New Description: [New Technology Field] This creation is about a matrix touch panel, especially a matrix touch panel that reduces chromaticity unevenness. * [Prior Art] - At present, the touch screen on the market can be based on the physical principle of detecting touch points. It is mainly divided into two types, one is resistive touch technology, and the screen is tapped with a finger or other contact head. In order to generate a voltage, a capacitive touch technology is used to induce an electric field by a weak current generated by a human body during a touch. Among them, the resistive or capacitive touch technology is divided into analog touch technology and digital touch technology. The analog touch technology has a simple process, so it has been widely used in various industries, but this The analog touch technology cannot realize the multi-touch function. In addition, the analog touch technology needs to perform positioning correction regularly, which reduces the convenience in use, and is also easy because of external noise. Electromagnetic interference causes positioning errors is also a problem with this technology. Later developed matrix touch technology utilizes the principle of digital transmission to realize the multi-touch function, and can accurately locate without correction. The conventional method is to form a conductive film such as an ITO film or a ruthenium film on a substrate such as glass or plastic, and then form an image on the substrate by etching, if used in a resistive touch. The control panel has an air layer in the middle of the conductive film. If it is used on the capacitive touch surface -3- M369503 board, there is an insulating layer in the middle of the conductive film. This method needs to be matched with the mask and the exposure and development process, the process is cumbersome and needs Higher manufacturing costs. Therefore, the industry has developed another method of forming a pattern of a conductive film by printing, which can reduce the cost, but the gap between the units of the pattern formed by printing is wider, thus causing a problem: a general conductive film It is not completely colorless and transparent. If the conductive film with high transparency is required, the cost is extremely high, and the utilization of the industry is limited. However, the general conductive film is applied to the gap between the cells is small, and the human vision is 尙The difference in chromaticity between the conductive film and the substrate is not noticeable, but when the gap is wide, it is easy to see the texture caused by the difference in chromaticity between the two materials. Therefore, capacitive touch is currently produced by printing. The phenomenon of uneven chromaticity of technology still needs to be improved.
