Patent number: 11984064Abstract: A display apparatus having a wide range of threshold voltage compensation function is provided. In the display apparatus, a p-channel transistor is used as a driving transistor of the light-emitting device. Discharging is performed through a source-drain path while constant voltage is supplied to a gate so that Vth is extracted between the gate and the source. In addition, when a drain potential is set to the sum of forward voltage and a cathode potential of the light-emitting device or a potential sufficiently lower than the sum, it is possible to continue the discharging even when Vth is positive voltage. That is, compensation can be performed even in the case where Vth variation occurs from positive voltage to negative voltage.Type: GrantFiled: July 30, 2021Date of Patent: May 14, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Susumu Kawashima, Koji Kusunoki, Kazunori Watanabe, Satoshi Yoshimoto

Publication number: 20240144879Abstract: Provided is a highly reliable semiconductor device. The present invention relates to a shift register circuit including a plurality of stages of sequential circuits. An output signal of a sequential circuit is input to a sequential circuit in the subsequent stage. Before a sequential circuit outputs a signal and after the sequential circuit outputs the signal, the potential of a gate of a transistor included in the sequential circuit is changed in accordance with a clock signal so as to avoid voltage stress application between the gate and a source of the transistor for a long time. The shift register circuit can be applied to a scan line driver circuit of a display apparatus, for example.Type: ApplicationFiled: February 22, 2022Publication date: May 2, 2024Inventors: Satoshi YOSHIMOTO, Susumu KAWASHIMA, Kazunori WATANABE, Tomoaki ATSUMI, Koji KUSUNOKI
