Embodiment 1
[0037] The concrete manufacturing process of a kind of touch screen conductive bridging of the present invention is as follows:
[0038] Step 1: Select a glass substrate coated with a conductive material (this conductive film can be ITO, FTO, AZO or BZO), that is, the touch screen electrode 1, for cleaning and decontamination;
[0039] Step 2: Pattern the touch screen electrodes 1 according to a preset pattern (rhombic pattern in this embodiment). That is, the touch screen electrodes are etched into a plurality of X electrodes 2 along the X-axis direction and a plurality of Y electrodes 3 along the Y-axis direction, wherein the X electrodes 2 remain continuous in the X-axis direction, and when the X electrodes 2 and the Y electrodes 3 intersect area, the Y electrode 3 is etched to be disconnected.
[0040] Step 3: An insulating layer is prepared on the X electrode 2 layer in the intersection region mentioned in step 2, so as to ensure that the X electrode 2 is insulated from ...

Abstract
The invention relates to a touch screen technology, and discloses a touch screen electric conduction bridging. A touch screen comprises a glass substrate, and a layer of electric conduction materials is deposited on the glass substrate, namely a touch screw electrode is formed. The touch screen electrode is etched to form a plurality of X electrodes along the X axis direction and a plurality of Y electrodes along the Y axis direction, the X electrodes keep continuous in the X axis direction, the Y electrodes are etched to be broken in a cross area of the X electrodes and the Y electrodes, an insulating layer is prepared on an X electrode layer in the cross area so as to ensure insulation between the X electrodes and the Y electrodes, a layer of transparent non-metal electric conduction polymer film is printed on the insulating layer so as to enable the Y electrodes to be conductive, namely an electric conduction bridging is formed. According to the touch screen electric conduction bridging, a transparent non-metal electric conduction polymer solution is used, a screen printing technology is adopted to prepare the electric conduction bridging, and compared with a transitional MoAlMo metal bridging technology prepared by adopting magnetron sputtering equipment and a yellow light manufacture procedure, the touch screen electric conduction bridging greatly reduces production cost, greatly simplifies a production technology and a manufacture procedure, and greatly improves flexibility of production arrangement.
Description
technical field [0001] The invention relates to touch screen technology, in particular to a touch screen conductive bridge. Background technique [0002] As a new human-computer interaction device, the touch screen is widely used in various digital information systems because of its simple and convenient input methods. From small products such as mobile phones, cameras, game consoles to handheld computers, car display screens, GPS (Global Satellite Navigation System), POS (Point of Sale Terminal), public information inquiry systems, medical devices, and touch-type PDPs commonly used in TV news programs Touch screen products can be seen on the Internet, and the market prospect is extremely broad. [0003] In the production of multi-point capacitive touch screen, the sensing layer of the traditional double-sided multi-touch sensor is composed of the upper line pattern sensing layer and the lower line pattern sensing layer, but the upper and lower sensing layer patterns are pa...
