Description

200847123 IX. INSTRUCTIONS: [Technical field to which the present invention pertains] The present invention relates to a method for eliminating the wide-screen display of a display, which is particularly concerned with the absence of a defect. [Prior Art] The driving film of the pixels in the display is π ^ + θ μ, which is the electronic protection of the thin raft (4) effect transistor TFT in the pixels. The system of the land is about..., and the tT of the pancreas is closely related to the precision of the process. Any slight offset of the ruthenium will change the electron conductivity of the TFT Μ (4) or the TFT of the thin film field effect transistor. Due to each

It is difficult to have the same (4) field effect transistor TFT ^ χ ^, so the illuminating conditions of all the pixels of the display are inconsistent. The display shows defects). There is a county pattern defect in the 〇 (the solution to the lack of mura is to change the pixel structure, and directly add the moiré and the coating to the pixel circuit), including a voltage drive (vo tage dnvmg) ^^ . ^ ^ ^ t ( cUrrent driving)

In the voltage driving mode of Lt, at least five thin, ❼a B-day TFTs are required for each pixel, and only the moiré defects caused by the threshold voltage (Vth) of the above-mentioned thin film field effect transistor TFT can be compensated. 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. However, U.S. 6,911,781B2 did not propose new techniques to collect test data, nor did it propose algorithms to compensate for moiré defects. In addition, U.S. 6'9", 781B2 requires a very large memory capacity storage test result. There is a need for a new method to overcome the above conventional techniques. SUMMARY OF THE INVENTION The present invention provides an image display system in which not only a method of collecting test data but also a plurality of ways to eliminate moiré defects are disclosed. t. The invention not only does not need to change the structure of the pixel, but also does not require a space of thinking.

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 sensing elements can also be realized by a corresponding number of current sensors. At this time, the above-mentioned sensing resources are ' ', 3 ancient, electric level value. Due to the sensing data generated by the above sensing elements: no redundancy value 'If the above-mentioned moiré compensation parameter group is to be generated, the amount = line complex conversion 1 is required. The average brightness amount = 122 \ is measured. An average brightness of the pixels is 128. Based on the average, the sensing data of the pixels are converted into a degree data (for example, the unit is Shuai omits the complex conversion required by the traditional technology. The average brightness measuring device 122 is based on the common light on the market (the _^hui f), and the measured average brightness (four) is LAVG. The material is marked as G. As the above-mentioned sensing element i 2 is used The above sensing data G may be a gray scale value, a photoelectron number, or an average current value. The average value of the sensing data G of each pixel is indicated as _. In the embodiment - the calculation formula of the brightness data L of the pixel · L=LAVG · (G/GAVG)r /, medium r is the rounding coefficient, which will be measured according to the sensing component 0773-A32944TWF; P2007010; Gl〇rious Tien 200847123 The linearity between the actual light intensity is different The processing unit 124 will test the ash element by at least one. According to _^, the illuminating characteristics of the pixels are precipitated, and the above-mentioned moiré compensation parameter group of each pixel is generated. 2 The invention describes the gray scale value and brightness data by a variety of algorithms. m Yuan 2: Different moiré compensation parameters will be generated, and the design of the ASIC will also change with the algorithm. , —, , f 2 The flow chart is to generate the above-mentioned moiré compensation parameter group, and the step S2G2 first tests the image with the plurality of test gray scale values to obtain the ancient pixels generated by the various test gray scale values. 2Γ:Γ.4 According to each pixel of a ginseng γ sets it: n (for example, let (4) / γ). Based on the test junction abundance step S204 obtained in step S202, a curve-fitting technique is used to roughly estimate a gray-scale value-luminance relationship of each of The simulation function is as follows: ya X +bx +c.x+d (Function 1) Taking any pixel as an example, y is the grayscale value of the pixel, and X is the grayscale value y. The generated brightness (4), n is the above index = zhang, the values of a, b, C, and d are calculated by the curve fitting technique, and are stored in the memory 112 together with the index parameter n to constitute the pixel. The moiré compensation parameter group described above (step S2〇6). If the parameters of all the pixels are the same, then the index parameter n is a fixed value.

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 "". In the embodiment of the method of Equation 4, the ASIC (1) is fabricated according to Equation 4 to drive a cloud that reads the pixel from the memory 112. Replenishment ^ Received; V:, and n. This specially designed ASIC 114 is connected to the moiré compensation parameter set a, b, c, and η, and its operation action is equivalent to the moiré complement, the compensation function group The moiré compensation function group includes: = L ί less.) , 255 yn and /ΊΑ (Function 5) y is an original grayscale value of the pixel.

The ASIC ιΐ4, a gray scale value y., is converted to a one-step 2 in step S504 by the function 2 'two f The value y is the expected redundancy Xe; in step S506, the function xe is converted into a band, and the #w is 5, which is expected to be used by the integrated circuit 114 to drive the wheel step _, which is driven by the original (four) value η = Tree value... In place of the defect, W丨ί2 (S304) will make the invention more capable of satisfying the display of the Gamma parameter γ and the peak peak white point (Whlte p〇im) setting. For the above-mentioned Gamma parameter 7 and the peak dedicated road 114 end, after the display system is depleted, the user can change the value by designing the output worry test. The flow chart of the brother 6 is to generate the above-mentioned moiré algorithm. Step S6〇1Bei>The other pixel of the number, and the number of test gray scale values of the corpse I test the data of the Yuan products V: the test results generated by various test gray scale values: degree =: In step S6G4, the brightness data will be a desired gray level value:

The money management unit 124 stores the upper 34 gray scale value difference in the above-mentioned gamma compensation parameter group corresponding to the gray value of the memory risk value difference. The fake mouth and this household's example use a total of QVGA (Quarter vGA, which is the human white value of 112 rabbit μ GBW) as an example, the memory

For m arrays, the size is 32Gx24G and W pixels are used. In this embodiment, the application specific integrated circuit 114 is a must (or a subtractor). Taking the driving of 彳一彳, /, "直田隹二$ pixels as an example, the seventh diagram is a flow chart depicting the action of the circuit 114. The special step S702 receives a square p ratio. % determines the size of the original gray F white value in step S704; and selects the near test grayscale value in step S7〇6, so that the meaning of the original white, +, > Calculating the step difference compensation The original value will replace the original gray level value to drive the pixel. 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. The luminance data of the pixel pair 0773-A32944TWF; P2007010; Glorious Tien 200847123 == value will be step ss〇4 Converted to Λ Λ / L peak 255 甘Λ 4 (Function 6) 7ί /, respectively 'Xt is the above luminance data, and h is the required grayscale value. «Formula 6 will ensure that this "satisfies the Gamma parameter γ of each pixel. The processing unit 124 spleen #丰值儿度Lpeak and one, 斤早兀124 will be in step S806 for each silly different test the grayscale value and the required grayscale value & - grayscale value difference, And in step S808, a plurality of specific gravity parameters and the grayscale value difference are stored in the memory 112. 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.
