具体实施方式
为了使本发明的目的,技术方案和优点更加清楚,下面结合附图,对本发明实施例提供的探测面板、其制作方法及检测装置的具体实施方式进行详细地说明。
附图中各层薄膜厚度和形状不反映探测面板的真实比例,目的只是示意说明本发明内容。
相关技术中的探测面板的结构如图1所示,依次包括:衬底基板1、位于衬底基板1上的栅电极2、位于栅电极2上的栅绝缘层3、位于栅绝缘层3上的有源层4、位于有源层4上且位于同一层的漏极5和源极6、位于漏极5和源极6上的第一钝化层7、位于第一钝化层7上的第一树脂层8、位于第一树脂层8上的第二钝化层9、位于第二钝化层9上且与漏极5电连接的第一电极层10、位于第一电极层10上的光电二极管11、位于光电二极管11上的第二电极层12、位于第二电极层12上的缓冲层13、位于缓冲层13上的第二树脂层14、位于第二树脂层14上的第三钝化层15、位于第三钝化层15上且通过贯穿第三钝化层15和第二树脂层14的过孔与光电二极管11电连接的偏置电压层16、位于偏置电压层16上的第四钝化层17、位于绑定区的ITO层18以及位于ITO层18上的闪烁层(图1中未示意出)。
图1所示的探测面板,在检测人员触碰探测面板表面或由于探测面板的清洗工艺不完全时,容易造成静电聚集于探测面板表面,从而探测面板表面由于静电积累导致接触性不良的问题。
有鉴于此,本发明实施例提供了一种探测面板,如图2和图3所示,图2为本发明提供的探测面板的剖面结构示意图,图3为图2所示的部分结构的俯视结构示意图,该探测面板包括:衬底基板10,位于衬底基板10之上的检测电路20,位于检测电路20之上、且与检测电路20电连接的光电转换结构30,以及位于光电转换结构30之上、且与光电转换结构30电连接的偏置电压层40;
偏置电压层40具有网格状结构。
本发明实施例提供的上述探测面板包括:衬底基板10,位于衬底基板10之上的检测电路20,位于检测电路20之上、且与检测电路20电连接的光电转换结构30,以及位于光电转换结构30之上、且与光电转换结构30电连接的偏置电压层40;偏置电压层40具有网格状结构。本发明通过将偏置电压层40设置成网格状结构,当由于检测人员触碰探测面板表面或由于探测面板清洗工艺不完全造成静电聚集于探测面板表面时,网格状结构的偏置电压层40可以将静电及时疏导出,避免静电聚集于探测面板表面某一处,提升探测面板抵抗ESD的能力及减少静电类Mura不良,进而改善探测面板表面由于静电积累导致接触性不良的问题,并且防止静电击伤探测面板。
进一步地,在本发明实施例提供的上述探测面板中,如图2所示,检测电路20包括薄膜晶体管,薄膜晶体管包括位于衬底基板10上依次层叠设置的栅极21、有源层22、源极23和漏极24;有源层22的材料可以是非晶硅、多晶硅、IGZO等半导体材料,源极23和漏极24用于传输数据线与像素极电信号;探测面板还包括:位于栅极21和有源层22之间的栅绝缘层50,位于源漏极(23、24)与光电转换结构30之间的钝化层60,位于钝化层60与光电转换结构30之间的保护层70,保护层70的材料可以为树脂材料,保护层70用于保护有源层22,以防止运输中的水汽影响有源层22的性能。
进一步地,在本发明实施例提供的上述探测面板中,如图2所示,光电转换结构30包括在衬底基板10上依次叠层设置的第一电极31、光电二极管32和第二电极33,第一电极31与薄膜晶体管的漏极24电连接,第二电极33与偏置电压层40电连接。第一电极31用于传导光电二极管32经光照后形成的电信号。工作时,例如向第二电极33施加-5~-10V的电压,使光电二极管32工作在负偏压下,光电二极管32产生不同的电信号,该电信号存储在第一电极31内,第一电极31内存储的电信号通过检测电路20传输至外部IC,以保存图像数据。
进一步地,在本发明实施例提供的上述探测面板中,光电二极管为PIN光电二极管。具体地,PIN光电二极管包括在衬底基板上依次叠层设置的P型区域、N型区域以及介于P型区域和N型区域之间的本征区域。
进一步地,在本发明实施例提供的上述探测面板中,如图3所示,图3示意出了栅极21所在膜层、源漏极(23、24)所在膜层、第一电极31所在膜层和偏置电压层40所在膜层的俯视结构示意图,图3主要是为了示意性说明偏置电压层40具有网格状结构,从而能够将静电及时导出,避免静电聚集于探测面板表面,提升探测面板抵抗ESD的能力及减少静电类Mura不良,进而改善探测面板表面由于静电积累导致接触性不良的问题。
进一步地,在本发明实施例提供的上述探测面板中,如图2所示,为了增大光电二极管32的光转换面积,提升灵敏度,偏置电压层40的材料可以为透明导电材料。
进一步地,在本发明实施例提供的上述探测面板中,如图2所示,第二电极33的材料为透明导电材料。
进一步地,在本发明实施例提供的上述探测面板中,透明导电材料可以为ITO。当然,在具体实施时,透明导电材料不限于ITO,也可以为其它透明导电材料。
进一步地,在本发明实施例提供的上述探测面板中,如图2所示,还包括:位于偏置电压层40与光电转换结构30之间、且覆盖光电转换结构30的缓冲层80,以及位于缓冲层80与偏置电压层40之间、且与偏置电压层40接触设置的树脂层90。具体地,缓冲层80可以增强树脂层90与基底的结合力;另外,由于本发明提供的探测面板中的偏置电压层40的材料为透明导电材料,因此在偏置电压层40与树脂层90之间不需要向相关技术图1那样再设置第三钝化层15和第四钝化层17,这是因为相关技术图1中偏置电压层16的材料为金属,而树脂层90会发生收缩变形,导致金属层断线,所以在金属层两侧需要设置钝化层以隔绝金属层与树脂层接触,因此本发明实施例通过将偏置电压层40的材料设置为透明导电材料,这样可以节省制作偏置电压层40两侧的钝化层,降低制作工艺和成本;并且,由于偏置电压层40的材料为透明导电材料如ITO,因此探测面板绑定区的ITO层和偏置电压层40同层设置,从而进一步减少绑定区的ITO层的设置,进一步降低制作工艺和成本。
进一步地,在具体实施时,在本发明实施例提供的上述探测面板中,如图2所示,还包括:位于偏置电压层40之上的闪烁层100,闪烁层100通过网格状结构的网孔与树脂层90直接接触。具体地,本发明实施例中由于偏置电压层40与树脂层90直接接触,且树脂层90背向偏置电压层40一侧没有钝化层,因此闪烁层100与树脂层直接接触;而相关技术与1中闪烁层是与钝化层直接接触,由于钝化层与闪烁层之间的结合力较弱,在检测过程中容易发生闪烁层脱落,如图4所示,图4为相关技术中闪烁层发生脱落时检测到的图像数据,图4中黑点位置即为闪烁层脱落现象;而由于树脂层90与闪烁层100之间的附着力强度大于钝化层与闪烁层100之间的附着力强度,因此本发明提供的探测面板能够增强闪烁层100与基底之间的结合力,防止闪烁层100脱落,从而不会产生delami不良的问题。
具体地,闪烁层用于将辐射信号转换成光信号,可以使用任何适当的闪烁材料制备闪烁层。在一些实施例中,闪烁材料为将辐射(例如,X射线)转换成可见光的光波长转换材料。闪烁材料可以包括但不限于铊激活的碘化铯、钠激活的碘化铯,碘化铯是一种对光敏感的材料。
具体地,树脂层的材质光透过率较高,透过率一般大于90%,且树脂层制作工艺简单,可通过曝光显影后直接形成所需图形。
基于同一发明构思,本发明实施例还提供了一种探测面板的制作方法,如图5所示,包括:
S501、在衬底基板之上形成检测电路;
S502、在检测电路之上形成光电转换结构;
S503、在光电转换结构之上形成与光电转换结构电连接的偏置电压层;其中,偏置电压层具有网格状结构。
