Question

Each of these is a basic type of a touch screen, except ________. Select one:

a. Surface acoustic wave
b. Reflective
c. Resistive
d. Capacitive

Answer 1

Option B, Reflective

Step-by-step explanation:

There is no reflective touch screen terminology used in present time.

However, A touch screen can be of several types such as

a) Infrared

b) Resistive

c) Capacitive- Where insulator at one side is coated with transparent conducting material and electrodes are placed at all the corners of the screen

d) Surface acoustic wave in which sound waves travel in parallel direction across an elastic surface.

e) shadow sense etc.

Answer 2

Each of these is a basic type of a touch screen, except b. Reflective.

Surface Acoustic Touch screen is atype of touch screen that uses ultrasonic waves to detect touch events.

Resistive touch screens consist of two layers of transparent material and an air gap between. When the user applies pressure to the outer layer, it touches the inner layer at specific locations. This type of touchscreen is less sensitive.

Capacitive touch screens consist of a glass overlay, which is coated with a conductive material. Contact with a capacitive screen creates an electrostatic charge, which then sends information to the touch control.
