| 摘要 | An example micro-projection-display device includes: a projection lens, an elastic projection screen, a stretchable projection framework and a sliding block. At least one point of the stretchable projection framework is connected with the elastic projection screen, so that the stretchable projection framework is configured to control the elastic projection screen to stretch or retract. The sliding block is connected with the stretchable projection framework. The sliding block is configured to cause the stretchable projection framework to stretch or retract, so as to cause the elastic projection screen to stretch or retract. The projection lens is configured to project light onto the stretched elastic projection screen. | ||
