Description

touch display panel

technical field

The present invention relates to a display panel, and particularly to a touch display panel.

Background technique

In recent years, touch panels have been widely used in various electronic products, such as: global positioning system (GPS), personal digital assistant (PDA), cellular phone and palmtop Computer (Hand-held PC), etc., to replace traditional input devices (such as: keyboard and mouse, etc.). This substantial change in design not only enhances the human-machine interface compatibility of these electronic devices, but also frees up more space for installing larger-sized display panels by omitting traditional input devices, which is convenient for users to browse material.

Looking at the existing touch panels, there are resistive, capacitive, sonic and optical. Under the principle of various major projects, many different types of production methods have been derived. For example, resistive type has 8-wire, 7-wire, 6-wire, 5-wire, 4-wire type, digital resistance, etc.; capacitive type has projection type. Type capacitance, surface capacitance, digital capacitance (multi-touch capacitance type), etc.; optical type includes infrared shielding type, total reflection suppression type, etc. The projected capacitive touch screen confirms whether there is touch by detecting the coupling capacitance between the driving electrode and the receiving electrode. Projected capacitive touch screens are generally classified into two types, one is a double-layer conductive layer, such as double-layer indium tin oxide (DITO), and the other is a single-layer conductive layer, such as single-layer indium tin oxide (SITO). For the DITO structure, the specific implementation structure can be shown in FIG. 1 . The projected capacitive touch screen includes a first transparent substrate 10 , a second transparent substrate 12 , a receiving electrode layer 14 , a driving electrode layer 16 , a The transparent optical adhesive layer 18 and a cover plate 20, wherein the first transparent substrate 10, the driving electrode layer 16, the transparent optical adhesive layer 18, the second transparent substrate 12, the receiving electrode layer 14 and the cover plate 20 are sequentially stacked from bottom to top . The first transparent substrate 10 has a sensing area and a frame area around it. The driving electrode layer 16 includes a plurality of electrode series and a plurality of wirings. The electrode series are located on the sensing area and the wirings are located on the frame area. Similarly, the second transparent substrate 12 has a sensing area and a frame area around it. The receiving electrode layer 14 includes a plurality of electrode series and a plurality of wirings. The electrode series are located in the sensing area and the wirings are located on the frame area. However, in this structure, the lines are all designed on the same plane, which makes it increasingly difficult to reduce the line width and line spacing. In order to achieve a narrow frame, there is currently a technology to bend the electrode layer to meet the needs of customers with ultra-narrow frame, but this will expose the electrode layer and easily damage the electrode layer.

Therefore, the present invention proposes a touch display panel to solve the problems caused by the prior art in view of the above-mentioned problems.
