Description

Integrated backlight module with good soaking and radiating effect

Technical field

The utility model relates to a kind of backlight module, particularly relates to a kind of integrated backlight module with good soaking and radiating effect with a heat-conduction medium and a thermal conductive belt.

Background technology

LCD is at present by the display product that widely uses, and LCD to control the light transmittance of each location of pixels, makes LCD show image correctly by the liquid crystal layer of liquid crystal panel.At present, LCD be applied in large quantities TV, mobile phone (mobile phone), intelligent mobile phone (smart phone), mobile computer, with personal digital assistant (personal digital assistant, PDA) among.

Yet because liquid crystal panel belongs to non-self luminous demonstration material, therefore, LCD need dispose a backlight module so that its light source to be provided.Seeing also Fig. 1, is the combination sketch map of a main frame of a kind of existing LED-backlit module of commonly using and LCD.As shown in Figure 1; Usually; At least be equiped with two backlight modules 12 ' in the LCD; This two backlight module 12 ' is upper and lower side frame or the left and right side frame (as shown in Figure 1, this two backlight module 12 ' is the upper and lower side frame that relatively is arranged at main frame 11 ') that relatively is arranged at a main frame 11 ' of LCD.Wherein, each backlight module 12 ' is to comprise at least: a cover body 121 ', a circuit board 122 ' and a plurality of LED assemblies 123 '.

As everyone knows, when this a plurality of LED assembly 123 ' was luminous, this backlight module 12 ' can produce a hot stack phenomenon, and this hot stack phenomenon will impel the LGP or the blooming piece that are installed in the main frame 11 ' to produce deformation; Severe patient, the hot stack phenomenon will cause the damage of LGP or blooming piece, and make LCD show image normally.

Please continue to consult Fig. 2, the second combination sketch map of the main frame of existing LED-backlit module of commonly using and LCD.Because the hot stack phenomenon causes the damage of LGP or blooming piece; As shown in Figure 2; Part LCD manufacturer is only in this backlight module 12 ' of a frame of this main frame 11 ' installing, to slow down the hot stack phenomenon that LED assembly 123 ' is caused when luminous in backlight module 12 '.Yet such practice but on the contrary between the two side ends of LGP or blooming piece, causes a great temperature difference phenomenon; Such temperature difference phenomenon causes the deformation degree of two side ends of LGP or blooming piece different, and has influenced the balance of LCD outward appearance and attractive in appearance.

Because this hot stack phenomenon that is present in the LCD can't be enhanced effectively, therefore, many research documents and patent specification have proposed to improve the method for the hot stack phenomenon of backlight module; But, those research hot stack solutions that document and patent specification proposed, all by the mode of this cover body 121 ' of change or this circuit board 122 ' profile or material to reach the effect of heat radiation.Yet; Those hot stack solutions are effective when only terminating in backlight module 12 ' the independent use; When in case backlight module 12 ' is installed within this main frame 11 '; The heat that these a plurality of LED assemblies 123 ' are produced will be excluded from the outer of backlight module 12 ' and will be present between backlight module 12 ' and the main frame 11 ', be the hot stack phenomenon of the second layer.Owing between the basal surface of cover body 121 ' and main frame 11 ', be not intactly to fit; Therefore; Well imagine; Between the basal surface of cover body 121 ' and main frame 11 '; Still have the space, and the air among the space will become the thermally conductive heat resistance between cover body 121 ' and the main frame 11 ', make that the second layer hot stack phenomenon that is present between main frame 11 ' and the backlight module 12 ' can't be left through main frame 11 ' effectively.

Therefore, comprehensive above-mentioned for the explanation of the existing LED-backlit module of commonly using with the combination of the main frame of LCD, the combination that can learn the existing LED-backlit module of commonly using and the main frame of LCD has and still has many shortcomings and deficiency; In view of this; The creator of this case does one's utmost study and composition in addition; And a kind of integrated backlight module with good soaking and radiating effect of the utility model is accomplished in research and development finally; In order to solving the combination of the existing LED-backlit module of commonly using and the main frame of LCD simultaneously, hot stack phenomenon that it has and problem that can't samming.

This shows that above-mentioned existing LCD obviously still has inconvenience and defective, and demands urgently further improving in structure and use.Therefore how to found a kind of integrated backlight module that has that volume is little, cost is low concurrently and can have the new structure of comprehensive adjustment function when using, also become the improved target of current industry utmost point need with good soaking and radiating effect.
