Description of the Invention: [Technical Field] The present invention relates to a method for displaying a facet, and {refers to a screen display method for outputting sub-pixel values of a color-emitting device. [Prior Art] With the advancement of technology, in recent years, most of the electronic devices have been light and small as the main appeal, and in the a _ _ 寻 々 々 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 The city (10) has an absolute advantage of L; the lit liquid crystal molecules themselves are not inconsistent, so the use of the moonlight board and the color light sheet makes the display a rich color image. Ding Wangxiong is known as a color filter. Each pixel is composed of R, ", and β. Therefore, when different strong products are produced, Feng Yi a - seeds like Xiaoqiang and the source of the sub-pixels The color mixing 2 allows the pixels to exhibit different colors and brightness. However, the color filter composed of the three-color structure has a narrow NT j and cannot satisfy the high-quality color display requirement. The method used is to use a four-color structure to form a color filter of the four-color structure disclosed in the color, for example, the four-pixel pixel of G, B, and c is used as a basic structure, and is matched with 浑= use, in order to enhance the NTSC gamut range and maintain white balance.: Figure:: Γ糸 t t 色 色 色 ' ' 其中 其中 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该When the c sub-pixels are equal in area, the color gamut can be expanded in the correct direction (indicated by the arrow in the figure), and the effect of 1352967 white balance can be obtained. The detailed reasons are as follows: R, G, B, C are known. The color mixture can be displayed in white, so the coffee "......................... ..............

When the ratio of the area of the sub-pixels and the sub-pixels is the same, the algorithm can calculate the color output value of the pixel by the algorithm of ^^峨^. The color gamut is expanded in the correct direction. According to the sub-pixel, the color of the peripheral color or the circumference of the chromaticity coordinate map can be selected. In order to balance the need for white balance, it is necessary to adjust the corresponding ones. However, the technical pixel areas disclosed in the above patents are not completely equal, and the color gamut range is extended for use in the figure. The provided algorithm is applied to the chromaticity coordinate map of the color filter device with unequal sub-pixel areas. In 6 1352967, 'assuming R, G, B, and f are earlier 々-. ^ The area ratio of sub-pixels is 3 : 2 : 3 : 2, It can be seen from « that the gamut range extends direction toward the test bell (fl value Shi, 13⁄4 «+» outside and the melon-known map of the color area of the 祀 祀 _ (the front head in the picture Show), its detailed reasons.

Linear expansion.

Implementation = Schematic. In the figure, the left picture is the structure diagram of the color filter device, and the figure is the left picture. In the present embodiment, the color filter device i enhances the color or the purpose of the surrounding color. Therefore, each pixel u of the color filter device i is composed of - 2 sub-pixels (1), a green sub-pixel (1), and - blue sub-pixel 113. The pixel 1H is composed of a mixed color sub-pixel ι 4 composed of two colors of two colors: and blue sub-pixels. In this example, in order to obtain a wider color gamut range, the green sub-1352967 pixels 112 are made of a green material having a chromaticity coordinate rather than the periphery (for example, 83% or more of green material), and the mixed color sub-image f Ϊ́4 is a yellow sub-pixel that is mixed with a red material and a green material. At the same time, in order to balance the effect of white balance, the area of each sub-pixel is adjusted accordingly. Therefore, the area of each pixel is not completely equal. As shown in FIG. 4, it is a flow chart of the screen display method of the present invention. Since the area of each pixel is not completely equal after adjustment, in order to make the color gamut range expand in the correct direction, the production process of the face display method of the present invention 2 The method includes the following steps: First, when an image signal consisting of red: 唬, green signal, and blue signal is input to the frequency 1 ', the process proceeds to step 22, and the color 遽 is calculated by using a computing device. The color sub-pixel output value (R.), the green sub-pixel output value (G): and the blue sub-pixel output value (8), wherein the calculation device is mounted This is the color of the tiger (R.), the green signal value (6), and the blue signal value (6) multiplied by the score: as the red, green, and blue sub-pixels of the input / exchange 5 'R., G , in the same manner as Ri, Gi, and Bl, in step 23, it is determined whether the value of any of the two sub-pixels constituting the mixed color sub-pixel is ?, in this embodiment, the color-mixing sub-pixel is red and , : The color sub-pixel formed by the color. When R. or G. is 〇, step 24 'set the mixed color sub-pixel output value (8) to 〇, otherwise, when two; = 〇, then proceed to step 25 ' According to the two sub-pixels constituting the color-mixing sub-pixels: the surface: the ratio of the set-weight value is calculated by the weight value, and the value of the mixed-color sub-pixel is calculated by the weight value. In this embodiment, the two sub-pixels are green. The calculation method of step 25 is as follows: For convenience of explanation, it is assumed here that the area ratio of each sub-pixel of the color filter device is 1352967 · S., a: Ya=2:3:3:2' That is, (4) (10) 3:2, where the 7-color sub-pixel (7) is the color of the red sub-pixel (8) and the green sub-image symplectic (6), so the yellow sub-pixel is In the two unit areas, each of the green areas is one unit area, that is, Ra: Ga = (9)) · (3 + ι): 3:4: = the pixel penetration area is proportional to the brightness, so the value is also 3:4, so in order to achieve the white balance, the area ratio, the machine: r壬 &- the text according to the pixel area of the WG due to the output value of the towel rm in this example (S.). The ratio _ Α Λ . 'So if the ratio of the area penetration half is to be 4. 3 ' then s 〇 should be R. * 4 / (4 + 3) + G. * 3 / (4 + 3 The algorithm representation also shows that the method of the present invention can be performed according to the following (1) R, G, B. 2) s. The calculation method (2-1) constitutes the output value of any one of the two sub-pixels (P|, p2) of the color-mixing sub-pixel (p "p24", then s〇=〇; wi) when forming the color mixture The rounds of the two sub-pixels (p|, h) of the sub-pixel are out. ,? 2. ) are not 0, and? |,? When the area ratio of 2 is Ai : A2, then s〇 = p.o* a2/( a, + A2) + p2o* Al/( A) + A〇 10
