本发明的实施方式
[0050] 下面将结合本申请实施例中的附图, 对本申请实施例中的技术方案进行清楚、 完整地描述。 显然, 所描述的实施例是本申请一部分实施例, 而不是全部的实 施例。 基于本申请中的实施例, 本领域普通技术人员在没有做出创造性劳动前 提下所获得的所有其他实施例, 都属于本申请保护的范围。
[0051] 图 1为本申请一实施例中一种液晶显示装置的示意图; 图 2为本申请一实施例中 一种液晶显示装置的导光板的展幵图, 请参阅图 1及图 2, 一种液晶显示设备, 包括导光板 1、 背光源 2、 液晶显示面板 3、 电路板 4以及卷带式芯片载体 5。 导光 板 1系用于背光, 导光板 1具有前表面 10、 后表面 11和四个侧面 12、 13、 14、 15 。 四个侧面 12、 13、 14、 15位于前表面 10及后表面 11之间, 四个侧面 12、 13、 1 4、 15是由宽侧面 12、 窄侧面 13、 第一侧面 14及第二侧面 15所组成, 第一侧面 14 及第二侧面 15位于宽侧面 12及窄侧面 13之间。 前表面 10是由平面 101及倾斜面 10 2组成, 倾斜面 102位于导光板 1的边缘且与窄侧面 13相邻, 因此如图 2所示第一 侧面 14及第二侧面 15呈现由梯形及长方形组成的五边形。 另, 至少一背光源 2系 设置于至少一侧面 12、 13、 14、 15, 如图 2所示本实施例的背光源 2设置于宽侧 面 12, 为侧光式液晶显示装置。 液晶显示面板 3设置于导光板 1的后表面 11。 电 路板 4设置于导光板 1的倾斜面 102上。 卷带式芯片载体 5连接液晶显示面板 3和电 路板 4。 集成电路 6设置在卷带式芯片载体 5上, 用于驱动液晶显示面板 3。
[0052] 在本实施例中, 由于背光源 2是设置于宽侧面 12, 因此光反射涂层 7可覆盖在导 光板 1的窄侧面 13、 第一侧面 14、 第二侧面 15及边缘上, 除了用以接收或反射背 光源 2由宽侧面 12发出的光之外, 也能够防止集成电路 6受到从背光源 2发出并通 过导光板 1而从其他边缘出来的光, 能够防止集成电路 6执行错误的液晶显示。
[0053] 在另一实施例中, 背光源 2是可设置于宽侧面 12及第一侧面 14, 例如 L形背光灯 条或两条直线型背光灯条分别设置于宽侧面 12及第一侧面 14, 背光源 2设置于越 多侧面 12、 13、 14、 15上, 可提供更均匀的光源, 但本案不限于此, 因此光反 射涂层 7相对于宽侧面 12及第一侧面 14, 光反射涂层 7可覆盖在导光板 1的窄侧面 13、 第二侧面 15及边缘上, 除了用以接收或反射背光源 2由宽侧面 12及第一侧面 14发出的光之外, 也能够防止集成电路 6受到从背光源 2发出并通过导光板 1而从 其他边缘出来的光, 能够防止集成电路 6执行错误的液晶显示。
[0054] 此外, 如图 1所示变频电路板 8或其他电路板亦可设置于导光板 1的倾斜面 102上 , 且与电路板 4相邻, 如此, 通过将电路板 4、 变频电路板 8或其他电路板安装在 导光板 1的倾斜面 102上, 液晶显示装置整体上可以变薄, 且导光板 1仅有在靠近 边缘处才幵始产生倾斜面 102, 因此导光板 1仍能维持光源的均匀性。
[0055] 另外, 图 4为本申请一实施例中一种液晶显示装置的制造方法的流程图, 请参 阅图 1、 图 2及图 4, 步骤 Sl, 形成用于背光的导光板 1。 步骤 S2, 形成背光源 2于 宽侧面 12, 且形成光反射涂层 7在窄侧面 13、 第一侧面 14及第二侧面 15上, 但若 背光源 2是形成于宽侧面 12及第一侧面 14, 则光反射涂层 7形成在导光板 1的窄侧 面 13及第二侧面 15上。 步骤 S3, 形成液晶显示面板 3于后表面 11。 步骤 S4, 形成 电路板 4于倾斜面 102上, 另外, 亦可形成变频电路板 8或其他电路板于倾斜面 10 2上。 接着, 步骤 S5, 形成卷带式芯片载体 5。 步骤 S6, 形成集成电路 6在卷带式 芯片载体 5上。

[0058] 此外, 如图 3所示变频电路板 8或其他电路板亦可设置于导光板 1的倾斜面 102上 , 且与电路板 4相邻, 如此, 通过将电路板 4、 变频电路板 8或其他电路板安装在 导光板 1的倾斜面 102上, 液晶显示装置整体上可以变薄, 且导光板 1仅有在靠近 边缘处才幵始产生倾斜面 102, 因此导光板 1仍能维持光源的均匀性。
