【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
请参照图1至图2，本发明实施例提供一种拼接式显示器背板，该拼接式显示器背板由两个第一主支架10、两个第二主支架20以及两个辅支架30拼接形成。
在本实施例中，两个第一主支架10相互平行，两个第二主支架20相互平行，两个第二主支架20的端部分别与两个第一主支架10的端部连接，形成一个封闭的矩形外框。两个辅支架30相互平行，两个辅支架30的端部分别与两个第一主支架10的端部之间的中间位置连接，进而起到辅助支撑作用。在其他实施例中，辅支架30的端部可以设置成分别与两个第二主支架20的端部之间的中间位置连接，且其数量可以根据需要设置成至少一个或取消。进一步，拼接式显示器背板的支架可根据实际需要进行任意设置，例如由两个L形的支架拼接形成拼接式显示器背板。
在本实施例中，第一主支架10、第二主支架20和辅支架30上分别设置有补强肋11、21和31。补强肋11、21和31优选由第一主支架10、第二主支架20和辅支架30冲压形成。各补强肋11、21和31分别包括位于拼接位置且间隔设置的至少两个第一补强部以及用于连通该至少两个第一补强部的第二补强部。具体来说，补强肋11包括分别位于第一主支架10端部的两个第一补强部111、位于第一主支架10的中间位置的两个第一补强部113以及用于连通第一补强部111和第一补强部113以及两个第一补强部113的第二补强部112。补强肋21包括位于第二主支架20的端部的两个第一补强部211和用于连通第一补强部211的第二补强部212。补强肋31包括位于辅支架30的端部的两个第一补强部311和用于连通第一补强部311的第二补强部312。进一步，位于第一主支架10和第二主支架20的端部的第一补强部111、211优选呈T形设置。位于辅支架30的端部以及第一主支架10或第二主支架20的中间位置的第一补强部311和113优选呈+形设置。
在本实施例中，相互拼接的第一主支架10、第二主支架20或辅支架30的第一补强部111、113、211或311在拼接位置相互重叠且嵌合设置。
请参见图3，第一主支架10的第一补强部111和第二补强部112在第一主支架10的一侧形成一凸起（未标示），同时在第一主支架10的另一侧形成一凹陷（未标示）。第二主支架20的第一补强部211和第二补强部212在第二主支架20的一侧形成一凸起（未标示），在第二主支架20的另一侧形成一凹陷（未标示）。在第一主支架10和第二主支架20的拼接位置，第二主支架20的第一补强部211在第二主支架20的一侧形成的凸起嵌入至第一主支架20的第一补强部111在第一主支架10的一侧形成的凹陷内，并且优选彼此贴合设置。 进一步，第一补强部111、113、211或311在其他拼接位置也可以采用上述设置方式，在此不再赘述。
通过上述方式，利用补强肋11、21和31中的第二补强部112、212或312连通位于拼接位置的第一补强部111、113、211或311，并将相互拼接的第一补强部111、113、211或311设置成相互重叠且嵌合，由此可提高强度传递性，进而提高背板的机械强度。进一步，上述补强肋11、21和31优选连接成至少一闭合的环形补强结构。请参照图4，在本实施例中，在两个补强肋11和两个补强肋21之间、两个补强肋11、补强肋21和补强肋31之间以及两个补强肋11和两个补强肋31之间均形成了闭合的环形补强结构，由此进一步提高了背板的机械强度。
本发明进一步提供一种液晶显示器，包括了上述拼接式显示器背板。
本发明的有益效果是：与现有技术相比，本发明拼接式显示器背板由至少两个支架拼接形成，使得背板的重量减轻，材料成本降低。同时，该至少两个支架分别设置有补强肋，位于拼接位置的补强肋之间相互连通，并相互重叠且嵌合设置，使得机械强度提高。
