Resistive Touchscreens
Resistive is the most common type of touchscreen technology. It is a low-cost solution found in many touchscreen applications, including hand-held computers, PDAs, consumer electronics, and point-of-sale-applications. It is ideal for screen sizes up to 12.1”.
A resistive touch screen uses a controller and a specially coated glass overlay on the display face to produce the touch connection.
The primary types of resistive overlays are 4-wire, 5-wire, and 8-wire. The 5-wire and 8-wire technologies are more expensive to manufacture and, although they claim superior ruggedness, they use the same fragile PET film on the front which is susceptible to damage. Resistive touch screens substantially reduce light throughput and thus provide lower image clarity.
Two options are generally given: polished or anti-glare.
Polished offers clarity of image, but generally introduces glare.
Anti-glare will minimize glare, but will also further diffuse the light,
thereby further reducing the clarity.
One benefit of using a resistive display is that it can be accessed with a finger (gloved or not), pen, stylus, or a hard object.
The resistive screen is the most popular technology because of its relatively low price (at smaller screen sizes), and ability to use a range of input means (fingers, gloves, hard and soft stylus).
