The Different Types of Touch Screens
There are different types of touch screens. These include resistive, 5-wire, and
surface capacitive touch screens film กระจก. You can learn more about them in this article. This
article also includes information on infrared and surface wave touch screens. Each
type is used for different applications and has their own pros and cons.

Resistive to 5-Wire Touch
There are several benefits to 5-wire resistive touch technology over capacitive touch
technology. Resistive touch devices can recognize touches by sensing the pressure.
This means that they can work with gloves or bare fingers ติดฟิล์มกระจกบ้าน. They are also much more
durable and can be used in harsh environments.
Resistive touchscreens have two layers, with each layer having electrodes that
measure the voltage produced by the opposite layer. This allows the device to
determine the exact point of contact when the surface is touched. This technology is
less common than capacitive touch.
Surface capacitive touch screen
Surface capacitive touch screens use an ITO on the touch screen surface to detect
human body contact. This conductive layer changes electrical current, and a sensor
at the edges registers this change and sends it to a controller as an analog signal.
The controller processes the signal, and then sends it to a system, where the
information is displayed on a monitor.
Surface capacitive touch screen sensors are made of single or multiple layers of
material. Each layer contains an electrical conductor, and the assembly is sealed
from the rest of the environment. When a person touches the screen, electrical
conductors in the film complete the circuit. The resulting change in signal is
recorded as a touch event. Surface capacitive touch screens have many advantages
over resistive touch technology, which requires physical pressure to detect touch.

Infrared touch screen
Infrared touch screen technology is a type of touch screen that uses infrared light to
recognize touch input. This technology is used in a variety of devices, from kiosks
and ATMs to medical instrumentation and commercial transportation. Its advantages
include simplicity, low cost, and feasibility. Unlike other types of touch screens, IR
touch screens do not require any special equipment to work. Users can operate an
IR touch screen with anything, from a finger to a metal stylus.
Infrared touch screen technology works by using an array of IR LEDs around the
perimeter of the screen. When a user touches the screen, the LEDs are disrupted
and the photodetector notices the change. Because of this, the IR touch screen is
able to simulate a mouse click in the touched area. This allows users to open files
and click buttons without the use of a mouse.
Surface wave touch screen

The surface wave touch screen is a type of touchscreen that recognizes touch
positions along a predetermined axis. It can be used in a cathode ray tube display
panel, or in other touch-controlled devices. These screens can also be used in an
environment other than the computer’s display, such as in an automobile.
To create a surface wave touch screen, two transducers (T1, T2) launch surface
acoustic waves in opposite directions. Two absorbers (SWA) mounted behind the
transducers absorb the wave energy.
