7.8 Inch Black Silk Printing SIS IC Controller Projected Capacitive GG Touch Panel
1. Product Description
Master Touch 7.8 inch GG touch screen panel can be used in POS, coffee machine, smartphone, tablet, etc. There are two types of G+G structures: SITO and DITO. Master Touch G+G structure touch screen adopts DITO (Dual ITO) technology. From top to bottom is Cover glass, OCA, ITO1 and ITO2, and sensor glass.
Capacitive touch panel works through body's current induction.When finger is on or close to touch panel surface,due to body electric field, the user and touch panel surface forms one coupling capacitance.
Master Touch 7.8 inch touch screen panel can be used in POS, coffe machine, smartphone, tablet, etc.
