技术领域 FIELD

[0001] 本发明涉及一种显示面板,尤其涉及一种可挠性显示面板。 [0001] The present invention relates to a display panel, particularly to a flexible display panel.

背景技术 Background technique

[0002] 随着显示技术的突飞猛进,显示器已从早期的阴极射线管(Cathode Ray Tube,CRT)显示器逐渐地发展到目前的平面显示器(Flat Panel Display, FPD)。 [0002] As display technology advances, the early display from a cathode ray tube (Cathode Ray Tube, CRT) displays gradually to the current flat panel display (Flat Panel Display, FPD). 相较于硬质载板(例如,玻璃基板)所构成的平面显示器,由于可挠性基板(例如,塑胶基板)具有可挠曲与耐冲击等特性,因此近年来已着手研究将主动元件制作于可挠性基板上的可挠式显示器。 Compared to the rigid carrier (e.g., glass substrate) composed of a flat display, since the flexible substrate (e.g., plastic substrate) having a flexible and impact resistance and other properties, so in recent years has begun to study the production of active device on a flexible substrate may be flexible display.

[0003] 在现有技术中,传统的可挠式显示器在制作时,会先在主动元件基板与对向基板之间涂布框胶,然后压合主动元件基板与对向基板,并将显示介质注入主动元件基板与对向基板之间,之后再进行密封。 [0003] In the prior art, a conventional flexible display in the production, will be in the first active device and the substrate to the coating of the sealant between the substrate and then laminated to the substrate and the active device substrate, and a display the active medium is injected between the element substrate and the opposing substrate, and then after sealing. 例如,框胶通常为热固性树脂或紫外线硬化胶,其在两基板(主动元件基板和对向基板)加热、加压进行压合后会硬化。 For example, the sealant is generally a thermosetting resin or an ultraviolet curing adhesive, which will harden after the two substrates (the active element substrate and the counter substrate) is heated, pressurized crimping. 然后,在可挠式显示器弯曲时,硬化的框胶往往会弯曲困难,甚至在弯曲过程中,硬化的框胶因受到过大的应力而产生损坏,造成基板断裂或主动元件被损坏,因而影响到产品的信赖性。 Then, when the flexible display is bent, the hardened sealant tends to bend difficult, even during the bending process, hardening the sealant by being subjected to excessive stress and cause damage, resulting in breakage or the active element is damaged substrate, thereby affecting the reliability of the product.

具体实施方式 detailed description

[0025] 为了使本申请所揭示的技术内容更加详尽与完备,可参照附图以及本发明的下述各种具体实施例,附图中相同的标记代表相同或相似的组件。 [0025] In order to make the technical contents disclosed herein and more detailed complete, various embodiments may be described below with reference to the accompanying drawings, and the present invention, the same or similar reference numerals represent the same components. 然而,本领域的普通技术人员应当理解,下文中所提供的实施例并非用来限制本发明所涵盖的范围。 However, those of ordinary skill in the art should understand that the embodiments hereinafter are not used for limiting the scope of the present invention. 此外,附图仅仅用于示意性地加以说明,并未依照其原尺寸进行绘制。 Further, the accompanying drawings are only illustrative and are, not made according to its original size.

[0026] 下面参照附图,对本发明各个方面的具体实施方式作进一步的详细描述。 [0026] Hereinafter, specific embodiments of various aspects of the present invention will be further described in detail with reference to the drawings.

[0027] 图I (a)示出现有技术中的可挠式显示面板的结构示意图。 [0027] FIG I (a) shows a schematic configuration of a prior art flexible display panel appears. 如图I (a)所示,该可挠式显示面板包括一第一基板101、一第二基板201和一框胶30,并且第一基板101位于第二基板201的上方,框胶30位于第一基板101与第二基板201之间。 FIG I (a), a flexible display panel which comprises a first substrate 101, a second substrate 201, and a sealant 30, and the first substrate 101 located above the second substrate 201, the sealant 30 is located 101 between the first substrate and the second substrate 201. 此外,在第一基板101的下方还设置一光学薄膜层103,在第二基板201的上方也设置一光学薄膜层203,藉由该光学薄膜层103和203和框胶30之间的接合从而形成一封闭空间,以便在该封闭空间中容置一显示介质,诸如,液晶分子。 Further, under the first substrate 101 is further provided an optical film layer 103, over the second substrate 201 is also provided an optical film layer 203, by engagement between the optical film layer 103 and 203 and the sealant 30 thereby forming a closed space, so as to receive a display medium in the closed space, such as, the liquid crystal molecules.

[0028] 在一些情形下,该可挠式显示面板中的可挠性部件并未发生弯曲,此时,第一基板101与第二基板201彼此平行,框胶30与光学薄膜层103的接合位置固定,并且框胶30与光学薄膜层203的接合位置固定。 [0028] In some cases, the display panel of the flexible member of the flexible bending does not occur at this time, the first substrate 101 and second substrate 201 parallel to each other, engaging the sealant 30 and the optical film layer 103 position is fixed, and the sealant 30 and the optical film layer 203 is fixed to the engaged position. 在另一些情形下,该可挠式显示面板中的可挠性部件出现弯曲,此时,第一基板101、第二基板201会发生一定程度地变形。 In other cases, the display panel of the flexible member may be a flexible bowing this case, the first substrate 101, second substrate 201 may be deformed to a certain extent occurs. 如前文所述,在现有技术中,框胶通常为热固性树脂或紫外线硬化胶,其在两基板101和201加热、加压进行压合后会硬化,如此一来,硬化后的框胶弯曲相对困难,甚至会因受到过大的应力而产生损坏,造成基板断裂或主动元件被损坏。 As previously described, in the prior art, the sealant is generally a thermosetting resin or an ultraviolet curing adhesive which is heated in the two substrates 101 and 201, after the pressure nip will be hardened, thus, after curing sealant curved relatively difficult even by exposure to generate excessive stress damage, resulting in breakage of the substrate or the active element is damaged.

[0029] 更具体地,图I (b)示出图I (a)的可挠式显示面板在弯曲时,基板与框胶间产生的应力导致基板断裂的状态示意图,图I (C)示出图I (a)的可挠式显示面板在弯曲时,基板与框胶间产生的应力导致薄膜部分剥离的状态示意图。 Stress flexible display panel [0029] More specifically, FIG. I (b) shown in FIG I (a) at the time of bending, between the substrate and the sealant produced results in substrate breakage state diagram of FIG. I (C) shows stress flexible display panel shown in FIG I (a) at the time of bending, between the substrate and the sealant film produced results in a schematic partial peeling state.

[0030] 参照图1(b),第一基板101和光学薄膜层103向上弯曲,此时,硬化后的框胶由于遭受较大的应力,其与第二基板201中的一部分基板201b、光学薄膜层203的一部分薄膜203b 一起向上运动。 [0030] Referring to FIG. 1 (b), the first substrate 101 and the optical film layer 103 is bent upward at this time, after the curing sealant by being subjected to greater stress, which is part of the substrate and the second substrate 201 is 201b, the optical together with the upward movement of the portion of the thin film layer 203 is 203b. 此时,第二基板201和光学薄膜层203会出现断裂情形,即,第二基板201的另一部分基板201a和光学薄膜层203的另一部分薄膜203a,与第二基板201的部分基板201b和光学薄膜层203的部分薄膜203b分割开来。 At this time, the second substrate 201 and the optical film layer 203 will break situation, i.e., the other portion of the substrate 201 of the second substrate 201a and the other portion of the film 203 of the optical film layer 203a, the second substrate portion 201 and the substrate 201b and the optical 203b film portion of the film layer 203 separated.

[0031] 参照图I (C),第一基板101和光学薄膜层103同样也向上弯曲,硬化后的框胶因遭受较大的应力,其与光学薄膜层203的一部分薄膜203b —起向上运动。 [0031] Referring to FIG I (C), the first substrate 101 and the optical film layer 103 is also bent upwardly, after curing sealant by subject to greater stress, which is a portion of the optical thin film layer 203 203b - from upward movement . 此时,该光学薄膜层203的其它部分薄膜203a与203c仍然位于第二基板201的上方。 At this time, the other portion of the optical thin film layers 203a and 203c are still 203 located above the second substrate 201. 如此一来,框胶30遭受的应力使得光学薄膜层203的部分薄膜出现剥离(peeling)情形,严重影响其光学性能,甚至会造成整个可挠性显示面板报废。 Thus, the sealant 30 is subjected to stress such that the optical film layer 203 portion of the film peeling occurs (Peeling) case, seriously affect its optical performance, or even cause the entire flexible display panel scrapped.

[0032] 为了有效地缓解或降低基板与框胶之间的应力所引起的上述困扰,图2示出依据本发明的一实施方式的可挠式显示面板的结构框图。 [0032] In order to effectively reduce or mitigate the above problems between the substrate and the stress caused by the sealant, Figure 2 shows a block diagram of the flexible display panel according to an embodiment of the present invention.

[0033] 参照图2,该可挠性显示面板包括一第一可挠性基板401、一第二可挠性基板403和一框胶405。 [0033] Referring to Figure 2, the flexible display panel comprises a first flexible substrate 401, a second flexible substrate 403 and a sealant 405. 其中,第二可挠性基板403位于第一可挠性基板401的下方,且与第一可挠性基板401相对设置。 Wherein the second flexible substrate 403 located below the first flexible substrate 401, and first flexible substrate 401 disposed opposite. 框胶405设置于第一可挠性基板401与第二可挠性基板403之间,作为该可挠性显示面板的封合件,用以粘合第一可挠式基板401与第二可挠式基板403。 The sealant 405 is provided on the first and the second flexible substrate 401 between the flexible substrate 403, as the flexible display panel seal member for bonding a first flexible substrate 401 and the second the flexible substrate 403. 例如,在该可挠性显示面板的截面上,整体呈框型结构的框胶405包括一胶合部405a和另一胶合部405b。 For example, in cross-section the flexible display panel, the overall shape of the sealant frame structure 405 includes a bonding portion 405a and the other gluing unit 405b. 需要指出的是,不同于现有技术中的框胶,本发明的框胶405由一弹性材料制成,该可挠性显示面板具有一曲率半径,且框胶405的杨氏模量(Young's modulus)的数值与该曲率半径的大小相对应,当可挠性基板401和403与框胶405之间出现压缩应力时,该框胶405可利用其自身材质的弹性形变来缓解或降低该压缩应力。 It is noted that, unlike the prior art the sealant, the sealant 405 of the present invention is made of a resilient material, the flexible display panel having a radius of curvature, and the Young's modulus of the sealant 405 (Young's Modulus) size values ​​corresponding to the radius of curvature, when the compression stress occurs between the sealant 401 and 403 and flexible substrate 405, the sealant 405 may utilize the elastic deformation of the material itself to reduce or mitigate the compression stress.

[0034] 在一具体实施例中,第一可挠性基板401和第二可挠性基板403由塑胶材料制成。 [0034] In one embodiment, the first flexible substrate 401 and second substrate 403 is made of a flexible plastic material.

[0035] 在一具体实施例中,框胶405的材质为聚甲基丙烯酸甲酯(acrylic)或环氧树脂(epoxy)ο例如,环氧树脂材质的框胶的杨氏模量介于IOOOMPa至IOOOOMPa之间。 [0035] In one embodiment, the sealant 405 is made of polymethyl methacrylate (Acrylic) or epoxy (epoxy) ο e.g., Young's modulus epoxy sealant material interposed IOOOMPa to between IOOOOMPa.

[0036] 此外,在上述图2中,当可挠性显示面板未发生弯曲时,框胶405的延伸方向与第一可挠性基板401相垂直,藉由胶框405、第一可挠性基板401和第二可挠性基板403构成一封闭空间,以容置一显示介质。 [0036] Further, in the above-described FIG. 2, when the flexible display panel is not bent, the sealant 405 and the extending direction of the first flexible substrate 401 perpendicularly, by a plastic frame 405, a first flexible substrate 401 and the second flexible substrate 403 constitute a closed space for accommodating a display medium. 例如,在该封闭空间中的显示介质包括液晶、电泳显示层或有机电致发光元件层。 For example, a display medium in the enclosed space comprises a liquid crystal, an electrophoretic display layer or the organic electroluminescent element layer.

[0037] 图3示出图2的可挠式显示面板在基板发生弯曲时,框胶材料的杨氏模量所对应的曲率半径的示意图。 [0037] Figure 3 shows a flexible display panel of Fig. 2 occurs when the substrate is bent, the radius of curvature schematic Young's modulus of the sealant material corresponds.

[0038] 参照图3,以第二可挠性基板403为例,当该第二可挠性基板403的最左侧和最右侧向下弯曲时,第二可挠性基板403和框胶405呈一圆弧形状。 [0038] Referring to FIG 3, a second flexible substrate 403 as an example, when the leftmost and rightmost bent downward the second flexible substrate 403, the second flexible substrate 403 and the sealant 405 form a circular arc shape. 在本发明中,为了达成藉由弹性材质的框胶来缓解基板与框胶间的应力的功效,可对应地设置可挠性显示面板的曲率半径与框胶的杨氏模量之间的数值关系。 In the present invention, by the sealant in order to achieve an elastic material to relieve stress between the substrate and the efficacy of the sealant, may be provided corresponding to the flexible display values ​​between the Young's modulus sealant with a radius of curvature of the panel relationship.

[0039] 更详细地,该可挠性显示面板(第一可挠性基板401或第二可挠性基板403)具有一曲率半径R,且框胶405的杨氏模量(Young's modulus )数值与曲率半径R的大小相对应。 [0039] In more detail, the flexible display panel (the first flexible substrate 401 or the second flexible substrate 403) having a radius of curvature R, the Young's modulus and the sealant 405 (Young's modulus) value R is the radius of curvature corresponding to the size. 当曲率半径大于IOOmm且小于200mm时,框胶405的杨氏模量介于2000MPa至3000MPa之间。 When the curvature radius IOOmm and less than 200mm, the Young's modulus of the sealant 405 interposed between 2000MPa to 3000MPa. 当曲率半径大于50mm且小于IOOmm时,框胶405的杨氏模量介于IOOOMPa至2000MPa之间。 When the radius of curvature is greater than 50mm and less than IOOmm, Young's modulus of the sealant 405 interposed between IOOOMPa to 2000MPa. 当曲率半径小于50mm时,框胶405的杨氏模量小于lOOOMPa。 When the radius of curvature of less than 50mm, the sealant 405 is less than the Young's modulus lOOOMPa. 由此可知,框胶405的杨氏模量的数值越大,可挠性显示面板的曲率半径越大,因而,可挠性显示面板的刚性越大。 It can be seen, the greater the value of the Young's modulus of the sealant 405, the larger the radius of curvature of the flexible display panel, therefore, the greater rigidity of the flexible display panel. 反之,框胶405的杨氏模量的数值越小,可挠性显示面板的曲率半径越小,因而,可挠性显示面板的挠性越大,进而基板与框胶间的应力相对更小。 Conversely, the value of the Young's modulus of the sealant 405, the smaller the radius of curvature of the flexible display panel, therefore, the greater the flexibility of the flexible display panel, and thus the stress between the substrate and the sealant relatively smaller .

[0040] 采用本发明的可挠性显示面板,在第一可挠性基板与第二可挠性基板之间设置一框胶,并且该框胶采用弹性材料制成,当可挠性显示面板中的可挠性元件出现弯曲时,藉由该弹性框胶材料可缓冲框胶与基板间的应力,改善可挠性元件的结构稳定性。 [0040] The present invention is a flexible display panel, a sealant disposed between the first flexible substrate and the second flexible substrate and the sealant is made of an elastic material, when the flexible display panel when the flexible element bowing, by the elastomeric sealant material may be a stress buffer between the sealant and the substrate, to improve the structural stability of the flexible element. [0041] 上文中,参照附图描述了本发明的具体实施方式。 [0041] In the above, the figures described specific embodiment of the present invention with reference to embodiments. 但是,本领域中的普通技术人员能够理解,在不偏离本发明的精神和范围的情况下,还可以对本发明的具体实施方式作各种变更和替换。 However, those skilled in the art will appreciate, without departing from the spirit and scope of the present invention, and various modifications may be made to the alternative embodiment of the present invention. 这些变更和替换都落在本发明权利要求书所限定的范围内。 These modifications and variations fall within the claims of the present invention as defined by the scope of the claims.
