Infrared touch screen
The infrared touch screen selects the infrared matrix densely packed in the X, Y direction to detect and locate the user's contact, the infrared touch screen is provided with the outer frame of the circuit board on the front side of the display, and the circuit board is provided with the infrared emitting tube and the infrared receiving tube on the four side sides of the screen, corresponding to the horizontal and straight crossing of the infrared matrix. The infrared touch screen has the advantages of high light transmittance, no current, voltage, static interference, high contact stability, etc., but the infrared touch screen is affected by the ambient light and the infrared light source. Remote control, high-temperature objects, incandescent lamps, etc. influence, while decreasing its accuracy.
Sound touch screen
Surface acoustic touch screen.
The surface acoustic touch screen is a sonologically localized contact skill with sensors posted in the four corners of the touchscreen to send and receive sound waves at X and Y, and to carve 45° reflective stripes around them. When the finger touches the screen, the finger absorbs part of the sound energy, and the controller detects the attenuation of the received signal at a certain time and calculates the position of the contact point.
The surface acoustic skill is very stable and has high accuracy. In addition to the X and Y coordinates that a normal touchscreen is able to respond to, it also responds to its common third axis, the Z-coordinate, the pressure axis response. With this function, each contact not only has a contact and non-contact double switching condition, but also an analog switch with inductive force: the higher the pressure, the greater the attenuation gap on the accepted signal waveform. Deeper and deeper.
Light is like a touch screen.
A light image touchscreen is a contact skill that uses light to locate light sources and capture sensors at the four corners of the screen. When an object touches the surface of the touchscreen, the light changes, and the contact integrated circuit module analyzes the light sensor. This change determines the location of the contact. The optical image touch screen has high durability, is suitable for complex environments, and supports multi-point contact, but it is easy to be misidentified by ambient light, dust, insects, etc. Now, the skill is only available for desktop monitors over 10 inches.
Electromagnetic induction touch screen.
The sensor of the electromagnetic touch screen sits behind the display, and the sensor creates an electromagnetic area on the surface of the display. Sensors on the exterior of the electronically inductive touchscreen pen contact display are able to determine the position of the contact point by calculating electromagnetic changes. Compared with other touch screen skills, electromagnetic induction touch screen has high precision, low resolution, low power consumption and light weight. Ideal for war environments and built environments. Now, the skill is primarily used in the United States military.
