智能板2075 pro显示。20世纪90年代后半期，第二代便携式信息终端增加了通信等功能。即使到了第三代，它们仍被用作辅助工具，帮助用户记忆、浏览信息或在日常生活中执行服务。与此相对应的是液晶显示器的年复一年的进步，因此对触摸屏光学特性或耐用性的要求也会逐年提高。电阻式触摸屏的关键是材料技术。常用的透明导电涂料材料有:A、ITO涂层、氧化铟、弱导体，特点是当厚度减少到1800埃(Angstrom = 10-10米)时，它会突然变得透明，透光率为80%，再薄一点透光率就会下降，当厚度达到300埃时，可达到80%。ITO是所有电阻式触摸屏和电容式触摸屏使用的主要材料。这两种技术的触摸屏工作表面都是ITO涂层。？? B. Nickel-gold coating, the outer conductive layer of the five-wire resistive touch screen uses a highly ductile nickel-gold coating material. Because the outer conductive layer is frequently touched, the use of a ductile nickel-gold material is intended to extend Service life, but the process cost is relatively high. According to the different coatings and the number of wires, the resistive touch screen is divided into four-wire resistive screen and five-wire resistive screen. Their common points are: ?? A, high resolution, high-speed transmission response; ?? B, one-time calibration, high stability; ?? C, high surface hardness, reduce scratches, scratches and chemical treatment; ?? D. Two kinds of surface treatments can be performed (that is, glossy and matte). The differences are as follows: ?? The two transparent metal layers of the four-wire resistive touch screen each increase 5V constant voltage when working: one vertical direction and one horizontal direction. A total of four leads are required for the entire touch screen. Its service life is no less than 1 million times for a single touch, and no less than 100,000 times for a line.
