Problems solved by technology

[0004] The optical film 130 of the conventional backlight module 100 is fixed on the frame body 116 by means of two adhesive tapes 140, so the assembly process of the existing backlight module 100 is relatively cumbersome and has many assembly components.
Therefore, the assembly man-hours and assembly costs of the existing backlight module 100 are relatively high.

Abstract

The invention discloses a fixing method for a backlight module and an optical patch; the backlight module comprises a base, a light source, a plurality of fixed components and an optical patch. The light source is arranged on the base and can emit light. Each fixed component has a pair of flexible connectors arranged on the base and a pair of clipping fasteners which are respectively arranged on the flexible connectors. The flexible connectors of each fixed component maintain the gaps, and the flexible connectors of each fixed component can make flexible deformation by narrowing the gaps. The optical patch is arranged on the base and has a plurality of fixed holes. The light passes through the optical patch. The flexible connectors of each fixed component pass through one of the fixed holes; each fixed hole is limited between each clipping fastener of the corresponding fixed component and the base, so that the optical patch is restricted in moving on a first axis, a second axis and a third axis; the first axis, the second axis and the third axis are perpendicular to each other.

Description

technical field [0001] The present invention relates to a fixing method of a backlight module (backlight module) and an optical film (optical film), and in particular relates to a backlight module with a fixing module (fixing module) and using the fixing module to fix the optical film fixed method. Background technique [0002] FIG. 1 is a partially exploded schematic view of a conventional backlight module. The conventional backlight module 100 includes a base 110 , a light source 120 and an optical film 130 . The light source 120 includes a plurality of light-emitting diode devices (LED devices) 122 and a circuit board 124 . And the LED devices 122 are electrically connected to the circuit board 124 . [0003] The base 110 includes a back bezel 112 , a light-guiding plate (LGP) 114 and a frame 116 disposed on the base 112 . The light guide plate 114 is disposed on the base 112 , and the light source 120 is disposed on the base 112 and located beside the light guide pla...
