How does TASEL Touch Technology Work?

Transparent TASEL with touch interaction may have you thinking it must be a complicated process but let us explain to you that it is not.

Lumineq Transparent Thin Film Electroluminescent displays (TASEL) comprise a solid-state glass panel and electronic control circuit. The glass panel consists of a luminescent phosphorous layer sandwiched between transparent dielectric layers and conductive ITO electrodes. A pixel/segment is lit by applying voltage to the electrodes, causing the area of intersection to emit light.

The functional thin film layers are manufactured using ALD. ALD enables very precise nanometer–thick, pinhole–free and totally conformal thin films making the Lumineq transparent displays reliable and inherently rugged with unique transparency and performance characteristics.

The new Lumineq Touch technology is fully integrated into the segmented Lumineq transparent display technology and does not make the display glass panel any thicker, heavier, complex or any less durable.

Lumineq Touch uses unique In-Cell PCAP where the touch sensors are integrated directly in the already existing functional layers of the display technology.

There are no additional layers, as the touch sensitive areas use the existing indium tin oxide (ITO) layers that are used for the electroluminance display.
