Driver IC receives image data and delivers precise analog voltages or currents to activate the pixels on the display.
When voltage is applied to the liquid crystal within each pixel cell, the liquid crystal is bent, thereby changing the intensity of light that passes through each individual pixel.
VCSEL (IR Light Source)
The vertical-cavity surface-emitting laser, or VCSEL is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer
a logic gate is a physical device implementing a Boolean function. Logic gates are using diodes or transistors acting as electronic switches. Most gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).
InP-based lasers are formed from alloys of the same constituents, Ga, Al, In and As, P, but in compositions that are lattice-matched to InP. They range from about 1100 to 2000 nm, but by far the most common are emitters at 1300, 1480 and 1550 nm, which are used in fiber optic communications
