本发明是关于一种电子装置。The invention relates to an electronic device.

背景技术Background technique

软性显示器比传统显示器更轻、更薄而便于携带。例如，可通过卷轴卷绕软性显示器于其上来携带软性显示器。传统将软性显示器固定于卷轴的方法为胶带固定法。然而，在卷绕软性显示器时，会因软性显示器的堆叠结构与胶带所产生的台阶现象，使软性显示器在卷绕数圈后，应力集中于部分的软性显示器，导致显示画面损伤，甚至软性显示器上的电路亦受应力挤压而受损失效。Flexible displays are lighter, thinner and portable than conventional displays. For example, the flexible display may be carried by winding the flexible display on a reel. The traditional method of fixing the flexible display on the reel is the tape fixing method. However, when winding the flexible display, due to the step phenomenon produced by the stacked structure of the flexible display and the adhesive tape, after the flexible display is wound several times, the stress will concentrate on part of the flexible display, resulting in damage to the display screen , Even the circuit on the flexible display is damaged and fails due to stress extrusion.

此外，软性显示器的堆叠结构在经过多次卷绕后，压应力与拉伸应力分别集中于软性显示器的内部与外部，且因为软性显示器在卷绕后会产生内径周长与外径周长的差异，导致软性显示器的堆叠结构存在脱层问题，尤其是软性显示器的越末端处容易发生越严重的膜层错位现象。In addition, after multiple windings of the stacked structure of the flexible display, the compressive stress and the tensile stress are respectively concentrated on the inside and outside of the flexible display, and because the flexible display will have inner diameter perimeter and outer diameter after winding The difference in perimeter leads to delamination in the stacked structure of the flexible display, especially at the end of the flexible display, the more serious film misalignment tends to occur.

以下将以附图公开本发明的多个实施方式，为明确说明，许多实务上的细节将在以下叙述中一并说明。然而，应了解到，这些实务上的细节不应用以限制本发明。也就是说，在本发明部分实施方式中，这些实务上的细节是非必要的。此外，为简化附图起见，一些公知惯用的结构与元件在附图中将以简单示意的方式绘示。A number of embodiments of the present invention will be disclosed below with drawings, and many practical details will be described together in the following description for clarity. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some well-known and commonly used structures and elements will be shown in a simple and schematic manner in the drawings.

图1A绘示根据本发明的一实施例的电子装置10的剖面图。图1B为图1A的区域R的放大示意图。请同时参照图1A及图1B。电子装置10包括可挠式显示器100以及卷轴102。可挠式显示器100具有本体部B及端部E，可挠式显示器100的端部E固定于卷轴102。卷轴102用以卷绕或展开可挠式显示器100。可挠式显示器100包括驱动基板104、显示层106、前保护层108及后保护层110。显示层106位于驱动基板104上，前保护层108覆盖显示层106，并通过胶层112贴附于驱动基板104的顶面104a。后保护层110位于驱动基板104的底面，并通过胶层114贴附于驱动基板104。前保护层108及后保护层110可用于防止水气渗入及紫外线进入显示层106及驱动基板104。在本实施例中，前保护层108的材质可以包括有机材料。FIG. 1A is a cross-sectional view of anelectronic device 10 according to an embodiment of the invention. FIG. 1B is an enlarged schematic view of a region R in FIG. 1A . Please refer to FIG. 1A and FIG. 1B at the same time. Theelectronic device 10 includes aflexible display 100 and ascroll 102 . Theflexible display 100 has a body part B and an end part E, and the end part E of theflexible display 100 is fixed on thescroll 102 . The rollingshaft 102 is used for winding or unrolling theflexible display 100 . Theflexible display 100 includes a drivingsubstrate 104 , adisplay layer 106 , afront protection layer 108 and arear protection layer 110 . Thedisplay layer 106 is located on the drivingsubstrate 104 , and the frontprotective layer 108 covers thedisplay layer 106 and is attached to thetop surface 104 a of the drivingsubstrate 104 through theadhesive layer 112 . Therear protection layer 110 is located on the bottom surface of the drivingsubstrate 104 and attached to the drivingsubstrate 104 through theadhesive layer 114 . Thefront protection layer 108 and therear protection layer 110 can be used to prevent water vapor from infiltrating and ultraviolet rays from entering thedisplay layer 106 and the drivingsubstrate 104 . In this embodiment, the material of thefront protection layer 108 may include organic materials.

驱动基板104例如是主动元件阵列基板，但本发明不以此为限。具体来说，驱动基板104例如是由具有可挠性的塑胶或金属的材料所构成的薄膜驱动基板，使电子装置10更轻薄且便于携带。在本实施例中，显示层106可为电泳显示层。The drivingsubstrate 104 is, for example, an active device array substrate, but the present invention is not limited thereto. Specifically, the drivingsubstrate 104 is, for example, a thin-film driving substrate made of flexible plastic or metal material, which makes theelectronic device 10 thinner and more portable. In this embodiment, thedisplay layer 106 may be an electrophoretic display layer.

在本实施例中，卷轴102包括固定槽116。固定槽116凹设于卷轴102的外表面102a，并用以固定可挠式显示器100于卷轴102。可挠式显示器100的端部E位于固定槽116中。在本实施例中可挠式显示器100的端部E的厚度T1小于本体部B的厚度(例如本体部B的最小厚度T2)(见图1B)，前保护层108的长度小于驱动基板104的长度，前保护层108不延伸至可挠式显示器100的端部E，换言之，前保护层108位于卷轴102的固定槽116外，如此一来，可挠式显示器100被卷轴102卷绕后的内径与外径之间的圆周长差值被降低，从而减少应力集中于可挠式显示器100的端部E，也避免了可挠式显示器100的膜层错位的问题。In this embodiment, thespool 102 includes a retainingslot 116 . The fixinggroove 116 is recessed on theouter surface 102 a of thescroll 102 and used for fixing theflexible display 100 on thescroll 102 . The end E of theflexible display 100 is located in the fixinggroove 116 . In this embodiment, the thickness T1 of the end portion E of theflexible display 100 is smaller than the thickness of the body portion B (for example, the minimum thickness T2 of the body portion B) (see FIG. 1B ), and the length of the frontprotective layer 108 is shorter than that of the drivingsubstrate 104. Length, the frontprotective layer 108 does not extend to the end E of theflexible display 100, in other words, the frontprotective layer 108 is located outside the fixinggroove 116 of thereel 102, so that the The difference in the circumference length between the inner diameter and the outer diameter is reduced, thereby reducing the stress concentration on the end E of theflexible display 100 and avoiding the misalignment of the film layers of theflexible display 100 .

此外，卷轴102还具有容置槽118与伸缩组件120。容置槽118凹设于卷轴102的外表面102a，且最靠近固定槽116的容置槽118与固定槽116彼此相隔距离S。伸缩组件120设置于容置槽118中，当卷轴102开始卷绕可挠式显示器100时，伸缩组件120可接触可挠式显示器100。在本实施例中，当伸缩组件120抵靠可挠式显示器100时，伸缩组件120可被压入容置槽118。在卷绕可挠式显示器100时，通过伸缩组件120朝卷轴102的圆心C方向溃缩，可避免可挠式显示器100在卷绕过程中产生应力集中，也避免了可挠式显示器100的膜层错位的问题。In addition, thereel 102 also has anaccommodating slot 118 and atelescoping assembly 120 . Theaccommodating slots 118 are recessed on theouter surface 102 a of thereel 102 , and theaccommodating slots 118 closest to the fixingslots 116 and the fixingslots 116 are separated by a distance S from each other. Thetelescoping component 120 is disposed in theaccommodating groove 118 , and when thereel 102 starts to wind theflexible display 100 , thetelescoping component 120 can contact theflexible display 100 . In this embodiment, when thetelescopic assembly 120 abuts against theflexible display 100 , thetelescopic assembly 120 can be pressed into the receivinggroove 118 . When theflexible display 100 is wound, theretractable assembly 120 collapses toward the center C of thereel 102, thereby avoiding the stress concentration of theflexible display 100 during the winding process, and also avoiding the damage of the film of theflexible display 100. layer misalignment problem.

在本实施例中，伸缩组件120包括弹性件122及活动件124，弹性件122位于活动件124与卷轴102的圆心C之间。弹性件122的第一端122a位于容置槽118的底壁118a。活动件124位于弹性件122远离第一端122a的第二端122b上，用以抵靠可挠式显示器100。在可挠式显示器100被卷轴102卷绕的过程中，活动件124可抵靠可挠式显示器100，因此活动件124被压入容置槽118，也就是活动件124朝着卷轴102的圆心C移动，进而使得弹性件122朝卷轴102的圆心C被压缩。换言之，利用弹性件122产生弹性形变，弹性件122及活动件124可溃缩并吸收可挠式显示器100在卷绕过程中所产生的应力。在本实施例中，弹性件122可以为弹簧，但并不用以限制本发明，其他可伸缩的弹性材料也可作为弹性件122。In this embodiment, thetelescoping assembly 120 includes anelastic member 122 and amovable member 124 , and theelastic member 122 is located between themovable member 124 and the center C of thereel 102 . Thefirst end 122 a of theelastic member 122 is located on thebottom wall 118 a of the receivinggroove 118 . Themovable part 124 is located on thesecond end 122 b of theelastic part 122 away from thefirst end 122 a for abutting against theflexible display 100 . When theflexible display 100 is wound by thereel 102 , themovable part 124 can abut against theflexible display 100 , so themovable part 124 is pressed into theaccommodating groove 118 , that is, themovable part 124 faces the center of the reel 102 C moves, and then theelastic member 122 is compressed toward the center C of thereel 102 . In other words, theelastic member 122 produces elastic deformation, theelastic member 122 and themovable member 124 can collapse and absorb the stress generated during the winding process of theflexible display 100 . In this embodiment, theelastic member 122 can be a spring, but this is not intended to limit the invention, and other stretchable elastic materials can also be used as theelastic member 122 .

在本实施例中，活动件124具有背对弹性件122的弹性面124a，使活动件124的外表面有弹性而进一步提高了伸缩组件120的溃缩效果。此外，活动件124的弹性面124a与侧壁124b的连接处形成导圆角(round-corner)124c，可避免可挠式显示器100的端部E因为被弯折而断裂。In this embodiment, themovable member 124 has anelastic surface 124 a facing away from theelastic member 122 , which makes the outer surface of themovable member 124 elastic and further improves the collapse effect of thetelescopic assembly 120 . In addition, a round-corner 124c is formed at the junction of theelastic surface 124a of themovable member 124 and theside wall 124b, which can prevent the end E of theflexible display 100 from being broken due to being bent.

固定槽116具有内壁116a，卷轴102邻接内壁116a的外表面102a处具有导圆角102b。当可挠式显示器100被弯折时，接触导圆角102b的可挠式显示器100的端部E可受力均匀，因此避免了因应力过度集中于可挠式显示器100的端部E而使其断裂的风险。The fixinggroove 116 has aninner wall 116a, and theouter surface 102a of thereel 102 adjacent to theinner wall 116a has afillet 102b. When theflexible display 100 is bent, the end E of theflexible display 100 contacting therounded corner 102b can be evenly stressed, thus avoiding excessive stress concentration on the end E of theflexible display 100 risk of its breakage.

在一实施例中，伸缩组件120的数量为多个，且伸缩组件120相对于卷轴102的圆心C呈对称排列。如此一来，在卷绕的过程中，可进一步降低应力集中于可挠式显示器100。In one embodiment, there are multipletelescopic assemblies 120 , and thetelescopic assemblies 120 are symmetrically arranged with respect to the center C of thereel 102 . In this way, during the winding process, the stress concentration on theflexible display 100 can be further reduced.

图2A绘示根据本发明的一实施例的电子装置20的剖面图。请参照图2A，电子装置20包括可挠式显示器100、卷轴102及粘着层126。粘着层126位于可挠式显示器100的端部E与卷轴102之间，以固定可挠式显示器100于卷轴102。FIG. 2A is a cross-sectional view of an electronic device 20 according to an embodiment of the present invention. Please refer to FIG. 2A , the electronic device 20 includes aflexible display 100 , ascroll 102 and anadhesive layer 126 . Theadhesive layer 126 is located between the end E of theflexible display 100 and theroll 102 to fix theflexible display 100 on theroll 102 .

在本实施例中，卷轴102具有至少一个凹部102r，粘着层126位于可挠式显示器100的端部E与卷轴102的凹部102r之间，这样的配置可减少卷绕时的应力集中于可挠式显示器100的端部E。粘着层126具有相对的顶面126a与底面126b，粘着层126的顶面126a接触卷轴102的凹部102r。如此一来，即使卷绕后的可挠式显示器100因内径与外径之间的圆周长差异而产生应力，此应力也不会集中于可挠式显示器100在卷轴102的固定处。换言之，可降低应力集中于可挠式显示器100的端部E，也降低可挠式显示器100的膜层错位的风险。在本实施例中，由于可挠式显示器100的端部E的厚度T1小于本体部B的厚度(例如本体部B的最小厚度T2)，前保护层108的长度小于驱动基板104的长度，前保护层108不延伸至可挠式显示器100的端部E，端部E如此一来，可挠式显示器100被卷轴102卷绕后的内径的圆周长与外径的圆周长之间的差值被降低，从而减少应力集中于可挠式显示器100的端部E，也避免了可挠式显示器100的膜层错位的问题。In this embodiment, thereel 102 has at least onerecess 102r, and theadhesive layer 126 is located between the end E of theflexible display 100 and therecess 102r of thereel 102. The end E of thetype display 100 . Theadhesive layer 126 has atop surface 126 a and abottom surface 126 b opposite to each other, and thetop surface 126 a of theadhesive layer 126 contacts theconcave portion 102 r of thereel 102 . In this way, even if the rolledflexible display 100 generates stress due to the difference in the circumference between the inner diameter and the outer diameter, the stress will not concentrate on the fixed position of theflexible display 100 on theroll 102 . In other words, the stress concentration on the end E of theflexible display 100 can be reduced, and the risk of misalignment of the film layers of theflexible display 100 can also be reduced. In this embodiment, since the thickness T1 of the end part E of theflexible display 100 is smaller than the thickness of the body part B (for example, the minimum thickness T2 of the body part B), the length of the frontprotective layer 108 is smaller than the length of the drivingsubstrate 104, and the front Theprotective layer 108 does not extend to the end E of theflexible display 100. In this way, the difference between the circumference length of the inner diameter and the circumference length of the outer diameter of theflexible display 100 after being wound by thereel 102 is reduced, thereby reducing stress concentration on the end E of theflexible display 100 and also avoiding the problem of dislocation of the film layers of theflexible display 100 .

当卷轴102开始卷绕可挠式显示器100时，凹部102r接触可挠式显示器100，因此可避免应力集中于可挠式显示器100，减少应力集中于可挠式显示器100的端部E。在一实施例中，凹部102r的数量为多个，凹部102r相对于卷轴102的圆心C呈对称排列，如此一来，在卷绕的过程中，可进一步降低应力集中于可挠式显示器100。When thereel 102 starts to wind theflexible display 100 , theconcave portion 102 r contacts theflexible display 100 , thus avoiding stress concentration on theflexible display 100 and reducing stress concentration on the end E of theflexible display 100 . In one embodiment, there aremultiple recesses 102r, and therecesses 102r are arranged symmetrically with respect to the center C of thereel 102, so that stress concentration on theflexible display 100 can be further reduced during the winding process.

The difference between theelectronic device 30 of this embodiment and the electronic device 20 in FIG. 2A is that thereel 102 further includes atelescopic component 220 .Telescoping assembly 220 is similar totelescoping assembly 120 of FIG. 1A . Thetelescoping assembly 220 includes an elastic member 222 and amovable member 224. The elastic member 222 is located between themovable member 224 and the center C of thereel 102. Themovable member 224 has anelastic surface 224a facing away from the elastic member 222, so that themovable member 224 has elastic ability and The collapse effect of thetelescopic assembly 220 is further improved. The rest of the details of thetelescoping component 220 will not be repeated here. In this embodiment, thetelescopic assembly 220 is adjacent to theconcave portion 102r, and thetelescopic assembly 220 can contact theflexible display 100 during the process of theflexible display 100 being wound up by thereel 102 . When thetelescopic assembly 220 abuts against theflexible display 100, thetelescopic assembly 220 is pressed into theaccommodating groove 218, and the elastic member 222 is used to produce elastic deformation, and the elastic member 222 and themovable member 224 can collapse and absorb theflexible display 100. Stress generated during winding.

在一实施例中，伸缩组件220的数量为多个，伸缩组件220相对于卷轴102的圆心C呈对称排列。凹部102r的数量为多个，凹部102r相对于卷轴102的圆心C呈对称排列。举例而言，凹部102r与伸缩组件220呈间隔排列。在可挠式显示器100被卷轴102卷绕的过程中，伸缩组件220可先接触可挠式显示器100。当伸缩组件220抵靠可挠式显示器100时，伸缩组件220被压入容置槽118，利用弹性件222产生弹性形变，弹性件222及活动件224可溃缩并吸收可挠式显示器100在卷绕过程中所产生的应力。接着，凹部102r抵靠可挠式显示器100，因此可避免应力集中于可挠式显示器100，有效地降低可挠式显示器100因应力导致的膜层错位的风险。In one embodiment, there are multipletelescopic assemblies 220 , and thetelescopic assemblies 220 are arranged symmetrically with respect to the center C of the circle of thereel 102 . There aremultiple recesses 102 r , and therecesses 102 r are arranged symmetrically with respect to the center C of the circle of thereel 102 . For example, theconcave portion 102r and thetelescopic component 220 are arranged at intervals. During the process of theflexible display 100 being wound by thereel 102 , thetelescoping component 220 may contact theflexible display 100 first. When thetelescopic assembly 220 abuts against theflexible display 100, thetelescopic assembly 220 is pressed into theaccommodating groove 118, and the elastic member 222 is used to produce elastic deformation. Stress generated during winding. Next, theconcave portion 102r abuts against theflexible display 100 , thus avoiding the concentration of stress on theflexible display 100 , effectively reducing the risk of misalignment of the film layers of theflexible display 100 caused by stress.

图3绘示根据本发明的另一实施例的电子装置40的剖面图。本实施例的电子装置40与图2A的电子装置20的差异在于：电子装置40可以有粘着层126或省略粘着层126，且卷轴102包括固定槽216。固定槽216类似于图1A的固定槽116，因此固定槽216的细节于此不再赘述。在本实施例中，固定槽216位于凹部102r中，如此一来，在卷绕的过程中，可避免应力集中于可挠式显示器100的端部E，也避免可挠式显示器100的膜层错位的风险。FIG. 3 is a cross-sectional view of anelectronic device 40 according to another embodiment of the present invention. The difference between theelectronic device 40 of this embodiment and the electronic device 20 of FIG. 2A is that: theelectronic device 40 may have theadhesive layer 126 or omit theadhesive layer 126 , and thereel 102 includes the fixinggroove 216 . The fixingslot 216 is similar to the fixingslot 116 in FIG. 1A , so the details of the fixingslot 216 will not be repeated here. In this embodiment, the fixinggroove 216 is located in theconcave portion 102r.

综上所述，本发明的实施例的电子装置中，通过使用具有固定槽的卷轴，可降低应力集中于可挠式显示器的端部，且由于可挠式显示器的端部的厚度小于本体部的厚度，可挠式显示器被卷轴卷绕后的内径与外径之间的圆周长差值被降低，从而减少应力集中于可挠式显示器的端部，也避免可挠式显示器的膜层错位。卷轴还具有设置于容置槽中的伸缩组件，当伸缩组件抵靠可挠式显示器时，伸缩组件被压入容置槽。通过使用具有伸缩组件的卷轴，在卷绕可挠式显示器时，通过伸缩组件朝卷轴的圆心方向溃缩，可避免可挠式显示器在卷绕过程中产生应力集中，也避免了可挠式显示器的膜层错位的问题。伸缩组件还包括活动件与弹性件。活动件具有背对弹性件的弹性面，且弹性面与活动件的一侧壁的连接处形成导圆角，可避免位于固定槽的可挠式显示器的端部因为被弯折而断裂。卷轴邻接内壁的外表面处具有导圆角。当可挠式显示器被弯折时，接触导圆角的可挠式显示器可受力均匀，因此避免了因应力过度集中于可挠式显示器的端部而使其断裂的风险。To sum up, in the electronic device of the embodiment of the present invention, by using the reel with the fixing groove, the stress concentration on the end of the flexible display can be reduced, and since the thickness of the end of the flexible display is smaller than that of the main body The thickness, the circumference difference between the inner diameter and the outer diameter of the flexible display after being wound by the reel is reduced, thereby reducing the stress concentration on the end of the flexible display and avoiding the misalignment of the film layer of the flexible display . The reel also has a telescopic assembly arranged in the accommodation groove, and when the telescopic assembly abuts against the flexible display, the telescopic assembly is pressed into the accommodation groove. By using a reel with a telescopic component, when the flexible display is wound, the telescopic component collapses toward the center of the reel, thereby avoiding stress concentration of the flexible display during the winding process, and also avoiding the The problem of misalignment of the film layer. The telescopic assembly also includes movable parts and elastic parts. The movable part has an elastic surface facing away from the elastic part, and the connection between the elastic surface and the side wall of the movable part forms a fillet, which can prevent the end of the flexible display located in the fixing groove from being broken due to being bent. The outer surface of the spool adjoining the inner wall has a fillet. When the flexible display is bent, the flexible display contacting the rounded corners can be evenly stressed, thus avoiding the risk of breaking the flexible display due to excessive stress concentrated on the end of the flexible display.
