参考图2和图3，图2为本发明的显示装置的第一实施例的结构示意图，图3为图2中的显示装置的像素单元211的结构示意图。
本实施例的显示装置包括显示面板21和透镜板22。所述透镜板22与所述显示面板21叠加组合为一体，具体地，所述透镜板22设置于所述彩色滤光片基板背向所述液晶层的一面上。所述显示面板21包括薄膜晶体管阵列基板212、彩色滤光片基板和液晶层，所述薄膜晶体管阵列基板212和所述彩色滤光片基板平行设置，所述液晶层设置于所述薄膜晶体管阵列基板212和所述彩色滤光片基板之间。

在本实施例中，所述透镜板22包括透镜阵列，所述透镜阵列包括至少两条状透镜221，至少两所述条状透镜221并列设置，并且至少两所述条状透镜221沿第一方向排列，其中，所述第一方向为垂直于所述条状透镜221所在的直线的方向，所述条状透镜221所在的直线与所述第一像素部2111和所述第二像素部2112的连线具有一夹角，所述夹角处于10度至80度的范围内，例如，所述夹角为10度、14度、17度、19度、21度、23度、26度、29度、31度、34度、36度、38度、40度、43度、45度、47度、50度、52度、55度、57度、59度、62度、66度、67度、69度、71度、73度、76度、78度、80度等。任意相邻两所述条状透镜221之间的间距相等。所述透镜阵列在所述第一方向上的结构周期性相似。
在本实施例中，所述片状电极21121包括一第一区块电极，所述第一区块电极的面积与所述第二像素部2112的面积的比值处于0.6至0.98的范围内，例如，所述比值为0.6、0.62、0.65、0.66、0.68、0.70、0.73、0.76、0.77、0.79、0.82、0.84、0.85、0.87、0.89、0.91、0.94、0.96、0.97、0.98等。
在本实施例中，所述显示装置还包括控制器，所述控制器用于切换所述显示装置的显示模式，其中，所述显示模式包括二维图像显示模式和三维图像显示模式，即，所述控制器用于将所述显示装置从二维图像显示模式切换三维图像显示模式，以及用于将所述显示装置从所述三维图像显示模式切换为所述二维图像显示模式。
在所述显示装置从所述二维图像显示模式切换到所述三维图像显示模式时，所述控制器用于通过所述第一扫描线向所述第一开关发送第一扫描信号，以关闭所述第一开关，以及用于通过所述第二扫描线向所述第二开关发送第二扫描信号，以开启所述第二开关。在本实施例中，所述第一开关用于在所述显示装置处于三维图像显示模式时关闭所述第一电流通道，以阻止所述三维图像数据输入到所述条状电极21111中。所述第二开关用于在所述显示装置处于所述三维图像显示模式时开启所述第二电流通道，以使所述三维图像数据输入到所述片状电极21121中。
在所述显示装置从所述三维图像显示模式切换到所述二维图像显示模式时，所述控制器用于通过所述第一扫描线向所述第一开关发送所述第一扫描信号，以开启所述第一开关，以及用于所述第二扫描线向所述第二开关发送所述第二扫描信号，以关闭所述第二开关。在本实施例中，所述第一开关用于在所述显示装置处于二维图像显示模式时开启所述第一电流通道，以使二维图像数据输入到所述条状电极21111中。所述第二开关用于在所述显示装置处于所述二维图像显示模式时关闭所述第二电流通道，以阻止所述二维图像数据输入到所述片状电极21121中。
由于所述透镜板22中的至少两所述条状透镜221沿所述第一方向排列，所述第一方向垂直于所述条状透镜221所在的直线，所述条状透镜221所在的直线与所述第一像素部2111和所述第二像素部2112之间的连线具有所述夹角，所述夹角处于10度至80度的范围内，并且由于所述间隔条阵列的排列方向平行于或垂直于所述第一像素部2111和所述第二像素部2112之间的连线，因此，当所述显示装置处于所述三维图像显示模式时，光线透过所述显示面板21和所述透镜板22后不会产生光学干涉现象，避免了摩尔纹现象的产生，提高了所述显示装置的显示质量。
此外，在所述第二像素部2112中设置所述片状电极21121是为了避免条状的电极所在的直线与所述条状透镜221所在的直线平行，从而避免产生光学干涉现象，原因是所述第二像素部2112中不存在亮暗条纹，因此不会与所述透镜阵列发生光学干涉。另外，在所述显示装置处于所述三维图像显示模式时，相对于所述间隔条倾斜的所述条状透镜221避免了因条状的电极而产生的摩尔纹现象，提高了所述显示装置的显示质量。
本发明的显示装置的第二实施例与上述第一实施例相似，不同之处在于：
所述片状电极21121包括至少两第二区块电极，相邻两所述第二区块电极相连，至少两所述第二区块电极以阵列的形式排列。至少两所述第二区块电极拼接成所述片状电极21121。所述第二区块电极的形状可以是菱形、三角形、矩形、平行四边形、梯形、圆形、六边形等。
由于所述片状电极21121由至少两所述第二区块电极拼接而成，因此所述第二像素部2112中不存在亮暗条纹，避免了条状的电极所对应的阵列与所述透镜阵列发生光学干涉，从而避免了摩尔纹现象，提高了所述显示装置的显示质量。
本发明的显示装置显示图像的方法实施于上述显示装置中，所述方法包括以下步骤：
步骤41，所述第一扫描线向所述第一开关发送第一扫描信号，以控制所述条状电极21111与数据线之间的第一电流通道的开启或关闭，所述第二扫描线向所述第二开关发送第二扫描信号，以控制所述片状电极21121与所述数据线之间的第二电流通道的开启或关闭。具体地，在所述显示装置处于二维图像显示模式时，所述第一扫描信号用于开启所述第一开关，所述第二扫描信号用于关闭所述第二开关；相对应地，在所述显示装置处于三维图像显示模式时，所述第一扫描信号用于关闭所述第一开关，所述第二扫描信号用于开启所述第二开关。
步骤42，所述第一开关在所述显示装置处于所述二维图像显示模式时开启所述第一电流通道，以使二维图像数据输入到所述条状电极21111中。
