Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides a backlight module for accommodating two cameras, including: the light guide plate comprises a light guide plate 1, an optical diaphragm 2, a frame, a first through hole 3 arranged on the light guide plate 1, the optical diaphragm 2 and the frame, a second through hole 4 arranged on the light guide plate 1, the optical diaphragm 2 and the frame, and shading glue 5, wherein front cameras are respectively arranged in the first through hole 3 and the second through hole 4. The first through hole 3 and the second through hole 4 may be disposed in the middle or at both sides of the light guide plate 1, the optical film 2, and the frame.
Referring to fig. 1 and 2, the first through hole 3 and the second through hole 4 may be disposed horizontally or vertically, the first through hole 3 and the second through hole 4 are disposed adjacently and spaced apart by a certain gap h, and the gap h is greater than 2mm to ensure the brightness between the two through holes. The diameters of the first through hole 3 and the second through hole 4 may be equal, and the sizes of the two through holes may be different in order to appropriately increase the screen occupation ratio. Consider that light source transmission light is obstructed in through-hole department, there is the dark space the through-hole is kept away from the light source side, will reduce the dark space problem of through-hole rear side and improve the screen and account for the ratio, the size of through-hole is the better less, nevertheless considers the size of camera module, needs the size of suitably setting up the through-hole: the diameter range of the first through hole 3 and the second through hole 4 is 2-4 mm.
Referring to fig. 3 and 4, the first through hole 3 and the second through hole 4 may be combined into a runway through hole 31, and the width b of the runway through hole is the same as the diameter of the two through holes, but the length of the runway through hole 31 affects the light processing, and the length c of the runway through hole 31 is required to be less than 8 mm. Especially when the runway through-hole 31 is arranged laterally, its length is preferably 5.5mm, so that the light on the rear side of the through-hole is better treated. When two through holes with different sizes are combined into the special-shaped runway through hole 32 and the special-shaped runway through hole 32 is longitudinally arranged, one end with wider width faces downwards, namely, the end faces to the light source end, and light processing is facilitated.
The first and second through holes 3 and 4 may be circular, oval or rectangular, but circular is better for handling light than other shapes.
Referring to fig. 6, through holes are formed in the positions of the light shielding adhesive 5 corresponding to the first through hole 3 and the second through hole 4, the light shielding adhesive 5 includes a first light shielding adhesive 51 disposed around the optical film 2 and a second light shielding adhesive 52 disposed around the first through hole 3 and the second through hole 4, and the second light shielding adhesive 52 has the same shape as the first through hole 3 and the second through hole 4. The frame comprises an iron frame 6, and in order to prevent light from entering the through hole, the structure at the through hole of the iron frame 6 has the following four conditions.
The first method comprises the following steps: referring to fig. 5 and 6, the iron frame 6 is bent toward the first through hole 3 and the second through hole 4 to form an iron frame annular pillar 7, and the top surface of the iron frame annular pillar 7 is adhered to the second light-shielding adhesive 52 to fix the optical film 2 and shield the inner side of the through hole.
And the second method comprises the following steps: referring to fig. 7, a rubber frame ring-shaped pillar 8 is disposed on the iron frame ring-shaped pillar 7 in the first case, the width of the rubber frame ring-shaped pillar 8 is greater than the width of the iron frame ring-shaped pillar 7, the bottom surface of the rubber frame ring-shaped pillar 7 is attached to the iron frame 6, and the top surface of the rubber frame ring-shaped pillar 8 is attached to the second light-shielding adhesive 52. Compared with the first case, the adhesive area of the second light shielding adhesive 52 can be increased by arranging the adhesive frame ring-shaped support 8, so that the structure is more stable.
And the third is that: referring to fig. 8, the iron frame ring-shaped support 7 is embedded inside the rubber frame ring-shaped support 8, so that the rubber frame ring-shaped support 8 surrounds the iron frame ring-shaped support 7. Compared with the second case, the structure is firmer and can not fall off.
And fourthly: referring to fig. 9, the iron frame ring-shaped support 7 is bent towards the center of the first through hole 3 or the second through hole 4 along the horizontal direction to form a support ring 9, and the top surface of the support ring 9 is adhered to the second light-shielding adhesive 52. The method can increase the bonding area of the iron frame and the shading glue and play a role in reinforcement.
Because of expend with heat and contract with cold reason, there is the phenomenon that the shrink was shifted in light guide plate 1, and light guide plate 1 of light source end is fixed, therefore light guide plate 1 can contract toward the light source end, if light guide plate 1 contracts to can influence the light efficiency in the through-hole, and if touch chase annular pillar 7 and can lead to the light guide plate fracture, influence the quality. Therefore, the first through hole 3 and the second through hole 4 on the light guide plate 1 are irregularly round, and one end of the through hole of the light guide plate 1, which is far away from the light source, is shifted outward, so that a gap a is formed between one end of the first through hole 3 or the second through hole 4 on the light guide plate 1, which is far away from the light source, and the edge of the second light shielding adhesive 52, which is close to the one end, and the gap a gives a space for the light guide plate 1 to shrink, where 0< a. When the light guide plate 1 contracts, the light guide plate 1 does not contract into the second light shielding glue 52 and does not touch the bezel annular pillar 7.
Referring to fig. 2, a double-sided adhesive tape 10 is disposed on a light-emitting surface of one end of the light guide plate 1 close to the light source, the double-sided adhesive tape 10 is adhered to the optical film 0, and the double-sided adhesive tape 10 is also disposed on the light-emitting surface of one end of the light guide plate 1 away from the light source, so as to fix the optical film 2.
To sum up, the utility model discloses set up first through-hole and second through-hole or set up a runway through-hole and hold leading two cameras on backlight unit to in order to prevent that light from penetrating into the through-hole, set up iron frame annular pillar and glue frame annular pillar and shelter from light in through-hole department, guarantee backlight unit's optical effect, also can play fixed optical module's effect simultaneously.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
