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: 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.
