The system of High Dynamic Range Display based on the dual structure of the LCD-FED

High Dynamic Range display can reproduce a dynamic range of luminance from the real setting. The systems of High Dynamic Range Display based on the dual structure of the projector or LED array have many shortcomings, such as huge volume and low local contrast. In this paper a new backlight of liquid crystal display based on Field Emission Display is proposed. The method in this paper has the advantages of raising local contrast and dodging the halo and eliminating motion artifacts of LCD HDR display. The experiment result indicates that it has higher practical value since the field emission backlight structure can increase the local contrast to 2¹⁶∶1.
