Abstract

The invention provides a GIP detection circuit and a flat display device. A high level and a low level are coupled to a detection end through a sixth transistor and a seventh transistor respectively to eliminate the noise of the detection end. Therefore, the test effect of the GIP detection circuit is improved.

Description

technical field [0001] The invention relates to the technical field of flat panel display, in particular to a GIP detection circuit and a flat panel display device. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communication and information home appliances, people's dependence on electronic products is increasing day by day, which brings about the vigorous development of various display technologies and display devices. The flat panel display device has the characteristics of complete planarization, lightness, thinness, power saving, etc., and thus has been widely used. [0003] At present, in order to reduce the manufacturing cost of flat-panel display devices and achieve narrow borders, GIP (Gate in Panel) technology is usually used in the manufacturing process to directly integrate gate drive circuits (ie, GIP circuits) into flat-panel display devices. panel. The GIP circuit generates...
