Description
Technical field
The present invention relates to light guide plate technical fields, and in particular to a kind of light guide plate of hole structure.
Background technology
With the continuous variation of smart mobile phone shape, to obtain the vision area range of bigger, mobile phone screen continues to increase in one's hands
Machine edge placement.Since preposition pick-up lens structure limits, cell phone back light source before this all shortens length to avoid camera position
It sets.
And it is unfavorable for the full frame effect of mobile phone by shortening backlight length, therefore study by backlight corresponding position
One trepanning is set to place camera, then mobile phone display screen can be lengthened to mobile phone edge, be designed to ultra-narrow frame or Rimless
Mobile phone, and then light guide plate also needs to do corresponding trepanning setting.Meanwhile trepanning is carried out in light guide plate, due to guide-lighting plate injection moulding
When can be formed at this aperture perimeters melt run and molecule flowing inconsistent influence light conduction, therefore in optical visual effect
On be not easy to meet the requirements, it is also necessary to carry out optical arrangement processing.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of light guide plate of hole structure.This is with holes
The light guide plate of structure can be effectively increased the screen accounting of mobile phone display screen, while the uniformity of light emission luminance is unaffected.
The purpose of the present invention is achieved through the following technical solutions.
A kind of light guide plate of hole structure, including light conducting plate body and light guiding points；The bottom end of the light conducting plate body is
Light source incidence orientation；The light guiding points are the light reflection micro-structure being distributed in light conducting plate body；The top of the light conducting plate body
Portion offers a through-hole.
Preferably, the through-hole is inside light conducting plate body and close to edge.
Preferably, the position of the through-hole is positioned at the top both sides for including light conducting plate body, or is located at light conducting plate body
Top centre position.
The production of the light guide plate of the hole structure can produce in existing injection molding production equipment, be not necessary to change production stream
Journey is not necessary to post-processing processing, can meet mass production.
Preferably, the through-hole includes circular through hole.
Preferably, the light guide plate of a kind of hole structure described in any one of the above embodiments, it is guide-lighting in the light source offside of the through-hole
That puts is densely distributed.
It is furthermore preferred that a kind of light guide plate of hole structure described in any one of the above embodiments is led in the light source offside of the through-hole
The distribution density of luminous point is more than the distribution density of light guiding points any other position in light conducting plate body.
The light guide plate of the hole structure of the present invention, since position of opening generates barrier to light conduction in light guide plate,
It needs to be adjusted the light guiding points regularity of distribution near position of opening, improves the guide-lighting dot density of trepanning light source offside, to
The Integral luminous brightness uniformity for making light guide plate makes tapping illumination effect and the illumination effect of whole light guide plate be consistent.
Compared with prior art, the invention has the advantages that and advantageous effect：
The light guide plate of the hole structure of the present invention can make mobile phone display screen break through the limitation of preceding camera, and mobile phone display screen is made to reach
Ultra-narrow frame or Rimless；Meanwhile by being adjusted to the light guiding points regularity of distribution near position of opening, improving trepanning light
The guide-lighting dot density of source offside makes tapping illumination effect and whole leaded light to make the Integral luminous brightness uniformity of light guide plate
The illumination effect of plate is consistent.
Description of the drawings
Fig. 1 is the structural schematic diagram of the light guide plate of hole structure of the invention in specific embodiment；
Fig. 2 is the partial side schematic diagram of the light guide plate of hole structure of the invention in specific embodiment；
Fig. 3 is the close-up schematic view at A in Fig. 1.
Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with specific embodiment and attached drawing, but the present invention
Protection domain and embodiment it is without being limited thereto.
Embodiment 1
A kind of light guide plate of hole structure, the structural schematic diagram of the light guide plate of the hole structure of the present embodiment is as shown in Figure 1, include
Light conducting plate body 1 and light guiding points 2；The material of light conducting plate body 1 is iron, in the backlight with the light guide plate, bottom end
For light source incidence orientation, correspond to light source installation position 4, light source installation position 4 is equipped with LED light strip 5 and is used as illuminating source；Light guiding points
2 be the light reflection micro-structure being distributed in light conducting plate body 1；The top of light conducting plate body 1 offers a through-hole close to edge
3；
Wherein, as shown in Fig. 2, through-hole 3 is circular through hole, the position of through-hole 3 is located at the top left hand of light conducting plate body 1 by near side (ns)
At edge.
By open-celled structure, so that light guide plate is can adapt to the requirement of the high accounting of mobile phone display screen, mobile phone display screen is made to break through
The limitation of preceding camera makes mobile phone display screen reach ultra-narrow frame or Rimless；
Embodiment 2
A kind of light guide plate of hole structure, as shown in figure 3, in the light source offside of through-hole 3, light guiding points 2 are densely distributed, specially：
The distribution density of light guiding points 2 is more than the distribution density of any other position in light conducting plate body 1 of light guiding points 2.
The present embodiment adjusts the distribution situation of light guiding points in the adjacent edges of the hole structure of light guide plate, attached to position of opening
The close light guiding points regularity of distribution is adjusted, and improves the guide-lighting dot density of trepanning light source offside, to make the entirety of light guide plate
Light emission luminance is uniform, and tapping illumination effect and the illumination effect of whole light guide plate is made to be consistent, aobvious can adapt to mobile phone
The requirement of the high accounting of display screen, it is non-uniform to solve the problems, such as that trepanning is easy to cause light emission luminance.
Above example is only the preferred embodiment of the present invention, is only that further detailed to technical scheme of the present invention work
Description, but do not limit the scope of the invention, any change done without departing from spirit of the invention, combination, deletion,
Replacement or modification etc. are included in protection scope of the present invention.
