Abstract: A liquid crystal display apparatus includes a display panel, a light source module configured to provide light to the display panel, a receiving container receiving the light source module therein, and an adhesion member disposed between the display panel and the receiving container to couple the display panel to the receiving container. The adhesion member includes a base layer with a hollow pocket therein and an adhesion layer disposed on both surface of the base layer. When the display panel is deformed, the adhesion member conforms thereto. Thus, light-leakage of the display panel may be prevented and light characteristics of the liquid crystal display apparatus may be improved.

Abstract: A display device includes a display panel including a plurality of pixels, a controller configured to output image data and a gated clock signal, the image data including a plurality of pixel data for the plurality of pixels, and a data driver configured to receive the image data and the gated clock signal from the controller, and to sample the image data in response to the gated clock signal. The controller detects a repeated data pattern where same pixel data is repeated in the image data, generates a clock enable signal having an off level in a period in which the repeated data pattern is transferred, and gates an input clock signal in response to the clock enable signal to produce the gated clock signal.

Abstract: A display apparatus includes a printed circuit board (PCB). A power management integrated circuit (PMIC) is mounted on the PCB and is configured to generate first to fourth gate clock signals and first to fourth inversion gate clock signals. A phase of the first gate clock signal partially overlaps a phase of the second to fourth gate clock signal. Each of the first to fourth inversion gate clock signals has a phase opposite to that of a respective one of the first to fourth gate clock signals. A gate driver generates a plurality of gate signals based on the first to fourth gate clock signals and the first to fourth inversion gate clock signals and applies the plurality of gate signals to a plurality of gate lines. A display panel is connected to the plurality of gate lines.
