New description: [New technical field] [0001] [0002] This creation relates to a liquid crystal display, especially a pixel structure. [Prior Art] Since the production technology of the Liquid Crystal Panel and the Back Light Module is becoming more and more mature, when a liquid crystal display (LCD) is used in resolution, weight, thickness, When the reaction speed and power consumption are superior to those of conventional cathode ray tube (CRT) displays, liquid crystal displays have gradually replaced traditional cathode ray tube displays, so liquid crystal displays are the most common displays today. —. The screen of the liquid crystal display contains a plurality of pixels, 098208393 Form No. A0101 Page 2 / Total π page 0982027206-0 M366088 Each pixel contains a fixed area of liquid crystal for displaying images and using at least one thin film Crystal (Thin-Film Transist Qr, TFT) = controlled. Since the liquid crystal is deflected by the electric field to change the transmittance of the light, when the liquid crystal display displays an image, a voltage is applied to the liquid crystal in the pixel region by the control of the thin film transistor, and the pixel is controlled. The tilt angle of the liquid crystal in the area, so that the transmittance of light to the liquid crystal can be controlled, and the brightness of the pixel can be controlled. Please refer to the first figure, which is a schematic diagram of a conventional pixel structure. As shown in the figure, the conventional structure 10 includes a scan line 12, a data line 14, and a

Generally, the gate 161 and the source 162 are connected. The parasitic capacitance Cgs will be derived, and the gate 161 and the drain 163 will generate a parasitic capacitance Cgd. However, as shown in FIG. A, the pixel structure 10 is in a case where no process offset occurs, so the parasitic capacitance Cgs and the parasitic capacitance Cgd are not changed, and if the process is shifted and the parasitic capacitance Cgd is greatly increased, the input is performed. The voltage is heavily affected by the parasitic capacitance Cgd, which is the voltage level (Δν) caused by the parasitic capacitance Cgd, which causes a large amount of change in the input voltage. However, the parasitic capacitance is unavoidable in the semiconductor process. Generally, the parasitic capacitance is derived around the thin film transistor, for example: the capacitance Cgd between the gate and the drain of the thin film transistor, so the liquid crystal display The influence of parasitic capacitance is considered in the calculation of the input voltage, and the capacitive coupling parameter affecting the input voltage is ((Vgh- 098208393)

Since the parasitic structure shift causes the parasitic electric valley Cgd to increase greatly, the pixel capacitance and the storage capacitance are reduced. Thus, the input voltage applied to the pixel structure via the thin film transistor control is affected by the wire value corresponding to the parasitic capacitance Cgd, that is, the voltage valley corresponding to the parasitic capacitance. The bit (Δν) conducts (4) the input voltage applied to the pixel produces a level shift, which in turn reduces the display quality of the liquid crystal display. In order to compensate for the influence of parasitic capacitance during process offset, a capacitor compensation method has been developed, as shown in the second figure. Please refer to the second figure, which is a schematic diagram of a conventional halogen structure with a compensation capacitor. The difference between the pixel structure 10 of the first figure and the pixel structure 20 of the second figure is that the gate 261 extending from the scan line 22 of the second figure extends an extension 266 to the drain 263, since the extension 266 is It is disposed along the halogen electrode 28 and extends to the drain 263' so that the pixel electrode 28 is drained to the drain 263 of the thin film transistor 26 via the via 265 by way of a trace. The conventional structure 20 is offset in the process, wherein the thin film transistor 26 causes the parasitic capacitance ca to generate a shift capacitance change amount ΔΠ due to the offset, and the extension portion 266 compensates the compensation capacitor CC at the drain 263, wherein The compensation capacitor CC includes the offset capacitance change amount Δ C2, and AC1 + AC2 will approach 0, thus compensating for the amount of capacitance change caused by the process offset. However, the extension portion 266 shown in the second figure causes the halogen electrode 28 to bypass the trace 266 of the extension portion 266 to electrically connect the drain 263, so that the aperture ratio of the halogen-derived structure 20 is decreased, and the compensation capacitor is passed through the compensation capacitor. After cc compensation, the capacitance value of the parasitic capacitance Cgd will increase, which will reduce the influence of the halogen capacitor and the storage capacitor on the capacitive coupling parameters. 098208393 Form No. A0101 Page 4 of 17 0982027206-0 M366088 The present invention proposes a drawing 1 which can improve the relative variation of the low capacitance coupling, which can improve the aperture ratio of the conventional compensation capacitor, and can solve the above problem.

The pole is relatively located above the extension: the first and the compensation capacitor are between the attack pole and the extension . In addition, the: pixel structure further comprises a halogen electrode and a storage capacitor electrode ~ the halogen electrode is connected to the drain electrode. The storage capacitor electrode is set at the thickness of the 2 pole, and the brittle electrode extends through the pixel electrode. To the storage capacitor, a second compensation compensation capacitor between the pole and the storage capacitor electrode and the extension of the capacitor body and the extension thereof form a change in capacitance caused by the offset of the element to reduce the 098208393 form No. Aloi 0982027206-0 Page 5 of 17 M366088 The effect of the amount of change in low parasitic capacitance on the wheel-in voltage and the effect of the compensation capacitor on the aperture ratio.

As shown, the pixel structure of the present invention includes a scan line 32, a data line 34 and a thin film transistor 36. The thin film transistor 36 includes a gate 361, a source 362 and a drain 363. . The scan line 32 has an extension 322 at a relative position of the thin film transistor 36. The gate 361 is located on the scan line 32, the source 362 is coupled to the data line 34, and the source 362 is oppositely located on the scan line 32. 3 6 3 is located on the extension 3 2 2 , and since the pole 3 36 is relatively located on the extension 3 2 2 , there is a first compensation capacitor CC1 between the drain 3 6 3 and the extension 322. Further, the width of the extension region 322 corresponding to the first compensation capacitor CC1 is greater than the width of the gate 363 corresponding to the first compensation valley CC1. The general scan line 32. and the data line 34 are selected from conductive materials such as chrome, gold, silver, imprint, lock, smash, etc., and the source 362 and the drain 363 of the thin film transistor 36 are also selected from Conductive material. In addition, the pixel structure 30 of the present invention further includes a pixel electrode 38 and a storage capacitor electrode 40; wherein the pixel electrode 38 is adjacent to the scan line 32 and the data line 34, and the thin film transistor 36 is coupled via the drain 363. Connected to the halogen electrode 38, the drain 363 and the pixel electrode 38 have a through hole 364, the drain 363 is electrically connected to the pixel electrode 38, and the pixel electrode 38 is selected from the transparent guide 098208393.

Thus, a second compensation capacitor CC2 is formed between the drain 363 and the storage capacitor electrode 4 to further compensate for the parasitic capacitance. In the present creation, the first compensation capacitor CC1 is the corresponding parasitic electric energy eCgd, and the second compensation capacitance CC2 is the corresponding parasitic capacitance Cst, so the capacitive coupling function based on the influence of the input voltage is ((Vgh_Vgl) xCgs) / (
