Description
Technical field
The present invention relates to field of display technology more particularly to a kind of ultra-thin curved-surface display devices.
Background technique
With the continuous progress of technology, electronic product stature relevant to display panel thins down, and weight also becomes
It obtains more and more lighter.Super basis, ultra thin handset, tablet computer, ultrathin display, ultra-thin television are all related with " ultra-thin, ultralight "
Product, be all the preference by user.
Again to LED backlight from CRT to LCD, display panel is constantly evolved, while also being become in appearance thin.For
The appearance of display panel, user are pursuing always ultimate attainment frivolous such as " knife edge ".In fact, display panel is as people, outside
Sight is first impression, and the outstanding ultra-thin display panel of a appearance can allow user to have a pleasant usage experience first.
Nowadays, in order to pursue more preferably viewing effect, curved surface TV comes into being, compared with flat-surface television, curved surface TV
With systems such as more smooth curved appearance moulding, outstanding contrast, wider visual angle, picture telepresencs more true to nature
Column advantage, however, ultra-thin curved surface all-in-one machine dog-eat-dog currently on the market, as thickness is more and more thinner, mechanism member intensity is got over
Come it is weaker, in use display panel easily with light guide plate occur dislocation rebound and cause curature variation, lead to ultra-thin song
Surface TV maintains curvature to become problem, can not accomplish so as to cause product ultimate attainment thin.
Summary of the invention
In view of the shortcomings of the prior art, the present invention provides the ultra-thin curved-surface displays that one kind can maintain constant curvature
Device.
In order to achieve the above purpose, present invention employs the following technical solutions:

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 and Fig. 2, the ultra-thin curved-surface display device of the embodiment of the present invention include display panel 10, optical diaphragm group
20, light guide plate 30 and the outline border 100 of protection and position-limiting action, optical diaphragm group 20 are fitted in the light-emitting surface of light guide plate 30
On, light guide plate 30 has different bending curvatures, and two opposite ends tilted on the light-emitting surface of light guide plate 30 from display panel 10
With tilted on display panel 10 two opposite ends difference it is relatively fixed, outline border 100 is by display panel 10, optical diaphragm group 20 and leads
Tabula rasa 30 is surrounded in it, and is defined to the location and shape of display panel 10 and light guide plate 30.
Two opposite ends of display panel 10 are tilted relative to the middle part of display panel 10, and two opposite ends of light guide plate 30 are opposite
It is tilted in the middle part of light guide plate 30, and light guide plate 30 has different bending curvatures from display panel 10, when light guide plate 30
After both ends are mutually preferably attached to the back of display panel 10, certain gap is formed between light guide plate 30 and display panel 10, and it is outer
Light guide plate 30 and display panel 10 are accommodated therein by frame 100 simultaneously, pass through the limit to light guide plate 30,10 end of display panel
Position can assist the curvature for maintaining the two no longer to change, and the bounce of curved light guide plate 30 and the cooperation generation of outline border 100 makes
The curvature of display panel 10 can remain constant.After optical diaphragm group 20 fits to 30 surface of light guide plate, middle part and display
There are still certain intervals between panel 10.
Two opposite ends tilted on the light-emitting surface of light guide plate 30 as one of preferred embodiment and display panel
Two opposite ends tilted on 10 are pasted together by transparent colloid, for example, using optics glue.Here, optical diaphragm
Group 20 is in the width for tilting the width on direction and being less than light guide plate 30, so that the edge of optical diaphragm group 20 and light guide plate 30 are stuck up
There is interval between the end risen, the both ends of light guide plate 30 is facilitated to be bonded fixation with display panel 10, is i.e. optical diaphragm group 20
Edge and light guide plate 30 form step-like structure, and transparent colloid is filled between the step-like structure and display panel 10.
As shown in figure 3, outline border 100 includes the annular sidewall 101 of surrounding, covers the front cover for being located at the arc of 101 side of side wall
Plate 102 and lid are located at the back shroud 103 of the arc of 101 other side of side wall；Front shroud 102 is the plate body of annular, is fitted in aobvious
Show that the edge of panel 10, the end face that 30 Elastic pusher back shroud 103 of light guide plate tilts display panel 10 are connected in side wall 101
Surface.The edge of the display surface of display panel 10 is connected to 102 inner surface of front shroud, front shroud 102, side wall 101 and back shroud
103 are held at the edge at the edge of light guide plate 30 and display panel 10 wherein.To which front shroud 102 and side wall 101 surround guarantor
The front frame of display panel 10 is protected, back shroud 103 and side wall 101 surround the after-frame of protection light guide plate 30.
In order to promote light utilization, ultra-thin curved-surface display device also has reflector plate 40, which, which is fitted in, leads
One side of the tabula rasa 30 far from light emission side, is also housed by outline border 100.Also, it is also fitted with one layer on the surface of reflector plate 40 to dissipate
Hot plate 50, the heat sink 50 and light guide plate 30 lean on side where close to sources backwards to setting, convenient for preferably distributing light source generation
Heat.
At the back of outline border 100, through-hole 103a is offered on back shroud 103, heat sink 50 is arranged in through-hole 103a, excellent
It selects the end face of heat sink 50 non-bulging in back shroud 103, avoids the structural member in display device from being exposed to outer and dry vulnerable to external force
Optical components such as driving light guide plate 30 are related to, display defect is caused.
Such as Fig. 3, it is also provided with the threaded hole worn for hold-down bolt 110 on back shroud 103, hold-down bolt 110 is arranged in
Light guide plate 30 is pushed in threaded hole and towards display panel 10, preferably hold-down bolt 110 is multiple, is symmetricly set on back shroud 103
Two tilt ends.If necessary, light guide plate 30 and display surface can further be compressed and tightening hold-down bolt 110 of two sides
The tilting end of plate 10, is firmly combined the two without relative dislocation occurs.Side wall 101 preferably as shown in figure 3, with
View direction is vertical, and after hold-down bolt 110 is tightened, the tilting end end of light guide plate 30 and display panel 10 is fitted in side wall completely
101 inner surfaces.
The present invention both makes to have different curvature by the way that display panel to be bent respectively with light guide plate, and by the two
Both ends are separately fixed at together, are tightened power using what is generated therebetween and are maintained the curvature of display device, so that ultra-thin song
Flat-panel display device remains to securely maintain constant curvature.
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.
