Description

显示面板、显示装置及像素驱动方法 技术领域
本发明的实施例涉及显示技术领域,特别涉及一种用于3D显示的显示面板、显示装置和像素驱动方法。
背景技术
与平面显示装置相比,3D(3-Dimension)显示装置的显示画面更加立体逼真,用户体验效果更好,因此受到越来越多用户的喜爱。3D显示的的基本原理是:通过特殊设计的显示装置,使人的左眼和右眼分别接收不同的画面,然后通过观看者的大脑对接收的画面进行叠加,从而产生立体的显示画面。
在3D显示技术中,存在一种利用光栅进行3D显示的技术,其中,在显示面板前面设置光栅,利用光栅的透光部分和遮光部分,使显示面板上对应透光部分和遮光部分的像素单元发出的光分别进入人的左眼和右眼,产生视觉差异,从而感受到3D图像。在这种技术中,理想的情况是,光栅的遮光部分应当100%不透光,从而左右眼视图不会出现串扰而影响立体显示的效果。但是,实际上,由于光栅材料的局限性,光栅的遮光部分会有一定程度的漏光,造成左右眼视图存在一定串扰而影响立体显示的效果。因此,需要避免或减轻这种串扰对显示性能的影响。

具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述。以下实施例用于示例说明本发明,但不用来限制本发明的范围。
图1示出了根据本发明的一个实施例的显示面板中的像素阵列的示意图,为便于说明,没有示出显示面板的其它结构。如图1所示,显示面板包括排成行和列的多个像素单元,每个像素单元由红色亚像素R、绿色亚像素G和蓝色亚像素B三个亚像素构成。相邻列的像素单元分别用作左眼像素单元和右眼像素单元。例如,在图1中,由红色亚像素R1、绿色亚像素G1和蓝色亚像素B1构成的像素单元沿页面的竖向排成一列,用作左眼像素单元以显示左眼视图;而由红色亚像素R2、绿色亚像素G2和蓝色亚像素B2构成的像素单元沿页面的 竖向排成一列,用作右眼像素单元以显示右眼视图。左眼像素单元列和右眼像素单元列交替排列,彼此相邻。具体地,图1所示的第一列像素单元为左眼像素单元,第二列像素单元为右眼像素单元,第三列像素单元为左眼像素单元,第四列像素单元为右眼像素单元……,以此类推,构成整体像素阵列。
此外,根据图1所示的实施例,在相邻列的像素单元的亚像素之间设置有中间亚像素N,所述中间亚像素N的亮度值设为零(在图中显示为黑色的亚像素)。具体地,第一列像素单元的绿色亚像素G1和第二列像素单元的红色亚像素R2之间设置有中间亚像素N,第一列像素单元的蓝色亚像素B1和第二列像素单元的绿色亚像素G2之间也设置有中间亚像素N。类似地,第二列像素单元的红色亚像素R2和第三列像素单元的红色亚像素R1之间设置有中间亚像素N,第二列像素单元的蓝色亚像素B2和第三列像素单元的蓝色亚像素B1之间也设置有中间亚像素N。第三列像素单元和第四列像素单元、第四列像素单元和第五列像素单元以及后续的相邻列的像素单元的亚像素之间都设置有中间亚像素N。
根据本发明的该实施例,如上所述,在相邻列的像素单元的亚像素之间设置中间亚像素N,并将其亮度值例如灰阶设置为零或接近零。由于中间亚像素的亮度值设为零,在显示时,中间亚像素不发光,从而在物理上将相邻列的像素单元隔开。由于相邻列的像素单元分别为左眼像素单元和右眼像素单元,从而中间亚像素在物理上将左右眼像素单元隔开,从而,避免了左右眼视图产生串扰,影响立体显示效果。
根据一个具体的实施例,所述中间亚像素可以由黑色遮光材料制成。
另外,根据如图1所示的实施例,每个像素单元包括红色亚像素R、绿色亚像素G和蓝色亚像素B三个亚像素,所述三个亚像素排列成品字形结构,并且,每一列的各个像素单元的亚像素排列成相同的品字形结构,相邻列的像素单元中的亚像素排列成相互倒置的品字形结构。具体地,参见图1,在左眼像素单元例如第一列像素单元中,各个像素单元中的红色亚像素R1、绿色亚像素G1和蓝色亚像素B1排列成相同的品字形结构。在右眼像素单元如第二列像素单元中,各个像素单元中的红色亚像素R2、绿色亚像素G2和蓝色亚像素B2也排列成相同的品字形结构。但是,如图1所示,第一列的各个像素单元的亚像素排列成倒置的品字形结构,第二列的像素单元的亚像素排列成正的品字形结构。这样排列的好处是,可以均匀地、紧凑地排列亚像素,增加像素密度, 提高分辨率。但是,本领域技术人员应当理解,本发明的构思也可以应用于其他的亚像素排列结构。
此外,本领域技术人员应当理解,应用本发明构思的显示面板可以为液晶显示面板、OLED显示面板、等离子显示面板等类型,并且,本发明的显示面板可以包括阵列基板、TFT、彩膜基板、像素电极、栅线、数据线等其它必要的结构。
图2示出了覆盖有光栅装置1的图1的像素阵列的示意图。如图2所示,光栅装置1包括交替排列的透光部分1a和遮光部分1b,所述透光部分1a和遮光部分1b分别对应左眼像素单元和右眼像素单元。这样,通过光栅装置1的分光作用,左眼像素单元和右眼像素单元发出的光分别进入观看者的左眼和右眼,形成左眼视图和右眼视图,并经人的大脑叠加和融合产生立体视图。
本发明实施例可以采用的光栅装置可以是液晶光栅、EC光栅(电致发光材料制成的光栅)、光栅挡板等已知的光栅类型。如前所述,由于光栅材料的局限性,光栅的遮光部分会有一定程度的漏光,造成左右眼视图存在一定串扰而影响立体显示的效果。本发明的实施例可以避免或减轻所述串扰。具体地,在显示面板中,在相邻列的像素单元(即,左眼像素单元和右眼像素单元)的亚像素之间设置中间亚像素,并将其亮度值例如灰阶设置为零或接近零。由于中间亚像素在物理上将左右眼像素单元隔开,从而,参见图1和2,即使光栅1的遮光部分1b有一定程度的漏光,由于中间亚像素的隔离作用,也能避免左右眼像素单元的串扰。因此,根据本发明实施例的显示装置,能够提高立体显示效果。
图2只是示意地示出了显示装置的像素阵列和光栅装置。本领域技术人员应当理解,应用本发明构思的显示装置除了显示面板、光栅装置外可以包括背光组件等其它附加的结构。显示装置的示例可以包括台式电脑、笔记本电脑、平板电脑、电视机、手机、数码相框、导航仪等各种具有显示功能的装置。
本发明另一方面的实施例提供了一种用于补偿3D显示装置中的图像串扰的像素驱动方法。如前所述,由于光栅的遮光部有一定的透光率,因此被遮光部遮挡的左眼像素单元或右眼像素单元也会透过光栅发光,对没有被遮挡的另一像素单元的输出亮度产生串扰。如果不加以调整,实际输出亮度值会偏离预设的亮度值,造成显示的图像偏离理想图像。因此,需要预先对左右眼像素单元的预设输入亮度值进行调整,使得实际输出的亮度值接近或等于预设的输入 亮度值。
为此,本发明的实施例提出了一种例如用于如图2所示的显示装置的像素驱动方法,所述方法包括步骤:
确定输入左眼像素单元和右眼像素单元的各亚像素的预设的输入亮度值;
调整输入左眼像素单元和右眼像素单元的各亚像素的预设的输入亮度值,得到实际输入亮度值;和
将调整后的实际输入亮度值输入左眼像素单元和右眼像素单元的各亚像素,使得实际输出亮度值接近或等于预设的输入亮度值。
以图1的像素阵列为例,图3a-3b是分别示出图1所示的像素阵列中的两个相邻的左右眼像素单元的输入亮度值和输出亮度值的示意图。以蓝色亚像素为例,在图3a中,左眼像素单元中蓝色亚像素的预设的输入亮度值为L1,右眼像素单元中蓝色亚像素的预设的输入亮度值为L2;在图3b中,L’1为根据预设的输入亮度值L1,左眼像素单元中的蓝色亚像素透过光栅装置后的输出亮度值,L’2为根据预设的输入亮度值L2,右眼像素单元中的蓝色亚像素透过光栅装置后的输出亮度值。假定光栅材料的透光率的倒数为CR。
如图3a-3b所示,以蓝色亚像素为例,根据一个实施例,按照如下公式计算左眼像素单元中蓝色亚像素的实际输入亮度值L1’和右眼像素单元中蓝色亚像素的实际输入亮度值为L2’:
当L’1>L’2,且L’1/L’2≤CR或L’2>L’1且L’2/L’1≤CR时,
L1’+L2’/CR=L1,L2’+L1’/CR=L2   (1)
当L’1>L’2,且L’1/L’2>CR时,L1’=L1,L2’=L0   (2)
当L’2>L’1,且L’2/L’1>CR时,L2’=L2,L1’=L0   (3)
其中,L0表示输出亮度值为零。根据光栅的制作材料不同,CR的取值不同,通常CR取值范围可以为5-100。
根据上述公式确定左眼像素单元中蓝色亚像素的实际输入亮度值L1’和右眼像素单元中蓝色亚像素的实际输入亮度值为L2’的具体的过程如下:
首先,确定在预设的输入亮度值L1和L2下经光栅输出的左右眼像素的输出亮度值的比值L’1/L’2或L’1/L’2,其中,以L’1和L’2中较大的数作为被除数,将L’1/L’2或L’1/L’2的值与光栅的透光率的倒数CR进行比较;
然后,根据比较的结果确定实际输入值L1’和L2’。具体地,当L’1/L’ 2或L’1/L’2的值不大于光栅材料的透光率的倒数CR时,应用公式(1)计算L1’和L2’;
当L’1/L’2的值大于光栅材料的透光率的倒数CR时,应用公式(2)确定L1’和L2’;
当L’2/L’1的值大于光栅材料的透光率的倒数CR时,应用公式(3)确定L1’和L2’。
以上是以蓝色亚像素为例来说明本发明的像素驱动方法。对于红色亚像素和绿色亚像素,计算方法相同。并且,以上以图1和2的像素阵列为例来说明本发明的像素驱动方法,但是对于其它像素阵列,只要以相邻列划分左眼像素单元和右眼像素单元,也适用于本发明的像素驱动方法。
以下结合图4-7以具体的例子来说明上述的调整方法。
图4是示出图3a的左右眼像素单元的预设输入亮度值的示例的示意图。如图4所示,以蓝色亚像素为例,左眼像素单元预设的输入亮度值L1为120,右眼像素单元预设的输入亮度值L2为150。
图5a-5b是显示图4的右眼像素单元经由光栅输出的输出亮度值发生变化的示意图。如图5a所示,在图4的像素单元前加上光栅装置,并且光栅的遮光部分对应右眼像素单元,假定光栅遮光部分的透光率为10%,则CR等于10。此时,由于光栅的作用,如图5b所示,左眼像素单元输出的亮度值L’1不变,等于输入亮度值,即L’1=120,右眼像素单元输出的亮度值L’2变为预设的输入亮度值L2的10%,即L’2=15。
图6a-6b是显示图4的左眼像素单元经由光栅输出的输出亮度值发生变化的示意图。如图6a所示,在图4的像素单元前加上光栅装置,并且光栅的遮光部分对应左眼像素单元,假定光栅遮光部分的透光率为10%,则CR等于10。此时,由于光栅的作用,如图6b所示,左眼像素单元输出的亮度值L’1变为预设的输入亮度值L1的10%,即L’1=12;右眼像素单元输出的亮度值L’2不变,等于输入亮度值,即L’2=150。
图7a是显示根据本发明的像素驱动方法对图5的左右眼像素单元的预设输入亮度值进行调整后的实际输入亮度值的示意图。具体地,如图7a所示,光栅的遮光部分对应右眼像素单元,假定光栅遮光部分的透光率为10%,则CR等于10。按照给定的预设输入亮度值L1=120和L2=150,可以得出经光栅输出后L’ 1=120,L’2=15。此时,如果不调整输入亮度值,则透过光栅后蓝色亚像素的输出亮度值L’1和L’2叠加,一定超出了预设的输入亮度值120,因此不能产生预期的显示效果。
相反,根据本发明的像素驱动方法,在上述输入亮度值L1=120和L2=150下,计算L’1/L’2=120/15=8,即L’1/L’2<CR。因此,需要根据公式(1)来确定左右眼像素单元的实际输入亮度值L1’和L2’。因此,将L1=120、L2=150、CR=10分别代入公式(1),经计算方程式,得到L1’≈106,L2’≈139。因此,理想地,左眼像素单元的蓝色亚像素的输入亮度值应调整为近似106,右眼像素单元的蓝色亚像素的输入亮度值应调整为近似139。这样,最终左右眼像素单元的蓝色亚像素的叠加产生的输出为106+139/10≈120,接近预设的左眼像素单元的蓝色亚像素的输入亮度值120,从而,根据本发明的像素驱动方法,防止了由于光栅漏光产生串扰而导致蓝色亚像素的输出亮度值偏离预设输入值。
在实际调整时,实际输入亮度值接近上述计算值即可。例如,如图7a所示,左眼像素单元实际输入亮度值L1’为110,右眼像素单元实际输入亮度值L2’为130;这样,经过光栅装置后,如图7b所示,左眼像素单元实际输出亮度值为110,右眼像素单元实际输出亮度值为13,最终左右眼像素单元的蓝色亚像素的叠加产生的输出为110+13/123,接近预设的左眼像素单元的蓝色亚像素的输入亮度值120,从而,同样防止了由于光栅漏光产生串扰而导致蓝色亚像素的输出亮度值偏离预设输入值。
此外,对于图6所示的情况,可以确定L’2/L’1=150/12=12.5,即L’2/L’1>CR。因此,需要根据公式(3)来确定左右眼像素单元的实际输入亮度值L1’和L2’。具体地,根据公式(3),得到左眼像素单元中蓝色亚像素实际输入亮度值L1’=0,右眼像素单元中蓝色亚像素实际输入亮度值L2’=150。
以上示例中,假设光栅材料的透光率为10%,因此,CR取值为10。实际中,光栅材料的透光率是变化的,因此,CR的取值范围也是变化的。通常,CR选值范围为5-100。
以上说明了调整输入左眼像素单元和右眼像素单元的各亚像素的预设的输入亮度值的例子,本领域技术人员可以设想其它的方式来调整预设的输入亮 度值,只要使得调整后的实际输出亮度值接近或等于预设的输入亮度值即可。
如上所述,根据本发明的像素驱动方法,如果光栅屏蔽时具有漏光,能够降低由于光栅漏光引起的串扰的影响,从而提高显示装置的显示性能。
以上实施方式仅用于说明本发明,而并非对本发明的限制,有关技术领域的普通技术人员,在不脱离本发明的精神和范围的情况下,还可以做出各种变化和变型,因此所有等同的技术方案也属于本发明的范畴,本发明的专利保护范围应由权利要求限定。
