Specific embodiment
It is further to a kind of technical solution work of display panel of the present invention below with reference to drawings and examples
Detailed description.
An embodiment of the invention provides a kind of display panel comprising substrate, the substrate include first,
The bending section of both second and connection, wherein described first for being arranged pixel, described second be progress bonding
Engaging portion, and the bending section is then to be turned to first top for described second, then described first and
Two are vertically connected with by a connection piece.Wherein in different embodiments, the display panel can be oled panel, LCD
Panel, micro LED panel, QD-OLED panel, AMOLED panel etc..
Refering to Figure 1, wherein the connector specifically includes stiffening plate (stiffner) 10.The wherein stiffening plate
Upper backboard (Back Plate, BP) 12 and lower backboard 14 are respectively equipped on 10 upper and lower surfaces, outside the upper and lower backboard 12,14
It is provided with the bending section 20 of the display panel.Wherein the backboard is a kind of membrane material structure, is used to support and sets with what it was attached
Other film layers on the substrate are set, the structure specifically used can be adds the glue material on surface to constitute by PET base material.
Further, wherein being formed between the end 122,142 of the upper and lower backboard 12,14 and the stiffening plate 10
The upper and lower notch 13,15 of one indent.Wherein the bending section 20 is extended outside the stiffening plate 10, and with the stiffening plate
A curved space is formed between 10 end 102.And in the present embodiment, as shown in the figure, the end of the stiffening plate
102 extend outwardly, and the inner surface of the curved space that its end surface and the bending section 10 are formed connects.
Wherein in conventional design, due to the bending section 20 be bending shape, with the upper and lower backboard 12,14
The position to connect will form the problems in stress collection such as A, B two o'clock position in figure.And in the present invention, due to it is described it is upper,
The presence of lower notch 13,15, so that having certain accommodating space between the end of the backboard and the stiffening plate 10, such as
This makes at the bending section 20 and backboard end connecting position (at A, B point in figure), in the effect of folding s tress
When oppressing the end of the backboard downwards down, the end of the backboard is enabled to have certain deformation accommodating space downwards, into
And the concentrated stress that the bending section is generated by bending at the position can be discharged to a certain extent.In this way, making described
Bending section should be the position that most strong stress is concentrated, can be effectively relieved instead therein at the position to connect with the backboard
Concentrated stress.As shown in the figure, the tergal position some arc-shaped deformations at A, B point are the deformation under stress, simultaneously
It is also the bending concentrated stress for alleviating the bending section of position at this.
Further, the notch between the end of the backboard and the stiffening plate, is also possible to a kind of gap, only
Guarantee not contacting not instead of directly between the end of the backboard and the stiffening plate, there are certain spare space,
This spare space can accommodate the stress deformation of the backboard end, and then play and alleviate the bending section and the backboard end
The stress that portion joint is generated because bending contact is concentrated.
Further, in different embodiments, wherein the shape of the notch and the abutted surface of the backboard can be
It is diversified, as long as guaranteeing there is accommodation space between the two.Specifically, it can be including arc surface, curve
Face, bending side and inclined surface etc., or it is also possible to the combined shaped after combining between above-mentioned shape.For example, curvilinear plane
With the combination shape of arc surface, bending side and the combination shape of inclined surface etc..Specifically can with the need depending on, and be not limited.And
And the shape that the above discloses also is only illustrative explanation, and non-limiting.
Further, it please refers to shown in Fig. 2~8, which illustrates the specific embodiment parties of a variety of notch abutted surface shapes
Formula, these embodiment illustrated are also only illustrative explanations, and are not limited.
Further, in different embodiments, the notch be additionally formed in the backboard end top or in
At portion position.
Wherein the apical position of the backboard end is arranged in the notch, due to the presence of the notch, so that described
Backboard and the contact length of the bending section joint are elongated, thus can alleviate the bending of the bending section to a certain extent
Degree, and then reduce folding s tress therein and concentrate.
And the notch is arranged at the medium position of the end, then as shown in figure 9, wherein the notch 13 is formed in
At the medium position of 12 end of backboard, wherein compressing of the upper end of the backboard 12 by bending stress, makes it downwards
It occurs bending and deformation, due to the presence of the notch 13, this deformation is accommodated by the notch 13.
Further, as shown in fig. 1, wherein the end 102 of the stiffening plate 10 is extend into the curved space, and
Connect with the inner surface of the curved space.Preferably, the stiffening plate end surface is arranged at arc surface, so that it is justified
Arc surface is bonded with the inner surface of the curved space, in this way, can also the bending region to the bending section 20 formed it is certain
Support, further alleviate the bending section 20 because bending caused by stress.
Further, in different embodiments, wherein the stiffening plate end is also possible to using its apex angle into fillet
The mode of setting.Wherein, the upper and lower apex angle that specifically can be the stiffening plate end is fillet setting, and fillet angle can
To be the bending angle with the bending section connecting position, so that the contact of the two is more bonded, and then pass through fillet top
Angle to carry out the bending section support up and down.
That is, the stiffening plate 10 extends into the curved space, can choose end surface with it is described curved
The mode that pars convoluta inner surface connects also can choose the mode that its end apex angle connects with the bending section inner surface, either
The combination of two ways.
A kind of display panel of the present invention uses completely new backboard end notches structure to design, so that the back
There is certain accommodating space between the end of plate and the stiffening plate.In this way, in the bending section and the backboard end
At connecting position, when the end of the backboard is oppressed downwards in the bending section under the action of folding s tress, so that the backboard
End can have certain deformation accommodating space downwards, and then the bending section at the position can be discharged to a certain extent
The concentrated stress generated by bending.So that the bending section at the position to connect with the backboard, should be most strong
The position that stress is concentrated, can be effectively relieved concentrated stress therein instead, and the stress for effectively improving its bending region is concentrated
Problem.
Technical scope of the invention is not limited solely to the content in above description, and those skilled in the art can not take off
Under the premise of from technical thought of the invention, many variations and modifications are carried out to above-described embodiment, and these deformations and modification should all
When within the scope of the present invention.
