In a specific embodiment of the present invention, as shown in fig. 2, the active reflective screen display module further includes: and two light bar assemblies 400, the two light bar assemblies 400 are respectively arranged on the upper side and the lower side of the glass light guide plate 700 along the length direction. The lamp bar assemblies 400 are arranged on the upper side and the lower side of the glass light guide plate 700, so that the using quantity of the lamp bar assemblies 400 is saved, and the energy consumption is also saved. Specifically, as shown in fig. 8, the light bar assembly 400 includes: light bar plate 410 and lamp beads 420. The light bar plate 410 is arranged along the length direction of the glass light guide plate 700, a plurality of light beads 420 are arranged on the light bar plate 410 at intervals, and the light emitting directions of the light beads 420 face the direction of the glass light guide plate 700. The lamp beads 420 emit light laterally, and compared with a forward light emitting mode, the whole structure is more compact. Thus, the light emitted from the lamp beads 420 can be directly transmitted through the glass light guide plate 700. It is easy to think that the light emitting direction of the lamp bead 420 can also be set in the form of a straight light emitting angle. One side of deviating from lamp pearl 420 direction on the slat 410 is provided with plug wire interface 430, plug wire interface 430 specifically sets up in the third recess 817, plug wire interface 430 is used for giving lamp pearl 420 supplies power, also makes simultaneously plug wire interface 430 avoids glass light guide plate 700 does benefit to the light conduction.
In the structure of the specific embodiment of the present invention, as shown in fig. 9, a reinforcing strip plate 610 is disposed on one side of the reflective screen 600 away from the glass light guide plate 700, and two reinforcing strip plates 610 are disposed to reinforce the overall strength of the active reflective screen display module, and may also be used as a carrier for hanging a wall or a bracket. Specifically, the active reflection screen display module further includes: and the rear cover 900 is clamped and embedded in the first step 816 and the second step 866, is tightly matched with the supporting frame 800, and is used for sealing, waterproofing or preventing insects of the integral structure of the active reflective screen display module.
The active reflective screen display module further comprises: and a main board 620, wherein the main board 620 is disposed on the back of the reflection screen 600 in a direction facing the second side supporting part 860 and is connected to the main board terminal hole 871 to facilitate data transmission. An appearance support or a wall-hanging screw hole can be further formed in the rear cover 900 of the active reflection screen display module, so that the active reflection screen display module can be hung on a wall conveniently. The gravity sensor is arranged inside the active reflection screen display module, the appearance of the gravity sensor is symmetrical, transverse and vertical screens can be automatically identified and matched for display, and free switching of the transverse and vertical screens is achieved.
Example three:
on the basis of the first embodiment and the second embodiment, in the structure of the specific embodiment of the present invention, the present invention provides a display device, including the active reflective screen display module according to the first embodiment and the second embodiment. Through the setting, display device uses the glass light guide plate is with two unifications of light guide plate and front shroud, has saved the frame between light guide plate and the front shroud and has pasted the adhesive tape, the glass light guide plate with the reflecting screen is laminated entirely for the reflecting screen returns the back with light, via the glass light guide plate, alright direct entering people's eye has reduced the quantity of middle transmission link, makes the light loss reduce, and whole visual effect is penetrating, and in addition, little site, low density are arranged the glass light guide plate site can improve holistic permeability, and the picture quality is high.
In summary, according to the active reflection screen display module and the display device provided by the present invention, the supporting frame 800 includes the side supporting portion 801 and the first bar-shaped plate 811 connected to the front end of the side supporting portion 801, such that the side supporting portion 801 surrounds the mounting cavity, the reflection screen 600 is disposed in the mounting cavity, the glass light guide plate 700 is disposed on the light emitting side of the reflection screen 600 and attached to the reflection screen 600, such that the first bar-shaped plate 811 is disposed at the light emitting side edge of the glass light guide plate 700, and not only the reflection screen 600 is disposed in the mounting cavity surrounded by the supporting frame 800, and the glass light guide plate 700 can be compressed, thereby increasing the firmness of the active reflection screen display module, but also the light guide plate 300 and the front cover plate 100 are integrated into one, and the frame adhesive tape 200 between the light guide plate 300 and the front cover plate 100 is omitted, after the light is returned by the reflecting screen 600, the light can directly enter human eyes through the glass light guide plate 700, the number of intermediate transmission links is reduced, the light loss is reduced, the visual effect is transparent, and the whole picture quality is improved. The problems of excessive light loss and unreal display screen image visual effect caused by too many passing media in the transmission process of the light of the active reflecting screen are solved.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
