Problems solved by technology
However, in the prior art, due to the large in-plane load of the display device using integrated gate drive with a large display area, the display device is generally driven by the double-terminal hedge method of integrated gate drive, because the two active regions of the display device It is difficult to make the line width and film thickness of the signal bus on the side completely consistent, resulting in differences in the loads of the left and right signal buses, and the waveforms of the clock signal CLK transmitted along the signal bus and the scan start and end signal STV at the end of the signal bus are distorted The degree of distortion at the ends of the signal bus on both sides of the source area is different, resulting in uneven charging of the pixels at the corners of the display screen, and display differences at the four corners of the active area, affecting the user's visual experience

The invention discloses a display device, a drive circuit, and a preparation method for the drive circuit. The drive circuit comprises a control module which is used for providing a control signal; a plurality of first signal buses and a plurality of second signal buses, which are used for transmitting control signals; a plurality of grid lines; a plurality of first drive units, wherein each first drive unit is connected with some first signal buses through lead wires, and provides a first drive signal for the corresponding grid line according to a control signal; a plurality of second drive units, wherein each second drive unit is connected with some second signal buses through lead wires, and provides a second drive signal for the corresponding grid line according to the control signal, and some first signal buses are connected with some corresponding second signal buses. The corresponding signal buses of different groups of signal buses in the drive circuit are connected through routing lines, and the drive circuit can improve the uniform charging and display difference of pixels of an active region of the display device, and improves the user experience.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device, a driving circuit and a preparation method thereof. Background technique [0002] With the development of thin film transistor liquid crystal display (TFT LCD) industry, the competition of TFT LCD products is becoming increasingly fierce, and all manufacturers are adopting new technologies to reduce the cost of products, thereby improving the market share of their products. competitiveness. [0003] The gate (Gate) circuit of the traditional TFT LCD panel uses wiring to import signals from the driver chip (IC) to turn on the TFT, and input the display signal to the pixel unit to complete the screen display. Since each wiring corresponds to a row of gate circuits, the number of wiring lines is large and the space occupied is relatively large. In response to market demand for high-resolution and high-resolution products with narrow borders, int...
