china lcd panel ir 10 touch factory

We have full range of lcd advertising kiosk from 21.5inch to 86inch, IR touch screen stand can be inbuilt with face recognition camera, which can be in 50 degree or 90 degree, also internet camera can also be inbuilt.

OVERVIEW The ViewSonic® TD2423 is a 24” IR touch display designed for intuitive multi-touch use. Infrared (IR) touchscreen can detect up to 10 points of contact compared to optical touchscreens and can be operated by a stylus, fingers and gloved hands. The multi-touch input is more accurate, and the display is faster. Coupled with an adjustable tilt, you can easily interact with the TD2423 at an ideal position. This monitor features Full HD resolution to give you clear images and is built with scratch-resistant 7H hardness screen to surface damage. To support your work, the TD2423 is equipped with VGA, HDMI, DVI and USB connectivity.

You do not need to calibrate the image projector before lecturing; with LED lighting technology, IFPDs provide a clear image all the way; and thanks to the IR touchscreen, you can annotate your presentation with almost anything, a dry/wet finger, pen, or stylus.

Commonly, the overlay is a piece of protective glass hemmed in by the IR touch frame, in which Infrared LEDs and photodetectors are embedded. A kind of optical bezel will be inserted between the glass and the frame to fix the frame and transmit infrared light emitted by those LEDs.

Through the optical bezel, IR LEDs emit invisible infrared beams forming grids on the surface of the overlay, Photodetectors are installed across from the LEDs to detect interruptions of beams if touch events on the overlay happen.

There are two rows of IR LEDs, which generate horizontal and vertical invisible IR beams. They form a large beam grid that covers the surface of the overlay. In the meantime, two rows of photoreceptors are installed on the opposite side of the LEDs.

As long as an opaque object touches the surface, it will blot out the light beams. Photoreceptors in both directions (vertical and horizontal) can detect this interruption by that object, finally localize the x and y coordinates, and then send the signal to the processor to respond with relevant action.

Better display – without other substance between the LCD and overlay, IR touch screens offer the best light transmission, so they can render more vivid images without color and brightness loss.

Supports multi-touch – with windows and android 9.0 double OS, it can support as many as 40 touchpoints simultaneously. That means it can support up to 4 students interacting together on an IFPD.

Short response time – commonly less than 8ms, IR touch screens localized touch events by detecting light interruption, so they are accurate and quick to respond with actions.

More flexible in customizing screen sizes – by adjusting the numbers of LEDs and photodetectors embedded in the overlay frame, you can fit any custom-made monitor with an infrared touch interface

Clear images – compared with many camera or projector-based systems, equipment with IR touch screens often adopts backlight LED. So, wherever lighting environment they perform in, they can provide clear images to the audience.

Write with any object – you can write on an IR touch screen with anything, a bare finger, a gloved finger, wet hands, or a pen, as long as it is not transparent.

No calibration – a traditional smart projector board may require regular calibration to display correct pictures, however, devices with IR touchscreen do not need to calibrate the IR LEDs and sensors to guarantee a normal function.

No pressure is required to write – Resistive touch screen technology perceives the writing track by pressure, which can damage the screen after a long time of usage, while IR touch screen technology by detecting light interruption, so you can write freely without having to push hard on the screen.

Of touch screen technologies, infrared and projected capacitive are the top two types that are mostly utilized. However, they are applied to different applications due to the differences between them.

For PCAP touch screens, There is a layer of transparent electrode film that is fixed between the LCD panel and the cover glass, when the human finger touches the screen, the current through that film changes, and the signal of x and y position will be transferred to the computer.

For IR touch screens, the equipment detects the finger’s position by detecting the block of invisible lights from the infrared LEDs that are embedded in the touchscreen frames.

So you will often see a bezel in the IR touchscreen, which is used to transfer the infrared light to the surface of the overlay, while the PCAP touchscreen does not require the bezels.

IR touchscreen can be activated by anything that is not transparent, whereas PCAP types only accept bare fingers, thin surgical gloves, or cotton gloves.

The electrode film in PCAP touchscreens is expensive, especially when it comes to large screens, but for IR ones, when it is applied to large-scale screens, you only need to add a few LEDs and correspondent detectors, apparently, the IR touchscreen solution is more cost-effective in large interactive displays, such as the interactive digital board, which are used for presentation in business meetings.

With the belief of continuous improvement and sincere service, we have provided satisfactory Infrared Touch Frame to more customers at home and abroad. The out frame of the infrared touch using alluminum material, which is strong and durable, not including glass. It adopts light-resistant design, can be applied to internal and external link environments, and is widely used in touch screen displays, touch all-in-one machines, touch kiosks, touch digital signage, touch whiteboards, etc.
