-TM: u ; W3395PA IX. Description of the Invention: [Technical Field] The present invention relates to a color filter structure and a display panel using the same, and a display method thereof, and particularly to an improved color Saturation color filter structure and display panel using the same and display method thereof. [Prior Art]

Liquid crystal display devices have become increasingly popular due to their thinness and lightness. Basically, liquid crystal display devices are often used in combination with color filters having substantially three colors such as red, green, and blue. Since the user's demand for color saturation of the liquid crystal display device is increased, a color filter that adds more of the fourth color is currently produced. This type of liquid crystal display device is mainly a color filter with four colors to enhance the color saturation of the liquid crystal display device. However, the aforementioned liquid crystal display device tends to have a problem of white balance. Please refer to Table 1, which is a list of white display CIE chromaticity coordinate values for conventional RGBY and RGBC type liquid crystal display devices. Table 1 N White display CIE chromaticity coordinate value NTSC ratio (%) X y RGBY type 0.3462 0.3616 75.44 RGBC type 0.2617 0.2925 75.63

IW3395PA 200821635 In general, the white display CIE chromaticity coordinate system is (0·33, 0·33). In other words, the closer the white display CIE chromaticity coordinates are to the (〇·33, 0·33) liquid crystal display device, the better the white balance effect. However, as shown in Table 1, the white display cm chromaticity coordinates (0·3462, 0·3616) of the RGB Υ type liquid crystal display device are compared with the white display cm chromaticity coordinates, regardless of the X chromaticity coordinate value. Or the y chromaticity coordinate value has a certain difference. The white display CIE chromaticity coordinates (0·2617, 0·2925) of the RGBC type liquid crystal display device are also the same as the white display CIE chromaticity coordinates. Therefore, as can be seen from the first table, both the RGBY type and the liquid crystal display device have problems of white balance. As for the NTSC ratio in Table 1, the ratio of the color reproduction range of the liquid crystal display device to the standard of the television system established by the National Televisi〇n System Committee (NTSC). The television system standards established by NTSC are defined by the chromaticity coordinates (〇·67, 〇·33), (〇 2ι, 〇·71), and (0·14,0·08). If the NTSC ratio is higher, the color reproduction range of the LCD display device is closer to that of NTSc. As shown in Table 1, the RGBY^ liquid crystal display device iNTSc ratio is 75.44%, and the RGBC type liquid crystal display device NTSC! ratio is 75 63 /〇: from the above NTSC ratio, two types of liquid crystal display devices are known. The range of color reproduction is not as good as that of NTSC's television standards. Furthermore, since the RGBY type and RGBC type liquid crystal display devices have increased the number of secondary elements of the RGB35 liquid display device, it is necessary to add and reconfigure additional driving elements (such as drive lines and transistors). ). 200821635

Compared with the performance of the RGBC type reading device mentioned in the first table, the display of the color filter structure (10) has a better white balance characteristic and the color reproduction range is closer. The scope of the television system standard established by Finance. In addition, if the hue angle in the chromaticity coordinate system (CIE L*u*V*) established in 1976 is used to define the color characteristics of the color layer G1 and the color G2 of the filter layer, The hue angle of one color G1 ranges from 140 degrees to 220 degrees, and the hue angle of the second color G2 ranges from 90 degrees to 140 degrees. The hue angle is obtained by converting the coordinate value X and the coordinate value y of the first color G1 and the second color G2 corresponding to the CIE chromaticity coordinate map of Fig. 3 by coordinate conversion. When the display panel 500 is driven (as shown in Fig. 1), a plurality of pixel center filter regions are defined according to the displayed surface. These halogen center filter zones are each composed of three adjacent sub-halogen filter layers, as exemplified below.

The pixel center filter region 130 is only an example of this embodiment. According to other peripheral pixel filtering regions, the color filter structure 1 〇 0 may have other pixel center filter regions composed of three adjacent sub-tenk filter layers. Of course, the color filter structure 1〇〇 can also have other selective filter regions located around the filter center of the pixel. The color filter structure 100 of this embodiment has, for example, a cell filter 10 region 140. The halogen filter region 140 is composed of a pixel center filter region 130 and selective filter regions 130r, 1301, 130t, and 130b. Of course, the halogen filter zone can include any number of selected filter zones around the halogen center filter zone 130 and the surrounding. For example, please refer to FIG. 5, which illustrates a schematic view of the color filter structure of FIG. 4 having another pixel filter region. As shown in Fig. 5, the halogen filter region 440 of the color filter structure 100 includes only the halogen center filter region 130 and the selective filter region 〇13〇Γ located on the right side of the pixel center filter region 13〇.

~mmm · TW3395PA These rows include a plurality of filter layers of the same width of four colors that are repeatedly arranged. Each of the filter layers corresponds to a single pixel setting, and the display color of the secondary pixels is the color of the corresponding filter layer. Therefore, the secondary steroids are red quercetin, blue quercetin, first color quercetin and second color quinone. Color filter structure 100 (shown in Figure 5) has a halogen filter region 440. The halogen filter region 440 includes a halogen center filter region 130 and a selection filter region 130r. Next, as shown in Fig. 6, in the step scale 220, an image data is supplied to the display device. Please refer to Figure 7 for a schematic diagram of the image data. The image data includes the three-color data value Ay of red scorpion, blue scorpion and green scorpion (in the present embodiment, i, j=l~4 to correspond to the structure shown in FIG. 5) Raij, Gaij and Baij are the gray scale values of the red sub-halogen, the green sub-halogen and the blue sub-halogen of the three-color data value Aij. For example, as shown in Fig. 7, the first three-color data value A31 of the third column includes the gray scale values Ra31, Ga31, and Ba3l of the red sub-halogen, the green sub-halogen, and the blue sub-halogen. As shown in FIG. 6, in step 230, the gray level values Raij, Gaij of the red color and the green sub-pixel of the three-color data value Ay are calculated to convert the three-color data value Ai:j into four colors. Data value A, 』. Please refer to FIG. 8 , which is a schematic diagram showing the conversion of the three color data values of FIG. 7 into four color data values. The converted four-color data value A'ij includes the gray-order values of the red sub-album, the green sub-pixel, the color-adjusting element, and the second color, which are Rdij, Gdij, Bdij, and G2dij, respectively. For example, the three-color data value A31 of Fig. 7 is converted as shown by the first four-color data value A, 31 in the third column of Fig. 8, which is 200821635.

i. iW3395PA includes red sub-pixels, green sub-albumin, blue sub-halogen and gray-scale values of the second color sub-dinals Rd3i, Gd31, Bd31 and G2d31. Step 230 will be further described to calculate the gray scale value Rdij of the red color sub-form of the three-color data value Aij and the gray scale value Gdij of the green sub-tendin to convert the three-color data value into the four-color data value A'ij. In step 230, the three-color data value A! can be converted into a four-color data value A' by using two methods as shown in Figs. 9A and 9B. . Please refer to FIG. 9A, which shows a flow chart of step 230 of FIG. 6. ❿ First, in step 231a, the gray level value Raij of the red sub-halogen of the three-color data value, the gray level value 3_ of the blue sub-halogen, and the gray-scale value Gaij of the green sub-tendin are retained. In other words, Rdij = Raij, Gdij = Gaij and Bdij = Baij. For example, in Figures 7~8, ' Rd31=Ra31, Gd31 = Ga31 and . In step 231b, the gray scale value Raij of the red color of the three-color data value and the gray scale value Gaij of the green sub-pixel are compared, and the smaller gray scale value is taken as the second color second. The gray scale value of the prime is G2dij. In other words, G2dij=min(Raij, Gaij). This is a method of converting the three-color data value Ay to the four-color data value A. Referring to Figure 9B, another flow diagram of step 230 of Figure 6 is shown. This flowchart is another method of converting the three-color data value Aij to the four-color data value A. First, in step 232a, the gray scale value Raij of the red sub-pixel of the three-color data value Ay, the gray scale value Baij of the blue sub-halogen, and the gray scale value Gay of the green sub-halogen are retained. In other words, Rdj = Raij, Gdij = Gaij and BdirBaij. Next, in step 232b, a weight value Sy is calculated, where Sij = Clij / (Clij + C2ij). The Clij and C2ij systems are dichromatic lean values respectively. Ay 13 200821635

—* TW3395PA The gray-order value Gaij of the green sub-halogen and the gray-scale value Raij of the red sub-pixel. That is to say 'Clij=Gaij and C2ij=Raij. Then, in step 232c, the gray scale value Clij of the green sub-tendin is multiplied by the weight value Sij as the gray scale value G2dij of the second color sub-halogen. It is expressed in mathematical form as GadfSij xClij. Step 230 can be completed by using one of the two methods of FIG. 9A and FIG. 9B to convert the three-color data value Aij of FIG. 7 into the four-color data value A′ as shown in FIG. 8 . 』. Next, please refer to FIG. 10 and FIG. 11 , FIG. 10 is a schematic diagram showing the values of the three color data in the third column of FIG. 7 , and FIG. 11 is the fourth after the conversion of the three color data values in FIG. 10 . Schematic diagram of color data values. The display method of the present embodiment will be exemplified only by the three-color data value A3j in the third column of Fig. 7 and the converted four-color data value A'3j. As shown in Figure 10, the third color data value in the third column of Figure 7 includes 3) the gray level value Ra3j of the red sub-halogen, the gray-scale value of the blue sub-halogen, and the green sub-segment Gray scale value Ga3j. After the above step 230 of Fig. 6, the four-color data value A'3j as shown in Fig. 11 can be obtained. Any four-color asset value A'3j includes a first data area and a second data area. The four-color data value 八 includes, for example, the first data areas D11, D12, D13, and D14 and the second data areas D21, D22, D23, and D24. The first data areas D11, D12, D13 and D14 are lean regions consisting of three adjacent gray scale values of the sub-halogen. The gray scale value of the second tributary area is the gray scale value not included in the first tributary area. Taking the four-color data value A, 31 as an example, the first data area D11 includes the gray level value Rd31 of the red sub-halogen, the gray-scale value Gd31 of the green sub-tendin, and the gray-scale value Bd31 of the blue sub-pixel. The second data area D21 is a package 14 200821635

—mmm * TW3395PA includes the grayscale value G2d3i of the second color. And the four-color data value A,? For example, the first data area D12 includes a gray level value Rd32 of a red sub-tendin, a gray level value Gd32 of a green sub-pixel, and a gray level value G2d32 of a second color sub-halogen, and the second data area D22 includes The gray level value of the blue sub-pixel Bd32 0 Next, as shown in FIGS. 6 and 11 , in step 240, the first value is taken out from the first data areas DH, D12, D13, and D14, respectively. The first value includes the corresponding correspondences of the first data areas D11, D12, D13, and D14. • The gray scale values of the three adjacent subsegments in the third column of Fig. 5 are. Taking the first data area D12 corresponding to the pixel center filter area 130 of FIG. 5 as an example, the first values are Rd32, Gd32, and G2d32. Then, as shown in Figs. 6 and 11, in step 250, the second values are respectively taken out from the second data areas D21, D22, D23 and D24. Taking the pixel filter region 440 of the pixel center filter region 130 in the fifth embodiment as an example, since the pixel center filter region 130 does not include the blue color and the halogen, the second value is Bd32. In other words, in step 240 and step 250, when the selected pixel center filter region includes red sputum, blue scorpion and green scorpion, the first value is the red of the first data region. The gray scale value of the halogen, the blue sub-halogen and the green sub-halogen, and the second value is the gray-scale value of the second color of the second data region. The first value is the first data area when the selected pixel center filter region includes any of the red sub-pixels, the blue sub-halogen and the green sub-halogen, and the second color sub-pixel. The gray value of the two sub-halogens in the medium red sputum, blue sputum and green sub-pixels and the 15th

20082L635rW3395PA The gray level value of the second color subsequence, and the second value is the gray level value of the secondary element not included in the foregoing. Then, as shown in FIG. 6, in step 260, the first value and the second value are calculated to obtain the actual grayscale values Rpij, GpU, Bpij, and G2pij of the second pixel of the first data region when driving. . In the embodiment, the second value obtained by the second data area is combined with the first value of the first data area of the other element filter area on the right side of the pixel filter area. The following examples are given. • Refer to Figure 12, which shows a schematic diagram of the combination of the first value and the second value of the four-color data value taken in Figure 11. As indicated by the arrow in Fig. 12, the second values of G2d31, Bd32 and Gd33 are combined with the first values G2d32, Bd33 and Gd34, respectively. Taking the first data area D12 as an example, since the second value G2d31 of the second data area D21 is shared to the first data area D12, the G2d32 of the first value will be adjusted. The original grayscale values Rd32 and Gd32 do not need to be combined with other second values, so the new grayscale value Rn32=Rd32 and Gn32=Gd32', where 〇2η32 can be • the average or minimum of G2d32 and G2d31. As for the Bd32 system, the gray level value of the secondary element of the second data area D22, so 匕32 is also the second value. Since it is shared to the right, Bd32 is combined with Bd33 which is the first value of the first data area D13. Similarly, the new grayscale value Bn33 can also be the average or minimum of Bd32 and Bd33. The steps of the display method of this section are exemplified by the data corresponding to the pixel filter area 440 in the third column of Fig. 5, and the manner in which other data is calculated is also described in this section. In this embodiment, due to the display method and the structure of the color filter 200821635

As shown in Figure 13, the horizontal row is composed of the calculated new grayscale values. The information in the blank space in this column • is the position of the second data area in Figure 12. Since the second value taken out from the second data region of any of the halogen filter regions is combined with the first value of the first data region of the other halogen filter region, no new gray scale is obtained in this portion. value. Therefore, in the course above the 13th figure, the second data area is indicated by a blank. The horizontal row below is composed of the rearranged grayscale values, and the grayscale values of the horizontal rows are the actual grayscale values Rpy, Gpij, Bpij and G2pij used to drive the secondary pixels. The arrangement of the actual gray scale values Rpij·, Gpij, Bpij, and φ G2py corresponds to the arrangement of the light-passing layers of the color filter structure 100 (as shown in Fig. 5).
