Touch display apparatus

Abstract

The invention provides a touch display apparatus. The touch display apparatus has a display region and a bezel region. The touch display apparatus comprises a substrate, a display function layer and a film packaging layer arranged in sequence and a touch electrode layer, wherein the display function layer is arranged in the display region; the touch electrode layer is located on one side, far away from the substrate, of the display function layer; the bezel region comprises a climbing region; the climbing region is next to the display region; in a direction far away from the display region, the thickness, corresponding to the climbing region, of the touch display apparatus is gradually reduced; the touch electrode layer comprises touch electrodes; the touch electrodes are grid-shaped metal wires; and the grid density of the touch electrodes located in the climbing region is greater than the grid density of the touch electrodes located in the display region. According to the touch display apparatus provided by the invention, a touch signal intensity difference value of the display region and the bezel region is reduced, so that the touch sensitivity of the edge of the display region of the touch display apparatus is enhanced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (liquid crystal display, liquid crystal display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also It has the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and is increasingly used in various high-performance display fields. [0003] Setting the touch electrodes in the OLED as grid-like metal traces can reduce the impedance of the touch electrodes and improve touch sensitivity on the one hand. On the other hand, since the touch electrodes are grid-like metal traces, the grid-like The ductility of the metal traces is good, and the bending re...

AI Technical Summary

Problems solved by technology

However, due to the different thicknesses of the display panels in the frame area and the display area, the touch signal strength between the touch electrodes formed by the grid-shaped metal traces in the frame area and the touch subject (such as a finger) is higher than that of the grid-shaped metal traces in the display area. The touch signal strength between the touch electrodes composed of wires and the touch body is weak, and the touch electrodes at the edge of the display area are at least partially located in the frame area, so the touch sensitivity at the edge of the display area of ​​the touch display device is poor.
