Capacitive touch device structure

Abstract

The invention discloses a capacitive touch device structure, which comprises a first transparent substrate and a second transparent substrate, wherein an image layer is arranged at the periphery of a lower surface of the first transparent substrate; a first transparent conductive film, a second transparent conductive film and a plurality of first circuits and second circuits are correspondingly arranged on opposite surfaces of the two transparent substrates; and the first transparent substrate and the second transparent substrate are adhered through an adhesive layer. Therefore, after two opposite surfaces of the capacitive touch device are jointed, the same plane can be formed between the first / second transparent conductive film and the first / second circuits, and the thickness of the capacitive touch device can be effectively reduced. Meanwhile, the light transmittance is improved; and during production, a hierarchical structure between the first / second transparent conductive film and the first / second circuits can be simplified, an adhering process is reduced to improve the yield, and the production process is simplified.

Description

technical field [0001] A touch device, especially a capacitive touch device structure that can reduce the thickness of the touch panel, increase the light transmittance, and simplify the manufacturing process. Background technique [0002] The common types of touch panels are resistive, capacitive, ultrasonic, optical (infrared) and so on. Among them, the most widely used is resistive, followed by capacitive. However, the advantages of capacitive touch panels are waterproof, Scratch resistance, high light transmittance, and wide applicable temperature range, etc. Although the price of capacitive touch panels is relatively high, as the technology matures, it has gradually entered the market for small-sized touch panels. [0003] see figure 1 As shown, it is a schematic structural diagram of a known touch panel structure. As shown in the figure, a commonly used touch panel 1 has at least two PET substrates 12, and conductive layers 13 are respectively provided on the correspo...

[0004] Another example is the Taiwan Patent Gazette of China, the capacitive touch panel with the notification number M355426, which includes a hard substrate and a patterned conductive film, the upper surface of the hard substrate is the touch terminal of the touch panel, and the lower surface is formed with At least one shielding pattern, a visible area and a plurality of guiding lines, the visible area is surrounded by the at least one shielding pattern, these guiding lines are formed on the shielding pattern and extend together to the peripheral side of the shielding pattern; the patterning The conductive film includes a plurality of electrode lines, which correspond to the visible area and are respectively connected to the guide lines. In this invention, the lower surface of the hard substrate is provided for the structural wiring of the touch panel, and the patterned conductive layer As described in the previous patent, the induction electrodes of the vertical axis and the horizontal axis are also made on one side of the substrate, and an insulating layer is arranged on the induction electrodes, so that at least one end of the insulation layer is hollowed out relative to each induction electrode. Finally, a layer of transparent conductive film is coated on the insulating layer to form a bridge wire after a patterning process. Although this structure reduces the use of substrates, it requires multiple coatings on a single substrate in the process. , etching process
