	Infrared (IR)	Projected Capacitive (PCAP)
Same size Cost	Lower cost	Size bigger cost higher
Touch Screen Control Type	a finger , or other solid objects	Can sense proximity of finger.

Durability	Good	Good
Impact Ball Drop Test	Yes	Yes , cover glass are all tempered glass
Scratch Resistance
Life time	Depend on IR tube quality
