touch screen lcd j5.The inner surface of the panel capacitor cost quite resistive touch screen , it is a single layer or double layer ITO structures, having a higher light transmittance, the assembly is more simple and inexpensive, even in the harshest environments has stable performance, and In theory, its service life is infinite (no need to press) , and the mechanical structure of the internal surface capacitive touch screen is greatly simplified. The general choice is an anisotropic pattern, which is actually a set of horizontal conductor bars separated by an equal gap. The touch screen is fully protected by the front panel, so that it cannot be damaged, and because there is no mechanical movement and no wear mechanism , the life of the touch screen is greatly extended . Because there is no air between the two films , the light transmittance of such touch screens is generally close to 90%.
