INFRARED VISION WITH LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
Various embodiments related to infrared vision for a liquid crystal display (LCD) device are disclosed herein. For example, one disclosed embodiment provides a display system, comprising an LCD device and a display backlight configured to illuminate the LCD device by directing visible light toward an interior surface of the LCD device. The display system further comprises a wavelength-selective reflector disposed between the display backlight and the LCD device and having a smooth surface facing the interior surface of the LCD device, where the wavelength-selective reflector has a wavelength-selective coating configured to cause incident visible light from the display backlight to be transmitted through the wavelength-selective reflector to the LCD device, and cause incident infrared light reflected from an object on or near an exterior surface of the LCD device to be reflected off of the wavelength-selective reflector and directed to an infrared vision subsystem. |
