High Quality 55" Capacitive Touch Sensor 4K Interactive Touch Flat Panel Multi Touch Smart White board

when pressure is applied using a finger, stylus, or another device on a resistive screen, the signal is transferred from one adjacent layer to the next until it is finally interpreted as a touch event. Because touch is based on pressure generated on the screen, most items ranging from a fingernail to a wooden rod can be used on resistive screens.

On the downside, resistive touchscreens normally have poor contrast because of multiple layers, with images that are less sharp compared with capacitive touchscreens. The touch effect is also comparatively slow because of the mechanism of signal transfer. Still, many low-end smartphones, some game consoles such as Nintendo DS, and most POS terminals and ATM machines have utilized the technology for their displays.
