Patent number: 11783793Abstract: A display panel includes data lines and scanning lines in a display region, and a demultiplexer in a non-display region. The demultiplexer includes m branches. m is an integer. m?2. Each branch includes a switching transistor which includes a first electrode coupled with an input terminal of the demultiplexer, a second electrode coupled with one of the data lines, and a control electrode for receiving a switching control signal. The demultiplexer includes a first demultiplexer including a compensation transistor, of which first and second electrodes are short-circuited. The compensation transistor is coupled with the data line and has a control electrode for receiving a compensation control signal. The compensation control signal received by the compensation transistor in the branch has one functional rising edge in a period during which the scanning line provides an effective level signal once.Type: GrantFiled: October 26, 2022Date of Patent: October 10, 2023Assignee: Xiamen Tianma Micro-Electronics Co., Ltd.Inventors: Yiqiang Lin, Hao Wu, Poping Shen

Publication number: 20220123027Abstract: A display panel and a display apparatus includes sub-pixels, and First and second regions arranged along a first direction. First sub-pixel groups in the first region and second sub-pixel groups in the second region are arranged along the first direction, and each include at least two sub-pixels arranged along the second direction. A number of the sub-pixels in the second sub-pixel group close to the first region is greater than a number of the sub-pixels in the second sub-pixel groups away from the first region. The first sub-region of the second region is closer to the first region than the second sub-region. From the first region to the second region, a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the first sub-region is greater than a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the second sub-region.Type: ApplicationFiled: December 28, 2021Publication date: April 21, 2022Applicant: Xiamen Tianma Micro-Electronics Co., Ltd.Inventors: Kunfeng ZHANG, Yiqiang LIN, Wei WU, Boping SHEN
