具体地，多个所述驱动薄膜晶体管T1包括多个沿第一方向F1依次排列的驱动薄膜晶体管组103G，各所述驱动薄膜晶体管组103G与所述旋转轴20之间的距离在一预设距离S范围内，一所述驱动薄膜晶体管组103G包括至少两所述驱动薄膜晶体管T1，所述第一方向F1与所述旋转轴20垂直，且所述第一方向F1由所述旋转轴20向所述显示面板10远离所述旋转轴20的一侧边延伸；
其中，预设距离S范围内为亮度调整范围，预设距离S范围外为各驱动薄膜晶体管T1的驱动电流值达到正常工作状态下的最大值，各个驱动薄膜晶体管T1的驱动电流大小相等；
具体地，在控制电路中，所述驱动薄膜晶体管T1控制所述第一发光器件102a1的亮度大小，且在显示面板10显示时，经过所述驱动薄膜晶体管T1的驱动电流越大，所述第一发光器件102a1的亮度越大，即所述第一发光器件102a1发光时，所述第一发光器件102a1的亮度与流经所述驱动薄膜晶体管T1的驱动电流的大小呈正相关。
具体地，流经所述驱动薄膜晶体管T1的驱动电流大小的控制方法包括但不限于通过显示面板10的驱动芯片预先设置，或通过在控制电路上串联不同阻值的电阻实现不同行或列上流经所述驱动薄膜晶体管T1的驱动电流大小的 调控。
可以理解的是，通过设置显示面板10绕一旋转轴20转动，显示面板10包括多个间隔设置的驱动薄膜晶体管T1和多个间隔设置的第一发光器件102a1，一所述驱动薄膜晶体管T1连接一所述第一发光器件102a1；
多个所述驱动薄膜晶体管T1包括多个沿第一方向F1依次排列的驱动薄膜晶体管组103G，各所述驱动薄膜晶体管组103G与所述旋转轴20之间的距离在一预设距离S范围内，一所述驱动薄膜晶体管组103G包括至少两所述驱动薄膜晶体管T1，驱动薄膜晶体管T1控制所述第一发光器件102a1发光时，在第一方向F1上，其中一靠近旋转轴20的驱动薄膜晶体管组103G内各驱动薄膜晶体管T1的驱动电流小于另一远离旋转轴20的驱动薄膜晶体管组103G内各驱动薄膜晶体管T1的驱动电流，由于驱动薄膜晶体管T1控制第一发光器件102a1发光，且第一发光器件102a1的亮度与所述驱动薄膜晶体管T1中驱动电流的大小呈正相关，驱动薄膜晶体管T1中的驱动电流越大，第一发光器件102a1的亮度越大，因此设置靠近旋转轴20的所述驱动薄膜晶体管组103G内驱动薄膜晶体管T1的驱动电流小于另一远离旋转轴20的驱动薄膜晶体管组103G内驱动薄膜晶体管T1的驱动电流，能够解决三维立体显示装置中，显示面板10上不同位置的第一发光器件102a1因转动线速度不同导致的亮度不均的问题，进一步提升三维立体显示装置的显示亮度均一性。
在一实施例中，一所述驱动薄膜晶体管组103G包括至少一驱动薄膜晶体管子组1031，一所述驱动薄膜晶体管子组1031包括至少两所述驱动薄膜晶体管T1，所述驱动薄膜晶体管子组1031内至少两所述驱动薄膜晶体管T1沿第二方向F2间隔均匀排列，所述第二方向F2与所述旋转轴20平行；
在所述驱动薄膜晶体管T1控制所述第一发光器件102a1发光时，至少一所述驱动薄膜晶体管组103G内，各所述驱动薄膜晶体管子组1031中各所述驱动薄膜晶体管T1驱动电流大小相等。
具体地，一所述驱动薄膜晶体管组103G内各所述驱动薄膜晶体管子组1031内的驱动薄膜晶体管T1驱动电流大小相等，但是并不限制所有的驱动薄膜晶体管组103G内的各所述驱动薄膜晶体管子组1031内驱动薄膜晶体管T1驱动电流大小相等，使得多个驱动薄膜晶体管组103G的多个驱动薄膜晶体管 T1的驱动电流大小在第一方向F1上整体呈现递增的趋势，即部分位置的驱动薄膜晶体管T1的驱动电流大小可以相等，使得显示面板10的亮度调整灵活性更高，不影响显示装置显示的亮度均一性。
具体地，同一驱动薄膜晶体管子组1031内，在第二方向F2上，多个驱动薄膜晶体管T1的驱动电流可以相等，也可以不等，具体可以根据显示装置的显示面板10形状，或旋转轴20实际的旋转情况进行调整，以使显示装置的显示亮度均一性更高。
可以理解的是，通过设置至少一所述驱动薄膜晶体管组103G内的各所述驱动薄膜晶体管子组1031中所述第一发光器件102a1的分布密度相同，使得显示装置的显示面板10的亮度调整灵活性更高，不影响显示装置显示的亮度均一性。
承上述实施例，如图2和图3所示，所述显示面板10包括驱动器件层M20，所述驱动器件层M20包括有源层，所述驱动薄膜晶体管T1包括位于所述有源层上的沟道部T101；
在所述第一方向F1上，其中一靠近所述旋转轴20的所述驱动薄膜晶体管组103G内所述驱动薄膜晶体管T1的沟道部T101的宽长比小于另一远离所述旋转轴20的所述驱动薄膜晶体管组103G内所述驱动薄膜晶体管T1的沟道部T101的宽长比。
具体地，所述驱动薄膜晶体管T1中，沟道部T101宽长比减小，相应驱动薄膜晶体管T1的开态电流会降低。
具体地，所述沟道部T101的宽如图3中的W所示，为源极T104与漏极T103之间相对部分的长度；所述沟道部T101的长如图3中L所示，即源极T104与漏极T103之间的间距。
可以理解的是，通过调整驱动薄膜晶体管T1中沟道部T101的宽长比，实现对驱动薄膜晶体管T1的开态电流的大小的控制，进而实现对第一发光器件102a1的亮度的调整，采用该技术方案，极大的简化了显示装置显示方法的复杂性，且普适性高，不需要额外改变旋转装置的物理结构。
在一实施例中，所述显示面板10包括基板M201和设置于所述基板M201上的薄膜晶体管层M202，所述基板M201的材料为透明材料。
具体地，所述基板M201的材质可以为透明玻璃，聚酰亚胺等。
具体地，所述薄膜晶体管层M202包括多个驱动薄膜晶体管T1，所述薄膜晶体管层M202包括层叠设置的多层绝缘层，设置于各所述绝缘层之间的有源层、栅极层、源漏极T103层，其中所述有源层包括沟道部T101，设置于所述沟道部T101两侧的源极T104连接部和漏极T103连接部，其中源极T104连接部与所述源极T104连接，所述漏极T103连接部与所述漏极T103连接，所述栅极层上的栅极T102可以设置于所述沟道部T101的上方或下方(图2为下方)，且其在垂直所述驱动器件层M20的方向上的投影覆盖所述沟道部T101。
可以理解的是，通过设置所述薄膜晶体管层M202的基板M201的材料为透明材料，使得显示装置具有更高的透明度，使得三维显示装置显示的画面更逼真，提升用户的使用体验。
在一实施例中，如图5、图6、图7和图8所示，显示面板10包括发光层，发光层包括多个沿所述第一方向F1依次排列的第一发光器件组101a1，各所述第一发光器件组101a1与所述旋转轴20之间的距离在所述预设距离S范围内，一所述第一发光器件组101a1包括至少两所述第一发光器件102a1；
在所述第一方向F1上，一靠近所述旋转轴20的所述第一发光器件组101a1内各所述第一发光器件102a1的分布密度小于另一远离所述旋转轴20的所述第一发光器件组101a1内各所述第一发光器件102a1的分布密度。
具体地，多个所述第一发光器件组101a1之间的间距可以相同，也可以不同，具体不作限制，但是多个第一发光器件组101a1之间的间距不同不能影响显示装置发光的均一性，图7和图8均为多个所述第一发光器件组101a1之间的间距相同的情形；
具体地，一所述第一发光器件组101a1包括至少两所述第一发光器件102a1，多个第一发光器件组101a1在第二方向F2(与旋转轴20平行)上的长度不变。
具体地，当所述第一发光器件组101a1中包括多个间隔设置的第一发光器 件102a1时，该第一发光器件组101a1内的第一发光器件102a1的分布密度也可以在所述第一方向F1上逐渐增加(如图9所示)，或该第一发光器件组101a1内的多个第一发光器件102a1均匀分布。
具体地，所述分布密度是指相同的单位面积内，所述第一发光器件102a1的数量，其中单位面积的长度可以与显示面板10与旋转轴20平行的一侧边的长度相同，单位面板的宽度至少大于一个第一发光器件102a1的宽度。
具体地，在一实例中，假设初始第一发光器件102a1的排布设置为m行n列，每旋转α度显示面板10刷新一次，则满足:
第t列的第一发光器件102a1的数量
且第一发光器件102a1在该列上均匀分布，其中t取大于1，且小于或等于n的正整数；
采用上述技术方案能够使得显示面板10上第一发光器件102a1的使用处于最高效率的状态。
可以理解的是，通过设置显示面板10包括多个间隔设置的第一发光器件102a1，第一发光器件102a1与驱动薄膜晶体管T1为一一对应的关系，多个第一发光器件102a1包括多个第一发光器件组101a1，各第一发光器件组101a1与旋转轴20之间的距离在一预设距离S范围内，一第一发光器件组101a1包括至少两第一发光器件102a1，多个第一发光器件组101a1沿第一方向F1依次排列，在第一方向F1上，一靠近旋转轴20的第一发光器件组101a1内第一发光器件102a1的分布密度小于另一远离旋转轴20的第一发光器件组101a1内第一发光器件102a1的分布密度，通过降低靠近旋转轴20的第一发光器件102a1的分度密度，使得显示装置在进行三维显示时，在预设的范围内靠近旋转轴20的第一发光器件102a1的亮度能够与预设范围外的第一发光器件102a1的亮度相一致，配合调整对应的驱动薄膜晶体管T1中驱动电流大小的技术方案，一方面能够解决三维立体显示装置中，显示面板10上不同位置的第一发光器件102a1因转动线速度不同导致的显示装置整体上亮度不均的问题，进一步提升三维立体显示装置的显示亮度均一性，另一方面，通过两种技术方案综合使用，使得其能够解决单一调整第一发光器件102a1分布密度导致的靠近旋 转轴20的第一发光器件102a1之间的间距过大，亮度分布不均，影响显示装置显示的PPI，影响显示效果的问题。
在一实施例中，如图7和图8所示，一所述第一发光器件组101a1包括至少一第一子组1011，一所述第一子组1011包括至少两所述第一发光器件102a1，所述第一子组1011内至少两所述第一发光器件102a1沿第二方向F2依次排列，所述第二方向F2与所述旋转轴20平行，至少一所述第一发光器件组101a1内的各所述第一子组1011中所述第一发光器件102a1的分布密度相同。
具体地，多个所述第一发光器件组101a1则包括多个第一子组1011，多个第一子组1011可以均沿所述第一方向F1依次排列，一第一子组1011内的第一发光器件102a1沿第二方向F2依次排列。
具体地，一所述第一发光器件组101a1内各所述第一子组1011内的第一发光器件102a1的分布密度相同，但是并不限制所有的第一发光器件组101a1内的各所述第一子组1011的第一发光器件102a1的分布密度相同，使得多个发光单元组的多个发光单元在整体上呈现分布密度递增的趋势即可，具体地如图6和图7所示，部分位置的第一发光器件102a1的分布密度可以相等，使得显示面板10的亮度调整灵活性更高，不影响显示装置显示的亮度均一性。
具体地，同一第一子组1011内，多个第一发光器件102a1可以间隔均匀设置，也可以具有多个间隔距离，具体可以根据显示装置的显示面板10形状，或旋转轴20实际的旋转情况进行调整，以使显示装置的显示亮度均一性更高。
可以理解的是，通过设置至少一所述第一发光器件组101a1内的各所述第一子组1011中所述第一发光器件102a1的分布密度相同，使得显示装置的显示面板10的亮度调整灵活性更高，不影响显示装置显示的亮度均一性。
在一实施例中，一所述第一发光器件组101a1包括至少两沿所述第一方向F1排列的所述第一子组1011，所述第一子组1011包括多个所述第一发光器件102a1，且多个所述第一发光器件102a1沿所述第二方向F2间隔均匀设置。
需要说明的是，由于显示面板10是绕旋转轴20旋转，显示面板10旋转对应产生亮线的原因是由于在第一方向F1上不同第一发光器件102a1的旋转 线速度不同，但是在第二方向F2上，各第一发光器件102a1的旋转线速度是相同的。
可以理解的是，设置所述第一子组1011中的第一发光器件102a1在所述第二方向F2上间隔均匀设置，能够使得显示面板10在第二方向F2上的显示亮度更均匀，提升显示装置的显示亮度均一性。
在一实施例中，任意相邻的两所述第一子组1011内，其中一所述第一子组1011中的所述第一发光器件102a1与另一所述第一子组1011中的所述第一发光器件102a1沿所述第二方向F2交错设置。
具体地，在本实施例中，所述交错设置是指，在第一方向F1上，相邻的两所述第一子组1011分别为第一子组1011和第二第一子组1011，第一子组1011中的第一发光器件102a1与所述第二第一子组1011中的第一发光器件102a1不同行设置。
可以理解的是，设置任意相邻的两所述第一子组1011内，其中一所述第一子组1011中的所述第一发光器件102a1与另一所述第一子组1011中的所述第一发光器件102a1沿所述第二方向F2交错设置，能够有效防止显示装置显示过程中，部分位置因为第一发光器件102a1集中导致产生横向亮线的问题，进一步提升显示装置的显示均匀程度。
在一实施例中，一所述第一发光器件组101a1包括至少两所述第一子组1011，任意两所述第一发光器件组101a1中，其中一所述第一发光器件组101a1内的各所述第一子组1011之间的间距与另一所述第一发光器件组101a1内的各所述第一子组1011之间的间距相等。
具体地，其中一所述第一发光器件组101a1内的各所述第一子组1011之间的间距与另一所述第一发光器件组101a1内的各所述第一子组1011之间的间距相等可以理解为，在第一方向F1上，即使任一第一发光器件组101a1中，各第一子组1011的排布是均匀的。
可以理解的是，通过设置一所述第一发光器件组101a1内的各所述第一子组1011之间的间距与另一所述第一发光器件组101a1内的各所述第一子组 1011之间的间距相等，能够使得显示面板10在第一方向F1上的亮度更均匀，同时方便显示面板10的生产。
在一实施例中，如图10所示，所述旋转轴20将所述显示面板10划分为第一显示部10A1和第二显示部10A2，所述第一显示部10A1包括多个所述第一发光器件102a1，所述第二显示部10A2包括多个第二发光器件组101a2，多个所述第二发光器件组101a2沿第一方向F1排列，所述第二器件组包括多个第二发光器件102a2；
其中，在距离所述旋转轴20的长度相同的所述第一发光器件组101a1和所述第二发光器件组101a2中，所述第一发光器件组101a1上的多个所述第一发光器件102a1和所述第二发光器件组101a2上的多个所述第二发光器件102a2沿所述第二方向F2交错设置。
需要说明的是，当旋转轴20上有两块或以上的显示面板10(或两个及以上的显示部)绕旋转轴20旋转时，本实施例以两显示部为例进行说明，当个两显示部上的部分发光器件102关于旋转轴20对称时，显示装置显示时，对应对称的部分使得对应位置亮度重合，产生亮点或亮线，影响三维显示的显示效果，为了避免上述技术问题，提供本实施例的技术方案。
具体地，在本实施例中，所述显示面板10可以为一整块显示面板10，也可以为拼接的显示面板10，若为拼接的显示面板10时，拼接缝与所述旋转轴20重合。
具体地，在本实施例中，所述第一显示部10A1和所述第二显示部10A2的面积大小可以相同，也可以不同，本实施例以所述第一显示部10A1和所述第二显示部10A2的面积大小相同为例进行说明。
具体地，由于第一显示部10A1和第二显示部10A2对称设置(形状对称)，但是第一显示部10A1上的第一发光器件102a1和所述第二显示部10A2上的第二发光器件102a2并不对称设置。
具体地，所述第一显示部10A1上的第一发光器件102a1的变化率(多个第一发光器件102a1的分布密度相对距离所述旋转轴20的距离的变化率)与所述第二显示部10A2上的第二发光器件102a2的变化率(多个第二发光器件 102a2的分布密度相对距离所述旋转轴20的距离的变化率)相同。
具体地，在第一方向F1上，距离所述旋转轴20长度相同的第一发光器件组101a1和第二发光器件组101a2，第一发光器件组101a1中的第一发光器件102a1与所述第二发光器件组101a2中的第二发光器件102a2不同行设置。
换而言之，即在本实施例中，第一显示部10A1绕所述旋转轴20旋转后与所述第二显示部10A2重叠，但是第一显示部10A1上的第一发光器件102a1与所述第二显示部10A2上的第二发光器件102a2不重叠。
或者，所述第一发光器件组101a1上的多个所述第一发光器件102a1和所述第二发光器件组101a2上的多个所述第二发光器件102a2的转动路径不重叠。
具体地，当三块显示面板10绕所述旋转轴20旋转，且三块显示面板10相对关于所述旋转轴20轴对称时，三块显示面板10绕旋转轴20旋转重叠后，三块显示面板10上的发光器件102各不重叠。
可以理解的是，通过采用上述技术方案，能够使得显示装置的显示效果更均匀，且设置多块显示面板10也不会在显示装置进行三维显示时产生亮线或者亮点，提升显示装置的显示效果，延长显示装置的使用寿命。
承上述实施例，所述第一显示部10A1远离所述旋转轴20的一侧边至所述旋转轴20的距离与所述第二显示部10A2远离所述旋转轴20的一侧边至所述旋转轴20的距离相等。
具体地，在本实施例中，即所述第一显示部10A1的面积和所述第二显示部10A2的面积相等，且所述第一显示部10A1的形状与所述第二显示部10A2的形状相等，所述第一显示部10A1上的第一发光器件102a1的变化率(多个第一发光器件102a1的分布密度相对距离所述旋转轴20的距离的变化率)与所述第二显示部10A2上的第二发光器件102a2的变化率相同，所述第一显示部10A1上不同之处在于所述第一显示部10A1上第一发光器件102a1的排布位置与所述第二显示部10A2上的发光器件102的排布位置不同。
综上，通过设置显示面板10绕一旋转轴20转动显示，显示面板10包括层叠设置的发光层和驱动器件层，所述发光层包括多个间隔设置的第一发光器件102a1，所述驱动器件层包括多个沿第一方向F1依次排列的驱动薄膜晶体 管组103G，一所述驱动薄膜晶体管组103G包括至少两所述驱动薄膜晶体管T1，所述第一发光器件102a1发光时，在第一方向F1上，其中一靠近旋转轴20的驱动薄膜晶体管组103G内各驱动薄膜晶体管T1的驱动电流小于另一远离旋转轴20的驱动薄膜晶体管组103G内各驱动薄膜晶体管T1的驱动电流，由于驱动薄膜晶体管T1控制发光器件102发光，且第一发光器件102a1的亮度与所述驱动薄膜晶体管T1中驱动电流的大小呈正相关，驱动薄膜晶体管T1中的驱动电流越大，第一发光器件102a1的亮度越大，因此设置靠近旋转轴20的所述驱动薄膜晶体管组103G内驱动薄膜晶体管T1的驱动电流小于另一远离旋转轴20的驱动薄膜晶体管组103G内驱动薄膜晶体管T1的驱动电流，能够解决三维立体显示装置中，显示面板10上不同位置的第一发光器件102a1因转动线速度不同导致的亮度不均的问题，进一步提升三维立体显示装置的显示亮度均一性。
