目前，光场显示为解决用户眼睛疲劳和眩晕提供了一个可行的方法，通过模拟自然3D物体的光场，实现自然的3D显示，降低了人眼的疲劳和眩晕。实现光场显示的方法除了全息显示以外，主要有采用微透镜阵列的集成成像显示。如图1所示，可以在显示元件的前方叠加一层微透镜阵列，通过在显示元件上渲染集成成像的显示图像，通过微透镜阵列对各个方向光线的控制，形成自然的3D显示。
如图1所示，在集成成像的3D显示系统中，在显示空间内，显示面板10’上的像素11’所携带的信息被微透镜阵列20’中的微透镜成像成为三维显示物体30’。在一般的集成成像三维显示系统中，一个微透镜下对应多个由红色子像素(R子像素)、绿色子像素(G子像素)和蓝色子像素(B子像素)组成的像素。如图2所示，为相关技术中的一个显示面板10’，一个微透镜下对应8×8个像素11’。其中，每个像素11’由RGB三个子像素构成，则一个微透镜的尺寸对应长度方向24个子像素，宽度方向24个子像素。8×8个像素11’构成3D图像单元，每一个像素11’对应一个光线的方向，因此8×8个像素构成了64个光线方向，即提供了64个视点。
集成成像的3D图像分辨率取决于微透镜的尺寸，为了提高3D图像分辨率，需要减小微透镜的尺寸。但是，减小微透镜的尺寸将不能保证视点的数量，从而会影响光场3D显示的立体效果。目前，采用普通RGB像素排列方式集成成像显示的微透镜尺寸较大(如上述所述，对应24×24个子像素)，3D分辨率较低，无法满足人眼的视觉要求。因此，在保证有足够多的视点实现光场3D显示的基础上，如何提高3D显示成像的分辨率是本领域有待解决的一个难题。
请结合图3和图4以理解，本实施案例提供一种显示装置。所述显示装置包括显示面板10和位于所述显示面板10的出光侧的微透镜阵列20(图3中未标示)。所述显示面板10设有多个像素岛，所述微透镜阵列20设有与所述像素岛一一对应的多个微透镜单元。其中，每个微透镜单元在该显示面板10上的正投影与对应的一个像素岛所在的区域重合，或者位于对应的一个像素岛所在的区域内。也即是，每个微透镜单元的尺寸可以小于或等于对应的一个像素岛的尺寸。
每个所述像素岛包括阵列排布的多个子像素，同一所述像素岛内的子像素显示的颜色相同。所述像素岛包括显示第一颜色的第一像素岛11、显示第二颜色的第二像素岛12和显示第三颜色的第三像素岛13。相应的，如图4所示，该微透镜阵列20包括：与该第一像素岛11对应的第一微透镜单元21，与该第二像素岛12对应的第二微透镜单元22，以及与该第三像素岛13对应的第三微透镜单元23。
其中，彼此相邻的所述第一像素岛11、所述第二像素岛12和所述第三像素岛13形成一重复单元，在同一所述重复单元中，所述第一像素岛11中的第一子像素、所述第二像素岛12中的第二子像素和所述第三像素岛13中的第三子像素分别位于三角形的三个顶点。并且，该第一子像素相对于第一像素岛11对应的所述微透镜单元的位置，该第二子像素相对于第二像素岛12对应的所述微透镜单元的位置，以及该第三子像素相对于第三像素岛13对应的所述微透镜单元的位置相同。
图5是本公开一示例性实施例的显示面板的局部结构示意图。如图5所示，该第一像素岛11用于显示的第一颜色为红色(red，R)，第二像素岛12用于显示的第二颜色为绿色(green，G)，第三像素岛13用于显示的第三颜色为蓝色(blue，B)。并且，该第一像素岛11中第一行第一列的第一子像素R，第二像素岛12中第一行第一列的第一子像素G，以及第三像素岛13中第一行第一列的第一子像素B分别位于三角形的三个顶点。
也就是说，每个所述像素岛对应一个所述微透镜单元进行光束方向的控制，所述像素岛中每个子像素对应一个方向的光线，所述显示面板10和所述微透镜阵列共同作用以实现集成成像的3D显示。基于所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，且在同一 所述重复单元中，所述第一像素岛11中、所述第二像素岛12中和所述第三像素岛13中相对于各自所述微透镜单元的位置相同的三个子像素分别位于三角形的三个顶点的设置，能够在保证长度方向形成多个视点方向的3D图像的基础上提高集成成像的分辨率。而且，利用所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，可以减小微透镜尺寸，能够改善对作为3D显示装置对2D显示分辨率的影响。
可选地，参考图5，在每一所述像素岛中，长度方向X的所述子像素的数量为2k个，且长度方向X的所述子像素的数量与宽度方向Y的所述子像素的数量之比为2i：1。其中，k为大于或等于2的整数，i为大于或等于1的整数。即，在每一所述像素岛长度方向X的子像素最少为4、宽度方向Y的子像素最少为2，每一所述像素岛中至少大于8个子像素数量，以形成长度方向至少4个视角，宽度方向至少2个视角的3D图像。例如，在图3和图5所示的示例中，每个像素岛中，长度方向的子像素的个数为8，宽度方向的子像素的个数为4，即每个像素岛包括8×4个子像素。
在本公开实施例中，该长度方向X可以平行于栅线的延伸方向，宽度方向Y可以平行于数据线的延伸方向。
在相关技术中，在普通的RGB子像素依次分布排列的情况下，由于彩膜的最小间隔是一个子像素的大小，在此基础上，如果要提升彩膜的分辨率，会提升彩膜的制作难度，对良率产生影响。而在本实施例中，彩膜的最小间隔是一个单色像素岛的大小。而且，由于单色像素岛中的子像素的数量大于8个，从而可以在较大的单位尺寸上制作彩膜，从而降低彩膜的制作工艺要求，提高良品率，更进一步降低了提升彩膜的分辨率的制作难度。
所述微透镜单元的大小与形状均与所述像素岛的大小与形状一致。所述像素岛与所述微透镜单元的形状均为矩形。所述微透镜阵列起着控制光线方向的作用。应理解的是，该像素岛和微透镜单元的形状还可以为除矩形之外的其他形状，例如，还可以为圆形、菱形或正六边形等。
可选地，所述微透镜单元的节距P的计算公式如下：
P＝(N×T×Px)/(T+Px)；
所述微透镜单元的曲率半径r的计算公式如下：
r＝(Px×L(N-1))/T；
所述微透镜单元与所述显示面板之间的距离(也可以称为微透镜单元的放置高度)h的计算公式如下：
h＝(L×Px)/T；
所述微透镜单元的厚度d的计算公式如下：
d＝n×r/(n-1)-n×h；
所述微透镜单元的宽度w的计算公式如下：
w＝(L×N×Px)/(L+h)；
其中，所述子像素的宽度为Px，所述微透镜单元的材料的折射率为n，L为预设的观看距离，T为预设的双眼瞳距，N为每个像素岛包括的子像素的个数，也可以称为视点数。
应理解的是，子像素的宽度方向平行于微透镜单元的宽度方向，且平行于栅线的延伸方向。并且，每个子像素的长度与宽度的比值可以为3:1。上述微透镜单元与所述显示面板之间的距离h可以是指：微透镜的光心与显示面板的出光面之间的距离。微透镜的光心也可以理解为微透镜的中心。上述预设的观看距离L可以是根据显示装置的应用场景确定的。例如，若该显示装置为手机，则该预设的观看距离L的取值范围可以为200毫米(mm)至350mm。若该显示装置为电视，则该预设的观看距离L的取值范围可以为1米(m)至3m。预设的双眼瞳距T的取值范围为55mm至75mm，例如可以取平均值65mm。
可选地，在同一所述重复单元中，所述第一像素岛11中的第一子像素、所述第二像素岛12中的第二子像素和所述第三像素岛13中的第三子像素分别位于等腰三角形的三个顶点。
从图3和图5中可以看出，所述重复单元中彼此相邻的所述第一像素岛11、所述第二像素岛12和所述第三像素岛13，分布于相邻的上下两行，且呈相错排列。因此，当上一行中的所述第一像素岛11位于下一行相对应位置的所述第二像素岛12和所述第三像素岛13的正中，即形成所述第一像素岛11中、所述第二像素岛12中和所述第三像素岛13中相对于各自所述微透镜的位置相同的三个子像素分别位于等腰三角形的三个顶点，以方便显示面板的制作。
可选地，所述显示装置还包括控制单元40和渲染单元50，所述控制单元40与所述渲染单元50电连接，且所述控制单元40用于控制所述渲染单元50进行图像渲染，所述像素岛中的每一子像素均与所述渲染单元50电连接。
其中，该渲染单元50可以为图形处理器(graphics processing unit，GPU)或者中央处理器(central processing unit，CPU)。并且，该渲染单元50可以通过驱动电路(例如源极驱动电路)与各个子像素连接。该控制单元40可以为CPU。在本公开实施例中，该渲染单元50与该控制单元40可以相互独立设置，也可以集成设置。
请复参阅图3和图5，在本实施例中，显示面板10采用8K(7680×4320)的RGB子像素的面板，实际整个显示面板10的长度方向的子像素数量为(7680×3)。显示面板10中每个所述第一像素岛11、所述第二像素岛12和所述第三像素岛13的大小均设置为8×4个单色子像素，代表了可渲染8×4＝32个方向的图像，即长度方向(也称为横向)8个视点，宽度方向(也称为纵向)4个视点，共形成32个视点的集成成像3D显示。
每个重复单元中，形成一个视点的彩色融合像素的RGB三个子像素为显示红色的第一像素岛11中、显示绿色的第二像素岛12中和显示蓝色的第三像素岛13中相对于各自所述微透镜单元的位置相同的三个子像素。RGB三个子像素位于三角形的三个顶点设置，整个显示面板10的彩色融合像素共同组成各个视点的彩色3D图像。并且，通过使彩色融合像素中RGB三个子像素位于三角形的三个顶点，可以确保显示面板中形成的彩色融合像素在横纵方向的尺寸较为均衡。
此时，如图5所示，相邻两个彩色融合像素14的长度方向X的间距为12个子像素的宽度，宽度方向Y的间距为8个子像素的长度，所以能实现的3D图像的长度方向X的分辨率为7680*3/12＝1960，宽度方向Y的分辨率为4320/8＝540。
而相关技术中的显示面板10的普通的RGB间隔子像素排列的方式，每个微透镜对应8×8个像素，其长度方向具有8个视点，纵向具有8个视点。其能实现的3D图像的长度方向的分辨率为7680/8＝960，宽度方向的分辨率为4320/8＝540。
可以看出，本公开的3D图像在长度方向视点数目相同的情况下，具有更高的长度方向的分辨率。需要解释的是，一般人眼对长度方向的分辨率提升更为敏感，因此，在长度方向上的分辨率的提升，对整体的视觉上的分辨率的提升的作用更大。
基于同一发明构思，本公开的实施例提供一种显示装置的显示方法。所述显示方法包括：
在每个显示周期内，逐行驱动所述显示装置包括的多行像素进行显示。
其中，每个像素包括：同一所述重复单元中的所述第一像素岛中的第一子像素、所述第二像素岛中的第二子像素和所述第三像素岛中的第三子像素。
通过该显示方法显示的图像为3D图像。这样，控制单元控制渲染单元对重复单元的像素岛中的子像素按照相应的灰阶进行渲染，以便形成不同方向的图像，形成集成成像的3D图像。
更进一步，本公开实施例提供的显示方法可以采用时分复用方式复用所述像素岛中的子像素进行显示，以进一步提升3D图像显示的分辨率。
可选的，该每个显示周期中可以包括多个时序，该多个时序中任意两个时序驱动显示的像素不同，且任意两个时序驱动显示的像素复用至少一个所述像素岛中的子像素。
示例的，每个显示周期中可以包括2m、或者3m、或者6m个时序，其中m为大于等于1的正整数。并且，每一时序的图像刷新频率大于F，F为人眼不能感知到图像的闪烁时的刷新频率。由于人眼不能感知到图像的闪烁时的刷新频率一般为大于30Hz，因此该F可以大于或等于30Hz。同时，为了让显示装置正确显示所需图像，控制单元控制渲染单元保证在正确的时序对3D图像进行渲染进而显示在显示面板上。
作为一种可选的实现方式，如图6所示，为本实施例的另一3D图像显示方法的显示面板10的显示示意图。该显示方法可以通过时分复用相邻子像素的方法进一步进行长度方向X的3D显示分辨率的提升。在该实现方式中，每个显示周期中包括第一时序、第二时序和第三时序共3个时序。其中，第一时序中驱动显示的第一像素与第二时序中驱动显示的第二像素复用至少一个像素岛中的子像素，该第二像素与第三时序中驱动显示的第三像素复用至少一个像素岛中的子像素，并且，该第一像素、第二像素和第三像素沿平行于栅线的方向(即该长度方向X)排列。
本实施例中所提出的基于所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，可以采用高刷新率的显示面板10，通过沿长度方向X排列的像素时分复用相邻子像素的方法，进一步进 行长度方向X的3D显示分辨率的提升。
从图6中可看到，假设第一时序为时序1，第二时序为时序2，则在时序1和时序2复用了相同的R、G和B子像素。例如，按照由左至右的顺序，第一时序：时序1中的第一个第一像素和第二时序：时序2中的第一个第二像素共用了R和B子像素。该时序2中第一个第二像素还和时序1中第二个第一像素共用了G子像素。应理解的是，就相邻的两个像素来说，时序1中第一个第一像素和时序2中第一个第二像素共用了R和B子像素，而该相邻的两个像素并未共用G子像素。即，在相邻的时序的图像中，空间相邻的两个像素采用的第一像素岛11中的第一子像素、第二像素岛12中的第二子像素和第三像素岛13中的第三子像素部分共用，从而实现时分复用，并提高分辨率。
同理，如图6所示，假设第三时序为时序3，则在时序2和时序3时复用了R、B和G子像素，时序1和时序3时复用R、G和B子像素。例如，时序3中第一个第三像素和时序2中第一个第二像素共用了G和B子像素，且与时序2中第二个第二像素共用了R子像素。该时序3中第一个第三像素还和时序1中第二个第一像素共用了G和R子像素。从图6可以看出，上述第一像素，第二像素和第三像素沿长度方向X排列。
若显示面板中每个像素岛均包括8×4个单色子像素，则控制单元控制渲染单元分别在不同时序进行相应的3D图像的渲染，这样复用后在最终的长度方向X上，相邻两个彩色融合像素的间距为4个子像素。相比未复用的情况，长度方向的分辨率提升了3倍。由于在一个显示周期包含3个时序，此时要求显示面板10具有至少90Hz的刷新率，以保证每个时序的刷新率不小于30Hz，在观看时不发生图像的闪烁。
作为另一种可选的实现方式，如图7所示，为本实施例的又一3D图像显示方法的显示面板10的显示示意图。该显示方法可以通过时分复用相邻子像素的方法进一步进行宽度方向Y的3D显示分辨率的提升。在该实现方式中，每个显示周期中包括第一时序和第二时序共2个时序。其中，第一时序中驱动显示的第一像素与第二时序中驱动显示的第二像素复用一个或两个像素岛中的子像素，且第一像素和第二像素沿平行于数据线的方向(即宽度方向Y)排列。
本实施例中所提出的基于所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，可以采用高刷新率的显示 面板10，通过沿宽度方向Y排列的像素时分复用相邻子像素的方法，进一步进行宽度方向Y的3D显示分辨率的提升。
从图7中可看到，在时序1和时序2时复用了相同的R、G和B子像素。例如，时序1中第一个第一像素和时序2中第一个第二像素复用了G和B子像素，该时序2中第一个第二像素还与时序1中第二个第一像素复用了R子像素。并且，上述第一像素和第二像素沿宽度方向Y排列。
若显示面板中每个像素岛均包括8×4个单色子像素，则控制单元控制渲染单元分别在不同时序进行相应的3D图像的渲染，这样复用后在最终的宽度方向Y上，相邻的彩色融合像素的间距为4个子像素。相比未复用的情况，宽度方向Y的分辨率提升了2倍。由于此时在一个显示周期包含2个时序，此时要求显示面板10具有至少60Hz的刷新率，以保证每个时序的刷新率不小于30Hz，在观看时不发生图像的闪烁。
作为再一种可选的实现方式，如图8所示，为本实施例的再一3D图像显示方法的显示面板10的显示示意图，为了同时提高长度方向X和宽度方向Y的3D显示分辨率，该显示方法采用时分复用同时对长度方向排列的子像素和宽度方向排列的子像素进行复用。在该实现方式中，每个显示周期中包括第一时序、第二时序、第三时序、第四时序、第五时序和第六时序共6个时序。
其中，第一时序中驱动显示的第一像素与第二时序中驱动显示的第二像素复用至少一个像素岛中的子像素，该第二像素与第三时序中驱动显示的第三像素复用至少一个像素岛中的子像素，且该第一像素、第二像素和第三像素沿平行于栅线的方向排列。
该第四时序中驱动显示的第四像素与第五时序中驱动显示的第五像素复用至少一个像素岛中的子像素，该第五像素与第六时序中驱动显示的第六像素复用至少一个像素岛中的子像素，且该第四像素、第五像素和第六像素沿平行于栅线的方向排列。
上述第一像素还与第四像素复用至少一个像素岛中的子像素，且该第一像素和第四像素沿平行于数据线的方向排列；上述第二像素还与第五像素复用至少一个像素岛中的子像素，且第二像素与第五像素沿平行于数据线的方向排列；上述第三像素还与第六像素复用至少一个像素岛中的子像素，且第三像素与第六像素沿平行于数据线的方向排列。
例如，参考图8，时序1中的第一个第一像素和时序2中的第一个第二像素共用了R和B子像素。该时序2中第一个第二像素还和时序3中第一个第三像素共用了B和G子像素。时序1中的第一个第一像素和时序4中的第一个第四像素共用了B和G子像素。该时序2中第一个第二像素和时序5中第一个第五像素共用了R子像素。该时序3中第一个第三像素和时序6中第一个第六像素共用了R和B子像素。上述第一像素、第二像素和第三像素均沿长度方向X排列，第四像素、第五像素和第六像素也均沿长度方向X排列。并且，上述第一像素和第五像素沿宽度方向Y排列，第二像素和第四像素沿宽度方向Y排列，第三像素和第六像素也沿宽度方向Y排列。
本公开实施例中所提出的基于所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，可以采用高刷新率的显示面板10，通过沿长度方向X排列的像素时分复用相邻子像素，以及沿宽度方向Y排列的像素时分复用相邻子像素的方法，进行长度方向X和宽度方向Y的3D显示分辨率的提升。
本公开实施例提供的显示方法，在时序1、时序2、时序3、时序4、时序5和时序6时复用了R、G、B子像素，控制单元控制渲染单元分别在不同时序进行相应的3D图像的渲染，这样复用后在最终的长度方向X和宽度方向Y上，相邻两个彩色融合像素的间距为都为4个子像素。相比未复用的情况，长度方向的分辨率提升了3倍，宽度方向的分辨率提升了2倍。由于此时在一个显示周期包含6个时序，此时要求显示面板10具有至少180Hz的刷新率，以保证每个时序的刷新率不小于30Hz，在观看时不发生图像的闪烁。
根据本公开实施例的第三方面，提供显示装置的另一种显示方法，所述显示方法用于如上所述的显示装置，所述显示方法包括：
在每个显示周期内，逐行驱动所述显示装置包括的多行像素进行显示。
其中，每个像素包括：彼此相邻的所述第一像素岛、所述第二像素岛和所述第三像素岛，且么给所述像素岛中的各个子像素的灰阶均相同。
也就是说，本实施例中所提出的基于所述重复单元中所述第一像素岛、所述第二像素岛和所述第三像素岛彼此相邻的排列方式，在不采用2D/3D切换元件(如液晶透镜和双折射透镜)，通过控制单元控制渲染单元使得重复单元中的第一像素岛、第二像素岛和所述第三像素岛中的子像素显示相同的灰阶，而 使第一像素岛、第二像素岛和所述第三像素岛共同构成一个彩色的像素，使得整个显示装置显示2D图像。
更进一步，在本公开的另一2D图像显示方法中，采用时分复用方式复用所述像素岛进行显示，以进一步提升2D图像显示的分辨率，减轻了使用微透镜阵列的3D显示对2D显示的分辨率劣化问题。在普通基于微透镜阵列的3D显示中，由于2D图像的像素大小受到微透镜尺寸的影响，2D显示分辨率会劣化。
可选地，每个显示周期中可以包括多个时序，该多个时序中任意两个时序驱动显示的像素不同，且任意两个时序驱动显示的像素复用至少一个所述像素岛。
具体地，在同一显示周期中包括2m、或者3m、或者6m个时序，其中m为大于等于1的正整数；每一时序的图像刷新频率大于F，F为人眼不能感知到图像的闪烁时的刷新频率。如图9所示，时序1至时序6复用了R、G和B像素岛，其原理如上所述，在此不在累述。在相邻的时序的图像中，空间相邻的两个像素采用第一像素岛11、第二像素岛12和第三像素岛13中的部分像素岛共用，从而实现时分复用，并提高分辨率。例如图9中，时序1中的第一个像素与时序2中的第一个像素共用了第一像素岛11和第三像素岛13，且与时序4中的第一个像素共用了第二像素岛12和第三像素岛13。时序2中的第一个像素还与时序3中的第一个像素共用了第二像素岛12和第三像素岛13，且还与时序5中的第一个像素共用了第三像素岛13。
控制单元控制渲染单元分别在不同时序进行相应的3D图像的渲染，使得2D显示图像的分辨率得到了提升。
由于此时在一个显示周期包含6个时序，因此要求显示面板10具有至少180Hz的刷新率，以保证每个时序的刷新率不小于30Hz，在观看时不发生图像的闪烁。
应当理解的是，本公开实施例所述的基于所述重复单元中所述第一像素岛11、所述第二像素岛12和所述第三像素岛13彼此相邻的排列方式，减小了微透镜的尺寸，因此即使不采用时分复用的方式，2D图像的显示分辨率劣化问题也得到了改善。
以上所述仅为本公开的示例性实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本 公开保护的范围之内。
