The directions of two inwalls 1112 tilts 1 degree of γ, meanwhile, the second inwall close to the outer surface 1141 of encapsulation cover plate one end in first
Wall tilts 2 degree of γ, and the lighting angle of the first luminescence unit is F2, the wall of the first inwall 1111 and the outer surface of encapsulation cover plate
1141 have the first angle α 1, and the wall of the second inwall 1112 and the outer surface 1141 of encapsulation cover plate have the second angle α 2, its
In, as ∠ γ 1<∠ θ or ∠ γ 2>During ∠ θ, the first inwall 1111 or the second shelter wall 1112 may block luminescence chip side
The some light that edge is sent；As ∠ γ 1=∠ γ 2=∠ θ, the light that luminescence chip edge is sent is exactly along the first inwall
1111 and second inwall 1112 launch；In order to ensure that the first inwall and the second inwall do not block the part that luminescence chip edge is sent
Light is, it is necessary to set ∠ 1 >=∠ of γ θ, ∠ 2≤∠ of γ θ, it is preferred that ∠ γ 1=∠ γ 2=∠ θ；So ∠ 2≤∠ of γ γ 1
=∠ θ.
As shown in figure 11, from exterior angle theorem:∠ α 2=∠ α+∠ γ 2；∠ α=∠ α 1+ ∠ γ 1, so, ∠ α 2-
The ∠ γ 1=2 ∠ θ of ∠ α 1=∠ α+∠ γ 2- (∠ α-∠ γ 1)=∠ γ 2+ ∠ γ 1≤2, i.e., in the first luminescence unit, the

Load plane tilted to unfilled corner 204, then the first luminescence unit 11A lighting angle to the direction of unfilled corner 204 tilt, increase scarce
The light irradiation area in the direction of angle 204, solves the problems, such as light guide plate unfilled corner direction corner shadow in backlight module, display panel it is aobvious
Show that region AA display effects are good, be conducive to making narrow lower frame BA display panel.While the cap of the first luminescence unit
The outer surface of plate and the end face of light guide plate be arranged in parallel, it can be ensured that the first luminescence unit and the close relative structure of light guide plate
Set, reduce light leak, improve the light utilization of the first luminescence unit.
The embodiment of the present invention also provides a kind of display panel, including above-mentioned sidelight type backlight module, and Figure 14 is real for the present invention
The display panel schematic diagram of example offer is applied, display panel as shown in figure 14 includes viewing area AA and rim area BA.The embodiment is carried
In the display panel of confession, the light source of sidelight type backlight module, including load plane and the first direction of chip bearing member have and inclined
First luminescence unit of oblique angle so that the luminous overturning angle of the first luminescence unit, increases the light irradiation area of light source, solves
Certainly display panel lower frame or so corner shadow problem, lifts the display effect of display panel, the display surface that the embodiment is provided
Plate has the characteristics of lower frame is narrow.
By above-described embodiment, sidelight type backlight module of the invention and its light source and display panel, reached as
Under beneficial effect：
In the light source for the light-metering formula backlight module that the present invention is provided, multiple luminescence units are set, it is luminous including first
Unit, load plane and the first direction of the chip bearing member of the first luminescence unit have slanted angle so that first is luminous single
The lighting angle of member is tilted, and increases the light irradiation area of light source, and can reduce light leak with light guide plate close fit simultaneously
Occur, improve light utilization, the backlight module that light guide plate sets left and right unfilled corner can be applied to, solve display panel viewing area
Lower frame or so corner shadow problem, without the two ends of the incident side of light guide plate are done into oblique angle design, it is possible to decrease light guide plate is produced
With optical effect intractability, the narrow design of display panel lower frame can be applied to.
Although some specific embodiments of the present invention are described in detail by example, the skill of this area
Art personnel are it should be understood that example above is merely to illustrate, the scope being not intended to be limiting of the invention.The skill of this area
Art personnel to above example it should be understood that can modify without departing from the scope and spirit of the present invention.This hair
Bright scope is defined by the following claims.
