摘要：
We propose a high dynamic range (HDR) liquid crystal display (LCD) with pixellevel local dimming. The device structure consists of a pixelated LCD dimming panel to control the backlight intensity entering the master LCD panel. According to our analysis and test cell experiment, this dual-panel display system possesses exceedingly high contrast ratio (> 1,000,000: 1) and high bit-depth (> 14 bits) at merely 5 volts. Meanwhile, to mitigate the Moire effect induced by the cascaded thin-film transistor (TFT) backplanes, we separate the two LCD panels with a polarization-dependent scattering film. The pros and cons of this HDR display are discussed. (C) 2017 Optical Society of America
