Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
Example one
One embodiment of the semi-transparent display screen device of the invention is shown in fig. 1 and 2, and is installed on a shielded door 1 of a subway, wherein the shielded door 1 comprises a plurality of pieces of shielded glass 13, steel columns 12 are arranged on both sides of the shielded glass 13, a door ridge beam 11 is arranged above the shielded glass 13 and the steel columns 12, a transparent display screen 2 is arranged on the shielded glass 13, a control device 3 is arranged on the door ridge beam 11, and the control device 3 is connected with the transparent display screen 2.
The transparent display screen 2 comprises an aluminum alloy frame 21 and a plurality of plates, wherein the plates comprise a first tempered glass plate 22, a transparent liquid crystal panel 23 and a light guide plate 24 which are sequentially arranged from front to back; first toughened glass board 22, transparent liquid crystal display panel 23 and light guide plate 24 all set up in aluminum alloy frame 21, and each limit of first toughened glass board 22, transparent liquid crystal display panel 23 and light guide plate 24 all with aluminum alloy frame 21 fixed connection. The first tempered glass plate 22 is a transparent tempered glass plate, and the light guide plate 24 is a transparent acrylic plate. The outermost layer of the transparent display screen 2 is a first tempered glass plate 22 which has good collision resistance and friction resistance.
Specifically, the thicknesses of the first tempered glass plate 22, the transparent liquid crystal panel 23 and the light guide plate 24 are all less than 5mm, so that each plate can be bent to a certain extent; the gaps between the layers of each plate are set between 0.2 and 1mm, so that the total thickness is less than 20 mm. When the plates (the shielding glass 13) vibrate, the damage of the vibration to the plates can be reduced through certain physical deformation, and the gaps can prevent the plates from generating unnecessary friction when deforming.
Preferably, the thicknesses of the first tempered glass plate 22, the transparent liquid crystal panel 23 and the light guide plate 24 are all set between 4 and 5mm, so that unnecessary weight is prevented from being excessively increased, physical toughness of each plate can be prevented from being influenced by excessively small thickness, and the impact resistance of the first tempered glass plate 22 is ensured. The clearance setting between each plate layer is between 0.5 to 0.8mm, except can avoiding unnecessary friction between each plate, can also avoid the unable radiating problem of clearance undersize.
The inner sides of two or four corresponding sides of the aluminum alloy frame 21 are also provided with mounting seats 211, the mounting seats 211 are respectively provided with a plurality of mounting grooves, the mounting grooves sequentially comprise a first toughened glass plate mounting groove 212, a transparent liquid crystal panel mounting groove 213 and a light guide plate mounting groove 214, and the positions of the mounting grooves are mutually corresponding; each mounting groove in the mount pad is glued through the heat conduction respectively and the plate fixed connection that corresponds, makes inside heat (including the heat that transparent liquid crystal display panel 23 during operation produced) can conduct aluminum alloy frame 21 through the heat conduction and give off, reaches better radiating effect in transparent display screen 2.
The rear side of the aluminum alloy frame 21 is fixedly connected with the shielding glass 13 through the heat insulation glue layer 28, the heat conducted to the aluminum alloy frame 21 can be prevented from being conducted to the shielding glass 13 through the heat insulation glue layer 28, and meanwhile the heat insulation glue layer 28 cannot lose adhesion capacity due to long-term thermal aging.
Further, the transparent display 2 is further provided with a light guide lamp, and the light guide lamp 251 or 25 is disposed above the light guide plate 24 or above between the transparent liquid crystal panel 23 and the light guide plate 24. The light guide lamp 24 is an LED lamp group consisting of a plurality of LED lamps, and the light guide lamp 251 or 25 is connected to the projection module. The light guide lamp 251 or 25 is in a normally bright state, and the display effect of the transparent display screen 2 is enhanced. In addition, when no train enters the station, the transparent display screen 2 has a perspective effect due to the fact that light ray differences exist between the inner side and the outer side of the shielding glass 13.
Example two
As shown in fig. 1 and 3, the main technical solution of this embodiment is substantially the same as that of embodiment 1, and features not explained in this embodiment adopt the explanations in embodiment 1, and are not described again here. This example differs from example 1 in that:
the plurality of plates of the transparent display screen 2 further comprise a second tempered glass plate 221, and the transparent liquid crystal panel 23 and the light guide plate 24 are both arranged between the first tempered glass plate 21 and the second tempered glass plate 24; the mounting groove of the mounting seat 211 is further provided with a second tempered glass plate mounting groove 215 corresponding to each other in position.
Further, the transparent display 2 is further provided with a reinforcing lamp 26, and the reinforcing lamp 26 is disposed above the second tempered glass plate 221 and the light guide plate 24. The reinforcing lamp 26 is an LED lamp set consisting of a plurality of LED lamps, and the reinforcing lamp 26 is connected to the projection module. When no train enters the station, the reinforcement lamp 26 is in a normally closed state; when the train arrives at the station, the reinforcing lamp 26 in the transparent display screen 2 is turned on by the control device 3. Because the light ray difference is eliminated at the inner side and the outer side of the shielding glass 13, the condition that personnel in a train can see a platform through the transparent display screen 2 can be ensured only by turning on the reinforcing lamp 26. Similarly, after the train leaves the station, the information transmission module receives the train leaving signal sent by the display screen management platform, and the reinforcing lamp 26 in the transparent display screen 2 is turned off through the control device 3, so that the effects of saving energy and reducing heat generation are achieved.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
