请一并参阅图1及图2，图1是本申请第一实施例中的电子装置的立体结构示意图；图2是图1中的电子装置的柔性显示装置的立体结构示意图。本申请的第一实施例中的电子装置100包括壳体20及设置于壳体20上的柔性显示装置30。壳体20包括第一框体21、第二框体23及连接于第一框体21与第二框体23之间的弯折机构25。柔性显示装置30包括柔性屏32、设置于柔性屏32的背面的支撑层34及设置于支撑层34背离柔性屏32一侧的指纹识别模组36，支撑层34用于支撑指纹识别模组36，指纹识别模组36的感应信号能穿透支撑层34及柔性屏32。具体的，若所述指纹识别模组36是光学指纹识别模组，则柔性屏32及支撑层34的整体透光率满足光学指纹识别模组的需求；若所述指纹识别模组36是射频指纹识别模组，则柔性屏32及支撑层34的整体 信号穿透率满足射频指纹识别模组的需求。柔性屏32设置有对应弯折机构25的可折弯区域321及设置于可折弯区域31相对两侧的两个非折弯区域323，两个所述非折弯区域323分别连接于第一框体21及第二框体23的正面。指纹识别模组36设置于第一框体21与支撑层34之间或者第二框体23与支撑层34之间。本实施例中，指纹识别模组36设置于第二框体23与支撑层34之间，指纹识别模组36贴接于支撑层34的背面。
本实施例中，电子装置100为手机。可以理解，在其它实施例中，电子装置100可以是但不限于平板电脑、显示器、液晶面板、OLED面板、电视、智慧手表、车载显示器等其它任何具有显示触控功能的产品。本申请中的所述正面为与柔性屏32的出光面朝向相同的面，所述背面为与柔性屏32的出光面朝向相反的面。
本申请电子装置100的柔性显示装置30的柔性屏32的背面设置有支撑层34，指纹识别模组36设置于支撑层34背离柔性屏32的面，即指纹识别模组36设置于支撑层34的背面，支撑层34用于支撑指纹识别模组36。因此，指纹识别模组36没有直接贴合于柔性屏32的背面，而是通过支撑层34设置于柔性屏32的背面，柔性屏32对应指纹识别模组36的边缘不会出现应力集中问题，当柔性屏32的正面对应指纹识别模组36的位置收到按压时，柔性屏32对应指纹识别模组36的位置不会出现应力痕光影；其次，支撑层34对柔性屏32具有保护作用。可选地，支撑层34可具有一定的刚性，能起到支撑柔性屏32及指纹识别模组36的作用。另外，指纹识别模组36贴合于支撑层34的背面，支撑层34层叠于柔性屏32的背面，进而保证了指纹识别模组36与柔性屏32的平行度，提高了指纹识别模组36感应信号的收发精准性，增加了指纹采集效率及准确率，提高了用户体验。
请一并参阅图3至图5，图3是图2中的柔性显示装置的立体分解示意图；图4是图3中的柔性显示装置的另一视角立体示意图；图5是图2中沿V-V 线的剖视图。支撑层34包括透光区域，所述透光区域大于或等于指纹识别模组36与所述支撑层的贴合区域342，指纹识别模组36的感应信号能穿过所述透光区域。支撑层34除所述透光区域外的其他区域为非透光区域。本实施例中，支撑层34为透光的柔性玻璃片，所述柔性玻璃片的厚度为微米级，所述柔性玻璃片的正面或背面除贴合区域342外的其他区域全部覆盖非透光层。所述非透光层可以是贴合于柔性玻璃片的正面或背面的非透光膜，也可以是涂设于柔性玻璃片的正面或背面的非透光油墨，如黑色油墨等。所述柔性玻璃片除贴合区域342外的其他区域全部覆盖非透光层用于遮蔽背离柔性屏32的正面一侧的光线，提高柔性屏32显示时的对比度，增强柔性屏32的显示效果。当然，柔性玻璃片也可以通过其他方式来达成不透光的效果，比如在柔性玻璃片内避开透光区域的位置掺杂非透光颗粒，或者直接采用透光材料制作柔性玻璃片的透光区域，非透光材料制作柔性玻璃片的其他区域，再把二者接合成整体。
进一步的，支撑层34在柔性屏32的背面的正投影区域大于指纹识别模组36在柔性屏32的背面的正投影区域，且指纹识别模组36在柔性屏32的背面的正投影区域位于支撑层34在柔性屏32的背面的正投影区域内。
具体的，支撑层34可以贴合于柔性屏32的整个背面，即支撑层34在柔性屏32的背面的正投影区域与柔性屏32的背面重合，这种全覆盖的方式可以避免在支撑层34的相对两侧出现断差，防止柔性屏32出现褶皱或外观不良的情况。支撑层34也可以仅贴合于柔性屏32的部分背面，如仅贴合于柔性屏32正对第一框体21或第二框体23的背面，即支撑层34在柔性屏32的背面的正投影区域与柔性屏32正对第一框体21或第二框体23的背面区域重合，指纹识别模组36设置于第一框体21与支撑层34之间或者指纹识别模组36设置于第二框体23与支撑层34之间，这种部分覆盖的方式可以节省制造成本。本实施例中，支撑层34贴合于柔性屏32的整个背面。
指纹识别模组36包括面朝贴合区域342的信号收发面360，指纹识别模 组36电性连接于电子装置100的主板。使用指纹识别模组36时，指纹识别模组36通过信号收发面360向用户手指发出感应信号，所述感应信号穿过支撑层34的贴合区域342及柔性屏32到达用户手指，所述感应信号被用户手指反射后向信号收发面360反馈感应信号，信号收发面360接收从用户指纹反射回的指纹信号，并通过与发出的感应信号作比较，以检测出用户指纹信息。在一实施例中，所述指纹识别模组36是光学指纹识别模组，贴合区域342是透光区域，因此，指纹识别模组36的感应信号能穿过支撑层34及柔性屏32，从而保证了信号收发面360在发出感应信号后可以有效接收到感应信号。在其他实施例中，支撑层34包括透光区域，所述透光区域大于或等于指纹识别模组36与支撑层34的贴合区域342，指纹识别模组36的感应信号穿过所述透光区域。
在其他实施例中，指纹识别模组36也可以是射频指纹识别模组，至少位于所述贴合区域342范围内的柔性屏32及支撑层34的整体信号穿透率满足射频指纹识别模组的需求。优选的，柔性屏32及支撑层34对应于所述贴合区域342的部分或整体由减少信号损耗的材料制成。
本实施例中，支撑层34为柔性玻璃片。柔性玻璃片具有较好的耐弯折性、高强度、高硬度等优点，对指纹识别模组36具有良好的支撑作用；其次，柔性玻璃片的弹性模量较低，在柔性显示装置30弯曲时可跟随柔性屏32一起同步或近似同步拉伸，从而避免柔性显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况。另外，所述柔性玻璃片的透光率高，方便指纹识别模组36的感应信号的穿透。
优选地，支撑层34的厚度范围为5微米至80微米之间(含本数)。
在其他实施例中，支撑层34由透光的高分子聚合材料制成，具体的，支撑层34也可以是其他透明板，比如透明的聚碳酸酯片、亚克力板或PT等高分子聚合材料。
支撑层34与柔性屏32之间还可设置胶体层，所述胶体层粘接支撑层34与柔性屏32。进一步的，所述胶体层为透光胶体层35，即支撑层34的正面通过透光胶体层35贴接于柔性屏32的背面。具体的，透光胶体层35可以是透光的光学胶体或光学胶水。
请参阅图6，图6是本申请第二实施例中的电子装置的柔性显示装置的部分剖视结构示意图。本申请的电子装置的第二实施例的结构与第一实施例的结构相似，不同之处在于：
在第二实施例中，柔性显示装置30a还包括定位件37，定位件37包括定位框370及设置于定位框370周围的连接片375，定位框370设置用于收纳指纹识别模组36的收纳槽372，收纳槽372的开口朝向支撑层34的背面，连接片375贴接支撑层34的背面，以定位指纹识别模组36于支撑层34的背面。优选的，连接片375与定位框370一体成型。
具体的，定位框370包括底板371及设置于底板371周围的围板373，底板371与围板373共同围成收纳槽372。连接片375自围板373远离底板371的一侧沿垂直于收纳槽372的开口朝向延伸。连接片375可以是设置于围板373周围的环形片，连接片375也可以是设置于围板373相对的两侧的板体。本实施例中，底板371是矩形板，围板373是围设于底板371边缘的矩形板体，连接片375背离底板371的侧面与围板373背离底板371的侧面齐平，即连接片375的正面与围板373的侧面共面。指纹识别模组36收纳于收纳槽372内时，指纹识别模组36的信号收发面360与连接片375的正面齐平。
本实施例中，指纹识别模组36通过定位框370定位于支撑层34的背面，具体的，指纹识别模组36的信号收发面360贴合于支撑层34背面的贴合区域342，连接片375粘贴于支撑层34的背面于贴合区域342的周围，以定位指纹识别模组36。由于指纹识别模组36通过定位件37固定于支撑层34的背面，指纹识别模组36没有直接粘接于柔性屏32的背面，因此，柔性屏32对应指 纹识别模组36的边缘不会出现应力集中，以防止柔性屏32出现应力痕光影。另外，通过连接片375贴合于支撑层34的背面，从而拓宽了指纹识别模组36与支撑层34的贴合面积，并且连接片375与指纹识别模组36的信号收发面360相平行，支撑层34层叠于柔性屏32的背面，进而保证了信号收发面360与柔性屏32的平行度，提高了指纹识别模组36感应信号的收发精准性，增加了指纹采集效率及准确率，提高了用户体验。
请参阅图7，图7是本申请第三实施例中的电子装置的柔性显示装置的部分剖视结构示意图。本申请的电子装置的第三实施例的结构与第二实施例的结构相似，不同之处在于：支撑层34开设对应收纳槽372的通孔344，指纹识别模组36部分收纳于所述通孔344内且信号收发面360与支撑层34的正面共面，信号收发面360与支撑层34的正面之间隙。
在本实施例中，支撑层34可以是透光的支撑片，如柔性玻璃片、聚碳酸酯片、亚克力板等高分子聚合材料；支撑层34也可以是液态金属片、薄钢片、记忆合金、塑胶片或橡胶片等，只需这些片体具有耐弯折性和具有一定硬度即可。更优选的支撑层34采用液态金属片，所述液态金属片可以为铜、钛、铁、锆、银、镍、镓、金、锑、镉、锌、铟、硅等中一种或多种材料的合金材料，具体金属优选可获得更低的弹性模量、硬度、延伸性等其他力学性质。
所述液态金属是指将合金加热到熔融态，然后以超快的冷却速度冷却，使合金晶格来不及有序排列结晶便固化，因为是非结晶状态，像玻璃，所以又被称为非晶合金、液态金属或金属玻璃。液态金属的特性是长程无序(短程有序)、亚稳态、一定程度上的物理特性各向同性、没有确切熔点、具有玻璃转化温度点等，具有固态、金属、玻璃的特性，可以在一定条件下具有高强度、高硬度、塑性、热传导和耐磨性等。
本实施例中,支撑层34为液态金属保护层，所述液态金属保护层的厚度为5微米至200微米(含本数)。所述液态金属保护层可以覆盖柔性屏32的整个背 面或部分背面。
本实施例中选用液态金属片作为支撑层34的原因在于液态金属片的耐磨性较佳，当其通过透光胶体层35贴设于柔性屏32的背面时，不仅可以支撑所述柔性屏32及指纹识别模组36，并且可以有效地抵御弯折机构25对其产生的摩擦，不易出现磨损的情况。另一方面，液态金属片的弹性模量相比于常见的金属(如钢片、铝片、铁片等)较低，可将其直接粘贴在柔性屏32的背面，在柔性显示装置30弯曲时可跟随柔性屏32一起同步或近似同步拉伸，从而避免柔性显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况。并且，相比于现有的弹性模量更低的材料，如硅胶、泡棉、塑胶等，液态金属的强度更高，可有效地对柔性屏32及指纹识别模组36进行支撑。
本实施例中，指纹识别模组36通过定位框370定位于支撑层34的背面，指纹识别模组36的信号收发面360与支撑层34的正面共面，且信号收发面360与支撑层34的正面之间隙。因此，信号收发面360与支撑层34的正面的平整性好，柔性屏32对应指纹识别模组36的边缘不会出现应力集中，以防止柔性屏32出现应力痕光影；其次，通过连接片375贴合于支撑层34的背面，从而连接片375与指纹识别模组36的信号收发面360相平行，支撑层34层叠于柔性屏32的背面，进而保证了信号收发面360与柔性屏32的平行度，提高了指纹识别模组36感应信号的收发精准性；另外，信号收发面360至柔性屏32的正面的距离相较于第二实施例减小，即信号收发面360至用户指纹的距离减小，使指纹识别模组36的感应信号的收发距离减小，从而能提高指纹识别模组36的信号收发效率。
在其他实施例中，支撑层34的通孔344可以填充透光的刚性材料层，所述刚性材料层的正面与支撑层34的正面共面，且所述刚性材料层的正面与支撑层34的正面之间无间隙。
请参阅图8，图8是本申请第四实施例中的电子装置的柔性显示装置的部 分剖视结构示意图。本申请的电子装置的第四实施例的结构与第三实施例的结构相似，不同之处在于：定位框370开设穿线孔376。
本实施例中的柔性显示装置30d的支撑层34也开设对应收纳槽372的通孔344，指纹识别模组36设置有信号收发面360的一侧收纳于通孔344内。进一步的，信号收发面360与支撑层34面朝柔性屏32的出光面的面齐平，即信号收发面360与支撑层34的正面齐平。
定位框370的底板371开设穿线孔376，线缆穿设于穿线孔376，线缆的两端分别电性连接于指纹识别模组36及电子装置的主板，指纹识别模组36将采集到的用户指纹发送至所述主板。
本申请提供的显示装置30的柔性屏32的背面设置有支撑层34，指纹识别模组36直接或通过定位件37设置于支撑层34的背面。因此，指纹识别模组36没有直接贴合于柔性屏32的背面，柔性屏32对应指纹识别模组36的边缘不会出现应力集中，以防止柔性屏32出现应力痕光影；其次，支撑层34还具有刚性，对柔性屏32及指纹识别模组36具有支撑作用。
在其他实施例中，柔性屏32的正面还覆盖有透光的、具有柔性且能弯曲的薄片，所述薄片为柔性玻璃片，所述柔性玻璃片的厚度为微米级。所述柔性玻璃片不仅可以随所述柔性屏32弯曲或展平，并且可以有效地抵御外部物件对柔性玻璃片划伤，不易出现磨损的情况。其次，柔性玻璃片的弹性模量较低，可将其直接粘贴在柔性屏32的正面，在柔性显示装置30弯曲时可跟随柔性屏32一起同步或近似同步拉伸，从而避免柔性显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况；另外，所述柔性玻璃片的透光率高，方便所述柔性屏32的光线的射出，且长时间使用后，所述柔性玻璃片也不会出现变色等问题。
请参阅图9，图9是本申请第五实施例中的电子装置的柔性显示装置的部分剖视结构示意图。本申请的电子装置的第五实施例的结构与第一实施例的结 构相似，不同之处在于：支撑板34背离柔性屏32的一侧设置透光层38，指纹识别模组36设置于透光层38背离柔性屏32的一侧，即透光层38层叠于支撑板34的背面。具体的，透光层38通过透光胶体层35贴设于支撑板34的背面，指纹识别模组36贴设于透光层38的背面。
透光层38可以是但不限于透明的亚克力板或透明玻璃等。
进一步的，透光层38除对应指纹识别模组36的信号收发面360外的其他区域为非透光区域。本实施例中，透光层38的正面或背面除对应信号收发面360外的其他区域全部覆盖非透光层。所述非透光层可以是贴合于透光层38的正面或背面的非透光膜，也可以是涂设于透光层38的正面或背面的非透光油墨，如黑色油墨等。所述透光层38除对应信号收发面360外的其他区域全部覆盖非透光层用于遮蔽背离柔性屏32的正面一侧的光线，提高柔性屏32显示时的对比度，增强柔性屏32的显示效果。
本实施例中，在柔性屏32的背面贴设支撑层34，再在支撑层34的背面贴设透光层38，指纹识别模组36设置于透光层38背离柔性屏32的面，支撑层及透光层38均对指纹识别模组36具有支撑作用，柔性屏32对应指纹识别模组36的边缘不会出现应力集中问题，当柔性屏32的正面对应指纹识别模组36的位置收到按压时，柔性屏32对应指纹识别模组36的位置不会出现应力痕光影；另外，指纹识别模组36贴合于透光层38的背面，透光层38层叠于支撑层34的背面，支撑层34层叠于柔性屏32的背面，更进一步保证了指纹识别模组36与柔性屏32的平行度，提高了指纹识别模组36感应信号的收发精准性，增加了指纹采集效率及准确率，提高了用户体验。
以上所述是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
