Abstract
The utility model discloses an electronic paper display device which comprises a thin film baseplate, electronic paper positioned on the thin film baseplate, and a protecting film positioned on the electronic paper. A light source is arranged on at least one side edge of the electronic paper, a light guide plate contacted with the light source is arranged on the protecting film, a transparent light source substrate is further arranged above the light source and the light guide plate, and the conductive circuit contacted with the light source is printed on the side edge of the light source substrate. The electronic paper display device has the advantage that electronic paper can be displayed even without an external light source.
Description
Technical field
The utility model belongs to technical field of electronic components, relates in particular to a kind of display device of electronic paper.
Background technology
At present electronic paper technology is used in a lot of fields to some extent because Electronic Paper is to manifest by reflect ambient light, so in the sun or the high place of brightness be particularly suitable for using Electronic Paper to shield.But the defective of Electronic Paper screen is when having external light source, can't not show, this has greatly weakened the utilization rate of Electronic Paper screen under no external light source condition.
The utility model content
The utility model technical matters to be solved provides a kind of at the display device of electronic paper that does not have also can show under the external light source condition, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of display device of electronic paper; Comprise the film base plate, be positioned at the Electronic Paper on the film base plate and be positioned at the diaphragm on the Electronic Paper; It is characterized in that: the said at least one side of Electronic Paper that is positioned at is along light source is set; Said diaphragm top also is provided with light source and contacts LGP, and said light source and LGP top also are provided with transparent light source substrate, and said light source substrate side is printed with the conducting wire that contacts with light source.
In the embodiment of the utility model, said light source is positioned at edge, the Electronic Paper left and right sides.
In the embodiment of the utility model, said light source is a plurality of LED lamps, and this LED lamp is spaced apart.
Adopt technique scheme,, can not have under the external light source condition like this, open light source and pass through LGP, thereby literal and pattern on the Electronic Paper can be seen at the Electronic Paper surface light emitting through light source being set on Electronic Paper side edge.
Therefore, the display device of electronic paper of the utility model has the advantage that also can show under the external light source condition not having.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Among the figure:
100-film base plate, 200-Electronic Paper, 300-diaphragm, 400-LED light source, 500-LGP, 600-light source substrate.
Embodiment
As depicted in figs. 1 and 2, the display device of electronic paper of the utility model comprises film base plate 100, Electronic Paper 200, diaphragm 300, led light source 400, LGP 500 and light source substrate 600.
Wherein, Film base plate 100 is positioned at the bottom; Electronic Paper 200 is positioned on the film base plate 100; Diaphragm 300 is being positioned on the Electronic Paper 200, and Electronic Paper 200 left and right sides are distributed with a plurality of led light sources 400, and LGP 500 is arranged on diaphragm 300 tops and contacts (being in particular on the last corner that led light source 400 is positioned at LGP 500) with led light source 400.Light source substrate 600 is a transparent membrane, is positioned at the top of LGP 500 and led light source 400, and the position of the corresponding led light source 400 of light source substrate 600 dual-sides is printed with the conducting wire with led light source 400.
More than be exactly the display device of electronic paper of the utility model, this display device of electronic paper has the advantage that also can show under the external light source condition not having.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (3)
