Abstract
The utility model relates to the technical field of electronic display screens, in particular to a front and back sided LED display screen. The front and back sided LED display screen comprises a light guide plate, as well as a first LCD and a second LCD which are respectively arranged on the front surface and the back surface of the light guide plate, wherein a first diffusion film, a first brightness enhancement film and a third diffusion film are sequentially attached between the light guide plate and the first LCD; a second diffusion film, a second brightness enhancement film and a fourth diffusion film are sequentially attached between the light guide plate and the second LCD. According to the utility model, as the mode that the diffusion films and the brightness enhancement films are arranged between the light guide plate and the LCDs replaces the traditional mode that lighting board substrates are adopted in a single-sided display screen and a double-sided display screen, the thickness and the size of the display screen are greatly reduced, and reduction of the manufacturing cost is facilitated; meanwhile, a double-screen driver board and an LED light bar can be respectively driven by a power panel to achieve the energy-saving effect; in addition, the double-screen driver board can be synchronously driven or asynchronously driven according to the actual conditions; the front and back sided LED display screen has a simple structure and very strong practicability.
Description
Technical field
The utility model relates to electronic display technical field, two-sided display screen before and after especially a kind of LED.
Background technology
Along with scientific and technological development, LED display has been widely used in the various places such as bank, airport, station, market, bus platform, car exhibition, houses selling office, hotel, to play the effects such as ad distribution, net cast, information inquiry, information bulletin and sign.
At present, LED display on the market is mostly that one side shows, is arranged on LED in LED display for display text, and it is more single that display effect seems, do not reach the advertising results of expection.For this problem, the bilateral structure of the disclosed LED display of Chinese utility model patent CN202662242U, the disclosed a kind of dual surface LED display screen of Chinese utility model patent CN202549199U and the disclosed a kind of double-side liquid crystal display screen of Chinese invention patent CN101158781A, tool has proposed the technical scheme of two-sided display screen, that is: a light guide plate before, rear surface is disposed with respectively one deck lighting material thin layer, a plane skylight substrate and a liquid crystal display, thereby realize two-sided display screen, but whole display screen causes the thickness of display screen further to reduce owing to being provided with plane skylight substrate, screen volume and weight is bigger than normal, high expensive.
Therefore, be necessary existing two-sided display screen to make further architecture advances, so that screen is thinner, volume and weight is less, cost is lower, installs and use convenient.
Utility model content
The purpose of this utility model is to provide a kind of LED front and back two-sided display screen, can realize on the basis of double-sided display, overcomes many deficiencies that existing one side display screen and two-sided display screen exist.
To achieve these goals, the utility model adopts following technical scheme:
A two-sided display screen before and after LED, it comprises a light guide plate, the first liquid crystal display that is placed in respectively light guide plate front and rear surfaces and the second liquid crystal display, is pasted with successively the first diffusion barrier, the first brightness enhancement film and the 3rd diffusion barrier between described light guide plate and the first liquid crystal display; Between described light guide plate and the second liquid crystal display, be pasted with successively the second diffusion barrier, the second brightness enhancement film and the 4th diffusion barrier.
Preferably, described light guide plate is formed by two organic glass adhesions that are oppositely arranged, and is provided with several light guiding points on the opposite face of described organic glass.
Preferably, it also comprises LED lamp bar, and described LED lamp bar is arranged at the incidence surface of light guide plate.
Preferably, it also comprises power panel and double screen drive plate, described power panel be electrically connected respectively double screen drive plate and LED lamp bar, and described double screen drive plate drives the first liquid crystal display and the second liquid crystal display.
Preferably, described double screen drive plate is synchronous drive plate or asynchronous drive plate.
Owing to having adopted such scheme, the utility model adopts and by the mode of diffusion barrier and brightness enhancement film is set between light guide plate and liquid crystal display, replaces adopting in traditional one side display screen and two-sided display screen the mode of plane skylight substrate, reduced greatly the thickness of display screen, reduced the volume of display screen, be conducive to reduce production costs; Meanwhile, can drive respectively double screen drive plate and LED lamp bar to reach energy-conservation effect by power panel; In addition, double screen drive plate can adopt synchronous driving or asynchronous driving according to actual conditions; It is simple in structure, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the electrical connection schematic diagram of part parts of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, two-sided display screen before and after a kind of LED of the present embodiment, it comprises a light guide plate 1, the first liquid crystal display 2 that is placed in respectively light guide plate 1 front and rear surfaces and the second liquid crystal display 3, is pasted with successively the first diffusion barrier 4, the first brightness enhancement film 5 and the 3rd diffusion barrier 6 between light guide plate 1 and the first liquid crystal display 2; Between light guide plate 1 and the second liquid crystal display 3, be pasted with successively the second diffusion barrier 7, the second brightness enhancement film 8 and the 4th diffusion barrier 9, with this, utilize the diffusion barrier of increase and brightness enhancement film to replace the plane skylight substrate in traditional one side display screen or two-sided display screen, to reduce the thickness of whole display screen, make its thickness can be down to 9mm left and right, also reduced the volume of display screen simultaneously.
Further, transparent organic glass adhesion that the light guide plate 1 of the present embodiment is oppositely arranged by two, high forms, on the opposite face of organic glass, by light guide ink, be printed with several different light guiding points (not shown)s, with this, increase the performance of light guide plate 1, and reduce the integral thickness of light guide plate 1.
The display screen of the present embodiment also comprises LED lamp bar 10, and LED lamp bar 10 is arranged at the incidence surface of light guide plate 1, can arrange according to actual conditions, as adopted the mode attaching.
On the basis of the above, the display screen of the present embodiment also comprises power panel 11 and double screen drive plate 12, wherein, and power panel 11 be electrically connected respectively double screen drive plate 12 and LED lamp bar 10, think that both power, and utilize double screen drive plate 12 to drive the first liquid crystal display 2 and the second liquid crystal display 3.
For expanding the scope of application of display screen, the double screen drive plate 12 of the present embodiment can adopt synchronous drive plate or asynchronous drive plate, can be by install Android system on double screen drive plate 12, to realize before and after display screen in the simultaneous display of two sides the perhaps function of asynchronous display, owing to adopting, the volume of double screen drive plate 12 of Android system is very little, and more stable than more power saving of common PC, system, be conducive to improve the overall performance of display screen.
