Abstract: A display device includes a display panel; a collimation film structure and a liquid crystal lens structure sequentially arranged on a light exit side of the display panel; and an eye tracking unit for determining a position of a viewer in front of the liquid crystal lens structure. Specifically, the collimation film structure is configured to collimate light emitted from the display panel to form a collimated light. The liquid crystal lens structure is configured to redirect the collimated light towards the position determined by the eye tracking unit. By determining light emission directions of each sub-pixel in the display panel through eye tracking techniques and enabling the light converged on a position accepted by human eyes, light utilization is effectively improved and power consumption is reduced.

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.

Abstract: A display device is disclosed. The display device includes a display panel, and a grating layer arranged inside or outside of the display panel. Along a direction pointing from a center of a sight concentration area of the display device to a non-sight concentration area of the display device, a grating period of the grating layer decreases gradually. When incident light incident on the grating layer is diffracted at an area of the grating layer corresponding to the non-sight concentration area of the display device, the obtained light of non-zero order diffraction falls into a sight of a viewer.
