显示面板的驱动方法及显示装置
相关申请的交叉引用
本申请要求于2017年12月18日提交中国专利局、申请号为2017113690314、申请名称为“显示面板的驱动方法及显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，特别是涉及一种显示面板的驱动方法及显示装置。
背景技术
大尺寸液晶显示面板大多采用负型垂直配向(Vertical Alignment，VA)式或者共平面切换(In Panel Switching，IPS)式。VA型液晶技术相较于IPS液晶技术存在较高的生产效率及低制造成本的优势，但相较于IPS液晶技术，则存在较明显的光学性质缺陷，例如在大视角图像呈现时，VA型液晶显示面板会存在色偏。
在进行图像显示时，像素的亮度在理想情况下应该是随着电压的变化呈现线性的变化，这样像素的驱动电压就能够准确表示像素的灰阶，并通过亮度体现出来。采用VA型液晶技术以较小的视角观看显示面时(例如正视)，像素的亮度可以符合理想情况，即随电压呈现线性变化；但当以较大的视角观看显示面时(例如与显示面呈160度以上)，由于VA型液晶技术原理所限，像素的亮度随着电压呈现出快速饱和，然后缓慢变化的情况。这样一来，大视角下，驱动电压原本应该呈现的灰阶，出现了严重的偏离，即出现色偏。
用于改善色偏的方式是将每一个子像素都再细分为一个主像素和次像素，然后用相对高的驱动电压驱动主像素，用相对低的驱动电压驱动次像素，主像素和次像素一起显示一个子像素。并且所述相对高的驱动电压和相对低 的驱动电压在驱动主像素和次像素时，能够维持正视视角下的亮度与对应灰阶的关系不变，并且能够改善大视角下的色偏情况。
但上述方法存在的问题是，需要增加一倍的金属走线和驱动器件来驱动次像素，使可透光开口区牺牲，影响面板透光率，同时成本也更高。

具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于发明的技术领域的技术人员通常理解的含义相同。本文中在发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
以下以液晶显示面板为例说明各实施例的显示方法。可以理解，在其他与液晶显示类似的显示技术中，也可以采用该方法以解决大视角色偏的问题。
在进行图像显示时，像素的亮度在理想情况下应该是随着电压的变化呈现线性的变化，这样像素的驱动电压就能够准确表示像素的灰阶，并通过亮度体现出来。如图1a所示，采用VA型液晶技术时，以较小的视角观看显示面时(例如正视)，像素的亮度可以符合理想情况，即随电压呈现线性变化，如图1a中的理想曲线所示；但当以较大的视角观看显示面时(例如与显示面呈160度以上)，由于VA型液晶技术原理所限，像素的亮度随着电压呈现出快速饱和，然后缓慢变化的情况，如图1a中的实际曲线所示。这样一来，大视角下，驱动电压原本应该呈现的灰阶，出现了严重的偏离，即出现色偏。
传统用于改善色偏的方式是将每一个子像素都再细分为一个主像素和次像素，然后用相对高的驱动电压驱动主像素，用相对低的驱动电压驱动次像 素，主像素和次像素一起显示一个子像素。并且所述相对高的驱动电压和相对低的驱动电压在驱动主像素和次像素时，能够维持正视视角下的亮度与对应灰阶的关系不变。一般地，是采用如图1b所示的方式，灰阶的前半段，主像素用相对高的驱动电压驱动显示、次像素不显示，整个子像素的亮度就是主像素亮度的一半；在灰阶的后半段，主像素用相对高的驱动电压驱动显示、次像素用相对低的驱动电压驱动显示，整个子像素的亮度就是主像素的亮度加上次像素的亮度的和的一半。这样合成后，大视角下的亮度曲线如图1b中的实际曲线，其更接近理想曲线，因此大视角下的色偏情况有所改善。
图2为液晶驱动结构示意图。在该液晶驱动结构中，多个子像素结构呈阵列排布，在每一行会输入扫描信号Si(1≤i≤m)，在每一列会输入数据信号Dj(1≤j≤n)。一般地，扫描信号Si逐行输入，即S1到Sm以固定的周期依序输入高电平，使该行的子像素输入数据信号。当扫描信号输入完成后，完成一帧图形的显示。通常地，一帧扫描时间为1/60秒，即刷新频率为60赫兹。
图3为子像素结构示意图。该子像素结构包括一个三端开关器件T1，一般为薄膜晶体管，在其栅极输入扫描信号Si，在其源极输入数据信号Dj，并在漏极连接两个并联的电容Cs、Clc，其中电容Cs为储能电容，电容Clc为液晶电容。并联电容的另一端可以连接公共电压Vcom。
当扫描信号Si输入高电平时，薄膜晶体管T1开通，接收输入数据信号Dj(电压信号)。数据信号Dj与公共电压Vcom之间的电压差使电容Cs、Clc充电，其中Clc之间的电压使处于其中的液晶分子发生偏转，使背光根据液晶分子的偏转程度透射出相应程度的光，从而使该子像素呈现相应的亮度。电容Cs用于保持该电压直到下次扫描来临。
数据信号Dj的电压可以高于公共电压Vcom，也可以低于公共电压Vcom。当二者的电压差的绝对值相同，而符号相反时，驱动子像素显示的亮度相同。当数据信号Dj的电压高于公共电压Vcom时，在以下实施例中，称为正极性驱动，否则称为负极性驱动。
对每一个子像素结构，其用于驱动显示一个子像素。例如，对于三色像素单元，其中的子像素为红色子像素(R)、绿色子像素(G)以及蓝色子像素(B)；对于四色像素单元，其中的子像素为红色子像素(R)、绿色子像素(G)、蓝色子像素(B)以及白色子像素(W)。
以下实施例提供一种显示阵列的驱动方法。在以下实施例中，子像素结构用简化的方框表示，必要时在方框中标注其驱动显示的子像素类型。该驱动方法用于驱动如图4所示的显示阵列100。
在一个实施例中，显示阵列100包括呈阵列排布的像素单元(包括第一像素单元112、第二像素单元114)。其中第1、3、5......等奇数行由第一像素单元112排列形成，第2、4、6......等偶数行与由第二像素单元114排列形成。
在一个实施例中，参考图5a，所述第一像素单元112包括行方向上依次排列的第一子像素P1、第二子像素P2、第三子像素P3以及第四子像素P4。参考图5b，所述第二像素单元114包括行方向上依次排列的第三子像素P3、第四子像素P4、第一子像素P1以及第二子像素P2。在该显示阵列100中，对处于同一列的第一像素单元112和第二像素单元114，所述第一像素单元112的四个子像素和第二像素单元114的四个子像素根据排列的顺序分别在列上对齐。
可以理解，在其他实施例中，奇数行也可以是由第二像素单元114形成，同时偶数行由第一像素单元112形成。在上述实施例中，第一子像素、第二子像素、第三子像素以及第四子像素可以分别对应于红色子像素、绿色子像素、蓝色子像素以及白色子像素，但并不限于此，也可以是不同的其他排列对应关系，或者采用其他可行的子像素方案。
如图6所示，所述驱动方法包括以下步骤S110～S120。
步骤S110：对任意两个相邻的像素单元，分别采用相对高电压的驱动数据和相对低电压的驱动数据进行驱动。参考图7，在行上，两个相邻的第一像素单元112分别采用相对高电压的驱动数据VH和相对低电压的驱动数据VL进行驱动；在列上，第一像素单元112和第二像素单元114分别采用相对 高电压的驱动数据VH和相对低电压的驱动数据VL进行驱动。即对整个液晶显示阵列来说，任意相邻的两个像素单元所对应的驱动数据都是相对高电压和相对低电压的。
其中，相对高电压的驱动数据是指，对于所驱动的像素单元，输入的针对子像素的驱动信号要普遍高于设定的阈值；相对低电压的驱动数据是指，对于所驱动的像素单元，输入的针对子像素的驱动信号要普遍低于设定的阈值。该阈值可以是正常驱动一个子像素时所对应的值。
需要说明的是，对应于不同的灰阶，该阈值是不同的。例如，在正常驱动一个子像素时，若要显示0～255的灰阶，则对应需要输入V 0～V 255的驱动电压(即驱动子像素显示0～255的灰阶所需输入的额定电压分别为V 0～V 255)。若将该阈值设为正常驱动一个子像素时的电压V k(0≤k≤255，k为整数)，则在使用相对高电压的驱动数据驱动像素单元显示时，在本实施例中，该驱动数据包括驱动第一子像素、第二子像素、第三子像素以及第四子像素的4个电压值V P1、V P2、V P3、V P4，且每个电压应该都高于对应的子像素在正常驱动时的电压。例如该像素单元对应的驱动数据为(128，255，160，0)，即第一子像素的灰阶为128，第二子像素的灰阶为255，第三子像素的灰阶为160，第四子像素的灰阶为0。则V P1＞V 128，V P2＞V 255，V P3＞V 160，V P4＞V 0。类似地，相对低电压的驱动数据就是驱动电压普遍低于正常驱动一个子像素时所对应的电压。
采用上述驱动方法，可以将相邻像素单元的亮度互相平均，获得正常的亮度显示。同时，在大视角观看时，可以获得和采用主像素/次像素方案同样的效果，从而起到改善色偏的作用。同时，每个子像素都是正常子像素的大小，不需要额外的金属布线以及驱动元件，成本不会升高。
在一个实施例中，对每一像素单元，采用相对高电压的驱动数据进行驱动，包括：输入像素单元的各子像素的驱动信号高于为各子像素对应设定的阈值，并在第一设定范围内取值。采用相对低电压的驱动数据进行驱动，包括：输入像素单元的各子像素的驱动信号低于为各子像素对应设定的阈值， 并在第二设定范围内取值。
其中，在第一设定范围内取值时需保证电压不至于高过各子像素单元正常工作所能承受的最高电压，以避免电压过高而损坏子像素单元。在第二设定范围内取值时需保证电压不至于低于子像素单元正常工作所需的最低电压。并且高电压的驱动数据的取值和低电压的驱动数据的取值使得整体的显示效果符合预期。
在一个实施例中，步骤S120：以三列像素单元为周期，对其中第一列像素单元采用第一极性排列驱动，对剩余两列相邻像素单元采用第二极性排列驱动；或者对其中第一列像素单元和第二列像素单元采用第一极性排列驱动，对剩余一列相邻像素单元采用第二极性排列驱动。其中，所述第一极性排列驱动为：对像素单元中的四个子像素分别进行正极性驱动、负极性驱动、负极性驱动以及正极性驱动；所述第二极性排列驱动为：对像素单元中的四个子像素分别进行负极性驱动、正极性驱动、正极性驱动以及负极性驱动。
采用步骤S110的驱动显示方式时，会有多种不同的子像素极性驱动方案。例如帧反转(frame inversion)、行反转(row inversion)、列反转(column inversion)以及点反转(dot inversion)。其目的是为了避免液晶分子在转动过程中长期使用一个方向的电压导致的各种问题。其中，帧反转是指，在任意两帧图像切换前后，每个像素点的驱动电压的极性(即驱动信号的电压Dj相对于公共电压Vcom的大小)都会发生变化。行反转是指，任意两行像素点在同一帧下的驱动电压的极性都不相同。列反转是指，任意两列像素点在同一帧下的驱动电压的极性都不相同。点反转是指，任意两个像素点在同一帧下的驱动电压的极性都不相同。行反转、列反转以及点反转同时也包含帧反转。
点反转驱动最能解决上述问题，因此一般都采用点反转驱动。但对于采用上述步骤S110的驱动方式的液晶显示方案来说，点反转驱动存在问题。
举例若同一行由多个相对高电压子像素驱动，多个低电压子像素驱动不显示(即灰阶为0)，此时同一行正极性电压和负极性电压就会失衡。由于液 晶显示器金属走线存在寄生电容的影响，高电压正负极性的不匹配会使得Vcom位准电压受到寄生电容的影响，当高电压负极性数量多于高电压正极性子像素驱动时，会使得Vcom位准等效电压倾向负极性，即相较于原Vcom位准降低为Vcom-ΔV，这样的结果会使得代表高电压正极性子像素实际充电电荷增加、亮度变亮，相反地使得代表高电压负极性子像素实际充电电荷减少、亮度变暗。
因此，在本实施例中，以三列像素单元为周期，对其中第一列像素单元采用第一极性排列驱动，对剩余两列相邻像素单元采用第二极性排列驱动。如图8所示，对第1列，采用第一极性排列驱动，对第2～3列，采用第二极性排列驱动。之后以三列像素周期性重复，即4列采用第一极性排列驱动、5～6列采用第二极性排列驱动......
以下以所述第一子像素、第二子像素、第三子像素以及第四子像素分别对应为红色子像素(R)、绿色子像素(G)、蓝色子像素(B)以及白色子像素(W)为例进行说明。第一极性排列驱动为：对像素单元中的四个子像素分别进行正极性驱动(+)、负极性驱动(-)、负极性驱动(-)以及正极性驱动(+)。第二极性排列驱动为：对像素单元中的四个子像素分别进行负极性驱动(-)、正极性驱动(+)、正极性驱动(+)以及负极性驱动(-)。
如图8所示：
在第1列第1行的像素单元中，红色子像素为正极性驱动(R+)、绿色子像素为负极性驱动(G-)、蓝色子像素为负极性驱动(B-)、白色子像素为正极性驱动(W+)。
在第1列第2行的像素单元中，蓝色子像素为正极性驱动(B+)、白色子像素为负极性驱动(W-)、红色子像素为负极性驱动(R-)、绿色子像素为正极性驱动(G+)。
在第1列后续行的像素单元中，以第1行和第2行的方式重复。
在第2列第1行的像素单元中，红色子像素为负极性驱动(R-)、绿色子像素为正极性驱动(G+)、蓝色子像素为正极性驱动(B+)、白色子像素为负 极性驱动(W-)。
在第2列第2行的像素单元中，蓝色子像素为负极性驱动(B-)、白色子像素为正极性驱动(W+)、红色子像素为正极性驱动(R+)、绿色子像素为负极性驱动(R-)。
在第2列后续行的像素单元中，以第1行和第2行的方式重复。
在第3列第1行的像素单元中，红色子像素为负极性驱动(R-)、绿色子像素为正极性驱动(G+)、蓝色子像素为正极性驱动(B+)、白色子像素为负极性驱动(W-)。
在第3列第2行的像素单元中，蓝色子像素为负极性驱动(B-)、白色子像素为正极性驱动(W+)、红色子像素为正极性驱动(R+)、绿色子像素为负极性驱动(R-)。
在第3列后续行的像素单元中，以第1行和第2行的方式重复。
之后以3列像素为周期重复。
对其中第一列像素单元和第二列像素单元采用第一极性排列驱动，对剩余一列相邻像素单元采用第二极性排列驱动时，可参照上述方式。
这样，在步骤S110的基础上，增加步骤S120的极性排列驱动，四个子像素(RGBW)同时具备相同数目的高电压正极性驱动像素及负极性驱动像素，可以确保不管任何的颜色组合，具备高电压正、负极性的子像素数量匹配而且同颜色像素(R、G、B、W)同时具备相同的高电压正、负极性的子像素数目，这样的驱动会使得Vcom位准不受到影响，同一行的子像素相对Vcom位准不受到影响即能确保图像信号正确性，不会发生色偏偏色或画质异常的现象。确保该空间上使用高电压像素单元及低电压像素单元解决视角色偏问题可以得到实现。
在其中一个实施例中，在行方向上，每两个像素单元形成为一个像素组并将显示一个像素单元的驱动数据转换为所述相对高电压驱动数据和相对低电压驱动数据驱动所述像素组。
在其中一个实施例中，每两个相邻的第一像素单元和第二像素单元形成 为一个像素组，并将显示一个像素单元的驱动数据转换为所述相对高电压驱动数据和相对低电压驱动数据驱动所述像素组。
基于相同发明构思，以下提供一种显示装置。如图9所示，该显示装置包括图4所示的显示阵列100和驱动模块200。对显示阵列100可以参考上述实施例中的说明，在此不赘述。该显示装置可以为液晶显示装置，该显示阵列100对应为液晶显示阵列。
驱动模块200用于输出驱动数据使显示阵列显示图像。驱动模块200用于：
(1)对任意两个相邻的像素单元，分别采用相对高电压的驱动数据和相对低电压的驱动数据进行驱动；
(2)以三列像素单元为周期，对其中第一列像素单元采用第一极性排列驱动，对剩余两列相邻像素单元采用第二极性排列驱动；或者对其中第一列像素单元和第二列像素单元采用第一极性排列驱动，对剩余一列相邻像素单元采用第二极性排列驱动。
其中，所述第一极性排列驱动为：对像素单元中的四个子像素分别进行正极性驱动、负极性驱动、负极性驱动以及正极性驱动；
所述第二极性排列驱动为：对像素单元中的四个子像素分别进行负极性驱动、正极性驱动、正极性驱动以及负极性驱动。
驱动模块200可以包括扫描单元210和驱动单元220，扫描单元210用于输出扫描信号，一般是逐行对像素单元进行扫描，驱动单元220则输出驱动信号，使像素单元在被扫描到时接收驱动数据进行显示。
驱动模块200对第(1)部分的处理可以参考上述实施例的步骤S110。经过该处理，可以将相邻像素单元的亮度互相平均，获得正常的亮度显示。同时，在大视角观看时，可以获得和采用主像素/次像素方案同样的效果，从而起到改善色偏的作用。同时，每个子像素都是正常子像素的大小，不需要额外的金属布线以及驱动元件，成本不会升高。
驱动模块200对第(2)部分的处理可以参考上述实施例的步骤S120。 在步骤S110的基础上，增加步骤S120的极性驱动排列，四个子像素(RGBW)同时具备相同数目的高电压正极性驱动像素及负极性驱动像素，可以确保不管任何的颜色组合，具备高电压正、负极性的子像素数量匹配而且同颜色像素(R、G、B、W)同时具备相同的高电压正、负极性的子像素数目，这样的驱动会使得Vcom位准不受到影响，同一行的子像素相对Vcom位准不受到影响即能确保图像信号正确性，不会发生色偏偏色或画质异常的现象。确保该空间上使用高电压像素单元及低电压像素单元解决视角色偏问题可以得到实现。
在其中一个实施例中，在行方向上，每两个像素单元形成为一个像素组；所述驱动模块输出用于显示一个像素单元的驱动数据并转换为所述相对高电压驱动数据和相对低电压驱动数据驱动所述像素组。
在其中一个实施例中，每两个相邻的第一像素单元和第二像素单元形成为一个像素组；所述驱动模块输出用于显示一个像素单元的驱动数据并转换为所述相对高电压驱动数据和相对低电压驱动数据驱动所述像素组。
需要说明的是，显示装置例如为LCD(Liquid Crystal Display)显示装置、OLED(Organic Light-Emitting Diode)显示装置、QLED(Quantum Dot Light Emitting Diodes)显示装置、曲面显示装置或其他显示装置。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
