提供的液晶面板之各色彩亮度(即紅、綠、藍等三原色的色 彩亮度，也就是一般所謂的R、G、B色彩亮度)不盡相同， 因此不同供應商提供的液晶面板所呈現出來的晝面，往往 會因為二原色的亮度規格相異而使得其色彩品質也跟著不 同。 如此一來，便對液晶顯示器(display)的製造商造成了 極大的困擾，其原因在於：顯示器製造商往往基於商業上 的考量而使用相同的控制主機板來搭配不同供應商的液晶 面板，然而這麼做卻也使得顯示器色彩品質的好壞，也往 _ 往取決於液晶面板上，進而導致所製造出來的顯示器之色 彩品質良筹不齊。 舉例來說，一般對於液晶面板而言，其所顯示之晝面 的色調疋由二原色的色彩免度依照比例而決定，而此比例 理想上應該要呈現出一個理想亮度比，但是大部分的液晶 面板卻都無法提供至這樣的比例。因而在目前所有供應商 所提供之液晶面板當中，有的液晶面板之藍色色彩亮度比 例值偏低，因此往往造成當晝面需要呈現出天空的顏色 5 200825392 IPD060593TW 22408twf.doc/n 時，此種液晶面板所呈現出來的天空顏色就偏白些，然而 有的液晶面板之藍色色彩亮度比例值卻偏高，因此往往造 成當晝面需要呈現出天空的顏色時，此種液晶面板所呈現 出來的天空顏色就偏藍些。 因此，如何將不同供應商提供的液晶面板之三原色色 彩焭度調校至同一理想亮度比，使不同薇牌的液晶面板之 色彩品質能夠趨於一致，便是所有液晶顯示器製造商必須 努力去突破的重要課題。再者，對於顯示器的使用者來說， 晝面品質的好壞常常取決於紅、綠和藍等三原色相混色而 產生的色彩，這個因素往往會決定使用者的購買意願，而 對於製造電腦或是液晶電視的廠商來說，這個因素甚至是 決疋疋否導入弟二供應商(second source)的重要因素。 【發明内容】

本發明由於透過測量液晶面板的一顯示晝面中，每一 顏色的色彩亮度比例值是否有任一個不在對應之理想亮度 比例值的預設範圍内。接著，當上述色彩亮度比例值中至 少有任一不在對應之理想亮度比例值的預設範圍内時，則 將每一色彩亮度比例值各自乘上對應的校正係數，以獲得 表新之色彩亮度比例值，進而使得上述各更新後的色彩亮 度比例值呈現出理想亮度比，而此理想亮度比就是上述各

224〇gtwf.doc/n (步驟120) ’其中上述顏色所對應之理想亮度比例值呈現理 想冗度比。接者，當上述色彩亮度比例值中沒有一個不在 對應之理想亮度比例值的預設範圍内時，就直接依據色彩 亮度比例值來顯示畫面（步驟16〇)。然而當上述色彩亮度比 例值中至少有任一不在對應之理想亮度比例值的預設範圍 内時，則將每一色彩亮度比例值各自乘上對應的校正係 數，以獲得最新之色彩亮度比例值(步驟13〇)。 然後’繼續判斷最新之色彩亮度比例值是否呈現理想 亮度比(步驟140)。當最新之色彩亮度比例值無法呈現理想 免度比時，就繼續修正上述色彩亮度比例值（即回到步驟 130)。當最新之色彩亮度比例值呈現理想亮度比時，則將 最新之色彩亮度比例值燒錄至液晶面板的基本輸入輸出系 統晶片（步驟150)。最後，使得液晶面板能依據最新之色彩 亮度比例值呈現出顯示晝面(步驟160)，就結束了此校正過 程(步驟170)。 為了使說明更淺顯易懂，以下先假設紅、綠、藍等三 原色的理想亮度比例值各為0.201、0.656、0.141，也就是 紅：綠：藍=0.201 : 0.656 : 0.141，而所欲校正之液晶面 板的紅、綠、藍等三原色的色彩亮度比例值分別為〇 212、 0.701、0·08，也就是紅：綠：藍=0.212 : 0.701 : 0.08。 另外，再假設上述步驟120中「不在其理想亮度比例值一

and more particularly to a color correction method for a liquid crystal panel and a system therefor. [Prior Art] Although there are dozens of suppliers of liquid crystal display panels (LCD panels), the color brightness of liquid crystal panels provided by different suppliers (ie, red, green, blue, etc.) The color brightness of the three primary colors, that is, the so-called R, G, and B color brightness, is not the same. Therefore, the surface of the liquid crystal panel provided by different suppliers tends to be different because the brightness specifications of the two primary colors are different. Color quality is also different. As a result, manufacturers of liquid crystal displays have been greatly troubled because display manufacturers often use the same control board to match LCD panels of different suppliers based on commercial considerations. Doing so also makes the color quality of the display good or bad, and it depends on the LCD panel, which leads to the color quality of the manufactured display. For example, in general, for a liquid crystal panel, the hue of the displayed face is determined by the color exemption of the two primary colors, and the ratio should ideally exhibit an ideal brightness ratio, but most of the The LCD panel is not available to such a ratio. Therefore, among the liquid crystal panels provided by all the current suppliers, some of the liquid crystal panels have a low blue color brightness ratio, which is often caused by the fact that when the kneading surface needs to exhibit the color of the sky 5 200825392 IPD060593TW 22408twf.doc/n The color of the sky displayed by the liquid crystal panel is whiter. However, the blue color brightness ratio of some liquid crystal panels is relatively high, so it often causes the liquid crystal panel to be presented when the surface needs to display the color of the sky. The color of the sky coming out is blue. Therefore, how to adjust the color gradation of the three primary colors of the LCD panel provided by different suppliers to the same ideal brightness ratio, so that the color quality of different Vivid LCD panels can be consistent, that is, all LCD manufacturers must strive to break through Important topic. Moreover, for the user of the display, the quality of the kneading surface often depends on the color of the three primary colors such as red, green and blue. This factor often determines the user's willingness to purchase, and for the manufacture of computers or For LCD TV manufacturers, this factor is even an important factor in the introduction of the second source. SUMMARY OF THE INVENTION An object of the present invention is to provide a color correction method for a liquid crystal panel and a system thereof which can adjust the color brightness of the three primary colors of the liquid crystal panel to an ideal brightness ratio. Still another object of the present invention is to provide a color correction method for a liquid crystal panel and a system thereof which can make the color quality of liquid crystal panels of different brands tend to be uniform. Based on the above and other objects, the present invention provides a color correction method for a liquid crystal panel in which the hue of the face displayed by the liquid crystal panel is determined by the color brightness of the different colors in proportion. The color correction method includes measuring whether a color brightness ratio value of each color in a display face is not within a preset range of the corresponding ideal brightness ratio value, wherein the above 200825392 iJ^DUOUDySTW 22408twf.doc/n color The corresponding ideal brightness ratio value exhibits an ideal brightness ratio. Then, when at least one of the color brightness ratio values is not within the preset range of the corresponding ideal brightness ratio value, each color brightness ratio value is multiplied by a corresponding correction coefficient to obtain the latest color brightness ratio. value. Finally, the display is presented based on the latest color brightness scale value. Based on the above and other objects, the present invention provides a color correction system for a liquid crystal panel in which the hue of the face displayed by the liquid crystal panel is determined by the color brightness of the different colors in proportion. This color correction system includes a brightness sensing device and a judgment correcting device. The brightness sensing device is configured to sense the color brightness of each color of the liquid crystal panel to obtain a color brightness ratio value of each color. The determining correction device is configured to determine whether any color brightness ratio value of each color is not within a preset range of the corresponding ideal brightness ratio value, and when at least one of the color brightness ratio values is not in the corresponding ideal brightness ratio value When the preset range is within, each color brightness ratio value is multiplied by a corresponding correction coefficient to obtain the latest color brightness ratio value, so that the liquid crystal panel can display the display surface according to the latest color brightness ratio value. The ideal brightness ratio value corresponding to the color exhibits an ideal brightness ratio. The color correction method of the liquid crystal panel according to the preferred embodiment of the present invention further includes determining whether the latest color brightness ratio value exhibits an ideal vanishing ratio. When the latest color brightness ratio value exhibits an ideal brightness ratio, the display color surface is displayed according to the latest color brightness ratio value, and when the latest color brightness ratio value cannot exhibit the ideal brightness ratio, the color brightness ratio value is continuously corrected. 200825392 IPD060593TW 22408twf.doc/n The color correction method of the liquid crystal panel according to the preferred embodiment of the present invention further includes burning the latest color brightness ratio value to the basic input/output system of the liquid crystal panel (Basic Input/Qutput gyStem, referred to as BIOS) wafer. The color correction system of the liquid crystal panel according to the preferred embodiment of the present invention, wherein the operation of the determination correction device further comprises determining whether the latest color brightness ratio value exhibits an ideal brightness ratio, and when the latest color brightness ratio value exhibits an ideal brightness When compared, the liquid crystal panel can display the display surface according to the latest color brightness ratio value, and when the latest color brightness ratio value cannot display the ideal brightness ratio, the color brightness ratio value is continuously corrected. A color correction system for a liquid crystal panel according to a preferred embodiment of the present invention further includes a burning device. The programming device is configured to burn the latest color brightness ratio value to the basic input/output system chip of the liquid crystal panel, so that the liquid crystal panel can display the display screen according to the latest color brightness ratio value. According to a preferred embodiment of the present invention. In the color correction method and system of the liquid crystal panel, the above-mentioned one does not include 80 〇/〇 which is lower than the corresponding ideal brightness ratio value within a predetermined range of the corresponding ideal brightness ratio value. A color correction method and system for a liquid crystal panel according to a preferred embodiment of the present invention, wherein a correction coefficient of a color luminance ratio value higher than an ideal luminance ratio value of 8〇% is less than 1 and greater than 〇, which are low The correction factor of the color brightness ratio value of 80% of the ideal brightness ratio value is equal to i. The color correction method of the liquid crystal panel according to the preferred embodiment of the present invention and the above-described colors thereof include red, blue, and green. 8 200825392 IPD060593TW 22408twf.doc/n In the present invention, whether or not any of the color brightness ratio values of each color is within a preset range of the corresponding ideal brightness ratio value by measuring a display surface of the liquid crystal panel. Then, when at least one of the color brightness ratio values is not within the preset range of the corresponding ideal brightness ratio value, each color brightness ratio value is multiplied by a corresponding correction coefficient to obtain a new color brightness. The ratio value, in turn, causes the updated color brightness ratio values to exhibit an ideal brightness ratio, and the ideal brightness ratio is the ratio of the ideal brightness ratio values of the respective colors. Therefore, the present invention can adjust the color brightness of the three primary colors of the liquid crystal panel provided by different suppliers to the same ideal brightness ratio, so that the color quality of the liquid crystal panels of different brands can tend to be the same. The above and other objects, features and advantages of the present invention will become more <RTIgt; [Embodiment] FIG. 1 is a flow chart of a color correction method according to an embodiment of the present invention. The flow of the method is mainly used to correct the color displayed by the liquid crystal panel. Of course, the corrected liquid crystal panel displays the color pupil surface and displays the display surface with the color brightness of three different primary color lights such as red, green, and blue, and the color tone of the display surface is the light of the above three primary colors. The color brightness is determined by the ratio. When the measurement of the liquid crystal panel is started (step 110), it is first necessary to measure whether the color brightness value of each color in a liquid crystal panel is in a display surface, and whether any one of the color brightness ratio values of each color is not in the preset range of the corresponding ideal brightness ratio value.内 9 200825392 lTDU6U^y3TW 224〇gtwf.doc/n (Step 120) 'The ideal brightness ratio value corresponding to the above color presents a desired redundancy ratio. Then, when none of the above color brightness ratio values are within the preset range of the corresponding ideal brightness ratio value, the picture is directly displayed according to the color brightness ratio value (step 16A). However, when at least one of the color brightness ratio values is not within the preset range of the corresponding ideal brightness ratio value, each color brightness ratio value is multiplied by a corresponding correction coefficient to obtain the latest color brightness ratio value. (Step 13〇). Then 'continue to determine if the latest color brightness ratio value exhibits a desired brightness ratio (step 140). When the latest color brightness ratio value fails to exhibit an ideal ratio, the above color brightness scale value is continued to be corrected (ie, returning to step 130). When the latest color brightness ratio value exhibits an ideal brightness ratio, the latest color brightness ratio value is burned to the basic input/output system chip of the liquid crystal panel (step 150). Finally, the liquid crystal panel is caused to display the display surface according to the latest color brightness ratio value (step 160), and the calibration process is terminated (step 170). In order to make the description easier to understand, the following assumes that the ideal brightness ratios of the three primary colors of red, green, and blue are 0.201, 0.656, and 0.141, that is, red: green: blue=0.201: 0.656: 0.141, and the correction is to be corrected. The color brightness ratios of the three primary colors of red, green, and blue of the liquid crystal panel are 〇212, 0.701, and 0·08, that is, red: green: blue=0.212: 0.701: 0.08. In addition, it is assumed that "not in its predetermined brightness ratio value within a predetermined range" in the above step 120 means that it is lower than 80% of the corresponding ideal brightness ratio value. Under the premise of these assumptions, in order to achieve the purpose of the method described in Figure 1, we can design a color correction system correspondingly, as shown in Figure 2. 2 is a block diagram of a device of a color correction system in accordance with an embodiment of the present invention. Referring to FIG. 2, the color correction system is used to correct the liquid crystal panel 21A. As shown in the figure, the color correction system includes a brightness sensing device 22, a judgment correcting device 230, and a burning device 240. The brightness sensing device 220 is configured to sense the color brightness of the three primary colors of red, green, and blue of the liquid crystal panel 210 to obtain a color brightness ratio value of each color. Next, it is judged whether or not the correction means 23 determines whether or not any one of the color luminance ratio values of the three primary colors of red, green and blue is lower than 8对应% of the corresponding ideal luminance ratio value. In the above judgment result, only the blue condition is met, then the judgment correcting means 230 multiplies the red and green color brightness ratio values by different correction coefficients, and the correction coefficients are all smaller than 丨 and larger than 〇 to obtain The latest color brightness ratio values of the two primary colors of red and green. As for the color ratio of the blue color, the value is multiplied by the correction factor of i, that is, no change is made. Then, it is judged that the correcting means 23 continues to judge whether or not the latest color luminance ratio values of the three primary colors such as red, green and blue exhibit an ideal luminance ratio, that is, the aforementioned 〇·2〇ι : 〇.656 ·· 141 141. If the result of the determination is no, then the judgment correcting means 23 乘 multiplies the red and green color luminance ratio values by different correction coefficients, and these correction coefficients are still less than i and greater than 〇, as for the blue color luminance ratio The value is still multiplied by a correction factor of 1 to update the color brightness ratio values of the three primary colors of red, green, and blue until the updated color brightness ratio values of the three primary colors of light exhibit an ideal brightness ratio. In a nutshell, the purpose of the above operation is to reduce the color brightness ratio of a primary color to the red and green colors, so that the updated color brightness ratios of the three primary colors are presented. The ideal brightness ratio. Finally, the programming device 240 burns the color brightness ratio value (ie, the latest color brightness ratio value) that meets the ideal brightness ratio to the basic input/output system chip 212 in the liquid crystal panel 210, so that the liquid crystal panel 210 can be burned according to The color brightness ratio value in the basic input/output system chip 212 appears to be inconspicuous. 10 It can be seen from the above that through the color correction of the present invention, the color brightness of the three primary colors of the liquid crystal panels provided by different suppliers can be easily adjusted to the same ideal vanguard ratio, thereby enabling the color quality of the liquid crystal panels of different brands to be improved. Consistent. As a result, LCD manufacturers no longer have to worry about the color quality of their monitors. In addition, it is to be understood by those skilled in the art that the present invention is not limited to the correction of the color brightness of the two primary colors of red and green. In other practical cases, the present invention also It is possible to correct the color and color brightness of any of the three primary colors of light and the number of primary colors, and the details will not be repeated here. In short, it is in accordance with the spirit of the present invention as long as the color exemption ratio value of the primary color light is corrected so that the color luminance ratio value of each primary color light exhibits an ideal luminance ratio. In summary, according to the present invention, whether or not any of the color brightness ratio values of each color is not within a preset range of the corresponding ideal brightness ratio value by measuring a display surface of the liquid crystal panel. Then, when at least one of the color brightness ratio values is not within the preset range of the corresponding ideal brightness ratio value, each color brightness ratio value is multiplied by a corresponding correction system 12 200825392 iruvoujySTW 22408twf.doc/n The number is obtained to obtain the latest color brightness ratio value, so that the updated color brightness ratio values exhibit an ideal brightness ratio, and the ideal brightness ratio is the ratio of the ideal brightness ratio values of the above colors. Therefore, the present invention can adjust the color brightness of the three primary colors of the liquid crystal panel provided by different suppliers to the same ideal brightness ratio, so that the color quality of the liquid crystal panels of different brands can be consistent. In another aspect, the present invention can also increase the user's willingness to purchase and increase the competitiveness of liquid crystal displays manufactured by display manufacturers. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
