具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，相关领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“上”、“下”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
早期的3D显示装置需要使用者佩戴相应的3D眼镜，近年来裸眼3D显示器件备受关注。实现裸眼3D显示的装置一般有两种类型：狭缝光栅式3D显示装置和微透镜阵列式3D显示装置。狭缝光栅式又称为视差屏障，通常使用开关液晶屏、高分子液晶层和偏振膜实现，通过控制开关液晶屏中上、下基板的电极之间的电压差，使高分子液晶层中液晶分子发生旋转，形成不透明条纹，即视差障栅。当液晶屏开关打开时，在这些视差障栅的作用下，左 眼能够看到的图像只能由左眼看到，而右眼将被遮挡；右眼能够看到的图像只能由右眼看到，而左眼将被遮挡。当液晶屏开关关闭时，显示面板不会出现视差障栅，从而成为普通的2D显示器。
在三维显示模式下，如图1所示的后置光栅形成发光区域和黑色区域，在前置的液晶显示面板中与同一发光区域对应的各像素显示不同的灰阶信息，使相邻的两个视点之间接收具有不同信息的图像，眼睛分别位于两个视点时会接收两幅不同的图像，再由两眼的视觉汇合到大脑中成为一个像，从而产生了立体视觉以实现裸眼三维显示。在图1中以一个发光区域对应两个像素为例示出了实现两视点的情况，其中以“1”和“2”区分不同视图，左眼通过后置光栅看到像素L1、L3和L5显示的视图1，右眼通过后置光栅看到像素L2、L4和L6显示的视图2。
发明人注意到，这种三维显示装置通常存在连续观看角度小，串扰高的问题。例如，如图2所示，当观看者的右眼位于位置A时，右眼仅能通过液晶显示面板的像素L2看到视图2，无法看到视图1，定义该位置为最佳观看位置，由于液晶显示面板的像素所显示的视图不变，当观看者的右眼由位置A移动到位置B时，右眼既能通过液晶显示面板的像素L2看到视图2，又能通过液晶显示面板的像素L3看到视图1，此时进入到右眼的视图1形成了串扰。
本公开的实施例提供的一种三维显示装置的驱动方法，如图3所示，包括以下步骤：
S301、控制位于液晶显示面板下方的电致发光显示面板中排列的各第一亚像素以形成在行方向交替排布的发光区域和黑色区域；
S302、确定观看者的眼睛在液晶显示面板的显示面一侧的位置信息；
S303、根据从观看者的眼睛到电致发光显示面板中的各发光区域的光路径，确定液晶显示面板中与各发光区域对应的显示左眼视图的位置与显示右眼视图的位置；
S304、在三维显示模式下，控制在液晶显示面板中对应同一显示左眼视图的位置处的各第二亚像素显示相同的第一灰阶信息，控制对应同一显示右眼视图的位置处的各第二亚像素显示相同的第二灰阶信息，且对应同一显示三维视图的发光区域的第一灰阶信息与第二灰阶信息不同。
本公开实施例提供的上述驱动方法，可以根据观看者的眼睛当前所在位置确定出液晶显示面板显示左眼视图和右眼视图的位置，并在液晶显示面板 中控制对应同一左眼视图位置处的各第二亚像素进行相同视图的显示，控制对应同一右眼视图位置处的各第二亚像素进行相同视图的显示。以此方式，降低了在三维显示时进入到同一只眼中不同视图而形成的显示串扰。并且，可以根据观看者的眼睛当前所在位置对液晶显示面板中显示的眼睛视图的位置进行变换，从而增大连续观看的角度，可以达到全视角三维显示的效果。
例如，本公开实施例提供的上述驱动方法中的步骤S302确定观看者的眼睛在液晶显示面板的显示面一侧的位置信息，如图4所示，可以采用下述步骤实现：
S401、确定观看者在液晶显示面板前方是否满足设定的观看距离范围；若是，则执行步骤S402；若否，则退出流程；
例如，三维显示装置均会设置三维显示的最佳观看距离范围，例如3-5m，在观看者在此范围内可观看到三维显示效果，若不在此范围，则有可能观看不到三维显示效果。因此，在观看者处于能够观看到三维显示效果的观看距离范围内才执行下述视觉追踪的功能；
S402、如果确定观看者在液晶显示面板前方设定的观看距离范围内时，实时获取观看者左眼或右眼在与液晶显示面板平行的水平面内的坐标位置。
例如，可以通过诸如摄像头之类的图像获取装置获取观看者左眼或右眼在与液晶显示面板平行的水平面内的坐标位置。例如，可以以水平面内的某一点作为原点建立二维坐标系，以确定坐标位置；
S403、确定获取到的观看者左眼或右眼在水平面内的坐标位置的水平移动距离和水平移动方向；
S404、确定观看者左眼或右眼在与液晶显示面板平行的水平面内的坐标位置的水平移动距离是否大于预设值；若是，则执行步骤S405；若否，则返回步骤S402；若水平移动距离小于一预设值，则可认为视觉的移动过小，不会构成三维显示串扰；
S405、确定观看者左眼或右眼在与液晶显示面板平行的水平面内的坐标位置的水平移动距离大于预设值时，确定观看者的眼睛发生移动，并将观看者左眼或右眼在水平面内的坐标位置的水平移动距离和水平移动方向确定为观看者的眼睛在液晶显示面板的显示面一侧的位置信息。
例如，本公开实施例提供的上述驱动方法中的步骤S303根据从观看者的眼睛到电致发光显示面板中的各发光区域的光路径，确定液晶显示面板中与 各发光区域对应的显示左眼视图的位置与显示右眼视图的位置，可以包括：
在确定观看者的眼睛发生移动时，根据观看者左眼或右眼在水平面内的坐标位置的水平移动距离和水平移动方向，重新确定液晶显示面板中与各发光区域对应的显示左眼视图的位置与显示右眼视图的位置。
例如，根据观看者左眼或右眼在所述水平面内的坐标位置的水平移动距离和水平移动方向，重新确定液晶显示面板中与各所述发光区域对应的显示左眼视图的位置与显示右眼视图的位置，可以遵循如下规律：
在观看者的人眼眼睛发生移动后的各发光区域对应的显示左眼视图的位置与显示右眼视图的位置，相对于在观看者的眼睛发生移动前的各所述发光区域对应的显示左眼视图的位置与显示右眼视图的位置，向观看者的左眼或右眼的水平移动方向进行设定距离的平移。
例如，如图5所示，当人眼位于位置A，液晶显示面板中的DF区域显示与该眼对应的视图，位置A所对应的液晶显示面板中DF区域内的全部第二亚像素显示视图的灰阶信息应相同。当人眼移动到位置B时，液晶显示面板中的EG区域显示与该眼对应的视图，位置B所对应的液晶显示面板中EG区域内的全部第二亚像素显示视图的灰阶信息应相同，且与位置A所对应DF区域内的第二亚像素显示视图的灰阶信息相同。因此，为了使在人眼位置移动后，液晶显示面板中显示与该眼对应的视图的区域随之发生移动时，该区域内的第二亚像素显示视图的灰阶信息相同，在液晶显示面板的该区域应该包括多个第二亚像素。例如，液晶显示面板的分辨率应高于电致发光显示面板的分辨率，且液晶显示面板的分辨率越大越好，即液晶显示面板中的第二亚像素的数量应多于电致发光显示面板中的第一亚像素的数量。
基于上述分析，如图5所示，设定DF区域在水平方向的宽度为p，AB之间的距离为x，观看者左眼和右眼之间的瞳孔间距为L，电致发光显示面板与液晶显示面板之间的距离为h，观看者到液晶显示面板之间的观看距离为s。则可得到如下公式：p/L＝h/(h+s)；DE/x＝h/(h+s)，通过推导上述两个公式可得到DE＝px/L，其中，DE为显示视图的移动距离。
因此，本公开实施例提供的上述驱动方法中，在观看者的眼睛发生移动后的各发光区域对应的显示左眼视图的位置与显示右眼视图的位置，相对于在观看者的眼睛发生移动前的各所述发光区域对应的显示左眼视图的位置与显示右眼视图的位置，向观看者的左眼或右眼的水平移动方向进行设定距离 的平移，平移量可以按照以下方式实现：
按照下述公式确定各发光区域对应的显示左眼视图的位置与显示右眼视图的位置的平移距离y：y＝p*x/L，其中，p为各显示左眼视图或显示右眼视图的区域在水平方向的宽度，x为观看者左眼或右眼在水平面内的坐标位置的水平移动距离；L为观看者左眼和右眼之间的瞳孔间距。
例如，本公开实施例提供的上述驱动方法中的步骤S301控制电致发光显示面板中紧密排列的各第一亚像素形成在行方向交替排布的发光区域和黑色区域的同时，还可以包括：控制电致发光显示面板中紧密排列的各第一亚像素形成在列方向交替排布的发光区域和黑色区域。以此方式，在电致发光显示面板中发光区域和黑色区域的分布相对均匀，有利于形成的背光和光栅亮度分布均匀，可以减少颜色不均的问题。
例如，本公开实施例提供的驱动方法中可以采用电致发光显示面板实现视图的色度显示，即如图6所示，将液晶显示面板中的的色阻去除。这样可以提高三维显示装置中液晶显示面板的光透过率，降低功耗，提高显示亮度，并且，还有利于实现横纵屏兼容显示。例如，如图7所示，将电致发光显示面板的紧密排列的各第一亚像素设置为：相邻列的第一亚像素的发光颜色不同，同一列第一亚像素的发光颜色相同。
在本公开实施例提供的上述驱动方法中的控制电致发光显示面板中紧密排列的各第一亚像素形成在行方向和列方向均交替排布的发光区域和黑色区域，可以采用如下方式：
如图8所示，控制电致发光显示面板中同一行内各第一亚像素间隔开启，且同一列内各第一亚像素间隔开启，形成交替排布的发光区域和黑色区域。以此方式，在电致发光显示面板中形成品字形的三个位置为发光颜色不同的第一亚像素，这样有利于形成的背光和光栅亮度分布均匀，可以减少颜色不均的问题，也有利于三维显示装置实现横纵屏兼容显示。
本公开实施例提供的上述三维显示装置的驱动方法还可以实现三维显示装置的二维显示模式，例如，该驱动方法还可以包括以下步骤：
在二维显示模式下，控制对应同一发光区域的显示左眼视图的位置处的各第二亚像素与显示右眼视图的位置处的各第二亚像素显示相同的灰阶信息，即可使人的眼睛观看到相同的两幅视图，从而实现二维显示。
基于同一发明构思，本公开实施例还提供了一种三维显示装置，该显示 装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。由于该装置解决问题的原理与前述一种驱动方法相似，因此该装置的实施可以参见方法的实施，重复之处不再赘述。
本公开实施例提供的一种三维显示装置，如图6所示，包括：液晶显示面板100，设置在液晶显示面板100下方的电致发光显示面板200，视觉追踪装置(图6中未示出)，以及处理装置(图6中未示出)。如图7所示，电致发光显示面板200具有依序排列的多个第一亚像素。如图8所示，各第一亚像素形成在行方向交替排布的发光区域和黑色区域。
视觉追踪装置，用于确定观看者的眼睛在液晶显示面板100的显示面一侧的位置信息。
处理装置，用于根据从观看者的眼睛到电致发光显示面板200中的各发光区域的光路径，确定液晶显示面板100中与各发光区域对应的显示左眼视图的位置与显示右眼视图的位置。
液晶显示面板100具有呈阵列排布的多个第二亚像素。在三维显示模式下，对应同一显示左眼视图的位置处的各第二亚像素显示相同的第一灰阶信息。对应同一显示右眼视图的位置处的各第二亚像素显示相同的第二灰阶信息。且对应同一显示三维视图的发光区域的第一灰阶信息与第二灰阶信息不同。
例如，本公开实施例提供的上述三维显示装置需要进行二维图像显示时，即在二维显示模式下，对应同一发光区域的所述显示左眼视图的位置处的各第二亚像素与显示右眼视图的位置处的各第二亚像素显示相同的灰阶信息，即可使人的眼睛观看到相同的两幅视图，从而实现二维显示。
例如，本公开实施例提供的上述三维显示装置中，如图8所示，各第一亚像素形成的发光区域和黑色区域在列方向也交替排布。此时，在电致发光显示面板中发光区域和黑色区域的分布相对均匀，有利于形成的背光和光栅亮度分布均匀，可以减少颜色不均的问题。
例如，本公开实施例提供的上述三维显示装置中，电致发光显示面板200中相邻列的第一亚像素的发光颜色不同，同一列第一亚像素的发光颜色相同；且液晶显示面板100中的各第二亚像素无色阻。这样可以提高三维显示装置中液晶显示面板100的光透过率，以降低功耗，提高显示亮度，并且，还有 利于实现横纵屏兼容显示。
例如，在本公开实施例提供的上述三维显示装置中，液晶显示面板的分辨率大于所述电致发光显示面板的分辨率，且液晶显示面板的分辨率越大越好。以使得在人眼位置移动后，液晶显示面板中显示与该眼对应的视图的区域随之发生移动时，该区域内的第二亚像素显示视图的灰阶信息相同，因此，在液晶显示面板中应该由多个第二亚像素包含于该区域。
本公开实施例提供的一种三维显示装置及其驱动方法，包括：控制位于液晶显示面板下方的电致发光显示面板中紧密排列的各第一亚像素形成在行方向交替排布的发光区域和黑色区域，以构成后置光栅；确定观看者的眼睛在液晶显示面板的显示面一侧的位置信息；根据从观看者的眼睛到电致发光显示面板中的各发光区域的光路径，确定液晶显示面板中与各发光区域对应的显示左眼视图的位置与显示右眼视图的位置。在三维显示模式下，控制液晶显示面板中对应同一显示左眼视图的位置处的各第二亚像素显示相同的第一灰阶信息，控制液晶显示面板中对应同一显示右眼视图的位置处的各第二亚像素显示相同的第二灰阶信息，且对应同一显示三维视图的发光区域的第一灰阶信息与第二灰阶信息不同。由于根据观看者的眼睛的当前所在位置确定出液晶显示面板显示左眼视图和右眼视图的位置，并在液晶显示面板中控制对应同一左眼视图位置处的各第二亚像素进行相同视图的显示，控制对应同一右眼视图位置处的各第二亚像素进行相同视图的显示，从而降低了在三维显示时进入到同一只眼中不同视图而形成的显示串扰。并且，可以根据观看者的眼睛当前所在位置对液晶显示面板中显示的眼睛视图的位置进行变换，从而增大连续观看的角度，可以达到全视角三维显示的效果。
以上所述，仅为本公开的示例性实施例，但本公开的保护范围并不局限于此，任何熟悉本技术领域的普通技术人员在本公开的实施例揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。
