The demultiplexer includes input channels each provided with switching transistors and fanout lines. Each fanout line is correspondingly connected to one data line by one switching transistor to provide one data signal to the one data line. The one switching transistor corresponding to each input channel is controlled by a same control signal. While each gate line scans one row of the sub-pixels, when a rising edge of the control signal reaches an amplitude, and at a moment when the one switching transistor is controlled by the control signal to be on, the demultiplexer is configured to make a difference between a potential reached by a rising edge of one fanout line correspondingly connected to the one data line and a potential of the one data line to be less than a preset threshold.Type: ApplicationFiled: November 26, 2024Publication date: March 13, 2025Applicant: Wuhan China Star Optoelectronics Technology Co., Ltd.Inventors: Jian TAO, Shuai FENG, Yafeng LI, Zhong PENG, Jian HE
