Description

一种显示装置及其组装方法 技术领域
本发明涉及显示技术领域， 尤其涉及一种显示装置及其组装方法。 背景技术
由于液晶并非自发光显示元件， 现有的液晶显示装置通常由液晶显示 面板与背光源组成。 如何将显示面板与背光源牢固地组装在一起也成为了 提高液晶显示装置质量的关键。
目前的液晶显示装置通常是在背光源的边框贴附具有双面粘附力的遮 蔽胶带， 显示面板通过该遮蔽胶带与背光源粘结从而完成组装。 其中， 遮 蔽胶带通常采用物理粘结剂 （如亚克力系、 环氧系或硅酸系等材料） ， 该 物理粘结剂需要物理接触紧密才能产生强有力的粘结效果。 因此在液晶显 示装置的组装过程中， 需要对该贴附有遮蔽胶带的液晶显示装置进行按压， 如图 1所示， 以使得背光源 11和显示面板 12均能够与遮蔽胶带 13紧密地 粘结。
这样一种组装方法的不足之处在于： 背光源 11通常包括多层结构， 如 图 2所示， 背光源 11靠近显示面板的一侧表面通常具有一层由树脂材料形 成的三角形的棱镜结构 111; 当对贴附有遮蔽胶带的液晶显示装置进行按压 时， 极易破坏这些呈三角形的棱镜结构； 这导致背光源的出光效率降低， 从而严重影响显示装置的产品质量。 发明内容

为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图 作筒单地介绍， 显而易见地， 下面描述中的附图仅仅涉及本发明的一些实 施例， 而非对本发明的限制。

31-背光源, 32-显示面板， 33-遮蔽胶带， 331-光固化粘结剂层， 332- 物理粘结剂层， 333-透光基材。 具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进 行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员所获 得的所有其他实施例， 都属于本发明保护的范围。
根据本发明实施例提供的显示装置包括背光源、 显示面板以及用于粘 结背光源和显示面板的遮蔽胶带。 该遮蔽胶带为透光材料制成并且包括光 固化粘结剂层， 光固化粘结剂层接触背光源， 遮蔽胶带通过光固化粘结剂 层的光固化作用与背光源粘结固定。 采用这样一种遮蔽胶带无需对背光源 进行按压即可以使得遮蔽胶带有效粘结， 从而减少了显示装置的组装风险， 显著提高了显示装置的产品质量。
图 3示出了根据本发明第一实施例提供的显示装置。 如图 3所示， 该 显示装置包括： 背光源 31、 显示面板 32以及用于粘结背光源 31和显示面 板 32的遮蔽胶带 33。
遮蔽胶带 33为透光材料制成并且包括光固化粘结剂层 331 , 光固化粘 结剂层 331接触背光源 31 , 从而该遮蔽胶带 33与背光源 31通过光固化粘 结剂层 331的光固化作用进行粘结。
光固化粘结剂层 331 可以采用紫外线固化粘结剂制成， 例如可以采用 紫外线光刻胶。 相应的， 遮蔽胶带 33整体则可以采用透紫外线材料制成。 例如， 遮蔽胶带 33除了与背光源 31进行粘结的光固化粘结剂层 331夕卜， 还可以包括透光物理粘结剂层或透光基材， 该透光物理粘结剂层或透光基 材均采用可透过紫外线的材料制成。
在如图 3所示的显示装置中，遮蔽胶带 33仅包括光固化粘结剂层 331 , 因此光固化粘结剂层 331的一侧与背光源 31相接触， 另一侧则与显示面板 32相接触。 在进行光固化之后， 光固化粘结剂层 331将与背光源 31和显示 面板 21紧密粘结。 采用这样一种结构的遮蔽胶带可以无需对显示装置进行 按压。 当然应当理解， 采用光固化粘结剂作为遮蔽胶带也仅是举例说明， 而并非对本发明实施例所做的限制。
图 4示出了根据本发明第二实施例提供的显示装置。 如图 4所示， 遮 蔽胶带 33还可以包括物理粘结剂层 332, 该物理粘结剂层 332可以位于靠 近显示面板 32的一侧。
物理粘结剂层 332 可以采用透光的物理粘结剂制成。 例如， 该物理粘 结剂层 332可以采用亚克力系、 环氧系或硅酸系等材料制成， 本发明实施 例对此并不作限制。
当遮蔽胶带 33包括物理粘结剂层 332时， 该遮蔽胶带 33可以贴附于 显示面板 32的非显示区域（图 4中未示出） 。 例如， 遮蔽胶带 33可以贴 附于显示面板 32四周的边框区域。
由于遮蔽胶带贴附于显示面板的非显示区域， 所以当对显示面板进行 按压时， 可以避免遮蔽胶带对背光源的有效发光区域产生破坏。 另一方面， 由于遮蔽胶带整体均采用透光材料制成， 当对显示面板进行按压时， 操作 人员可以透过遮蔽胶带观察到背光源结构， 从而可以人为地避开背光源的 发光结构， 进一步减少了显示装置的组装风险。
采用这样一种结构的显示装置， 遮蔽胶带 33中位于一侧的光固化粘结 剂层 331可以通过光固化作用与背光源 31进行粘结， 位于另一侧的物理粘 结剂层 332可以通过按压与显示面板 32紧密粘结。 由于遮蔽胶带 33靠近 显示面板一侧表面采用的是物理粘结剂， 与光固化粘结剂相比， 物理粘结 剂具有重复粘结性， 这样一来， 在模组组装的过程中提高了组装的重工性， 便于背光源进行重复组装以及组装矫正， 进一步提高了显示装置的质量。
图 5示出了根据本发明第三实施例提供的显示装置如图 5所示， 当遮 蔽胶带 33同时包括光固化粘结剂层 331与物理粘结剂层 332时， 该遮蔽胶 带 33还可以包括：
透光基材 333 ,该透光基材 333可以位于光固化粘结剂层 331和物理粘 结剂层 332之间。
在本发明实施例中， 透光基材 333可以采用 PET (聚对苯二甲酸类塑 料） 、 无纺布， 铜箔， 铝箔等或其他可透过紫外线的材料制成。
采用透光基材 333可以有效分隔开光固化粘结剂层 331和物理粘结剂 层 332, 防止光固化粘结剂层 331和物理粘结剂层 332之间相互渗透， 从而 保证了遮蔽胶带粘结背光源 31和显示面板 32的牢固性。
采用这样一种遮蔽胶带无需对显示装置进行按压即可以使得遮蔽胶带 有效粘结， 从而减少了显示装置的组装风险， 显著提高了显示装置的产品 质量。
根据本发明第四实施例还提供一种显示装置组装方法， 该方法包括：
5601、 在背光源和显示面板之间贴附遮蔽胶带， 该遮蔽胶带为透光材 料制成并且包括光固化粘结剂层， 该光固化粘结剂层接触背光源；
5602、 用光线透过显示面板照射光固化粘结剂层， 遮蔽胶带为， 该遮 蔽胶带与背光源通过所述光固化粘结剂层的光固化作用进行粘结。
光固化粘结剂层可以采用紫外线固化粘结剂制成， 例如可以采用紫外 线光刻胶。 相应的， 遮蔽胶带整体则可以采用透紫外线材料制成。 例如， 遮蔽胶带除了与背光源进行粘结的光固化粘结剂层外， 还可以包括透光物 理粘结剂层或透光基材， 该透光物理粘结剂层或透光基材均采用可透过紫 外线的材料制成。
根据本实施例提供的显示装置组装方法， 遮蔽胶带通过光固化粘结剂 层的光固化作用与背光源粘结固定， 使得无需对显示装置进行按压即可以 使得遮蔽胶带有效粘结， 从而减少了显示装置的组装风险， 显著提高了显 示装置的产品质量。
进一步地， 遮蔽胶带可以贴附于显示面板的非显示区域。
遮蔽胶带还可以包括物理粘结剂层， 该物理粘结剂层可以位于靠近显 示面板的一侧， 该物理粘结剂层采用透光的物理粘结剂制成。 相应的， 本 发明实施例提供的显示装置组装方法还可以包括： S603、 按压显示面板的 表面， 将该显示面板与遮蔽胶带的物理粘结剂层按压粘结。
物理粘结剂层可以采用透光的物理粘结剂制成。 例如， 该物理粘结剂 层可以采用亚克力系、 环氧系或硅酸系等材料制成， 本发明实施例对此并 不作限制。
当遮蔽胶带包括物理粘结剂层时， 该遮蔽胶带可以贴附于显示面板的 非显示区域。 例如， 遮蔽胶带可以贴附于显示面板四周的边框区域。
由于遮蔽胶带位于显示面板的非显示区域， 当对显示面板进行按压时， 可以避免遮蔽胶带对背光源的有效发光区域产生破坏。 另一方面， 由于遮 蔽胶带整体均采用透光材料制成， 当对显示面板进行按压时， 操作人员可 以透过遮蔽胶带观察到背光源结构， 从而可以人为地避开背光源的发光结 构， 进一步减少了显示装置的组装风险。
上述方法中， 利用遮蔽胶带中位于一侧的光固化粘结剂层通过光固化 作用与背光源进行粘结， 利用位于另一侧的物理粘结剂层通过按压与显示 面板紧密粘结。 这样， 由于遮蔽胶带靠近显示面板一侧表面采用的是物理 粘结剂， 而与光固化粘结剂相比， 物理粘结剂具有重复粘结性， 所以在模 组组装的过程中提高了组装的重工性， 便于背光源进行重复组装以及组装 矫正， 进一步提高了显示装置的质量。
进一步地， 当遮蔽胶带同时包括光固化粘结剂层与物理粘结剂层时， 该遮蔽胶带还可以包括：
透光基材， 该透光基材可以位于光固化粘结剂层和物理粘结剂层之间。 需要说明的是， 在本发明实施例中， 透光基材可以采用 PET (聚对苯 二甲酸类塑料） 、 无纺布， 铜箔， 铝箔等或其他可透过紫外线的材料制成。
采用透光基材可以有效分隔开光固化粘结剂层和物理粘结剂层， 防止 光固化粘结剂层和物理粘结剂层之间相互渗透， 从而保证了遮蔽胶带粘结 背光源和显示面板的牢固性。
采用这样一种遮蔽胶带进行显示装置的组装无需对显示装置进行按压 即可以使得遮蔽胶带有效粘结， 从而减少了显示装置的组装风险， 显著提 高了显示装置的产品质量。
以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局 限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可 轻易想到变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明 的保护范围应所述以权利要求的保护范围为准。
