is macbook air 13 inch touch screen.Attempts to use the surface capacitive touch technology on the back of the panel always encounter the " hand shadow effect " . This phenomenon will cause a large induction error to the touch screen, because the user's hands and wrists near the panel will cause capacitive coupling problems. , And because the approaching angle and distance are quite random, the coupling capacitance value is uncertain.
