Description

touch display panel

technical field

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

Background technique

In recent years, touch panels (Touch Panel) have been widely used in various electronic products, such as: Global Positioning System (GPS), Personal Digital Assistant (PDA), mobile phone (cellular phone) and handheld Computer (Hand-held PC), etc., to replace traditional input devices (such as: keyboard and mouse, etc.). This significant change in design not only improves the human-machine interface affinity of these electronic devices, but also frees up more space for installing larger-sized display panels because of the omission of traditional input devices, which is convenient for users to browse material.

Looking at the existing touch panels, there are resistive, capacitive, acoustic and optical touch panels. Under the principles of various large projects, many different types of production methods have been derived. For example, resistive type has 8 wires, 7 wires, 6 wires, 5 wires, 4 wires, digital resistors, etc.; capacitive type has projection Type capacitance, surface capacitance, digital capacitance (multi-touch capacitive type), etc.; optical type includes infrared shielding type, suppression total reflection type, etc. The projected capacitive touch screen confirms whether there is a touch by detecting the coupling capacitance between the driving electrode and the receiving electrode. There are generally two types of projected capacitive touch screens. 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, its specific implementation structure can be shown in Figure 1. This 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 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 stacked in sequence from bottom to top .

However, in this structure, the traces are all designed on the same plane, making it increasingly difficult to reduce the line width and pitch. 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 frames, but this will cause the oxidation of the lines on the bent area to extend from the outside to the inside.

Therefore, the present invention proposes a touch display panel to solve the problems caused by the prior art.
