Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to It is of the invention in limiting.
Refering to fig. 1~Fig. 3, the liquid crystal display device of the embodiment of the present invention include the main frame 10 of both ends open and are mounted on Light source assembly 20, optical module 30, liquid crystal display panel 40 and electric component 50, light source assembly 20 in main frame 10 can be use LED is also possible to CCFL (Cold Cathode Fluorescent Lamp, cathode fluorescent tube) as light as light source Source, electric component 50 include the components such as circuit board, control chip, loudspeaker.Liquid crystal display panel 40 is set to the light out of optical module 30 Side, the open end on main frame 10 far from liquid crystal display panel 40 are used to be fixed on extraneous stationary plane 1.Optical module 30 includes leading Tabula rasa 31 and optical diaphragm group 32, the light that light source assembly 20 issues uniformly project after 30 leaded light of optical module to liquid crystal display panel 40, eventually form display picture.
The stationary plane 1 is preferably the wall of white, is also possible to a part of furniture or electric appliance.Main frame is provided to inside The carrying of various components, defencive function, material can be engineering plastics or metal etc..Main frame component is completed Afterwards, it can be fixed in any position of user's needs, fixed form can be fastener and fix, paste.
By the way that main frame to be fixed on the extraneous stationary plane such as wall, display device and extraneous rigidity can be made stronger Stationary plane set it is integral, stationary plane can be used as the backboard and reflector plate of display device, ultra-thin and beautiful.Meanwhile user Corresponding hardware can be upgraded according to their own needs, easy to operate and upgrade cost is low.
Such as Fig. 4 and Fig. 5 a, the through-hole 11 and groove 12 being disposed adjacent are offered on main frame 10, optical module 30 is contained in In through-hole 11, electric component 50 is contained in groove 12.By the way that electric component 50 and optical module 30 are disposed on individually Two spaces, the guide-lighting performance of optical module 30 is more stable, and heat or electric signal etc. that electric component 50 generates are to optics group The interference of part 30 is smaller.Simultaneously as adjacent two sides, the thickness of display device is arranged in electric component 50 and optical module 30 It can accomplish several millimeters of thickness, be truly realized ultra-thin, also save space.
Such as Fig. 5 b, when 1 reflecting properties of the stationary planes such as wall are poor, can by optical module 30 far from liquid crystal display panel 40 side increases by one layer of reflector plate 70, to guarantee its higher reflection efficiency and display brightness.
Preferably to be limited to liquid crystal display panel 40, the light-emitting surface of the liquid crystal display device of the present embodiment in main frame 10 Side is also fitted with protecting frame 60, is covered on the open end on main frame 10 close to light-emitting surface side, at least partly to push down The edge of liquid crystal display panel 40.Specifically, protecting frame 60 includes strip parts 61 of the open end of covering groove 12 and from strip parts 61 The framework part 62 for extending and liquid crystal display panel 40 being limited.The groove 12 of strip parts 61 and main frame 10 cooperatively forms sky Electric component 50 is accommodated therein by chamber.Framework part 62 is fitted in 40 edge of liquid crystal display panel, fills to liquid crystal display panel 40 Decorations, protection and limit.
Further, a circle stage portion of connection through-hole 11 is formed with close to the side of light-emitting surface recess in main frame 10 13, the surrounding of liquid crystal display panel 40 is embedded and is fitted in the stage portion 13.Due to light source assembly 20, light guide plate 31 and optical diaphragm Group 32 is all in the through-hole 11 being arranged under stage portion 13, for the non-display area exposure for avoiding liquid crystal display panel 40, protecting frame 60 Part covering through-hole 11 is extended to towards centre, to block the position that light guide plate 31 and light source assembly 20 have a common boundary.
In conjunction with Fig. 6, here, the COF (Chip On Flex, or, Chip On Film, flip chip) of liquid crystal display panel 40 is held 400 are placed on the side in stage portion 13 close to groove 12, can use stage portion 13 and are fixed and support, while the end COF It is closer from the electric component 50 in groove 12, be conducive to shorten track lengths.It can correspond to and set in the strip parts 61 of protecting frame 60 There is array hole 610, which can be used as speaker hole, sound outlet hole and heat release hole, a Kong Duoyong simultaneously.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered It is considered as the protection scope of the application.
