The LED-backlit module of the LCDs of prior art is because LED-backlit lamp source is distributed in four sides of glue frame 110 backlight conventionally, need to could realize uniformly light-emitting by means of diffusing panel 108, light guide plate 109, reflecting plate 111, therefore, LED-backlit module is comprised of diffusing panel 108, light guide plate 109, reflecting plate 111, glue frame 110 backlight and LED-backlit lamp source conventionally, so thickness is thicker, quality is also larger, does not meet the day by day frivolous requirement of current LCDs.
Summary of the invention
In view of this, the embodiment of the present invention proposes a kind of LCDs, can realize the frivolous property of LCDs.
The embodiment of the invention discloses a kind of backlight module for LCDs, comprise:
Electroluminescent light source plate, is evenly provided with organic electroluminescence device, and described electroluminescent light source plate is as the backlight source of described LCDs.
Preferably, described organic electroluminescence device comprises Semiconductor substrate and is positioned at the organic electroluminescent device in described Semiconductor substrate.
Preferably, described backlight module also comprises FPC, for giving described organic electroluminescence device power supply.
Preferably, described FPC is arranged on the side of electroluminescent light source plate.
Preferably, described backlight module also comprises organic electroluminescence glue frame backlight.
The present invention has also offered a kind of LCDs, comprises above-mentioned backlight module and thin film transistor (TFT) module.

The embodiment of the present invention is by being used electroluminescent light source plate to replace the backlight source that LED lamp source shows as liquid crystal layer, can realize and send out uniformity of light, and need not adopt diffusing panel, light guide plate and reflecting plate, can reduce quality and the thickness of whole LCDs, thereby realize the frivolous property of LCDs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the LCDs of prior art;
Fig. 2 is the LCDs of the embodiment of the present invention and the structural representation of backlight module.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate technical scheme of the present invention.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, in accompanying drawing, only show part related to the present invention but not full content.
Fig. 2 is the LCDs of the embodiment of the present invention and the structural representation of backlight module.As shown in Figure 2, the embodiment of the present invention provides a kind of backlight module for LCDs, include organic electro luminescent light source board 208, electroluminescent light source plate 208 is evenly provided with organic electroluminescence device 2081, and described electroluminescent light source plate 208 is as the backlight source of described LCDs.
Wherein, because organic electroluminescent is that face is luminous, and evenly arrange, therefore organic electroluminescence device 2081 is luminous even, realized a uniformity of light, and organic electroluminescence device 2081 is evenly arranged on electroluminescent light source plate 208, so the backlight module for LCDs of the embodiment of the present invention is luminous more even than prior art.
Wherein, electroluminescent light source plate 208 has a plurality of organic electroluminescence devices, and organic electroluminescence device 2081 comprises Semiconductor substrate and is positioned at the organic electroluminescent device in described Semiconductor substrate.The basic structure of organic electroluminescent device belongs to sandwich type structure conventionally, and luminous material layer is by both sides electrode holder in centre, and a side is that transparency electrode is luminous with acquisition face.Wherein, luminous material layer is divided into high-molecular luminous material and the large class of low mulecular luminescence material two conventionally, and low mulecular luminescence material mainly contains fluorescent material and phosphor material.Suitable electrode while adding the DC voltage of 2-5 volt on film (1/10000mm) plated surface being formed by special photism material, this film will send light, and this process is called electroluminescence (Electroluminescence is called for short EL).Due to the frivolous important feature of organic electroluminescent device, the material that has determined it must be processed and is attached in Semiconductor substrate by film, and electroluminescent organic material can be attached on Semiconductor substrate by film adherence methods such as chemical vapor deposition (CVD) or physical chemistry vapour depositions (PVD).
