Description of the invention (1) The technical field to which the invention belongs The present invention relates to a liquid crystal display panel (LCD panel) ', especially a low-brightness bright liquid crystal display panel. In the prior art, thin film transistor LCDs mainly used thin-film transistors arranged in a matrix and equipped with appropriate electronic components to drive liquid crystal pixels to produce rich and beautiful graphics. Thin-film transistor liquid crystal display panels are widely used in portable information products such as notebooks, personal digital assistants (pDA), etc., due to their thin and light appearance, low power consumption, and no radiation pollution. CRT monitors have gradually replaced traditional desktop computers. First, please refer to FIG. 1 and FIG. 2 ′. FIG. 1 is a schematic diagram of a conventional thin film transistor liquid crystal display panel, and FIG. 2 is a schematic diagram of an equivalent circuit of a single pixel of a thin film transistor liquid crystal display panel. As shown in FIG. 1, a liquid crystal display panel 10 includes a lower substrate i 2, and the lower substrate 2 includes a pixel = pixel area 14, a scanning line driving circuit area 16, and a material line driving circuit. District 18. The pixel array region 14 includes a plurality of scan lines (not shown) and a plurality of data lines (data

No); and each of the scan lines and each of the data lines define a complex ΐ, Λ Π), as shown in the pixels A ~ C and pixels Λ R, R shown in the figure—: A to C are electrically connected to the same scan line, and pixels A, B, and C 'are electrically connected to the same data line. As shown in Figure 1, the scan line driving circuit area 6 includes a plurality of ^ 7 dynamic integrated circuit chips (such as wafers 16a to 16c) and a plurality of bus lines, and each bus line 17 is used to electrically connect each The driving integrated circuit chip. Each of the driving integrated circuit wafers is directly fabricated on the surface of the lower substrate 12 using chip-on-glass (COG) technology, and each of the bus lines 17 is also directly fabricated on the lower substrate 丨 2, that is, The so-called w〇A (wiring on array) design. As shown in FIG. 2, a pixel 20 includes at least a liquid crystal cell LC and a thin film transistor TFT. The liquid crystal cell LC is composed of a pixel electrode, a common counter electrode cE, and a liquid crystal. Made up of molecular layers. The thin film transistor TFT includes a gate electrode connected to a scan line GL0, a drain connected to a data line DL0, and a pixel electrode connected to a source electrode of the liquid crystal cell LC. Since the gate and the source electrode Partial overlap results in a parasitic capacitance Gs between the gate and the source. In addition, the pixel 20 further includes a storage capacitor SC connected between the liquid crystal cell LC and a scanning line GL 1 'The storage valley SC is used to reduce the influence of the leakage current on the voltage of the liquid crystal LC cell, that is, used to Assist the liquid crystal cell LC to store charge.

Because it is applied to the fixed relationship, the light transmittance in the liquid crystal cell LC is reconfigured. However, if the CE and the pixel electrode of the pixel electrode are not in a floating state, they will pass the voltage, thus making it a fixed value. And this voltage (VFD), as long as the voltage on the liquid crystal cell LC can be combined with a uniform light voltage difference between the liquid crystal cells, connected to any voltage 'at this time the capacitance of the pixel electricity is coupled and applied The amount of change in the single voltage of the liquid crystal is called: it can be expressed as: The voltage to be displayed will be each source, which will be the thin film source on the LC, and the pole's circumference will be the same as the feed current and light transmission on the pixel LC. The picture is used to control the application pixel settings. When the display can be pre-powered, the common electrode is a common electrode. When the transistor TFT is turned off, if there is any voltage-varying electrode in the floating area, and its voltage deviates from the original set voltage (f eed -through (1)

Generally =, by adjusting the voltage of the common electrode CE, the shirt sound of VF can be eliminated. However, Due to the resistance and capacitance effects in the scanning line, the negative edge of the pulse voltage applied to the scanning line will be rounded, so Vfd will be swept away from the pixel knee. The farther and smaller the input end of the Putian line, the smaller

594347 V. Description of the invention (4) It means that the V F fishing relationship of the pixels A, B and C shown in Fig. 1 will be (V FD) A > (V FD) B > (V FD) c. Therefore, it is difficult to eliminate the influence caused by the V F of all pixels by adjusting the voltage of the common electrode CE, which will cause the liquid crystal display panel 10 to produce a day-to-day flicker (f 1 i c k e r). On the other hand, since the bus lines 17 in the scan line driving circuit 16 have a relatively large resistance value, when a pulse voltage is input from the bus line 17 to each of the driving integrated circuit chips, each of the driving integrated circuits is 9 The input voltage of the chip will be different, which will result in different waveforms of the output voltage of each driving integrated circuit chip. For example, as shown in FIG. 3, the voltage difference (△ V GA) outputted by driving the integrated circuit chip 16 a is the highest, and the voltage difference (△ V GB ') outputted by driving the integrated circuit chip 16 b is the second, The voltage difference (△ VGC ') output by the driving integrated circuit chip 16c is the same again, thus causing V FD to decrease as the pixel is farther away from the input end of the data line, which is shown in Figure 1. The VF # j relationship between the pixels A, B ', and C' is shown as (V FD) A > (V FD) B > (V FD) C 'Thus causing the screen to flicker.' Reduce the display of the LCD panel quality. SUMMARY OF THE INVENTION An object of the present invention is to provide a low-flicker liquid crystal display panel, and each pixel in the liquid crystal display panel has approximately the same V FD to improve the aforementioned defects.

As shown in Figure 4, the equivalent circuit 40 at least includes people and vice versa, and the positions of the pixels a, B, and C correspond to the pixels-pixels A, A, B, and C, respectively. The pixel A includes a liquid crystal cell LC, a wax, and an image T a.

594347 V. Description of the invention (6) A prime electrode, and since the gate and the source partially overlap, a parasitic capacitance GS is formed between the gate and the source. In addition, the pixel A further includes a compensation capacitor C ′ A and a storage capacitor SCA. The compensation capacitor C ′ # is connected to the pixel electrode of the liquid crystal cell LC and the scan line GL0, and the storage capacitor SC is connected to the pixel electrode of the liquid crystal cell LC and the scan. The line GL r is the same, the pixel B includes a liquid crystal cell LC, a thin film transistor TB, a storage capacitor SCB, and a compensation capacitor C ′ b, and the thin film transistor T 妁 gate and the source system partially overlap, so Generate a parasitic capacitance GSB. The pixel C is composed of a liquid crystal cell LC, a thin-film transistor Tc, a storage capacitor SCc, and a compensation capacitor C '. Since the thin-film transistor T 妁 gate and the source system partially overlap, the pixel C It also has a parasitic capacitance GSC. As shown in Figure 4, since the compensation capacitors C'a, C ', and C'df are connected to the capacitors GSA, GS, and GS, respectively, equation (1) can be rewritten as: V FD = [(C GS + C) / (C LC + C SC + C GS + C)] * △ VG (2) where C is the capacitance of the compensation capacitor C ′. In general, in equations (1) and (2), the capacitances of the storage capacitor SC and the liquid crystal cell LC are about several tens of times the parasitic capacitance GS and the compensation capacitance C ', that is, Csc, CLC > > C GS, C, so equation (2) can be simplified into the following formula:

Page 13 594347 V. Description of the invention (7) V FD = [(. GS + C) / (C lc + C sc)] * △ VG (3) As shown in Figure 4 and equation (3), because the scanning line GL decays Resistance and capacitance effects (as described above) ^ If (C GS) (C GS) B = (C GS) C, (C SC) A = (C SC) B = (C SC) C, (C lc) A = (C LC) B = (C LC) and C a = CC c 'Then the approximate relationship between V f of pixels A, B and C will be (V fd) a> (V fd) (V fd) C 'And this will cause the day and night flicker of the LCD panel. Therefore, in order to reduce the occurrence of daytime flicker in the LCD panel, the V FD of the pixels A, B and C must be made about the same. According to equation (3), the compensation capacitance C ′ and gate of each pixel can be adjusted. The parasitic capacitance C cs between the source and the storage capacitance C sc is used to achieve the purpose of making V FI ^ j of each pixel slightly the same, and the adjustment method is: (1) as shown in equation (3) CA <C B &lt; C c, (C GS) A = (C GS) B = (C GS) C,

(C SC) A: (C SC) B = (C SC) and (C LC) A = (C LC) B = (C LC) C ′ Be J The VF 妁 relationship between pixels A, B and C can be (V FD) A «(V FD) B« (V FD) c. Therefore, if the capacitance c of the compensation capacitance c 'is gradually increased as the pixel is further away from the input end of the scanning line, the V F of each pixel can be made approximately the same. (2) As shown in equation (3), when (C GS) A &lt; C GS) B <(C GS) C, CA = CCC, (c SC) Α = (C SC) Β = (C SC) and (C LC) Α = (C LC) Β = (C LC) C ′ can also make the relationship of VF of pixels A, B, and C to (V FD) (V FD) (V FD) C. Therefore, if the capacitance C of the parasitic capacitance G S of the left pixel increases from the input end of the scanning line and increases, the V F of each pixel can be made slightly the same.

Therefore, if the storage is reduced, the VF of each pixel will be about the farther away from the input end of the drawing line, and the VF of (1), mode (2) and mode (3) will be about the same purpose. the way. It is worth mentioning that the above methods can also be matched with each other to achieve each pixel. The following description is a specific implementation of the present invention.
