在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明的柔性拼接显示装置的优选实施例中的柔性显示装置的结构示意图，本优选实施例的柔性拼接显示装置20中的柔性显示装置包括像素单元23、扫描线22、数据线21以及驱动电路，其中驱动电路包括驱动芯片24、数据信号引线25以及扫描信号引线26。
其中像素单元23有多个数据线21和多个扫描线22交错形成，数据线21用于向像素单元23发送数据信号，扫描线22用于向像素单元23发送扫描信号，驱动芯片24用于生成数据信号以及扫描信号，数据信号引线25用于将数据信号发送至相应的数据线21，扫描信号引线26用于将扫描信号发送至相应的扫描线22。
本优选实施例中的驱动电路的数据信号引线25与相应的数据线21在柔性显示装置20的显示区域内进行连接，扫描信号引线26与相应的扫描线22在柔性显示装置20的设置驱动芯片24的一侧进行连接，且数据信号引线25从柔性显示装置20的设置驱动芯片24的一侧引入。这样柔性显示装置20的只有一侧具有引线连接点，这样本优选实施例中的柔性显示装置20进行拼接时，每个柔性显示装置20只有一侧会影响拼接的连接区域的显示效果，因此可进一步提升了该柔性显示装置20构成的柔性拼接显示装置的显示品质。
优选的，本优选实施例中的驱动电路的数据信号引线25和扫描信号引线26交错从驱动芯片24引出，这样可以最大程度的避免数据信号引线25与扫描信号引线26交叉，从而进一步提高数据信号和扫描信号的输出稳定性。
请参照图3，图3为本发明的柔性拼接显示装置的优选实施例中的柔性显示装置的结构示意图，本优选实施例的柔性拼接显示装置中的柔性显示装置30包括像素单元33、扫描线32、数据线31以及驱动电路，其中驱动电路包括驱动芯片34、数据信号引线35以及扫描信号引线36。
其中像素单元33有多个数据线31和多个扫描线32交错形成，数据线31用于向像素单元33发送数据信号，扫描线32用于向像素单元33发送扫描信号，驱动芯片34用于生成数据信号以及扫描信号，数据信号引线35用于将数据信号发送至相应的数据线31，扫描信号引线36用于将扫描信号发送至相应的扫描线32。
本优选实施例中的驱动电路的扫描信号引线35与相应的扫描线31在柔性显示装置30的显示区域内进行连接，数据信号引线36与相应的数据线32在柔性显示装置30的设置驱动芯片34的一侧进行连接，且扫描信号引线35从柔性显示装置30的设置驱动芯片34的一侧引入。这样柔性显示装置30的只有一侧具有引线连接点，这样本优选实施例中的柔性显示装置30进行拼接时，每个柔性显示装置30只有一侧会影响拼接的连接区域的显示效果，因此可进一步提升了该柔性显示装置30构成的柔性拼接显示装置的显示品质。
优选的，本优选实施例中的柔性显示装置30的数据信号引线35和扫描信号引线36交错从驱动芯片34引出，这样可以最大程度的避免数据信号引线35与扫描信号引线36交叉，从而进一步提高数据信号和扫描信号的输出稳定性。
本发明还提供一种柔性拼接显示装置。请参照图4和图5，图4为本发明的柔性拼接显示装置的优选实施例的结构示意图；图5为图1的A-A’的截面图。
本优选实施例的柔性拼接显示装置有多个柔性显示装置拼接构成，该柔性拼接显示装置包括显示区域41以及连接区域42，其中显示区域41位于每个柔性显示装置的中部，用于显示相应的图像画面，连接区域42位于相邻的两个显示区域41之间。
其中连接区域42由相邻的柔性显示装置的边缘相互叠加形成，因此连接区域42包括两个柔性显示装置的边缘，两个柔性显示装置的边缘相互重叠。
为了使相邻两个柔性显示装置的显示区域41的图像画面形成较好的过渡，本优选实施例中，根据相邻的两个显示区域41的伽马值，确定上述两个显示区域41之间的连接区域42的伽马值；根据相邻的两个显示区域41的色度值，确定上述两个显示区域41之间的连接区域42的色度值。其中伽马值用于反映区域画面41的明暗度或亮度，色度值用于反映区域画面42的色调以及饱和度。
连接区域42的亮度值以及色调值可以设置在相邻显示区域41的亮度值和色调值之间，即连接区域42的亮度值位于相邻的两个显示区域41的亮度值之间，连接区域42的色调值位于相邻的两个显示区域41的色调值之间。这样可避免连接区域42相对相邻的两个显示区域41发生亮度以及色调的突变，从而造成显示区域41之间的画面不连续现象。
具体的，可将连接区域42划分为第一连接区域421以及第二连接区域422，该连接区域42位于第一显示区域411和第二显示区域412之间，第一连接区域421靠近第一显示区域411，第二连接区域422靠近第二显示区域412，这样可将第一连接区域421的伽马值直接设置为第一显示区域411的伽马值，第二连接区域422的伽马值直接设置为第二显示区域412的伽马值，第一连接区域421的色度值直接设置为第一显示区域411的色度值，第二连接区域422的色度值直接设置为第二显示区域412的色度值，这样即可实现第一显示区域411和第二显示区域412无缝连接，避免了相邻显示区域41之间的画面不连续现象。
当然这里也可将连接区域42划分为两个以上的连接区域，相邻的连接区域42的伽马值以及色度值渐变，最靠近第一显示区域411的连接区域42的伽马值与第一显示区域411的伽马值相等或相似，最靠近第一显示区域411的连接区域42的色度值与第一显示区域411的色度值相等或相似，最靠近第二显示区域412的连接区域42的伽马值与第二显示区域412的伽马值相等或相似，最靠近第二显示区域412的连接区域42的色度值与第二显示区域412的色度值相等或相似。
优选的，为了保证柔性拼接显示装置的各个柔性显示装置的显示区域41的大小一致，可将第一连接区域421的大小和第二连接区域422的大小设置为相同，可进一步提升柔性显示装置的显示品质。
本优选实施例的柔性拼接显示装置进行画面显示时，可通过调整连接区域42处的一个柔性显示装置的边缘区域的伽马值，来设置连接区域42的伽马值，也可通过调整连接区域42处的两个柔性显示装置的边缘区域的伽马值，来设置连接区域42的伽马值。因此如何对连接区域42的伽马值进行设置可根据设计者以及用户的要求进行具体设定。
本优选实施例的柔性拼接显示装置进行画面显示时，可通过调整连接区域42处的一个柔性显示装置的边缘区域的色度值，来设置连接区域42的色度值，也可通过调整连接区域42处的两个柔性显示装置的边缘区域的色度值，来设置连接区域42的色度值。因此如何对连接区域42的色度值进行设置可根据设计者以及用户的要求进行具体设定。
本发明的驱动电路、柔性显示装置及柔性拼接显示装置通过信号引线连接点的设置，提升了柔性显示装置的显示品质。同时本发明的柔性拼接显示装置根据相邻的两个显示区域的伽马值以及色度值，确定两个显示区域之间的连接区域的伽马值以及色度值，提升了相邻两个显示区域之间的亮度连续性以及色彩连续性。解决了现有的柔性拼接显示装置由于拼接处的引线连接点导致显示装置的显示品质较差的技术问题。
综上所述，虽然本发明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发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
