Description
Technical field
The present invention relates to display screen technology fields, more particularly to a kind of design of flexible display.
Background technique
Dimension display technologies are also one of display screen the main direction of development, in existing dimension display technologies, are usually enabled
User's right and left eyes generate visual difference, to obtain the visual experience of similar three-dimensional in brain.But this technology experience sense is poor,
Viewing time be easy to cause user's dizziness and nausea too long.The difference of stereo-picture and flat image is that solid figure also has
" depth ".
Flexible and transparent display screen is the New LED display technology developed rapidly in recent years, because of its flexible energy
By force, frivolous to be not take up space, it is widely used in the positions such as glass, show window, glass curtain wall.The appearance of flexible and transparent display screen,
So that multilayer video screen Overlapping display 3-D image becomes possibility.Such as the patent of invention of Publication No. 108398801A, it is public
A kind of naked eye 3D display structure and its display screen, including Multi-level display layer are opened, display layer described in multilayer successively stacks, every layer of institute
Stating display layer includes multiple pixels, and the position of the pixel is corresponding on the different display layers, from display layer described in the first floor to tail
The corresponding pixel of the layer display layer successively misplaces a certain distance towards the same direction.The patent is by causing viewer two
Visual difference achieve the purpose that Three-dimensional Display, obtain display screen flexible when using flexible substrate.But user is watching
When be easy to produce the symptom of feeling of fatigue and dizzy nausea, experience sense is bad.And the flexible display screen for being worse than single layer, bending
Limitation, impact resistance is not high, and the practicability is poor.
Summary of the invention
The present invention provides a kind of flexible display for the problem of the flexible difference of three-dimensional display screen in the prior art.
Present invention employs several luminescent fibres, common " face " is replaced to play image with " point " of several dispersions, because
This does not need complete " face ", does not have to the flexible degree and shock resistance degree that consider " face ", therefore display screen is flexible big, bending
Degree is high, effectively prevent hitting and damage.Using flexible material, effectively diminution volume, storage convenient for folding is truly realized and takes with oneself
Band.It, can be while guaranteeing that image clearly is complete by the arrangement mode of spacing and luminescent fibre between setting LED chip
" depth information " of 3-D image is provided, viewer is allowed to obtain 3D vision experience.3-D effect is more naturally, usage comfort
It is high.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of flexible display, including foreboard, flexible substrate and several luminescent fibres, foreboard and flexible substrate are mutually flat
It goes, conductive film is fixedly connected in flexible substrate, conductive film is equipped with control circuit, luminescent fibre one end and control circuit
Connection, the other end are connect with foreboard；Luminescent fibre includes matrix, several LED chips and conductive element identical with LED chip quantity
Part, LED chip are correspondingly connected with towards foreboard, LED chip with conducting element along luminescent fibre axial alignment, LED chip light-emitting surface,
Conducting element connects to the control circuit；Matrix is encapsulated in LED chip and conducting element periphery；Foreboard, matrix and conducting element are saturating
It is bright.
Preferably, further including frame, frame is fixedly connected with flexible substrate and foreboard respectively, frame, flexible substrate and
Foreboard surrounds a closed cavity out.
With modern science level, LED chip can be made very miniature, and because LED chip can regard point light source as, put light
Source light emits around, and refraction, reflection and scattering, the vision finally generated occur when passing through different medium for the light of transmitting
The similar circle halation around point light source of effect, can regard a biggish luminous point as.In order to optimize visual effect, can also add
Guide-lighting patch.Etched circuit on conductive film, LED chip pass through conducting element and circuit connection, conductive film light weight, thickness
It is small, it can bend.It is imaged using " point " collective effect on several luminescent fibres, it, will instead of " face " in the prior art
The bending problem in " face " switchs to the storage problem of simple " point ".When display screen is impacted, active force can not act on aobvious
Show " face " of device, therefore the problem of be not in screen fragmentation in the prior art.Flexible material can move under force and
Deformation, and movement and deformation in most cases can't be damaged to flexible material itself, therefore can imitate and shed energy, tool
There is shock proof effect.Compared with prior art, the present invention is flexible stronger, bends more flexible, more difficult damage.
Preferably, the region where setting the tie point of luminescent fibre and foreboard is the first bonding pad, with conductive film
Region where tie point is the second bonding pad, and the tie point of luminescent fibre and foreboard is distributed in the first bonding pad, and shine fibre
Dimension and the tie point of conductive film are distributed in the second bonding pad；The shape phase of the shape of first bonding pad and the second bonding pad
Seemingly, the first bonding pad area is greater than the second bonding pad area.Preferably, being with the junction of luminescent fibre and conductive film
Point makees the extended line of luminescent fibre, and the extended line of all luminescent fibres intersects in same point.First bonding pad can be regarded as to
The projection of two bonding pads, luminescent fibre regard projection ray as, and the extending line intersection point of luminescent fibre regards projection light source as.Due to shining
Fiber is not parallel to each other, and therefore, the light that LED chip issues will not be blocked, and in addition the setting of similar projection can enable generation
Light carries depth information, and the 3D visual effect of generation is more naturally, comfort level is high.
Preferably, frame includes flexible bezel and bracket, flexible bezel is fixedly connected with foreboard and flexible substrate respectively,
Flexible bezel is equipped with mounting groove, and bracket shape matches with mounting groove.Bracket is used to support display, when taking branch bracket away
When, it is flexible very high since the structure almost all in region is fabricated from a flexible material, folding can be rolled, is taken up space small,
It is easy to carry, it is hardly damaged.Bracket can match the display under differently curved degree there are many shape, can also use elastic material
Material cooperation fixing piece is made, and is fixed when by screen-bending to satisfied degree by fixing piece, can also be with composable or deform
Structure.
Preferably, bracket includes several rigid support pieces, rigid support piece is hinged to form bar shaped entirety, both ends
Rigid support on piece is equipped with buckle.It is one folded that articulated structure enables rigid support piece to build up, and rigid support piece is also avoided to fall
It loses, is easy to use and stores, buckle for connecting head and the tail two panels support chip.
Preferably, matrix is flexible insulation resin, conducting element is transparent conductive film.It can be softer saturating of quality
Bright insulating resin plays the role of protection, positioning and support.Using material flexible, or the material of more " soft ", so that hair
Fiber optics arbitrarily can be folded or be crimped when not in use in display screen, be convenient for carrying storage, be also less likely to be damaged, when in use
It is easy to get desired curvature.Such as polyether-ether-ketone, polyimides, polyamidoimide, carboxymethyl cellulose-cellulose fiber
Tie up composite material etc..
Preferably, luminescent fibre includes several layers, each layer at least encapsulates 1 LED chip and 1 electrically conducting transparent is thin
