With Charge-type architecture, GLS6155 comes with features of high sensitivity and extremely low dark current noise. Through high-speed sampling, it captures the blanking of the screen in a very short period. Thus, it minimizes the interference of screen light and allows hardware-level high-precision measurement of correlated color temperature and illuminance. It also supports algorithm-based screen light interference reduction solution, which allows software-level high-precision measurement of correlated color temperature and illuminance. Placing LED or VCSEL in the ultra-narrow bezel of a device allows unrestricted proximity sensing; if the LED or VCSEL light source is placed under the screen, proximity sensing in the off-screen state can be achieved, and the proximity sensing in the on-screen state can be achieved with screen touch controller.
