摘要： A method for driving a display device including a display panel including a first and a second display area each of which is divided into a plurality of display blocks and n touch blocks comprises a first and a second step. The first step drives the respective display blocks of the first display area sequentially, drives at least one touch block after driving the display blocks, and generates a first touch report after driving all of the n touch blocks. The second step drives the respective display blocks of the second display area sequentially, drives at least one touch block after driving the display blocks, and generates a second touch report after driving the n touch blocks again. The first and the second step are processed within one frame period, and the one frame period includes a vertical blanking interval void of input image data.

摘要： Disclosed are a display panel in which a unit pixel is divided into a wide-angle area and a narrow-angle area in which at least sub-pixel is disposed and light emission is individually and selectively performed, a display device including the same, and a manufacturing method thereof. A semi-cylindrical lens is disposed in the wide-angle area so as to cover a plurality of sub-pixels. Semi-spherical lenses are disposed in the narrow-angle area so as to cover sub-pixels respectively. Therefore, a direction of light emitting from a light-emitting layer is controlled by adjusting a refractive index of each of the lenses in the wide-angle area and the narrow-angle area. Thus, a viewing angle is controlled.

摘要： The present disclosure relates to a touch display panel capable of significantly reducing a number of touch channels provided in a touch display panel in related art and a touch display device including the touch display panel. To this end, the touch display panel according to the present disclosure includes a plurality of touch blocks with a plurality of touch electrodes arranged in a row direction and a plurality of touch lines arranged in a column direction and connected to the touch electrodes, and the touch block includes a total of 25 touch electrodes and nine touch lines. Accordingly, according to the present disclosure, the touch display panel may significantly reduce a number of touch channels and the touch electrodes may be flush with the touch lines.
