Description
Technical Field
The present disclosure relates to the field of electronic devices, and in particular, to a backlight module and a terminal device.
Background
With the development of science and technology, Light Emitting Diode (LED) backlight modules have been gradually replaced by side-in type backlight modules, and as people demand higher and higher module designs, the thickness of the side-in type backlight modules is thinner and thinner, so that more and more problems are generated, wherein edge Light leakage becomes a problem that is difficult to completely improve in optics.
In the related art, the light intensity is generally reduced by shielding with a frame or blacking the edge of the film to solve the problem of light leakage at the edge.
Disclosure of Invention
In order to overcome the problems in the related art, the present disclosure provides a backlight module and a terminal device to solve the problem of edge light leakage.
According to a first aspect of the embodiments of the present disclosure, there is provided a backlight module, including: a light source and a light guide plate LGP; wherein,
the light source is arranged on the side edge of the LGP;
the side edge of the light-emitting surface of the LGP is provided with an opaque shading area.
Because the light source is arranged on the side edge of the LGP, and the side edge of the light-emitting surface of the LGP is provided with the opaque shading area, the opaque shading area can reflect the light leakage at the edge of the backlight module into the LGP, so that the waste of light energy can be reduced, and the utilization rate of the light energy is improved.
In one possible design, the backlight module further includes a light shielding patch, and the light shielding patch is disposed at a side edge of the light emitting surface of the LGP to form the opaque light shielding region.
In one possible design, a side edge of the light-emitting surface of the LGP to which the light-shielding sticker is attached is a mirror surface.
Because the shading paste is arranged at the side edge of the light-emitting surface of the LGP of the backlight module, and the side edge of the light-emitting surface of the LGP pasted with the shading paste is a mirror surface, the mirror surface can well return the light leakage at the edge to the interior of the LGP so as to reuse the light leakage, thereby improving the utilization rate of light.
In one possible design, the light blocking sticker is attached to a side edge of the light emitting surface of the LGP by an adhesive.
Because the shading paste is pasted on the side edge of the light-emitting surface of the LGP through the adhesive, the firmness of the shading paste on the LGP can be improved.
In one possible design, the width of the shading paste ranges from 1mm to 3mm, and the thickness of the shading paste ranges from 0.5 mm to 2 mm.
By selecting the proper width and thickness of the shading paste, the color light phenomenon caused by poor bonding of the LGP edge glass can be improved.
In one possible design, the backlight module further includes ink applied to a side edge of the light-emitting surface of the LGP to form the opaque light-shielding area.
Since the ink is coated on the side edge of the light emitting surface of the LGP to reflect the light leakage at the edge back to the inside of the LGP to reuse the light leakage, the utilization rate of the light energy can be improved.
According to a second aspect of the embodiments of the present disclosure, there is provided a terminal device, including a housing and a display screen, wherein the housing has a screen gap, and the display screen is disposed in the screen gap; the display screen comprises the backlight module.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects:
because the light source is arranged on the side edge of the LGP, and the side edge of the light-emitting surface of the LGP is provided with the opaque shading area, the opaque shading area can reflect the light leakage at the edge of the backlight module into the LGP, so that the waste of light energy can be reduced, and the utilization rate of the light energy is improved.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.
