Abstract: An optical assembly, a display device and a method for driving the same are provided. The optical assembly includes two substrates disposed opposite to each other, and electrodes are disposed on the two substrates respectively. Voltages are applied to the electrodes to form a transverse electric field being configured for driving liquid crystal molecules proximal to the substrates to deflect, so that liquid crystal proximal to the two substrates both form liquid crystal lenses, thereby forming a double-layer liquid crystal lens structure. Since the two substrates of a liquid crystal cell have high alignment accuracy, the electrodes on the two substrates are consistent in spatial distribution, thereby solving mura problem.

Abstract: A 3D display device and a method of driving the same are disclosed in the present disclosure. An electroluminescence display panel instead of a conventional backlight module is adopted to be arranged behind the liquid crystal display panel. In the 3D display mode, light emitting areas and black areas alternately arranged in both the row direction and the column direction are formed in the electroluminescent display panel, so that an abnormal grating structure is formed. In the 3D display mode, the first sub-pixels corresponding to the same light emitting area are controlled to display different gray level information so that the left and right eyes of a person located at two viewpoints receive an image of different gray level information. Therefore, stereoscopic vision is created and a naked-eye 3D display at the sub-pixel level is achieved.
