Novel LCDs with IR-sensitive backlights

摘要: — In this paper, a novel multi-touch LCD architecture with hover-sensing capability is described. To detect multiple touch points and hover simultaneously, sensitive backlight, which backlight integrated an IR sensor array, introduced. The uses visible light to display contents on screen also used reflected from objects or near the screen. captured image extract information. proposed maintains slim form factor of no loss quality, while making it possible sense touches hovers simultaneously.
