Description

显示面板及其制造方法与显示装置 技术领域
本申请涉及一种制造方式,特别是涉及一种显示面板及其制造方法与显示装置。
背景技术
最近开发了多种类型的平板显示设备来代替笨重的阴极射线管。平板显示设备包括液晶显示器、等离子体显示面板、电泳显示器和有机发光显示器。目前,高像素的平面显示面板为市场的趋势,AMOLED(Active Matrix及Organic Light Emitting Diode,有源矩阵有机发光二极管面板)面板吸引了众人的目光,且AMOLED(Active Matrix及Organic Light Emitting Diode,有源矩阵有机发光二极管面板)面板在中小尺寸、像素为200ppi的面板市场中占据主导地位,且AMOLED WVGA(Wide Video Graphics Array,高于VGA分辨率的一种分辨率:800*480;~200ppi)为目前的主流分辨率,而高像素250ppi、300ppi以及350ppi将会是未来的发展趋势。现有的AMOLED面板的生产方式以Side by Side(并排)技术为主,然而所述技术在生产300ppi及以上的产品具有一定的困难度。因此业界会采用另一种实现方式来制作AMOLED面板:WOLED(White Organic Light Emitting Diode,白光有机发光二极管)加彩色滤片(Color Filter,CF)的方式。由于WOLED可以采用全开口的金属屏蔽进行蒸镀,因此有可能实现高像素的画质。且有机发光装置(Organic light emitting device,OLED)因其自发光、无视角依存、省电、制程简易、低成本、低温度操作范围、高应答速度以及全彩化等优点而具有极大的应用潜力,可望成为新世代平面显示器的照明光源主流。
而自发光显示屏具有高对比度、广色域、响应速度快等特点。由于不需使用背光板,因此比液晶显示器更能够做得更轻薄甚至柔性。自发光显示器的主要通过特定的主动开关阵列进行控制调节发光器件的开关和亮度,在调节三原色的比例之后进行画面显示。其中,控制主动开关阵列往往采用金属氧化物半导体,其不仅有较高的开态电流和较低的关态电流,还有均匀性和稳定性较高的特点。OLED(Organic Light Emitting Diode,有机发光二极管)的基本结构是由一薄而透明具半导体特性的铟锡氧化物(ITO),与电力的阳极相连,再加上另一个金属阴极,包成如三明治的结构,其中整个结构层中至少包括:电洞注入层(HIL)、电洞传输层(HTL)、发光层(EL)、电子注入层(EIL)及电子传输层(ETL)。当电力供应至适当电压时,阳极电洞与阴极电荷就会在发光层结合,产生光亮,其依配方不同产生红、绿及蓝三原色,构成基本色彩。但往往需要增加传感器制程,以造成制造成本过高。
