Abstract
The utility model relates to electronic product backlight production technical field, refer in particular to the narrow frame backlight source of a kind of modified, it comprises photomask, upper bright enhancement film, lower bright enhancement film, diffusion barrier, light guide plate, reflector plate, metal frame, LED lamp bar, the lower end of photomask is provided with bright enhancement film successively, lower bright enhancement film, diffusion barrier, light guide plate, reflector plate, metal frame, light guide plate is provided with LED lamp bar, in utilization, bright enhancement film protrudes several ear, photomask pastes the fixing ear that bright enhancement film protrudes, photomask is pasted onto on metal frame simultaneously, fix the optical film material in metal frame and light guide plate, thus reach the limit of backlight from outside to light-emitting zone and do narrow effect, some small gaps are done on the every limit of metal frame surrounding, for a glue, thus strengthen the viscosity of backlight and LCD.When mobile phone falls or vibrate, backlight does not have and loosens or come off.
Description
Technical field:
The utility model electronic product backlight production technical field, refers in particular to the narrow frame backlight source of a kind of modified.
Background technology:
Along with the development of mobile phone technique, people more and more want when mobile phone profile is constant, and it is larger that mobile phone viewing area can be done, and is convenient for people to use.
At present, the distance Sharp of LCD of mobile phone from outside to viewing area and LG have accomplished 0.6mm, the limit of LCD display is done narrower and narrower, need the limit of backlight from outside to light-emitting zone more and more narrow simultaneously, also need the shading glue by backlight and LCD are pasted to do narrower and narrower, shading glue does narrow rear viscosity and can decline, when mobile phone falls or vibrates, backlight has the possibility loosening or come off, thus affects the display effect of mobile phone.
Utility model content:
The object of the invention is for the deficiencies in the prior art, adopt metal as backlight housing, in utilization, bright enhancement film protrudes several ear, photomask pastes the fixing ear that bright enhancement film protrudes, and is pasted onto on metal frame simultaneously, fixes the optical film material in metal frame and light guide plate by photomask, thus reach the limit of backlight from outside to light-emitting zone and do narrow effect, some small gaps are done on the every limit of metal frame surrounding, for a glue, thus strengthen the viscosity of backlight and LCD.When mobile phone falls or vibrate, backlight does not have and loosens or come off.
For achieving the above object, the utility model adopts following technical scheme: it lower end comprising photomask is provided with bright enhancement film, lower bright enhancement film, diffusion barrier, light guide plate, reflector plate, metal frame successively, light guide plate is provided with LED lamp bar, upper bright enhancement film is protruding with fixing ear, photomask is pasted onto on fixing ear, metal frame surrounding is provided with breach, and metal frame surrounding is also provided with the mounting groove installing fixing ear.
Described fixing ear is two or more.
Described breach is two or more.
The utility model beneficial effect is: the lower end of photomask is provided with bright enhancement film successively, lower bright enhancement film, diffusion barrier, light guide plate, reflector plate, metal frame, light guide plate is provided with LED lamp bar, upper bright enhancement film is protruding with fixing ear, photomask is pasted onto on fixing ear, metal frame surrounding is provided with breach, in utilization, bright enhancement film protrudes several ear, photomask pastes the fixing ear that bright enhancement film protrudes, photomask is pasted onto on metal frame simultaneously, fix the optical film material in metal frame and light guide plate, thus reach the limit of backlight from outside to light-emitting zone and do narrow effect, some small gaps are done on the every limit of metal frame surrounding, for a glue, thus strengthen the viscosity of backlight and LCD.When mobile phone falls or vibrate, backlight does not have and loosens or come off.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention:
See shown in Fig. 1 to Fig. 2: the lower end that the utility model comprises photomask 1 is provided with bright enhancement film 2, lower bright enhancement film 3, diffusion barrier 4, light guide plate 5, reflector plate 6, metal frame 7 successively, light guide plate 5 is provided with LED lamp bar 8, upper bright enhancement film 2 is protruding with fixing ear 21, photomask 1 is pasted onto on fixing ear 21, metal frame 7 surrounding is provided with breach 71, and metal frame 7 surrounding is also provided with the mounting groove 72 installing fixing ear 21.
Described fixing ear 21 is two or more.
Described breach 71 is two or more.
Adopt metal as the metal frame 7 of backlight 8, photomask 1 is pasted onto on four flangings of metal frame 7 simultaneously, can can fix display screen 9 again by fixed optics film material, display screen 9 is provided with touch-screen 11, metal frame 7 limit is fixed in mobile phone shell 10, so just be equivalent to indirectly be pasted onto in mobile phone shell by display screen 9, under square one, when mobile phone profile is constant, viewing area can be accomplished maximum.Photomask 1 pastes the fixing ear 21 that bright enhancement film 2 protrudes, photomask 1 is pasted onto on metal frame simultaneously, fix the optical film material in metal frame and light guide plate 5, thus reach the limit of backlight from outside to light-emitting zone and do narrow effect, some breach 71 are done on the every limit of metal frame surrounding, for a glue, thus strengthen the viscosity of backlight and LCD.When mobile phone falls or vibrate, backlight does not have and loosens or come off.
The above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
