touch screen lcd newegg.The initial transparent conductive film had a low light transmittance, and its color was basically yellow or brown. In addition, as a transparent switch, the resistance value of the transparent electrode portion tends to increase under high temperature and high humidity. Therefore, digital products can only be used for menu input like the button mode. Into the 1990s, as the first generation of Pocket PC portable information terminal equipped with a high-end analog touch screen. Its basic structure is the same as digital products, except that the main materials, ITO conductive film and ITO conductive glass, have higher resistance. The following is the circuit working principle of the analog touch screen. The "conductive film" in the following figure is the conductive coating.
