RDS Releases Transparent Lumineq Touch Displays

Transparent touch displays with Lumineq Touch Technology built in are now available from Review Display Systems (RDS). Enabled by atomic layer deposition (ALD), these displays can be used in applications where fully transparent properties are required.

“Anywhere there is glass, there is an opportunity for integrating these touch-enabled displays,” the company said.

The Lumineq Transparent Thin Film Electroluminescent displays (TASEL) consist of a solid-state glass panel and an electronic control circuit. The glass panel consists of a luminescent phosphorous layer sandwiched between transparent dielectric layers and conductive ITO electrodes.

By applying voltage to the electrodes, a pixel or segment is lit, causing the area of intersection to emit light. The ALD enables very precise thin films – a nanometer thick.

Fully integrated into the transparent displays, this new touch technology does not affect the thickness, weight, complexity or make it less durable. An In-Cell PCAP is used where the touch sensors are integrated directly into the existing functional layers of the display technology, which means there are no additional layers.

The touch-sensitive areas use existing indium tin oxide (ITO) layers.
