SiliconCore will debut its ZACH LED driver chip, the result of three years of R&D, at InfoComm 2017.
ZACH stands for Z(Impedance) Adjustment for Colour Homogeneity.
The ZACH mechanism embedded in the driver chip can detect impedance variation of each LED and apply an adjustment compensation. This achieves uniform brightness and homogeneous colour at low brightness levels.
This product series launch will be aimed at cinema, command and control and simulation environments.
Showcased as a 4K 1.2mm LED Display at InfoComm 2017, the ZACH chip enables SiliconCore displays to provide accurate colour reproduction in the areas of low brightness. Combined with SiliconCore’s Common Cathode Technology (CCT) this 4K screen can achieve uniform maximum brightness of over 1,800Nits and minimum brightness under 0.1Nits. The effective dynamic range is over 18,000 to 1 or over 14 bits. Reproduction of colour can be achieved way beyond rec 2020 colour bit depth which is fast becoming the industry standard.
SiliconCore displays Lavender 1.2mm, Magnolia 1.5 and Camellia 0.95 will be the first displays to ship with the new ZACH LED drivers in July.
