Description
Technical Field
The invention relates to the technical field of display, in particular to a touch module and a display device.
Background
The existing display device technology mainly comprises a liquid crystal display, a plasma display device, organic electroluminescence and active matrix organic electroluminescence, and has wide application space in vehicle-mounted, mobile phones, flat computers, computers and television products.
Generally, touch control has become one of the standard of many display devices, wherein capacitive touch screens are widely used, and the basic principle is to use tools such as a finger or a stylus to generate capacitance with the touch screen, and to use an electric signal formed by capacitance change before and after touch to confirm whether the panel is touched and confirm touch coordinates.
The touch panel is generally formed by combining a display device such as an organic light emitting diode display device (OLED) or a Liquid Crystal Display (LCD) with the touch panel. Touch panels are widely used in consumer electronics such as cell phones, tablets, and vehicle-mounted displays, as well as in industrial equipment terminals.
The touch pad includes a touch pattern for generally matrix form and touch electrode traces for connection to the touch IC. When the touch pad is fabricated on the display device, the touch pattern and the touch signal may be located on the same metal layer, or may be formed by metal wirings of different layers. When the touch pattern and the touch electrode trace are composed of different layers of metal traces, the middle is generally separated by an insulating layer. Meanwhile, the touch pattern and the touch electrode wiring generally need to avoid the pixel luminous area when in design, so that the display effect of the panel is not affected.
When the touch pattern and the touch electrode trace are formed by different layers of metal traces, the shape design and distribution of the touch pattern and the touch electrode trace in the non-pixel light emitting area need to be considered. On the touch panel, when the touch electrode and the touch electrode trace are located in different layers, the following touch panel design manner of fig. 1 is generally adopted. As shown in fig. 1, in a conventional touch panel 90, the touch electrodes 91 are schematically arranged in an array, and the touch electrodes 91 and the touch electrode traces 92 connected with the touch electrodes are connected by punching an insulating layer therebetween. When the touch electrode trace 92 passes through other touch electrodes 91, it is assumed that the touch electrode 91 and the touch electrode trace 92 are simply designed to overlap with each other with equal line widths, and when foreign matters appear in the packaging layer of the pixel light emitting layer or in the insulating layer separating the touch electrode 91 and the touch electrode trace 92 in the process, the touch electrode 91 and the touch electrode trace 92 are easy to be shorted. The short circuit greatly affects touch performance, resulting in a touch panel that cannot accurately respond to a touch location.
