Abstract: An in-plane switching (IPS) mode liquid crystal display (LCD) device includes a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer between the first and second substrates; a second polarizer on an outer surface of the second substrate, the second polarizer having a second polarizing element; and an in-cell retarder on an inner surface of the second substrate, wherein the in-cell retarder compensates a light leakage in a front direction of the liquid crystal display panel.

Abstract: An organic light emitting display device and a method of repairing the device are discussed. According to an embodiment, the device includes a display panel having pixels, each including an OLED in every pixel area defined as scan and data lines intersect with each other and having a repair structure in at least one of horizontal and vertical directions between adjacent pixels by one or more repair lines; a timing controller configured to generate compensation data when a dark spot is generated in one of the plurality of pixels of the display panel, and adjust a magnitude of image data according to the compensation data; and a data driver configured to adjust a magnitude of a data voltage according to the image data adjusted in magnitude, and output the data voltage adjusted in magnitude to the data lines.

Abstract: By forming a repair structure in a horizontal direction and vertical direction by using one or more repair lines between two or more pixels adjacent to each other in a display panel, even though a dark spot appears due to a defective operation of one pixel, the one pixel may be compensated to be driven by using the other pixel.

Abstract: A display device including a substrate having a display area and a non-display area. The non-display area is outside of the display area. A plurality of drivers on the non-display area of the substrate. Each of the drivers having a first alignment mark on a first side of the driver and a second alignment mark on a second side of the driver. A first contact pad having a third alignment mark on a first portion of the non-display area of the substrate. A second contact pad having a fourth alignment mark on a second portion of the non-display area of the substrate. The third alignment mark of the first contact pad corresponds to the first alignment mark of the driver and the fourth alignment mark of the second contact pad corresponds to the second alignment mark of the driver.

Abstract: Disclosed are an organic light emitting display capable of preventing lowering of brightness and prolonging its a lifespan, and a driving method thereof. The organic light emitting display controls a level of a gate signal, by outputting a gate high voltage after controlling a level of the gate high voltage, according to a level of a threshold voltage sensed from each pixel of a display panel.
