Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
As shown in fig. 1 and 2, the light leakage prevention backlight module provided by the present utility model includes:
a frame 10 for fixing the backlight module, wherein the inner wall of the frame 10 is covered with a light absorbing film 20; a light guide plate 30 disposed within the frame 10; an optical film 40 covering at least a partial area of the light guide plate 30; a backlight 50 disposed at the bottom of the light guide plate 30; a backlight flexible circuit board 60 disposed at the bottom of the optical film 40, and the backlight 50 is disposed on the backlight flexible circuit board 60; a reflective film 70 covering at least a partial region of the optical film 40; a light shielding adhesive layer 80 covering the reflective film 70.
According to the utility model, the light absorption film 20 is covered on the inner wall of the frame 10 of the backlight module, so that light leakage at the edge of the backlight module can be absorbed, the light leakage of the display module is avoided, the brightness provided by the backlight module is increased, the visual effect is enhanced, and the experience of a user is improved.
The optical film 40 includes a diffusion sheet 41, a first prism sheet 42, and a second prism sheet 43, which are stacked.
In this embodiment, the backlight 40 preferably includes LEDs, which are low cost, high brightness, and long service life, and are common materials for backlights.
In this embodiment, the light absorbing film 20 is preferably disposed corresponding to the backlight 50. If the light emitted from the backlight 50 is not guided in the correct direction by the light guide plate 30 or the reflective film 70 does not reflect the light to the direction of the display panel, the light is likely to leak out from the edge of the backlight module, and thus the light absorbing film 20 is disposed corresponding to the backlight 50, and the leaked light can be absorbed better due to the position of the corresponding light source.
The light absorbing film 20 is a black film layer.
Example 2
The utility model provides a display module, which comprises a light leakage prevention backlight module in an embodiment 1. A display panel is also included.
The display panel and the light leakage prevention backlight module are adhered and fixed through the light shielding glue layer 70. Although the light shielding layer 70 also has a light shielding effect, the light shielding effect on the edge of the backlight module is somewhat insufficient due to the direction, so that the light absorbing film 20 needs to be added to absorb the light leaking from the edge of the light module, so as to avoid light leakage.
The bottom binding flexible circuit board of the display panel is electrically connected with the backlight flexible circuit board 50. Since the backlight flexible circuit board 50 itself has no separate power source, it needs to be connected to the flexible circuit board, relying on the flexible circuit board to supply power.
Example 3
The utility model also provides electronic equipment, which comprises the light leakage prevention backlight module in the embodiment 1 and/or the display module in the embodiment 2. Because the light absorption film 20 is covered on the inner wall of the frame 10 of the backlight module, light leakage at the edge of the backlight module can be absorbed, the light leakage of the display module is avoided, the brightness provided by the backlight module is increased, and the visual effect is enhanced.
According to the utility model, the light absorption film is covered on the inner wall of the frame of the backlight module, so that light leakage at the edge of the backlight module can be absorbed, the light leakage of the display module is avoided, the available brightness of the backlight module is increased, the visual effect is enhanced, and the experience of a user is improved.
The embodiments of the present utility model have been described above with reference to the accompanying drawings, but the present utility model is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present utility model and the scope of the claims, which are to be protected by the present utility model.
