Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an ultra-thin double-sided screen assembly. Background Art

[0002] The window display products face the street on one side and the indoors on the other. Since the outdoor brightness is high and the indoor brightness is low, the display screen facing the street needs to have high brightness, while the display screen facing the indoors only needs low brightness to make it comfortable for human eyes to watch. The double-sided screens currently used in this occasion all use two module screens installed back to back. The one facing the street uses a high-brightness screen, and the one facing the indoors uses a low-brightness screen. However, such double-sided screens are too thick and heavy to be easy to install and carry, and the cost is relatively high. Utility Model Content

[0007] The reflective sheet is arranged between the two light guide plates, both sides of the reflective sheet are provided with coatings, and the two light guide plates are bonded to the coatings on both sides of the reflective sheet through OCA.

[0008] The beneficial effect is that when the ultra-thin double-sided screen assembly of the utility model is used, firstly two rows of LEDs of different specifications are installed in the installation groove at intervals, and then the reflective sheet is clamped between the two light guide plates, and then the two light guide plates can be inserted into the installation groove between the two installation plates, and then the LED is turned on, and the light emitted by the LED is emitted into the light guide plate, and when the light is reflected on the reflective sheet, it can be reflected back to the corresponding light guide plate, so that the two light guide plates do not affect each other. When the ultra-thin double-sided screen assembly of the utility model is used, the structure is simple, and it is convenient to install and carry. At the same time, the thickness is only the thickness of two light guide plates, which reduces the occupied space and reduces the cost.

[0034] The two fixing plates 12 are provided with limiting grooves on opposite sides thereof, and the space between the two limiting grooves and the two mounting grooves 3 forms a mounting cavity.

[0035] There are two light guide plates 5, which are slidably assembled in the above-mentioned installation cavity, and the two light guide plates 5 are arranged one by one corresponding to the two rows of LEDs 4. Both light guide plates 5 are against the lower end of the partition block 9, and the upper end of each light guide plate 5 is also against the corresponding end of the installation block 7.
