Further, the length direction of described U-type groove is consistent with the thickness direction along light guide plate.
Further, described light guide plate is rectangular shape.
Further, the thickness of described light guide plate is between 0.2mm to 0.6mm.
Further, described light guide plate is transparent plastic article.
Further, the edge of described light guide plate is provided with shading rubber belt.
For solving the problems of the technologies described above, the invention allows for a kind of display screen structure, comprise above-mentioned guiding device, the upper surface of described guiding device is provided with an anti-dazzle rete, and the lower surface of described guiding device is provided with optical-grade double-side glue-line down stacked successively, touch surface flaggy, gelatine layer and monochrome inks display screen.
Technique scheme at least has following beneficial effect: the present invention adopts transparent light guide plate, is provided with LED winding displacement at the side of light guide plate, and LED winding displacement is provided with the LED lamp bead of a row towards light guide plate internal illumination.By light guide plate, the spot light of LED is converted to area source, be arranged on when electric book reader uses, can be implemented in the object without also reading when external light source.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment one
As shown in Figure 1, the guiding device of the embodiment of the present invention comprises the transparent light guide plate 1 of rectangular shaped, the thickness of light guide plate 1 is between 0.2mm to 0.6mm, preferably, employing thickness is the transparent plastic light guide plate of 0.45mm, be provided with LED winding displacement 3, LED winding displacement 3 at a side of light guide plate 1 and be provided with the LED lamp bead 2 of a row towards light guide plate 1 internal illumination.By light guide plate 1, the spot light of LED lamp bead 2 being converted to area source, when being used on electric book reader, electric book reader can be realized when without the object also can read when external light source.
As another kind of embodiment, as shown in Figures 2 to 5, focal point 4 is provided with on the surface of light guide plate 1, concrete, focal point 4 is distributed in light guide plate surface with the situation of concave point, and focal point, except density program difference, also has between focal point each point and adjusts setting with certain optical principle formula, light guide plate is the acrylic/PC sheet material utilizing optical grade, passes through mould molding.The light utilizing optical grade acrylic/PC sheet material to draw to send from LED lamp bead 2 is in the stop of optical grade acrylic/PC plate surface, when light is mapped to each light guiding points, reverberation can toward all angles diffusion, then the injection path of light is changed, luminous energy is upwards spread, reaches the object that all angles can be luminous.By various density, focal point 4 not of uniform size, light guide plate 1 uniformly light-emitting can be made, therefore, focal point 4 from LED lamp bead 2 distance more away from layout more intensive, nearly LED lamp bead 2 is consistent with light guide plate 1 brightness away from LED lamp bead 2 place, reaches the uniform effect of whole screen light.
As shown in Figure 5, the side that can also be positioned at LED lamp bead 2 light inlet at light guide plate 1 is provided with U-type groove 5, breaks up in rear importing light guide plate 1 by U-type groove 5 by LED lamp bead 2 light source, promotes the uniform effect of whole panel light further; Preferably, the length direction of U-type groove 5 and the thickness direction along light guide plate 1 are consistent, the side being positioned at LED lamp bead 2 light inlet at light guide plate 1 is provided with row's U-type groove 5, and adjacent two U-type groove 5 are connected mutually, like this spot light of LED lamp bead 2 is transferred to the effect of uniform area source significantly good.The edge of light guide plate 1 is provided with shading rubber belt 6, makes the light-emitting zone of light guide plate 1 periphery evenly regular.
Embodiment two
As shown in Figure 6, the display screen structure of the embodiment of the present invention comprises above-mentioned guiding device 20, the upper surface of guiding device 20 is provided with an AGFilm anti-dazzle rete 10, and the lower surface of guiding device 20 is provided with OCA optical-grade double-side glue-line 30 down stacked successively, TP touch surface flaggy 40, OCR gelatine layer 50 and EPD monochrome inks display screen 60.
Adopt guiding device as built-in light source, by light guide plate 1, the spot light of LED lamp bead 2 is converted to area source, reach the effect that light source is provided, be applicable to the reading of electric paper book, solve the problem that electric book reader can not be read a book when light is dark, make electric book reader when light is dark, open LED lamp bead 2, still can read.
The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
