传统的显示装置为了解决大视角色偏的技术问题,一般会采用LCS(Low Color Shift,低色偏)技术,具体地,将像素单元中的子像素单元100分为主分区(Main)101和副分区(Sub)102,如图1所示,该主分区101和副分区102分别使用不同电压来驱动,以产生不同的亮度,使得混色后的像素单元的亮度在不同视角观看时偏差不会太大。
在实践中,发明人发现现有技术至少存在以下问题:
当副分区102处于不同极性切换的状态时,副分区102的电压变化较大,亮度下降明显;当副分区102处于相同极性切换的状态时,副分区102的电压变化较小,亮度下降不明显。因此,副分区102在相邻两帧(Frame)之间存在极性切换时会表现出不同的亮度。
而当上述显示装置处于三维显示模式时,左右帧中的一帧会永远处于相同极性切换的状态,另一帧则会永远处于不同极性切换的状态,这样会使得观看者左右眼所看到的副分区102的亮度会永远不同,从而造成观看者的眼睛不适。
故,有必要提出一种新的技术方案,以解决上述技术问题。

在本实施例中,所述第一控制信号为通过所述第二扫描线203发送的栅极开关信号(扫描信号)。
参考图3,图3为本发明的显示装置中子像素单元的第二实施例的电路示意图。本实施例与上述实施例相似,不同之处在于:
在本实施例中,所述开关单元还包括一第四薄膜晶体管301。其中,所述第四薄膜晶体管301用于接收第二控制信号和所述第一控制信号,并根据所述第二控制信号向所述第三薄膜晶体管209的所述第三栅极提供所述第一控制信号。
所述第四薄膜晶体管301包括一第四漏极、一第四源极和一第四栅极。
其中,所述第四栅极用于接收所述第二控制信号,以控制所述第四漏极和所述第四源极之间的第二电流通道打开或关闭。所述第三薄膜晶体管209的所述第三栅极与所述第四漏极、所述第四源极中的一者连接,所述第四漏极、所述第四源极中的另一者与所述显示面板的第二扫描线203连接。

在本实施例中,所述第二控制信号是三维显示使能信号经过金属氧化物半导体管403反向后得到的。如图4所示,附图标记401、402、403、404、405分别表示三维显示使能信号输入端、第二控制信号输出端、金属氧化物半导体管、电源端、接地端。其中,三维显示使能信号输入端401用于输入三维显示使能信号(3D_EN),第二控制信号输出端402用于输出第二控制信号。
在本实施例中,通过利用所述第四薄膜晶体管301来单独地对所述第三薄膜晶体管209进行控制,有利于在所述显示装置处于三维显示模式时关闭所述第三薄膜晶体管209,阻止所述电容208从所述第二分区像素部205中接收电荷,这样即可避免所述第二分区像素部205和所述第一分区像素部204之间出现电压差,从而不会使得所述第二分区像素部205和所述第一分区像素部204的亮度有差别,即,避免了所述电容208对所述第二分区像素部205的亮度的造成影响。
在本实施例中,所述像素单元还包括共享线(Sharing Line)210,所述共享线210用于提供给所述像素单元中的三个子像素单元(红、绿、蓝)共同使用。

在所述显示装置处于三维显示模式时,所述三维显示使能信号是高电平,经过反向后得到的所述第二控制信号则为低电平,此时所述第四薄膜晶体管301的开关关闭(第二电流通道关闭),所述第二扫描线203的扫描信号无法输入到所述第三薄膜晶体管209的所述第三栅极中,因此,所述第三薄膜晶体管209无法打开所述第一电流通道,所述第二分区像素部205中的电荷无法流动到所述电容208中,此时所述第一分区像素部204和所述第二分区像素部205之间保持相同的电压,所述第一分区像素部204和所述第二分区像素部205便会产生相同的亮度,从而可以保证所述显示装置的左右眼图像亮度相同。

在本实施例中,通过利用所述第四薄膜晶体管301来单独地对所述第三薄膜晶体管209进行控制,有利于在所述显示装置处于三维显示模式时关闭所述第三薄膜晶体管209,阻止所述电容208从所述第二分区像素部205中接收电荷,这样即可避免所述第二分区像素部205和所述第一分区像素部204之间出现电压差,从而不会使得所述第二分区像素部205和所述第一分区像素部204的亮度有差别,即,避免了所述电容208对所述第二分区像素部205的亮度的造成影响。
结合图4,举例说明如下:
所述三维显示使能信号(3D_EN)通过所述金属氧化物半导体管403反向后,从所述第二控制信号输出端402输出,并从所述第四薄膜晶体管301的输入端302输入到所述第四栅极,以驱动所述第四薄膜晶体管301,进而在所述显示装置处于三维显示模式时控制所述第三薄膜晶体管209不因所述第二扫描线203的扫描信号而打开。具体地,在所述显示装置处于二维显示模式时,所述三维显示使能信号是低电平,经过反向后得到的所述第二控制信号则为高电平,此时所述第四薄膜晶体管301的开关(第二电流通道)打开,所述第二扫描线203的扫描信号便可以输入到所述第三薄膜晶体管209中,从而打开所述第三薄膜晶体管209的开关(第一电流通道),所述第二分区像素部205中的电荷输入到所述电容208中,此时所述第一分区像素部204和所述第二分区像素部205之间便会出现电压差,所述第一分区像素部204和所述第二分区像素部205便会产生不同的亮度,从而可以解决所述显示装置在处于二维显示模式时的大视角色偏问题。
