LCD Touch Screen Principles and Basic Knowledge Full Analysis

LCD Touch Screen has been visible around us. In the field of PDA and other personal portable devices, the touch screen saves space for easy carrying, as well as better human -computer interaction.

LCD Touch Screen can adjust the performance of this substance by adjusting the proportion of 铟 and tin, deposition method, degree of oxidation, and grains. The thin ITO material is good, but the impedance is high; the thick ITO material is low, but the transparency will deteriorate. When depositing on the PET polycipotic film, the reaction temperature must be dropped below 150 degrees, which will cause ITO to be incomplete. In the subsequent application, ITO will be exposed to the air or air compartments. Change of time. This makes the resistance touch screen needs to be corrected frequently.
