Abstract

The invention relates to a GIP (gate in panel) signal detection circuit, a GIP signal detection method and a panel display device. The GIP signal detection circuit comprises a signal testing wire, a clock signal line, a first thin film transistor and multiple second thin film transistors, wherein the first thin film transistor is connected between the clock signal line and the signal testing wire, and a grid of the first thin film transistor is connected with the signal testing wire; the signal testing wire is used for receiving multistage GIP signals respectively through the multiple second thin film transistors and outputting testing signals according to the multistage GIP signals. According to the GIP signal detection circuit, the GIP signal detection method and the panel display device, the novel GIP signal detection circuit is adopted, all that is required is one signal testing wire, each stage of GIP signal can be detected, and accordingly, the panel display device guarantees the reliability of the GIP circuit on the basis that the wire is not increased basically.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a GIP signal detection circuit, a GIP signal detection method 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 devi...
