilize bright dark pixel (pixel) ratio of different proportion to finish demonstration.Shortcoming is owing to utilize a plurality of pixels (pixel) to make display action, and considers take each pixel (pixel) as unit, so need to can solve problem in colo(u)r bias in greater than the situation of 170dpi at resolution.
Please refer to Fig. 8 A, 8B, Fig. 8 A is the synoptic diagram of the Pixel arrangement of an available liquid crystal display.Fig. 8 B is that the liquid crystal display of Fig. 8 A is with the result's of existing method demonstration synoptic diagram.。Comprise several pixels 711,712 etc. such as the color monitor 710 that is liquid crystal display, these pixels are matrix and arrange.Each pixel comprises two redness time pixel R, two green time pixel G and two blue sub-pixels B, and (stripe) formula is arranged into strips.Take pixel 711 as example, have the first red inferior pixel 7111, the second red inferior pixel 7112, the first green time pixel 7113, the second green time pixel 7114, the first blue sub-pixels 7115, reach the second blue sub-pixels 7116.
This kind color monitor is that a color commonly used time pixel is divided into two less inferior pixels, these two pixels are respectively to drive at colo(u)r bias is less and the angle of visibility deviation is less with great visual angle bright attitude display and dark attitude display, to synthesize a color GTG value, show a color, improve this color with great visual angle the colo(u)r bias that produces and improve its angle of visibility scope.See also Fig. 8 B, the first red inferior pixel 7111 is with the red display signal driver of a bright attitude; The second red inferior pixel 7112 is with the red display signal driver (the oblique line system expression among Fig. 8 B drives with dark attitude display) of a dark attitude.The redness of first red pixel 7111 and second red inferior pixel 7112 compound displays the first pixel 711 is with colo(u)r bias and the angle of visibility of the redness of improving the first pixel 711.Similarly, green and blue sub-pixels in the first pixel 711 drive demonstration in an identical manner, to improve colo(u)r bias and the angle of visibility of the first pixel 711 integral body.
In detail, different color light is when the same gray level value, and side-looking can be different from the normalization light transmittance of facing, thereby cause colo(u)r bias.When the GTG value near 0 or 255 the time, side-looking is less with the difference of the normalization light transmittance of facing, close to 0%.Therefore, for example, when the original GTG value of blue pixel is 128, can select a dark attitude display (being dark attitude GTG value) is 0, and a bright attitude display (being bright attitude GTG value) is 190, proofread and correct GTG value (comprising above-mentioned dark attitude GTG value and bright attitude GTG value) with this as one group, compound display and obtain visual experience such as original GTG value, and make this its side-looking of group correction GTG value also less with the difference of the normalization light transmittance of facing than the side-looking of original GTG value 128 with the difference of the normalization light transmittance of facing, and in the time of allowing again the user face liquid crystal display, can obtain the brightness identical with original GTG value, this group is proofreaied and correct the GTG value just can make liquid crystal display reduce in the colo(u)r bias of side-looking with positive apparent time.
In prior art, only do low color cast correction for two primary colors in the three primary colors because cost is often considered, that is only the obvious blueness of colour cast and green are done conversion, and do not change red original GTG value.Yet under the situation of only changing two primary colors, can cause side to see that colour mixture has problem, be that trichromatic side is seen family curve such as Fig. 9 A-9C, Fig. 9 D is that side is seen the superimposed figure of family curve, the red family curve that side is seen (Gamma Curve) is with blue and green family curve is not overlapping, to such an extent as to see that in side the visual angle can produce colour mixture during without the color of chroma incorrect and cause partially red phenomenon when demonstration.Therefore, be necessary to provide the color monitor of a kind of innovation and tool progressive, to address the above problem.
