Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1-2, the convertible back lighting display provided by this embodiment includes a display housing 1, a fixing frame 11 is provided in the display housing 1, a PCB 111 is fixedly installed on one side of the fixing frame 11, a plurality of LED lamps 112 are installed on the PCB 111, a light guide plate 113 is provided on the other side of the fixing frame 11, the light guide plate 113 is fixedly installed on the edge of the fixing frame 11, the light guide plate 113 is directly opposite to the plurality of LED lamps 112, a display screen 123 is provided on one side of the display housing 1 close to the light guide plate 113, and the display screen 123 is detachably connected to the display housing 1.

In practical use, at the side-mounting LED lamp 112 of display screen 123, increase light guide plate 113 simultaneously between LED lamp 112 and display screen 123, the light that LED lamp 112 sent reflects to display screen 123 through the leaded light piece after the refraction on, strengthens display screen 123 edge area's luminance, effectively solves the trailing phenomenon, realizes the effect of the different background light of transform through adjusting the colour that transforms LED lamp 112 simultaneously.

In the present embodiment, the plurality of LED lamps 112 are uniformly distributed on the outer side of the fixing frame 11, so that light emitted from the LED lamps 112 is irradiated onto the light guide plate 113.

In this embodiment, the PCB 111 and the light guide plate 113 are respectively and fixedly connected to the display housing 1, so as to prevent the imaging effect of the display screen 123 from being affected by the position change of the PCB 111 and the light guide plate 113 in actual use.

In this embodiment, the display housing 1 is internally and fixedly mounted with two L-shaped gaskets 12, the two L-shaped gaskets 12 are symmetrically disposed, the L-shaped gasket 12 includes a first side plate 121 and a second side plate 122, a pressing block 1212 is disposed on the first side plate 121, and the pressing block 1212 is connected to the first side plate 121 through a spring hinge 1211.
