( F腿 Out ) 91展幵到适当位置后再进入显示区 92« 从围 1中可 见, 在展开区 91中, 与显示驅动芯片 1中心的榆 ώ端口相连的 Ϊ 动线 71最短、 而与显示骡动芯片 1两端的输 Λ端口相连的 动 71最长; 各条氧动幾 71位于辰开区 91 中的部分的长度的差别会 I致各条驅动线 71的总长度(各条骡动线 71在显示区 92中的长 度一般相等)不同,从而导致各条驅动线 71的总电且值(&抗值) 不同, 即各输出端口对应的 抗不匹配; 而 抗不匹配会导致 Vertical Block Mura (竖条污 Ife ) , Horizontal Block Mura (横条污 染) 、 区域色偏等不良, 从而影响显示质量

优选的, 所迷显示装置为液晶 示装置或有机发光二极管显 示装置。 本发 可用于采用有 驅动陣列的显示装置中, 倒如波晶显 示装置、 有机发光二极管显示装置等; 且其特则适用于采用窄逸 框、 精 三橋、 高频 ¾动等技术的显 装置 附图说明

其中附围标记为: I、 显示 动芯片; I 1、 动电路; 21、 芯 片且 匹配阜元; 22、 连接錢JL抗匹配单元; 71 , 动戴; 72、 连接线; 8 K 柔性錢路 ; 82、 印刷线路 ; 9、 陴列基板; 91、 , 开区; 92、 显示区《 具体实施方式
为使本领域技术人员更好地理解本发明的技术方案, T面结 合附围和具体实施方式对本发 作遞一步详细描述„ 实施例 1 :
如 S 2 所示, 本实施例提供一种显示氧动芯片 1 , 其可为用 于 动 *极幾的栅极氧动芯片 ( Gate Driver IC ) , 也可为用于 ® 动数 *线的数振 ϊ动芯片 ( Data Driver IC )等其他类型的显示夏 动芯片。
显示職动芯片 1 具有多个输 ώ端口, 每个输 ώ端口用予连接 —根暴动线 71 (翁如栅极线、 数椐线或公共电挺线等, 且包括位 予展开区 91 中的部分和位予显示区 92中的部分) 并为其提供 «I 动信号。 显示驅动芯片 1 的输 ώ ¾ σ的数量通常为数十个至数 ¥ 个, 具体可根据其 ¾号决定„
如 Β 2所示, 本实 例的显示 动芯片 1设在印剧载路权 82 上, 而印 线路极 82通过柔性线路极 81与障列基权 9连接, 显 示暴动芯片 1 的各输出 口通过印剧线路极 2和柔性线路权 81 上的连接线 72与騍动线 71相连。
当然,显示 动芯片 1也可设在柔性线珞极 81上而形威覆晶 薄膜, 并通过柔性幾路 81上的连接线 72与驱动线 71相连; 或 者, 显示驅动芯片 1也可直接设在陣列基极 9上, 此时不需要连 接线 72, 其输 ώ端口直接与驱动载 71相连^可
显示驱动芯片 〗 内部设有用于产生 ¾动信号的 动电珞 11, 2动电路 11连接至各输出端口; 也就是说, 显示 动芯片 1可通 it内部的霍动电路 1 1将束自显卡等的显示信号转换为多个 Φ动信 号, 并将这些驅动信号分则鍮出到各个榆出端口, 透而 Φ动各条 动线 71。
其中,至少一个输出 ¾口与驅动电路 1 1间设有具有一定阻 值的阻 配单元 (芯 if F且抗匹配举元 21 ) e 也就是 , 在显示 动芯片 i的内部还设有芯片 匹配单元 21, 芯片 F且抗 配 羊元 21设于驅动电路 11 与输 ώ端 σ之间, 且其阻抗值相对于 动线 71的阻抗值而言足够大。
如 S 2所示, 与同一个显示驅动芯片 〗相连的多根 动线 71 在展开区 91 中的部分长度不同, 故各 动线 71 总长度不同, 其 电抗值(主要为电 &值)也不同; 由于通常各条连接线 72长度相 同而JL抗值相等, 故连接在每个榆出端口上的总 EE抗值 (或者 ¾ 对应每个 Ϊ动信号的总阻抗值) 不同, 这会 多种显示不良, 降低显 廣量。
为此, 本实施倒的显示驅动芯片 1 中针对每个输出端 增设
T芯片阻抗匹配单元 21 ,各芯片 &抗匹配单元 2 1连接在 ώ ¾口 与 动电路 11之间, 故到达每个输 ώ端口的 动信号都要先经过 芯片 JL抗 β配单元 21 ,即芯片 Jfi抗匹配单元 2 1会对駆动信号起作 用, 固此芯片 抗 fi 季元 21成为输出端口所连接的&抗的一部 分。 这样, 只要周节各芯片 JL抗匹配单元 21的 抗值, 即可改变 各输 口所连接的且抗值, 也就可以实现各输 Λ 口的JL抗匹 配, 改善显示盾量。
而且, 当显示装置采用窄迹框设计时, 展开区 91的宽度需要 被尽量縮小; 而辰开区 91 的宽度越小, 則其 的氧动线 71就越 "傾斜 " , 各《动线 71间的长度差 ft越大, JL抗不 &配的问题就 越严重, 故这限制了辰开区 91的尺寸, 也就 得了 逸輕设讦的 实现 由于本实 例的显示 动芯片 1 中具有芯片 J E S己季 元 21, 敌可通过调整芯片阻抗匹配单元 21实现阻抗匹配, 因此在 缩小展开区 1 宽度时不必考虑阻抗匹配问题, 故其易于实现显示 装置的窄速極设计
优遶的, 在从显示霍动芯片 1 中心到两端的方向上, 各输出 端口所连接的芯片阻抗匹配羊元 21的阻抗值遲渐减小 β
如¾ 2所示, 在从显示驅动芯片 1 中心到两端的方向上, 与 各输 ώ端口相连的 «动线 71的长庹是遷: 增加的, 即其 F且抗值是 遲漸増加的, 故为了使与各输出端口对应的阻抗匹配, 则在从显 示駔动芯片 1 中心到两¾的方向上, 分别与各输 ώ端口相连的各 芯片 抗; S配单元 21的 I5L抗值优遶是遲渐减小的„
优逸的, 针对显示 S动芯片 1 的每个输出¾口, (Ζζ¾ ) 值相等, 其+, ζζ1为与一个 应输 ώ端口连接的芯玲 f 抗 Ε 单 元 21 的 i抗值, Z¾为与《相应输出端口连接的霍动幾 71 的&抗 值; 其中, Zq是指 S 线 7 1 整体 (包括位于展开区 91 中的部分 和位于显示区 92 中的部分) 的JL抗值, 当然 Zq的不同通常是由 Ϊ动线 7 1在展开区 91 中的部分引起的,各駆动线 71在显示区 92 中的部分的阻抗值通常相等, 粗应当理解, 如果各霍动 71在显 示区 92中的部分的阻抗值不同, 也可使用上迷方法一起补襟
显然》 为了达到最 的 抗匹配效杲, 遶应 使每个翁 端口对 的 抗值都相等。 而由予与各输出端 σ相连的连接幾 72 的阻抗值一般是相等的 (甚至可能根本没有连接线) , 故只要与 每个输 ώ端口相对应的芯片 抗匹 fi 羊元 21的 抗值和对应«动 线 71 的 &抗值之和相等, 即可实现最优的 JL抗匹配。
优选的, 芯片 抗 配单元 21 括电 PE单元, 电容单元、 电 感单元中的任意一种或多
式为
Figure imgf000010_0001
其中, R为电 Pi值, L为电感值, C为电容值, ω为交流电的 角频率。 也就是说, !fi抗被与交 电路中的电且、 电容、 电感、 交流电频率相关, 由予对于同一显示驅动芯片 1 而言, 其 ω值是 相同 JL不可隨意改变的, 故可通过设置电& »件 电容器件、 电 感器件申的任意一个或多个来改变其 抗偟 (即显示 Ϊ动芯片 1 作为芯片 ί且抗匹配羊元 21 ) «
其中, 芯片阻抗匹配羊元 21 更优遶包括电且单元或电容羊 元 这是由于在集成电路中设置电感单元比较國难, 且其可能对 电路的其他性能产生影 , 故优选以电 &举元或电容单元作为芯 片 p且 匹配举元 21 a
进一歩^逸的, 电置单元为 载。 也就是说, 可直接增设不 同长度的导载作为电「Λ羊元, 这是因为导幾本身即具有电JL , 且 其电&值与导线长度成正比。 例如, 可在原有的显示 ¾动芯片 1 中增设金属. , 并在金属层上形成连接在騍动电踏 1 1和繪 ώ端口 间的导线, 通过一定的布幾设 , 可很容易的使连接不同输 Λ端 口的导线具有不同的 度以提供所需的电阻值 (电抗值) , 实现 各输 ώ端口的 配 最 单的, 可在 S动电路 1 1和输 ώ端口 同设置一段戴多段波浪线状的导线, 且越靠近显示 动芯片 1 中 心、的 ilr 端口连接的波浪线长度越大或段数越多, 而越靠近星示 4 动芯片 1 两端的输 ώ端口连接的波浪线长度越短或段数越少, 而显示驅动芯片 I 两^的输 tt{端口则可不连接波浪线 (即没有芯 片 抗 配单元 21,或也可将 Ϊ动电路 1 1与偷 ¾端口间的皇錢导 我看作&抗值很低的芯片且抗匹配单元 2 1 ),从而实现 EE抗匹囊& 当然, 使用电 阜元作为芯片阻抗匹配单元 21也是可行的; 例如, 可在显示 Ϊ动芯片 1 中的两相邻 中分别设置相对应的金 属片, 再将两个金属片分则连接 线, 则两个金属片即构成电容 结构 β
应当理解, 虽然以上是以导线 电容单元作为芯片阻 匹配 单元 21的例子, 但只要能实现 抗匹配的目标, 使用其他结构作 为芯片 JL抗匹配单元 21也是可行的; 例如, 也可用电 ΙΙ作为芯 片 |¾抗 ES配車元 21 ; 或者, 也可用电感单元作为芯片 J ffi S己季 元 21 ; 或者, 也可用 "导 +电容单元 M 作为芯片阻抗匹配单元 21 等
总之, 本实施例中芯片 EE抗 配单元 21的设置 (包括在哪些 榆 ώ端口设置、 芯片 J t匹 g£羊元 21的类 芯片且抗匹配单元 21的 &抗值等)可根振駆动线 71的布线情况具体设置, 以上所举 的只是其部分例子, ·ί旦只要显示驱动芯片 1 中设有芯片 F且抗 Ε配 单元 21, 其即屬于本发明的保护范围。 实 ^例 2:
如图 3所示, 本实 例提供了一种显示駔动芯片組件, 其 括显示氧动芯片 1和桑性幾踡权 81, 显示驅动芯片 1 包括多个 榆 端口, 各偷出端口与柔性錢路 81上的各连接錢 72相连, 而各连接载 72用于连接各 动幾 71。
优选的, ¾ 示 动芯片 1可直接设在 性线 权 81上, 也 就是显示驅动芯片組件优逸为覆晶薄膜。 此时显示 动芯片 1 的 各繪出端口 直接通这桑性线路极 81上的连接线 72与陣列基板 9 上的各驅动幾 71相连。
当然, 显示驅动芯片 〗也可设在印刷线路极 82上, 而印刷线 路极 82再遷过柔性线路权 81连接至阵列基抵 9,
同时, 柔性线路极 81上的至少一根连接线 72 设有具有一 定 &抗值的连接线 抗匹配单元 22„ 也就是说, 本实 fe倒的显示 ¾动芯片 件与以上实 fe倒的显示驅动芯片 1 类似, 其中都设有 连接幾JL抗 ffi配单元 22以调整与各输 ώ端口对应的 &抗值, 实现 HE 匹配, 改善显示质量 与上述实施例不同的是, 本实 fe例中的阻抗匹配举元不是设 于显示騍动芯片 1 内部, 而是设于柔性线路极 81的连接錢 72上, 即其为连接线 F且抗匹配車元 22; 显然, 这样的连接线 抗匹 fc单 元 22也可实现阻抗匹配的目的。
而且, 芯片中集.咸电路的设计 制造过程均是比较复杂的, 因此, 要改变现有显示«动芯片 1 的结构, 在其中 设芯片 &抗 匹配单元 21 的工艺难度较大, 成本高; 相对的, 在柔性线路板 81 上设置电路或 II件的技术难度低 同时, 柔性錢路权 81上的空间 显然比芯片内部大得多, 因此若在其上设置连接线 ia抗匹 单元
22 , 则其在器件逸 #、 布线设计等方 都有更大的自由度。 因此, 与上迷实 例相比, 本实 fe例的方案更易于实现, 成本更低。
优逸的, 本实 例的显示驅动芯片 旦件中使用的显示 区动芯 片 i也可为上述实 例 1 申的显 驱动芯片 I .也就是说,显示 动芯片 i申也可具有芯片阻抗匹配单元 21 , 从而通过芯片阻抗匹 配羊元 21和连接錢阻抗匹配单元 22的共 作用实现 |¾抗匹配 显然,显示 ¾动芯片 1中的芯片且抗匹配单元 21和桑性幾路 板 81 中的连接 F 拔匹配举元 22的组合可以是任意透行的: 例 如可对某些霍动载 7 1只使用连接线 &抗匹配单元 22透行调节, 对其余的 S动线 7 1 只使用芯片 JL抗匹配单元 2 1透行调节; 或者 也可对同一条驅动线 71 ' 在显示霍动芯片 1 中和喿性幾路板 8 1 中都分别设置相应的芯片且抗匹配单元 21和连接錢且抗 21 单元 22以共 对其透行阻抗调节。
显然, 应当理解, 当同时具有显示驅动芯片 1 的芯片阻抗 匹配单元 21和桑性线路极 81中的连接线阻抗匹配单元 22时, 与 显示暴动芯片 〗的每个揄 Λ端口相对应的各 抗值 ( Zz3+Zq )优遶 仍然是相等的;且 Λ时 Zz3为与一个相应繪出端口连接的全部JL抗 匹配单元 (包括芯片 &抗匹配单元 21和连接线阻抗 IS配单元 22 ) 的 &抗值之和。 实施 ] 3:
本实 fe例还提供了一种显示装置, 其包括上述的显 动芯 片或显示驱动芯片組件
优选的, 本实^例的显示装置为液晶显示装置或有机发光二 植管显示装置。 具体的, 本实施例的显示装置可为电子紙, 手机、 平极电脑 电視机、 显示 , 笔记本电脑、 数码相裰、 导航仪等 任何具有显示 1 的产品或部件
当然, 显示装置申还.应包括其他的已知结构, 如阵列基权、 背光源、 彩膜基权, 封装基板、 电源、 裡架等
由亍本实; ife例的显示装置包括上述的显示 ¾动芯片或显示 Ϊ 动芯片 件, 故其可消除由阻抗不匹配引起的显示不良, 提高显 示盾量, 且易亍实现窄途框设计《 可以理解的是, 以上实施方式仅 ·叉是为了 明本发明的原理 而采用的 例性实施方式, 然而本复明并不局限于此 β 对于本領 城内的普通技术人员而言, 在不 IC离本发明的精 和实 的情况 下, 可以做 各种变型和改透, 这些变 和改透也視为本发明的 保护范围。
