Embodiment Construction
[0065] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0066] figure 1 It is a plan view of the first embodiment of the TFT-LCD array substrate of the present invention, reflecting the structure of a pixel unit, figure 2 for figure 1 The cross-sectional view of A1-A1 in the middle, image 3 for figure 1 Sectional view of B1-B1 direction in the middle. Such as Figure 1 ~ Figure 3 As shown, the TFT-LCD array substrate of this embodiment is a structure formed by four patterning processes. The main structure includes the first gate line 11a, the second gate line 11b, the data line 12, and the pixel electrode formed on the substrate 1. 9. The first thin film transistor and the second thin film transistor, the first gate line 11a and the second gate line 11b arranged in parallel and two adjacent data lines 12 define a pixel area, the first thin film transistor, the second...

The invention relates to a TFT-LCD (Thin Film Transistor Liquid Crystal Display) array substrate and a manufacturing method thereof. The array substrate comprises a first grid line, a second grid line and a data line which are formed on the substrate and used for limiting a pixel region, a pixel electrode, a first thin film transistor and a second thin film transistor are formed in the pixel region, and the first thin film transistor and the second thin film transistor are provided with same parasitic capacitors. When the first grid line supplies a starting voltage to the first thin film transistor, the second grid line supplies a first voltage to the second thin film transistor. When the first grid line supplies a shutdown voltage to the first thin film transistor, the second grid line supplies a second voltage to the second thin film transistor, and the difference between the starting voltage and the shutdown voltage equals to the difference between the second voltage and the first voltage. Because two grid lines and two thin film transistors are adopted and the parasitic capacitors of the two thin film transistors are the same, the variation of electric charges stored by the two parasitic capacitors are equal in quantity and opposite in sign when the charging is completed. Thus, the charge variation amount on the pixel electrode is 0, and the leaping voltage of the pixel electrode is effectively eliminated.
Description
technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. TFT-LCD is mainly composed of an array substrate and a color filter substrate in a box, wherein gate lines, data lines, pixel electrodes and thin film transistors are formed on the array substrate, and each pixel electrode is controlled by a thin film transistor. When the thin film transistor is turned on, the pixel electrode is charged during the turn-on time, and after the thin film transistor is turned off, the voltage of the pixel electrode will be maintained until recharging in the next scan. [0003] For the single-gat...
