所述线路板121包括依次连接的第一部分121a和第二部分121b，所述第一部分121a设置于所述显示面板110上并覆盖所述拼接缝113，所述发光体122设置于所述第一部分121a上，所述第二部分121b设置于所述拼接缝113内，所述第二部分121b一端与所述第一部分121a电连接，所述第二部分121b的另一端经弯折后与所述控制板130电连接。第一部分121a和第二部分121b为一体式结构，第二部分121b利用拼接缝113连接第一部分121a与所述控制板130，充分利用拼接缝113内的空间。
所述线路板121为柔性线路板（FPC），线路板121包括水平设置的第一部分121a和第二部分121b，所述第二部分121b包括竖直段和弯折段。在另一种实现方式中，线路板121为印刷电路板（PCB），包括水平设置的第一板体、竖直设置于拼接缝113内的第二板体以及水平设置的第三板体，第一板体设置于两所述显示面板110上并覆盖拼接缝113，第二板体上端与第一板体连接，第三板体一端与第二板体下端连接，第三板体的另一端与控制板130连接。
在本实施例中，线路板121的两侧壁分别延伸至相邻显示面板110的显示区112a与非显示区112b的交界处，形成对位于拼接缝113两侧的非显示区112b的全面覆盖，避免非显示区112b的暴露以影响拼接屏100的显示画质。
本实施例中作为显示面板110的液晶显示面板具有显示面积大、稳定性高和成本低廉等优势，但显示面板110无法实现全面屏显示，即显示面板110具有边框（非显示区112b），若直接将多个显示面板110拼接为大尺寸拼接屏，显示面板110之间具有较大的拼接缝113，无法实现无缝拼接，而将线路板121覆盖所述拼接缝113，则可实现拼接屏100显示画面的无缝显示。其中，所述显示面板110的数量为多个，呈阵列排布、拼接，线路板121覆盖任意相邻两显示面板110之间的拼接缝113。
在本发明另一实施方式中，参照图3~图4，拼接屏100’包括反光件150，反光件150凸出设置于线路板121的侧壁上，反光件150覆盖所述线路板121的侧壁，具体地，反光件150覆盖第一部分121a的侧壁或者覆盖第一板体的侧壁，反光件150朝向显示区112a一面为反射面，反光件150的反射面可对显示面板110的显示区112a发出的光线进行反射，将彩色画面重新射出，将显示面板110与灯板120之间的段差用反射的彩色画面连接起来，达到消除灯板120侧壁黑边的效果。
在本实施例中，反光件150的颜色为黑色，材质为反光胶，形成对线路板121侧壁的封胶，由于反光件150为黑色，与周围视觉无明显差异，故而可通过反射面进行反射。作为优选实现方式，反光件150朝向显示区112a一面开设有凹槽151，凹槽151的内表面为反射面，显示区112a发出的光线进入凹槽151内，反射面可对进入凹槽151内的光线进行反射后射出，将显示面板110与灯板120之间的段差用反射的彩色画面连接起来，达到消除灯板120侧壁黑边的效果。凹槽151的开口度可根据显示需要进行调节。反光件150可通过模压治具在反光胶胶体上模压形成所述凹槽151结构。
本实施例中的线路板121的侧壁延伸至靠近拼接缝113的非显示区112b的表面，即线路板121覆盖相邻显示面板110的一部分非显示区112b，所述反光件150则覆盖远离拼接缝113的非显示区112b的表面，即，反光件150覆盖另一部分非显示区112b，反光件150与线路板121配合形成对位于拼接缝113两侧的非显示区112b的全面覆盖。
在本发明的另一实现方式中，参照图5~图6，拼接屏100’’包括反射层140和导光件160，导光件160设置于反射层140远离灯板120一面，所述导光件160至少部分覆盖邻近所述拼接缝113的显示区112a，即，导光件160除覆盖部分非显示区112b外，还覆盖部分显示区112a，未被导光件160覆盖的显示区112a发出的光线进入导光件160后经过漫反射后射出，消除因灯板120与显示面板110之间段差而导致的黑边。而被导光件160覆盖的显示区112a发出的光线进入导光件160后，经过漫反射后射出，实现对显示区112a发出的光线的导光作用，结合反射层140的反射，消除因灯板120与显示面板110之间段差而导致的黑边。在本发明另一实现方式中，导光件160直接设置于灯板120的侧壁上，导光件160部分覆盖邻近所述拼接缝113的显示区112a。
在本发明又一实施方式中，参照图7~图8，拼接屏100’’’包括反射层140和反光件150，反射层140设置于线路板121的侧壁上，反光件150凸出设置于反射层140远离线路板121侧壁一面，反光件150的反射面可对显示面板110的显示区112a发出的光线进行漫反射，将彩色画面重新射出，将显示面板110与灯板120之间的段差用反射的彩色画面连接起来，达到消除灯板120侧壁黑边的效果。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
