These 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/segment is lit causing the area of intersection to emit light. The atomic layer deposition (ALD) enables very precise thin films – a nanometre thick – ensuring reliable, rugged displays with unique transparency and performance capabilities.
These displays have an extremely wide operating temperature range of -60°C to 105°C with a response time of 1 ms regardless of the temperature. They are shock and vibration tolerant with a 200g force shock durability for the glass and 100g for the complete unit. 85% of original brightness remains after 100,000 hours of usage and they also have high contrast and wide viewing able of 179°.
