The display device at least comprises a base provided with a containing space, a support member vertically arranged on the base, two light guiding plates respectively arranged at the two sides of the support member, at least two light sources respectively arranged at one side edge of the light guiding plates, two liquid crystal display (LCD) modules respectively arranged at one side of the light guiding plates and two front frames (Beze1) respectively covered on the circumference of the two LCD modules.

Description

The display device of two-sided screen
Technical field
The invention relates to a kind of display with double faces, and particularly relevant for a kind of liquid crystal indicator of two-sided screen.
Background technology
Flourish along with display technique, and, developed the liquid crystal indicator that to have two-sided screen at present in response to the various demand of information service.Because therefore the liquid crystal indicator double-sided display type picture of two-sided screen can make the broadcast or the display area expansion multiplication of display device, and then can significantly promote the effectiveness of display device.
Generally speaking, assemble the display device with double-sided display screen, existing technology and way with two ready-made monitor modules, assemble in back-to-back mode usually.So, formed display device is double-sided display type not only, more can show different picture images on two each and every one screens.
Yet, assembling the display device that forms by two ready-made monitor modules, unitary construction can be too huge, and the thickness that causes device is greatly.In addition, the printed circuit board (PCB) of two monitor modules needs to bend toward the back side from the lower edge of monitor module, and is fixed on the back side of monitor module.Thus, not only can further increase the thickness of display device, more can increase puzzlement, and be unfavorable for volume production the assembling of display device.
Summary of the invention
Therefore, purpose of the present invention is exactly that a kind of display device of two-sided screen is being provided, and the printed circuit board (PCB) of its display module can directly be arranged in the base, and assembling quite easily is so help volume production.
Therefore another object of the present invention is a kind of display device of two-sided screen to be provided, can to omit reflector plate, and only uses a slice light guide plate, not only can reduce the technology cost, but the thickness of reduction device also makes device more light and handy.
Above-mentioned purpose according to the present invention proposes a kind of display device of two-sided screen, and comprise at least: base has an accommodation space; Supporting member, upright being located on the base; Two light guide plate are located at the both sides of supporting member respectively; At least two light sources are located at respectively on the side of above-mentioned light guide plate; Two LCD MODULE are located at a side of above-mentioned light guide plate respectively; And two preceding frames (Bezel), be located at respectively on the periphery of aforementioned two LCD MODULE.
According to one embodiment of the present invention, also comprise two reflector plates at least, be located at respectively between two light guide plate and the supporting member.In addition, each LCD MODULE includes printed circuit board (PCB), extends and descends from the lower edge of LCD MODULE, and be arranged in the accommodation space of base.
According to purpose of the present invention, a kind of display device of two-sided screen is proposed, comprise at least: base has an accommodation space; Supporting member is located on the base; Light guide plate is located among the supporting member; At least one light source is located on the side of light guide plate; Two LCD MODULE are located at the both sides of light guide plate respectively; And two preceding frames, be located at respectively on the periphery of LCD MODULE.
According to one embodiment of the present invention, above-mentioned supporting member is a chase, is located on the periphery surface of light guide plate, to clamp light guide plate.Wherein, chase preferably is located at the central authorities of the periphery surface of light guide plate, separates into two parts that essence equates with the periphery surface with light guide plate.In addition, above-mentioned at least one light source preferably includes two cold cathode fluorescent lamp, on two parts that are separated out with the periphery surface genital areas of being located at light guide plate respectively.
Owing to only needing by means of a supporting member, can developing separately in the both sides of this supporting member one group of display screen, therefore can effectively reduce the thickness of display device.In the another kind design, more single light guide plate can only be set, with the thickness of further reduction display device.In addition, the printed circuit board (PCB) of LCD MODULE can directly be arranged among the base from the LCD MODULE extension, therefore can remove that printed circuit board (PCB) is bent in the program at the LCD MODULE back side from, not only assembling easily more can further be dwindled the thickness of display device.
