摘要： An LCD display system provides colored backlighting to enhance the viewing experience of presentations by the display system. The liquid crystal display (LCD) system includes a monochrome LCD to display monochrome information including at least two sectors; at least two backlighting elements to emit light in a plurality of colors, each backlighting element associated with one sector of the LCD and configured to backlight the one associated sector with a color light; and a processing device to control display of the information on the LCD and to select the color emitted by each backlighting from the plurality of colors. Each backlighting element may include two or more different color light emitting diodes (LEDs) wherein the intensity of each color LED is controlled by the processing device to provide the color selected by the processing device. A reflective element may be positioned relative to the backlighting element to reflect the color light emitted by the backlighting element. A diffusing element may be positioned between the backlighting element and the LCD.

摘要翻译： LCD显示系统提供彩色背光以增强显示系统的演示的观看体验。 液晶显示（LCD）系统包括单色LCD以显示包括至少两个扇区的单色信息; 至少两个背光元件以多种颜色发光，每个背光元件与所述LCD的一个扇区相关联并且被配置为用彩色光背光所述一个相关联的扇区; 以及处理装置，用于控制LCD上的信息的显示，并且从多种颜色中选择由每个背光发出的颜色。 每个背光元件可以包括两个或更多个不同的彩色发光二极管（LED），其中每个彩色LED的强度由处理装置控制以提供由处理装置选择的颜色。 反射元件可以相对于背光元件定位以反射由背光元件发出的彩色光。 漫射元件可以位于背光元件和LCD之间。
