Description

显示面板及具有该显示面板的显示装置 技术领域
本发明的实施例涉及显示面板及具有该显示面板的显示装置。 背景技术
如图 1所示为现有显示面板的原理结构图。 该显示面板主要包括用于控 制液晶取向的阵列基板 10和用于显像的彩膜基板 20。 显示面板通过柔性线 路板 30弯折对叠后与用于控制显示面板的主控线路板（图 1中未示出）相连 接。 具体的， 考虑到筒化加工工艺等方面的因素， 现有的柔性线路板 30与显 示面板的连接方式为， 将显示面板的阵列基板 10设置为大于彩膜基板 20, 阵列基板 10的开关电路布设在其长出彩膜基板的部分，而与主控线路板相连 接的柔性线路板 30对折后连接在阵列基板 10上的开关电路上。 由上述描述 可知， 现有显示面板为满足线路连接需要， 同时也为了尽可能扩大彩膜基板 20的显像面积， 势必会将阵列基板 10设置为大于彩膜基板 20。
如图 2a、 图 2b所示， 显示装置主要包括偏光片、 背光模组、 主控线路 板和框架， 其中的偏光片、 背光模组和主控线路板图中未示出。 结合图 1可 知， 背光模组射出的光线透过阵列基板 10由彩膜基板 20射出， 而彩膜基板 20小于阵列基板 10的结构关系， 很容易造成显示装置的边沿漏光， 因此， 为防止漏光， 需要确保彩膜基板 20用于遮光的黑矩阵 23具有足够的宽度， 同时， 还需要在显示装置正面设置前壳 41 (框架的前脸） ， 并且前壳 41必 须盖住彩膜基板 20的黑矩阵 23的全部（如图 2a )或者至少一部分（如图 2b ) 才能起到防漏光的作用，进而造成了前壳 41的宽度较大，导致显示装置的显 示区域较小。 在现有的结构关系之下， 无论如何改进， 彩膜基板的可视屏幕 区域 AA必然小于阵列基板的区域 BB, 如图 3所示， 其中的图 3a为对应于 图 2a的俯视示意图， 图 3b为对应于图 2b的俯视示意图。
综上分析可知， 受限于现有的显示面板及显示装置的结构关系， 使得显 示器的正面难以避免的需要设置宽度 4艮大的前壳， 显然， 目前的显示装置不 仅视觉效果不美观， 而且与消费群体对于窄边框、 超大显示面积的追求相背 离， 严重影响了显示装置的进一步推广应用。 发明内容

本发明的实施例要解决的技术问题之一是： 提供一种显示面板以及显示 装置， 以实现无框架、 超大显示屏， 和更美观的视觉效果。
第一实施例 （图 4a、 4b )
根据本发明第一实施例的显示面板包括阵列基板 100和彩膜基板 200, 在彩膜基板 200—侧或多侧设有电路连接单元 201; 所述电路连接单元 201 伸出所述阵列基板 100边沿。本申请的实施例提供了一种新的显示面板结构， 其中， 长出的彩膜基板用于布设显示面板的输入电路 600, 该输入电路 600 用于连接驱动电路与所述阵列基板 100的开关电路， 从而将驱动电路发出的 驱动信号传递到阵列基板 100的开关电路， 进而控制彩膜基板 200的显像。 这里， 驱动电路优选采用柔性线路板 300实现与输入电路 600的电性连接。 在本实施例中， 彩膜基板 200提供的可视屏幕区域 AA大于阵列基板 100, 从而增大了显示区域。 应理解， 在本申请的所有实施例中， 术语 "可视屏幕 区域" 是指用户面面对显示面板或显示装置时可以看到的屏幕区域。
在设计时， 例如可在阵列基板 100不变的前提下增大彩膜基板 200, 也 可在彩膜基板 200不变的前提下缩小阵列基板 100, 使得彩膜基板 200大于 阵列基板 100以便于在长出的彩膜基板 200上布设输入电路 600。 本发明实 施例提供的设计方案具有加工灵活， 适用范围广， 推广价值高的优点， 因此 适用于各类型号的显示面板的改进。
第二实施例 （图 5a、 5b )
根据本发明第二实施例的显示装置包括框架 400和第一实施例中提供的 显示面板。 该显示装置还包括偏光片、 背光模组和主控线路板等图 5a和图 5b中未示出的构件。 在该显示装置中， 偏光片位于彩膜基板 200上面， 背光 模组位于阵列基板 100下面， 主控线路板通过柔性线路板 300与显示面板的 输入电路 600相连接。 该显示装置中的阵列基板 100短于彩膜基板 200, 设 置于彩膜基板 200的边缘部分的电路连接单元 201对于背光模组透出的光线 具有遮挡作用， 从而起到防止光线泄漏的作用。 因此， 组装本实施例提供的 显示装置时， 不需要设置现有技术中的前壳 41 (参见图 2a、 2b、 3a和 3b ) 进行遮挡， 也就是说， 本实施例提供的显示装置可设置为图 5a和 5b示出的 无前壳结构。 可选择地， 可设置一小部分前壳以起到扣合各基板的作用。 显 然， 与图 3a、 图 3b所示的现有技术中有前壳 401的显示装置相比较， 本发 明实施例提供的显示装置的彩膜基板 200全部呈现于显示装置的正面， 如图 5a所示， 彩膜基板 200的全部区域为可视屏幕区域 AA, 区域 AA显然要大 于阵列基板的区域 BB, 因此， 从视觉效果上达到了真正无前壳、 超大全屏 显示的效果， 使得显示装置更加美观。
第三实施例 （图 6 )
本实施例是在第一实施例的基础上， 对显示面板的进一步改进。 第三实 施例与第一实施例提供的显示面板的区别例如在于光学膜片 500和 /或防漏 光单元 203。 当然， 该第三实施例的显示面板也可用于第二实施例提供的显 示装置中。 该第三实施例的显示面板包括阵列基板 100、 彩膜基板 200和光 学膜片 500, 其中， 阵列基板 100、彩膜基板 200和光学膜片 500自下而上顺 次压合而成。 在该显示面板中， 在彩膜基板 200在其一侧或多侧设有电路连 接单元 201 ,用于布设输入电路 600;所述电路连接单元 201伸出所述阵列基 板 100边沿， 以使得安装该显示面板的显示装置实现无边框显示效果。 彩膜 基板 200还包括用于显示图像的显像单元 202, 在所述显像单元 202与所述 电路连接单元 201之间设有用于防止光线外泄的防漏光单元 203, 该防漏光 单元 203优选为黑矩阵形式， 该电路连接单元 201采用便于刷涂电路的材质 制成， 且优选为黑色， 结合防漏光单元 203共同起到遮光的作用。 光学膜片 500可采用普通的偏光片， 设置为与彩膜基板 200对齐， 以便于安装到显示 装置时与无前壳 41的边框的配合。
第四实施例 （图 7 )
第四实施例是在图 6所示的第三实施例的基础上进行的进一步改进。 第 四实施例与第三实施例提供的显示面板的区别例如在于遮光板 501。 例如， 该第四实施例在光学膜片 500的一侧或多侧具有与所述彩膜基板 200的电路 连接单元 201相对应设置的遮光板 501 , 该遮光板 501的材质可采用黑矩阵 形式， 或者采用同于彩膜基板 200的电路连接单元 201的材质， 只要能够起 到防漏光作用即可。 该第四实施例中， 通过设置遮光板 501 , 可替代现有技 术中的前壳 41起到防漏光作用，而遮光板 501作为可视屏幕区域 AA的一部 分。较之具有前壳 41的现有技术的显示装置，具有该第四实施例的显示面板 的显示装置从视觉上增大了显示区域， 视觉上更加美观。 同时， 为筒化加工 工艺， 光学膜片 500与遮光板 501可设置为一次模压成型的一体结构。
显然， 该第四实施例的显示面板也可用于第二实施例的显示装置中。 第五实施例 （图 8a、 8b )
该第五实施例与图 7所示的第四实施例为并列的实施例。 第五实施例与 第四实施例的区别例如在于电路连接单元 201，。 例如， 图 7所示的第四实施 例中的光学膜片 500与遮光板 501为一次模压成型， 相区别的， 本第五实施 例中将遮光板 501与彩膜基板 200上的电路连接单元 201设置为一次模压成 型。如图 8b所示，该彩膜基板 200包括显像单元 202、在垂直于彩膜基板 200 的所在板面向上凸起的电路连接单元 201，、 位于显像单元 202和电路连接单 元 201之间的防漏光单元 203; 电路连接单元 201，下部可用于连接柔性线路 板， 其上部可用于遮光； 这样的显示面板用于显示装置中时可实现显示装置 的无前壳结构设计。 采用这样的电路连接单元的设计可将分层而置的电路连 接单元和遮光板合为一个整体， 筒化了显示面板的整体结构， 降低了制造难 度， 提高了制造精度。
显然， 该第五实施例的显示面板也可用于第二实施例所示出的显示装置 中。
第六实施例 （图 9 )
该第六实施例是在图 7所示的第四实施例的基础上进行的改进。 第六实 施例与第四实施例的区别例如在于遮像区 502。 图 7所示的显示面板在实际 工作时，由阵列基板 100透出的部分光线会沿彩膜基板 200的防漏光单元 203 斜向射出， 使得防漏光单元 203相对应的区域可能会显示有模糊图像。 在如 图 9所示的第六实施例中，为避免该模糊图像影响显示面板的整体显像效果， 可通过将光学膜片 500与彩膜基板 200的防漏光单元 203相对应的区域设置 为遮像区 502来解决。 也就是说， 可在在光学膜片 500和遮光板 501之间设 置遮像区 502, 用于遮蔽如图 7箭头方向的光线， 以去除显示面板边界的模 糊图像。 在现有技术中， 该模糊图像区域大都依靠前壳 41实现遮挡， 因此， 该第六实施例所提供的显示面板在实现在无前壳的前提下， 有效去除了模糊 图像。
显然， 为适应不同的加工工艺， 遮像区 502可设置为与光学膜片 500— 次模压成型， 或者遮像区 502可设置为与遮光板 501—次模压成型， 还或者 遮像区 502可设置为与光学膜片 500和遮光板 501一次模压成型。
显然， 该第六实施例的显示面板也可用于第二实施例所示出的显示装置 中。
第七实施例 （图 10 )
该实施例是在图 8a所示的第五实施例提供的显示面板的基础上进行了 去除模糊图像的改进。 即， 在图 8a所示的第五实施例的显示面板的基础上， 在光学膜片 500与彩膜基板 200的电路连接单元 201，之间设置遮像区 502。 在一个示例中， 遮像区 502可设置为与光学膜片 500—次模压成型。 该实施 例提供的显示面板具有在无前壳 41前提下充分去除模糊图像的效果，同时还 具有第五实施例提及的加工工艺筒单的优点。
当然， 该第七实施例的显示面板也可用于第二实施例所示出的显示装置 中。 并且， 依据不同的设计需求， 本发明的第七实施例可进行适当的变形， 如遮像区 502与遮光板 501、 彩膜基板 200可设置为一次模压成型。
另， 本发明的实施例所提供的显示装置， 可以为： 液晶面板、 电子纸、
OLED面板、 液晶电视、 液晶显示器、 数码相框、 手机、 平板电脑等具有任 何显示功能的产品或部件。
本发明的实施例与现有技术相比具有以下的优点：
1、本发明实施例中， 将显示面板的线路布设方式进行了改进， 进而使得 显示面板的彩膜基板长于显示面板， 依靠彩膜基板长出显示面板的区域来代 替现有技术中的前壳来实现防漏光的目的。 因此， 本发明实施例提供的显示 装置可省去前壳， 或者仅设置极小宽度的前壳用于压合各基板即可， 最终真 正达到了显示装置的无前壳结构设计， 且能够实现视觉上的显示屏区域大于 阵列基板的最大化显示效果， 使得显示装置的视觉效果更好。
2、本发明实施例提供的显示装置， 在达到省略前壳的目的的前提下， 对 于显示面板的设计较为灵活， 可在阵列基板不变的基础上增大彩膜基板的尺 寸， 也可在彩膜基板尺寸不变的基础上减小阵列基板的尺寸， 因此， 本发明 实施例的技术方案可适用于各类型号的显示装置，适用范围广，推广价值高。
3、 本发明实施例提供的彩膜基板伸出所述阵列基板的部分设有输入电 路,通过该输入电路可实现驱动电路与所述阵列基板的开关电路之间的连接， 进而控制彩膜基板的显像， 进一步的， 使得本发明的实施例在不影响显像的 基础上， 增大了彩膜基板。
4、本发明实施例提供的彩膜基板的电路连接单元除用作布设输入电路之 夕卜， 还可起到防漏光的作用。
5、本发明实施例中所采用的遮光片可以采用普通的光学膜片， 以降低成 本， 也可以包括遮光板和光学膜片， 通过遮光板与电路连接单元共同作用， 进一步提高防漏光的作用， 在一实施例中， 遮光板与彩膜基板的电路连接单 元设为一次模压成型， 成型后的彩膜基板的一侧或多侧具有凸起的电路连接 单元， 使电路连接单元下部具有连接柔性线路板的功能， 同时使其上部具有 遮光板的功能； 从而使显示面板及显示装置最终真正达到了显示装置的无前 壳结构设计， 采用这样的电路连接单元的设计。 可将原有的分层而置的电路 连接单元和遮光板合为一个整体； 筒化了显示面板的整体结构， 降低了制造 难度， 提高了制造精度。
虽然上文中已经用一般性说明及具体实施方式， 对本发明作了详尽的描 述， 但在本发明基础上， 可以对之做一些修改或改进， 这对本领域技术人员 而言是显而易见的。 因此， 在不偏离本发明精神的基础上所做的这些修改或 改进， 均属于本发明要求保护的范围。
