Touch display device

Abstract

The invention discloses a touch display device. The touch display device comprises a cover plate, a display panel, a plurality of first touch sensing electrodes, a plurality of first connecting cushions and a first conductive adhering material, wherein the cover plate is defined with a visible area and a peripheral area; the peripheral area is arranged on at least one side of the visible area; the display panel comprises an upper substrate, an array substrate and a display medium; the upper substrate is arranged between the cover plate and the array substrate; the display medium is arranged between the upper substrate and the array substrate; the first touch sensing electrodes are at least arranged in the visible area; the first connecting cushions are arranged in the peripheral area, and electrically connected with the corresponding first touch sensing electrodes; the first conductive adhering material is arranged between the cover plate and the array substrate, and is used for electrically connecting the first connecting cushions and the array substrate.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device which utilizes a conductive adhesive material to electrically connect a touch sensing electrode and an array substrate. Background technique [0002] In recent years, touch sensing technology has developed rapidly, many consumer electronic products such as mobile phone (mobile phone), GPS navigator system (GPS navigator system), tablet PC (tablet PC), personal digital assistant (PDA) and notebook computer ( laptop PC) and so on have launched products combined with touch functions. Among the above-mentioned electronic products, the original display function and the touch sensing function are mainly integrated to form a touch display device. Currently, the mainstream touch display device is an add-on touch display panel formed by bonding a display panel and a touch panel. Touch panels can be roughly divided into two-glass (glass / glass) and single-glass (one...

Problems solved by technology

[0003] With the improvement of the resolution of the touch panel or / and the development of single-layer touch sensing electrodes, the number of connection pads used for electrical connection with external components such as flexible printed circuit boards (flexible printed circuit, FPC) will also increase, resulting in For example, in order to reduce the width of the flexible circuit board, the connection pads may be arranged more closely, which will cause problems such as difficulty in alignment when the touch panel and external components such as the flexible circuit board are subjected to a bonding process (bonding process), and then The production pass rate of the product is affected, and the above-mentioned alignment problem also exists when the connection pad or / and the alignment mark are transparent or difficult to identify
