 本发明的最佳实施方式
在此处键入本发明的最佳实施方式描述段落。
 本发明的实施方式
为详细说明本发明的技术内容、所实现目的及效果，以下结合实施方式并配合附图予以说明。
需要说明，本发明中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
请参照图1及图2，在本发明实施例中，该柔性LED显示屏由多块LED单元屏10拼接而成，相邻LED单元屏10通过显示屏的连接结构拼接形成整体显示屏。具体的，相邻LED单元屏10的拼接包括上下拼接和/或左右拼接。具体的拼接结构可根据实际的要求来设置，如单排呈横向分布的显示屏、单列呈竖向分布的显示屏或呈阵列状的显示屏。
考虑到相邻LED单元屏10拼接时容易出现棱角或棱边导致整体显示屏的平滑度较差，影响整体显示效果的问题，本方案提出了一种柔性显示屏，包括若干块底壳100；连接片200，其设置在底壳100上且将若干块底壳100串接；PCB灯板300，其设置在底壳100上且若干块的底壳100与PCB灯板300匹配安装；连接器400，其包括与连接片200搭接的第一伸出部413，连接器400位于外缘处的底壳100上；电源板结构500，其包括与连接片200搭接的第二伸出部，电源板结构500位于底壳100的中部位置。多个间隔的底壳100经连接片200连接拼装形成一个LED单元屏10，多个LED单元屏10可以形成显示屏幕墙。相邻底壳100之间可以转动一定角度，如此，LED单元屏10可以沿着底壳100的拼装方向弯曲，能够提高显示屏幕墙的弯折度。
在一种实施例中，若干块的底壳100与同一PCB灯板300匹配安装，具体的为一整块的PCB灯板300上同时设置有多块依次间隔设置的底壳100，从而使PCB灯板300固定在底壳100上，由于PCB灯板300整体轻薄不占空间，这样使LED单元屏10的整体性更好更轻薄。
在另一种实施例中，若干块的底壳100中每一个底壳100上分别对应设有一个PCB灯板300，相邻的PCB灯板300之间用软排线电信号连接，这样可以避免采用同一块PCB灯板300上设置多个底壳100的情况下，PCB灯板300在相邻底壳100间隙的外露部分受力后容易断裂的问题产生，即PCB灯板300在相邻底壳100间隙的外漏部分由软排线替代，软排线的连端与PCB灯板300固定连接。
可以理解的是，第一伸出部具体为第一导电片413，第二伸出部具体为第二导电片510，第一导电片413、第二导电片510及连接片200均为铜片或排线，方便接线操作。上述的连接器400包括有电源接头411和信号接头412，电源依次通过电源接头411、第一伸出部、连接片200及第二伸出部将电源接入电源板结构500，信号依次通过信号接头412、第一伸出部、连接片200及第二伸出部将信号送入电源板结构500。具体描述请参照下述实施例。
上述实施例中，考虑到拼接的问题，底壳100上设有用以固定连接片200且辅助连接片200弯曲的连接块110，多个连接块110首尾连接以覆盖在连接片200上。相邻的底壳100通过连接片200连接，并通过连接块110将连接片200定位，使连接片200弯曲的时候被连接块110限位弯曲后弧度平滑过渡，相邻的两个连接块110可弯曲度数范围在-20°至20°之间，特别适合小型曲面显示屏的设计。
请参照图1、图2及图4，为了使LED单元屏的整体透光性更强，以及减轻屏体整体重量的问题，上述实施例中，PCB灯板300上开设有多条贯通PCB灯板300两侧的第一镂空部321。第一镂空部321的设置，增加了PCB灯板300的柔性，减轻了LED单元屏10的重量，也增强了透光性和PCB灯板300的散热性。进一步的，底壳100上亦开设有多条贯通的第二镂空部322，如此，可减轻底壳100的重量；另外，第二镂空部322与第一镂空部321对应设置，使得LED单元屏10具有较佳的通透性。上述的第一镂空部321与第二镂空部322均呈长条状，且第一镂空部321和第二镂空部322 底壳200的拼装方向平行分布，当然也可以是第一镂空部321和第二镂空部322垂直于底壳200的拼装方向分布多个，或者其他角度。
请参照图12，在一具体的实施方式中，底壳100远离PCB灯板300的一侧（背侧）凹设有用于收容连接片200的容置槽140，容置槽140位于底壳100的两端。当多个底壳100依次拼接后，所有底壳上的容置槽140位于同一直线上，当多个底壳100通过连接片200串接在一起后，连接块110可固定设置在容置槽140内以覆盖连接片200，多个底壳100弯曲后通过连接片200受力，PCB灯板300安装在底壳100上随着底壳100及连接片200的弯曲而弯曲。考虑到连接的稳定性问题，上述方案的连接片200的数量有两条，对应的底壳100的两端分别设有容置槽140，在多块底壳100拼接后，容置槽140位于平行的两个直线上，以分别收纳两条连接片200。
具体的，的连接片200为钢片，该钢片厚度为0.6 mm 至1mm。钢片的优选厚度为0.6mm，0.8mm及1mm，钢片的厚度低于0.6mm，则钢片的机械强度较差，钢片的厚度大于1mm，则钢片的柔性较差，不方便弯折。可以理解的，本方案的连接片200还可以选用其他金属或合金材质。上述的钢片通过连接块110压紧并定位在底壳100的容置内。连接块110的具体结构，请参照下述的实施例。
请参照图2和图3，上述连接块110通过螺丝与底壳100固定连接，该连接块110具有首端以及与首段配合的尾端，两个以上的连接块110首尾相接，以完全覆盖连接片200露出于底壳100外的一侧。该连接块110的首端具有朝连接块110外部伸出的呈环状的定位体111，连接块110的尾端端部设有一凹槽112，凹槽112的外端部边缘设有凸块113，凸块113可与环状的定位体111扣接配合。定位体111的内壁与凸块113的外壁卡接配合，具体的，定位体111的内壁形成有用以卡位凸块113的微小凸起114，凸起114与凸块113的外壁接触。当相邻的两个连接块110之间处于平直位置时，凸块113通过定位体111的凸起114限位而使定位体111不会晃动，凹槽112用于避让定位体111；当相邻的两个连接块110处于弯折的位置时，定位体111将伸入凹槽112内。上述的凸起114呈长条状设置，且定位体111靠近凸起114的位置开设有与凸起114垂直设置的条形槽。
请参照图4至图6，在一具体的实施方式中，PCB灯板300在两底壳100拼接的位置为镂空结构，因此本方案的PCB灯板300将在相邻底壳100的间隙处具有外露部分，该外露部分上具有硅胶套310包裹。硅胶套310的四个角位处分别朝硅胶套310外伸出一截用以定位的定位凸起311，使硅胶套310的纵截面整体呈“工”字形状。底壳100对应定位凸起311的位置形成有扣接位103，定位凸起311与扣接位103扣接配合，可以使硅胶套310与底壳100扣合在一起，避免脱落。当LED单元屏10弯曲的时候，定位凸起311与扣接位103之间的空隙形成硅胶套310的收缩空间。
请参照图6，进一步的，硅胶套310的表面中间设有一贯通的缝隙开口312，缝隙开口312的形状呈Z字形，缝隙开口312的两端分别延伸至硅胶套310的两侧边处。该缝隙开口312的作用主要是通过打开缝隙开口312将硅胶套310包在PCB灯板300的外露部分处。底壳100上设置的扣接位103，用于硅胶套310的定位凸起311扣在扣接位103处，从而避免硅胶套310在PCB灯板300弯曲时从底壳100脱落。缝隙开口312位于底壳100的正面侧，即PCB灯板300设有LED灯珠的一侧，设有缝隙开口312的该端端面高度位置略高于PCB灯板300的端面位置高度。在PCB灯板300上需要进行灌胶处理时，将硅胶套310的缝隙开口312朝向底壳100的正面侧设置，可以方便在对PCB灯板300进行灌胶，同时还可以将缝隙开口312一并填补，从而可以避免另外对其封胶的密封工艺步骤，避免硅胶套310的缝隙设置在PCB灯板300背面一侧的时候，需要将LED屏反复翻转操作的工艺步骤的问题出现，从而降低装配难度。
考虑到对缝隙开口312进行胶粘后也不一定能完全保证其被封死，因此，呈Z字形的缝隙开口312，可以延长缝隙的长度和曲折度，以降低缝隙处有水时，水从一端流入另一端，并进入PCB灯板300内部的概率，提高防水性能。
为了方便将PCB灯板300安装与底壳100上，在一具体的实施方式中，底壳100的正面设置PCB灯板300收纳槽，PCB灯板300整体呈具有较好弹性形变的片状体，为柔性的PCB灯板300，PCB灯板300的厚度为0.4mm-0.8mm，优选的厚度为0.6mm。相邻两个底壳100的拼接处形成有间隙，此处的PCB灯板300为镂空设计。
在基于上述实施例的基础上，为了提高装配效率以及提升柔性LED显示屏的平滑度，本实施例还对显示屏的拼接连接结构进行进一步的设计，具体如下：
请参照图1和图2，在一具体的实施例中，LED单元屏10包括中间单元块102以及位于中间单元块102相对两端的两端部单元块101，端部单元块101的宽度小于或等于中间单元块102的宽度的一半，优选的，端部单元块101的宽度为中间单元块102的一半；连接锁组件，其设有用于连接上下相邻LED单元屏10的第一连接锁610，以及用于连接左右相邻LED单元屏10的第二连接锁620；第一连接锁610和第二连接锁620均设置在端部单元块101上，多个LED单元屏10拼接时，相邻LED单元屏10的端部单元块101通过第一连接锁610上下锁接配合，通过第二连接锁620左右锁接配合。
具体的，当多个LED单元屏10拼接成显示幕墙时，每一LED单元屏10均具有包括中间单元块102及位于中间单元块102相对两侧的端部单元块101，中间单元块102的数量为至少一个。为了实现LED单元屏10之间的拼接，本方案采用连接锁组件。该连接锁组件包括用于上下连接相邻LED单元屏10的第一连接锁610，以及用于左右连接相邻LED单元屏10的第二连接锁620，如此可以实现LED单元屏10的上下与左右拼接。可以理解的，本方案的连接锁组件还可以为第一连接锁610或仅为第二连接锁620，以实现单列或单排的LED单元屏10的拼接。
第一连接锁610包括锁体611以及与锁体611配合的锁座612，锁体611和锁座612分离设置且位于相邻端部单元块101的拼接位置，以在相邻LED单元屏10上下拼接时，锁体611与锁座612锁接配合，实现相邻LED单元屏10的垂直固定。第二连接锁620包括锁体611以及与锁体611配合的锁座612，锁体611和锁座612分离设置，且位于相邻端部单元块101的拼接位置，以在相邻LED单元屏10上下拼接时，锁体611与锁座612配合，实现相邻LED单元屏10的水平固定。具体的，第一连接锁610及第二连接锁620的数量有两个，两个锁体611分别设置于LED单元屏10的第一侧，两个锁座612均设置于LED单元屏10的第二侧，以方便显示屏上下、左右方向的锁接。其中，第二侧为第一侧的对侧。
在一具体的实施方式中，第一连接锁610、第二连接锁620可以均为旋转锁，或者是插销锁等，并不限制的其锁结构。于上述实施例中，第一连接锁610的锁体611位于LED单元屏10的上侧，对应的LED单元屏10下侧为锁座612；第二连接锁620的锁体611位于LED单元屏10的左侧，对应的LED单元屏10右侧为锁座612。上述拼接的显示屏实现的是上下列方向的弯折，可以理解的，也可以实现左右方向排的弯折。
考虑到相邻LED单元屏10的拼接影响平滑过渡的问题，本实施例中，端部单元块101的宽度均为中间单元块102的一半。如此，在相邻LED单元屏10拼接时，上一LED单元屏10的端部单元块101与当前LED单元屏10的端部单元块101两者通过第一连接锁610固定连接，连接位置不会弯折，即第一连接锁610处不受弯折影响，两个端部单元块101作为一个整体相对中间单元块102弯折，又两者拼接宽度等于中间单元块102的宽度，故能够实现显示屏整体间隔均匀的弯折，从而使多个LED单元屏10拼接后平滑过渡，避免产生拼接棱角，有利于提升整体显示屏的显示效果。
具体的，LED单元屏10包括底壳100、设置在底壳100上的PCB灯板300，底壳100依次排布设置若干个且设置有PCB灯板300，位于LED单元屏10两对边上的底壳100与端部对应位置的PCB灯板300形成的端部单元块101，位于LED单元屏10中间的底壳100与中部对应位置的PCB灯板300形成的中间单元块102。中间单元块102的数量可以有多个，多个中间单元块102隔开设置。具体的，底壳100上设有用以将若干底壳100串接的连接片200，连接片200的两端分别延伸至第一连接锁610的锁体611和锁座612处，且连接片200的两端通过锁体611及锁座612压紧，这样可以通过锁体和锁座压紧连接片200的端部，避免连接片200端部翘起，影响端部位置处的弧度平滑过渡。多个中间单元块102之间通过连接片200串接，并使连接块110活动连接，连接块110挡在连接片200上，以避免连接片200直接露出在LED单元屏10外，并辅助连接片200在底壳上的定位和连接片200受力弯曲。
请参照图7至图10，进一步的，LED显示单元板的对侧分别设有连接器公座410，在相邻LED单元屏10拼接时，相邻连接器公座410插接有连接器公座420，以使相邻LED单元屏10上下连接。相邻连接器公座410通过一个连接器母座420插接固定，从而实现两块相邻LED单元屏的固定连接以及电源和信号的接通。
进一步的，多个LED单元屏10拼接后，为使相邻屏之间的间隙贴合紧密，还可以增加磁吸件。
请参照图1和图2，具体的，每一底壳100的两端分别设置有第一磁吸件710及第二磁吸件720，第一磁吸件710和第二磁吸件分别位于LED单元屏10的对侧边。第一磁吸件710可为磁块，第二磁吸件720可为铁块。当两块LED单元屏10水平拼接时，水平方向邻接的两个底座可通过第一磁吸件710与第二磁吸件720的相互吸引而连接，无需对位，方便操作。
于本实施例中，不但通过侧位的磁吸件吸引固定，同时也有第二连接锁620的锁接配合，方便对位，同时还可以使拼接后的整体结构更加稳定不易松脱。
在一具体的实施方式中，每一底壳100远离PCB灯板300一侧（背侧）的两端还固定设有U形卡头130。在多个底壳100拼接后，多个U形卡头130可以将加强杆定位在底壳100上，从而起到对底壳100的支撑作用，减少底壳100在不需要弯曲的时候而弯曲的问题产生，起到定型的作用。于本实施例中，该U形卡头130靠近底座的容置槽140设置。U形卡头130的侧位还设置有磁性接头，便于LED单元屏10定位在弧形固定位上。例如弧形墙体，该固定位为可以为设置于弧形墙体的磁性点位，在底座的磁性接头靠近墙体的磁性点位时，磁性接头与磁性点位相互吸引，即可将弯折呈弧形的多个LED单元屏10固定在对应固定位处，方便对弧形LED单元屏10的定型。
对于一般的显示屏而言，通常采用在单块显示屏的中间设置一个电源盒，其内设置了电源转接板和信号转接板，信号转接板上设置信号接收卡，电源转接板和信号转接板上均设置有铜柱，通过铜柱连接电源信号线，使电源信号线伸出电源盒之外，电源盒将电源转接板、信号转接板和电源信号线均收纳在其内，通常电源盒是整个LED单元屏上最为凸起的部分，导致显示屏电源信号部分***的问题，因此，在装配时，需要对电源盒的位置进行额外设置，不方便显示屏的装配。因此，本方案还对电源盒的结构进行了改进，提出了一种电源及信号结构装置。

进一步的，上述的第一导电片413及第二导电片510的材质均为铜，可以理解的，其他金属或合金的片状体均为本方案的可行方案。另外，当连接片200还可以为钢片，钢片具有较好弹性变形的片状体，便于显示屏的弯折。
请参照图7和图8，具体的，信号结构位于LED单元屏10的拼合位置边缘，连接器400包括信号接头412和电源接头411，信号接头412通过其焊脚415与PCB灯板300插接并焊接固定，电源接头411与第一导电片413接触。如此，以方便相邻LED单元屏10的信号连接，且电源接头411与第一导电片413电连接，提高装配效率。

本发明的技术方案中连接器用于相邻显示屏拼接时，连接器母座420与连接器公座410配合，连接器母座420的第一电源端子4111与连接器公座410的第二电源端子4112配合，同时连接器母座420的第一信号端子4121与连接器公座410的第二信号端子4122配合，实现相邻显示屏的电源及信号连接，方便装配，且能够提升产品整体的外观效果；通过朝外伸出的第一导电片413能够实现传导连接器公座410的电源，无需连接电线，能够提高显示屏的装配效率与电气连接的稳定性。
在一具体的实施方式中，所述第一信号端子4121和第二信号端子4122分别为接触式或插接式的公端子和母端子，第一电源端子4111为插针式插头，第二电源端子4112为针式插口，如此，可以实现第一电源端子4111与第二电源端子4112的插接配合。为了实现相邻显示屏的拼接，连接器母座420内的第一信号端子4121分为两组，两组第一信号端子4121通过PCB板集成设置在连接器盖4201内，如此，在相邻显示屏的两连接器公座410靠近时，连接器母座420直接扣接在连接器公座410上，两组第一信号端子4121分别与两个连接器公座410内的第二信号端子4122配合。为了提高连接器母座420及连接器公座410插接配合的可靠性，进一步的，两个所述第一信号端子4121平行设置于连接器盖4201内，连接器盖4201的外边缘的一组相对侧边分别设有卡扣，所述卡扣与显示屏对应位置处的卡头卡接。通过卡扣与卡头的卡接配合，使连接器母座420不容易从连接器公座410脱落，提高电气连接的可靠性。

进一步的，所述对接部上设有的导向槽431，所述导向槽431与电源插针平行设置；所述连接器公座410上设有导向柱432，所述导向柱432可与导向槽431插接配合。可以理解的是，上述的导向槽431与导向柱432的位置可以互换。
本实施例中，导向槽431的与凹槽相连接，且导向槽431的数量有两个，分别位于凹槽的两端；可以理解的，导向柱432的数量有两个，两个导向柱432分别对应导向槽431的位置设置。进一步的，该导向柱432的***端呈倒角设置，以方便导向柱432与导向槽431的配合。当导向柱432部分伸入导向槽431后，电源插针正对电源插孔，第一信号端子4121正对第二信号端子4122，实现连接器公座410与连接器母座420的导向。进一步的，第二信号端子4122的数量有多个，相邻第二信号端子4122之间形成有导向块433。
进一步的，所述对接部的***表面设有硅胶防水套440。上述的防水套140还可以替换为防水层，防水垫圈等，可以理解的，该硅胶防水套440还可以采用其他材质，如橡胶、树脂等防水材料。
在一具体的实施例中，所述连接器公座410的背面设有第一导电片413，所述第一导电片413的一端与连接器公座410的第二电源端子4112电性连接；所述第一导电片413的另一端包设有胶层4131。进一步的，所述第一导电片413的材质为铜。
本实施例中，在电源插针与电源插孔配合后，第一导电片413通过电源插孔的内壁可与电源插针电连接，也即，通过第一导电片413可以实现电源的传导，第一导电片413埋设于显示屏之间，且第一导电片413的另一端包设有胶层4131，该胶层4131的材质为硅胶，以起到绝缘防水的作用。可以理解的，第一导电片413的材质不局限于铜，还可以选用导电较佳的其他金属或合金。
上述连接器400方便装配，且能够提升产品整体的外观效果，无需连接电线，能够提高显示屏的装配效率与电气连接的稳定性。
进一步的，第二信号端子4122包括信号接收片416及与信号接收片416连接的焊脚415，连接器400通过焊脚415与PCB灯板300固定且电连接。该焊脚415呈弯折状设置，焊脚415的一端与信号接收片416电连接，焊脚415的另一端直接焊接在PCB灯板300上，以实现固定连接以及与PCB灯板300的电性连接，提升物理连接及电气连接的稳定性及可靠性。
具体的，为了提高连接效率，上述的第一导电片413、第二导电片510及连接片200均优选为铜片，也可以是排线。当第一导电片413、第二导电片510及连接片200均为铜片结构时，其具有较佳的导电性能，厚度较薄，整体规则平整占用空间少，方便接线连接。在一并列的方案中，第一导电片413、第二导电片510及连接片200亦可以为排线结构，通过排线结构亦可以实现较佳的电连接。且排线结构容易弯折，方便连接。另外，本方案还可以同时采用铜片及排线结合的连接结构，增加连接便捷性及机械强度。
为了避免漏电问题，第一导电片413段额外端端部设有硅胶包414，以避免第一导电片413露出显示屏外引起的漏电问题。电源盒的电源板结构500侧边还设有与其电连接的信号接收卡，该信号接收卡与电源板结构500位于同一行，能够接收信号，实现信号的中转。
具体的，外部电源接入时，连接器母座连接外部电源，并电源从连接器母座的电源插头接入连接器公座410的电源接头411处，经第一导电片413至连接片200，并经该连接片200至第二导电片510上，第二导电片510接入电源板结构，从而，通过电源板结构上的电源转接板对电源进行降压处理，供LED显示屏使用。对应的，信号的接入路径与电源的接入路径类似，此处不再赘述。
上述的，连接器母座410上还设有对接柱，连接器公座420上设有配合的对接孔，在连接器公座420与连接器母座410对接时，提供导向作用，使连接器公座420能够快速准确的和连接器母座410对接。
由于本方案采用了上述的结构，使得电源盒能够做得更加扁平，减少内部电源转接板或信号转接板的使用，且电源电流通过铜片和钢片进行传导，从电源转接板、信号转接板处分离出去，可以减轻电源转接板、信号转接板处的发热。由于采用信号线通常需要对线进行捆扎，信号线堆积，而导致走线位置处***，而铜片、钢片的结构更加平整，结构相比线路更加简单单一，避免采用信号线而使走线位置***的问题产生。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
