下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为解决现有技术中视角模式单一，液晶显示装置显示的便利性低的技术问题，特提出了一种液晶显示装置的视角模式切换方法和液晶显示装置，可以实现不同视角模式间的切换，提高液晶显示装置显示的便利性，该方法的实现可依赖于计算机程序，该计算机程序可运行于基于冯诺依曼体系的计算机系统之上。
为了更好地理解本发明实施例公开的一种液晶显示装置的视角模式切换方法，下面先对本发明实施例使用的液晶显示装置的像素结构示意图进行描述。请参阅图1，图1为本发明实施例公开的一种液晶显示装置的像素结构示意图。如图1所示，该像素结构示意图可以包括子像素10、第一扫描线11、与第一扫描线11相邻的第二扫描线12和第一数据线13。其中，子像素10可以包括主像素单元101、次像素单元102和共享放电单元103；进一步地，主像素单元101可以包括主薄膜晶体管1011、主像素电容1012和主存储电容1013，类似的，从像素单元102可以包括从薄膜晶体管1021、从像素电容1022和从存储电容1023，共享放电单元103可以包括共享薄膜晶体管1031和共享电容1032。主像素单元101和次像素单元102，配置为接收第一扫描线11的第一扫描信号，进而接收第一数据线13的第一数据信号，所述共享放电单元103，配置为接收与所述第一扫描线11相邻的第二扫描线12的第二扫描信号。其中，液晶显示装置可以包含多条扫描线、多条数据线和多个子像素。
基于图1所示的像素结构，请参阅图2，图2为本发明实施例公开的一种液晶显示装置的视角模式切换方法的流程示意图，其中，该液晶显示装置的视角模式切换方法是从液晶显示装置的角度来描述的，如图2所示，该液晶显示装置的视角模式切换方法可以包含以下步骤。
步骤S202：接收视角模式切换请求。
在本实施例中，所述视角模式切换请求包括目标视角模式，所述目标视角模式为第一视角模式或第二视角模式。其中，第一视角模式为大视角模式，在该模式下，视角范围得到拓宽，任意角度观看该液晶显示装置均可观看到真实、清晰的画面；第二视角模式为防窥模式，与第一视角模式相比，在该模式下，视角范围变窄，在一定的角度范围内才能够清晰的看到画面，从而可以保护观看者的隐私。其中，视角模式切换请求可以是用户通过特定的操作触发发送的，例如，在触控屏中触摸指定的功能按钮“切换为防窥模式”则触发向液晶显示装置发送模式切换请求，该请求中包含的目标视角模式为第二视角模式，即防窥模式。
步骤S204：根据所述视角模式切换请求，调整所述第二扫描信号与所述 第一扫描信号的时序关系。
在本实施例中，所述时序关系包括与所述第一视角模式对应的第一时序关系以及与所述第二视角模式对应的第二时序关系和第三时序关系。
在本实施例中，所述第一时序关系包括：所述第一扫描信号超前所述第二扫描信号，且所述第一扫描信号的有效电平与所述第二扫描信号的有效电平不重叠。
具体地，第一扫描信号的有效电平可以超前第二扫描信号的有效电平，即主薄膜晶体管和次薄膜晶体管先于共享薄膜晶体管工作，在薄膜晶体管为N型薄膜晶体管时，有效电平可以为高电平有效；在薄膜晶体管为P型薄膜晶体管时，有效电平可以为低电平有效。且第一扫描信号的有效电平期间与第二扫描信号的有效电平期间不重叠。
在本实施例中，所述主像素单元和所述次像素单元在所述第一扫描信号的有效电平期间接收所述第一数据信号而具有第一电位，所述共享放电单元在所述第二扫描信号的有效电平期间接收所述次像素单元的放电而与所述次像素单元具有相同的第二电位，所述液晶显示装置工作于所述第一视角模式。
请参阅图3，图3为本发明实施例公开的一种大视角模式的时序关系示意图，如图3所示，当第一扫描信号在有效电平期间，即第一扫描信号的电平为27V，主薄膜晶体管和次薄膜晶体管的栅极接收到该有效电平，从而处于开启状态，此时，第一数据信号也处于有效电平，如高电平14.2V，通过第一数据信号向所述主薄膜晶体管的主像素电极(包含主像素电容和主存储电容)进行充电，也对次薄膜晶体管的次像素电极(包含次像素电容和次存储电容)进行充电，一定时间后，电容充电完成，主像素电极和次像素电极电位与第一数据信号的高电平持平，为13.6V；第一扫描信号的有效电平结束后，第二扫描信号有效电平即出现，第一数据信号的有效电平结束，此时共享薄膜晶体管的栅极接收到有效电平，从而处于开启状态，次像素电极与共享电容导通而对共享电容进行充电，从而将次像素电极的电位降低于主像素电极，为9V，主像素电极的电位由于电容耦合效应略微下降，为12.5V。当主像素电极的电位和次像素电极的电位相同时，液晶显示装置对应位置的液晶倒向呈现4个方向，而由于面板的像素中，主像素电极的电位和次像素电极的电位不同，液晶显示装 置对应位置的液晶倒向呈现8个方向，液晶倒向的增多使不同视角方向液晶分子的平均折射率差异减小，起到视角补偿的作用。
在本实施例中，所述第二时序关系包括：所述第一扫描信号超前所述第二扫描信号，且所述第一扫描信号的有效电平与所述第二扫描信号的有效电平部分重叠。
具体地，第一扫描信号的有效电平可以超前第二扫描信号的有效电平，即主薄膜晶体管和次薄膜晶体管先于共享薄膜晶体管工作，且第一扫描信号的有效电平期间与第二扫描信号的有效电平期间部分重叠，即主薄膜晶体管和次薄膜晶体管开启一定时间后，主薄膜晶体管和次薄膜晶体管和共享薄膜晶体管同时开启。
在本实施例中，所述第一扫描信号与所述第二扫描信号的重叠时间大于所述第一扫描信号的有效电平持续时间的一半，并小于所述第一扫描信号的有效电平持续时间。
在本实施例中，所述主像素单元和所述次像素单元在所述第一扫描信号的有效电平期间接收所述第一数据信号而具有所述第一电位；所述共享放电单元在所述第一扫描信号和所述第二扫描信号的有效电平期间接收所述次像素单元的放电而与所述主像素单元和所述次像素单元具有相同的第一电位；所述主像素单元、所述次像素单元和所述共享放电单元在所述第一扫描信号无效且所述第二扫描信号的有效电平期间具有相同的第三电位，所述液晶显示装置工作于所述第二视角模式。
具体地，请参阅图4A，图4A为本发明实施例公开的一种防窥模式的时序关系示意图，如图4A所示，分为三个时间段描述：在t1时间段内，第一扫描信号在有效电平期间，即第一扫描信号的电平为27V，主薄膜晶体管和次薄膜晶体管的栅极接收到该有效电平，从而处于开启状态，由于第二扫描信号无效，共享薄膜晶体管处于断开状态，此时，第一数据信号也处于有效电平，如高电平14.2V，通过第一数据信号通过所述主薄膜晶体管向主像素电极(包含主像素电容和主存储电容)进行充电，也通过次薄膜晶体管向次像素电极(包含次像素电容和次存储电容)进行充电，可以经过一定时间后，电容充电完成，如主像素电极和次像素电极电位与第一数据信号的高电平持平，为13.6V并保 持不变，也可以是充电未完成状态；在t2时间段内，第一扫描信号保持有效电平，主薄膜晶体管和次薄膜晶体管保持开启，第一数据信号仍处于有效状态，同时，第二扫描信号变为有效电平，使共享薄膜晶体管处于开启状态，此时，次像素电极与共享电容连通，向共享电容充电，第一数据信号同时向主像素电极和次像素电极进行充电，使主像素电极和次像素电极与第一数据信号具有相当的电位，当t2足够长时，共享电容可以被充满，即第一扫描信号和第二扫描信号交叠时间足够长，为满足以上条件，如图4A所示，一般地，要求T2/T1在0.5～1之间；在t3时间段内，由于共享电容已被充满，即使主薄膜晶体管和次薄膜晶体管均处于断开状态，共享薄膜晶体管处于开启状态，即次像素电极和共享电容接通，次像素电容也不会像所述共享电容充电，因此主像素电极和次像素电极的电位保持相同，液晶显示装置对应位置的液晶倒向呈现4个方向，与大视角模式下，液晶倒向呈现8个方向相比，液晶倒向减少，不同视角方向液晶分子的平均折射率差异增大，即在侧面视觉效果得到抑制从而实现第二视角模式，即防窥模式。
在本实施例中，所述第三时序关系包括：所述第二扫描信号超前所述第一扫描信号，且所述第一扫描信号的有效电平与所述第二扫描信号的有效电平不重叠。
具体地，第二扫描信号的有效电平可以超前第一扫描信号的有效电平，即共享薄膜晶体管先于主薄膜晶体管和次薄膜晶体管开启，且第一扫描信号的有效电平期间与第二扫描信号的有效电平期间不重叠，即共享薄膜晶体管在有效电平内开启，主薄膜晶体管和次薄膜晶体管断开，之后共享薄膜晶体管断开，主薄膜晶体管和次薄膜晶体管开启。
在本实施例中，所述主像素单元和所述次像素单元在所述第一扫描信号的有效电平期间接收所述第一数据信号而具有第一电位，所述主像素单元和所述次像素单元在所述第一扫描信号的无效且所述第二扫描信号的无效期间具有第三电位，所述液晶显示装置工作于所述第二视角模式。
具体地，请参阅图4B，图4B为本发明实施例公开的另一种防窥模式的时序关系示意图，如图4B所示，分为两个时间段描述：在t4时间段内，第二扫描信号有效，第一扫描信号无效，也可以是第一扫描信号和第二扫描信号均无 效，且第一数据信号无效，此时，共享薄膜晶体管开启，主薄膜晶体管和次薄膜晶体管断开，主像素电极、次像素电极和共享电容均没有电量；在t5时间段内，第一扫描信号有效，第二扫描信号无效，且第一数据信号有效，主薄膜晶体管和次薄膜晶体管开启，共享薄膜晶体管断开，第一数据信号对主像素电极和次像素电极充电，共享电容与次像素电极连接断开，因此主像素电极和次像素电极的电位保持相同，液晶显示装置对应位置的液晶倒向呈现4个方向，与大视角模式下，液晶倒向呈现8个方向相比，液晶倒向减少，不同视角方向液晶分子的平均折射率差异增大，即在侧面视觉效果得到抑制从而实现第二视角模式，即防窥模式。
在本实施例中，可以通过修改所述次像素单元和所述共享放电单元间的连接，将所述液晶显示装置从所述第一视角模式切换为所述第二视角模式。
具体地，请参阅图5，图5为本发明实施例提供的一种版图设计示意图，如图5所示，在该版图中，虚线框501部分实现主像素单元，502实现次像素单元，503实现共享放电单元，504实现第一扫描线，505实现第二扫描线，506实现第一数据线。其中，主像素电极和次像素电极由示意图中“米”型区域实现，采用氧化铟(Indium tin oxide，ITO)实现，在薄膜晶体管中非晶硅为半导体层，实现晶体管的导通，若去掉该非晶硅，则薄膜晶体管断开。在图5的A中，实线框中的为共享放电单元中的共享薄膜晶体管5031，可实现图1所示的像素结构示意图，可以工作在第一视角模式，即大视角模式，可以在第一数据线的控制下，与次像素电极导通；在图5的A的基础上，可以将实线框中的共享薄膜晶体管5031的非晶硅层去掉，从而共享电容与次像素电极断开，次像素电极不会对共享电容放电，主像素电极和次像素电极电位始终保持相同，从而实现第二视角模式，即防窥模式。也可以通过修改光罩来实现共享放电单元与次像素电极的连接断开，在版图上实现第二视角模式。
步骤S206：根据所述第二扫描信号与所述第一扫描信号的时序关系的变化，指示所述液晶显示装置在第一视角模式和第二视角模式之间进行切换。
在图2所示的液晶显示装置的视角模式切换方法中，接收视角模式切换请求，视角模式切换请求包括目标视角模式，目标视角模式为第一视角模式或第二视角模式；根据视角模式切换请求，调整第二扫描信号与第一扫描信号的时 序关系，时序关系包括与第一视角模式对应的第一时序关系以及与第二视角模式对应的第二时序关系和第三时序关系；根据第二扫描信号与第一扫描信号的时序关系的变化，指示液晶显示装置在第一视角模式和第二视角模式之间进行切换，可见，根据模式切换请求，可以实现不同视角模式间的切换，提高液晶显示装置显示的便利性。
此外，为解决现有技术中视角模式单一，液晶显示装置显示的便利性低的技术问题，在一个实施例中，特提出了一种液晶显示装置，请参阅图6，图6为本发明实施例提供的一种液晶显示装置结构示意图，图6所示的液晶显示装置结构示意图可以包含图1，如图1所示，该装置包括：多条扫描线、多条数据线和多个子像素10；所述子像素包括主像素单元101、次像素单元102和共享放电单元103，所述主像素单元101和次像素单元102，配置为接收第一扫描线的第一扫描信号，进而接收第一数据线的第一数据信号而具有第一电位，所述共享放电单元103，配置为接收与所述第一扫描线相邻的第二扫描线的第二扫描信号，进而接收所述次像素单元102的放电而与所述次像素单元102具有相同的第二电位，如图6所示，所述液晶显示装置还包括：
