Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 5, a no glue frame for ultra-narrow backlight, no glue frame body is including setting up at the left side chase 2 of backlight visual area 1, setting up at the right side chase 3 on backlight visual area 1 right side and setting up at the day side chase 4 of backlight visual area 1 upside, left side chase 2, right side chase 3 and day side chase 4 all include chase body 5, shading glue and press diaphragm 7, diaphragm 8 and light guide plate 9, light guide plate 9 sets up on chase body 5, diaphragm 8 sets up on light guide plate 9, one side of chase body 5 is equipped with the portion of bending of U type, leave the clearance between portion of bending and the diaphragm 8, shading glue and press diaphragm 7 to set up on portion of bending and diaphragm 8.
Further, the length of the bending part of the iron frame body 5 is three times of the thickness of the iron frame body 5.
As shown in fig. 2 and 6, after the positions of the glue-removing frame 6 are taken from the left and right sides of the visible area 1 of the backlight source, the current thickness D of the flat plate/notebook bezel material is 0.15mm (min), the C value needs to be 3 times the thickness of the bezel material and is 0.45mm, the assembly gap E between the LGP (light guide plate 9) and the bezel body is 0.15mm (min), the gap G between the diaphragm 8 and the bezel body 5 is 0.25mm (currently, 11 inches or less), and the minimum value of the light-shielding glue-pressing diaphragm 7 can be 0.30mm (min), that is, the F value is 0.4mm, and a + D + B + F is 0.15+0.35+0.4 + 0.9 mm.
As shown in fig. 7, after the position of the bezel is removed on the backlight day side of the visible area 1 of the backlight source, the thickness D of the current flat plate/notebook bezel material is 0.15mm (min), the value C needs to be 3 times the thickness of the material and is 0.45mm, the value D of the assembly gap between the LGP and the bezel is 0.15mm (min), the value G of the gap between the diaphragm and the bezel is 0.25mm (currently, 11 inches or less), the value G of the light-shielding adhesive pressure diaphragm can be 0.30mm (min), and the value a is C + D + E is 0.15+0.30+0.45 and is 0.9 mm.
As shown in fig. 3, in the prior art, the value C of the wall thickness of the left and right side bezel of the backlight is made to be 0.45mm at minimum, the value B of the gap between the LGP (light guide plate) and the bezel becomes larger as the product becomes larger (especially as the long side enters the light product), at present, the value below 11 inches is 0.25mm, the distance a from the backlight outline to the v.a area (visible area of the backlight source) is 0.3mm at minimum, therefore, under the condition that the values D and C are not changed, (when the product is 11 inches, the value a is 0.45+0.25+0.3 ═ 1.0mm), the value a and the value B also become larger as the product becomes larger, and the cost of the product becomes more expensive as the product becomes larger.
As shown in fig. 4, the wall thickness C of the adhesive frame on the backlight ceiling side is 0.45mm at the minimum, the gap B between the LGP (light guide plate) and the adhesive frame increases with the increase of the product (especially the long edge light entering product), currently, the gap D between the film and the adhesive frame is 0.3mm at the minimum, the value B is 0.20mm, the distance a between the backlight outline and the v.a area is a distance a, and the value E of the light-shielding adhesive film is 0.3mm at the minimum, so that the value a is 0.45+0.3+ 1.05mm when the values of E and C are not changed (when the product is 11 inches).
To sum up, after the frame structure is glued in the cancellation, the utility model discloses a design can unilateral reduce backlight unit size 0.1 ~ 0.15mm, advances the size of little product, satisfies the product and can obtain bigger visual effect in the space of minimum.
