Gtouch GP-121F-5H-N15B Touch Screen Monitor Repair

Order each part separately is available

GP-121F-5H-N15B touch panel is composed of a layer of conductive film (ITO Film) and a layer of conductive glass (ITO Glass). The GP-121F-5H-N15B Touch Digitizer Spacer Dots is also used for insulation between the film and glass. The five-wire resistive GP-121F-5H-N15B HMI Panel Glass is designed according to this structure, since its main X-axis or Y-axis line is not on the outermost film but on the glass, so the durability and reliability are different to the 4-wire resistive product. The difference between 5-wire and 4-wire is that for 5-wire both the X-axis and Y-axis are made on the glass surface, and the upper ITO Film is only used for grounding. The X-axis and Y-axis are respectively routed from the four corners of the action area, and the positive voltage forms a loop with the grounding wire. The voltage value also forms a uniform electric field, and the coordinate position is detected by calculation.
