Abstract

Examples of the present disclosure relate to a device, method, and system for optical input diodes. A liquid crystal display (LCD) backlight device may include a processor and a color filter of a pixel including at least one of a red filter, a green filter, or a blue filter. The LCD backlight device may also include a diode to emit light through the color filter in response to being driven by the processor. The diode may generate a voltage in response to light passing through the color filter and arriving on the diode, where an image value may be calculated as a function of the voltage generated and a color filter value of the color filter.
