The three corners of the sound wave screen are respectively pasted with transducers for transmitting and receiving sound waves in the X
and Y directions (transducer: made of special ceramic materials, divided into transmitting transducers and receiving transducers. It controls The electrical
signal sent by the device through the touch screen cable is converted into sound wave energy and the surface acoustic wave energy formed by the reflection
stripes is converted into an electrical signal.), the four sides are engraved with reflection stripes that reflect surface ultrasonic waves. When a finger or soft object touches
the screen, part of the sound wave energy is absorbed, thus changing the received signal. After processing by the controller, the X and Y coordinates of the touch are obtained.
6 categories let you understand the development trend analysis of touch screen
After Apple launched a series of smart terminals, the touch screen industry has developed rapidly in recent years, and related products have become hot sellers in the market.
In the future, the application fields of touch display screens will become more widespread in daily life.
Analysis of touch screen types and various technology development trends
1. Types of touch screen technology
The touch screen is a positioning device that allows users to directly input coordinate information to the computer with their fingers
. Like the mouse and keyboard, it is also an input device.
Touch screens have many advantages such as durability, fast response, space saving, and ease of communication. Using this technology, you can operate the host by gently touching the
icons or text on the computer display with your fingers, making human-computer interaction more direct. This technology
greatly facilitates those who do not know how to operate computers. User. It has been widely used in control, information query and other
aspects in the fields of industry, medical treatment and communication.
1. Resistive touch screen
Analog resistive screen
Analog resistive touch screen is what we usually call “resistive screen”, which is a touch screen controlled by pressure sensing. It uses two layers of ITO (indium tin oxide) plastic films plated with
conductive functions. The two pieces of ITO are equipped with particle fulcrums, so that when the screen is not pressed, there is a certain gap between the two layers of ITO and is in a non-conductive state.
When the operator presses the screen with his fingertip or pen tip, the pressure will cause the film to be concave, causing the ITO layer to contact the conductor due to deformation. The corresponding pressure
point is then calculated by detecting the voltage changes in the X-axis and Y-axis to complete the entire screen. touch processing mechanism. Currently, there are many types of analog resistive touch screens,
such as 4-wire, 5-wire, 6-wire, and 8-wire. As shown in Figure 1, the more wires, the higher the detection precision, but the cost will also increase. The resistive screen does not support multi-touch, has high power
consumption, and short lifespan. At the same time, long-term use will cause detection point drift and requires calibration. However, resistive screens have simple structures and low costs. Before capacitive
touch screens matured, they once occupied most of the touch screen market.
digital resistive screen
The basic principle of the digital resistive screen is similar to the analog one. Unlike the analog resistive screen, which evenly coats the
ITO layer on the glass substrate, the digital resistive screen just uses a
substrate with ITO stripes. The ITO stripes on the upper and lower substrates are perpendicular to each other. The digital resistive screen is
more similar to a simple switch, so it is usually used as
a membrane switch. Digital resistive screens enable multi-touch control.
2. Capacitive touch screen
surface capacitive
Surface capacitive touch screens sense touch behavior on the screen surface through electric field induction. Its panel is a uniformly coated ITO
layer. Each of the four corners of the panel has an outlet wire
connected to the controller. During operation, the surface of the touch screen generates a uniform electric field.
When a grounded object touches the screen surface, the electrodes can sense the change in charge on the screen surface and determine the
coordinates of the touch point. Surface capacitive touch screens
have long service life and high light transmittance, but have low resolution and do not support multi-touch. They are currently mainly used in large-size
outdoor touch screens, such as public information platforms
(POI) and public service (sales) platforms (POS). ) and other products.
Projected capacitive screen
Projected capacitive touch screens use electrostatic field lines emitted by touch screen electrodes for sensing. Projected capacitive sensing technology
can be divided into two types: self-capacitance and interactive
capacitance. Self-capacitance is also called absolute capacitance. It uses the sensed object as the other plate of the capacitance. The object induces
charge between the sensing electrode and the sensed electrode
, and the position is determined by detecting changes in the coupling capacitance. But if it is a single touch, through capacitance changes, there is
only one set of coordinates determined in the X-axis and Y-axis directions,
and the combined coordinates are also unique; if there are two points of touch on the touch screen and the two points are not in the same X direction
Or in the same Y direction, if there are two coordinate
projections in the X and Y directions, 4 coordinates are combined. Obviously, only two coordinates are real, and the other two are commonly known as
“ghost points”. Therefore, self-capacitive screens cannot achieve true multi-touch;
interactive capacitance is also called crossing capacitance, which is the capacitance generated through the coupling of adjacent electrodes. When the
sensed object is close to the electric field line from one electrode to
another electrode, the interaction The change in capacitance will be felt. When the horizontal electrodes send out excitation signals in sequence, all
the vertical electrodes will receive the signal at the same time. In this way, the
capacitance value of the intersection of all horizontal and vertical electrodes can be obtained, that is, the two-dimensional plane of the entire touch
screen. Capacitor size. When human fingers approach, the local capacitance will
decrease. Based on the two-dimensional capacitance change data of the touch screen, the coordinates of each touch point can be calculated.
Therefore, even if there are multiple touch points on the screen, each touch point can be calculated. the real coordinates.
In both types of projected capacitive sensors, the sensing capacitance can be designed in such a way that the touch of a finger is detected at any
given time. The touch is not limited to one finger, but can also be Multiple fingers. Since 2007,
with the great success of Apple”s iPhone and iPad series products, projected capacitive screens have begun to develop rapidly, quickly replacing
resistive touch screens and becoming the mainstream touch technology in the current market.
