Description

Matrix touch panel

technical field

The utility model relates to a matrix touch panel, in particular to a matrix touch panel capable of reducing uneven chromaticity.

Background technique

At present, touch screens on the market can be mainly divided into two types according to the physical principle of detecting touch points. One is resistive touch technology, which uses fingers or other contacts to lightly press the screen to generate voltage. It is a capacitive touch technology, which uses the weak current generated by the human body to change the electric field to achieve the effect of induction.

Among them, whether it is resistive or capacitive touch technology, it is divided into analog touch technology and digital touch technology. The manufacturing process of analog touch technology is relatively simple, so it has been widely used in various industries, but this This kind of analog touch technology cannot realize the function of multi-touch. In addition, this kind of analog touch technology needs to do positioning correction regularly, which reduces the convenience in use, and is also prone to electromagnetic wave interference due to external noise. It is also a problem with this technique that causes positioning errors.

The later developed matrix touch technology uses the principle of digital transmission to realize the function of multi-touch, and can accurately locate without calibration. The existing known production method is to coat a conductive film such as ITO film or ATO film on the substrate such as glass or plastic, and then form the desired pattern on the substrate by etching. If it is used in For resistive touch panels, there is an air layer in the middle of the conductive film. If it is used for capacitive touch panels, there is an insulating layer in the middle of the conductive film. Higher manufacturing costs. Therefore, another method developed by the industry is to form the pattern of conductive film by printing, which can reduce the cost, but the gap between the units of the pattern formed by printing is relatively wide, so a problem has arisen: the general conductive The film itself is not completely colorless and transparent. If a conductive film with high transparency is required, the cost is extremely high, and the application to the industry is limited. However, when the gap between the cells is small, the general conductive film is difficult for people to use. The visual acuity is still unable to detect the chromaticity difference between the conductive film and the substrate, but when the gap is wide, it is easy to see the lines caused by the chromaticity difference between the two materials. The uneven chromaticity of the touch technology still needs to be improved.

This is obviously the relevant industry. urgent problem to be solved. Therefore, how to create a matrix touch panel with a new structure is one of the current important research and development topics, and it has also become a goal that the industry needs to improve.

The matrix touch panel with structure can improve the common existing touch technology and make it more practical. Through continuous research, design, and after repeated trial samples and improvements, the utility model with practical value is finally created.
