Abstract
A backlight module comprises a light guide plate and organic light-emitting diode lamp strips arranged in the side direction of the light guide plate. The backlight module has the better light-emitting quality.
Description
Technical field
The present invention relates to a kind of backlight module, relate in particular to a kind of OLED backlight module.
Background technology
Than traditional light emitting source, the advantage such as that light emitting diode (Light Emitting Diode, LED) has is lightweight, volume is little, it is low to pollute, the life-span is long, it is applied in the middle of each field more and more as a kind of novel light emitting source.
Yet the backlight module of liquid crystal panel generally includes some light emitting diodes that a LGP and is arranged on this LGP one side.Light emitting diode is a side that is one by one arranged in LGP, and leaves gap between adjacent light emitting diode.Due to the existence in gap, between adjacent light emitting diode, will produce blanking bar, cause the luminescent quality of liquid crystal panel not good.Even if adopt LGP to carry out mixed light to light emitting diode, in the position of the incidence surface near LGP, still have blanking bar and occur.
Summary of the invention
Given this, the present invention aim to provide a kind of can not produce blanking bar backlight module.
A backlight module, comprises a LGP and is located at the organic light emitting diode lamp bar that one of this LGP side direction is continuous distributed.
Because Organic Light Emitting Diode is continuous distributed, therefore there is not the problem of blanking bar, thereby make the luminescent quality of this backlight module better.
Accompanying drawing explanation
The schematic perspective view of the backlight module that Fig. 1 provides for a preferred embodiment of the present invention.
Fig. 2 is the top view of Fig. 1.
Main element symbol description
The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
The schematic perspective view of the backlight module 1 that a preferred embodiment that Fig. 1 provides by the present invention.The organic light emitting diode lamp bar 20 that backlight module 1 comprises a LGP 10 and is arranged on a side direction of LGP 10.
LGP 10 is that a thin type is dull and stereotyped, and it has relatively and a upper surface 11 and a lower surface 12 of be arrangeding in parallel, and four sides 13 that connect upper surface 11 and lower surface 12.In the present embodiment, side 13 is vertical with lower surface 12 with upper surface 11 respectively.
Please refer to Fig. 2, organic light emitting diode lamp bar 20 is arranged at a side 13 of LGP 10 and arranges with these 13 intervals, side.Organic light emitting diode lamp bar 20 has a substrate 21 and is arranged on the Organic Light Emitting Diode that is continuous distributed 22 on substrate 21, and this Organic Light Emitting Diode 22 is over against this side 13 of LGP 10.
Organic Light Emitting Diode 22, by the indium tin oxide (ITO) of a thin and transparent tool characteristic of semiconductor, is connected with the positive pole of power supply, adds another metal negative pole, is bundled into the structure as sandwich.Organic Light Emitting Diode 22 also comprises hole transmission layer (HTL), luminescent layer (EL) and electron transfer layer (ETL).When power supply supply appropriate voltage, anodal hole and negative pole electronics just can combinations in luminescent layer, generation photon.Material behavior according to the luminescent layer of Organic Light Emitting Diode 22 is different, produces red, green and blue RGB three primary colors, forms basic color.Because Organic Light Emitting Diode 22 is to be continuous distributed, so it can not produce blanking bar in luminous process, can effectively improve the luminescent quality of backlight module 1.At organic light emitting diode lamp bar 20, in manufacturing process, be to utilize the technique of evaporation to make.In evaporate process, it is improper that the color material of Organic Light Emitting Diode 22 each pixels may be controlled, and causes, between neighbor, the phenomenon of colour mixture to occur, thereby make Organic Light Emitting Diode 22 that colour cast occur.But due to the existence of LGP 10, the light that Organic Light Emitting Diode 22 sends can pass through the mixing of LGP 10 and eliminate colour cast.Therefore, backlight module 1 of the present invention also can further be eliminated the problem of colour cast.Understandably, organic light emitting diode lamp bar 20 also can be located at the not ipsilateral 13 of LGP 10.
Technology contents of the present invention and technical characterstic disclose as above, yet those skilled in the art still may be based on teaching of the present invention and announcements and made all replacement and modifications that does not deviate from spirit of the present invention.Therefore, protection scope of the present invention should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present invention and modifications, and is contained by appended claim.
