a gate chip

Abstract

The invention discloses a gate chip, which can avoid the abnormal output of the gate chip caused when the external input signal input to the gate chip is in a floating state, ensure that the gate chip is in a normal state after power-on, and avoid high voltage after power-on. A large current phenomenon occurs in the flat signal, which effectively protects the gate chip.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to a gate chip. Background technique [0002] Liquid crystal panels are popular because of their small size, light weight, and superior display quality. The circuit driving system of the LCD panel generally includes a timing controller (TCON), a driver chip (Driver IC), a power manager (PWN) and a programmable gamma correction buffer circuit (P-Gamma IC). The timing controller outputs video signals to The driver chip, the power manager output voltage to the driver chip and programmable gamma correction buffer circuit. The driving chip further includes a gate chip (Gate IC) for providing row scanning signals to the liquid crystal panel and a source chip (Source IC) for providing data signals to the liquid crystal panel. [0003] refer to Figure 1A and Figure 1B , Figure 1A is the structure diagram of the existing gate chip, Figure 1B for Figure 1A The working t...
