Cutting-angle signal generating circuit

Abstract

The invention relates to a cutting-angle signal generating circuit which comprises a signal output part, a first switch, a second switch, a third switch, a first control unit, a second control unit and a resistor. The signal output part is electrically connected with the first switch, the second switch and the third switch. The first switch is electrically connected with a first voltage source and starts up according to a frequency signal. The second switch is electrically connected with a second voltage source. The inversion frequency signal of the first control unit is a reversed-phase frequency signal for outputting a switching signal capable of swtiching on the second switch. The resistor is connected in series between a third voltage source and the third switch. The third switch controls the signal output part to be conducted with the third voltage source electrically. The third switch is switched on by the second control unit according to the reversed-phase frequency signal and the switching signal.

Description

technical field [0001] The present invention relates to a circuit capable of generating electrical signals, and in particular to a shading signal generating circuit. Background technique [0002] Today's Thin-Film Transistor Liquid Crystal Display (TFT LCD) mostly uses multiple transistors to control the arrangement of liquid crystal molecules, and in this type of LCD, the transistor array substrate (transistor array substrate) is indispensable The missing important components, wherein the transistor array substrate usually includes multiple pixel units (pixel unit), multiple scan lines (scan line) and multiple data lines (data line). The pixel units are electrically connected to the scan lines and the data lines, and each pixel unit generally includes a transistor and a pixel electrode electrically connected to the transistor, wherein the scan lines and the data lines are electrically connected to the transistors. Each scanning line can transmit a gate signal (gate sign...

However, affected by capacitive coupling effects and loads, the feedthrough voltages generated by these pixel units are not consistent

Generally speaking, there is a large gap between the feed-through voltage of the pixel unit close to the gate driving component and the pixel unit far away from the gate driving component, and this will cause flicker on the screen.
