|1. (WO2017152519) STEREOSCOPIC DISPLAY DEVICE|
|Applicants:||BOE TECHNOLOGY GROUP CO., LTD.
|Title:||STEREOSCOPIC DISPLAY DEVICE|
A stereoscopic display device, comprising: an imaging space (30), which is internally provided with an up-conversion material; a first light source (10), which emits light towards the imaging space (30) along a first direction; and a second light source (20), which emits light towards the imaging space (30) along a second direction, wherein when the stereoscopic display device works, light from the first light source (10) and light from the second light source (20) intersect in the imaging space to form a light convergence line or convergence plane, so that the corresponding up-conversion material on the convergence line or within the convergence plane is activated to emit light. The stereoscopic display device can realize planar or linear scanning of the up-conversion material in the imaging space (30), and can greatly reduce the high scanning speed required in a conventional point-by-point scanning mode, so that the quality of a displayed image can be improved.
