Abstract:
A liquid crystal display (LCD) is configured for use in a head mounted display (HMD) to increase the brightness and improve power consumption of the LCD by recycling light. The LCD includes a color filter (CF) substrate, a thin film transistor (TFT) substrate, and a backlight unit (BLU). The CF substrate is closer to the BLU than the TFT substrate. The CF substrate includes a first reflective layer in regions of the CF substrate between pixels to reflect light back towards the BLU to be recycled to increase the brightness of the LCD. The TFT substrate includes TFTs to drive the pixels and a second reflective layer covering TFTs to reflect light away from the TFTs.
