Many details are explained in the following description in order to fully understand herein, still, can also be adopted herein
Implemented with other than the one described here mode, therefore, the protection scope of this paper is not by following public specific implementation
The limitation of example.
Backlight module provided by the invention, as shown in Figures 1 to 8, comprising: light guide plate 1, front is light-emitting surface, in institute
The back side opposite with the light-emitting surface for stating light guide plate is provided with holding tank 11；With the backlight lamp bar 2 with lamp bead 22, it is set to
The back side of light guide plate 1, lamp bead 22 are sunk in holding tank 11, and lamp bead 22 is configured to shine to the side wall of holding tank 11 and illuminate leaded light
The inside of plate 1.
The backlight module, backlight lamp bar 2 are set to the back side of light guide plate 1, and lamp bead 22 sinks to the holding tank at 1 back side of light guide plate
The inside of light guide plate 1 is shone and illuminated in 11 and to the side wall of holding tank 11, this structure is when being applied to display equipment, glue frame
Frame only need to engage membrane material, it is no longer necessary to stretch out membrane material a part to prevent lamp bar side leakage light, show equipment in this way
The thickness of frame can make narrower, can be realized ultra-narrow frame design truly.Backlight lamp bar is moved from end
To the back side, border width can also be made narrower, and screen design comprehensively can be better achieved.
Wherein, as shown in figure 4, backlight lamp bar 2 includes: the substrate 21 for the strip being vertically arranged, it is set to light guide plate 1
The back side；With lamp bead 22, it is set to the front of substrate 21, the front of substrate 21 is the surface at 1 back side of Korea's light guide plate, on light guide plate 1
It is provided with holding tank 11, lamp bead 22 is sunk in holding tank 11, and the light that more conducively lamp bead 22 emits all is injected in light guide plate 1.
Such as: backlight lamp bar 2 can select LED light bar, and lamp bead 22 can be set to lateral emitting.
Backlight lamp bar 2 can be set one, be also possible to spaced multiple, and the quantity of holding tank 11 can be and lamp
The quantity of pearl 22 is set as identical, and lamp bead 22 is set as corresponding and sink in holding tank 11, and substrate 21 is pasted in light guide plate 1
On the back side.Substrate 21 and light guide plate 1 are stripe board.Long side of the broadside of substrate 21 towards light guide plate 1, the long side court of substrate 21
To the broadside of light guide plate 1.
Preferably, as shown in figure 4, lamp bead 22 is including multiple, multiple lamp beads 22 can be (right on the length direction of substrate 21
Should be in the width direction of light guide plate 1) it is staggered into two rows of (that is: two rows of lamp bead mutual dislocations), it is right between such lamp bead 22
Blocking for light is less, so that light preferably exposes to any position in light guide plate 1, multiple lamp beads 22 can also be in substrate
In a row or three rows etc. are set on 21 length direction, the purpose of the application can be achieved, objective is set without departing from of the invention
Thought is counted, details are not described herein, in the protection scope that should belong to the application.
Optionally, as shown in Figure 6 to 8, lamp bead 22 can be set to lateral emitting, the light-emitting surface phase of two rows of lamp beads 22
To and interlaced with each other open.
Two rows of intervals of lamp bead 22 put, shine in opposite directions, and every 22 light emitting angle of lamp bead is two rows of for being set as 120 degree
The light that lamp bead 22 emits can cover all areas in light guide plate 1, and more uniformly be radiated at any position in light guide plate 1, lead
Without any dark Angle Position in tabula rasa 1, so that picture each position be made to shine more evenly.If adjacent two lamp bead 22 on a bank light pearl 22
Spacing is A, then adjacent on optimal distance and another bank light pearl 22 that can calculate between two rows of lamp beads 22 by calculating
Optimal distance and position between two lamp beads 22 preferably avoid generating dark space in light guide plate 1.
It is also possible to multiple lamp beads 22 to offset one from another on the extending direction of holding tank 11, the back side of light guide plate is provided with
Two holding tanks 11 sink to a bank light pearl 22 in each holding tank 11, and the lamp bead 22 in two holding tanks, which can offset one from another, to be set
It sets, can also realize the purpose of the application, objective is without departing from design philosophy of the invention, and details are not described herein, also should belong to this
In the protection scope of application.
Optionally, as shown in figure 3, the back side of light guide plate 1 includes: mounting surface 12, holding tank 11 is set on mounting surface 12,
Backlight lamp bar 2 is set on mounting surface 12 along the width direction of light guide plate 1；With two transition faces 13, in the length side of light guide plate 1
It is located at the both sides of mounting surface 12 upwards, and one end of the separate mounting surface 12 of two transition faces 13 is towards the light-emitting surface of light guide plate 1
Both ends inclination extend, so that the thickness at the middle part of light guide plate 1 is greater than thickness (the i.e. thickness of light guide plate 1 at its length direction both ends
It spends self installation face 12 to reduce to the both ends of the separate mounting surface 12 of transition face 13).The both ends of 1 length direction of light guide plate are apart from backlight
Lamp bar 2 is shorter apart from remote but ray traveling optical paths, the ray density of outgoing increases, and compensates the problem of both ends brightness reduces with this, this
The brightness at sample both ends can be set to reach almost the same with middle part brightness, and the entire picture for showing equipment is made to shine more evenly；
The thickness at the structure backlight module length direction both ends is narrower, can reduce 2mm thickness or so.Mounting surface 12 is plane, transition
Face 13 is plane or curved surface.
I.e. backlight lamp bar 2 is set in 1 back side of light guide plate by the light guide plate 1 setting stepped cross as shown in Fig. 2 to Fig. 8
Portion is arranged two rows of lamp beads 22 by interval and shines in opposite directions, can improve the guide-lighting performance of light guide plate 1, one bank light pearl 22 of left side is penetrated
Towards projecting on the right side of light guide plate 1, the light that one bank light pearl 22 of right side is projected projects light out towards the left side of light guide plate 1, and two
Bank light pearl 22 illuminates intermediate part jointly, and the both ends of the length direction of light guide plate 1 are apart from lamp bead 22 apart from remote but ray traveling optical paths
Shorter, the ray density of outgoing increases, and the problem of both ends brightness reduces is compensated with this, thus each position in uniform light guide plate 1
Brightness, also eliminate the incident side leakage problem of traditional side entrance back lamp bar 2, can be better achieved display equipment it is narrow
Frame design and comprehensively screen design.
Preferably, as shown in Fig. 2, Fig. 3, Fig. 6 and Fig. 7, the light-emitting surface of light guide plate 1 is concave curved surface, and radius of curvature is
4200mm can be used for curved-surface display equipment.Backlight module further includes backboard 3 and glue frame etc., and light guide plate 1 is arranged in backboard 3
The notch 31 for accommodating the connecting terminal of backlight lamp bar 2 can be set in back side, the lower end or upper end of backboard 3, wherein backboard 3
Shape and the shape at 1 back side of light guide plate match.The connecting terminal of backlight lamp bar 2 be located at the back side of substrate 21 lower end or on
End.
The side and the back side of light guide plate 1 are coated with reflecting layer (for reflection light), are provided with light shield layer on reflecting layer, are hidden
Photosphere can be shading rubber belt, for preventing light leakage.
