[0034] 如图 1所示的范例中, 显示模块 10中的液晶显示面板、 触控面板及光源的信号 是分别经由软性印刷电路板 102、 104、 106传输。 然而, 前述软性印刷电路板在 传输信号至系统吋, 必须分别经由三个端口电性连接, 此配置使得系统必须留 置足够的空间设置端口, 造成装置的大小受到限制。
[0035] 如图 2所示的范例, 已有发明创造试图利用焊接的方式, 将软性印刷电路板 104 及 106与焊接至软性印刷电路板 102上, 以电性连接并将信号汇整至软性印刷电 路板 102后, 再经由连接端 1020传输至系统。 藉此, 系统只须留置一个端口的空 间, 改善上述问题。
[0036] 在本申请的实施例中, 信号传输装置如图 3所示, 包括第一软性印刷电路板 110 及第二软性印刷电路板 120。 第一软性印刷电路板 110可电性连接显示模块 100及 系统 (未于图中表示), 且第一软性印刷电路板 110上设置有若干个端口部 202。 端 口部 202与第一软性印刷电路板 110的电路电性连接, 使其他组件可通过端口部 202与第一软性印刷电路板 102电性连接。 第二软性印刷电路板 120电性连接显示 模块 100, 且设置有端口连接件 201。 端口连接件 201与第二软性印刷电路板 120
的电路电性连接, 使其他组件可通过端口部 202与第一软性印刷电路板 110电性 连接。 上述的端口连接件 201匹配端口部 202, 两者间可依需求固定或拆卸。 端 口连接件 201可插入、 嵌合、 或利用弹片、 卡榫等任何已知存在的方式与端口部 202连接, 且在连接吋处于电性连接的状态, 使设置有端口连接件 201的第二软 性印刷电路板 120与具有端口部 202的第一软性印刷电路板 110电性连接。 总括而 言, 本实施例的信号传输装置可通过如图 6的流程制造, 其中步骤 S11到 S15是将 上述说明的步骤简要地叙述, 仅为示例的步骤, 可依需求作适当的修改。
[0037] 在上述实施例中, 端口部 202可为单个或多个, 且可设置在第一软性印刷电路 板 110的任一侧。 举例而言, 端口部 202可设置在第一软性印刷电路板 110的上表 面、 下表面、 四周边缘或其他可设置的位置。 惟上述设置至少须确保端口部 202可与第一软性印刷电路板 110的电路电性连接, 以供信号通过端口部 202输入 至或输出第一软性印刷电路板 110。
[0038] 另一方面, 端口连接件 201可为单个或多个, 且可设置在第二软性印刷电路板 1 20的任一侧。 举例而言, 端口部 202可设置在第二软性印刷电路板 120的上表面 、 下表面、 四周边缘或其他可设置的位置。 惟上述设置至少须确保端口连接件 2 01可与第二软性印刷电路板 120的电路电性连接, 以供信号通过端口连接件 201 输入至或输出第一软性印刷电路板 110。
[0039] 通过连接端口连接件 201及端口部 202, 第一软性印刷电路板 110可与第二软性 印刷电路板 120电性连接。 根据端口连接件 201及端口部 202设置的位置, 第一软 性印刷电路板 110及第二软性印刷电路板 120可对应进行不同设置。 举例而言, 第一软性印刷电路板 110可与第二软性印刷电路板 120位于同一平面并相互邻接 ; 或者第一软性印刷电路板 110可与第二软性印刷电路板 120位于不同平面; 或 者第一软性印刷电路板 110可与第二软性印刷电路板 120部分重叠。 然而, 实际 配置方式并不限于此, 惟至少需达到使第一软性印刷电路板 110与第二软性印刷 电路板 120电性连接的效果。
[0040] 在本申请的实施例中, 第一软性印刷电路板 110可直接连接显示模块 100, 或者 不直接连接显示模块 100。 在直接连接显示模块 100的情况下, 第一软性印刷电 路板 110可直接由显示模块 100接收信号; 在不直接连接显示模块 100的情况下,
第一软性印刷电路板 110可通过第二软性印刷电路板 120、 端口连接件 201及端口 部 202电性连接显示模块 10, 以从显示模块 100接收信号。 第一软性印刷电路板 110更可设置连接部 500, 用以电性连接系统。 并通过连接部 500传输至系统。
[0041] 第二软性印刷电路板 120可电性连接显示模块 100的光源或触控面板 (未于图中 表示), 传输光源提供的光源信号及 /或传输触控面板提供的触控信号。 第二软性 印刷电路板 120可与第一软性印刷电路板 110设置在显示模块 100的不同侧, 或者 可与第一软性印刷电路板 110设置在显示模块 100的同一侧。
[0042] 可选地, 所述第一软性印刷电路板 110及所述第二软性印刷电路板 120进一步通 过对准标记固定相对位置。 可选地, 除端口连接件 201及端口部 202外, 第一软 性印刷电路板 110及所述第二软性印刷电路板 120在通过对准标记对准后, 可通 过本领域习知的方式加强两者间的连结, 以固定两者间的相对位置。
[0043] 此外, 本申请的信号传输装置可进一步包括第三软性印刷电路板 130。 第三软 性印刷电路板 130可与第二软性印刷电路板 120具有相同功能。 亦即, 第三软性 印刷电路板 130可电性连接显示模块 100的光源或触控面板 (未于图中表示), 传输 光源提供的光源信号及 /或传输触控面板提供的触控信号。 同样地, 第三软性印 刷电路板 130可与第一软性印刷电路板 110设置在显示模块 100的不同侧, 或者可 与第一软性印刷电路板 110设置在显示模块 100的同一侧。 第三软性印刷电路板 130亦可与第二软性印刷电路板 120设置在显示模块 100的不同侧, 或者可与第二 软性印刷电路板 120设置在显示模块 100的同一侧。
[0044] 可选地, 第三软性印刷电路板 130可与第二软性印刷电路板 120分别传输不同信 号。 举例而言, 可设置使第三软性印刷电路板 130电性连接显示模块 100的光源 , 传输光源信号, 并设置使第二软性印刷电路板 120电性连接显示模块 100的触 控面板, 传输触控信号。
[0045] 在本申请的另一实施例中, 更可藉由将上述说明的信号传输装置设置在液晶显 示装置内用以传输信号, 进而提供一种液晶显示装置。
[0046] 除上述实施例以外, 还可依据实际状况及需求, 针对其中若干个组件进行优化 , 更加增强本申请的优点, 下文将以不同实施例进行示例说明。
[0047] 在本申请的示例性实施例中, 提供一种复合式信号传输装置。 针对上述第一软
性印刷电路板 110、 第二软性印刷电路板 120及第三软性印刷电路板 130之间的配 置关系进行优化, 不使用端口连接件 201及端口部 202的结构电性连接以上三者 , 而是直接将第一软性印刷电路板 110、 第二软性印刷电路板 120及第三软性印 刷电路板 130上整合成多层结构的复合式信号传输装置 700。 如图 4所示, 将与第 一软性印刷电路板 110、 第二软性印刷电路板 120及第三软性印刷电路板 130等效 的软性印刷电路板分别以第一软性印刷电路板 111、 第二软性印刷电路板 121及 第三软性印刷电路板 131表示, 以与前述实施例区隔。 复合式信号传输装置 700 是将第一软性印刷电路板 111、 第二软性印刷电路板 121及第三软性印刷电路板 131重迭, 并在三者间设置绝缘层 300的多层结构。 其中, 绝缘层 300设置若干个 通孔 310, 并分别设置导电柱 320于上述若干个通孔 310中, 使被分隔的第一软性 印刷电路板 111、 第二软性印刷电路板 121及第三软性印刷电路板 131间可电性连 接。 可选地, 第一软性印刷电路板 110可改用硬式电路板。 此外, 亦可进一步设 置绝缘层 300于第一软性印刷电路板 111下。
[0048] 绝缘层 300的材料可为例如: 聚酰亚胺 (Polyimide, PI)、 聚乙烯对苯二甲酸乙二 醇酯 (Polyethylene Terephthalate, PET)、 聚萘二甲酸乙二醇酉旨 (Polyethylene naphthalate' PEN)或其他本领域所常用的绝缘材料。 导电柱 320可为导电胶、 异方 向性导电膜或其他本领域所常用的导电材料。
[0049] 举例而言, 第二软性印刷电路板 121可电性连接显示模块 100的光源, 第三软性 印刷电路板 131可电性连接显示模块 100的触控面板。 第二软性印刷电路板 121及 第三软性印刷电路板 131通过设置于通孔 310中的导电柱 320进而与第一软性印刷 电路板 111电性连接, 再进一步通过连接部 500与系统电性连接。 然而, 上述仅 为示例, 实际实施的配置可依照需求进行调整。 例如, 第二软性印刷电路板 121 可与第三软性印刷电路板 131同样设置在第一软性印刷电路板 111上的同一平面 , 且分别采用上述方法与第一软性印刷电路板 111电性连接。
[0050] 在另一实施例中, 同样地, 针对上述第一软性印刷电路板 110、 第二软性印刷 电路板 120及第三软性印刷电路板 130之间的配置关系进行优化。 将第一软性印 刷电路板 110、 第二软性印刷电路板 120及第三软性印刷电路板 130上整合应用 类似于上一实施例中的多层结构的复合软性印刷电路板, 形成薄型复合式信号
传输装置 800, 结构如图 5所示。 在图 5中, 薄型复合式信号传输装置 800包含与 第一软性印刷电路板 110的电路等效的第一导电图形 112、 与第二软性印刷电路 板 120的电路等效的第二导电图形 122及与第三软性印刷电路板 130的电路等效的 第三导电图形 132。 其中, 第一导电图形 112可设置于任意绝缘性基板 (未于图中 标示)上, 且绝缘性基板上设置有导电部 500, 与上述结构电性连接。
[0051] 在薄型复合式信号传输装置 800的底部及上述第一导电图样 112、 第二导电图样
122及第三导电图样 132之间设置绝缘层 400, 并在其中设置层间导通结构 410, 使第一导电图样 112、 第二导电图样 122及第三导电图样 132之间通过层间导通结 构 410电性连接。 层间导通结构 410的形成, 包括在绝缘层 400中形成至少一个通 孔, 且所述通孔的孔壁是经由化学及电镀工艺形成具有导电性的镀层。 镀层的 材料可为金属或导电塑料, 或其他同样具有导电性的材料。 所述镀层电性连接 层间导通结构上层及下层的导电图样, 使其彼此电性连接。
[0052] 薄型复合式信号传输装置 800与前一实施例的复合式信号传输装置 700不同的地 方是, 第一导电图样 112、 第二导电图样 122及第三导电图样 132是由铜箔压印而 成, 其厚度远小于前述的第一软性印刷电路板 111、 第二软性印刷电路板 121及 第三软性印刷电路板 131。 因此, 薄型复合式信号传输装置 800的整体厚度可小 于复合式信号传输装置 700。
[0053] 此外, 薄型复合式信号传输装置 800的绝缘层 400虽可为单一材料制成, 但其形 成分为两个部分, 分别为原先即为固态的绝缘层, 及固化前的液态绝缘层, 其 中, 绝缘层 400的材料可为聚酰亚胺 (Polyimide, PI)。 绝缘层 400是设置在第一导 电图样 112、 第二导电图样 122及第三导电图样 132之间。 在绝缘层 400与上述三 种导电图样之间涂布未固化的液态聚酰亚胺的前聚体溶液, 亦即绝缘层 400固化 前的材料, 并经由加热步骤去除溶液中的有机溶剂即可使其固化形成绝缘层 400 。 藉上述方式设置的绝缘层 400除了具有绝缘效果外, 更能作为辅助贴合第一导 电图样 112、 第二导电图样 122及第三导电图样 132的黏着材料, 使薄型复合式信 号传输装置 800的结构更加稳固。
[0054] 同样地, 本申请更包括藉由将上述说明的信号传输装置设置在液晶显示装置内 用以传输信号, 进而提供一种液晶显示装置, 而所述液晶显示装置可具有上述
信号传输装置的各实施例所具有的益处及效果。 在不影响电路板的讯号传输效 果的同吋, 改变电路板的设置方式, 通过减少与系统相连的端口, 并免除焊接 步骤这种变因较大的制程, 更能减少出错机率, 提高产品良率。
[0055] 其中, 上述说明的信号传输装置还可以设置在其他电子装置中, 不限于显示装 置, 在应用于显示装置吋, 显示装置的种类可以是 LCD显示装置、 OLED显示装 置、 QLED显示装置、 曲面显示装置或其他显示装置。
[0056] 以上所述的内容仅是依照本申请优选地实施例详细说明, 而非限制本申请的权 利范围。 本申请相关领域具有通常知识者皆应理解, 在不违背本申请的技术原 理及精神下, 可对上述实施例作出修改与变化。 因此本申请的权利范围应如权 利要求书内容所述。
