Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in utility model embodiment, carries out clear, complete to the technical scheme in this utility model embodiment
Ground describes, it is clear that described embodiment is a part of embodiment of this utility model rather than whole realities
Execute example.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative labor
The all other embodiments obtained under dynamic premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, the backlight module that this utility model embodiment provides, including elastic deformation can occur
The memory structures part 20 that backboard 10 is connected with the diapire of backboard, and printed circuit board (PCB) (not shown),
The inside of memory structures part 20 has heating wire 21, and the two ends of heating wire 21 electrically connect shape with printed circuit board (PCB)
Become heating circuit.
In the technical scheme of this utility model embodiment, utilize the shape memory effect of memory structures part 20,
By heating circuit, memory structures part 20 is heated, when heating-up temperature reaches the note of memory structures part 20
When recalling temperature, memory structures part 20 can bend, thus drives backlight module and display floater bending,
