Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal display having a multi-region with a liquid crystal display element. In particular, the second [previous technology] is currently the most commonly used in thin film power plants; LCD) is 'flat':: f (ni-plane switching, lps) and: ? conversion compensation film has the most Good perspective: Color: J 7 7 ί: Ϊ Ϊ Ϊ Ϊ, but its contrast is relatively wide and manufacturing ΐ than #古, 伯3i i has a relatively good yield to the dry type, The compensation film can be used with a wide viewing angle to achieve a wide viewing angle and is not as good as a plane conversion in color performance: when viewed at an oblique angle, Asian fafh:t 2) C〇1〇r, the solution to the partial problem can be improved by producing different gamma curves in a sub-study (the effect is added to the mixed effect), and this technique is called halftone f-tone^, where Each pixel corresponds to a red, green, or & color, and the most direct way to produce a different gamma curve in a sub-sequence is to divide it into two regions within a sub-salm, It is also about to divide the original 昼 昼 昼 , , , , , , , , , , , , , , , , , , , , , , , , , , There are a total of three sub-success circuit designs. Please refer to Figure 1, which is the first special-purpose circuit diagram of the half-tone halogen. It reveals a first-type sub-tin 1 , package 5 200839393 1 Chu i ^ line DL, a scan line gl, and a common line. Stored in the ray=subsequence 1 is further provided with a thin film transistor 10, 〆, and 1111 connected to the common line CL and the thin film transistor 10 data line Di^ Then connected to the pole of the thin film transistor 。. The $t line GL is connected, and the gate of the thin film transistor 10 respectively 曰# type 昼素素1 退 includes two liquid crystal capacitors, Ub, and H a liquid crystal capacitor 12a and The liquid crystal capacitor film Ua has a first-electrode electrode ia connected to the drain having the f 10th, and the second liquid crystal capacitor 12b 1, #一#\electrode 1b.

Separating the potentials of the two liquid crystal capacitors, and generating the same gamma curve of two T, the structure is simple, and the added electron elements and the more important enthalpy traces are not increased, so the influence on the openings is small. The problem caused by the series capacitor 2 3 = in the operation of the panel, it will capture the charge and cause the potential of the second = prime electrode lb to shift the set value to generate image debris, in addition to reliability problems, A phenomenon of water ripple (mura, also known as moiré) that causes uniform color and brightness. Please refer to Figure 2, which is the attack circuit diagram of the second conventional halftone pixel. It is characterized in that two j-gamma curves are generated by directly giving two gamma values through two thin germanium crystals and two gate lines or two data lines. Figure 2 discloses a second type of second 壹夭 2 ', including a first scan line GU, a J-scan J, a, and a parallel line between the two, and a poor material The line DL 'second type secondary halogen 2 further includes a first film, the gate of the crystal 2〇a is connected to the first scan line GL1, and the gate of the germanium transistor 20b is connected to the second scan line. The drain of the first thin film transistor 20a is connected to the common line CL through a turn 2U, and the drain of the second thin film electrical body 20b is connected through a second storage line CL. And the first thin film transistor...the drain of the first thin film transistor: a young crystal capacitor 22a and has a first pixel electrode; the capacitance meter can be changed in two sub-additions, and the And the 30a is connected to the second thin silicon transistor 20b, and the second thin layer has a second halogen electrode 2b. Although this ΐ 1 directly and effectively produces two sets of gamma curves = - a wire such as a scan line, θ produces, that is, the aperture ratio is reduced, and the scanning drive is also doubled (if It is to double the data drive with the Bellow line),
