Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a conventional display panel. Referring to fig. 1, the display panel includes a display module 01. The display module 01 includes a display area 011 and a non-display area 012 surrounding the display area 011. A binding region 013 is also provided in the non-display region 012. The binding region 013 is spaced apart from the display region 011. A plurality of connection pins (not shown in fig. 1) are disposed in the bonding region 013, and the connection pins are used for bonding and electrically connecting with other electronic devices (such as a driving chip or a flexible circuit board, etc.) to drive the display panel to perform normal operation.
In the existing display panel, the display area 011 and the binding area 013 are located on the same plane, and since the binding area 013 cannot display an image, the setting of the binding area 013 can increase the area of the non-display area 012 of the display panel, so that the screen occupation ratio is greatly influenced, and the realization of a real comprehensive screen is not facilitated.
Specifically, with continued reference to fig. 1, the non-display area 012 is divided into four sub-areas, namely, a first sub-non-display area 0121, a second sub-non-display area 0122, a third sub-non-display area 0123, and a fourth sub-non-display area 0124. Wherein, the first sub non-display area 0121 is located at the left side of the display area 011, and its minimum width is a. The second sub non-display area 0122 is located at the right side of the display area 011 and has a minimum width b. The third sub non-display area 0123 is located at the upper side of the display area 011 and has a minimum width c. The fourth sub non-display area 0124 is located at the lower side of the display area 011 and has a minimum width d. With current technology, the dimensions of a, b and c can all be achieved to less than 1 mm. Since the binding region 013 is disposed in the fourth sub non-display region 0124, the size of d is at least greater than 3 mm. Obviously, this greatly affects the screen occupation ratio, contrary to the development trend of the full screen.
In view of this, an embodiment of the present invention provides a display panel. Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Referring to fig. 2, the display panel includes a display module 1 and a support structure 2. The display module 1 includes a first flexible substrate 11, the first flexible substrate 11 includes a display portion 111, a binding portion 112, and a bending portion 113 connecting the display portion 111 and the binding portion 112; the binding part 112 is provided with at least one connection pin (not shown in fig. 2) for binding and electrically connecting with other electronic devices; the supporting structure 2 comprises a first surface 21 and a second surface 22 which are parallel to each other, and a third surface 23 connecting the first surface 21 and the second surface 22, the display portion 111 is attached to the first surface 21, the bending portion 113 is attached to the third surface 23, and the binding portion 112 is attached to the second surface 22; the third surface 23 is shaped as a convex arc.
A display area is provided in the display unit 111, and a binding area is provided in the binding unit 112. The connection pins are located within the bonding region. The regions of the first flexible substrate 11 other than the display region are non-display regions, and thus the non-display regions include the bonding regions. The display section 111 is provided therein with a plurality of pixel units (located in the display area), and a drive circuit for driving the pixel units to perform an image display area. The driving circuit is electrically connected with the connecting pins in the binding region through the connecting wires. The binding region is used for binding with electronic devices such as a driving chip or a flexible circuit board and the like so as to drive the display panel to normally work or detect existing devices (such as a driving circuit and the like) on the display panel.
Compare fig. 1 and fig. 2, in this application technical scheme, still include bearing structure 2 through setting up display panel, and set up display portion 111 and binding portion 112 and laminate with two surfaces that are parallel to each other in bearing structure 2 respectively, it is relative with the light-emitting side one side to buckle to display panel in the essence in fig. 1 at least partial fourth sub non-display area 0124 (be binding portion 112 in fig. 2), like this when the user observes from the light-emitting side, observable fourth sub-non-display area 0124's area reduces, solved among the current display panel, because the area of binding can't carry out image display, the area of display panel non-display area can be increased in the setting of binding the district, and then the problem of very big influence screen area, realized reducing the area of non-display area from the vision, and then improve the purpose of screen area.
Further, it is considered that if the third surface 23 is a plane and the third surface 23 is perpendicular to the first surface 21, a junction of the third surface 23 and the first surface 21 forms a right angle, while a junction of the third surface 23 and the second surface 22 forms a right angle. The right angle easily "punctures" the bending portion 113, and further causes the connection wires for connecting the driving circuit and the connection pins to be broken, resulting in poor display of the display panel.
In the above technical solution of the present application, by setting the third surface 23 to be an arc shape protruding outward, the bending portion 113 can be bent along the arc-shaped third surface 23, so as to support and fix the bending portion 113 by using the third surface 23, and prevent the bending portion 113 from being damaged in the subsequent process or in the use process, and no right angle or acute angle occurs at the connection between the third surface 23, the third surface 23 and the first surface 21, and at the connection between the third surface 23 and the second surface 22, and the bending portion 113 is not "punctured".
Optionally, in the above technical solution, the display module 1 is a liquid crystal display module or an organic light emitting display module, and the like, which is not limited in this application.
Fig. 3 is a schematic structural diagram of another display panel according to an embodiment of the present invention. If the display module is a liquid crystal display module, optionally, referring to fig. 3, the display panel further includes a polarizer body 31 and an adhesive layer 32; the polarizer body 31 is located between the display portion 111 and the first surface 21, the adhesive layer 32 bonds the polarizer body 31 and the display portion 111, and the adhesive layer 32 bonds the bending portion 113 and the third surface 23, and bonds the binding portion 112 and the second surface 22.
Fig. 4 is a schematic structural diagram of a polarizer according to an embodiment of the present invention. Referring to fig. 4, the polarizer includes a surface protection film 34, a polarizer body 31, an adhesive layer 32, and a release film 33, which are sequentially stacked. When the polarizer needs to be attached to the display module, the release film 33 in the polarizer is peeled off to expose the adhesive layer 32, and the polarizer body 31 is attached to the display module by using the adhesive layer 32. The surface protective film 34 functions to prevent scratches from being left when the polarizer is used. The polarizer body 31 includes a polarizing sublayer 311 and a protective layer 312 formed on both sides of the polarizing sublayer 311. Alternatively, the material of the polarizing sublayer 311 includes iodine and polyvinyl alcohol (PVA). The material of the protective layer 312 includes Triacetylcellulose (TAC) or Cyclic Olefin Polymer (COP), or the like.
With reference to fig. 3 and 4, in the above technical solution, by providing that "the polarizer body 31 is located between the display portion 111 and the first surface 21, the adhesive layer 32 bonds the polarizer body 31 and the display portion 111, and at the same time, the adhesive layer 32 bonds the bending portion 113 and the third surface 23, and bonds the binding portion 112 and the second surface 22", the display module 1 and the support structure 2 are substantially bonded into a whole by using the adhesive layer 32 in the polarizer. The arrangement does not need to additionally coat adhesive, and the manufacturing process of the display panel can be reduced. And the thickness of the display panel can be reduced relative to the scheme of additionally coating the adhesive.
In practice, manufacturers of display panels often do not produce polarizers. Polarizers are commercially available from other polarizer manufacturers. In the commercially available polarizer, as shown in fig. 4, the polarizer body 31 and the adhesive layer 32 are generally the same size. However, in FIG. 3, the size of the adhesive layer 32 is larger than that of the polarizer body 31, so that the portion of the adhesive layer 32 beyond the polarizer body 31 can be used to bond the bending portion 113 with the third surface 23 and bond the binding portion 112 with the second surface 22.
Fig. 5-7 are schematic structural diagrams of different states in the manufacturing process of the display panel in fig. 3. In actual manufacturing, optionally, first, before the display module 1 and the support structure 2 are attached to each other, the release film 33 in the polarizer is peeled off, so that the adhesive layer 32 is exposed. Next, referring to fig. 5, the polarizer body 31 is adhered to the display module 1 by the adhesive layer 32. At this time, according to the different corresponding positions of the polarizer body 31 and the display module 1, the polarizer body 31 may be divided into three parts, which are the first sub-polarizer 301, the second sub-polarizer 302, and the third sub-polarizer 303. The first sub-polarizer 301 is correspondingly attached to the display portion 11, the second sub-polarizer 302 is correspondingly attached to the binding portion 112, and the third sub-polarizer 303 is correspondingly attached to the bending portion 113. Next, comparing fig. 5 and fig. 6, the polarizer body 31 is cut, so that the second sub-polarizer 302 is separated from the first sub-polarizer 301, the third sub-polarizer 303 is separated from the first sub-polarizer 301, and the second sub-polarizer 302 and the third sub-polarizer 303 are removed, at this time, the portion of the adhesion layer 32 originally used for attaching the second sub-polarizer 302 to the binding portion 112, and the portion of the third sub-polarizer 303 attached to the bending portion 113 are exposed. Finally, referring to fig. 7 and 3, the surface of the first sub-polarizer 301 facing away from the display part 11 is bonded to the first surface 21; bending the bending portion 113 along the third surface 23; and the bending part 113 is adhered to the third surface 23 and the binding part 112 is adhered to the second surface 22 by the adhesive layer 32, so as to attach the display module 1 to the support structure 2.
Considering that the strength of the polarizer body 31 is relatively high, if the polarizer body 31 is directly bent, the polarizer body 31 is easily broken and damaged, and the display module 1 is further damaged. In the above scheme, the polarizer body 31 is cut, and the second sub-polarizer 302 and the third sub-polarizer 303 are removed, so that the thickness and strength of the film at the bending position can be reduced, and the bending stress can be reduced, thereby ensuring that the display panel has a high yield.
Fig. 8 is a schematic structural diagram of another display panel according to an embodiment of the present invention. If the display module is a liquid crystal display module, optionally, referring to fig. 8, the display panel further includes a polarizer body 31 and an adhesive layer 32; the polarizer body 31 includes a first sub-polarizer 301 and a second sub-polarizer 302; the first sub-polarizer 301 is located between the display part 111 and the first surface 21, and the adhesive layer 32 adheres the first sub-polarizer 301 to the display part 111; the second sub-polarizer 302 is located between the binding portion 112 and the second surface 22, and the adhesive layer 32 bonds the second sub-polarizer 302 to the binding portion 112; the adhesive layer 32 also bonds the bend 113 to the third surface 23.
In the above technical solution, by setting "the first sub-polarizer 301 is located between the display part 111 and the first surface 21, the adhesive layer 32 bonds the first sub-polarizer 301 to the display part 111; the second sub-polarizer 302 is located between the binding portion 112 and the second surface 22, and the adhesive layer 32 bonds the second sub-polarizer 302 to the binding portion 112; the adhesive layer 32 also bonds the bending portion 113 and the third surface 23 ", and substantially bonds the display module 1 and the support structure 2 together by the adhesive layer 32 in the polarizer. The arrangement does not need to additionally coat adhesive, and the manufacturing process of the display panel can be reduced. And the thickness of the display panel can be reduced relative to the scheme of additionally coating the adhesive.
In addition, in fig. 8, the second sub-polarizer 302 is disposed between the binding portion 112 and the second surface 22, and the binding portion 112 may be supported by the second sub-polarizer 302, so as to improve the strength of the binding portion 112 and prevent the damage thereof in a subsequent process or in a use process.
Similarly, in the polarizer commonly purchased, the sizes of the polarizer body 31 and the adhesive layer 32 are the same. However, in fig. 8, the size of the adhesive layer 32 is larger than the sum of the sizes of the first sub-polarizer 301 and the second sub-polarizer 302, so that the portion of the adhesive layer 32 beyond the first sub-polarizer 301 and the second sub-polarizer 302 may be used to bond the bending portion 113 to the third surface 23.
Fig. 9 and 10 are schematic structural diagrams of different states in the manufacturing process of the display panel in fig. 8. In actual manufacturing, optionally, first, before the display module 1 and the support structure 2 are attached to each other, the release film 33 in the polarizer is peeled off, so that the adhesive layer 32 is exposed. Next, the polarizer body 31 is bonded to the display portion 111 using the adhesive layer 32 (similar to fig. 5). At this time, according to the different corresponding positions of the polarizer body 31 and the display module 1, the polarizer body 31 may be divided into three parts, which are the first sub-polarizer 301, the second sub-polarizer 302, and the third sub-polarizer 303. The first sub-polarizer 301 is correspondingly attached to the display portion 11, the second sub-polarizer 302 is correspondingly attached to the binding portion 112, and the third sub-polarizer 303 is correspondingly attached to the bending portion 113. Referring to fig. 9, the polarizer body 31 is cut to separate the third sub-polarizer 303 from the first sub-polarizer 301, and separate the third sub-polarizer 303 from the second sub-polarizer 302, and the third sub-polarizer 303 is removed, at which time, the portion of the adhesive layer 32 originally used for attaching the third sub-polarizer 303 to the bending portion 113 is exposed. Finally, referring to fig. 10 and 8, the surface of the first sub-polarizer 301 facing away from the display part 11 is bonded to the first surface 21; bending the bending portion 113 along the third surface 23; bonding the binding portion 112 to the second surface 22; and the bending portion 113 is adhered to the third surface 23 by the adhesive layer 32, so as to attach the display module 1 to the supporting structure 2.
Considering that the strength of the polarizer body 31 is relatively high, if the polarizer body 31 is directly bent, the polarizer body 31 is easily broken and damaged, and the display module 1 is further damaged. In the above scheme, the polarizer body 31 is cut, and the third sub-polarizer 303 is removed, so that the thickness and strength of the film at the bending position can be reduced, and the bending stress is reduced, thereby ensuring the yield of the display panel.

Referring to fig. 11, if the display module 1 is a liquid crystal display module, the display panel further includes a backlight module; the backlight module is multiplexed as a support structure 2.
