Definitions
- the present invention relates to a liquid crystal display device, and more particularly to a pixel structure having a graded electrode pitch, which is a distance between adjacent first pixel electrode strips and second pixel electrode strips.
- liquid crystal displays Since liquid crystal displays have good quality imaging capabilities and low power consumption, they are often used as display devices. In general, liquid crystal display devices utilize several different active array technologies. For example, a twisted nematic display includes twisted liquid crystals and non-twisted liquid crystals at different angles to allow light to pass therethrough. However, due to the long relaxation time of liquid crystal cells, the application of twisted nematic displays is limited by those relatively low data transfer rates, and the twisted nematic technology has a limited viewing angle range.

Description
液晶显示装置的像素结构 技术领域
本发明涉及一种液晶显示装置, 且特别是涉及一种具有渐变的电极间距的像素结构, 所述电极间距是指相邻的第一像素电极条纹与第二像素电极条纹之间的距离。 背景技术
由于液晶显示器具有品质良善的显像能力且用电量低, 因此常作为显示装置。 一般来 说, 液晶显示装置利用数种不同的有源阵列技术。 举例来说, 扭转向列型显示器包含于不 同角度下的扭转液晶与非扭转液晶, 借此让光线通过。 然而, 由于液晶单元的长弛豫时间 (relaxation time), 扭转向列型显示器的应用受限于那些相对低的数据传输速率, 且扭转向 列型技术具有视角范围的限制。
其他阵列技术诸如:横向电场效应 (In plane switching; IPS)的结构或垂直配向 (Vertical alignment; VA)的结构, 可以提供更弹性的显示特性。 在垂直配向的显示器中, 当未施 加电压时, 液晶与基材保持垂直, 以在交叉配置的偏光板之间产生黑屏。 当施加电压时, 液晶偏移至歪斜位置, 借此让光线通过而产生灰阶显示。 在横向电场效应的技术中, 对液 晶单元施加电场的相对电极 (共用电极与像素电极)配置于相同基材上, 如此液晶可以在同 一平面重新定向 (转向)。 垂直配向的显示器具有液晶显示面板的高对比度与高反应速度的 优点, 而横向电场效应的结构则在大视角与斜视角下产生较小的色差。
垂直配向 -横向电场效应技术 (Vertical alignment- in plane switching; VA-IPS)是使用 IPS电极结构搭配垂直配向显示模式, 其中共用电极与像素电极配置于相同基材上。 当未 施加电压时, 液晶与基材保持垂直。 然而, 在大视角与斜视角下的色彩失真 (也就是色偏 效应), 将是垂直配向-横向电场效应显示器的问题。
在横曲配向 (transverse bend alignment; TBA)结构中存在与垂直配向-横向电场效应显 示器相似的技术。 在横曲配向显示器里, 除了在垂直配向 -横向电场效应显示器中, 配置 于相同基材上的共用电极与像素电极外, 在基材的相对侧上还会配置对向电极, 此对向电 极电性连接共用电极, 使得对向电极与共用电极被施加相同的电压, 以对液晶单元形成电 场。 当未施加电压时, 在横曲配向显示器中的液晶与基材保持垂直, 此与垂直配向 -横向 电场效应显示器相似。 同样的, 横曲配向技术于大视角与斜视角具有类似的色偏问题。
一般来说, 解决色偏问题的方法是增加像素中的电极间距数 (电极间距是像素电极与 共用电极之间的距离)。 举例来说, 图 13示出在像素中带有不同电极间距数的液晶显示装 置的灰阶伽玛曲线图。 如图 13的 B1/B2曲线与 C1/C2曲线所示出, 当视角斜度增加时, 像素中带有 14组电极间距的液晶显示装置, 比起像素中带有 4组电极间距的液晶显示装 置, 具有更平滑的伽玛曲线 (也因此色偏性能较佳)。 然而, 随着液晶显示装置缩小尺寸的
趋势, 像素尺寸也缩小, 因此配置于像素内的电极间距数也受到限制。
因此, 一种迄今尚未处理的需求存在于所属技术领域中, 凸显上述的缺陷与不足。 发明内容

以下将通过参考搭配的附图来更充分地描述本发明,其中附图示出本发明的例示性实 施方式。然而, 本发明可以通过许多不同的形式实施且不应当被诠释为受限于其中所阐述 的实施方式。 相反的, 借着提供这些实施方式, 将使得本公开文本详尽、 完整且充分地传 达本发明的范围给本领域技术人员。 相似的参考标号是标示相似的元件。
本文所使用的词汇仅为了描述特定实施方式, 并非用以限制本发明。 除非上、 下文明 确指出 "一"与 "该"不包含多个的形式, 本文所提到的单数形式 "一"与 "该"也包含 多个的形式。 应进一步了解到, 当本文提到词汇 "包含" 、 "包括"或 "具有"时, 这说
明了所述的特征、 区域、 整体、 步骤、 操作、 元件、 部件、 区段与 /或构件的存在, 但不 排除一或多个其他的特征、 区域、 整体、 步骤、 操作、 元件、 区段、 构件与 /或上述的群 组的存在或附加。
应了解到, 虽然本文所使用的词汇 "第一" 、 "第二"与 "第三"等, 可用来描述不 同的元件、 构件、 区域、 层与 /或剖面, 但是这些元件、 构件、 区域、 层、 区段与 /或剖面 不应被这些词汇所限制。 这些词汇仅用来区分元件、 构件、 区域、 层、 区段或剖面与其他 元件、 构件、 区域、 层、 区段或剖面。 因此, 下述的第一元件、 构件、 区域、 层、 区段或 剖面可以使用词汇第二元件、 构件、 区域、 层、 区段或剖面而不脱离本发明的教示。
此外, 本文所使用的关系词汇例如: "下"或 "底"和 "上"或 "顶"可用来描述图 面所示出的一元件与另一元件的相对关系。 应了解到, 除了图面所示出的装置方向之外, 关系词汇还欲包含装置的不同方向。 举例来说, 如果在图面其中之一中将装置颠倒, 原本 描述在其他元件 "下"侧的元件, 会变成位于其他元件的 "上"侧。 因此, 依据图面的特 定方向, 例示性词汇 "下"可包含 "下"与 "上"两种方向。 同样的, 如果在图面其中之 一中将装置颠倒, 原本描述 "低于"其他元件的元件或原本描述在其他元件之下的元件, 会变成 "高于"其他元件。 因此, 例示性词汇 "低于"与 "在…之下"可包含 "高于"与 "低于"两种方向。
除非有其他相反的定义, 所有本文中所使用的词汇 (包含技术词汇与科学词汇), 与本 发明所属技术领域中普通技术人员所理解的具有相同的意义。应进一步了解到, 除非在本 文中有明确的定义, 词汇 (诸如在常用字典中所定义的词汇)的涵义应解释得与在相关技术 的上、 下文与本公开文本的上、 下文一致, 而不是以理想化或过于形式的意义来解释。
本文所使用的词汇 "大约"、 "大概"或 "约略"所修饰的数值的误差范围一般是容 许在百分之二十以内, 较佳地是在百分之十以内, 更佳地是在百分五之以内。 若本文未明 确叙明, 所公开的数值就是 "约略 "的, "约略 "意谓可推断出 "大约"、 "大概 "或"约 略" 的词汇的含义。
通过结合所搭配的附图图 1至图 11,将对本发明的实施方式做出陈述。依据本发明在 此实现且广泛描述的目的, 本发明的一实施例是关于一种利用垂直配向-横向电场效应显 示技术, 或横曲配向技术的液晶显示器, 其通过设计像素结构, 使得像素结构具有变化的 电极间距, 所述的电极间距是介于像素的第一像素电极条纹与第二像素电极条纹之间。
图 1A与图 1B示出依据本发明一实施方式的液晶显示装置 100的两局部剖面图。 其 中图 1A示出当未施加电压时的液晶显示装置 100的液晶的方向, 而图 1B示出当施加电 压时的液晶显示装置 100的液晶的方向。依据本实施方式, 液晶显示装置 100利用垂直配 向 -横向电场效应显示技术并具有第一基材 110、 第二基材 120、 液晶层 130与像素阵列。 第一基材 110与第二基材 120是相对设置, 借此定义一单元间隙于其间。液晶层 130设置 于单元间隙中, 单元间隙介于第一基材 110与第二基材 120之间, 且液晶层 130定义有多 个液晶单元。 像素阵列具有多个像素。 这些像素形成于第一基材 110上。 每一像素连接所
对应的液晶单元, 且每一像素包含第一像素电极与第二像素电极。第一像素电极具有多个 第一像素电极条纹 172与 173。第二像素电极具有多个第二像素电极条纹 162、 163与 164。 如图 1A与图 1B所示, 剖面是沿着一条与第二像素电极条纹以及第一像素电极条纹实质 交错的线所取得, 借此较佳地示出液晶显示装置 100的结构, 并且为了示出细部结构的目 的, 图 1A与图 1B仅示出液晶显示装置 100的像素的局部剖面。
如图 1A所示, 第一基材 110与第二基材 120相对设置, 借此定义单元间隙于其间。 液晶层 130设置于单元间隙中, 单元间隙介于第一基材 110与第二基材 120之间, 且液晶 层 130定义有多个液晶单元 (图 1A仅示出一液晶单元)。 每一液晶单元包含多个液晶 132。 此外, 绝缘层 140与保护层 150分别在第一基材 110上形成。 如图 1A所示, 由于未将电 压施加在液晶显示装置 100上, 因此所有的液晶均与第一基材 110与第二基材 120的表面 垂直。
依据本发明, 每一像素连接所对应的液晶单元并包含第一像素电极与第二像素电极。 第一像素电极具有多个第一像素电极条纹。第二像素电极具有多个第二像素电极条纹。 图
1A示出像素的第二像素电极 (Vcom)的第二像素电极条纹 162、 163与 164, 以及像素的第 一像素电极 (Vpixel)的第一像素电极条纹 172与 173。 多个第一像素电极条纹 172与 173 以及多个第二像素电极条纹 162、 163与 164交错设置, 如此第一像素电极条纹 172位在 相邻的第二像素电极条纹 162与 163之间,而第一像素电极条纹 173位在相邻的第二像素 电极条纹 163与 164之间。 此外, 多个电极间距 Pi、 P2、 P3与 P4定义为介于第一像素电 极条纹 172与 173以及第二像素电极条纹 162、 163与 164之间的距离。 具体而言, 通过 邻近的第一像素电极条纹 172与第二像素电极条纹 162定义电极间距 Pi。通过邻近的第一 像素电极条纹 172与第二像素电极条纹 163定义电极间距 P2。通过邻近的第一像素电极条 纹 173与第二像素电极条纹 163定义电极间距 P3。通过邻近的第一像素电极条纹 173与第 二像素电极条纹 164定义电极间距 P4。 此外, 每一电极间距均具有宽度, 且电极间距 Pi、 P2、 ?3与 P4的宽度并非都相同。 具体而言, ?3与 P4所具有的宽度大于?1与?2所具有的 宽度。
图 1B示出当施加电压时的液晶显示装置 100。由于此液晶显示装置 100与图 1A相同, 因此以相同的附图标记标示所有的元件。 当对液晶显示装置 100施加电压时, 第一像素电 极条纹 172与 173以及第二像素电极条纹 162、 163与 164将产生多个电场, 因此液晶层 130内的液晶 132受到电场的驱使而移动或转向至倾斜的位置。 如图 1B所示, 由于电极 间距 P3与 P4的宽度与电极间距 Pi与 P2的宽度不相同,因此介于电极条纹之间的电场范围 也会不相同。
通过多样的实施方式, 可以了解电极条纹之间的电极间距的宽度变化。 举例来说, 图
2至图 8B示出依据本发明不同实施方式的液晶显示装置的电极结构的平面图, 为方便说 明电极条纹的设计及相对位置, 暂时不示出其余元件, 例如开关元件。 如图 2所示, 第一 像素电极 270具有多个第一像素电极条纹例如 271-274、 271a-274a与脊部 (或中间部) 275。
在此例示性实施方式中, 第一像素电极条纹 271-274、 271a-274a自脊部 (或中间部) 275对 称延伸, 但不限定延伸至何处, 借此每一第一像素电极条纹 271、 272、 273、 274、 271a, 272a, 273a以及 274a与脊部 (或中间部) 275定义 (或形成)一第一角度 ocl于其间。第二像素 电极 260具有多个第二像素电极条纹 261-265、 261a-265a、顶部 266与底部 266a。顶部 266 及底部 266a可分开形成且彼此平行, 且顶部 266及底部 266a与第一像素电极 270的脊部 275平行对齐。第二像素电极条纹 261、 262、 263、 264或 265分开并自顶部 266朝向第一 像素电极 270的脊部 275延伸, 而第二像素电极条纹 261a、 262a, 263a, 264a或 265a分 开并自底部 266a朝向第一像素电极 270的脊部 275延伸, 借此每一第二像素电极条纹与 第一像素电极 270的脊部 275定义一第二角度 0C2于其间。 此外, 顶部 266、 底部 266a、 第二像素电极条纹 261-265与 261a-265a对称于第一像素电极 270的脊部 275形成。 如图 2所示, 在本实施方式中, 第二角度 0C2与第一角度 ocl相同。
根据本发明, 第二像素电极条纹 261-265与 261a-265a和第一像素电极条纹 271-274 与 271a-274a交错设置, 借此定义八个电极间距 Pi、 P2、 P3、 P4、 P5、 P6、 P7 与 P8。 电极 间距 P3、 P4、 P5与 P6中的每一电极间距所具有的宽度分别大于电极间距 Pi、 P2、 P7 与 P8 中的每一电极间距所具有的宽度。具体而言, 电极间距其中至少一个的宽度与其他电极间 距的宽度不同。如此一来, 由于第一像素电极条纹与第二像素电极条纹之间具有不同的电 极间距, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。 此外, 如图 2所示, 第二像素电 极条纹 261-265与 261a-265a和第一像素电极条纹 271-274与 271a-274a平行设置,如此虽 然电极间距的宽度不同,但是每一电极间距沿邻近的共用电极条纹或第一像素电极条纹的 延伸方向而具有均匀而固定的宽度。在本例示性实施方式中, 每一第二像素电极条纹与每 一第一像素电极条纹均为直条纹。
根据另一实施方式,每一电极间距的宽度可沿两邻近的第一像素电极条纹与第二像素 电极条纹之间的参考线的延伸方向而变化。举例来说, 由于第二像素电极条纹与第一像素 电极条纹沿不同的方向延伸, 因此每一电极间距的宽度可以变化。 换句话说, 角度 ocl 与 角度 0C2彼此不同。如图 3A所示,第二像素电极 360具有多个第二像素电极条纹例如 361、 362、 363、 364 与 365, 且第一像素电极 370具有多个第一像素电极条纹例如 371、 372、 373与 374(图 3A与图 3B仅针对相对于中间部而位于上半部的第一像素电极条纹与第二像 素电极条纹标号)。 每一第二像素电极条纹与第一像素电极条纹均为直条纹。 虽然第二像 素电极条纹 361、 362、 363、 364 及 365彼此等距, 且第一像素电极条纹 371、 372、 373 及 374也彼此等距, 但是每一第一像素电极条纹沿第一方向 301延伸, 而每一第二像素电 极条纹沿第二方向 302延伸。第二方向 302与第一方向 301不同, 因此形成介于第一方向 301与第二方向 302之间的锐角 θ。 因此, 在由邻近的第一像素电极条纹与第二像素电极 条纹所定义的八个电极间距中的每一电极间距,沿邻近的第一像素电极条纹与第二像素电 极条纹之间的参考线的延伸方向, 会具有变化的宽度。 因此, 在电极结构的每一剖面中, 每一电极间距之间的电极间距比会不同, 且由于在不同剖面中, 各电极间距沿电极条纹会
有不同的宽度, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。
本领域技术人员当知, 如图 3A与图 3B所示, 当第一像素电极条纹与第二像素电极 条纹沿不同的方向延伸时,电极间距 P的宽度定义为垂直于参考线 R且位于第一像素电极 条纹与第二像素电极之间的距离,此参考线 R介于邻近的第二像素电极条纹 362与第一像 素电极条纹 372之间, 在本例中, 参考线 R为直线。 在本例中, 邻近的第二像素电极条纹 362或第一像素电极条纹 372相对于参考线 R的距离为 d, 其中电极间距 P的宽度为 P = 2*d。 参考线 R位于邻近的第二像素电极条纹 362与第一像素电极条纹 372之间, 且邻近 的第二像素电极条纹 362与第一像素电极条纹 372相对于参考线 R对称。如图 3A与图 3B 所示, 举例来说, 参考线 R以相同的长度依序排列且 /或彼此平行。
图 4示出液晶显示装置的电极结构的另一实施方式。 如图 4所示, 第二像素电极 460 具有多个第二像素电极条纹 461、 462、 463与 464, 且第一像素电极 470具有多个第一像 素电极条纹 471、 472与 473。 第二像素电极条纹 461、 462、 463与 464彼此不等距, 且第 一像素电极条纹 471、 472与 473也彼此不等距。 此外, 每一第一像素电极条纹沿第一方 向 401延伸,而每一第二像素电极条纹沿第二方向 402延伸。第二方向 402与第一方向 401 不同, 因此形成介于第一方向 401与第二方向 402之间的锐角 θ。 如图 4所示, 虽然电极 结构只具有六个电极间距,但是每一电极间距的宽度会彼此不同且会沿邻近的电极条纹之 间的参考线的延伸方向而呈现连续变化。 由于邻近的电极条纹间的电极间距为多变, 且上 述多个电极间距具有不同的宽度, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。
在另一实施方式中, 通过将电极条纹分成不同的区段, 每一电极间距的宽度可沿邻近 的第一像素电极条纹与第二像素电极条纹之间的参考线的延伸方向而变化。举例来说, 由 于所有的第二像素电极条纹与第一像素电极条纹都分成两区段, 因此每一电极间距可以变 化。 如图 5Α所示, 第二像素电极 560具有多个第二像素电极条纹 561、 562、 563、 564 与 565, 且第一像素电极 570具有多个第一像素电极条纹 571、 572、 573与 574。 此外, 第二像素电极条纹 561、 562、 563、 564与 565以及第一像素电极条纹 571、 572、 573与 574分别在区段 Α与区段 Β中分成第一部与第二部。也就是说,每一第二像素电极条纹与 每一第一像素电极条纹都是阶梯状的条纹。 在区段 A与区段 B的每一区段中, 第二像素 电极条纹 561、 562、 563、 564与 565以及第一像素电极条纹 571、 572、 573与 574沿相 同的方向延伸, 但是由于第一像素电极条纹与第二像素电极条纹的不连续结构, 针对相邻 的第一像素电极条纹与第二像素电极条纹来说, 区段 A 中每一电极间距的宽度与区段 B 中每一电极间距的宽度不同。 因此, 由上述多个邻近的第一像素电极条纹与第二像素电极 条纹所定义的八个电极间距之中的每一电极间距,在两区段中沿邻近的第一像素电极条纹 与第二像素电极条纹之间的参考线 (未示出)的延伸方向会具有变化的宽度。 也就是说, 每 一电极间距沿邻近的第一像素电极条纹与第二像素电极条纹之间的参考线的延伸方向不 连续变化。 对每一第一像素电极条纹 571、 572、 573与 574而言, 第一像素电极条纹在区 段 A与区段 B中的第一部以及第二部通过倾斜部 S相互连接, 如此第一像素电极条纹为
阶梯状条纹。 对每一第二像素电极条纹 561、 562、 563、 564与 565而言, 第二像素电极 条纹在区段 A与区段 B中的第一部与第二部也通过倾斜部 S连接, 如此第二像素电极条 纹为阶梯状条纹。 因此, 在电极结构的每一剖面中, 且在不同区段中, 每一电极间距之间 的电极间距比会不同, 且由于在不同的区段中, 电极间距为不同, 因此液晶显示装置的灰 阶伽玛曲线可以最佳化。
如图 5B所示, 在一替代实施方式中, 第二像素电极 560具有多个第二像素电极条纹 561、 562、 563、 564与 565。第一像素电极 570具有多个第一像素电极条纹 571、 572、 573 与 574。此外, 第二像素电极条纹 561、 562、 563、 564与 565以及第一像素电极条纹 571、 572、 573与 574区分至区段 A与区段 B中。 在区段 A中, 第二像素电极条纹 561、 562、 563、 564与 565以及第一像素电极条纹 571、 572、 573与 574沿第一方向延伸。然而在区 段 B中, 第一像素电极条纹 571、 572、 573与 574沿第二方向延伸, 而第二像素电极条纹 561、 562、 563、 564与 565 沿第三方向延伸, 形成介于第一方向与第二方向之间的锐角 θ!以及介于第一方向与第三方向之间的锐角 θ2。 因此, 由邻近的第一像素电极条纹与第 二像素电极条纹所定义的八个电极间距中的每一电极间距,在区段 Α中沿邻近的第一像素 电极条纹与第二像素电极条纹之间的参考线的延伸方向而具有均匀的宽度,而每一电极间 距在区段 B 中沿邻近的第一像素电极条纹与第二像素电极条纹之间的参考线的延伸方向 而具有变化的宽度。 因此, 在不同电极结构的剖面中, 每一电极间距的电极间距比在区段 A中会均一, 但在区段 B中则会相异。 由于在不同区段中沿电极条纹不同的电极间距, 因 此液晶显示装置的灰阶伽玛曲线可以最佳化。
本领域技术人员当知, 虽然图 2至图 5B所示的电极结构具有对称的电极条纹构造, 但是电极条纹也可以错位, 借此可以增加电极间距的多样性。 举例来说, 图 6A与图 6B 示出另二实施方式的液晶显示装置的交错电极结构。
如图 6A所示, 第二像素电极 660在图面上侧具有多个第二像素电极条纹 661、 662、 663与 664, 且在图面下侧具有多个第二像素电极条纹 665、 666、 667与 668, 而第一像素 电极 670在图面上侧具有多个第一像素电极条纹 671、 672与 673,且在图面下侧具有多个 第一像素电极条纹 675、 676与 677。所有第一像素电极条纹与第二像素电极条纹均彼此不 等距, 且位于图面上侧的第一像素电极条纹 671、 672与 673与位于图面下侧的第一像素 电极条纹 675、 676与 677彼此错位。 此外, 所有第一像素电极条纹与第二像素电极条纹 均区分至区段 A与区段 B中。 在区段 A与区段 B的每一区段中, 第一像素电极条纹与第 二像素电极条纹均沿相同的方向延伸,但是由于第一像素电极条纹与第二像素电极条纹的 不连续的结构, 因此在区段 A中每一电极间距的宽度与区段 B中每一电极间距的宽度不 同, 上述的每一电极间距为介于邻近的第一像素电极条纹与第二像素电极条纹之间的距 离。 如图 6A所示, 虽然电极结构只具有十二个电极间距 (图面上每侧各六个), 但是由邻 近的第一像素电极条纹与第二像素电极条纹所定义的每一电极间距,在两区段中沿邻近的 第一像素电极条纹与第二像素电极条纹之间的参考线的延伸方向而具有变化的宽度,且每
一电极间距的宽度会彼此不同。 由于沿邻近的电极条纹之间具有一多变电极间距, 且介于 上述多个电极条纹之间的上述多个电极间距具有不同宽度, 因此液晶显示装置的灰阶伽玛 曲线可以最佳化。
同样的,如图 6B所示。第二像素电极 660在图面上侧具有多个第二像素电极条纹 661、 662、 663与 664, 且在图面下侧具有多个第二像素电极条纹 665、 666、 667与 668, 而第 一像素电极 670在图面上侧具有多个第一像素电极条纹 671、 672与 673,且在图面下侧具 有多个第一像素电极条纹 675、 676与 677。所有第二像素电极条纹与第一像素电极条纹均 彼此不等距, 且位于图面上侧的第一像素电极条纹 671、 672及 673与位于图面下侧的第 一像素电极条纹 675、 676及 677彼此错位。 此外, 所有第二像素电极条纹与第一像素电 极条纹均区分至区段 A与区段 B中。 在区段 A中, 第一像素电极条纹与第二像素电极条 纹在图面的相同侧皆沿相同的方向延伸。然而, 在区段 B中, 第一像素电极条纹和第二像 素电极条纹, 相较于区段 A中的电极条纹, 将沿不同的方向延伸。 如图 6B所示, 虽然电 极结构只具有十二个电极间距 (图面上每侧各六个), 但是由邻近的第一像素电极条纹与第 二像素电极条纹所定义的每一电极间距,其位在区段 A中邻近的第一像素电极条纹与第二 像素电极条纹之间会具有均匀的宽度,而其位在区段 B中邻近的第一像素电极条纹与第二 像素电极条纹之间会具有变化的宽度, 且每一电极间距的宽度会彼此不同。 如此一来, 由 于邻近的电极条纹间的电极间距具有多变的宽度,且介于上述多个电极条纹之间的上述多 个电极间距具有不同宽度, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。
图 2至图 6B所公开的实施方式可经由任何实施方式的组合来了解。举例来说, 图 7A 与图 7B所示的第一像素电极 770结构的两实施方式, 其中第二像素电极 760的所有第二 像素电极条纹与第一像素电极 770的所有第一像素电极条纹均彼此不等距,且所有第二像 素电极条纹与所有第一像素电极条纹均区分至三区段 A、 B与 C中。
如图 7A所示, 在区段 A与区段 C中, 第二像素电极条纹 761、 762、 763以及 764与 第一像素电极条纹 771、 772以及 773皆沿相同的方向延伸。 然而, 在区段 B中, 第一像 素电极条纹 771、 772以及 773与第二像素电极条纹 761、 762、 763以及 764, 相较于区段 A以及区段 C中的电极条纹, 将沿不同的方向延伸。 图 7B的电极结构与图 7A的结构为 实质上相似的结构, 而差异存在于位于图面上侧的第一像素电极条纹 771、 772 以及 773 与位于图面下侧的第一像素电极条纹 775、 776以及 777彼此错位。 在本实施方式中, 每 一第二像素电极条纹 761、 762、 763、 764、 765、 766、 767、 768与第一像素电极条纹 771、 772、 773、 775、 776与 777皆为曲线条纹或斜条纹。 如图 7A与图 7B所示, 虽然电极结 构只具有十二个电极间距 (图面上每侧各六个), 但是由邻近的第一像素电极条纹与第二像 素电极条纹所定义的每一电极间距,在三个区段中沿邻近的第一像素电极条纹与第二像素 电极条纹之间的参考线 (未示出)的延伸方向而具有变化的宽度, 且每一电极间距的宽度会 彼此不同。 如此一来, 由于沿邻近的电极条纹的多变电极间距, 与介于电极条纹之间的不 同电极间距, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。 本领域技术人员当知, 虽然
图 2至图 7B所示的实施方式均具有垂直式电极结构, 但是本发明可应用于任何形式的电 极结构。 举例来说, 图 8A与图 8B示出第一像素电极结构的两实施方式, 其中第二像素 电极 860与第一像素电极 870设置在水平电极结构中。 如图 8A与图 8B所示, 第二像素 电极 860具有多个第二像素电极条纹, 例如 861-868与 861a-868a。 第一像素电极 870具 有多个第一像素电极条纹,例如 871-878与 871a-878a。这些第二像素电极条纹 861-868和 861a-868a与第一像素电极条纹 871-878和 871a-878a交错设置,借此定义其间的多个电极 间距, 其中每一电极间距由两邻近的第一像素电极条纹与第二像素电极条纹所定义。第一 像素电极 870也具有侧部 879b与脊部 879。 脊部 879自侧部 879b垂直延伸。 此外, 每一 第一像素电极条纹自侧部 879b与脊部 879其中之一延伸, 借此每一第一像素电极条纹与 脊部 879定义一第一角度 ocl于其间。 在本例示性实施方式中, 侧部 879b以及第一像素电 极条纹 871-878与 871a-878a对称于脊部 879形成。 此外, 第二像素电极 860还具有侧部 869b, 顶部 869与底部 869a。 此侧部 869b具有第一末端与第二末端。 此第二末端与第一 末端相对。 顶部 869与底部 869a分别自侧部 869b的第一末端与第二末端垂直延伸。 此第 二像素电极 860的侧部 869b与第一像素电极 870的侧部 879b平行对齐。在本例中, 每一 第二像素电极条纹自侧部 869b、 顶部 869与底部 869a其中之一朝向第一像素电极 870的 脊部 879延伸,借此每一第二像素电极条纹与第一像素电极 870的脊部 879定义一第二角 度 0C2于其间。对此例而言,顶部 869、底部 869a、侧部 869b以及第二像素电极条纹 861-868 与 861a-868a对称于第一像素电极 870的脊部 879设置。 图 8A所示出的电极结构与图 2 所示出的电极结构相似, 其中所有第二像素电极条纹 861-868与 861a-868a以及第一像素 电极条纹 871-878与 871a-878a平行设置, 且电极间距的宽度不同。 在本例示性实施方式 中, 第一角度 ocl与第二角度 oc2相同。 图 8B所示出的电极结构与图 3A所示出的电极结构 相似, 其中第二像素电极条纹 861-868与 861a-868a沿一方向延伸, 而第一像素电极条纹 871-878与 871a-878a沿一不同的方向延伸。 也就是说, 第一角度 ocl与第二角度 oc2实质上 不相同, 借此定义多个电极间距, 这些电极间距沿邻近的第二像素电极条纹与第一像素电 极条纹之间的参考线的延伸方向, 具有变化的宽度。
在另一实施方式中, 可将第一像素电极条纹与第二像素电极条纹分成多个不同的区 段, 在每一区段中, 每一电极间距的宽度可沿邻近的第一像素电极条纹与第二像素电极条 纹之间的参考线的延伸方向有不同的变化。如图 9所示, 第一像素电极 970具有多个第一 像素电极条纹 971、 972与 973。第二像素电极 960具有多个第二像素电极条纹 961与 962。 在本实施例中,相邻的第一像素电极条纹与第二像素电极条纹是相对于其间的参考线而呈 现镜向结构 (或对称)。 此外, 第一像素电极条纹 971、 972与 973 以及第二像素电极条纹 961、 962分别在区段 A、 B、 C及 D中分成第一部、 第二部、 第三部以及第四部。 也就是 说, 每一第一像素电极条纹与每一第二像素电极条纹都是锯齿状的条纹。 因此, 由邻近的 第一像素电极条纹与第二像素电极条纹所定义的四个电极间距中的每一电极间距,在区段 A、 B、 C及 D中都会具有不同变化的宽度。 举例来说, 对于由第一像素电极条纹 971与
第二像素电极条纹 961所定义的电极间距而言,在区段 A中电极间距的宽度将由图面的上 方至下方渐减, 在区段 B中电极间距的宽度将由图面的上方至下方渐增, 在区段 C中电 极间距的宽度将由图面的上方至下方渐减,在区段 D中电极间距的宽度将由图面的上方至 下方渐增。 由于在不同区段中沿电极条纹之间的参考线的延伸方向有不同变化的电极间 距, 因此液晶显示装置的灰阶伽玛曲线可以最佳化。
图 2至图 9所示出的第一像素电极结构的实施方式, 可以应用于图 1A与图 1B所示 出的垂直配向-横向电场效应的结构, 或横曲配向的结构中。 图 10A与图 10B示出依据本 发明一实施方式的液晶显示装置 1000的两局部剖面图。 图 10A示出当未对液晶显示装置 1000施加电压时的液晶的方向, 而图 10B示出当对液晶显示装置 1000施加电压时的液晶 的方向。依据本实施方式, 液晶显示装置 1000利用横曲配向的技术, 并包含与图 1A与图 1B的液晶显示装置 100相似的元件。 在图 10A与图 10B中, 唯一的差异存在于每一像素 还包含对向电极 1080。此对向电极 1080形成于第二基材 1020上。在一实施方式中, 对向 电极 1080电性连接第二像素电极, 如此当施加电压时, 对向电极 1080以及第二像素电极 条纹 1062、 1063与 1064会被施加相同的电压 Vcom。 在本发明另一实施方式中, 对向电 极 1080电性连接第一像素电极, 如此当施加电压时, 对向电极 1080以及第一像素电极条 纹 1072与 1073会被施加相同的电压 Vcom。 在本发明的再一实施方式中, 对向电极 1080 会被施加交流电压或直流电压。 依据图 10A与图 10B所示出的实施方式, 液晶显示装置 的其他元件, 例如: 液晶层 1030、 液晶 1032、 绝缘层 1040与保护层 1050以及其他特征, 与图 1A与图 1B所示出的实施方式中的液晶显示装置实质上相同。
在一实施方式中, 当将交流电压或直流电压施加于第二像素电极的同时, 将交流电压 施加于第一像素电极。在另一实施方式中, 当将交流电压或直流电压施加于第一像素电极 的同时, 将交流电压施加于第二像素电极。
本领域技术人员当知,前述实施方式可应用于任意形式的液晶显示装置或带有不同像 素配列的面板。举例来说, 图 11A示出一实施方式的液晶显示装置的像素配列, 其中每一 像素包含如以上所公开的垂直像素结构 1110, 例如: 如上述图 2至图 7B所公开的。
如图 11A所示, 像素配列具有多个垂直像素结构 1110。 多个栅极线 1120电性连接垂 直像素结构 1110, 而为了控制每一像素的驱动信号, 多个信号线 1130电性连接垂直像素 结构 1110。此外,每一垂直像素结构 1110具有薄膜晶体管 1040(Thin-film transistor; TFT)。 薄膜晶体管 1140作为驱动装置, 借此控制通过对应的栅极线 1140与对应的信号线 1130, 供应给垂直像素结构 1110的第一电极与第二电极的电压。 图 11B示出例示性垂直像素结 构 1110, 此垂直像素结构 1110电性连接栅极线 1120与信号线 1130。 在本例中, 每一第 一像素电极条纹 1171与栅极线 1120其中之一形成第一角度 ccl。而每一第二像素电极条纹 1161与栅极线 1120其中的该一个形成第二角度 oc2。 第一角度 ocl与第二角度 oc2可以相同 或是实质上不同。 在图 11B所示的本例中, ocl = oc2。
任何其他像素结构,若可应用在液晶显示装置或面板中,也可应用本发明的电极结构。
举例来说, 图 12A与图 12B示出位于液晶显示装置内的水平像素结构的像素配列, 其中 每一像素包含如以上所公开的水平像素结构 1210,例如: 如上述图 8A与图 8B所公开的。 同样的,多个栅极线 1220电性连接水平像素结构 1210,且为了控制每一水平像素结构 1210 的驱动信号,多个信号线 1230电性连接水平像素结构 1210。此外,每一水平像素结构 1210 具有薄膜晶体管 1240。薄膜晶体管 1240作为驱动装置,借此控制通过栅极线 1220与信号 线 1230,供应给水平像素结构 1210的电极的电压。图 12B示出例示性水平像素结构 1210, 此水平像素结构 1210电性连接对应的栅极线 1220与对应的信号线 1230。 在图 12B所示 的本例中, 每一第一像素电极条纹 1270与栅极线 1220其中之一形成第一角度 ocl。而每一 第二像素电极条纹 1261与栅极线 1220其中的该一个形成第二角度 oc2。 第一角度 ocl与第 二角度 0C2可以相同或是实质上不同。 如图 12B所示的本例中, ocl ≠ o2。
总结来说, 本发明, 除了其他方面, 提到液晶显示装置包含像素阵列。 此像素阵列具 有多个像素。每一像素包含第一像素电极与第二像素电极。第一像素电极具有多个第一像 素电极条纹。第二像素电极具有多个第二像素电极条纹。第一像素电极条纹与第二像素电 极条纹交错设置, 借此定义多个电极间距于其间。每一电极间距定义为介于两邻近的第一 像素电极条纹与第二像素电极条纹之间, 并具有宽度。 电极间距其中至少一个的宽度与其 他电极间距的宽度不同。此外, 每一电极间距的宽度沿邻近的第一像素电极条纹与第二像 素电极条纹之间的参考线的延伸方向而变化。由于邻近的电极条纹间的电极间距具有多变 宽度, 且介于上述多个电极条纹之间的上述多个电极间距具有不同宽度, 因此液晶显示装 置的灰阶伽玛曲线可以最佳化。
在上述所示的实施方式中, 每一像素还可包含对向电极。此对向电极形成于第二基材 上, 并电性连接第二像素电极或第一电极。 或者, 对向电极也可电性连接交流电压或直流 电压。
先前介绍本发明例示性实施方式仅为示意与描述的目的, 并非做全面性的描述, 或意 欲确实地将本发明限制在所公开的形式。 鉴于上述的教导, 许多的修改与变化是可能的。
为解释本发明的原理及其实际应用,借此使本领域技术人员积极利用本发明及其多样 的实施方式, 伴随在经思虑的特定用途上的多样修改, 选出这些实施方式并加以描述。 对 于习知本发明所属技术而不脱离其精神与范围的本领域技术人员而言,替代性实施方式将 是清楚的。 因此本发明的保护范围当视所附的权利要求所界定的范围为准, 而非之前的描 述及其中所述的例示性实施方式。
