需要说明的是,本文中涉及到的"像素结构"包括多个子像素, 且各个子像素被分别配 置在由多条数据线和多条扫描线交错形成的多个子像素区中。 在该实施例中, 所谓"子像 素"可以为红色(R )子像素、 绿色(G )子像素或蓝色(B )子像素等不同颜色的子像素。
请参考图 3 , 图 3是根据本发明一实施例的子像素的结构示意图。 该子像素应用于图 2所示的显示面板中。 如图 3所示, 该子像素包括第一显示区 (也称为 Main区) 、 第二 显示区 (也称为 Sub区) 和第三显示区 (也称为 Share区) 。 Mam区配置以接收第一扫 描线的扫描信号, 进而接收第一数据线上的数据信号而具有第一电位; Sub区配置以接收 第一扫描线的扫描信号,进而接收与第一数据线相邻的第二数据线的数据信号而具有与第 一电位不同的第二电位; Share区配置以接收与第一扫描线相邻的第二扫描线的扫描信号, 进而接收来自 Sub区的第二电位而具有第:三电位。
各个区中分别包含多个畴 (domam ) , 如图所示, 每个区被划分为四个畴, 其中, Data n用于向 Main区发送信号以控制 Main区, Data irH用于向 Sub区发送信号以控制 Sub区, Gate n控制 Main区和 Sub区, Gate n+l控制 Share区[:
请同时参照图 3及图 4, 来说明该子像素的整个结构组成。 图 4是根据图 3所示的子 像素的等效电路示意图。 子像素包括开关元件 (TFT__A、 TFT—B和 TFT _ C) 、 存储电容 ( CST...Main、 CST„.Sub和 CST.__ Share)以及液晶电容(CL ... Main、 CLc. Sub和 CLC— Share) 。 开关元件 TFT— A、 TFT— B和 TFT— C均优选以薄膜晶体管制作而成。
另外, 图 4所示的 CF—Com是指液晶显示的上板基准电位, 而 A__ com是指下板存在 电容的基准电位, 通常这两个电位是一致的, 可以统称为共同电极 VCOM。
以 Main区而言,开关元件 TFT A电性连接于数据线 Data ιι和一子像素电极 V— A之 间, 且其控制端 (極极) 电性连接扫描线 Gate ji, 存储电容 CST— Main则电性连接于子像 素电极 V—A与一共同电极 A—com之间,液晶电容 CLC Mam电性连接于子像素电极 V— A 与一共同电极 CF _.com之间。 当幵关元件 TFT— A幵启时, 数据线 Dataji上的数据信号经 由开关元件 TFT_ A传送至存储电容 CST__Mairiu 存储电容 CST._ Main则根据数据信号充电 而存储相应的电位, 基于此, 子像素电极 V„ A也具有相对应的电位, Mam区依据此显示 影像数据。
以 Sub区而言, 开关元件 TFT— B电性连接于数据线 Data— n+1和一子像素电极 V— B 之间, 且其控制端也电性连接扫描线 Gateji, 而存储电容 CST„Sub则电性连接于子像素 电极 V—B与一共同电极 A__ com之间, 液晶电容 Q.c― Sub电性连接于子像素电极 V—B与 一共同电极 CF„com之间。 当开关元件 TFT JB开启时, 数据线 上的数据信号经 由开关元件 TFT_ B传送至存储电容 CST.„Sub, 存储电容 CST.„Sub根据数据信号充电而存 储相应的电位, 且子像素电极 V—B也具有相应的电位, Su 区依此显示影像数据。
需要重点说明的是,对于 Share区来说,开关元件 TFT— C电性连接于子像素电极 V— B 和子像素电极 V— C之间 , 其控制端电性连接 描线 Gate— 1, 而存储电容 CST„ Share则 电性连接于子像素电极 V—C与一共同电极 A—com之间,液晶电容 CLC Share电性连接于 子像素电极 V„C与一共同电极 CF___.com之间。 当开关元件 TFT _C开启时, 子像素电极 V B的电位由开关元件 TFT—C传送至存储电容 CST._ Share,存储电容 CST_„Share存储相应 的电位, 旦子像素电极 V—C也具有相应的电位, Share区依此显示影像数据。 也就是说, 子像素电极 V— C的电位能够拉降子像素电极 V— B的电位, 或是子像素电极 V— C的电位 能够拉升子像素电极 V—B的电位。
下面参考图 5 (a) 和 (b) 分别说明在 2D显示和 3D显示时的各个区的具体驱动情 况以及子像素点电极所具电位的变化情况。 然, 图 5 Ca) 和 (b) 仅为示倒而已, 并非用
以限定本发明, 亦即在不脱离本发明的精神和范围内, 子像素电极 V„A、 V„B、 V _C的 电位变化可依据实际需求有所调整, 而图 5 (a) 和 (b) 所示的子像素电极 V„A、 V„B、 V .C;亦可概括地分别泛指 Main区、 Sub区和 Share区的电位变化。
在迸行 2D显示时, 概述地说是, 通过利用 Share区将 Sub 区的电位 (子像素电极 V. B) 拉低, 造成 Sub区和 Share区这两区的电位与 Main区形成一定的差异 Δν, 同时 利用 Main区和 Sub区的两条数据线(Dataji和 Data— n+1 )传递的数据信号(data signal) 来调控 ΔΥ, 实现较佳的 LCS效果。
具体地, 请同时参照图 4和图 5 (a) , 在正半周 (即极性反转中的正极性反转, 数 据信号电位大于共同电极 VCOM的电位) 期间, 当扫描线 Gate 在 tO和 tl之间传输扫 描信号 (输出高电平) 时, 开关元件 TFT— A和 TFT B根据扫描信号开启, 使得数据线 Data n和 Data—jr 1上的数据信号分别经由开关元件 TFT— A和 TFT— B传送至存储电容 CsT„ am和 CST„Sub, 存储电容 CST„Main和 CST— Sub則根据数据信号充电而存储相应的 电位, 致使子像素电极 V—A和 V—B据此具有相对应的电位。 需要注意的是, 此时 Sub区 与 Mam区具有一定的电压差 ΔΥ。 并且, 利用数据线 Mam区和 Sub区的数据线 Dataji 和 Data_n+〗可以调控电压差 ΔΥ的大小。
接着, 当扫描线 Gatej H在时间 tl和 t2之间传送扫描信号 (输出高电平) 时, 开 关元件 TFT— C根据扫描信号开启, 使得子像素电极 V„ B经 ffl开关元件 TFT— C传送至存 储电容 CST— Share, 存储电容 CST„ Share则充电而存储相应的电位, 致使子像素电极 V—C 据此具有相对应的电位。 此时 Share区与 Sub区的电压一致, 均与 Main区形成相同的电 压差 Δν。
相反地,于负半周(即极性反转中的负极性反转,数据信号电位小于共同电极 VCOM 的电位)期间, 当扫描线 Gateji在时间 t3和 ί4之间传送扫描线信号时, 开关元件 TFT_A 和 TFT_ B根据 描信号开启 ' 使得数据线 Dataji和 Da ij l上的数据信号分别经由开 关元件 TFT_ A和 TFT_ B传送至存储电容 CST__ Main和 CST__ Sub, 存储电容 CST__ Main和 CST„Sub则根据数据信号充电而存储相应的电位, 致使子像素电极 V— A和 V— B据此具有 相对应的电位。 需要注意的是, 此时 Sub区与 Main区具有一定的电压差 Δν。
接着, 当扫描线 Gate— η十】在时间 t4和 t5之间传送扫描信号时, 开关元件 TFT— C根 据扫描信号开启,使得子像素电极 V_ B经由开关元件 TFT_ C传送至存储电容 CST._ Share, 存储电容 CST„Share则充电而存储相应的电位, 致使子像素电极 V„C据此具有相对应的
电位。 此时 Share区与 Sub区的电压一致, 均与 Main区形成相同的电压差 Δν。
如此一来, 无论在正极性反转或负极性反转的操作, Main区与 Sub区和 Share区之 间有显著的电位差异, 并且 Su 区与 Share区之间的电位具有延迟, 使得这三个区所显示 的影像彼此间能够有较为显著的区别, 因此能够有效地解决在 2D显示时显示器具有色偏 的问题。
在进行 3D显示时, 概述地说是, 首先利 插黑的方式将 Share区形成黑色区域, 然 后关闭该区的扫描信号(Gate信号) , 使其保持暗态, 这样就形成了 3D FPR显示所需的 较宽间距。 最后, 再利用 Main区和 Sub区的两条数据线 (Data— n和 Data— n+1 ) 传递的 数据信号 (data signal ) 来实现 3D的 LCS效果。
由于事先使 ^插黑的方式将 Share区形成了黑色区域, 并且关闭了该区的扫描信号, 因而形成了 3D__FPR显示所需的较宽间距, 如图 6所示。
具体地, 请参照图 4和图 5 ( b ) , 在正半周 (即极性反转中的正极性反转, 数据信 号电位大于共同电极 VCOM:的电位) 期间, 当扫描线 Gate—n在 t0和 tl之间传输扫描信 号曰 开关元件 TFT— A和 TFT— B根据扫描信号开启, 使得数据线 Data__n和 Data_n+1上 的数据信号分别经由开关元件 TFT _A和 TFT— B传送至存储电容 CST— Main和 CS1— Sub, 存储电容 Csi—Mam和 CST__Siib则根据数据信号充电而存储相应的电位, 致使子像素电极 V— A和 V— B据此具有相对应的电位。 需要注意的是, 此时 Sub区与 Main区具有一定的 电压差 Δν。
接着, 当扫描线 Gate__n+1在时间 tl和 t2之间传送扫描信号时, 由于关闭了 Share区 的扫描信号, 因此该区的电极 V— C的电位与共同电极 VCOM的相同, 视为 0。
相反地, 于负半周(即极性反转中的负极性反转,数据信号电位小于共同电极 VCOM: 的电位)期间, 当扫描线 Gate—n在时间 t3和 t4之间传送扫描线信号时, 开关元件 TFT— A 和 TFT— B根据扫描信号幵启, 使得数据线 Data ji和 Data _n+〗上的数据信号分别经由开 关元件 TFT— A和 TFT— B传送至存储电容 CST— Main和 CST— Sub, 存储电容 CST— Main和 CST„Siib则根据数据信号充电而存储相应的电位, 致使子像素电极 V— A和 V—B据此具有 相对应的电位。 需要注意的是, 此 Su 区与 Main区具有一定的电压差 ΔΥ。
接着, 当扫描线 Gate— T1+1在时间 ΐ4和 t5之间传送扫描信号时, 由于关闭了 Share区 的扫描信号, 因此该区的电极 V C的电位与共同电极 VCOM的相同, 视为 0。
如此一来, 无论在正极性反转或负极性反转的操作, Mam区和 Sub区之间有显著的 电位差异,使得这两个区所显示的影像彼此间能够有较为显著的区别, 因此能够有效地解 决在 3D显示时显示器具有色偏的问题。
由上可知, 在 3D显示时, 由于使用 1G2D方式, 即子像素的显示区域只有 Main区 和 Sub区, 其只有一条扫描线 Gate—n控制, 而分别有 Data n和 Dataj +1这两条数据线 来提供不同的数据信号, 因此, 可以任意调整 Main区和 Sub区的电位差, 而实现较佳的
综上所述, 通过采 ffl 1G2D和 3区 (Mam区、 Sub区和 Share区) 12畴的像素结构, 使得在 2D显示的时候, 通过利用 Share区拉低 Sub区的电位实现低色偏作用。 而在 3D 显示的 ^候,通过利 ^插黑的方式将 Share区形成黑色区域,然后关闭该区域的扫描信号, 使其保持暗态, 形成 3D FPR显示所需的较宽间距, 在利用 Main区和 Sub区的数据信号 来实现 3D的低色偏效果。这样, 在保证 2D显示穿透率的条件下, 实现了 2D和 3D兼容 显示, 且使得 2D和 3D都具有低色偏效果, 提高了显示效果。 以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保沪范圈并不局限于此, 任 何熟悉该技术的人员在本发明所揭露的技术范围内,可轻易想到的变化或替换,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该以权利要求的保护范围为准。
