Abstract
The invention discloses a backlight module of a liquid crystal display. The backlight module comprises a light guide plate which comprises two lighting tube installing holes which are respectively arranged at two lateral side parts, two lighting tubes which are respectively arranged inside two lighting tube installing holes and a reflecting plate, three sides of which surround the light guide plate. The backlight module of the invention improves the luminous efficiency of the lighting tubes and the ray utilization rate and saves the cost at the same time.
Description
Technical field
The present invention relates to a kind of backlight liquid crystal display module, particularly a kind of module backlight that improves the fluorescent tube light utilization.
Background technology
The function of module backlight is to provide the area source that brightness is abundant and be evenly distributed to the LCD panel.Fig. 1 is the synoptic diagram of traditional side-light type module backlight, and as shown in the figure, module backlight mainly comprises light guide plate 1, reflector plate 2, fluorescent tube 3 and lamp tube cover 4, and wherein, fluorescent tube 3 is arranged at two incidence surface sides of this light guide plate respectively.The effect of light guide plate is the transmission direction of direct light line, and light is evenly penetrated by the exiting surface of light guide plate.
Behind the certain voltage of given fluorescent tube 3, fluorescent tube 3 beginnings are luminous, its light part directly enters light guide plate 1, another enters light guide plate 1 after than the reflection of many parts by lamp tube cover 4, in this process, owing to need the reflection of lamp tube cover 4, understand some light and be absorbed and see through, reduced the utilization factor of light.
Summary of the invention
The purpose of this invention is to provide a kind of module backlight, to the absorption of fluorescent tube light and the problem that penetrates, improve the utilization factor of light when solving the light that sends owing to lamp tube cover reflection fluorescent tube.
For achieving the above object, module backlight of the present invention comprises: light guide plate, and it includes two fluorescent tube mounting holes, and described two fluorescent tube mounting holes lay respectively at two side portion; Two fluorescent tubes place respectively in described two fluorescent tube mounting holes; Reflector plate, three bread enclose described light guide plate.
The two ends of described fluorescent tube are provided with the plastic mount that is used for fixing and locatees described fluorescent tube.
Described plastic mount comprises: the fluorescent tube patchhole, be embedded with conductive copper sheet clamping head, and make the electrode of fluorescent tube can directly insert described conductive copper sheet clamping head; The lamp tube wire hole is used to locate the lamp tube wire that is connected with described conductive copper sheet clamping head.
Described plastic mount also comprises reference column, is positioned at the bottom of described plastic mount.
Module backlight of the present invention by directly open circular hole on light guide plate, makes the fluorescent tube can be directly luminous in light guide plate, thereby has improved the luminescence efficiency and the light utilization of fluorescent tube; Module backlight of the present invention has saved lamp tube cover, has reduced the required material of light guide plate, thereby has provided cost savings.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Fig. 2 is the synoptic diagram of module backlight of the present invention, Fig. 3 is that the A-A of module backlight among Fig. 2 is to analysing and observe enlarged diagram, as shown in the figure, module backlight of the present invention, comprise: light guide plate 10, it includes two fluorescent tube mounting holes 11, and described two fluorescent tube mounting holes 11 lay respectively at two side portion of light guide plate 10; Two fluorescent tubes 30 place respectively in described two fluorescent tube mounting holes 11; Reflector plate 20, three bread enclose described light guide plate 10.
Last two fluorescent tube mounting holes 11 on the light guide plate 10, make the fluorescent tube 30 can be directly by passing in two fluorescent tube mounting holes 11 on the light guide plate 10, directly thereby luminous luminescence efficiency and the light utilization that has improved fluorescent tube in light guide plate 10 can also have been saved the cost of whole front panel.Light guide plate 10 adopts the technology manufacturing of ejection formation, and described two fluorescent tube mounting holes 11 are directly made when ejection formation is made light guide plate 10.Two fluorescent tube mounting holes 11 are respectively near two sides of light guide plate 10.
The two ends of fluorescent tube 30 are that high-pressure side and low pressure end are used plastic mount 50 respectively, 60 fixing and location, described high-pressure side plastic mount 50 is the same with the structure of low pressure end plastic mount 60, and its size is that the space of location, high-low pressure two ends varies in size can be different according to needs are installed.Traditional module backlight generally adopts rubber cap (Rubber Cap) to fix and locatees fluorescent tube, adopts the better plastic mount of hardness among the present invention.
Be that example illustrates high-pressure side and low pressure end plastic mount 50 with high-pressure side plastic mount 50 below, 60 structure: Fig. 4 is the schematic perspective view of fluorescent tube high-pressure side plastic mount, Fig. 5 is the front view of fluorescent tube high-pressure side plastic mount among Fig. 4, and Fig. 6 is the upward view of fluorescent tube high-pressure side plastic mount among Fig. 4.As shown in the figure, plastic mount 50 includes fluorescent tube patchhole 51, lamp tube wire hole 54 and reference column 53, and described fluorescent tube patchhole 51 is embedded with conductive copper sheet clamping 52, makes the electrode of fluorescent tube 30 can directly insert conductive copper sheet clamping 52.Conductive copper sheet clamping 52 is connected with lead in the lamp tube wire hole 54.When fluorescent tube is installed, only need electrode with fluorescent tube 30 directly insert conductive copper sheet clamping 52, just fluorescent tube 30 and lead can be communicated with, provide stable light source to module backlight.Reference column 53 is positioned at the bottom of plastic mount 50, is used to be supported in backboard or glue frame, and fluorescent tube is played positioning action.
The foregoing description only is used to illustrate the present invention, and those skilled in the art can make various modifications or replacement to embodiments of the invention, and does not depart from spirit of the present invention, and these modifications or replacement should be considered as dropping in protection scope of the present invention.
