Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] The embodiment of the present invention provides two kinds of display devices, one display device performs display through a display screen, a projector and a control module, and the other display device performs display through a display screen, a light source and a control module.

[0042] Wherein, the projector can emit light of any color at the same time. When the target image is displayed by the projector, light of different colors can be simultaneously emitted according to the color of each pixel in the target image, thereby forming the target image on the display screen.

[0043] The light source can only emit light of one color at a time. When the target image is displayed through the light source, the light source emits ...

Abstract

The invention discloses a display device and an image display method, and belongs to the technical field of display. The method comprises a display screen, a projector and a control module. The display screen comprises a liquid crystal layer. The liquid crystal layer comprises a plurality of liquid crystal molecules. The control module is electrically connected to the projector and the display screen. The control module is configured to determine a display area of the display screen according to the pixel value and the position of each pixel in a target image. The projector is configured to emit a light beam of a corresponding color to a corresponding area in the display screen according to a color indicated by the pixel value of each pixel. The control module is further configured to control the liquid crystal molecules in the display area in a disordered state in order to scatter the light beams emitted to the liquid crystal molecules on the display area to constitute the target image in the display area. Because of the high light utilization rate of the display area, the brightness of the target image is increased. There is no case where most of the light passes through the display area, thereby avoiding bright spots on the ground in front of the display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and an image display method. Background technique [0002] With the development of display technology and the gradual improvement of users' requirements for display effects, a new display method has been proposed, which can display images on a curtain with a certain transparency rate. When users watch images, they can create a kind of image suspension. displayed effect. The display method is novel and unique, and has been welcomed by the majority of users. [0003] In the related art, a display device includes a high-transparency curtain, a projector, and a reflector. The projector and the reflector are located on the rear side of the high-transparency curtain, and the projector is opposite to the reflector. The projector is used to obtain the image to be displayed, and determine the required light color according to the color information of the image, so as ...
