现有技术中,触控部分一般包括上下两层触控感应层及设置在两层触控感应层之间的绝缘层,考虑到工艺复杂程度的问题,提出直接将触控感应层设置在有机封装层上,但这样会对有机发光二极管(organic light emitting diode, OLED)的阴极或发光层造成伤害,降低了发光效率;还有将触控部分设置在远离OLED的位置,但由于导电电极的线宽不够,会引起发光效率的降低。

可以理解,本申请中的第一触控感应层30是设置在第二无机封装层203上,避免了在制作所述第一触控感应层30时需要用到碱性溶液对OLED的阴极或发光层造成伤害。这里的第一无机封装层201、有机封装层202及第二无机封装层203为基本的封装结构,第一无机封装层201及第二无机封装层203一般通过化学气相沉积(Chemical Vapor Deposition,CVD)沉积形成,有机封装层202一般通过喷墨打印(ink jet printing,IJP)的方式形成。
其中,在所述有机封装层202上相对于所述像素定义层101的位置设置有内凹结构2021,以使后续形成的第二无机封装层203同样相对于所述内凹结构2021存在一内凹部。将所述第一触控感应层30设置在所述内凹部上,以使触控部分在竖直方向上更接近发光单元102,从而可以使触控部分靠近OLED,提高了导电电极的线宽,进而提高了发光效率。
这里的发光单元102为像素区域,一般为R、G、B像素区,但不限于R、G、B、W,这里不做限定,发光单元102是由像素定义层101所隔离。
在一些实施例中,所述发光面板100还包括有胶层60、偏光片70及盖板80,所述胶层60覆盖在所述绝缘层40及所述第二触控感应层50上,所述盖板80及所述偏光片70依次设置在所述胶层60上。其中,所述盖板80由聚酰亚胺或聚酯类化合物组成。
在一些实施例中,所述第一触控感应层30及所述第二触控感应层50由钼、银、钛、铜、铝、钼/铝/钼及钛/铝/钛中任一种组成。

在一些实施例中,所述第一子无机封装层2031中硅原子与氮原子的原子比大于8,所述第二子无机封装层2032中硅原子与氮原子的原子比小于8。
具体的,这里限定第一子无机封装层2031及第二子无机封装层2032中硅原子与氮原子的原子比是为了提高第二无机封装层203的水氧阻隔特性。
在一些实施例中,所述第一无机封装层及所述第二无机封装层203的的竖直厚度为0.1~2μm,相对于所述像素定义层101的竖直厚度为2~20μm,相对于所述像素定义层的所述有机封装层202的竖直厚度比相对于所述发光单元的所述有机封装层202的竖直厚度至少小于1μm。
在一些实施例中,如图4所示,图4为本申请实施例提供的发光面板100中有机封装层202的结构示意图。其中,在所述内凹结构2021上设置有第一凹陷部20211,所述第一凹陷部20211的水平宽度大于所述第一触控感应层30的水平宽度。
可以理解,这里在内凹结构2021上设置第一凹陷部20211的目的在于使后续的第一触控感应层30可以刚好设置在所述第一凹陷部20211内,且所述第一凹陷部20211的水平宽度大于所述第一触控感应层30的水平宽度,这里是为了在后续制备中诸如第二无机封装层203或绝缘层40也可设置在所述第一凹陷部20211内,提高了制备过程中第一触控感应层30及第二触控感应层50的对位精度。
在一些实施例中,请参阅图5,图5为本申请实施例提供的发光面板100中第一无机封装层201的结构示意图。其中,在相对于所述像素定义层101的所述第一无机封装层201上还设置有第二凹陷部2011。
可以理解,这里在相对于所述像素定义层101的所述第一无机封装层201上设置第二凹陷部2011的作用与在所述内凹结构2021上设置第一凹陷部20211的作用相同,都是为了在后续制备过程中,第一触控感应层30可以设置在所述第一凹陷部20211内,提高了制备过程中第一触控感应层30及第二触控感应层50的对位精度。
