Description

像素结构、阵列基板及显示装置
技术领域
本发明涉及液晶显示技术领域,尤其涉及一种像素结构、一种具有该像素结构的阵列基板及一种应用该阵列基板的显示装置。
背景技术
随着触摸屏技术的不断发展,触控(Touch)和显示(Display)不再是两种独立的技术形式,越来越多的薄膜晶体管型液晶显示屏(ThinFilmTransistor-LiquidCrystalDisplay,TFT-LCD)厂家开始尝试将Touch和Display两者进行有机的结合,内嵌式触控(In-CellTouch)、单片式触控(OneGlassSolution,OGS)、覆盖表面式触控(On-CellTouch)和混合内嵌式触控(HybridIn-CellTouch)等将Touch和Display相结合的触控技术竞相涌现。
相比OGS、On-CellTouch或HybridIn-CellTouch面板,In-CellTouch面板具备更加轻薄、工艺流程更少、结构更加稳定等优点。In-CellTouch技术将触控电路全部集成在LCD内部,无须再外贴触控感应玻璃(TouchSensorGlass)或者在LCD上面再进行On-Cell制程,从而实现了集成化及缩短了生产流程和生产时间,使得LCD生产厂商的利润更大化。同时,通过使用高分辨的曝光机,可以实现In-CellTouch面板更高的分辨率,并能有效防止莫瑞干涉。因此,In-CellTouch面板将成为中小尺寸触控面板未来发展的主流方向。
在In-CellTouch面板的生产过程中,需要在阵列基板上设计为了触控显示的电极和走线,如采用低温多晶硅(LowTemperaturePoly-silicon,LTPS)阵列,其阵列制程比传统的传统非晶硅(α-Si)制程复杂得多。所以In-CellTouch和LTPS的集成不但会使得阵列制程更加复杂,生产周期更长,而且对阵列制程的要求也更加严格。
In-CellTouch面板一般可分为自容式和互容式,二者都需要用于连接像素区域的连接电极,因此制程上会增加一道或两道光刻(PhotoEngravingProcess,PEP)制程来制作连接像素区域的连接电极(或称作Metal3或M3)和相应的绝缘层。增加的M3制程会对产品的良率产生风险,因为M3的刻蚀制程会导致斑纹(Mura)缺陷。然而,在In-CellTouch技术中又不得不采用M3以连接像素区域,因此一定程度上限制了In-CellTouch面板良率提升。
发明内容

可以理解,所述第一连接层51与所述栅极21和所述扫描线110位于同一图层,所述第二连接层53与所述源极23、漏极25和所述数据线130位于同一图层。因此,所述第一连接层51可以与所述栅极21和扫描线110在同一次制作工艺中同步形成,所述第二连接层53可以与所述源极23、漏极25和所述数据线130在同一次制作工艺中同步形成。进一步地,通过所述第一过孔H1将所述第一连接层51和所述第二连接层53电性连接,形成用于连接所述像素区域150的连接电极50,从而无需单独增加一道或多道制作工艺来形成所述连接电极50,简化了工艺流程。

可以理解,所述第一连接层51与所述栅极g和所述扫描线210位于同一图层,所述第二连接层53与所述源极g、漏极d和所述数据线230位于同一图层。因此,所述第一连接层51可以与所述栅极g和扫描线210在同一次制作工艺中同步形成,所述第二连接层53可以与所述源极s、漏极d和所述数据线230在同一次制作工艺中同步形成。进一步地,通过所述第一过孔H1将所述第一连接层51和所述第二连接层53电性连接,形成用于连接所述像素区域250的连接电极50,从而无需单独增加一道或多道制作工艺来形成所述连接电极50,简化了制造所述阵列基板200的工艺流程。
