Abstract: A display includes a display panel and at least one display driver chip. The display panel includes a display area and a non-display area surrounding the display area. The display area includes a planar area and a curved bending area located on at least one side of the planar area, where a longitudinal direction of each data signal line is perpendicular to a longitudinal direction of the side of the planar area on which the curved bending area is arranged, and each data signal line extends to a non-display area on the side of the curved bending area of the display area. The display driver chip is connected to data signal lines by using a chip-on-film, and the display driver chip is located in concave space.

Abstract: A display apparatus including a plurality of pixel circuit rows, where each pixel circuit row includes a plurality of pixel circuits, and each pixel circuit includes a light emitting component and a driving circuit. A gate voltage generation circuit generates a plurality of scan signals. A first scan signal and a second scan signal respectively control write circuits in driving circuits in a first pixel circuit row and a second pixel circuit row. The write circuit adjusts, based on a data voltage for controlling luminance of a light emitting component, a voltage at one end of a storage capacitor to a first voltage. The first scan signal further controls a reset circuit in a driving circuit in a second pixel circuit row, and the reset circuit resets the voltage at one end of the storage capacitor to a second voltage based on a reference voltage.

Abstract: A display stack with millimeter-wave antenna functionality comprising a plurality of adjoining layers, the layers comprising at least a cover layer, a touch sensor panel layer comprising a touch sensor arrangement, and a display panel layer. The touch sensor panel layer comprises a first sensor line grid pattern and a second sensor line grid pattern, the first sensor line grid pattern comprising a plurality of continuous first sensor lines, the second sensor line grid pattern comprising a plurality of continuous second sensor lines. At least a part of the first sensor lines and the second sensor lines are configured to function as radiators for the millimeter wave antenna functionality. This allows providing the millimeter wave antenna in the touch sensor panel structure without the antenna and the touch sensor panel interfering with each other.
