[Previous technology] According to the conventional color filter device of the LCD, the R (red), G (green), and B (blue) sub-pixels are combined into pixels. This traditional color filter device has better color saturation. However, excessive color saturation will reduce the brightness of the liquid crystal display, so that the display effect of actual brightness cannot be achieved. Therefore, it is like the improvement scheme proposed by the patent publication No. 5 7 3 2 8 4 of the Republic of China, which is based on color filtering W (white) sub-pixels are added to the R, G, and β sub-pixels of the device (the arrangement is as shown in Figure β). This color data device uses the W (white) sub-pixels (that is, the brightness enhancer). Pixels) and its surrounding R, G, and B sub-pixels are mixed to increase the brightness of the displayed color. Such a liquid crystal display device further provides a calculation device that calculates digital output values Ro, Go, and Beta to drive the rG, R1, Gi, and Bi from the relative digital wheel values of the R, G, and B subpixels, respectively. Β sub-pixel; and-the digital value w is used to drive the _ (white) sub-pixel (brightness sub-pixel), and its towel R1: Gl ·· __: (_): (_: — relationship can be satisfied, Ri, Gi and Bi can be obtained from the input color image. However, the size of the w (white) sub-pixel of this LCD display is the same as that of the R, G, and B sub-pixels, which will make each pixel surface 1233504 The product is increased, reducing the resolution of the picture. In addition, using the digital value you drive the w (white) subpixel, and the digital value w is obtained as w = f (Ymin), Wf (Ymax, Ymin) ', where ^ Ymax * Ymin are the red subpixel and the green The digital inputs of the sub-pixel and the blue sub-pixel are only-maximum and-minimum. Because its calculation is too simple, and it does not fully consider the relationship between color saturation and brightness, it can easily increase the brightness of the display by the same%, and also reduce the overall color saturation and resolution. Therefore, although the aforementioned Japanese Patent No. 5 7 3 2 8 4 can increase the display brightness, it also reduces the resolution and color saturation of the display, so it still has room for improvement. [Summary of the Invention] The main object of the present invention is to solve the above-mentioned problem and provide a color data split with a brightening structure. By combining a blue subpixel and a white subpixel to form a composite brightening subpixel, and making it The width of the combination is the same as that of a single red or green sub-pixel, and the white sub-pixels are mixed with the red,,:, and blue sub-pixels to increase the brightness and maintain the display without increasing the width of the composite redundant sub-pixels. Resolution. 'In order to achieve the aforementioned purpose, the present day is a kind of color black device with a brightening structure.'

To improve this problem, increase the blue sub-pixels 1 The color saturation of 31 is reduced by the area of white sub-pixels 1 2 3; however, the redundancy is increased from 1 3 9 to 2 1 8 cd / m2 (candle / square meter), which increases 1235504 by 56%. As shown in FIG. 3 of Mingling Reading, the second embodiment of the present invention is a color filter device of the Mo s a c type arrangement, which is Mo s a. The color filter device of the type arrangement is such that the red sub-pixel 2 丄, the green sub-pixel 22, and the 1-color sub-pixel 23 are alternately set in each column with a smaller width (P 1 tch) (this embodiment is It is set to half the width.) Although the width of the red sub-pixel 23 is smaller, it is not set to the composite brightness-enhancing sub-pixel of the previous embodiment, and when the position of the blue sub-pixel 23 is rotated to a larger width Set the position, the visibility of the blue sub-pixel 2 3 is still set to half, and the white sub-pixel 2 4 is set in the reserved space, and the mouth [color sub-pixel 2 3 and white sub-pixel 2 4 are combined It becomes the composite brightness enhancement sub-pixel of the foregoing embodiment. After converting by the neighboring coordinates, obtain W 2 0 \ 299xR + .587xG + (hll4xB, then add the saturation saturation judgment formula to drive the white sub-pixels 24, and measure this example in all black, all red, When the daylight surface is completely green and blue, please refer to FIG. 5 for the structure of this embodiment (indicated by Qian Saic · b) and the traditional Mosai. The video output standard ntsc (National Television Standards c⑽miUee) decreased from 4 4 · 22% to 43 · 22%. The decrease is also the blue sub-pixel 2 3 which is less sensitive to human vision. To improve this problem, you can increase the color saturation of the blue sub-pixel 23 or reduce the area of the white sub-pixel 24; however, the measurement of brightness is increased from 1 3 5 to 1 8 5c: d / m2 (Candle / square meter Rule), which increased by 37%. 1233504 Following the above, the measurement results of the two previous embodiments of the present invention in CIE: coordinates (please refer to Figure 2 and Figure 4, the first embodiment is based on De e 1 The ta · b line indicates that the color filter k of the traditional Dee ta type arrangement is D e 1 ta · A line is indicated; the second embodiment is indicated by M osa 1 c · b line, and the color filter of the conventional M osa 丄 c type arrangement is indicated by M osaic · a line), which can make the contrast (full White shell degree / full black brightness) and brightness increase. In addition, the present invention does not increase the single pixel of the combination of red, green, and blue sub-pixels, so the resolution will not decrease.
