Specific embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to Convenient for description, part relevant to invention is illustrated only in attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Referring to FIG. 1, the present embodiment provides a kind of backlight module, including flexible circuit board 1 and setting are in the flexible electrical The inverse edge eyeglass 2 of 1 top of road plate,
The flexible circuit board 1 is equipped with the inclined surface 11, Mei Gesuo being sequentially arranged close to the one side of the inverse edge eyeglass 2 It states and light emitting diode 4 is installed on inclined surface 11.
By the way that inclined surface is arranged on flexible circuit board in the present embodiment, and being arranged on inclined surface is miniature shine Diode, it is mini led that this is micro-led, is generally light emitting diode of the size at 100 microns or more, this is micro- The light that type light emitting diode issues passes through the inverse edge eyeglass that is arranged above and carries out narrowed, and the dotted line in Fig. 1 is light schematic diagram, So that the light of the micro-led sending under the driving of same electric current has been narrowed in smaller angle, one side light source Backlight is more bright, on the other hand reduces the power consumption of the area source.
Further, 4 emergent light of light emitting diode extends outwardly along the inclined surface 11.
As shown in Fig. 2, the light that the light emitting diode projects is faced out along inclination, light gets to reversed prism on piece, the hair Optical diode transmitting light is reflected by the upper prism of inverse edge eyeglass, the light of the light emitting diode is carried out it is narrowed, As shown, light can be narrowed effectively after reversed prism.
Further, each inverse edge eyeglass 2 includes multiple prisms, and the inclined surface length direction prolongs with the prism It is identical to stretch direction.
Carry out to guarantee inverse edge eyeglass to the emergent light of light emitting diode it is narrowed, need by the length direction of inclined surface with The extending direction of prism is identical, and emergent light can be reflected by prism, and light carries out narrowed.
Further, each 11 tilt angle of the inclined surface is identical.In the present embodiment in order to guarantee flexible panel prepare And light emitting diode emergent ray is neat, and the angle of inclined surface is arranged to the light identical, multiple light emitting diodes project Line is parallel, and it is more preferable that effect is narrowed after inverse edge eyeglass.
Further, angle is 67 ° -77 ° between 4 emergent light of light emitting diode and 1 normal of the flexible circuit board.
Inclined surface is set on flexible circuit board in the present embodiment, places light emitting diode on inclined surface, in order to guarantee pair The light of light emitting diode transmitting carries out narrowed, and emergent ray setting and the discovery angular range of flexible circuit board be 67 °- 77 °, this light emitting angle can be carried out with reversed prism in the light that vertical direction issues light emitting diode it is narrowed so that area source Backlight is more bright.
Further, angle is 72 ° between the light emitting diode emergent light and the flexible circuit board normal.Above-mentioned angle To be preferable to provide be 72 ° to degree, the setting of above-mentioned angle and narrowing by reversed prism so that backlight illumination about promoted 50% with On, therefore, the power consumption of area source is 65% or so of common area source power consumption under same brightness, while being able to ascend brightness Substantially reduce power consumption.
It further, further include prismatic lens 3, the prismatic lens 3 are arranged above the inverse edge eyeglass 22.
Prismatic lens are set in the top of inverse edge eyeglass in the present embodiment, light are carried out by the prismatic lens lateral into one Step narrows, and is promoted and brightness and further decreases power consumption, and the prismatic lens are smaller to the narrowed effect of light, can it is small-scale into The promotion of row light narrowed with brightness, more optimizes the performance of backlight module in the present embodiment.
Further, the prismatic lens 3 are vertically arranged with the inverse edge eyeglass 2.In order to enable increased prismatic lens are to hair The light of optical diode is further narrowed, and is vertically arranged prismatic lens and inverse edge eyeglass in the present embodiment, can be into one Walk raise-intensity.
