Abstract

The invention discloses a GIP circuit. The output end of T1 is connected with Qb; the input end of T2 is connected with Qb; the output end of T2 is connected with Q; the output end of T3 is connected with the P; the control end T4 is connected with Q; the input end of T5 is connected with P, and the control end of T5 is connected with Q; the input end of T6 is connected with Q, the output end of T6 is connected with Qb, and the control end of T6 is connected with P; the input end of T7 is connected with Qb, and the control end of T7 is connected with P; the input end of T8 is connected with P; the input end of T9 is connected with Q, and the output end of T9 is connected with Qb; the input end of T10 is connected with Qb; the control end if T11 is connected with P; the input end of T12 is connected with Q, and the output end of T12 is connected with Qb; the input end of T13 is connected with Qb; the input end of T15 is connected with P; and one polar plate of C1 is connected with Q. According to the technical scheme, the potential of the Q point is improved, so the potential drop of the voltage of the Q point due to electric leakage caused by negative threshold voltage of the transistor is avoided, the output waveform of the GIP is not distorted, and the display effect of the display screen is optimized.

Description

technical field [0001] The invention relates to the field of LCD display screens, in particular to a GIP circuit and a driving method thereof. Background technique [0002] For the display screen, the waveform transmission of the GIP circuit is very important, and it is related to whether the pixels in the plane can work normally. In fact, due to uncontrollable factors in the manufacturing process, the transistor threshold voltage of the GIP circuit may be less than 0, which will have a negative impact on the waveform output of the GIP circuit, resulting in abnormal operation of the pixels in the plane and reducing the display quality. Contents of the invention [0003] Therefore, it is necessary to provide a GIP circuit and its driving method to overcome the abnormal waveform transmission caused by the negative threshold voltage bias caused by process factors, so as to improve the display effect of the display screen. [0004] This application provides a GIP circuit, inc...
