Have you been facing difficulty reading displays in bright sunlight? Not anymore. A D Metro has overcome this issue by introducing the advanced IR- Infrared touchscreens. Linear Correlating Infrared Touch Technology (LCIR) is one of A D Metro’s patented innovations, raising the capabilities of the touchscreen industry. The LCIR touch technology surpasses and overcomes all the limitations of the standard IR-infrared touchscreens, offering advanced attributes to touch applications. It has greatly benefitted two crucial industries- aviation and automotive, where intense sunlight interferes with display viewing.
This LCIR utilizes innovative optics and signal processing to seamlessly deliver multi-touch functionality in applications exposed to intense or strobing sunlight with superior optical clarity and negligible radio frequency (RF) emissions. Hence, making applications safe and efficient to use in bright sunlight environments.
Features of A D Metro’s LCIR Touch Technology
Zero-Force Two-Touch Input:
Linear correlating infrared (LCIR) touch technology provides highly responsive, precise, glove-compatible, two-touch, zero-force operation. As no substrate glass covers the display, LCIR touch sensors maintain the display’s optical performance, which is very important in automobiles and aviation.
The LCIR touch sensors can provide two-touch functionality by performing optical scans at various angles over the touch detection area. This is a fantastic feature for applications that require pinch, zoom, and rotate capabilities but struggle to integrate projected capacitive (PCAP) touch sensors. They offer touch input compatibility with gloved fingers and a 5mm stylus.
Immunity to Strobing Light:
What makes LCIR touchscreens stand out from their counterparts is- their consistent performance in high-intensity light from any direction with 100% sunlight immunity. They remain unaffected by bright light, and the screen displays information with 100% optical clarity/maximum contrast.
Considering the traditional IR/ infrared touchscreens, they are designed as rectangular sensor frames with LEDs and photodetectors surrounded by a bezel or cover. However, A D Metro’s LCIR touch sensors are engineered to offer intrinsic benefits of flawless light transmission, minimum radio emissions, unlimited glove compatibility, high radio interference tolerance, and compatibility with severe temperatures and pressures.
Reliability and Touch Precision:
LCIR touchscreens integrate linear correlation techniques to communicate via optical signals across numerous points on the display’s surface, unlike standard infrared touchscreens that use single-point IR beams. This contributes to exceptional reliability and touch accuracy.
Available Options:
A D Metro’s patented LCIR touch technology includes a sensor frame and a controller board. Furthermore, there are several alternatives for connecting the controller board to the system. USB is conventional (communicates with many operating systems without requiring a driver), but RS-232 (low voltage) and I2C are also available.
In Conclusion:
Overall, A D Metro’s LCIR touchscreens are ideal for applications to be used in bright light or strobing sunlight, for example, automotive and aviation applications. They are preferred over projected capacitive (PCAP) touchscreens for applications facing difficulty integrating PCAP touch panels due to radio emission susceptibility or severe design limits concerning display visibility or glove compatibility.
LCIR touchscreens, on the other hand, offer optical clarity with maximum contrast even in strobing sunlight, responsiveness, precision, and reliable two-touch functionality with gloved fingers, making them an excellent choice for demanding applications.
