  • TFT array substrate and display device including the same
    Patent number: 10998343
    Abstract: A thin-film transistor (TFT) array substrate is provided. The TFT array substrate includes a base substrate, a semiconductor layer disposed on the base substrate, an insulating layer disposed on the semiconductor layer, and a gate electrode disposed on the insulating layer. A top surface of a portion of the insulating layer overlapping the semiconductor layer in a plan view of the base substrate and a top surface of the gate electrode are placed on the same level.
    Type: Grant
    Filed: October 3, 2019
    Date of Patent: May 4, 2021
    Assignee: SAMSUNG DISPLAY CO., LTD.

  • Pixel and organic light emitting display device using the same
    Patent number: 10339862
    Abstract: A pixel includes a first transistor, a second transistor, a third transistor, and a capacitor. The first transistor connects a first power source to a light emitter based on a first control signal. The second transistor connects a pixel circuit to the light emitter. The third transistor connects a second power source to the pixel circuit based on a second control signal. The capacitor is a MOS capacitor having a first electrode connected to receive the second control signal and a second electrode connected to the second transistor.
