| description | The invention provides a three-dimensional display. The three-dimensional display comprises a linear Fresnel lens, a liquid crystal panel, a lenticular grating, a solid-state light source, a synchronous driving unit and an image source, wherein the lenticular grating comprises a plurality of lenticular units, the solid-state light source is provided with a first stripped light source group and a second stripped light source group corresponding to each lenticular unit, the image source is connected with the liquid crystal panel and the solid-state light source through the synchronous driving unit, and is used for providing a left eye image and a right eye image in frame sequences for the liquid crystal panel, and the synchronous driving unit is used for selectively controlling the ON of the first light source group or the second light source group of the solid-state light source according to the frame sequences of the left eye image and the right eye image. According to the three-dimensional display provided by the invention, the synchronous driving unit controls the ON of the first light source group and the second light source group in the solid-state light source respectively according to time sequence of the image frame, so that each lenticular unit can be used for separating a light path according to the time sequence, the linear Fresnel lens is used for converging time-sequence light paths separated from a grating of a microlens, and therefore the three-dimensional display of an image can be realized. |
