Description

Technical Field

[0001] The utility model relates to touch screen technology, in particular to a silver paste binding position structure and a touch screen. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an input device commonly used in mobile devices, computers, kiosks, ATMs, etc. It allows users to interact with the device by touching the screen instead of a traditional mouse or keyboard.

[0003] A binding position is provided on one side edge of the existing touch screen, and the touch screen can be bound to a flexible circuit board or a flat cable through the binding position, and then electrically connected to a controller through the flexible circuit board or the flat cable to output touch signals and receive control signals.

[0004] Screen silver paste is a manufacturing process for the binding position on the touch screen, which forms the binding pins of the binding position on the touch screen by screen printing. However, after long-term use, the conductive silver paste will have silver ion migration problems, which may cause the ground pin and signal pin of the touch screen to be connected by silver ions, resulting in a short circuit problem, affecting the use of the product. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a silver paste binding position structure, which can improve the reliability and service life of the touch screen.

[0006] The utility model provides a touch screen, comprising the above-mentioned silver paste binding position structure.

[0007] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0008] A silver paste binding bit structure includes at least one sub-binding area, each sub-binding area is provided with at least one grounding silver paste pin and at least two signal silver paste pins, each grounding silver paste pin has a first distance from an adjacent signal silver paste pin, each signal silver paste pin has a second distance from another adjacent signal silver paste pin, and the first distance is greater than the second distance.

[0009] Furthermore, the first distance is 0.75 mm-1.10 mm.

[0010] Furthermore, the second distance is 0.22 mm-0.33 mm.

[0011] Furthermore, the number of grounding silver paste pins in each sub-binding area is two, and the two grounding silver paste pins are respectively arranged on both sides of each signal silver paste pin along the arrangement direction.

[0012] Furthermore, there are multiple sub-binding areas, which are arranged in sequence. The closer to the middle sub-binding area, the larger the distance between each grounding silver paste pin and the adjacent signal silver paste pin, and the closer to the sub-binding area on both sides, the smaller the distance between each grounding silver paste pin and the adjacent signal silver paste pin.

[0013] Furthermore, the sub-binding area includes a binding transmission area and a binding receiving area, the signal silver paste pins include signal transmission pins and signal receiving pins, the signal silver paste pins in the binding transmission area are all signal transmission pins, and the signal silver paste pins in the binding receiving area are signal receiving pins.

[0014] Furthermore, the ratio of the number of the bound transmitting areas to the number of the bound receiving areas is 1:2.

[0015] A touch screen comprises a transparent substrate, a touch sensor, a touch wiring and the above-mentioned silver paste binding structure arranged on the transparent substrate, wherein the touch sensor is electrically connected to the silver paste binding structure through the touch wiring.

[0016] Furthermore, the transparent substrate includes a touch area and a peripheral area, the peripheral area surrounds the touch area, the touch sensor is located on the touch area of ​​the transparent substrate, the touch traces and the silver paste binding structure are located on the peripheral area of ​​the transparent substrate, wherein the silver paste binding structure is located on one side edge of the peripheral area.

[0017] Furthermore, the touch screen also includes peripheral ink, and the peripheral ink is arranged between the peripheral area of ​​the transparent substrate and the touch wiring and the silver paste binding structure.

[0018] The utility model has the following beneficial effects: the silver paste binding position structure of the utility model increases the distance between the grounding silver paste pin and the signal silver paste pin so that the distance between each grounding silver paste pin and the adjacent signal silver paste pin is greater than the distance between each signal silver paste pin and another adjacent signal silver paste pin. When the grounding silver paste pin and the signal silver paste pin have the problem of silver ion migration after long-term use, since the distance between each grounding silver paste pin and the adjacent signal silver paste pin is larger, each grounding silver paste pin will not be connected to the adjacent signal silver paste pin by silver ions, thereby improving the reliability and service life of the touch screen.
