Description of the Invention: [Technical Field] The present invention relates to an image processing method and a display device, and is related to: a species capable of achieving high brightness, Good image sharpness image processing method and display device. [Prior Art] In the development of liquid crystal displays, high brightness 1 is becoming more and more important. In order to obtain high brightness, the driving current can be increased to provide a high-brightness surface light source for the moonlight module, or to increase the aperture ratio of the pixel during the design of the element. However, as far as the former is concerned, it will lead to a large increase in system power consumption; in the latter case, the increase in the aperture ratio of the halogen has its design limit, and it is easy to cause circuit parasitics and variations in the process, etc., in order to improve the above disadvantages, A liquid crystal display composed of four sub-halogens is known, that is, a white sub-pixel is added to the conventional RGB layout to improve the average redundancy of the RGB W-type liquid crystal display. However, adding a white sub-halogen before moving the area of each pixel will reduce the area of each sub-halogen to 3/4, which will reduce the aperture ratio, especially Add multiple scan lines and data lines to drive the new white sub-pixels. Furthermore, the addition of a white sub-composite is carried out without changing the area of the sub-pixel, so that the aperture ratio can be maintained. However, since the area of each pixel is large and the display area is fixed, the number of elements that can be accommodated is reduced to cause a decrease in resolution. y, in recent years, a liquid crystal display with improved stripe matching 200945256 WP9608-C400-0681 26800twf.doc/p Modulated Stripe RGBW pixel layout has been developed. Using the algorithm of sub-satellite sharing, it not only solves the problem of decreased aperture ratio, increased scan line and data line, but also shows the resolution of the original image. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a liquid crystal display device having a modified stripe RGBW pixel layout. Referring to the figure, the liquid crystal display device 1 displays an image by using the shared $ of the selected pixel unit 110 and the surrounding white sub-small. The sub-pixels of the white sub-pixels are composed of the original image data of the package: two bases, colors, and images (10) (RGB), and the three basic color seals are used to properly correct the three basic colors. Expected in the entity, sub-pixel data (w). When;;=: like;:,) The most two and there are - the situation of production B.

Brightness and good sharpness of the image. In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following detailed description will be given in conjunction with the accompanying drawings, which are described in detail below. The alizarin extraction step and the sub-purine arrangement calculation do not add additional data lines and scan lines, === image, solve the color problem. The following; = color case is described, however, the present invention ~ Like the treatment method, it is suitable for the case of any wrist (four) and the text.

The color mixing problem generated in A (RG blends into yellow), that is, it can enhance the contrast between black and white and increase the sharpness of the image or text. Similarly, as shown on the right side of Figure 3, the original image data P3 And ρ4 performs black and white phase judgment, and further, RGBW (ie, region B) in the plurality of sub-small elements BWRGBW can be forced to form a complete white area. Detailed steps of the image processing method of the preferred embodiment of the present invention will be described in detail below. FIG. 4 is a schematic diagram of an image processing method according to a preferred embodiment of the present invention. Referring to FIG. 4, the image processing method includes the following steps. First, a mathematical operation is performed on an original image tributary PI, P2 (or p3, p4) of an Nth element and a (N+1)th element, to obtain a solid color adjacent judgment parameter Check. (shown in FIG. 5), wherein the original = image data PI, P2 (or P3, P4) includes three basic hue sub-memory data RGB, and in one embodiment, N may be an odd number. Then, at least one of the enhanced chromatographic data W1, W2' is calculated according to the original image data Pb (or p3, P4) and the original image data ρι, p2 (or p3, p4) is converted into a polychromatic image. The data M1, M2 (or M3, M4), the polychromatic image data] VQ, M2 (or M3, M4) includes the three basic color ray element data RGB and the enhanced color 昼 资料 data w. Then, according to the solid color neighbor determination parameter Check, the polychromatic image data μB M2 (or M3, Μ4) is re-arranged in the second and fourth (Ν+1) pixels. The implementation of each step is explained below. In the step of obtaining the solid color adjacent judgment parameter Check, it is determined by the two 12 200945256 WP9608-C400-0681 26800 twf.doc/p elements as a group. FIG. 5 is a schematic diagram of determining whether two adjacent pixels are adjacent to each other in black and white according to a preferred embodiment of the present invention. Referring to FIG. 5, a mathematical operation is performed through three sub-halogen data of rl, gl, and bl in the Nth halogen, and r2, g2, and b2 in the (N+1)th halogen, to obtain a solid color adjacent. The parameter Check is judged, and it is determined whether the Nth pixel and the (N+1)th pixel are adjacent to each other in black and white. As shown on the left side of Figure 5, assuming that the resolution of the original image is (240 X 320 X RGB), the original image data can be grouped into a total of 320 ® groups such as G0~G319, and each group contains 240 pixels (240). Pixels), each element has 3 sub-pixels (RGB). In particular, the above mathematical operation is performed in a group of two elements, and the calculation result shown in the right side of Fig. 5 can be obtained, and the process of the mathematical operation is displayed above the arrow. In more detail, one embodiment of this mathematical operation is as follows. First, the N-th element and the (N+1)th pixel corresponding to the three basic color-phase sub-genogen data are subtracted to obtain three values. That is, as shown above the arrow in FIG. 5, the three sub-halogen data of rl, gl, and bl in the Nth halogen, and r2, g2, and b2 in the (N+1) halogen are mutually Subtracting, three values (r2-rl), (g2-gl), (b2-bl) are obtained. Then, the three values (r2-rl), (g2-gl), and (b2-bl) are taken as absolute values, as shown in Figure B, r = abs ( r2-r 1 ), g = abs (g2 -g 1 ), b = abs ( b2-bl). Then, the three values r, g, and b after the absolute value are added to obtain the solid color adjacent judgment parameter Check (that is, Check = r + g + b). In particular, the solid color neighbor determination parameter Check can be stored in one or more temporary memory spaces as shown on the right side of Figure 5, 200945256 WP9608-C400-0681 26800twf.doc/p. In general, the grayscale value representing black is 〇, and the grayscale value representing white is 255. Therefore, when the value of the solid color adjacent judgment parameter Check is 765, it represents the Nth element and the number (N). +1) The elements are black and white adjacent to each other' At this time, an indication signal of "1" is given. On the other hand, when the value of the solid color adjacent judgment parameter Check is not 765, it means that there is no black and white adjacent feature between the nth pixel and the (N+1)th pixel. 〇,, ❿ The indication signal. In the above embodiment, the three basic color sub-pixel data are respectively subjected to subtraction, absolute value, addition and other mathematical operations, and the present invention is not limited to the above mathematical operation, and any other phase can be determined. The neighboring pixels are mathematical operations in black and white. In the step of converting the original image data PI, P2 into the polychromatic image data %^M2, a preferred embodiment is as follows. First, at least one color-enhancing pixel data is calculated based on the original picture data Pi, P2, for example, at least two of the three basic color-phase data are calculated. If the data is not the same, the above three basic color photonic material data can be red (R), green (G) and blue (B) sub-tendin image data, taking all red (r), green (G) and The blue (B) sub-pixel image is calculated by three operations, and white (W) color enhanced sub-pixel image data can be obtained. ★ In addition, if you take the green (G) and blue (B) sub-small image data ^ two calculations, you can get the yellow (Y) color enhanced sub-pixel image. That is, the above-mentioned color-enhanced scorpion image data is, for example, white (W), color: $ (Y), magenta or cyan scorpion image; Tian Ran, %-toner image data is not limited to the above Four colors, 14 200945256 wry〇ue-0400-0681 26800twf.doc/p can also be other suitable colors. As a result, as shown in Fig. 4, multi-color image data M1, M2 including the three basic color sub-small material data RGB and the color enhanced sub-small material W (or Y, Μ, G') can be obtained. In addition, the Nth element includes the three sub-smectins, the (Ν+ι) pixels include three sub-pixels, and the layout of the sub-tendines is selected from the group consisting of: improved striped with dirty W (five) dice Alizarin, improved stripe with RGBY four-color sub-salmon, improved strip multi-text with RGBG, four-color sub-salmon, 改良 improved stripe with RGBM four-color sub-small. It is noted that the different reference tf signals 'output according to the solid color adjacent judgment parameter Check can determine how to distribute the multi-color image data M1, M2 shown in Fig. 4. Figure 6 is an indication of the output of the solid color adjacent judgment parameter, T, the indication signal %, ', the layout of the sub-element is a complete white area ^ ^ Refer to Figure 6 'When the solid color adjacent judgment parameter Check indication The original image data ρι, p2 (or p3, p4) of the N alizarins and the (n+i) alizarins are adjacent to each other.

Similarly, the multi-color image data M3 and M4 on the right side of Fig. 7 can also be arranged in the same manner as the sub-pixel arrangement, and will not be described herein. The above-mentioned image processing method can achieve the following advantages: no additional data lines, scan line design, display brightness enhancement, optimization _ text sharpness, and resolution of text color mixing. It is worth mentioning that, in view of the diversity of text presentation, such as color background black and white characters, black and white background color words, etc., the algorithms that can be implemented depend on the design of the system, and are not limited to the above-mentioned black and white adjacent Illustrated embodiment. FIG. 8 is a schematic diagram of another image processing method according to a preferred embodiment of the present invention. Referring to FIG. 8, the solid color neighboring judgment parameter between the Nth pixel and the (N+1)th pixel is X, and the value of X can be changed to change the color background' to apply to the background of any color. The situation of the text. When the indication signal "1" is output according to the 17 200945256 WP9608-C400-0681 26800twf.doc/p solid color adjacent determination parameter X, forced color distribution is performed; if the parameter X is output according to the solid color adjacent determination parameter X , then min() sharing (also available with average sharing). As for the detailed steps of the color distribution as described above in Fig. 6, the min() sharing has been described above with reference to Fig. 7, and will not be described herein. Fig. 9A is a schematic diagram of a character obtained by arranging a pixel arrangement in a stripe shape. 9B to FIG. 9C are textual representations in which the mean value sharing and the minimum value are respectively shared in the improved tiling layout of the four-color sub-crystal. Fig. 9D is a schematic diagram showing the text obtained by using the image processing method of the present invention in the improved tiling layout of the four-color sub-halogen. Comparing Fig. 9A and Fig. 9B to Fig. 9D, it is understood that the overall brightness of the characters displayed by the pixel layout having the improved stripe type of the four-color sub-tendin is significantly brighter. When the average value sharing is used, comparing the regions C2, C3, and C4 of Fig. 9B with the regions E2, E3, and E4 of Fig. 9D, the text of Fig. 9B is more ambiguous and not sharp enough. In particular, comparing the region C1 of Fig. 9B with the region E1 of Fig. 9D, it is understood that there is still a color mixture phenomenon (a sub-element indicating gray) in the region C1 of Fig. 9B. In addition, when the minimum value sharing is used, comparing the area D1 of FIG. 9C and the area E1 of FIG. 9D, although the text of FIG. 9C is sharp, there is still a color mixing phenomenon in the area D1 (for example, RG is mixed into yellow). However, the area E1 in Fig. 9D is composed of four sub-units of RGBW, and is forcibly displayed as a white area, so that the color mixing problem does not occur, and the black-and-white contrast can be increased.
