In this current driving mode, at least four thin film field effect transistors are required for the mother pixel, and the compensation ability for low gray scale values is not good. This method of changing the pixel structure usually requires more thin film field effect transistor tft, which not only affects the pixel opening ratio (Aperture rati), but also is not suitable for high resolution 773-A32944TWF; P2007010; Glorious Tien 200847123: On the display of the degree (for example, 2忖 qvga or higher resolution). The system technology not only affects the light-emitting characteristics of the pixels, but also increases the area of each pixel. The proven technology is external compensation technology (externai: pensatiGn). U.S. Patent Nos. u s· 6, 9u, 78ib2 adjusts the gray scale value of the pixel according to the test to compensate for moiré defects.

The image display system of the present invention further includes a memory 112 and an application specific integrated circuit (ASIQ 114. The memory 112 stores a moiré compensation parameter set of the pixel. The gray scale value signal (10) outputted by the surface source 1Q6 is converted into a signal 116 by the dedicated Huacheng circuit m before being converted into a voltage value. Taking the pixel 1〇4 as an example, the dedicated integration=:14 reads the functional equivalent of the cloud-like compensation parameter t of the image-like Q4 from the record (four) 112, and the function is equivalent to the moiré compensation function 1^4. You Tian Xuanyu 1G4 - the original grayscale value y. The ASIC / will be converted to the H gradation value ye to replace the two π fire! 1 white value y. Enter the digit/analog converter 11〇. The moiré is converted into a voltage value by the digital/analog converter ug to become a signal for driving the pixel 104. The suffix 112 stores the good band, and the generator m is generated.

Because the white point (white point) is set It is determined by the brightness of the ♦ value of each color (red ς = blue) pixel, so the shadow system can also easily be set to the user's white point setting. The ASIC ιΐ4 'the above ginseng ginseng' and the peak value The brightness of the Lpeak_ design output, so that the 5 Hai display system, the user can still change the value of the user. The flowchart of Fig. 4 is another algorithm for generating the above moiré compensation parameter set. Step S402 first tests the pixels with a plurality of test gray scale values to obtain luminance data generated by each pixel driven by a plurality of gray scale values. This algorithm divides the display into a plurality of blocks, each of which will have a different index parameter η according to its electronic characteristics. Step 4〇4 sets its exponential parameter η according to the area where each pixel is located. Based on the 戦 result obtained in step S402, (4) 粗 —-, line fitting (four) ^ _ng) technology rough estimation of each pixel - gray scale value brightness relationship simulation function is: y-, (function 4) in any pixel For example, y is the grayscale value that drives the pixel, X is the luminance data generated when 1 pixel is at the grayscale value y, and n is the finger parameter of the pixel. After a, b, and c are calculated by the curve fitting technique, the index parameter n is stored in the memory 112 to form the moiré compensation parameter group of the pixel (step S408). When ρ is compared with function 1, the biggest difference of function 4 is the choice of the exponent parameter ^. Analyzing the illuminance characteristics of a display, it is found that the pixels located near the power line are brighter because of the ohmic drop on the power line. 0773-A32944TWF;P2007010;Gl〇rious_Tien 'If the parameter value of the display is not correct, it will be able to estimate the proper light characteristics more accurately and select the appropriate index and reduce the complexity of the analog function;:: Gray scale value of the prime - Brightness relationship, just calculate a, b, and. The three ^ functions 4 are reduced compared to the function 1, and the number of bytes is also reduced. 〃, at the same time storing each parameter required to set the sampling in the reference block of each area, counted as a hard number of blocks; above to estimate the "-" of each block: number: number of primes , the number of the number is the above index parameter of the corresponding block. 7 & average index W^QVGA (QUaner VGA, 3 chest 4GXRGBW) as an example, this Beth mode memory 112 will store each case, a: - WR, G, B, two two: Compared, this The embodiment saves a large amount of "".

Xiao & and ^ compared with other embodiments of the soil, this embodiment calculates the above-mentioned moiré compensation minus (four) The horse parameter 丫 and the peak truth degree Lpeak. However, in the case where the moiré defect of the display is not serious, in order to save more space for the memory, the present invention proposes another method of 渖法. The flow chart of the above-mentioned moiré compensation parameter group is only tested by a test gray scale value.

Taking the 值 white value difference as an example, the gray scale value difference corresponding to the test gray scale value and the specific gravity parameter are the moiré compensation parameter group. Since only one test gray scale value is used for this embodiment. For example, er VGA ’ 320 Rgbw), in addition to storing the specific gravity parameters, the memory basket only needs to be used—the array space coffee (10) is called for R, G, B, and w pixels). Compared with the embodiment described in Fig. 6, this embodiment will greatly reduce the space requirement of the memory ι2. In this embodiment, the application specific integrated circuit 114 also includes an adder (or subtractor). Taking a certain pixel as an example, the operation of the ASIC 114 is described by a flowchart. The ASIC 4 receives the original grayscale value in step S902; determines the size of the original grayscale value in step S9〇4; selects an appropriate specific gravity parameter according to the size of the original grayscale value in step S906, and the specific gravity The parameter is multiplied by the above gray scale value difference 〇 773-A32944TWF; P2007010; Glorious_Tien 16 200847123 specific gravity gray value difference. The ASIC 114 will compensate the original grayscale value by 比重8 with the specific grayscale value difference to calculate the grayscale value. The moiré elimination gray scale value will drive the pixel instead of the original ash 卩0 value. The sensing element is a flow chart of the present invention. Step Si_ provides a plurality of pixels corresponding to a display, each of which generates a root.
