Description
技术领域

背景技术
随着显示技术的发展,压感显示面板被越来越多地应用在手机或平板电脑等电子产品上。压感显示面板能够检测用户对压感显示面板的按压力度,进而根据用户的按压力度,显示相应的图像。

附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图5-3为本发明实施例提供的又一种低温多晶硅显示面板中阵列基板的局部结构示意图;
图5-4为本发明实施例提供的一种低温多晶硅显示面板中阵列基板的结构示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
如图1所示,本发明实施例提供了一种压感显示面板0,该压感显示面板0可以包括:低温多晶硅(英文:Low Temperature Poly-silicon;简称:LTPS)显示面板01,以及设置在低温多晶硅显示面板01入光侧的预设电极02;
低温多晶硅显示面板01中的阵列基板011包括:衬底基板11,以及形成在衬底基板11上材质为导体的预设功能层12;其中,预设功能层12在衬底基板11上的正投影区域与预设电极02在衬底基板11上的正投影存在重叠区域,且预设功能层12和预设电极02均与压感控制单元1相连接。
综上所述,本发明实施例提供了一种压感显示面板,由于该压感显示面板包括低温多晶硅显示面板以及设置在低温多晶硅显示面板入光侧的预设电极,且该低温多晶硅显示面板中的预设功能层以及预设电极均与压感控制单元相连接,该低温多晶硅显示面板中的预设功能层可以作为压感单元中的辅助电极,也即本发明中低温多晶硅显示面板的入光侧仅仅设置有预设电极,无需在低温多晶硅显示面板的入光侧设置辅助电极和绝缘层,因此,减小了压感显示面板的厚度。
可选的,预设功能层12可以包括遮光(英文:Light Shield;简称:LS)图案121和辅助电极122,辅助电极122在衬底基板11上的正投影区域与预设电极121在衬底基板11上的正投影区域存在重叠区域(如该重叠区域可以与辅助电极122的形状和大小完全相同),且与遮光图案121在衬底基板11上的正投影区域不重叠,辅助电极122与压感控制单元1相连接。由于遮光图案121与相关技术中的遮光图案在低温多晶硅显示面板中所起到的作用相同,且遮光图案121设置在低温多晶硅显示面板中的薄膜晶体管(英文:Thin FilmTransistor;简称:TFT)沟道的下方,遮光图案121在衬底基板11上的正投影区域与辅助电极122在衬底基板11上的正投影区域不重叠,也即辅助电极122并未设置在TFT沟道的下方,在对辅助电极施加电压时,辅助电极上的电压不会对TFT沟道产生影响。优选的,本发明实施例中的遮光图案与辅助电极相互独立,也即遮光图案与辅助电极不相连接,在向辅助电极输入电压时,遮光图案上未输入电压。
示例的,该材质为导体的预设功能层可以为低温多晶硅显示面板中的任意一个材质为导体的膜层。需要说明的是,图1所示的压感显示面板0中,低温多晶硅显示面板01中的彩膜基板(图1中未示出)包括黑矩阵(图1中未示出),辅助电极122在阵列基板011的衬底基板11上的正投影区域位于彩膜基板中的黑矩阵在阵列基板011的衬底基板11上的正投影区域内。也即,彩膜基板中的黑矩阵能够有效的将本发明中的辅助电极进行遮挡,从而使得本发明实施例中的辅助电极不会影响该压感显示面板的显示。进一步的,本发明实施例中的预设电极02可以为设置在低温多晶硅显示面板入光侧的中框。
进一步的,形成有预设功能层12的衬底基板11上还依次形成有缓冲层13、有源层14、栅绝缘层15、栅极图案16、中间介电层17和源漏极图案18;其中,源漏极图案18可以包括:源极181、漏极182和屏蔽电极183,辅助电极122在衬底基板11上的正投影区域位于屏蔽电极183在衬底基板11上的正投影区域内。由于衬底基板11上形成有屏蔽电极183,且屏蔽电极183位于辅助电极122和低温多晶硅显示面板的出光侧之间,在用户使用手指触摸压感显示面板0时,由于用户手指为导体,用户手指会对用户手指附近的电极上的电压产生影响,又由于屏蔽电极183设置在辅助电极122与用户手指之间,因此,该屏蔽电极183能够防止用户手指对该辅助电极122上的电压的影响。
形成有源漏极图案18的衬底基板11上还依次形成有平坦层19、公共电极图案20、钝化层21和像素电极图案22;其中,公共电极图案20可以包括阵列排布的多个公共电极,多个公共电极包括至少一个触控公共电极(也即用于触控的公共电极),每个触控公共电极通过平坦层19上的过孔G与一个屏蔽电极183相连接,且任意两个触控公共电极所连接的屏蔽电极183不同,每个与触控公共电极相连接的屏蔽电极183与触摸控制单元2相连接。由于低温多晶硅显示面板中的触控公共电极与屏蔽电极183相连接,且屏蔽电极183还连接至触摸控制单元2,也即,该触控公共电极可以作为自容式的触控电极,且屏蔽电极可以作为连接触控电极与触摸控制单元2的触摸控制线,从而实现了压感显示面板的触控功能,还减薄了具有触控功能的压感显示面板的厚度。
图2为本发明实施例提供的一种压感显示面板0的局部结构示意图,如图2所示,低温多晶硅显示面板上可以设置有多个公共电极,且每个公共电极均为触控公共电极(也即每个公共电极均通过过孔与一个屏蔽电极183相连接),每个公共电极对应十二个像素电极221。该低温多晶硅显示面板上可以形成有多条触摸控制线(也即图1中的屏蔽电极183),其中,触摸控制线M1通过过孔G1与公共电极211相连接,触摸控制线M2通过过孔G2与公共电极212相连接,也即该公共电极211可以为与触摸控制线M1相连接的触控电极,公共电极212可以为与触摸控制线M2相连接的触控电极。在进行触摸控制的时候,该触摸控制单元2可以通过触摸控制线M1向公共电极211输入触控信号,确定压感显示面板上公共电极211所在区域是否被用户触摸,以及通过触摸控制线M2向公共电极212输入触控信号,确定压感显示面板上公共电极212所在区域是否被用户触摸。
可选的,辅助电极包括有效辅助电极和连接辅助电极,有效辅助电极通过连接辅助电极与压感控制单元相连接,衬底基板上某一区域对应的有效面积为第一有效面积与第二有效面积的和,第一有效面积为:位于某一区域内的有效辅助电极在衬底基板上的正投影区域与预设电极在衬底基板上的正投影区域的重叠面积,第二有效面积为:与某一区域内的有效辅助电极相连接的连接辅助电极在衬底基板上的正投影区域与预设电极在衬底基板上的正投影区域的重叠面积;衬底基板上靠近压感控制单元的区域对应的有效面积,大于衬底基板上远离压感控制单元的区域对应的有效面积。
图3为本发明实施例提供的另一种压感显示面板的局部结构示意图,如图3所示,条状电极X1和条状电极X2通过条状电极U1连接在一起,并且通过条状电极U1连接至压感控制单元1;条状电极Y1和条状电极Y2通过条状电极U2和条状电极Z连接在一起,并且通过条状电极U2连接至压感控制单元1。
条状电极X1、条状电极X2、条状电极Y1、条状电极Y2以及条状电极Z均为衬底基板01上的有效辅助电极,条状电极U1和条状电极U2均为衬底基板01上的连接辅助电极,其中,条状电极X1与条状电极X2均形成在衬底基板01上的第一区域L1,条状电极Y1、条状电极Y2以及条状电极Z均形成在衬底基板01上的第二区域L2,第一区域L1远离压感控制单元1,第二区域L2靠近压感控制单元1。
第一区域L1内的条状电极X1和条状电极X2在衬底基板01上的正投影区域与预设电极在衬底基板01上的正投影区域的重叠面积,以及条状电极U1在衬底基板01上的正投影区域与预设电极在衬底基板01上的正投影区域的重叠面积之和,为第一区域L1的衬底基板01对应的有效面积。第二区域L2内的条状电极Y1和条状电极Y2在衬底基板01上的正投影区域与预设电极在衬底基板01上的正投影区域的重叠面积,以及条状电极U2和条状电极Z在衬底基板01上的正投影区域与预设电极在衬底基板01上的正投影区域的重叠面积之和,为第二区域L2的衬底基板01对应的有效面积。且从图3能够直观的看出,第一区域L1距离压感控制单元1较远,第二区域L2距离压杆控制单元1较近。且每个区域对应的有效面积与该区域对应的电容成正比,也即,随着该区域对应的有效面积的增大,该区域对应的电容也会增大。
第一区域L1对应的电阻为:条状电极X1、条状电极X2以及条状电极U1对应的电阻(包括条状电极X1、条状电极X2以及条状电极U1形成的电阻);第二区域L2对应的电阻为:条状电极Y1、条状电极Y2、条状电极U2以及条状电极Z对应的电阻(包括条状电极Y1、条状电极Y2、条状电极U2形成的电阻)。第一区域L1对应的电容为:条状电极X1、条状电极X2以及条状电极U1对应的电容(包括条状电极X1、条状电极X2以及条状电极U1形成的电容);第二区域L2对应的电容为:条状电极Y1、条状电极Y2、条状电极U2以及条状电极Z对应的电容(包括条状电极Y1、条状电极Y2、条状电极U2以及条状电极Z形成的电容)。
可见,第一区域L1对应的电阻大于第二区域L2对应的电阻,第一区域L1对应的电容小于第二区域L2对应的电容。条状电极X1、条状电极X2以及条状电极U1对应的电阻和电容的乘积,与条状电极Y1、条状电极Y2、条状电极U2以及条状电极Z对应的电阻和电容的乘积趋于一致,使得该压感显示面板0上的各个区域的电阻和电容的乘积均趋于一致,从而有效的提高了压感显示面板的显示效果。
也即,图3中辅助电极包括至少两个第一条状电极(如图3中的条状电极X1和条状电极X2)和至少一个第二条状电极(如图3中的条状电极U1、条状电极U2或条状电极Z),第一条状电极的长度方向垂直于第二条状电极的长度方向,第2n+1个第一条状电极与第2n+2个第一条状电极通过至少一个第二条状电极相连接,n为大于或等于0的整数。示例的,辅助电极122可以包括至少四个第一条状电极,第2n+1个第一条状电极、第2n+2个第一条状电极、第2n+3个第一条状电极与第2n+4个第一条状电极沿远离压感控制单元到靠近压感控制单元的方向依次排布,也即,第2n+1个第一条状电极和第2n+2个第一条状电极位于衬底基板11上靠近压感控制单元的区域,第2n+3个第一条状电极与第2n+4个第一条状电极位于衬底基板11上远离压感控制单元的区域。第2n+1个第一条状电极与第2n+2个第一条状电极通过p个第二条状电极相连接,第2n+3个第一条状电极与第2n+4个第一条状电极通过q个第二条状电极相连接,p和q均为大于或等于1的整数,且q大于p。
衬底基板上第2n+1个第一条状电极和第2n+2个第一条状电极所在的区域对应的有效面积,大于衬底基板上第2n+3个第一条状电极与第2n+4个第一条状电极所在的区域对应的有效面积。
综上所述,本发明实施例提供了一种压感显示面板,由于该压感显示面板包括低温多晶硅显示面板以及设置在低温多晶硅显示面板入光侧的预设电极,且该低温多晶硅显示面板中的预设功能层以及预设电极均与压感控制单元相连接,该低温多晶硅显示面板中的预设功能层可以作为压感单元中的辅助电极,也即本发明中低温多晶硅显示面板的入光侧仅仅设置有预设电极,无需在低温多晶硅显示面板的入光侧设置辅助电极和绝缘层,因此,减小了压感显示面板的厚度。
如图4所示,本发明实施例提供了一种压感显示面板的制造方法,该压感显示面板的制造方法可以包括:
步骤401、制造低温多晶硅显示面板,低温多晶硅显示面板中的阵列基板包括:衬底基板,以及形成在衬底基板上材质为导体的预设功能层;
步骤402、在低温多晶硅显示面板入光侧的设置预设电极,预设功能层在衬底基板上的正投影区域与预设电极在衬底基板上的正投影区域存在重叠区域;
步骤403、将预设功能层和预设电极均连接至压感控制单元,形成压感显示面板。
综上所述,本发明实施例提供了一种压感显示面板的制造方法,由于该方法所制造的压感显示面板包括低温多晶硅显示面板以及设置在低温多晶硅显示面板入光侧的预设电极,且该低温多晶硅显示面板中的预设功能层以及预设电极均与压感控制单元相连接,该低温多晶硅显示面板中的预设功能层可以作为压感单元中的辅助电极,也即本发明中低温多晶硅显示面板的入光侧仅仅设置有预设电极,无需在低温多晶硅显示面板的入光侧设置辅助电极和绝缘层,因此,减小了压感显示面板的厚度。
需要说明的是,本发明实施例中的预设电极为设置在低温多晶硅显示面板入光侧的中框。可选的,如图5-1所示,步骤401中制造低温多晶硅显示面板时,可以分别制造低温多晶硅显示面板的阵列基板和彩膜基板,然后将阵列基板与彩膜基板进行对盒,得到液晶盒,并在液晶盒中滴注液晶,得到该低温多晶硅显示面板。制造低温多晶硅显示面板中的彩膜基板的具体方法可以参考相关技术中制造彩膜基板的具体方法,本发明实施例在此不做赘述。
具体的,在制造低温多晶硅显示面板中的阵列基板时,可以首先在衬底基板11上涂覆遮光金属K,然后采用一次构图工艺对该遮光金属K进行处理形成如图5-2所示的预设功能层12。预设功能层12可以包括遮光图案121和辅助电极122,辅助电极122在衬底基板11上的正投影区域与预设电极在衬底基板11上的正投影区域存在重叠区域,且与遮光图案121在衬底基板11上的正投影区域不重叠,辅助电极122可以与压感控制单元相连接。该一次构图工艺可以包括光刻胶涂覆、曝光、显影、刻蚀和剥离。
在形成预设功能层12后,如图5-3所示,可以在形成有预设功能层12的衬底基板11上依次形成缓冲层13、有源层14、栅绝缘层15、栅极图案16、中间介电层17和源漏极图案18,需要说明的是,该源漏极图案18可以包括:源极181、漏极182和屏蔽电极183,辅助电极122在衬底基板11上的正投影区域位于屏蔽电极183在衬底基板11上的正投影区域内。需要说明的是,在形成源漏极图案18时,也可以首先在栅绝缘层上形成一层金属层,然后采用一次构图工艺对形成的金属层进行处理,得到该源漏极图案18,由于本发明实施例中的源漏极图案18与相关技术中的源漏极图案不同,因此,本发明实施例中在形成源漏极图案18时采用的掩膜板与相关技术中形成源漏极图案的掩膜板不同。
然后,如图5-4所示,可以在形成有源漏极图案18的衬底基板11上依次形成平坦层19、公共电极图案20、钝化层21和像素电极图案22。其中,公共电极图案20可以包括阵列排布的多个公共电极,多个公共电极可以包括至少一个触控公共电极,每个触控公共电极通过平坦层上的过孔(也即,在形成平坦层后,还需要在平坦层上形成过孔,之后才在形成有过孔的平坦层上形成公共电极图案)与一个屏蔽电极相连接,且任意两个触控公共电极所连接的屏蔽电极不同,每个与触控公共电极相连接的屏蔽电极与触摸控制单元相连接。
本发明实施例中,辅助电极包括有效辅助电极和连接辅助电极,有效辅助电极通过连接辅助电极与压感控制单元相连接,衬底基板上某一区域对应的有效面积为第一有效面积与第二有效面积的和,第一有效面积为:位于某一区域内的有效辅助电极在衬底基板上的正投影区域与预设电极在衬底基板上的正投影区域的重叠面积,第二有效面积为:与某一区域内的有效辅助电极相连接的连接辅助电极在衬底基板上的正投影区域与预设电极在衬底基板上的正投影区域的重叠面积;衬底基板上靠近压感控制单元的区域对应的有效面积,大于衬底基板上远离压感控制单元的区域对应的有效面积。低温多晶硅显示面板中的彩膜基板包括黑矩阵,辅助电极在衬底基板上的正投影区域位于黑矩阵在衬底基板上的正投影区域内。
辅助电极可以包括至少两个第一条状电极和至少一个第二条状电极,第一条状电极的长度方向垂直于第二条状电极的长度方向,第2n+1个第一条状电极与第2n+2个第一条状电极通过至少一个第二条状电极相连接,n为大于或等于0的整数。示例的,辅助电极包括至少四个第一条状电极,第2n+1个第一条状电极、第2n+2个第一条状电极、第2n+3个第一条状电极与第2n+4个第一条状电极沿远离压感控制单元到靠近压感控制单元的方向依次排布,第2n+1个第一条状电极与第2n+2个第一条状电极通过p个第二条状电极相连接,第2n+3个第一条状电极与第2n+4个第一条状电极通过q个第二条状电极相连接,q和q均为大于或等于1的整数,且q大于p。
综上所述,本发明实施例提供了一种压感显示面板的制造方法,由于该方法所制造的压感显示面板包括低温多晶硅显示面板以及设置在低温多晶硅显示面板入光侧的预设电极,且该低温多晶硅显示面板中的预设功能层以及预设电极均与压感控制单元相连接,该低温多晶硅显示面板中的预设功能层可以作为压感单元中的辅助电极,也即本发明中低温多晶硅显示面板的入光侧仅仅设置有预设电极,无需在低温多晶硅显示面板的入光侧设置辅助电极和绝缘层,因此,减小了压感显示面板的厚度。
本发明实施例提供了一种压感显示装置,该压感显示装置可以包括图1、图2或图3所示的压感显示面板0。该压感显示装置可以为:液晶面板、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
综上所述,本发明实施例提供了一种压感显示装置,由于该压感显示装置中的压感显示面板包括低温多晶硅显示面板以及设置在低温多晶硅显示面板入光侧的预设电极,且该低温多晶硅显示面板中的预设功能层以及预设电极均与压感控制单元相连接,该低温多晶硅显示面板中的预设功能层可以作为压感单元中的辅助电极,也即本发明中低温多晶硅显示面板的入光侧仅仅设置有预设电极,无需在低温多晶硅显示面板的入光侧设置辅助电极和绝缘层,因此,减小了压感显示面板的厚度。
所属领域的技术人员可以清楚地了解到,为描述的方便和简洁,上述描述的压感显示面板实施例、压感显示面板的制造方法实施例以及上述描述的压感显示装置实施例均可以互相参考,在此不再赘述。
以上所述仅为本发明的较佳实施例,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
