We have been reporting on Hong Kong-based LED developer, Deepsky, for a couple of years partly because it is one of the suppliers that can achieve high brightness at small LED pitch. At the show, it was claiming peak brightness of 2,500 cd/m² at the show, with 3,000 cd/m² under development based on ‘virtual pixels’ of 0.9mm (the company has its own sub-pixel arrangement). The company will also introduce 1.1mm and 1.6mm configurations later this year.
The company has been developing chip-on-board (COB) LED technology based on its own driver technology which is able to support up to 16 bit content and ‘true’ HDR. The company’s drivers are based on a special ‘high level’ LVDS scheme and the company showed us (but wouldn’t let us photograph) how its chips are directly integrated onto the back of the individual modules which are very thin. The control of the drivers is done on a GPU in a PC to perform colour correction and calibration. The matrix of the display is all passive.
Deepsky told us that it has developed its own placement machinery to create the modules in its display based on its own robotic technology. The firm is also optimistic that its developments will allow it to get access to special LEDs, later, which will improve the colour performance of its displays even further.
