Highly shock-resistant and wear-resistant backlight module

Abstract

A highly shock-resistant and wear-resistant backlight module includes a backplate, a light-emitting component, a reflective film, a plurality of elastic buffers, a light guide plate, a plurality of optical films, and a top frame. The plurality of elastic buffers are respectively disposed on the inner bottom surface of the backplate and abut against the inner side surface of the backplate. Each elastic buffer has a groove. The light guide plate is disposed on the plurality of elastic buffers and has a plurality of corner portions, which are respectively disposed in the grooves of the plurality of elastic buffers. The light guide plate is supported by the plurality of elastic buffers, and the plurality of elastic buffers can absorb vibration or impact force, which can prevent the light guide plate from breaking due to vibration or external impact, or prevent the light guide plate from slipping and scratching other optical films.

Claims

1. A backlight module with high shock resistance and wear resistance, comprising: a back plate having an inner bottom surface and an inner side surface to form an accommodating space; a light-emitting component disposed on the inner side surface of the back plate; a reflective film disposed on the inner bottom surface of the back plate; a plurality of elastic buffers disposed on the inner bottom surface of the back plate and abutting against the inner side surface, each elastic buffer having a groove; a light guide plate disposed on the plurality of elastic buffers and corresponding to the position of the light-emitting component, wherein the light guide plate has a plurality of corner portions, the plurality of corner portions being respectively disposed in the grooves of the plurality of elastic buffers; a plurality of optical films stacked on the light guide plate; and an upper frame disposed on the back plate.

2. The backlight module with high shock resistance and wear resistance as described in claim 1, wherein, The light guide plate has a plurality of protrusions around its periphery, and the ends of the plurality of protrusions abut against the inner side surface of the back plate.

3. The backlight module with high shock resistance and wear resistance as described in claim 2, wherein, The width of each convex part gradually decreases outward.

4. The backlight module with high shock resistance and wear resistance as described in claim 1, wherein, The shape and size of the groove of each elastic buffer element correspond to the shape and size of each corner of the light guide plate.

5. The backlight module with high shock resistance and wear resistance as described in claim 1, wherein, At least one of the multiple elastic buffers has a right-angled groove.

6. The backlight module with high shock resistance and wear resistance as described in claim 1, wherein, At least one of the plurality of elastic buffers has a groove comprising a right-angled groove and a circular groove connecting the corner of the right-angled groove.

7. The backlight module with high shock resistance and abrasion resistance as described in claim 1, wherein, At least one of the plurality of elastic buffers has a groove comprising a right-angled groove and a side groove connecting the corner of the right-angled groove.

8. The backlight module with high shock resistance and abrasion resistance as described in claim 1, wherein, At least one of the plurality of elastic buffers has a groove comprising a right-angled groove and a polygonal groove connecting the corner of the right-angled groove.

9. The backlight module with high shock resistance and wear resistance as described in claim 8, wherein, The polygonal slot includes a chamfered edge.

10. The highly shock-resistant and wear-resistant backlight module as described in claim 8, wherein, The inner surface of the polygonal groove has multiple arc-shaped protrusions to form a wave-like structure.
