What on Your Display?

Users often are unaware of how harmful Blue Light technology, emitted from a device can be. Dr Chris Bai spoke to him about its importance, colour accuracy for professionals and what sets BenQ apart from other companies. Excerpts:

- Dr Chris Bai, Chief Colour Scientist, BenQ Global

You’ve patented and worked on the (Low) Blue Light technology at BenQ, which is critical. How did that happen?

Over 10 years ago, we observed that blue light’s effects on people's daily lives. Hence, we introduced the low blue light technology, initially it was the first gen, which eventually turned into the second generation. The difference between the first and second generation is that the latter was a hardware-based solution. We fine-tuned all the LED wavelengths so you don’t get distorted colour temperature. It’s not going to be yellowish, but you still get the benefit of having a good colour and picture quality and more importantly people can have a good night’s sleep.

This was important. In terms of colour science, why are accurate colours important for both a consumer and a professional?

These are two very different aspects we're looking at. For the consumer, they don’t really care about the colour reproduction because they look at colours from a fashion colour perspective, which are more saturated, more pleasing to the eye. They don’t care if this red or this green looks correct or not.
