摘要 | A display apparatus for producing colored pixelated light includes a backlight unit for producing pump-beam light and a vertical cavity laser array device including a structure for modulating the properties of the device at spaced locations so as to provide an array of spaced laser pixels which have higher net gain than the interpixel regions, and an active region which includes portions for producing different colored light in response to the pump-beam light. The apparatus also includes a light shutter and a beam expander disposed over the light shutter for increasing the angular cone of view of the selected colored light. |
其他摘要 | 一种用于产生彩色像素化光的显示装置,包括用于产生泵浦光束的背光单元和包括用于在间隔位置调制装置特性的结构的垂直腔激光器阵列装置,以便提供具有间隔开的激光像素阵列。比像素间区域更高的净增益,以及包括响应于泵浦光产生不同颜色光的部分的有源区域。该装置还包括光闸和设置在光闸上方的光束扩展器,用于增加所选彩色光的角锥视角。 |
