Description

说明书 发明名称:显示装置的盖板结构、 触控面板结构及防护面板结构 技术领域
[0001] 本发明涉及显示装置领域, 更具体的说, 涉及一种显示装置的盖板结构、 触控 面板结构及防护面板结构。
背景技术
[0002] 随着手机、 平板、 电视机等设备的发展与普及, 用于这些设备的平板显示的结 构也发生了诸多改进, 这些改进能够不断提高这类设备的用户体验, 且无论从 外观还是性能上, 能给用户带来更多的附加价值。
[0003] 在平板显示装置的上端一般设置有盖板结构, 主要通过印刷油墨方式将显示区 域表现出来, 显示盖板也用于给设备提供保护、 装饰以及触控等功能。 如图 1所 示, 以一种手机设备的触控盖板为例 (此显示盖板也包括电脑、 平板电视与其 他触摸显示装置) , 该盖板结构包括: 第一基板 110、 第二基板 120以及用于将 第一基板 110和第二基板 120粘接起来的光学胶 116 (OCA) 。 由于第一基板 110 的周围区域还印刷有油墨层 111, 因此, 在将第一基板 110与第二基板 120贴合吋 需要光学胶 116同吋填充由油墨层 111导致的中心凹陷区域, 这样就需要较厚的 光学胶 116才能达到较好的贴合效果, 但同吋, 由于光学胶 116是半固体胶质, 所以在填充所述凹陷区域吋, 也容易对较小的油墨转角区域填充不到位而易产 生气泡、 填充间隙等, 如图 1所述的填充间隙 112, 这样易造成贴合不良, 另一 方面, 印刷油墨后的凹陷区域与中间非印刷区存在高低差, 越是浅色的印刷为 了有更好的遮光性, 油墨层越厚, 则需要使用更厚的光学胶 116来填补, 这会增 加成本同吋也令显示设备变得更厚。 另外, 若第一基板 110采用塑胶材质如 PMM A+PC等复合塑料板吋, 在贴合后由于受热或低温吋容易发生层间分离致气泡溢 出等情况, 造成不良致显示装置不能够正常使用, 通过填平设计可避免这些不 良的发生。
技术问题
[0004] 本发明所要解决的技术问题是提供一种可实现更薄设计、 产品良率较高的显示 装置的盖板结构、 触控面板结构及防护面板结构。
问题的解决方案
技术解决方案
[0005] 本发明的目的是通过以下技术方案来实现的:
[0006] 1) 一种显示装置的面板结构, 包括:
[0007] 第一基板, 其周围印制有油墨层;
[0008] 第二基板, 叠置在所述第一基板上与所述油墨层相对;
[0009] 填平材料层, 形成在所述第一基板上, 用于填充所述油墨层围成的凹陷区域; [0010] 光学胶, 设置在所述第一基板与所述第二基板之间, 用于粘接所述第一基板与 所述第二基板。
[0011] 优选的, 所述第一基板为 PET基板。
[0012] 优选的, 所述第一基板为玻璃基板。
[0013] 优选的, 所述第一基板为 PMMA塑料板或 PC塑料板或 PMMA与 PC复合的塑料 板中的一种。
[0014] 优选的, 所述填平材料层为透明的紫外线光固化树脂
[0015] 2) 一种显示装置的触控面板结构, 包括:
[0016] 第一基板, 其周围印制有油墨层;
[0017] 第二基板, 叠置在所述第一基板上与所述油墨层相对, 所述第二基板上设置有 电容感应层;
[0018] 填平材料层, 形成在所述第一基板上, 用于填充所述油墨层围成的凹陷区域; [0019] 光学胶, 设置在所述第一基板与所述第二基板之间, 用于粘接所述第一基板与 所述第二基板。
[0020] 优选的, 所述第一基板为 PET基板。
[0021] 优选的, 所述第一基板为玻璃基板。
[0022] 优选的, 所述第一基板为 PMMA塑料板或 PC塑料板或 PMMA与 PC复合的塑料 板中的一种。
[0023] 3) 一种显示装置的防护面板结构, 包括:
[0024] 第一基板, 其第一面周围印制有油墨层, 其第二面用于贴附到显示装置上; [0025] 第二基板, 作为防护面板结构的最外层保护层, 叠置在所述第一基板上与所述 油墨层相对;
[0026] 填平材料层, 形成在所述第一基板上, 用于填充所述油墨层围成的凹陷区域; [0027] 光学胶, 设置在所述第一基板与所述第二基板之间, 用于粘接所述第一基板与 所述第二基板。
[0028] 本发明由于事先对第一基板 (带视窗印刷的透明基板) 的显示区即凹陷区域进 行了填平设置, 这样就使得光学胶的使用量降低, 降低光学胶的厚度, 同吋, 也避免了气泡、 填充间隙等不利因素的形成, 而正因为填平的设置, 使得光学 胶可以使用更薄的厚度即可达到较优的粘接效果, 从而可以降低整个手机的厚 度, 有利于显示装置薄型化的设计。
[0029] 另一方面, 由于传统工艺主要是在玻璃上进行显示区的油墨印刷, 而玻璃作为 无机材料, 对油墨的选择比较单一, 且不能够在强化后再次切割而只能先切割 成手机显示屏大小的小块并经强化后再单片印刷, 且印刷油墨后需要高温与长 吋间烘烤才能有较好的附着力, 在面板印刷吋需要有高的遮光性往往需要印刷 多次, 在玻璃上印刷则每印刷一次均需要进行高温及较长吋间的热烘烤才能让 油墨与玻璃有附着力, 这直接导致加工效率降低提高加工成本。 玻璃上加工的 另一缺陷是在玻璃上作各类花色图案印刷加工, 以及作一些 3D效果非常困难, 不但成本昂贵且效率低下, 在使用本发明填平工艺的前提下, 有效的解决了盖 板玻璃在应用上的劣势, 使得在防爆膜如 PET等膜材上较易实现这类多元化与个 性化的加工, 且 PET可以实现卷对卷的快速加工, 还可以低温烧烤固化, 从而降 低成本提高效率, 也让显示装置更具观赏性与提升附加价值。

[0037] 本发明提供了一种显示装置的盖板结构, 如图 2-图 7所示, 盖板结构包括: 第 一基板 110、 第二基板 120以及用于将第一基板 110和第二基板 120粘接起来的光 学胶 116; 其中, 第一基板 110的周围区域印制有油墨层 111, 用于形成显示区和 非显示区, 在显示区, 即第一基板 110上油墨层围成的凹陷区域填充有填平材料 层 115, 用于填充所述凹陷区域。 填平材料层 115可通过喷涂、 印刷、 点胶等方 式填充到所述凹陷区域中, 填平材料层可选择一种全透明的紫外线固化树脂, 具有良好的流平性与透明性, 通过紫外线光线固化。 本发明的实施方式之一直 接在玻璃的印刷油墨区实施填平技术, 由于事先对第一基板 110的显示区即凹陷 区域进行了填平设置, 这样就使得光学胶 116的使用量减薄, 降低了光学胶 116 的厚度同吋提高了透明度, 让产品更轻薄美观。 另外, 填平的实施也避免了气 泡、 填充间隙、 与光折射不均匀产生显示区边缘模糊、 色差等不利因素的形成 。 本发明的实施方式之二, 如先采用防爆膜印刷出显示区域并在防爆膜上实施 填平结构这种设计, 可以通过机器全自动印刷的生产与贴合, 在生产过程中可 直接减少人手而达到更高的生产效率与更低的单位生产成本, 同吋在防爆上可 实现更多的设计如与多色彩印刷与渐变的网点印刷、 3D印刷技术等无法或较难 在玻璃上实现的加工方式, (在玻璃实施这类加工方式不但效率低下且成本昂 贵) 。 这设计发明使得显示装置更具附加价值。
[0038] 本发明所述的显示装置的盖板结构, 可用于现有多种设备中, 如可以用在手机 、 平板电脑、 手提电脑、 电视机的显示显示面板或其他显示装置上作为防爆保 护、 装饰以及与触控驱动配合形成触控面板等应用。 以下通过几个关于手机的 触控面板、 防护面板等盖板结构的具体实施例对本发明作进一步的阐述。

[0041] 本实施例中, 所述第一基板 110采用玻璃基板结构, 第二基板 120为手机的触摸 驱动层, 该触摸驱动层可以是单层感应层结构, 也可以为双层感应层结构。 此 类结构的手机触控面板, 可以将光学胶的厚度从 150μηι降低到 50μηι, 这样使得 整个触摸屏乃至手机变得更为轻薄, 外观更漂亮, 手感更好, 而光学胶的使用 量更少, 成本也会更低。
[0042] 实施例二
[0043] 如图 3所示为另一种手机的触控面板结构 100b, 其包括: 玻璃基板 110b (第一 基板) 、 驱动模组层 120b (第二基板) 以及光学胶 116。 其中, 玻璃基板 110b的 周围区域印制有油墨层 111, 用于形成显示区和非显示区, 在显示区, 即玻璃基 板 110b上油墨层围成的凹陷区域填充有填平材料层 115, 用于填充所述凹陷区域 , 玻璃基板 110b与手机的驱动模组层 120b采用光学胶进行贴合。
[0044] 本实施例中, 模组驱动层 120b为手机的触摸驱动层与显示模组层二合为一, 即 触摸感应层直接设置在显示模组上了, 将所述玻璃基板 110b印制油墨层 111并与 与填平材料层 115结合后, 通过光学胶 116与触摸驱动层 120b进行贴合, 本实施 中触摸驱动层 120b的触摸感应区可以在上面, 也可以在下面。 同样的, 本实施 例可以将光学胶的厚度从 150μηι降低到 50μηι, 这样使得整个触摸屏乃至手机变 得更为轻薄, 外观更漂亮, 手感更好, 而光学胶的使用量更少, 成本也会更低
[0045] 实施例三
[0046] 如图 4所示为另一种结构的手机触控面板结构 100c, 与实施例一不同的是, 所 示第一基板采用的是高硬度的 PET基板 110c, 对手机表面起到防爆和装饰的作用 , 第二基板采用玻璃基板 120c, 在第二基板即玻璃基板 120c上设置有电容感应层 (图中未示出) , 以达到触控感应, 玻璃基板 120c之下是手机的显示模组 140 ( LCM) 。 在 PET基板上印刷或涂布油墨层 111与在玻璃基板上涂布油墨层 111更具 优势, 因为玻璃基板的高硬度及其材料特性, 一般在玻璃基板上只能形成黑色 或是白色的油墨层, 而且加工的成本昂贵, 同吋也难以 3D或者丰富色彩的加工 。 而本实施例通过在 PET基板涂布或印刷油墨层 111, 在工艺上可以实现更丰富 的印刷或 3D加工等, 丰富了手机的外观设计与颜色选择, 与在玻璃基板上进行 丝印或涂布油墨层不同的是, 采用 PET基板作为第一基板 110还可以实现卷对卷 的操作包括印刷与填平 (传统的玻璃需要钢化后再对玻璃进行印刷后再二次强 化, 需要大量的人手来操作, 效率比较底下, 且良率较低) , 而使用这个工艺 整个制程需要很少的人手, 主要通过机器自动化进行, 成本得以降低而效率与 良率可以提高, 适合大企业机械化批量生产, 特别是适用在大的平面触控上, 本工艺提高了产品的附加价值, 从而可以满足更多使用者的需求, 也令加工效 率更高成本更低。
[0047] 本实施例的改进同吋也是针对现有单层电容结构的手机触控面板, 现有单层电 容结构的手机触控面板需要在第一基板上先行涂布油墨层, 再在涂布层上面镀 上导电层以实现电容感应。 而由于电镀吋温度较高且工艺较为复杂, 不仅使得 油墨层的厚度受限与颜色的选择受到限制, 也由于玻璃基板在油墨层印刷视窗 区域后出现凹陷区域不平整使得镀上的导电线路层易出现断线等, 使得产品的 不良率较高与成本过高。 另外, 这种结构的设计, 还可以省去原来贴合在触摸 感应层上的防爆膜层, 直接采用 PET基板作为防爆膜层, 大大降低成本。
[0048] 实施例四
[0049] 图 5展示了第三种手机或平板电脑的触控面板结构 100d, 与实施例一不同的是 , 第一基板采用的是 PMMA塑料基板 110d, 当然, 也可以选择其它塑料基板如 P C塑料基板或者是 PMMA与 PC复合的塑料基板, 第二基板选择玻璃基板 120d, 显 示模组 140设置在最底层。 传统采用上述塑料基板的触控面板结构, 由于会在受 热或者是低温吋出现收缩或溢气的情况, 这样会导致与光学胶贴合性不好, 造 成分离或气泡溢出等不利因素。 但本实施例通过在塑料基板上先行填充填平材 料层, 避免了光学胶与塑料基板直接贴合, 从而消除了因受热或低温造成的不 良因素, 提高了产品的良率。
[0050] 实施例五
[0051] 如图 6所示, 本实施例提供的是一种智能手机的防护面板 100d, 主要对手机的 显示模组及其触控面板起到保护的作用, 其包括: PET基板 110e (第一基板) 、 玻璃基板 120e (第二基板) 以及光学胶 116。 其中, 第一基板即 PET基板 110e的 周围区域印制有油墨层 111, 用于形成显示区和非显示区, 在显示区, 即 PET基 板 110e上油墨层围成的凹陷区域填充有填平材料层 115, 用于填充所述凹陷区域 。 PET基板 110e通过其自带的硅胶层 150贴合到触摸屏手机 1 60上, 这样, 当手 机在受到冲击碰撞吋, 由所述玻璃基板 120e承受首次冲击, 因而即使发生碎裂, 也不会影响到下方的手机及其触控面板, 有效的保护了手机的触控面板。 同吋 , 本实施例自带硅胶的 PET基板 110e上方通过实施印刷与填平设置, 再与玻璃基 板 120e贴合到智能手机的屏幕上面, 让使用者可以通过变换手机保护屏, 如上述 实施例所述, PET基板 110e可以实现多种色彩及效果的印刷, 这设计就如给手机 定制不同的衣服般来达到更好的体验, 也令手机达到更好的视觉效果同吋延长 手机的使用寿命。
[0052] 实施例六
[0053] 本实施例也是提供的一种手机的防护装饰面板 100f, 主要对手机的显示模组及 其触控面板起到保护的作用, 同吋还起到装饰作用, 其包括: PET基板 110f (第 一基板) 、 玻璃基板 120f (第二基板) 以及光学胶 116。 防护装饰面板 100f通过 光学胶 117粘接到手机的触控玻璃 170, 触控玻璃 170之下是手机显示模组 180。 与实施例四、 五不同的是, 本实施例中第一基板采用的是 PET基板 110f,在 PET基 板 110f的周围区域印制有油墨层 111, 用于形成显示区和非显示区, 在显示区, 即 PET基板 110f上油墨层围成的凹陷区域填充有填平材料层 115, 用于填充所述 凹陷区域。 与在玻璃基板上进行丝印油墨层或印刷填平材料层不同的是, 采用 P ET基板 110f作为第一基板可以实现卷对卷的操作 (传统的玻璃需要钢化后对单 片玻璃进行印刷或丝印, 需要大量的人手来操作, 效率比较底下, 且良率较低 ) , 整个制程需要很少的人手, 主要通过机器自动化进行, 成本得以降低而效 率与良率可以提高, 适合大企业机械化批量生产, 特别是适用在大的平面触控 上。
[0054] 另外, 采用 PET基板 110f作为第一基板, 可以实现多元化的设计, PET材料基 板可以做多样化的表面处理如高硬度、 防指纹、 防 uv、 防反射等处理来达到不 同的保护目的, 在 PET基板上丝印油墨的限制相对而言较少, 可以印制更多色彩 更多图案包括 2D与 3D效果, 使得外观更为漂亮。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不能认 定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术 人员来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推演或替换, 都应当视为属于本发明的保护范围。
