如图 1-3 所示, 本发明提供一种显示装置的拼接式背板结构, 其包 括: 一呈 L形的第一安装件 10、 及分别呈一字形的一第二安装件 20、 一 第三安装件 30、 一第四安装件 40及一第五安装件 50, 第一安装件 10、 第 二安装件 20及第三安装件 30 的端部依次连接而形成一封闭的矩形外框 100, 第四安装件 40置于外框 100内且两端分别与外框 100连接, 第五安 装件 50 置于外框 100 内且两端分别与外框 100 连接而形成镂空状的背 板。 本发明的背板分别由 L形及一字形的安装件拼接而成, 外框结构强度 较佳, 成本低, 易于制作, 且可将同一模具生产出来的各安装件在分割后 进行拼接以形成不同尺寸的背板, 不同尺寸的背板应用于各种不同尺寸例 如 32寸、 46寸以及更大或更小尺寸的液晶显示装置, 使不同尺寸的背板 的生产模具可以共用, 同时, 作为本发明的优选实施例, 第四安装件 40 与第五安装件 50 结构相同, 使第四安装件及第五安装件的生产模具可共 用, 从而大大降低材料成本及模具成本, 拼接形成镂空状背板。 本发明釆用 L形第一安装件 10、 第二安装件 20及第三安装件 30来形 成外框 100, 使外框 100具有较佳的外框结构, 克服拼接式背板的强度不 足的缺陷。 该第一安装件 10与第二安装件 20及第三安装件 30之间、 第 四安装件 30与第一安装件 10及第二安装件 20之间、 及第五安装件 50与 第一安装件 10及第二安装件 20之间釆用铆接、 螺丝锁附或镭射焊接的连 接方式。 作为本发明的一优选实施例, 第一安装件 10 具有相连的天侧部 101及左侧部 102, 第二安装件 20与第一安装件的左侧部 102连接, 第三 安装件 30与第一安装件的天侧部 101连接, 第四安装件 40的两端及第五 安装件 50的两端分别与天侧部 101及第二安装件 20连接, 且第四安装件 40及第五安装件 50之间相互平行。
优选的, 本发明还在各安装件连接处釆用相同的加强筋结构来进一步 加强背板的强度, 该第一安装件 10在与第二安装件 20、 第三安装件 30、 第四安装件 40及第五安装件 50的连接处分别具有凸起的第一加强筋 12, 第二安装件 20在与第一安装件 10、 第三安装件 30、 第四安装件 40及第 五安装件 50 的连接处分别具有凸起的第二加强筋 (未图示) , 第二加强 筋与第一加强筋 12重叠配合, 第三安装件 30在与第一安装件 10及第二 安装件 20连接处分别具有凸起的第三加强筋 32, 第三加强筋 32分别与第 一加强筋 12及第二加强筋重叠配合, 第四安装件 40在与第一安装件 10 及第二安装件 20连接处分别具有凸起的第四加强筋 42, 第四加强筋 42分 别与第一加强筋 12及第二加强筋重叠配合, 第五安装件 50在与第一安装 件 10及第二安装件 20连接处分别具有凸起的第五加强筋 52, 第五加强筋 52 分别与第一加强筋 12 及第二加强筋重叠配合。 本发明通过加强筋结 构, 进一步提高了背板拼接处强度, 进一步克服拼接式背板强度不足的缺 陷, 满足背板的各类设计需求, 各安装件之间可釆用铆接、 螺丝锁附或镭 射焊接等连接方式, 作为本发明的优选实施例, 各安装件之间釆用铆接的 连接方式, 第一加强筋 12的两侧凸设有容置槽, 第四加强筋 42的两侧的 铆接头 421上置于容置槽内 (如图 3所示) 。
进一步的, 本发明根据需要, 对不同位置的安装件使用不同的材料制 作, 该外框 100对应一背光模组的背光光源的位置处的安装件由高导热材 料制成, 外框的其余安装件、 第四安装件及第五安装件分别由镀锌钢板或 塑料制成, 以满足散热等需求并使产品成本最低化。 具体的, 本发明的背 板应用于左右两侧入光的背光模组中时, 该第一安装件 10 与第三安装件 30 分别由高导热材料制成, 由于第一安装件 10 呈 L 形, 增加了散热面 积, 有利于散热, 本发明所述的高导热材料为热导率(导热系数) W/(m · k)200 以上的导热材料, 优选釆用铝材料, 以满足导热的需求, 同时, 第 二安装件 20、 第四安装件 30及第五安装件 40分别由镀锌钢板或塑料制成 以降低产品的成本同时保持背板具有一定的强度, 作为本发明的另一优选 实施例, 背板应用于左右任意一侧的单侧入光的背光模组中时, 该第一安 装件 10由高导热材料制成, 第二安装件 20、 第三安装件 30、 第四安装件 40及第五安装件 50分别由镀锌钢板或塑料制成, 增加散热面积, 有利于 散热; 或者, 该第三安装件 30 由高导热材料制成, 第一安装件 10、 第二 安装件 20、 第四安装件 40及第五安装件 50分别由镀锌钢板或塑料制成, 由于第三安装件 30 呈一字形, 在一定程度上节省了成本; 另外, 背板应 用于上下天地单侧或两侧入光的背光模组中时与上述左右侧入光方式中的 安装件材料选择同理, 在此不再赘述之。
以上所述, 对于本领域的普通技术人员来说, 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形, 而所有这些改变和变形 都应属于本发明权利要求的保护范围。
