  • Display apparatus and a method of operating the same
    Patent number: 10157567
    Abstract: A display apparatus includes a display panel, a gate driver, and a gate driving control circuit. The gate driver is connected to the display panel, and generates gate signals for driving the display panel using a gate clock signal. The gate driving control circuit generates the gate clock signal using a gate on voltage and a gate off voltage, determines whether an operation environment is an abnormal temperature environment by comparing a first feedback gate signal with a second feedback gate signal, and adjusts a voltage level of the gate clock signal in the abnormal temperature environment. The first feedback gate signal is retrieved from the display panel while a first frame image is displayed on the display panel. The second feedback gate signal is retrieved from the display panel while a second frame image subsequent to the first frame image is displayed on the display panel.

    Patent number: 10152938
    Abstract: A display panel is divided into multiple areas respectively driven by multiple drivers, and the multiple areas are adjacent to each other along a first direction. An object moves along the first direction between a first frame and a second frame and is displayed on the display panel. The moving speed of the object is compared with a reference speed. A main compensation frame is added between the first frame and the second frame. A first high speed compensation frame is added between the first frame and the main compensation frame when the moving speed is higher than or equal to the reference speed. A first low speed compensation frame is added between the first frame and the main compensation frame when the moving speed is lower than the reference speed, and the first low speed compensation frame is different from the first high speed compensation frame.
