Description

驱动装置及显示面板 技术领域
本申请涉及一种显示技术领域，特别涉及一种驱动装置及其驱动方法和显示面板。
背景技术
TFT-LCD(主动开关-液晶显示器)面板正常显示时，需要栅级驱动线路(Gate Driver)结合栅极线(Gate line)、源极驱动线路(Source)结合数据线(Data line)、给彩色滤光片基板的共同电极(彩膜共同电极，CF com)和存储电极。其中像素(pixel)电极信号由数据线通过主动开关(TFT)打开后供给。存储电极信号由有效显示区外围的阵列共享线(AA Com)供给，以与像素电极之间形成存储电容(Cst)。彩膜共同电极信号由阵列基板的阵列外布线(Wire On Array，WOA)的共同电压线路供给彩色滤光片基板，彩膜共同电极与像素电极之间形成液晶电容(Clc)。
其中，显示面板是以逐行(Line By Line)的方式把每一条数据线打开。具体实现方式为，栅级驱动线路接受行信号，每经过一个扫描信号的上升沿就产生出一个数字信号。而每一个数字信号对应一个输出。通过数模转换，将高低电平转换为像素单元充电需要的电压数值，使显示面板的数据线被逐行打开，再通过像素电极对存储电容及液晶电容进行充电。
液晶分子的转动需要几毫秒的时间，但一条扫描线开启的时间，液晶分子时常无法来得及响应即进入了电荷保持时间，造成液晶分子转动不足，从而无法达到希望的电压值和电容值，造成较不好的液晶动态电容效应，因此时常需要给像素单元更高的电压才能达到液晶分子需求的电容值与电压值。
发明内容
为了解决上述技术问题，本申请的目的在于，提供一种驱动装置及显示面板，通过提供扫描信号给栅极线组的方式，改善液晶动态电容效应。

本申请解决其技术问题还可采用以下技术措施进一步实现。
在本申请的一实施例中，所述驱动装置还包括：使能驱动单元，在每一个扫描周期内，提供使能信号给所述栅极驱动单元，管控所述栅极驱动单元轮替提供所述栅极驱动信号的时间。

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驱动装置及其驱动方法和显示装置，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：控制板100，所述控制板101包括时序模块(Timing Controller，TCON)101；印刷电路板103，与所述控制板 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为范例性的扫描信号示意图，图1c为范例性的像素单元配置示意图。请配合图1a以利于了解。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，液晶电容Clc是随不同的电压而改变的。例如，一个液晶电容Clc上的电压为0V，液晶电容为2.4pF，通过施加一个工作电压后，希望在液晶电容Clc两端得到一个电压为5V，液晶电容为6.9pF。然而，由于液晶分子的转动需要几毫秒的时间，每一条扫描线105a开启的时间(约16us)内，液晶分子不一定来不及响应。假设液晶分子来不及响应，液晶电容Clc基本是维持在2.4pF。接着，像素单元P会进入电荷保持时间，液晶分子缓慢转动，液晶电容Clc会相对的逐渐增加，而液晶电容Clc两端的电压会降低，最后稳定到2.2V，液晶电容Clc则为5.5pF。如此即无法达到预期的电压和电容，导致液晶动态电容效应产生。此种情形在数据线104a采用逐行(Line By Line)打开的情形较为明显，因此需要提供更高的工作电压才能达到需求的液晶电容电压。
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驱动装置的架构示意图。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，所述一种驱动装置300，包括：多个栅极线组310，每一栅极线组310包括多条栅极线105a；栅极驱动单元105，连接多个栅极线组310，在每一个扫描周期输入栅极驱动信号；其中，在一扫描周期中，所述栅极驱动单元105轮替提供扫描信号给所述多条栅极线105a。
在一些实施例中，所述扫描周期划分为多个子周期，所述栅极驱动单元105在相异的所述多个子周期提供扫描信号给相异的栅极线105a。
在一些实施例中，所述多个子周期的周期数量为所述多条栅极线105a的线条数量的倍数。在一些实施例中，所述倍数为至少为二的正整数。
在一些实施例中，所述多个子周期的时间长度为相同、相异或局部相同。
在一些实施例中，所述栅极线组310包括二条栅极线、三条栅极线或四条栅极线。
图2b为显示依据本申请的方法，一实施例应用于驱动装置的驱动波形示意图，请配合图2a以利于理解。如图2a所示，在一些实施例中所述栅极线组310包括二条栅极线。第一扫描周期T1被等分为所述多条栅极线的线条数量的二倍，即时间长度相等的四个子周期。如图2b所示，在第 一子周期T11内，所述栅极驱动单元105提供所述扫描信号给所述第一栅极线G1。在第二子周期T12内，所述栅极驱动单元105提供所述扫描信号给所述第二栅极线G2。在第三子周期T13内，所述栅极驱动单元105提供所述扫描信号给所述第一栅极线G1。在第四子周期T14内，所述栅极驱动单元105提供所述扫描信号给所述第二栅极线G2。如此，在一个扫描周期，即四个子周期内，所述栅极驱动单元105以轮替方式，将所述扫描信号提供给所述第一栅极线G1与所述第二栅极线G2。同理，第一扫描周期T1被等分为时间长度相等的四个子周期。如图2b所示，在第一子周期T21内，所述栅极驱动单元105提供所述扫描信号给所述第一栅极线G3。在第二子周期T22内，所述栅极驱动单元105提供所述扫描信号给所述第二栅极线G4。在第三子周期T23内，所述栅极驱动单元105提供所述扫描信号给所述第一栅极线G3。在第四子周期T24内，所述栅极驱动单元105提供所述扫描信号给所述第二栅极线G4。如此，在一个扫描周期，即四个子周期内，所述栅极驱动单元以轮替方式，将所述扫描信号提供给所述第三栅极线G3与所述第四栅极线G4。
图2c为显示依据本申请的方法，一实施例应用于驱动装置的驱动波形示意图。在一实施例中，所述扫描周期对应多个轮替回合，所述栅极线组310中，每一栅极线105a皆已进行一次传输扫描信号时，视为一轮替回合，前一轮替回合对应的子周期时间比次一轮替回合对应的子周期时间长。如图2c所绘示，所述扫描周期画对应到两个轮替回合，所述扫描周期画被划分为所述多条栅极线的线条数量的二倍，即四个子周期，每一轮替回合对应两个子周期。其中，第一轮替回合对应的子周期(T11，T12)的时间比第二轮替回合对应的子周期(T13,T14)时间长。
在一些实施例中，所述扫描周期对应多个轮替回合，前一轮替回合对应的子周期时间比次一轮替回合对应的子周期时间短。
图2d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装置的架构示意图。如图2d绘示，所述驱动装置300还包括使能驱动单元330，在每一个扫描周期内，提供使能信号OE给所述栅极驱动单元105，管控所述栅极驱动单元105轮替提供所述栅极驱动信号的时间。
在一些实施例中，所述驱动装置300还包括控制线路321，用以传输控制信号；所述栅极驱动单元105在所述控制信号处于高电位时，延长所述扫描周期的时长，并轮替提供扫描信号给所述多条栅极线105a。在一些实施例中，所述栅极驱动单元105在所述控制信号处于低电位时，每一扫描周期对相对应的行数的栅极线105a提供所述扫描信号。
图3为显示依据本申请的方法，一实施例应用于显示装置的架构示意图。如图3绘示，在本申请一实施例中，一种显示装置200，包括：显示基板，包括显示区106及其外围的布线区109，所述显示区106设置多个主动开关、多条栅极线105a及多条源极线104a，每一栅极线105a与每一源极线104a交集处设置有像素单元P；源极驱动单元104，连接所述多条源极线104a；时序模块 320，连接所述源极驱动单元104及所述栅极驱动单元105；多个栅极线组310，由多条栅极线105a划分而成，每一栅极线组310包括第一栅极线311与第二栅极线312；栅极驱动单元105，连接多个栅极线组310，每一周期提供扫描信号给所述多个栅极线组310中其一组；控制线路321，连接于所述时序模块320与所述栅极驱动单元105之间，用以传输所述时序模块320提供的控制信号；使能驱动单元330，在每一个扫描周期内，提供使能信号OE给所述栅极驱动单元105，管控所述栅极驱动单元105提供所述栅极驱动信号的时间；其中，所述栅极驱动单元105在所述控制信号处于高电位时，延长所述扫描周期的时长，并将每一扫描周期等分四个子周期，所述栅极驱动单元105在奇数所述子周期提供所述扫描信号给所述第一栅极线311，所述栅极驱动单元105在偶数所述子周期提供所述扫描信号给所述第二栅极线312，以轮替提供所述扫描信号给所述第一栅极线311与所述第二栅极线312；所述栅极驱动单元105在所述控制信号处于低电位时，每一扫描周期对相对应的行数的栅极线105a提供所述扫描信号。
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，调整液晶电容的充电时间，减少液晶分子来不及响应的情形，使得显示面板的各像素液晶电容的电压值与电容值尽可能的达到期望值，以改善液晶动态电容效应。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。
