Problems solved by technology

However, such frequent actions of pulling and inserting the lamp holder 108 in the frame 102 may easily cause the light guide plate 104 and the reflector 106 to be scratched by the friction of the lamp holder upper board 110 and the lamp holder lower board 112
Even, the lamp holder 108 made of rigid material is easily stretched and deformed by the light guide plate 104 and the reflector 106 during the drawing and insertion process, so that the openings of the lamp holder 108 are of different sizes.
Therefore, light leakage will occur, which will greatly affect the overall brightness of the backlight module 100.

Embodiment Construction

[0013] The present invention specially designs a backlight module, which inserts the lamp socket between the light guide plate and the side plate of the frame, so as to prevent the lamp socket from scratching the light guide plate and the reflection sheet. The consistency of the size of the opening of the lamp holder can be maintained, the occurrence of light leakage can be prevented, and the overall brightness of the backlight module can be improved.

[0014] Please also refer to Figure 2A and Figure 2B , respectively depicting a partial perspective view and a cross-sectional view of a backlight module according to a preferred embodiment of the present invention. exist Figure 2A and Figure 2B Among them, the backlight module 200 includes a frame 202 , a light guide plate 204 , a reflector 206 , a lamp holder 208 and a light source 214 , and the light guide plate 204 , the reflector 206 , the lamp holder 208 and the light source 214 are located in the frame 202 .

Abstract

The present invention relates to a backlight module, including frame, reflecting plate, light guide plate and lamp seat. The frame has frame side plate and frame bottom plate, the reflecting plate is placed on the frame bottom plate, and the light guide plate is placed on the reflecting plate, lamp seat has side plate, upper plate and lower plate, the side plate of the lamp seat is parallel to the side plate of frame, the upper plate and lower plate of lamp seat are connected with the plate of lamp seat. One end of lower plate of lamp seat is positioned on one end of reflecting plate and near by light guide plate, one end of upper plate of lamp seat is extended over the light guide plate, so that the lamp seat can be placed into or taken out between light guide plate and frame side plate along the normal direction perpendicular to the surface of bottom plate of frame.

Description

technical field [0001] The present invention relates to a backlight module, in particular to a backlight module capable of preventing a light guide plate and a reflector from being scratched when a lamp holder is taken out or inserted. . Background technique [0002] In today's technology-changing era, backlight modules have been used in electronic devices such as liquid crystal displays (LCDs), mobile phones, and personal digital assistants (PDAs) to provide the light required by the above-mentioned electronic devices. . [0003] Please also refer to Figure 1A and Figure 1B , which respectively depict a partial perspective view and a cross-sectional view of a conventional backlight module. exist Figure 1A and Figure 1B Among them, the backlight module 100 includes a frame 102 , a light guide plate 104 , a reflector 106 , a lamp holder 108 and a cold cathode fluorescent lamp (CCFL) 114 . The light guide plate 104 , the reflector 106 , the lamp holder 108 and the col...
