Problems solved by technology

In Figure 1b, the GE767 SET and GE769 STV signal lines in the dotted line area are distributed in the circuit board in the above-mentioned through-hole layer jump mode. When there is an abnormal voltage there, it is easy to cause the layer jump to be burned, causing the display device damage

Abstract

The invention discloses a circuit structure and a display device thereof. The display device comprises a liquid crystal panel, a gate in-panel (GIP) circuit, a source driver and a frequency generator. When a set / reset signal of the last-stage shift register of the GIP circuit has an abnormal voltage, the circuit is easily burnt down due to layer skipping, and a bright line is formed on the output of the last-stage gate. By adoption of the circuit structure, a transistor component is added into the set / reset signal, the abnormal voltage resistance of the set / reset signal is improved, and the problem that the circuit is easily burnt down is solved.

Description

technical field [0001] The invention relates to a circuit structure, in particular to a circuit structure with parallel transistors, which is suitable for liquid crystal display panels. Background technique [0002] Referring to Figure 1a, it is a schematic diagram of the connection of the last stage shift register of a known technology on-board gate (gate in panel, GIP) circuit. Figure 1a includes a plurality of shift registers (shift register) electrically coupled in series catch. See Figure 1b, which is the equivalent circuit diagram of Figure 1a. As shown in Figure 1a and Figure 1b, in the known technology, the signal related to the output of the last stage of the shift register signal, that is, the action of the GE767 SET / GE769 STV signal is carried out in conjunction with CLK, CLKB and RESET transfer. When abnormal voltage occurs in the circuit, it is easy to burn out due to many through holes concentrated in the circuit board layer at the GE767 SET / GE769 STV signal...
