TMD3721

ALS/Color and Proximity Sensor

Module for Behind OLED Applications

The TMD3721 features ambient light, color (RGB) sensing and

proximity detection. The device integrates an IR VCSEL and an

advanced VCSEL driver within a compact

4.65mm x 1.86mm x 0.90mm OLGA package.

The ambient light and color sensing function provides four

concurrent ambient light sensing channels: Red, Green, Blue,

and Clear. The RGB and Clear channels are covered with an UV/IR

blocking filter. This architecture accurately measures ambient

light and enables the calculation of illuminance and color

temperature to manage display appearance.

The proximity function synchronizes IR emission and detection

to sense nearby objects. The architecture of the engine features

self-maximizing dynamic range, ambient light subtraction,

advanced crosstalk cancellation, and interrupt-driven I²C

communication. Sensitivity, power consumption, and noise can

be optimized with adjustable IR VCSEL timing and power. The

proximity engine recognizes detect/release events and

produces a configurable interrupt whenever the proximity

result crosses upper or lower threshold settings.
