    • A light emitting diode includes a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region, and n- and p-contacts disposed on the n- and p-type regions. The light emitting layer is configured to emit light of a first peak wavelength. A wavelength converting material is positioned in a path of light emitted by the light emitting layer. The wavelength converting material is configured to absorb light of the first peak wavelength and emit light of a second peak wavelength. The light emitting diode is configured such that a light emission pattern from the light emitting diode complements a light emission pattern from the wavelength converting material.

    • One or more LEDs are mounted within an LCD without the use of any printed circuit board (PCB), thus reducing the thickness of the LCD by about the thickness of the conventional PCB. In one embodiment, the LED and submount are mounted so that the submount is opposing the liquid crystal layer side of the LCD, so that the liquid crystal layers provide the mechanical support for the submount and LED die. The LED die (mounted on the submount) may be inserted into a cavity formed in the “top” surface of the light guide, and the top surface of the light guide is abutted against the liquid crystal layers. In such a configuration, the LED light source, including all supporting components, adds no thickness to the LCD. In another embodiment, on the “bottom” surface of the LCD opposing the LED die is an electrically switchable mirror that is either reflective or transparent. In its transparent state, the LED in the LCD may be used as a flash in a cell phone camera, while the LCD may be viewed to take the picture.
    • 一个或多个LED安装在LCD中,而不使用任何印刷电路板(PCB),从而将LCD的厚度减小约传统PCB的厚度。 在一个实施例中,安装LED和基座,使得底座与LCD的液晶层侧相对,使得液晶层为子安装座和LED管芯提供机械支撑。 LED模具(安装在基座上)可以插入到形成在导光体的“顶部”表面中的空腔中,并且导光体的顶表面与液晶层抵接。 在这种构造中,包括所有支撑部件的LED光源不向LCD增加厚度。 在另一个实施例中,在与LED管芯相对的LCD的“底部”表面上是可反射或透明的可电换镜。 在其透明状态下,LCD中的LED可以用作手机相机中的闪光灯,而LCD可以被观看拍摄照片。
