Abstract: A display device includes a display panel including a first and a second non-display area, a main active area, and a sub active area, wherein the active areas each include a matrix of sub-pixels; a data driver in the first non-display area to provide image data to the matrices of sub-pixels; a main gate driver in the second non-display area to provide a corresponding gate signal to each sub-pixel in the main active area; a sub gate driver in the second non-display area to provide a corresponding gate signal to each sub-pixel in the sub active area; an auto-probe test pad in the non-display area for transmitting a first start signal received from an auto-probe signal generating device to one of the main gate driver and the sub gate driver while testing the display panel; and a signal transmission circuit connecting the main gate driver and the sub gate driver.

Abstract: An organic light emitting display device can include an organic light emitting diode (OLED), a driving transistor connected to an anode electrode of the OLED, a scan transistor, a digital-to-analog converter (DAC) and a sensing unit. The scan transistor is connected the anode electrode of the OLED and a data line. The DAC supplies a data voltage for displaying to the data line in a displaying period and supplies a data voltage for sensing to the data line in a sensing period. The sensing unit obtains an anode voltage of the OLED as a sensing voltage through the data line in the sensing period.

Abstract: A display panel having a touch sensor includes a pixel array, touch sensor blocks, a touch inspection pad unit, and an image inspection pad unit. In the pixel array, a plurality of pixels is disposed in a matrix form. The touch sensor blocks are connected to respective pluralities of the pixels in the pixel array. The touch inspection pad unit divides the touch sensor blocks into odd-numbered touch sensor blocks and even-numbered touch sensor blocks and a first touch inspection pad is coupled to the odd-numbered touch sensor blocks, while a second touch inspection pad is coupled to the odd-numbered touch sensor blocks. The image inspection pad part is commonly coupled to the odd-numbered touch sensor blocks and the even-numbered touch sensor blocks.

Abstract: An array substrate for a liquid crystal display includes a substrate and first and second subpixels which are positioned on the substrate and are defined by a crossing structure of one gate line, a first data line, a second data line, a first common line, and a second common line. The first subpixel includes a first semiconductor layer, a first source electrode, a first drain electrode, and a first pixel electrode connected to the first drain electrode. The second subpixel includes a second semiconductor layer, a second source electrode, a second drain electrode, and a second pixel electrode connected to the second drain electrode. The first and second subpixels share the one gate line with each other, and the first drain electrode and the second drain electrode are exposed through one contact hole.
