Specifically, the active reflection screen display module further includes: the rear cover 900 is embedded in the first step 816 and the second step 866, and is tightly matched with the supporting frame 800, so as to seal, prevent water or prevent insects of the whole structure of the active reflection screen display module.
The active reflection screen display module further comprises: the main board 620 is disposed on the back of the reflective screen 600 in a direction of the second side supporting portion 860, and is connected to the main board terminal hole 871, so as to facilitate data transmission. The rear cover 900 of the active reflection screen display module can be further provided with an appearance bracket or a wall-hanging screw hole, so that the active reflection screen display module can be conveniently hung on a wall. The active reflecting screen display module is internally provided with a gravity sensor, has symmetrical appearance, can automatically identify the transverse screen and the vertical screen and realize matched display, and can realize free switching of the transverse screen and the vertical screen.
Embodiment III:
on the basis of the first embodiment and the second embodiment, in a specific embodiment structure of the present invention, the present invention provides a display device, including an active reflection screen display module as described in the first embodiment and the second embodiment. Through the arrangement, the display device uses the glass light guide plate to integrate the light guide plate with the front cover plate, so that a frame adhesive tape between the light guide plate and the front cover plate is omitted, the glass light guide plate is fully attached to the reflecting screen, after the reflecting screen returns light, the light can directly enter human eyes through the glass light guide plate, the number of intermediate transmission links is reduced, the light loss is reduced, the whole visual effect is transparent, in addition, the mesh points of the glass light guide plate which are arranged in a small mesh point and low density can be improved, and the picture quality is high.
In summary, according to the active reflective screen display module and the display device provided by the invention, the supporting frame 800 includes the side supporting portion 801, and the first strip-shaped plate 811 connected to the front end of the side supporting portion 801, so that the side supporting portion 801 surrounds the mounting cavity, the reflective screen 600 is disposed in the mounting cavity, and the glass light guide plate 700 is disposed on the light emitting side of the reflective screen 600 and is attached to the reflective screen 600, so that the first strip-shaped plate 811 is disposed at the light emitting side edge of the glass light guide plate 700, not only is the reflective screen 600 disposed in the mounting cavity surrounded by the supporting frame 800, but also the glass light guide plate 700 can be compressed, thereby increasing the firmness of the active reflective screen display module, and also combining the light guide plate 300 with the front cover plate 100, omitting the adhesive tape 200 between the light guide plate 300 and the front cover plate 100, so that after the reflective screen 600 returns light, the light can directly enter the human eyes through the glass light guide plate 700, reducing the number of intermediate transmission links, and improving the overall visual quality. The problems of excessive light loss and illusion of the visual effect of the display screen caused by too many passing media in the transmission process of the light rays of the active reflecting screen are solved.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
