Patent number: 10008171Abstract: A gate driving circuit is provided. The gate driving circuit includes multistage driving modules, where an Nth stage driving module includes a setting circuit, a first driving circuit, an isolating switch circuit, a second driving circuit and an anti-noise circuit. The setting circuit generates a first precharge signal according to a gate driving signal of an (N?2)th scan line or a start signal. The isolating switch circuit coupled between the first driving circuit and the second driving circuit provides a second precharge signal, so as to effectively avoid a flickering problem of a display image caused by a surge of the gate driving signal due to a coupling effect of a parasitic capacitance of the transistor and a bootstrap capacitor, and meanwhile the bootstrap capacitor is not used, so as to effectively reduce a bezel area.Type: GrantFiled: October 27, 2016Date of Patent: June 26, 2018Assignees: Chunghwa Picture Tubes, Ltd., National Chiao Tung UniversityInventors: Wei-Lien Sung, Han-Lung Liu, Wen-Chuan Wang, Chi-Liang Kuo, Yuan-Hao Chang, Wen-Che Wang, Po-Tsun Liu, Guang-Ting Zheng, Yu-Fan Tu
