Controlling Color and White Temperature in an LCD Display Modulating Supply Current Frequency

摘要

A display system, having an emissive body, emitting light in a way that is color temperature controllable. The light emission can be from zones. The emissive body can be a FIPEL type device with a first transparent conductive coating over a light emitting substrate. The zones are each separately controllable for color temperature.

主权项

1. A display system, comprising
an emissive body, divided into sections including at least first and second sections, and emitting light from at least one surface, said emissive body receiving a color temperature control that controls multiple different color temperatures of said light, where each of the sections has their color temperature separately controlled by said color temperature control; and a spatial light modulator, having multiple individual controllable pixels, said multiple pixels being illuminated by said emissive body, and said pixels each modulating the light from said emissive body to produce a display, where said first and second sections of said emissive body illuminate the spatial light modulator with different color temperatures in different areas.
