所述第二偏光器12101设于所述第一分析器11105远离所述第二玻璃基板11104一侧,为了保证自所述第一显示面板110出射的光线可以最大化的进入所述第二显示面板120,所述第二偏光器12101的可通过光线方向与所述第一分析器11105的可通过光线方向一致。
所述第三玻璃基板12102设于所述第二偏光器12101远离所述第一分析器11105一侧,所述第三玻璃基板12102的材质与所述第一玻璃基板11102的材质相同。
所述第二液晶单元12103设于所述第三玻璃基板12102远离所述第二偏光器12101一侧,所述第二偏光器12101的可通过光线方向与所述第二分析器12106可通过光线方向垂直,当所述第二液晶单元12103上下无电场时,所述第二液晶单元12103中的液晶分子平行于第二偏光器12101的排列方向,光线无法通过所述第二分析器12106,此时所述显示单元不显示画面。
所述色阻层12104设于所述第二液晶单元12103远离所述第三玻璃基板12102一侧,所述色阻层12104包括蓝色子像素、绿色子像素和红色子像素三种颜色,本实施例中,所述像素单元121包括横向排列的三种不同颜色的色阻层12104,由于所述像素单元121包括了三原色的组成像素,故每一像素单元121均可显示由三原色组成的任一颜色的画面。
当所述第二液晶单元12103上下加入电场时,所述第二液晶单元12103中的液晶分子垂直于第二偏光器12101的排列方向,即光线与所述第二分析器12106可通过光线方向平行,由于子像素的存在,所述第二显示面板120可显示彩色画面。
通过调节所述第一显示面板110和所述第二显示面板120施加电压大小,可以控制所述显示装置10的明暗和色彩对比度,提高所述显示装置10的显示质量。
如图1所示,本实施例的所述第一显示面板110不设置显示面板,使所述第一显示面板110只显示黑白灰画面,一方面节约了所述显示装置10的制备成本,另一方面也提高了第一显示面板110的穿透率,当所述第一显示面板110的分辨率为1920*1080时,所述第一显示面板110的穿透率可提高108%,当所述第一显示面板110的分辨率为1280*720或960*540时,所述第一显示面板110的穿透率可提高105%。
由于本实施例中,显示装置10为单面显示装置,即第一像素单元111的灰度画面与第二像素单元121的彩色画面重合,形成所述显示装置10的显示画面,由于贴合精度的问题,第一像素单元111和第二像素单元121之间容易照成错位,从而在显示装置10的四周边侧位置形成色偏问题。
如图4所示,所述第一像素单元111超出所述显示区101的距离为1.5个所述第一像素单元111的宽度,超出所述显示区101的所述第一像素单元111不作为所述显示装置10显示画面的像素,主要是用以防止显示装置10的显示区101边缘处形成的色偏现象。
所述第二显示面板120采用主动矩阵电路,通过连接源极驱动芯片130,实现自主发光,实现显示装置的显示效果,通过调节第二像素单元121的自身的亮度,实现第二显示面板120的灰度显示,能够提升显示装置10的分辨率。
第一显示面板110采用被动矩阵电路,不采用源极驱动芯片130结构,因此能够实现大开口率和高分辨率的目的。
本实施例中,所述第一像素单元111的尺寸为248*744um,所述第二像素单元121的尺寸为124*372um,理想状态下,一块第一像素单元111可贴合四块第二像素单元121,但由于目前贴合设备的精度最高只能到达200um,这就使得第二像素单元121无法精准贴合到所述第一像素单元111上,其误差最高可达一个第二像素单元121宽度,这种误差带来的影响在第一显示面板110和第二显示面板120的边缘处最容易体现出来。
为了避免这种现象,本实施例中,将所述第二像素单元121延伸出所述显示区101外,所述第二像素单元121可以自所述第一显示面板110的一端向另一端贴合,如图5所示,也可以自所述第一显示面板110的中部位置向两端贴合,由于所述第一显示面板110超出所述显示区101大约1.5个第一像素单元111的距离,1.5个所述第一像素单元111的距离超过所述目前贴合设备的最大误差,从而可以保证在所述显示区101中的任一所述第二像素单元121均贴合在所述第一像素单元111上,从而有效避免了显示区101由于第二像素单元121和所述第一像素单元111的“错位”问题,提升了所述显示装置10的显示质量。
为了实现所述第一像素单元111向所述边框区102延伸的目标,本实施例中,采用多组源极驱动芯片130连接所述第一像素单元111,具体的,所述源极驱动芯片130设于所述边框区102中,所述源极驱动芯片130通过所述电极导线140连接所述第一像素单元111,同一列的所述第一像素单元111通过同一根所述电极导线140连接至对应的所述源极驱动芯片130上。
任一所述源极驱动芯片130上均设有若干引脚,同一列的所述第一像素单元111通过同一根所述电极导线140连接至对应的引脚上,特别的,位于所述显示区101两侧的所述源极驱动芯片130通道与所述显示区101中部的所述源极驱动芯片130的通道不同,位于所述显示区101两侧的所述源极驱动芯片130通道采用322通道,所述显示区101中部的所述源极驱动芯片130采用320通道,由于所述显示区101两侧的所述源极驱动芯片130型号采用322通道,故其上的引脚比采用320通道源极驱动芯片130的引脚多,能够连接更多的第一像素单元111,从而保证所述第一显示面板110可以延伸到所述边框区102中。
如图6所示,本实施例中,位于所述显示区101两侧的所述源极驱动芯片为SD1和SD6,位于所述显示区101中部的所述源极驱动芯片为SD2、SD3、SD4和SD5。
其中,所述SD1和SD6采用322通道,其可连接1924条导电走线,位于所述显示区101最边侧的导电走线连接的所述第一像素单元的宽度为靠近所述显示区101内侧的所述第一像素单元宽度的一半,特别的,位于所述第一显示面板110四个拐角处的所述第一像素单元其宽度与高度均为靠近所述显示区内侧的所述第一像素单元的一半。
以本实施例中的第一像素单元尺寸为例,本实施例中,所述第一像素单元111的尺寸为744*744,其中,在列方向上,远离所述显示区101的所述第一像素单元尺寸为372*744。
在行方向上,距所述显示区101距离最远的所述第一像素单元111的尺寸为744*372。
在所述第一显示面板110的四个拐角处,所述第一像素单元111的尺寸为372*372。
本发明的显示装置通过第一显示面板和第二显示面板贴合可以提高显示装置的显示质量,第一像素单元自第一显示面板的中间位置贴合,逐步延伸至显示装置的边缘处,由于贴合装置的精度问题,第一显示面板与第二显示面板无法精确贴合,第一显示面板延伸至边框区,第二显示面板也部分延伸至边框区,即使边缘处的第一显示面板和第二显示面板具有误差,也不会影响显示区的正常显示,可以有效避免显示装置的显示区边缘由于第一像素单元和第二像素单元的贴合“错位”造成的色偏现象。
