Touch-panel electrode bridging structure

Abstract

The invention discloses a touch-panel electrode bridging structure, and particularly relates to a touch-panel electrode bridging structure capable of increasing a conduction rate of upper-and-lower-layer electrodes. A touch panel contains a conductive glass substrate and a conductive film disposed on the conductive glass substrate. A ring-shaped electrode circuit is printed around an upper surfaceof the conductive glass substrate to control four wires of an X axis and a Y axis. The structure is characterized in that at least two conductive bridging parts are disposed on at least two opposingsides of the electrode circuit, and all the conductive bridging parts can simultaneously be in conduction with the conductive glass substrate and the conductive film, and are in parallel connection with signal wires. Therefore, the upper and lower electrodes of the touch panel of the invention can utilize the multiple conductive bridging parts in connection with the signal wires to sense conduction, the conduction rate of upper and lower layers is effectively increased, workloads of the touch panel are reduced, and thus the purpose of energy saving is achieved; and compared with the prior art,the structure can reduce a structure hierarchy thereof, and can thus reduce working procedure, shorten working time, and then reduce manufacturing costs of the touch panel.

Problems solved by technology

[0004] It can be seen from the above description that the signal line needs to be very accurate when receiving and transmitting the measured voltage value, otherwise it will directly affect the accuracy of its coordinate calculation. However, the existing five-wire resistive touch panel is as follows: Use the silver wire 25 on the lower surface of the conductive film 20 to transmit, and then gather the silver wire 25 at the corresponding soft board signal contact, and lead it out through a conductive bridging body. Due to the long distance of the silver wire 25, there will be attenuation during transmission. The problem is that its conduction rate cannot be improved, which affects its sensitivity and accuracy

[0005] In other words, due to the poor conductivity of the upper and lower conductive layers 11 and 21 of the existing five-wire resistive touch panel, it is necessary to increase the operating force of the touch panel to overcome this defect. However, this Not only is there a phenomenon of power consumption, but also it is easy to cause the touch panel to heat up rapidly during operation, causing damage to parts, thereby shortening its service life. Therefore, how to improve the conduction rate of the upper and lower layers and reduce the operating force of the touch panel is an important aspect of the present invention. Important issues to be improved

[0006] In view of this, the inventor of this case has engaged in research and development and manufacturing experience in related industries for many years, deeply discussed the needs of the aforementioned existing resistive touch panels, and actively sought solutions. After continuous efforts in research and trial production, he finally succeeded. Developed a touch panel electrode bridging structure to overcome the existing inconvenience and trouble caused by the insufficient conduction rate of the upper and lower layers
