Problems solved by technology
During the lift-off process, the glue is deformed by the push of the sheet tool, which indirectly deforms the circuit board attached to it; when the deformation of the circuit board is serious, the light source module will be damaged, or even unable to reuse
In addition, the elastic deformation range of the circuit board of the light source module is not large, so that the above-mentioned lift-off process can easily cause permanent deformation of the circuit board.
When the bent circuit board is reused, stronger adhesion is required to fix it on the support member, and it is accompanied by residual internal stress, which makes the circuit board have the potential risk of peeling off from the support member

The invention discloses a backlight module, comprising a lamp bracket, a light source module and a fixed part. The lamp bracket is provided with a first surface, a second surface with respect to the first surface and a through hole communicated with the first and the second surfaces. A light source module is disposed on the first surface and covers at least a part of the through hole. The fixed part is adhered to the second surface and passes through the through hole to be adhered to the light source module. When the light source module is dismounted, the fixed part can be independently removed without influencing the light source module or other parts. The invention is advantageous in that the light source module can be taken out without damage; the problem of deformation when peeling the light source module can be resolved; the reworking or reusing of the dismounted light source module is facilitated.
Description
technical field [0001] The invention relates to a backlight module, in particular to a backlight module whose light source module can be easily disassembled. Background technique [0002] Electronic devices that cannot emit light by themselves, such as liquid crystal displays, are provided with a backlight module to provide the required backlight. Under the requirements of light and thin product design, the thickness of the backlight module is also reduced accordingly. Usually, an edge-lit type backlight module is used, and the light source module is made by carrying multiple light-emitting diodes on a circuit board. When the light source module is assembled with the support member (holder), between the circuit board and the support member, the circuit board is adhered to the support member with glue, so as to achieve the purpose of supporting and fixing the light source module. [0003] When the light source module needs to be detached from the support member for rework or...
