High temperature sintering 5-wire resistor touch panel

The high-reliability five-wire resistive touch screen made by high-temperature sintering process has high stability because the coordinate detection is on ITO glass, which can be used in high-end industrial and military equipment; The square resistance is more uniform, the electrode resistance is more stable, and it has higher linearity and reliability, and can work for a long time in a wide temperature range without drift; The five-wire resistive touch screen made by high-temperature sintering is suitable for higher-end fields; If you have high-end requirements, please contact: www.jiechengtech.com. At present, the only manufacturer of high-temperature sintered five-wire resistive touch screen in China is jiechengtech;

Principle of five-wire touch screen: Signal acquisition method of five-wire resistive touch screen, Four driving modules are set to set the high and low levels of four input signals on the five-wire resistive touch screen to realize the acquisition conditions of X coordinates and Y coordinates. A RC series circuit is arranged between the output end of the FPC lead of the five-wire resistive touch screen and the AD pin of the CPU. After the acquisition conditions of X coordinate and Y coordinate are set, the output voltage signal of FPC lead on the five-wire resistive touch screen is respectively transmitted to the AD pin of CPU through RC series circuit, and AD conversion is completed in the CPU to realize data acquisition, and then the final collected data is confirmed by the absolute value of average value and difference value; The invention has the advantages that the proprietary AD chip is replaced by four driving modules, an RC series circuit and an AD conversion function module provided by the CPU to realize the acquisition of the touch signal of the five-wire resistive touch screen, which is easy to obtain and suitable for use in the industrial military control field.

Five-wire resistive touch screen is the most accurate and reliable top-level resistive touch screen in the world, and its technology has been monopolized by American and Japanese manufacturers for a long time. In 2016, jiehcngtech broke through the technical difficulties, and mass-produced high-temperature sintered five-wire resistor products in 2016. Since the products came out, they have been well received by users, and the supply is in short supply. High-temperature sintered five-wire resistive touch screen completely shields the influence of external environment, even if the surface is damaged, it still runs freely, and the product life is 10 times that of four-wire resistive screen.
