Benefits of technology

The present invention replaces the material removing design with a bent striped sheet back cover for holding backlight components in a backlight module. This method avoids the need for additional material removal, reducing waste and lowering material costs.

Problems solved by technology

However, the said material removing method may cause unnecessary waste of material, so as to increase the material cost of the backlight module 10 in manufacturing the back cover 20.

Embodiment Construction

[0019]Please refer to FIG. 3, which is an exploded diagram of a backlight module 100 according to an embodiment of the present invention. As shown in FIG. 3, the backlight module 100 includes a plurality of light emitting units 102, a plurality of optical films 104, a plastic frame 106, a light guide plate 108, and a back cover 110. The plurality of light emitting units 102 is disposed at a side of the light guide plate 108 for emitting light to be incident into the light guide plate 108. The light emitting unit 102 is preferably an LED (Light Emitting Diode). The plurality of optical films 104 (e.g. a lens film and a diffuser film) is disposed on the plastic frame 106 disposed on the light guide plate 108, so that light emitted from the light guide plate 108 can be transformed into a planar light source with sufficient brightness and uniform distribution via the optical films 104. The light guide plate 108 is disposed on the back cover 110. Via the aforesaid disposition, the back c...

Abstract

A back cover manufacturing method includes providing a striped sheet, bending the striped sheet along a long side of the striped sheet to form a hem, cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming a plurality of striped sections, and bending the plurality of striped sections to form a back cover. The back cover is used for being disposed in a backlight module to hold at least one optical component of the backlight module.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a back cover manufacturing method, and more specifically, to a back cover manufacturing method by bending a striped sheet to form a back cover.[0003]2. Description of the Prior Art[0004]In general, a conventional backlight module has a back cover and disposal of the back cover is as shown in FIG. 1, which is an exploded diagram of a backlight module 10 according to the prior art. As shown in FIG. 1, the backlight module 10 includes a plurality of light emitting units 12, a plurality of optical films 14, a plastic frame 16, a light guide plate 18, and a back cover 20. The plurality of light emitting units 12 is disposed at a side of the light guide plate 18 as a backlight source. The plurality of optical films 14 is disposed on the plastic frame 16 to make light emitted from the light guide plate 18 transform into a planar light source with sufficient brightness and uniform distribution. ...
