The utility model provides a backlight module.
In the embodiment of the present invention, as shown in fig. 1 and 2, the backlight module includes a light guide plate 100, an optical film 200, and a buffer 300; the light guide plate 100 has a light emitting portion 110, and at least two opposite sides of the light emitting portion 110 are provided with bosses 120; the optical film 200 is disposed on the light emergent portion 110 and between the two bosses 120; the buffer 300 is disposed on the boss 120. The buffer 300 of the embodiment of the present invention is used to support the display panel 600.
The light guide plate 100 mainly functions to convert a linear light source of a light source into a planar light source, and the planar light source is emitted from the light emitting portion 110, the light emitting portion 110 has a light emitting surface, and actually, the light source is a planar light source emitted from the light emitting surface, so that light irradiated onto the display panel 600 is more uniform, therefore, the optical film 200 is located at the side of the light emitting portion 110, the protrusion 120 is disposed on the light emitting portion 110, and the optical film 200 is disposed between the two protrusions 120, so that the protrusion 120 supports the display panel 600. Because display panel 600's intensity is not high, so set up bolster 300 on boss 120 with direct and display panel 600 contact, play the cushioning effect to realized need not gluing the frame and support, directly supporting display panel 600's function with light guide plate 100, reached the effect that reduces backlight unit's thickness, and then reached the effect that reduces display device thickness.
The at least two bosses 120 are disposed on at least two opposite sides of the light-emitting portion 110, which means that the at least two bosses 120 respectively support the display panel 600, so that the support between the display panel 600 and the backlight module is more balanced.
The utility model discloses technical scheme is through setting up two relative bosss 120 on light-emitting portion 110 at light guide plate 100, and optics diaphragm 200 sets up between two bosss 120, and is equipped with bolster 300 on boss 120 and supports display panel 600 with direct, has realized need not to glue the function that the frame just can support, has reached the effect that reduces backlight unit and display device thickness.
Further, as shown in fig. 1, the boss 120 is provided with a groove 121, and the buffer member 300 is located in the groove 121. The buffer member 300 is disposed in the groove 121, so that the installation of the buffer member 300 is more stable.
In an embodiment of the present invention, the height of the buffer member 300 is greater than or equal to the depth of the groove 121. The height of the buffer member 300 is greater than or equal to the depth of the groove 121, so that the buffer member 300 protrudes out of the mesa of the boss 120, and thus the buffer member 300 can directly contact with the display panel 600, and the display panel 600 is prevented from directly contacting with the boss 120 to cause abrasion.
In practical application, the specific material of the buffer member 300 may be determined according to practical situations, as long as it has certain flexibility or plasticity, such as rubber, silicone, plastic, etc. In an embodiment of the present invention, it is preferable that the buffer member 300 is a rubber strip in consideration of the cost and the processing technology.
Further, as shown in fig. 1, the height of the boss 120 is greater than the thickness of the optical film sheet 200. The height of the boss 120 is greater than the thickness of the optical film 200, which means that the mesa of the boss 120 protrudes out of the optical film 200, so that the boss 120 does not press the optical film 200 when supporting the display panel 600, thereby preventing the optical film 200 from wrinkling and improving the quality of the display image.
In an embodiment of the present invention, as shown in fig. 1 and fig. 2, the light-emitting portion 110 includes two sets of sides 130 disposed oppositely, two bosses 120 are respectively disposed on two opposite sides 130, and each boss 120 extends from one side 130 to the other opposite side 130. At this time, the two bosses 120 are respectively disposed on the two opposite side edges 130 of the light-emitting portion 110, and each boss 120 is continuously disposed on the side edge 130, so that the contact surface between the boss 120 and the display panel 600 is wider, and the supporting effect is more stable.
In an embodiment of the present invention, the bosses 120 are disposed on the periphery of the light emitting portion 110, and the four bosses 120 are disposed around the optical film 200. At this time, the bosses 120 are disposed around the light emitting part 110, and the supporting force of the bosses 120 to the display panel 600 is more balanced.
In addition to the above two embodiments, in consideration of the ease of the processing, it is preferable to provide the bosses 120 on the opposite sides of the light emitting portion 110.
Further, the specific structure of the boss 120 may be determined according to actual conditions, and in the embodiment of the present application, it is preferable that the boss 120 is manufactured in an integrated manner with the light guide plate 100, so that the manufacturing process is more convenient and more stable.
Further, as shown in fig. 1 and 2, the backlight module further includes a reflective sheet 400, and the reflective sheet 400 is disposed on a bottom surface of the light guide plate 100 opposite to the light emergent portion 110. The main function of the reflective sheet 400 is to prevent light from leaking from the bottom surface of the light guide plate 100, and to reflect light irradiated onto the bottom surface into the light guide plate 100 to be emitted from the light emitting part 110. The reflective sheet 400 may be made of aluminum, which has a high reflectivity.
In an embodiment of the present invention, the backlight module further includes a backlight source (not shown), the light guide plate 100 has an incident light side (not shown) adjacent to the light emitting portion 110, and the backlight source is disposed corresponding to the incident light side. The backlight source is preferably an LED lamp. The backlight irradiates light into the light guide plate 100 from the light incident side, and irradiates the light through the light emergent portion 110 after being reflected and refracted, so as to irradiate the display panel 600.
It is understood that, in the specific application process of the two embodiments, either one of the two embodiments can be implemented alone, or both of the two embodiments can be implemented together, that is, the following three cases are included: the case where the reflection sheet 400 is provided alone, the case where the backlight is provided alone, or the case where both the backlight and the reflection sheet 400 are provided may be employed.
