Description of the invention: [Technical field to which the invention pertains] In particular, it is used by the [prior art] [0002] that the current technology industry is booming, especially the faster the photoelectric, the market for various photoelectric display products === = Re-listing, the quality of the display image is required to do the best. After the adjustment of the ageing device =003] In the liquid crystal display, in general, in order to make the liquid usually use a gamma curve with a gamma value equal to 2·2 ΐ The reason is that the ship's ship feels that it is not new to the correction. The singularity and the sacred material must be converted into a voltage by a gamma curve with a gamma value equal to 2.2, so as to present a human visual experience. Natural imagery, in addition, the gamma curve in the practice of road design, usually take a number of reference points on the curve - gamma to Zhao, the data can be quickly converted into voltage through this table, and then 'to the bandits It comes to imaging 'but although the above gamma curve can be adjusted, it is an important factor in the quality of the conventional technology, so the display quality of the 'practical technology' can not be delayed. [0004] due to the liquid crystal display In the automatic adjustment of the color temperature of the board, the curve of integration 2 is the factor of brightness. Usually, the color history of this line is assumed, and the most expensive color temperature is found. Then, according to the operation of the gamma curve, The closest red, green, and blue gamma comparison table, but because of the liquid crystal display panel 6 5 1377536 I · Using the [adjusted n' to avoid the shortcomings of the above-mentioned conventional techniques, it is necessary to develop a new type of farmer The display quality of the device and the adjustment efficiency of the display. SUMMARY OF THE INVENTION The gamma pair c is used to store a gamma curve by a gamma curve and a color temperature curve, and is suitable for a liquid crystal display. The gamma table is displayed by a comparison table: ^ and 3 steps The conversion relationship, the liquid crystal display according to the gamma pair - gray point point to the "head" d3 to: step: first 'in the liquid crystal display color coordinate value - the current color temperature value, - first current ==: current The color coordinate value, the second current target color coordinate value, the second day charge = degree knife and the target color temperature value, the first error - not less than "the second one seat "value f" - the conversion relationship between the target brightness and the gray level is adjusted by the brightness of the plurality of color lights in the gamma comparison table and the current gray level point displayed by the target respectively. In the case of the minimum error, then the value of the method of the present invention is to add a color-defining panel characteristic to the adjustment of the gamma curve, and to consider the color shift factor, so that: automatic 1373736 [Embodiment] [0009] The purpose of the present invention is to describe the present invention. The purpose of the present invention is not to define the present invention. ^=Special $==1 range and close type are fully understood. Miscellaneous can be used to patent [0010] The present invention is on the general gamma curve > =: ί ί and f progression!,, The invention is suitable for gamma: it can further enhance the display of the school, repair LCDTV 〇^n:=;; w^ curve adjustment on Silicon), etc., and can be applied in image processing) and fC0S (^md coffee such as dry Cry for you, but also for the money--, set. The embodiment of the present invention uses liquid crystal [0011] first _ heart according to the present invention to implement a two-color temperature curve to adjust the gamma table method ίί ϊ = = ί A gamma curve is used to store the voltage and grayscale transition surface system, and the gamma is displayed on the silk, and a 5-week gamma comparison table is considered in consideration of the color temperature factor. The financial method includes the following steps: first, in step S101 For the H-order point, the target value is given to the variables x, y, ct. The target value can be set, for example, by setting the target color temperature value for the variable CT, setting the first target color coordinate value for the variable 、, and setting the second target for the variable y. The color coordinate value 'the towel's target color coordinate value and the second target color coordinate value meet the Omnanatid Diagram (in accordance with the __ committee's specifications) 0^1931)' can determine the color according to this, but when the target color temperature value is given, the first target color coordinate value and the second target color coordinate value are determined accordingly. In addition, the gray level point is to adjust the color mi The gray scale point can be any value within the gray scale value 丨 256. Therefore, the present invention is implemented 8
