Abstract

The invention relates to a backlight module and a photoelectric device, the backlight module comprises an optical plate and at least one light emitting element. The optical plate comprises a light-incoming face and a light-exiting face. The light emitting element is arranged on a circuit board and faces toward the light-incoming face, wherein, the light emitting element is magnetically absorbed on the optical plate by making use of at least one magnetic absorption member that is arranged on at least one or both of the optical plate and the circuit board. On account of using the magnetic absorption member for the assembly, the assembly positioning precision of the backlight module can be improved and the risk that the light emitting element is damaged can be reduced.

Description

technical field [0001] The invention relates to a backlight module and a photoelectric device, and in particular to a backlight module capable of precise positioning and assembly and a photoelectric device with a simple assembly procedure. Background technique [0002] In general liquid crystal displays, since the liquid crystal display panel (Liquid crystal display panel) does not have the function of actively emitting light, the liquid crystal display panel must be equipped with a backlight to display images. [0003] Figure 1A and Figure 1B It is a schematic diagram of a conventional side-type backlight module 100 . Please refer to Figure 1A , in the prior art, the circuit board 110 provided with the light emitting element 120 is fixed on the plastic frame 130 or the light guide plate 140 by using glue (not shown). However, the above method of fixing with glue is likely to cause a gap d between the light guide plate 140 and the light emitting element 120 due to the d...
