Problems solved by technology

[0003] However, the current image display devices all switch between the scattering state and the transparent state by periodically controlling the display screen, so that when the projector projects an image, the control display screen is all switched to the scattering state, and when the projector is not projecting , to switch all the display screens to a transparent state, the stage or display effect is relatively simple, and the display effect of combining virtual and real cannot be realized

Abstract

The invention provides a display device and a display method. The display device comprises a display curtain, a projection machine and a control mechanism, wherein the display curtain comprises at least two sub-display areas, each sub-display area can be independently driven so that each sub-display area can be switched between a scattering state and a transparent state; the projection machine is used for projecting an image on the display curtain; and the control mechanism is used for synchronously driving the projection machine and the display curtain to control at least a part of the sub-display areas to be switched in the scattering state or the transparent state respectively according to the projected image of the projection machine. According to the display device provided by the invention, the display curtain of the display device can realize that a part of the sub-display areas are in the scattering state so as to realize projection display and a part of the subs-display areas are in the transparent state, so that actual scenes are watched, the illusion of vitality and reality combined display in the air is realized, and more abundant stage or display effect is realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method. Background technique [0002] In the prior art, an image display device realizes display by projecting an image from a projector onto a display screen that can be switched between a transparent state or a scattering state. The image display device can be applied on the stage. When an image needs to be displayed, the display screen is switched to a scattering state, and the projector projects an image on the display screen to realize the display. For the audience, there is a feeling of display in the air; When displaying images, the display screen is switched to a transparent state. Through the lighting effect, the surrounding area is blocked, and the audience cannot see any medium. The audience can watch the programs on the stage or watch the displayed products through the display screen. [0003] However, the current image display...
