Abstract
The invention is a color filtering device with brightening structure, composed of many pixels, each of which includes a red subpixel, a green subpixel and a compound brightening subpixel, where the compound brightening subpixel is composed of a blue subpixel and a white one, and the width of the compound brightening subpixel is the same as that of the red or white subpixel. By the compound brightening subpixel, the same width and the mixing of white subpixel with red, green and blue subpixels, it increases the brightness and maintains the display resolution without increasing the width of the compound brightening subpixel.
Description
Technical field
The present invention is the color filter device of relevant a kind of tool brightening structure, refers to that especially a kind of color filter device is combined into compound blast sub-pixel with blue subpixels and white sub-pixels, to improve the color filter device of display brightness.
Background technology
The color filter device of conventional liquid crystal is to become pixel by R (red), G (green), B (indigo plant) sub-pixel combinations, the traditional colored filter device of this kind has preferable color saturation, but excessive color saturation can make the briliancy of LCD reduce, and so promptly can't reach the display effect of intrinsic brilliance.
So, improvement scheme just like No. 573284 patent announcement case proposition in Taiwan, it is to add a W (in vain) sub-pixel (its arrangement mode as shown in Figure 5) outside R, G, the B sub-pixel in color filter device, this kind color filter device is by this W (in vain) sub-pixel (being brightness enhancer pixel) and its R, G, B sub-pixel colour mixture all around, and the color briliancy of demonstration is promoted.This kind liquid crystal indicator provides and calculates digital output value Ro, Go and Bo more by a calculation element, in order to drive this R, G, B sub-pixel respectively from relative digital input value Ri, the Gi of R, G, B sub-pixel and Bi; And utilize a digital value W, to drive W (in vain) sub-pixel (brightness enhancer pixel), wherein Ri: Gi: Bi=(Ro+W): (Go+W): a relation (Bo+W) can satisfy, and Ri, Gi and Bi can obtain from the input color image.Yet the width (Pitch) of the W of this kind liquid crystal indicator (in vain) sub-pixel size and R, G, B sub-pixel are identical, and it will make each elemental area increasing, and has reduced the resolution of picture.In addition, utilize digital value W to drive W (in vain) sub-pixel, and obtaining of digital value W is to be W=f (Ymin); (Ymax, Ymin), wherein Ymax and Ymin are respectively these digital only a maximal value and minimum value imported of this red sub-pixel, this green sub-pixels and this blue subpixels to W=f.Because its computing is too simple, and does not have the complete relation of considering color saturation and brightness, when it easily makes the brightness of demonstration promote, whole color saturation and resolution are reduced.
Though, the resolution of demonstration and color saturation are reduced, so it still has the space of improvement so No. 573284 patent announcement case in aforesaid Taiwan can improve display brightness.
Summary of the invention
Fundamental purpose of the present invention, be to solve the above problems and a kind of color filter device of tool brightening structure is provided, by be combined into compound blast sub-pixel with blue subpixels and white sub-pixels, and make the width of its combination identical with the width of single redness or green sub-pixels, and by white sub-pixels and redness, green and blue subpixels colour mixture, with raising brightness, and, keep the resolution of demonstration not increase compound blast sub pixel width
For reaching aforesaid purpose, the color filter device of a kind of tool brightening structure of the present invention, it forms color filter device by most pixels, and respectively this pixel is to comprise a red sub-pixel, a green sub-pixels and a compound blast sub-pixel;
It is characterized in that: this compound blast sub-pixel is made up of a blue subpixels and a white sub-pixels, and red sub-pixel or the green sub-pixels with single is identical respectively with width size that white sub-pixels is formed for this blue subpixels.

See also Fig. 1 to Fig. 4, reach table 1, be the selected example structure of the present invention shown in Fig. 1 to Fig. 4, this only for the usefulness of explanation, is not subjected to the restriction of this kind structure in patented claim.Table 1 is that first and second embodiment of the present invention is in cie color and video signal outputting standard NTSC (National Television StandardsCommittee) comparison sheet (being attached to the back in the instructions).
The color filter device of the tool brightening structure of present embodiment, it forms color filter device by most pixels 10, wherein, respectively this pixel 10 is to comprise a red sub-pixel 11, green sub-pixels 12 and a compound blast sub-pixel 13, this compound blast sub-pixel 13 is made up of a blue subpixels 131 and a white sub-pixels 132, and red sub-pixel 11 or the green sub-pixels 12 with single is identical respectively for width (pitch) size that this blue subpixels 131 and white sub-pixels 132 are formed.Wherein, this white sub-pixels 132 is by an independently directly driving of channel (channel); The present invention is the digital output value W that calculate to drive this white sub-pixels 132 by a calculation element (not shown), and digital output value can be by formula:
W＝W
1R+W
2G+W
3B；
W
1+ W
2+ W
3=1; And
0＜W
1＜1；
0＜W
2＜1；
0＜W
3＜1；
And be to increase color saturation to add a judgement formula, as follows:
1. equal the Min value when R equals Max value, G, B equals Min value, then W
1Equal 1, W
2Equal 0, W
3Equal 0.
2. equal the Min value when G equals Max value, R, B equals Min value, then W
