Abstract
An ultra-thin light guide plate for an LCD screen of a mobile phone is disclosed, aiming at an ultra-thin light guide plate which realizes the ultra-thinning of the display screen of the mobile phoneto ultimately realize the ultra-thinning of the mobile phone. The guide light plate comprises a light-emitting face towards an LCD and a grid face opposite to the light-emitting face; the ultra-thin light guide plate is characterized in that: the upper edge of the light guide plate is provided with a sawtooth projecting edge which includes a triangular tooth peak and a reversely-trapezoidal toothvalley; the grids shaped as a rhombic structure are distributed on the light guide plate in the manner of variable distance/variable point, equal point/variable distance or equal distance/variable point.
Description
Technical field
The utility model relates to a kind of display screen light guide plate, especially a kind of ultra-thin light guide board that is used for mobile phone display screen.Belong to field of photoelectric technology.
Background technology
Along with improving constantly of continuous advancement in technology and living standard, mobile phone has become indispensable communication tool in people's life, colour screen handset is abundant because of its pattern color, not only have visual joyful, more because can reach more function, satisfied the fastidious taste of user and follow the fashion, personalized demand.The user of a very big mobile phone wishes that mobile phone is done thinlyyer, power consumption still less.And the critical component of restriction mobile phone thickness is a display screen, and display screen comprises LCD and backlight, and the size of LCD has been determined by glass substrate; Backlight is made up of outward appearance double faced adhesive tape, reflector plate, glue frame, light guide plate, circuit unit, diffusion sheet, time brightening piece, last brightening piece, black and white double faced adhesive tape.The critical component that wherein restricts the backlight thickness is a light guide plate, because light guide plate is thin more, how the light that light source penetrates just in the difficult more arrival light guide plate, produces ultra-thin light guide plate, all is that production firm wishes the difficult problem that solves for a long time.
Summary of the invention
The purpose of this utility model provides a kind of ultra-thin light guide board, realizes ultra-thinization of mobile phone display screen, finally realizes ultra-thinization of mobile phone.
The technical scheme that its technical matters that solves the utility model adopts is: light guide plate includes an exiting surface and a site face relative with exiting surface towards LCD, of the present utility model being characterised in that: the light guide plate upper edge has the serrate convex edge, described serrate convex edge tooth cutting edge of a knife or a sword is a triangle, and tooth paddy is for trapezoidal; On the face of described site the rhombus site is arranged, the rhombus site on the light guide plate mesh point face, adopt the displacement height, etc. some displacement or equidistant height mode distribute.
So-called displacement height, the area that means single site and the distance between the site become (or diminishing) greatly from an end of light guide plate successively to the other end; Point displacements such as what is called mean that the area of single site is identical, and the distance between the site becomes (or diminishing) greatly from an end of light guide plate successively to the other end; So-called equidistant height means that the distance between the site is identical, but the area of single site becomes (or diminishing) greatly with a end from light guide plate successively to the other end.
The beneficial effects of the utility model are: incident ray is fully spread, and feasible from light source emergent light intensity enhancing at a distance, surface, entire backlight source distribution of light is more even.Therefore can make light guide plate and backlight do very thinly, thereby realize ultra-thinization of mobile phone display screen.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model mobile phone light guide panel;
Fig. 2 is that the utility model is sought tabula rasa top serration structural representation.

Among the figure, 3. are convex edges, 4. are site faces, the 41st, the site, 5. be the tooth peak, 6. be tooth paddy, 7. be the outward appearance double faced adhesive tape, 8. be reflector plate, 9. are glue frames, 10. are light guide plate, the 11.th, circuit unit, the 12.th, diffusion sheet, the 13.th, following brightening piece, the 14.th, last brightening piece, the 15.th, black and white double faced adhesive tape, the 16.th, backlight.
Embodiment
Referring to accompanying drawing, the utility model light guide plate includes an exiting surface and a site face relative with exiting surface towards LCD, it is characterized in that: light guide plate 10 upper edge have serrate convex edge 3, and the tooth cutting edge of a knife or a sword 5 of described serrate convex edge 3 is a triangle, and tooth paddy 6 is for trapezoidal; On the described site face 4 rhombus site 41 is arranged, rhombus site 41 on site face 4, adopt the displacement height, etc. some displacement or equidistant height mode distribute.
In embodiment of the present utility model, serrate convex edge 3 its space widths of light guide plate 10 upper edge are about 0.08mm.In first embodiment, site 41 is adopted on site face 4 and is waited the some displacement: site height 0.02mm, and site length of side 0.02mm, the rhombus angle is respectively 90 degree, arranged to the afterbody dot matrix from light source direction beginning site 41, and spacing is ascending from 0.02mm ~ 0.04mm left and right sides to increase progressively change.In a second embodiment, equidistant height is adopted in site 41: site height 0.02mm, the site begins to arrange to the afterbody dot matrix from light source direction, spacing fixedly 0.02mm is constant, site length of side 0.02mm ~ 0.04mm, the rhombus angle is respectively 90 degree, the length of side of rhombus site from 0.02mm beginning ascending increasing progressively change to 0.04mm.In the 3rd embodiment, the displacement height is adopted in site 41: site height 0.02mm, site rhombus angle is respectively 90 degree, the site begins to arrange to the afterbody dot matrix from light source direction, the site spacing increases progressively change from 0.02mm ~ 0.04mm is ascending, simultaneously the length of side of rhombus site from the 0.02mm beginning ascending increasing progressively change to 0.04mm.
During use, the light that the LED lamp on backlight 10 circuit units sends in the broached-tooth design 3 through the light guide plate top, can change the direction of propagation of light, and light spreads apart to all directions; For making the light guide plate leaded light evenly and improve back light source brightness, after light enters light guide plate, reflect through the refraction of site, light guide plate bottom veil point 41 again, make light light up and down meet through outward appearance double faced adhesive tape 7, the reflector plate 8 that black and white double faced adhesive tape 15 fits together, diffusion sheet 12, following brightening piece 13, the time spent of doing of last brightening piece 14 further reflects reflection, make light up and down fully return in the light guide plate, the light at directive edge is through being in the glue frame 9 inwall reflected back light guide plate, utilize light source more fully, also guaranteed the illumination effect of backlight.
The broached-tooth design at the utility model light guide plate top and the design of the lattice point structure of bottom surface of light guide plate, make the light source incident ray after the refraction reflection, fully be spread, whole light guide plate and backlight surface light is evenly distributed, and has saved the energy content of battery when having improved the illuminating effect of LCD.The high meter of such structure can be so that light guide plate reaching evenly, is accomplishing 0.3mm under the prerequisite of adequate illumination effect, realizes ultra-thinly, satisfies market more to the frivolous portable characteristic demand of mobile phone.
