Problems solved by technology

However, too many sensing electrodes will increase the number of wires, increase the range of the wiring area, that is, increase the width of the edge of the touch screen panel, and increase the overall size of the touch screen panel, which is not suitable for small and medium-sized electronic devices. Limits widespread use of touch screen panels

specific Embodiment 1

[0016] See figure 1 and figure 2 , the embodiment of the present invention provides a touch screen panel 10 , the touch screen panel 10 includes an insulating substrate 12 , an adhesive layer 13 , a transparent conductive layer 14 , a plurality of sensing electrodes 16 , and a plurality of wires 18 . The plurality of sensing electrodes 16 are arranged at intervals on one side of the transparent conductive layer 14 .

[0017] The touch screen panel 10 defines two areas: a touch area 10A and a wiring area 10B. The touch area 10A is an area where the touch screen panel 10 can be touched to realize a touch function, and the wiring area 10B is an area where a plurality of wires 18 are arranged in the touch screen panel 10 . The wiring area 10B is a small area near the edge of the touch screen panel 10 , which may be located on at least one side of the touch area 10A. The touch area 10A is a relatively large area including the central area of ​​the touch screen panel 10 . The w...

specific Embodiment 2

[0038] See Figure 4 and Figure 5 , the embodiment of the present invention further provides a touch screen panel 20 , the touch screen panel 20 includes an insulating substrate 12 , an adhesive layer 13 , a transparent conductive layer 14 , a plurality of sensing electrodes 16 , and a plurality of wires 18 . The plurality of sensing electrodes 16 are arranged at intervals on opposite sides of the transparent conductive layer 14 , and each sensing electrode 16 is electrically connected to the transparent conductive layer 14 .

[0039] The difference between the first embodiment and the second embodiment is: the sensing electrode 16 is only arranged on one side of the transparent conductive layer 14 in the first embodiment, while the sensing electrode 16 is arranged on the transparent conductive layer 14 in the second embodiment opposite sides. Regarding the rest of the structure and materials of the touch screen panel 20 , the second embodiment is the same as the first embo...

Abstract

The invention discloses a touch screen panel which comprises an insulation substrate, a transparent conducting layer, a plurality of sensor electrodes and a plurality of lead wires. The touch screen panel comprises a touch area and a route area. The transparent conducting layer is fixed on one surface of the touch area corresponding to the insulation substrate, the plurality of sensor electrodes are mutually arranged at intervals and are electrically connected with the transparent conducting layer, the plurality of lead wires are laid in the route area and are used for the electrical signal transmission between the sensor electrodes and an external controller, wherein the touch area comprises at least a first touch area, and the quantity distribution density per unit area corresponding to the sensor electrodes of the first touch area is greater than the quantity distribution density per unit area corresponding to the sensor electrodes of other touch areas.

Description

technical field [0001] The invention relates to a touch screen panel. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display device such as a liquid crystal is increasing. A user of such an electronic device performs operations by pressing the touch panel with a finger, a stylus, or the like while visually confirming display contents of a display device located behind the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. [0003] When using a touch screen panel for touch, especially for multi-touch, higher resolution is required by users. One of the methods to improve the resolution of the touch screen is to increase the number of sensing electrodes so that the sensing electrodes are ...
