Patent number: 10861367Abstract: According to a drive method for the display panel, m multiplex signals sequentially generate the high level pulse at the beginning of the (2i?1)th row period in a predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i?1)th row period continues until the end of the (2i?1)th row period. The m multiplex signals sequentially generate the high level pulse at the beginning of the (2i)th row period in a reverse order to the predetermined order. The high level pulse of the multiplex signal that is the last one to generate the high level pulse in the (2i)th row period continues until the end of the 2i row period. As a result, the number of times that the levels of the multiplex signals are changed in a frame period can be decreased to reduce the power consumption.Type: GrantFiled: December 19, 2018Date of Patent: December 8, 2020Inventors: Lihua Zheng, Mang Zhao, Yong Tian
