Abstract

The embodiment of the invention provides a display device which comprises a light-emitting unit, a backlight unit, a pixel array, and a pixel drive unit. The light-emitting unit is arranged on one side of the backlight unit and used for emitting light to the backlight unit, the pixel array is arranged on the backlight unit and comprises a plurality of pixel units, the pixel drive unit is used for obtaining an image to be displayed and generating control commands for all pixel units according to the image to be displayed, the backlight unit is used for sending light emitted from the light-emitting unit to the pixel array, and each pixel unit determines the passing rate of light sent by the backlight unit at the corresponding pixel unit according to the control commands.

Description

technical field [0001] Embodiments of the present invention relate to a display device. Background technique [0002] With the continuous development of science and technology, various terminal electronic devices such as personal computers, portable computers, smart phones, multimedia players, and e-books have been proposed. Users can easily use these terminal devices to watch videos, browse web pages, make video and audio calls, etc. With the widespread use of these electronic devices, display technology has become a current research hotspot. [0003] At present, liquid crystal display technology is still the mainstream display technology. However, when the liquid crystal display device displays images, it is first necessary to polarize the light from the backlight unit through a polarizer to obtain polarized light with a specific polarization direction, and a large amount of energy of the light from the backlight unit is lost in the process. Then it is modulated by anot...
