Description

显示装置及其驱动方法 技术领域
本申请涉及一种显示技术领域，特别涉及一种显示装置及其驱动方法。
背景技术
TFT-LCD(主动开关-液晶显示器)中的液晶分子(Liquid Crystal cells)的特性不能够一直固定在某一个电压不变，不然时间久了，即使将电压取消掉，液晶分子会因为特性的破坏而无法再因应电场的变化来转动以形成不同的灰阶。据此，每隔一段时间就必须将电压恢复原状，以避免液晶分子的特性遭到破坏。
因此，已开发有不同类型的极性反转驱动方法。举例而言，有帧反转方法(Frame Inversion Method)，这种方法每隔一个图框，就将提供至液晶分子的显示数据的极性反转。列反转方法(Column Inversion Method)，则是每隔既定的像素列数，就将显示数据的极性反转。类似地，行反转方法(Row Inversion Method)，则是每隔既定的像素行数，就将显示数据的极性反转。点反转方法(dot Inversion Method)则是反转每隔既定像素的数目，就将显示数据的极性反转。
然而，每一种极性反转方法拥有超越其它种反转方法的优点，也有无法避免的缺点存在。举例而言，列反转方法于消除数据线的数据延迟与降低功率消耗上表现出色，但却可能引发垂直闪烁(vertical flickering)现象而降低了影像品质。图框反转方式即便最省功率消耗，但影像品质却最为低劣。点反转方法在对抗闪烁上表现最佳，但功率消耗却最高。而现阶段的显示面板的所有显示区域都是同样的极性控制方式，无法在画面品质、闪烁现象与运行功耗之间取得较好的平衡。
发明内容
为了解决上述技术问题，本申请的目的在于，提供一种显示装置及其驱动方法，通过不同的显示区域施行不同的像素极性反转的方式，改善显示画面闪烁与运作功耗。

本申请的又一目的为一种显示装置，其包括：控制模块；时序模块，设置于所述控制模块，用以指示第一极性反转信号与第二极性反转信号；显示面板，其包括：第一基板，包括显示区与其周边的布线区，所述显示区设置有多条源极线与多条栅极线，多个像素单元设置于多条源极线与多条栅极线的交集处；第二基板，与所述第一基板相对设置；液晶层，设置于所述第一基板与第二基板 之间，所述液晶层包括多个液晶与所述像素单元对应设置；多个源极驱动单元，连接所述多条源极线，所述多个源极驱动单元依据所述第一极性反转信号与所述第二极性反转信号，控制所述多个像素单元对应的所述多个液晶的极性转换；其中，所述多个源极驱动单元对应所述显示区的第一显示区域与第二显示区域，所述第一显示区域位于所述显示区的两侧部位，所述第二显示区域位于所述显示区的中间部位，所述第一极性反转信号与所述第二极性反转信号指示不同类型的极性分布型态，使所述第一显示区域与所述第二显示区域对应的所述多个液晶，依据相对的所述第一极性反转信号与所述第二极性反转信号指示而极性反转。
本申请可以不大幅改变现有生产流程的前提，维持原制程需求和产品成本，就不同的显示区域施行不同的像素极性反转，以在改善显示面板闪烁问题的同时达到降低功耗的效果。因不需调整生产流程，故没有特别的制程要求与难度，故不会提升成本，极具备市场竞争性。而且，不用增加阵列走线面积，适用于现今多种的显示面板设计，当然也适用于面板窄边框设计，符合市场及技术趋势。

具体实施方式
以下各实施例的说明是参考附加的图式，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。
附图和说明被认为在本质上是示出性的，而不是限制性的。在图中，结构相似的单元是以相同标号表示。另外，为了理解和便于描述，附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度。将理解的是，当例如层、膜、区域或基底的组件被称作“在” 另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定申请目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种显示装置及其驱动方法，其具体实施方式、结构、特征及其功效，详细说明如后。
本申请的显示面板可包括第一基板及第二基板，第一基板及第二基板可例如为主动阵列开关(Thin Film Transistor，TFT)基板、彩色滤光层(Color Filter，CF)基板。然不限于此，在一些实施例中，本申请的主动阵列开关及彩色滤光层亦可形成于同一基板上。
在一些实施例中，本申请的所述显示面板可例如为液晶显示面板，然不限于此，其亦可为OLED显示面板，W-OLED显示面板，QLED显示面板，等离子体显示面板，曲面型显示面板或其他类型显示面板。
图1a为范例性的显示装置的架构示意图。请参照图1a，一种显示装置200，包括：控制模块100，所述控制板100包括时序模块(Timing Controller，TCON)101；印刷电路板103，与所述控制模块100之间通过柔性扁平电缆(Flexible Flat Cable，FFC)102相连接；源极驱动单元104与栅极驱动单元105分别与显示区106内的数据线104a及栅极线105a连接，在一些实施例中，栅极驱动单元105及源极驱动单元104包括但不限制为覆晶薄膜形式。
图1b为范例性的像素单元配置示意图。Dn即源极线104a，Gn即栅极线105a，像素单元P设置于多条源极线104a与多条栅极线105a的交集处。
图1c为范例性的极性列反转示意图。图1d为范例性的极性行反转示意图。图1e为范例性的极性点反转示意图。请配合图1a以利于理解。栅极驱动单元105是逐行提供扫描信号给栅极线105a，每一扫描周期提供扫描信号给一行栅极线105a。例如：周期T1提供扫描信号栅极线G1；周期T2提供扫描信号栅极线G2；周期T3提供扫描信号栅极线G3；周期T4提供扫描信号栅极线G4。显示面板的数据线会被逐行打开，源极驱动单元通过数据线提供数据至像素单元P。
如图1c绘示，列反转方法(Column Inversion Method)，则是每隔既定的像素列数，就将显示数据的极性反转。如图1d绘示，行反转方法(Row Inversion Method)，则是每隔既定的像素行数，就将显示数据的极性反转。如图1e绘示，点反转方法(dot Inversion Method)则是反转每隔既定像素的数目，就将显示数据的极性反转。然而，现阶段的显示面板的所有显示区域都是同样的极性控制方式，无法在画面品质、闪烁现象与运行功耗之间取得较好的平衡。
图2a为显示依据本申请的方法，一实施例应用于显示面板的架构示意图。现有技术及结构请同时配合图1a至图1c以利于理解。请参阅图2a，在本申请一实施例中，所述一种显示装置200，包括：第一基板310，包括显示区106与其周边的布线区109，所述显示区106设置有多条源极线104a与多条栅极线105a，多个像素单元P设置于多条源极线104a与多条栅极线105a的交集处；第二基板(图未示)，与所述第一基板310相对设置；液晶层(图未示)，设置于所述第一基板310与第二基板之间，所述液晶层包括多个液晶与所述像素单元P对应设置；时序模块101，用以指示多个极性反转信号(Polarity inversion signal，POL)；多个源极驱动单元104，连接所述多条源极线104a，所述多个源极驱动单元(S1～S12，等同图1a的组件104)依据所述多个极性反转信号，控制所述多个像素单元P对应的所述多个液晶的极性转换；其中，所述多个源极驱动单元104对应所述显示区106的多个显示区域，所述多个极性反转信号(POL)指示不同类型的极性分布型态，使所述多个显示区域对应的所述多个液晶依据相对的极性反转信号指示而极性反转。
图2b为显示依据本申请的方法，一实施例应用于显示面板的极性切换指示示意图。请同时参阅图2a以利于理解。在一些实施例中，所述多个源极驱动单元区分为多个组别，所述多个组别包括但为以此为限的分为第一组321、第二组322与第三组323，以12个源极驱动单元为例，第一组321包括源极驱动单元S1至源极驱动单元S4，第二组322包括源极驱动单元S5至源极驱动单元S8，第三组323包括源极驱动单元S9至源极驱动单元S12。在本申请的一实施例中，所述多个显示区域包括所述显示区106的多个垂直分布区域，其中，第一显示区域331位于所述显示区106的两侧部位，第二显示区域332位于所述显示区的中间部位。所述第二组322对应所述第二显示区域332，所述第一组321及第三组323对应所述第一显示区域331。在一些实施例中，所述第一极性反转信号POL1指示列反转极性分布型态，所述第二极性反转信号POL2指示点反转极性分布型态，故所述第一显示区域331所对应的液晶呈现列反转极性切换，所述第二显示区域332所对应的液晶呈现点反转极性切换。
在一些实施例中，相异显示区域的所述极性分布型态是选择包括列反转、行反转、单点反转、多点反转与帧反转中至少之一。
在一些实施例中，所述多个显示区域对应的极性转换方式为相同、相异或局部相同。
在一些实施例中，所述多个显示区域包括所述显示区的多个横向分布区域。
在一些实施例中，所述多个显示区域的范围大小为相同、相异或局部相同。
在一些实施例中，所述多个极性反转信号中，每一极性反转信号对应一个以上的源极驱动单元。
在一些实施例中，在两个切换时间内，在前一切换时间与后一切换时间，所述多个极性反转信号指示的极性分布型态为相异。例如，前一切换时间为极性行反转切换模式，后一切换时间调整为 极性列反转切换模式。
图3为显示依据本申请的方法，一实施例应用于显示面板的驱动流程示意图。在本申请一实施例中，本申请的一种显示装置的驱动方法，其包括：
步骤S310，通过时序模块101指示多个极性反转信号，所述多个极性反转信号(POL1，POL2)指示不同类型的极性分布型态；
步骤S320，通过多个源极驱动单元104依据所述多个极性反转信号(POL1，POL2)，控制显示区106的不同显示区域(331，332)的液晶极性转换。其中，所述多个极性反转信号(POL1，POL2)指示不同类型的极性分布型态，使所述多个显示区域对应的液晶依据相对的极性反转信号指示而极性反转。
在本申请一实施例中，一种显示装置200，包括：控制模块100；显示面板，其包括：第一基板310，包括显示区106与其周边的布线区109，所述显示区106设置有多条源极线104a与多条栅极线105a，多个像素单元P设置于多条源极线104a与多条栅极线105a的交集处；第二基板(图未示)，与所述第一基板310相对设置；液晶层(图未示)，设置于所述第一基板310与第二基板之间，所述液晶层包括多个液晶与所述像素单元P对应设置；时序模块，用以指示第一极性反转信号POL1与第二极性反转信号POL2；多个源极驱动单元(S1～S12)(等同图1a中所指104)，连接所述多条源极线104a，所述多个源极驱动单元104依据所述第一极性反转信号POL1与所述第二极性反转信号POL2，控制所述多个像素单元P对应的所述多个液晶的极性转换；其中，所述多个源极驱动单元(S1～S12)对应所述显示区106的第一显示区域331与第二显示区域332，所述第一显示区域331位于所述显示区106的两侧部位，所述第二显示区域332位于所述显示区106的中间部位，所述第一极性反转信号POL1与所述第二极性反转信号POL2指示不同类型的极性分布型态，使所述第一显示区域331与所述第二显示区域332对应的所述多个液晶，依据相对的所述第一极性反转信号POL1与所述第二极性反转信号POL2指示而极性反转。
本申请可以不大幅改变现有生产流程的前提，维持原制程需求和产品成本，就不同的显示区域施行不同的像素极性反转，以在改善显示面板闪烁问题的同时达到降低功耗的效果。因不需调整生产流程，故没有特别的制程要求与难度，故不会提升成本，极具备市场竞争性。而且，不用增加阵列走线面积，适用于现今多种的显示面板设计，当然也适用于面板窄边框设计，符合市场及技术趋势。
“在一些实施例中”及“在各种实施例中”等用语被重复地使用。此用语通常不是指相同的实施例；但它也可以是指相同的实施例。“包含”、“具有”及“包括”等用词是同义词，除非其前后文意显示出其它意思。
以上所述，仅是本申请具体的实施例而已，并非对本申请作任何形式上的限制，虽然本申请已以具体的实施例揭露如上，然而并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
