What is touch screen digitizer and LCD screen display?
To help you make sense of What is touch screen digitizer and LCD screen display, to know more exactly what repair replacement you need.
A touchscreen display is one that is sensitive to touch. They are often used on GPS, PDA, smartphones and similar devices. The primary types of touchscreens are capacitive touchscreens and resistive touchscreens, but there are alo other types infrared light grids, sound, or optical sensors. Touchscreen is also said as digitizer.
There are two major categories of touchscreen displays used on cellphones and GPS: capacitive touchscreens and resistive touchscreens. Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, resistive type touchscreens require much more pressure to activate than capacitive touchscreens.
Currently most of the GPS still using the resistive touchscreens. Such as: Tomtom XL series and Garmin nuvi 14xx series. But nearly all cellphones use the capacitive touchscreens now. Most resistive touchscreens needs soldering.
Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand. Some new GPS start to use the Capacitive touchscreen now.
