Abstract

The invention discloses a GIP circuit for improving display quality and a driving method. The driving method comprises the following steps: a grid signal G (n-4) is written into a high potential from a t1 moment to a t2 moment, and is written into a low potential at other moments; the clock signal CKn is written into a high potential from the t1 moment to the t2 moment and after the t6 moment, and the clock signal CKn is written into a low potential at other moments; the clock signal CK (n + 4) is written into a high potential from the t1 moment to the t2 moment, the high potential is firstly written into the clock signal CK (n + 4) at the t5 moment and the t6 moment and then is written into a low potential, and the low potential is written into the clock signal CK (n + 4) at other moments; the grid signal G (n) is written into a high potential from the t3 moment to the t4 moment, and is written into a low potential at other moments; and the grid signal G (n + 4) is written into a high potential and then is written into a low potential at the t5 moment and the t6 moment. According to the technical scheme, the voltage of the Q point is suppressed by introducing the Qb node, so that the discharge path of the Q point does not directly pass through the voltage signal VGL, and the attenuation of the voltage of the Q point is effectively avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a GIP circuit and a driving method for improving display quality. Background technique [0002] In order to reduce the manufacturing cost of the display panel and achieve a narrow frame, GIP (Gatein Panel, door panel) technology is usually used in the manufacturing process to integrate the gate circuit (ie, the GIP circuit) on the flat display panel. [0003] For TFT-LCD display panels, the stability of the GIP circuit is very important, and it directly affects whether the picture can be displayed normally. Among them, TFT is the abbreviation of Thin Film Transistor, Chinese is thin film transistor, LCD is the abbreviation of Liquid Crystal Display, Chinese is liquid crystal display. [0004] Due to the influence of the manufacturing process, the threshold voltage of the transistor of the GIP circuit may be less than 0, which affects the stability of the GIP circuit, such as th...
