Description

显示面板的驱动方法及显示设备
相关申请:
本申请要求于2019年1月30日提交中国专利局、申请号为201910101643.8,发明名称分别为“显示面板的驱动方法及显示设备”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
本申请涉及显示面板技术领域,特别涉及一种显示面板的驱动方法及显示设备。
背景技术
这里的陈述仅提供与本申请有关的背景信息,而不必然地构成现有技术。
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;但当以较大的视角观看显示面(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。一般地,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。
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。

本申请提出一种显示面板的驱动方法。参照图1,图1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。
参照图2,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。
参照图4,所述显示面板包括显示阵列,所述显示阵列包括呈阵列排布的像素单元10。本实施例中,每一像素单元10包括依次排列的第一子像素、第二子像素及第三子像素,第一子像素、第二子像素及第三子像素分别为红色子像素、绿色子像素及蓝色子像素。由图4中可知,同一行像素驱动电压的电压为VH、VL、VH、VL……。图4中“+”标示正极性像素,“-”标示负极性像素。
参照图3,所述显示面板的驱动方法方法包括:
S100、对任意相邻的两个像素单元10采用第一驱动数据和第二驱动数据进行驱动。本实施例中,第一驱动数据为相对高电压的驱动数据,第二驱动数据为相对低电压的驱动数据。其中,相对高电压的驱动数据是指,对于所驱动的像素单元10,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10,输入的针对子像素的驱动信号要普遍低于设定的阈值。
S200、对同一列子像素中预设子像素采用第一共极性电压进行驱动,对同一列子像素中其余子像素采用第二共极性电压驱动,第一共极性电压与第二共极性电压的极性相反。
本实施例中,在列方向上,从上往下,预设子像素为奇数位的子像素,例如,1,3,5……2N+1。其余子像素为偶数位的子像素,例如2,4,6……2N+2。对奇数位的子像素采用第一共极性电压进行驱动,对偶数位的子像素采用第二共极性电压驱动。
在接收数据驱动电路输入的数据驱动信号反转时,对所述共极性电压进行周期性反转。其中,所述共极性电压包括第一共极性电压和第二共极性电压。易于理解的是,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。
本申请技术方案中的显示面板包括显示阵列,所述显示阵列包括呈阵列排布的像素单元10,本申请技术方案中通过将所述像素单元中的子像素的共电极采用第一共极性电压和第二共极性电压进行交错驱动,并配合第一驱动数据和第二驱动数据对像素单元进行驱动,从而解决视角色偏,改善了显示面板的显示效果,并通过共电极进行相应的驱动,从而减少驱动芯片的工作,降低驱动芯片的功耗以及温度提升风险,并不需要增加一倍的金属走线和驱动器件来驱动次像素,达到节约成本的目的。
进一步地,在所述数据驱动电路输入的数据驱动信号反转时,对共极性电压进行周期性反转之前,所述显示面板的驱动方法还包括:
分别选取同一列相邻的两个子像素,对选取的子像素中的高电压子像素的等效驱动电压以大于所述选取的子像素中的低电压子像素的等效驱动电压进行驱动。
在具体实现中,当frame1图框时序时,高电压子像素等效驱动电压VGd_1即为正极性驱动电压Vgd=V1(V1>Vcom)与负极性共电极电Vcom1(Vcom1<Vcom)的压差,亦即VGd_1=|V1-Vcom1|,次一相邻低电压子像素VGd_2即为正极性驱动电压Vgd=V1(V1>Vcom)与正极性共电极电Vcom2(Vcom2>Vcom)的压差,亦即VGd_2=|V1-Vcom2|,所以 VGd_1>VGd_2。同理依序高电压VGd_3及低电压子像素VGd_4驱动,高电压子画素等效驱动电压VGd_3即为正极性驱动电压Vgd=V2 (V2>Vcom)与负极性共电极电Vcom1(Vcom1<Vcom)的压差,亦即VGd_3=|V2-Vcom1|,次一相邻低电压子像素VGd_4即为正极性驱动电压Vgd=V2 (V2>Vcom)与正极性共电极电Vcom2(Vcom2>Vcom)的压差,亦即VGd_4=|V2-Vcom2|,所以 VGd_3>VGd_4,从而实现相邻子像素为高低电压交替排列,并搭配对所述显示阵列中的子像素采用帧反转的驱动方式,从而达到减少色偏的目的。
进一步地,所述对同一列子像素中预设子像素采用第一共极性电压进行驱动,对同一列子像素中除所述预设子像素之外的其余子像素采用第二共极性电压驱动,包括:
对同一列子像素中预设子像素的等效驱动电压采用正/负极性驱动的驱动电压与所述预设电压的压差进行驱动;
对同一列子像素中除所述预设子像素之外的其余子像素的等效驱动电压采用正/负极性驱动的驱动电压与所述预设电压的压差的绝对值进行驱动。
本实施例中,以6×9阵列子像素为例进行说明。每一行包括与三组像素单元10。
为配合得的像素电压驱动方式,参照图4及图5,绿色高电压子像素VGd_1  、VGd_3 、VGd_5对应的第一预设电压为Vcom1,绿像素低电压子像素VGd_2  、VGd_4 、VGd_6对应的第二预设电压为Vcom2。随着相邻两帧驱动信号的反转。本实施例中,第一预设电压和第二预设电压是指共电极电压,共电极电压亦配合极性的驱动反转而进行帧周期性电压的切换(附图5, frame 1/frame2 所示帧切换时序)。
高电压子像素等效驱动电压VGd_1即为驱动电压Vgd=V1与共电极电Vcom1的压差,亦即VGd_1=|V1-Vcom1|,相邻低电压子像素VGd_2即为驱动电压V1与共电极电Vcom2的压差,亦即VGd_2=|V1-Vcom2|,其中Vcom1< Vcom2,所以 VGd_1>VGd_2。同理依序高电压VGd_3及低电压子像素VGd_4驱动,高电压子像素等效驱动电压VGd_3即为驱动电压Vgd=V2与共电极电Vcom1的压差,亦即VGd_3=|V2-Vcom1|,相邻低电压子像素VGd_4即为驱动电压Vgd=V2与共电极电Vcom2的压差,亦即VGd_4=|V2-Vcom2|,其中Vcom1< Vcom2,所以 VGd_3>VGd_4。其中,等效驱动电压VGd_1与VGd_2共用驱动电压Vgd=V1,等效驱动电压VGd_3与VGd_4共用驱动电压Vgd=V2,驱动方式采用列反转(column inversion)的信号驱动方式,可以确保同一帧两个子像素共用一驱动信号Vd,相当于原驱动信号的频率减半,可以减少驱动芯片的工作,降低了驱动芯片的功耗及驱动芯片的温度提升风险。
进一步地,同一列相邻子像素采用相同的驱动数据进行驱动。
进一步地,在数据驱动电路输入的数据驱动信号反转时,对共极性电压进行周期性反转之前,所述显示面板的驱动方法包括:
对同一列相邻子像素中的高电压子像素和低电压子像素的等效驱动电压采用预设数据驱动信号进行驱动,所述预设数据驱动信号为原始同一列相邻的两个子像素的驱动信号的平均信号。
需要说明的是,VGd_1与VGd_2共用驱动电压Vgd=V1可以优选为原帧像素信号Gd1与Gd2信号的平均信号,亦即G1=( Gd1+Gd2)/2,G1对应的驱动电压V1。VGd_3与VGd_4共用驱动电压Vgd=V2则可以优选为原帧像素信号Gd3与Gd4信号的平均信号,亦即G2=( Gd3+Gd4)/2,G2对应的驱动电压V2,两个相邻高低电压子像素驱动电压共用以及column inversion的驱动方式,大大的减少了驱动信号频繁的切换,直接驱动频率降低为1/2,可以减少驱动IC的工作,降低了驱动IC的功耗及驱动IC的温度提升风险。
请继续参考附图4,R、G、B三个子像素构成一个单位像素,相邻任一单位像素是以高低电压驱动穿插排列。
G 列子像素有两条共电极电压电路,分别为Vcom1及Vcom2两个共电极电压,G列子像素的高电压子像素与低电压子像素分别对应第一预设电压Vcom1与第二预设电压Vcom2,驱动信号采用列反转的方式进行极性切换,共电极电压也随着帧驱动信号极性的切换进行切换,确保高电压子像素VGd_1对应共电极电压Vcom1的等效电压VGd_1=|V1-Vcom1|高于低电压子像素VGd_2对应共电极电压Vcom2的等效电压VGd_2=|V1-Vcom2|。
参可附图4中B列的R、G、B列相邻的三列子像素驱动排列方式说明,同一行子像素如G列子像素两侧的R、B 列子像素高低电压同G 列子像素高低电压驱动。因此,为了实现高低电压正常穿插驱动,与G列相邻的R、B 列各有的一组共电极电压对应为Vcom2与Vcom1,与G 列同一位置的共电极电压Vcom1与Vcom2相同。以B列子像素为例,与高电压子像素VGd_1相邻的低电压子像素VBd_1对应共电极电压Vcom1的等效电压VBd_1=|VB1-Vcom2|,与低电压子像素VGd_2相邻的高电压子像素VBd_2对应共电极电压Vcom2的等效电压VBd_2=|VB1-Vcom1|,其中Vcom1<Vcom<Vcom2,又由于VB1<Vcom(该说明中G 列为正极性即V1>Vcom,B 列为负极性即VB1<Vcom),所以等效电压确保VBd_1<VBd_2。R列子像素同于B列子像素。
B列中的R、G、B 列子像素对应的各共电极电压分别为R子像素Vcom1、Vcom2,G子像素Vcom1、Vcom2 ,B子像素Vcom1、Vcom2。A列、C列与B列得R、G、B 列极性驱动方式相同,A列、C列中的R、G、B 列子像素对应的各共电极电压驱动信号与B列中的R、G、B 列子像素对应的各共电极电压驱动信号相同。
