DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates to a method for adjusting a display device, and more particularly to a method for adjusting a gamma comparison table. [Prior Art] [0002] In the development of modern science and technology, the optoelectronic technology industry is changing rapidly, and the quality of various optoelectronic products is becoming more and more refined. 'The display surface produced by the manufacturer's initial production ^ Only in order to accurately meet the needs of human vision can it be promoted to the market smoothly. As for the part of the adjustment, for example, 'human _ visual perception is not linear. When the light is dark, the change of the f-order is recorded as the difference between the gray level and the difference when the crane is bright.视觉ίί visual differences have been adjusted in the prior art using gamma values ί i , curves, which are stored in a curve rather than a straight line. Therefore, the voltage converted by the gamma curve is added to the ϋ曰 knife, which can change the amount of light _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The door ° is usually produced - a gamma comparison table to describe the gamma curve, ί: ΐ 义: 义二 ======= 1 to the color temperature and other influencing factors to Xia. _ 疋 而 要 再 再 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - The quality of the image, according to the effect of this display to do the details of the = whole, for example, the adjustment method is one of the areas of the face of the color is not normal %, to find out which specific in this area The gray scale display is not normal, only the month ^ for a few gray scales to make detailed adjustments, in general, the current technology uses trial and error, that is, guess which gray scale is a problem, then try Add and subtract voltage to adjust to see. ~ [0005] Furthermore, when the color development* of the above area is normal, many adjacent color gradations are displayed by the area, and it is difficult to directly determine which gray level has a problem, in the case of using 256 gray scales. There are 256 possibilities in the worst case, so such adjustment methods will face the disadvantage of inefficiency. [0006] For this reason, for the current efficiency and product _ optoelectronics industry, the conventional method is no longer sufficient, and even more, the display size currently produced is becoming more and more popular for the resolution and image quality. Picky, but must be adjusted to the gamma table. Μι(四) ❹ [Summary of the Invention] [0007] The object of the present invention is to provide a method for speeding up the adjustment of a gamma comparison table, which is suitable for a liquid crystal display, and the gamma comparison table is used for storing a conversion relationship of a voltage g gray scale. The liquid crystal display according to the gamma comparison table to display the method includes the following steps: inputting a data; giving a target level to each of the gray levels in a room, so that the gray level display interval Each of the levels is the same as the display - the target gray level; and if one of the liquids in the display area of the input data indicates that the target gray scale is displayed, the color temperature of the target gray scale is displayed by the second element , by correcting the conversion relationship between the voltage and the gray level in the color gamma comparison table. The dish is used to adjust the gamma 200929163. [0008] The method for accelerating the adjustment of each of the specific display areas of the gamma is provided by the present invention, because the gray scale in the specific display interval of the singular The number can be adjusted to adjust 'and the number of gray P white can determine the method provided by the image while taking into account both speed and quality. X, thus the present month [Embodiment] 结构ίΐϊ The structure and method of the present invention. The content of the present invention explains the invention of Zhang Xingfan. The invention is defined by the scope of the patent application. The actual and characteristic 'points and advantages' will be fully understood through the following description of the patent scope and the drawings. The method of the Ϊ Ϊ f, applies to any gamma curve that needs to be adjusted to adjust the brightness of the LCD (LiqUid Clystal Panel 9 ^ ίίi 2Γ ieGn 'Si (4) panel material, both of which are described in detail herein, in This will be based on the liquid crystal display 佑 液 ί ' display 'usually based on a gamma curve to produce gamma: ^ ' 储存 stored in each of the specific points on the comparison table voltage and gray scale conversion relationship: therefore, the liquid crystal display can be based on the gamma Ma comparison table to display the image in practice f said 'when adjusting the gamma curve, as long as the value on the comparison table can be adjusted, that is, the ten 'Z directly update the value on the corresponding check on the comparison table, so In the embodiment of the present invention, in the gamma comparison table, it is found that some gray scales of abnormal color rendering are done with "weekly" and filled with updated values to improve the display capability of display II, * adjusting the gamma contrast, In the embodiment of the present invention, the method of adjusting the color temperature may be used to correct the value of the pair on the gamma comparison table. 200929163 [0012] In the embodiment of the present invention, a data may be first input to the display panel for testing. Color development in a certain area Normally, the gamma comparison table can be corrected. Please refer to FIG. 1 and FIG. 2'. FIG. 1 is a flow chart showing a method for accelerating the adjustment of the gamma comparison table according to an embodiment of the present invention. The figure shows a distribution map of gray and gray in accordance with an embodiment of the present invention. In step S101, each gray level in the gray level display interval is given from the target level to the gray level display interval. The level of each of the gray scales is the same and both display a target gray scale. That is to say, for example, the gray scale display section 201 shown in Fig. 2 sets the gray scales 1 to 8 The same target level, that is to say, the brightness of the eight gray levels are the same, and because the collective brightness is the same, so it is quite obvious on the display surface, and it is easy to find the problem area, and further into the second step. Ground, these 8 gray levels can be set to the highest gray level (gray level 256), if it is set to the most gray level, if the abnormal color area of the gray color 256 suddenly appears, it can almost judge It is a gray scale error in the gray scales 1 to 8, so the present invention provides an efficient method to solve The problem of abnormal color development. X ', [0013] Figure 3 is a diagram showing the sound of a display panel according to an embodiment of the present invention. The area f = 3 areas of abnormal color, the gamma comparison table must be adjusted. ® Do not adjust the gray level of the area in the hanging area. Please refer to Figure 1 and Figure 3 at the same time. In the S103, 'If you enter the data in the LCD, the 3 pixels are 0 pixels: Target gray level. , then judge the input pixel falls in the target, = Shi Fan ^, that is to say, if we show the gray level 〗 〖8, the highest reversal point does not appear in the area where the color is not normal, then Entering the step, the field returns to the original data, but when these bright spots appear in the display, the process proceeds to step SU) 7, and it is necessary to highlight the light gray of the bright pixel.诼常, and adjust 200929163 [001=] Step S105 and step S107 represent two cases of correction or no correction, if there is no pixel in the display area of the liquid crystal display of the data, the target is displayed In the gray scale, in step S1G5, the age of the original data of the target gray drop displayed by the pixel is not corrected, and if the data is input in the liquid crystal display of the data, there is any When the pixel displays the target gray scale, S107 corrects a color temperature of the target gray scale displayed by the pixel, wherein the conversion relationship between the voltage and the gray scale in the gamma comparison table is adjusted by correcting the color temperature. 00 [0015] According to the method provided by the present invention, the gray level of abnormal color display can be immediately found to adjust the color temperature, taking into consideration the efficiency and quality. The above embodiment takes the gray scale b 8 as an example, when the gray scale 1 to 8 is normal. 'Can be analogized to grayscale 9~16, 17~24 and so on. Referring to FIG. 2, in this embodiment, the full gray scale (for example, 256 gray scale) is divided into 256/8=32 gray scale display intervals, and each gray scale display interval includes only 8 gray scales, as follows: The order display interval 201 includes gray scale 1 to gray scale 8 'gray scale display interval 2〇3 includes gray scale 9 to gray scale 16, gray scale display interval 205 includes gray scale 17 to gray scale 24, and gray scale display interval 2〇7 Including, order 25~32 'The rest of the grayscale display interval can be deduced by analogy. Then, the display interval can be set to the brightest brightness of the grayscale 256 in sequence, until the entire color temperature value is adjusted after the abnormal value is found. [0016] Those skilled in the art will recognize that the embodiments of the present invention are not limited to setting the grayscale display intervals 201 to 207 to the brightest brightness of the grayscale 256 in sequence, and different target levels may be given depending on the requirements thereof. In the embodiment of the present invention, the color temperature is adjusted by using 8 gray scales as an interval, and the value on the comparison table is changed according to the adjustment. Interpolation can be used between the color temperature points to obtain the value of the intermediate point. . [0017] Those skilled in the art are aware that each grayscale display interval is not limited to including 8 gray scales, and can be adjusted to include 16 gray scales or more gray scales, or visually demanded to include 4 Gray scale or less gray scale, the reason is that when the gray scale display interval 200929163 number u contains more gray scales, the speed is faster and the circuit complexity is 3j and the gray scale display interval When the gray scale is included, the display quality is better, so the gray scale included in the gray scale display interval of the embodiment of the present invention may be increased or decreased according to the demand [0018] although the present invention has been described with reference to the preferred embodiment. The description, as will be understood by us, is not limited by the detailed description of the present invention. Alternatives and modifications are suggested in the previous description, and other alternatives and modifications will be apparent to those skilled in the art. In particular, all of the structures and methods of the present invention, which are substantially identical to those of the present invention, are substantially the same as the present invention, without departing from the spirit of the invention. Accordingly, all alternatives and modifications are intended to fall within the scope of the invention as defined by the appended claims.
