Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing and specific embodiment party
Present invention is further described in detail for formula.
Embodiment 1:
The present inventor studies the structure inside the flexible display panels 10 of existing resilient flexibility.Such as figure
Shown in 2, the structures of flexible display panels 10 is that (an e.g. sub-pix or a pixel are adjacent several on island 102
Pixel)-bridge 101 (i.e. cabling)-gap 103 (region being hollowed out in flexible display panels 10) structure, be similarly to
The paper-cut of state.Point for the spherical jacking part 3a of rule, when flexible display panels 10 are jacked up, in flexible display panels
The drawing force of two side points by its up and down direction and the jacking part 3a thrust of bottom hemispheric.In view of spherical surface and flexibility
The attaching situation of display panel 10, apex and spherical shape attaching are best, when downward by top dome, attach along the downward curve of top dome
Situation is gradually deteriorated, and the resultant force (calling top power in the following text) of above-mentioned thrust and drawing force gradually becomes smaller.Therefore the flexibility at vertex position is aobvious
Show that panel 10 is maximum by top power, can balancing flexible display panel 10 shear stress；And the Flexible Displays face at more lower position
The top power that plate 10 is subject to becomes smaller, start when to lower can not active balance shear stress, to be easy to produce Flexible Displays face
The distortion of plate 10.
Based on the above analysis, referring to Fig. 3 and Fig. 4, the present embodiment provides a kind of bracket, including rack body 1, rack bodies

Mouthful, which further includes the jack-up structure for jacking up flexible display panels 10 along predetermined direction D0, and predetermined direction D0 hangs down
Directly in the slide surface of planar slide platform 2, jacking up structure includes jacking part 3a, and jacking part 3a with flexible display panels 10 for connecing
To jack up flexible display panels 10, the contact surface on the 3a of jacking part for being in contact with flexible display panels 10 meets: right for touching
In any truncation surface for crossing first straight line L1, the intersection of the truncation surface and contact surface includes: to be located at the two sides first straight line L1
The first sub- sub- intersection 4b of intersection 4a and second, first straight line L1 be by jacking part 3a vertex and perpendicular to planar slide platform
The straight line of 2 slide surface；The first sub- sub- intersection 4b of intersection 4a and second is gradually distance from first straight line L1 along first direction D1, the
One direction D1 is the direction contrary with jacking up；On first sub- intersection 4a apart from first straight line L1 it is farthest a little at curvature
Radius is greater than the upper radius of curvature at nearest any of first straight line L1 of the first sub- intersection 4a, and on the first sub- intersection 4a
Any two points are all satisfied: the radius of curvature at the farther away point of first straight line L1 is greater than or equal to closer apart from first straight line L1
Point at radius of curvature；It is sub to be greater than second for the radius of curvature at some place farthest apart from first straight line L1 on second sub- intersection 4b
On intersection 4b apart from first straight line L1 it is nearest a little at radius of curvature, and any two points on the second sub- intersection 4b are full
Foot: the radius of curvature at the farther away point of first straight line L1 is greater than or equal to the curvature at the closer point of first straight line L1
Radius.
It is described in detail below according to Fig. 3 and Fig. 4 current visual angle in the introduction of example.
