在实施例一或实施例二的基础上，所述显示面板还包括液晶盒测试区60。下面以在实施例二的基础上进行说明。
所述液晶盒测试区60位于所述绑定区100的两侧，且位于所述第二柔性电路板区30的外侧。所述液晶盒测试区60用于通过所述液晶盒测试区60的测试焊盘输送测试信号，所述测试信号用于对液晶显示面板进行测试。

与实施例一或实施例二相比，本实施例虽然设置了液晶盒测试区60，但本实施例中的液晶盒测试区60的宽度小于现有技术中液晶盒测试区的宽度。本实施例液晶盒测试区60中的测试焊盘61的数量小于现有技术中液晶盒测试区中的测试焊盘的数量。
现有技术中，假设所述第一柔性电路板区内设置有M个第一焊盘，相邻两所述第一焊盘的间距为L/M，L为第一柔性电路板的宽度。而在实施例一与实施例二中，将所述第一柔性电路板中的N个所述第一焊盘设置于现有显示面板中的液晶盒测试区，即实施例一与实施例二中所述第二柔性电路板区的所述第二焊盘。
与现有技术相比，本申请中的所述第一柔性电路板区的相邻两所述第一焊盘的间距为L/（M-N），即大于现有技术中相邻两所述第一焊盘的间距。因此，部分所述第一焊盘的转移，增加了相邻两所述第一焊盘的间距，降低了柔性电路板区与柔性电路板的对位连接精度。
在实施例三中，由于液晶盒测试区的设置，实施例三中的所述第二柔性电路板区的宽度，小于实施例一或实施例二中所述第二柔性电路板区的宽度。虽然增加了相邻两所述第一焊盘的间距，降低了柔性电路板区与柔性电路板的对位连接精度，但提升的幅度较实施例一或实施例二的小。
根据本申请的另一个方面，还提供了一种显示模组，所述显示模组包括所述显示面板，还包括在所述显示面板上依次设置的触控层、偏光层和盖板层。
根据本申请的又一个方面，还提供了一种电子装置，所述电子装置包括所述显示模组；所述电子装置包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
所述显示模组的工作原理、所述电子装置的工作原理与所述显示面板的工作原理相似，所述显示模组的工作原理以及所述电子装置的工作原理具体可以参考所述显示面板的工作原理，这里不做赘述。
本申请提供了一种显示面板及显示模组，所述显示面板包括绑定区，所述绑定区包括驱动芯片区、第一柔性电路板区及第二柔性电路板区；所述第一柔性电路板区内设置有第一焊盘，所述第二柔性电路板区内设置有第二焊盘，所述第一焊盘和所述第二焊盘用于输出相应驱动信号。本申请通过在第一柔性电路板区两侧设置第二柔性电路板区，减小了所述第一柔性电路板区中第一焊盘的数量，增加了相邻两所述第一焊盘的间距，一定程度上降低了柔性电路板区与柔性电路板在对接过程中对精度的要求，提高了显示面板的品质。
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。
