Description
Technical field
The present invention relates to a kind of backlight module (backlight module), particularly relate to a kind of backlight module that can avoid lamp socket (lamp holder) scratch light guide plate (light guide plate) and reflector plate (reflector) when being removed or being placed into.
Background technology
In the epoch that science and technology is maked rapid progress now, backlight module has been applied to LCD (liquid crystal display, LCD), mobile phone and personal digital assistant (personal digitalassistant, PDA) etc. in the electronic installation, to provide above-mentioned electronic installation required light.
Please be simultaneously with reference to Figure 1A and Figure 1B, it has illustrated the part stereographic map and the cut-open view of traditional backlight module respectively.In Figure 1A and Figure 1B, backlight module 100 comprises framework 102, light guide plate 104, reflector plate 106, lamp socket 108 and cold-cathode tube (cold cathode fluorescent lamp, CCFL) 114.Light guide plate 104, reflector plate 106, lamp socket 108 and cold-cathode tube 114 all are positioned at framework 102.Wherein, framework 102 comprises chassis base 103 and framework side plate 105, the vertical connection of an end of framework side plate 105 and chassis base 103.Reflector plate 106 is disposed on the chassis base 103, and light guide plate 104 is disposed on the reflector plate 106.
In addition, lamp socket 108 comprises lamp socket side plate 109, lamp socket upper plate 110 and lamp socket lower plate 112, and lamp socket upper plate 110 and lamp socket lower plate 112 are connected with the two ends of lamp socket side plate 109, and lamp socket upper plate 110 and lamp socket lower plate 112 are all on the side perpendicular to lamp socket side plate 109.Wherein, lamp socket side plate 109 touches with the 105 parallel subsides of framework side plate, and an end of framework lower plate 112 is between an end and chassis base 103 of reflector plate 106, and contacts with reflector plate 106 and chassis base 103.One end of framework upper plate 110 is positioned on the light guide plate 104, and contacts with light guide plate 104.Therefore, framework upper plate 110 and framework lower plate 112 are clamped light guide plate 104 and reflector plate 106 up and down.Cold-cathode tube 114 is disposed in the lamp socket 108, in order to provide backlight module 100 required light.
When the user will change cold-cathode tube 114 in the backlight module 100, because the opening between framework upper plate 110 and the framework lower plate 112 contains light guide plate 104 and reflector plate 106, the user can only extract or insert lamp socket 108 out in framework 102, to change action along the axial direction of the cold-cathode tube 114 shown in the arrow 150 of Figure 1A.Yet, so frequently pull and push the action of lamp socket 108 in framework 102 and cause light guide plate 104 and reflector plate 106 to be subjected to the friction of lamp socket upper plate 110 and lamp socket lower plate 112 and scratch easily.Even the lamp socket 108 that the rigidity material constituted is strutted by light guide plate 104 and reflector plate 106 easily in the process of pulling and pushing and is out of shape, and makes the openings of sizes of lamp socket 108 differ.Therefore, will cause the generation of light leakage phenomena, influence the overall brightness of backlight module 100 greatly.
Summary of the invention
The object of the present invention is to provide a kind of backlight module, its lamp socket can be along being removed or being placed between light guide plate and the framework side plate perpendicular to chassis base normal to a surface direction.Scratch light guide plate and reflector plate when the present invention can avoid lamp socket to be removed or to insert, and prevent lamp socket distortion and influence the consistance of the openings of sizes of lamp socket, the generation of light leakage phenomena prevented, with the overall brightness of raising backlight module.
According to purpose of the present invention, a kind of backlight module is proposed, comprise framework, reflector plate, light guide plate and lamp socket at least.Framework has an interconnective chassis base and a framework side plate, and reflector plate is disposed on the chassis base, and light guide plate is disposed on the reflector plate.The opening surface of lamp socket is to light guide plate, and lamp socket disposes between light guide plate and the framework side plate, and is positioned on the reflector plate.Lamp socket can be along being placed into or being removed between light guide plate and framework side plate perpendicular to chassis base normal to a surface direction.
According to purpose of the present invention, reintroduce a kind of backlight module, comprise framework, reflector plate, light guide plate and lamp socket at least.Framework comprises chassis base and framework side plate, the vertical connection of an end of framework side plate and chassis base.Reflector plate is disposed on the chassis base, and light guide plate is disposed on the reflector plate, and an end of light guide plate than an end of reflector plate further from the framework side plate.Lamp socket comprises lamp socket side plate, lamp socket upper plate and lamp socket lower plate, and the lamp socket side plate is parallel with the framework side plate, and lamp socket upper plate and lamp socket lower plate are connected with the two ends of lamp socket side plate are vertical respectively.Because an end of lamp socket lower plate is positioned on this end of reflector plate and near this end of light guide plate, add that an end of lamp socket upper plate extends the top of this end of light guide plate, make lamp socket be placed into or to be removed between light guide plate and framework side plate along surface normal direction perpendicular to chassis base.
