本申请要求于2021年03月29日提交的申请号为2021103351993,发明名称为“一种显示基板、显示面板及其驱动方法”的中国专利申请的优先权,其通过引用方式全部并入本申请。
技术领域
本申请属于显示技术领域,具体涉及一种显示基板、显示面板、显示面板驱动方法及电子设备。
背景技术
现有技术中,电子设备的显示屏在息屏状态时一般呈单调的黑色状态。
针对显示屏在息屏状态下显示过于单调的问题,虽然可以通过显示屏保的方式呈现多彩图案,但因为显示屏保时显示屏仍处于工作状态,上述方式势必会增加显示屏功耗,导致电池电量的使用时长缩短,进而影响用户体验。
发明内容
本申请实施例的目的是提供一种显示基板、显示面板、显示面板驱动方法及电子设备,能够解决现有显示屏在不需要使用时无法低功耗呈现彩色的问题。
为了解决上述技术问题,本申请是这样实现的:
第一方面,本申请实施例提供了一种显示基板,其中,包括衬底及设置于所述衬底上的像素界定层;
所述像素界定层包括间隔设置的多个像素界定部,每个所述像素界定部远离所述衬底一侧层叠设置有第一电极、电致变色层及第二电极;
所述像素界定层位于所述衬底与所述第一电极之间;
所述电致变色层可在所述第一电极与所述第二电极的电场作用下发生变色反应。
第二方面,本申请实施例提供了一种显示面板,其中,所述显示面板包括如上所述的显示基板。
第三方面,本申请实施例提供了一种显示面板驱动方法,所述驱动方法用于对如上所述的显示面板进行驱动,其中,所述驱动方法包括:
在息屏状态下,在所述触控驱动电极与所述第一电极之间施加第一电压,以使所述电致变色层由原色变化至目标色,所述原色为黑色或灰色。
第四方面,本申请实施例提供了一种电子设备,该电子设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令,所述程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。
第五方面,本申请实施例提供了一种可读存储介质,所述可读存储介质上存储程序或指令,所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
第六方面,本申请实施例提供了一种芯片,所述芯片包括处理器和通信接口,所述通信接口和所述处理器耦合,所述处理器用于运行程序或指令,实现如第一方面所述的方法。
在本申请实施例中,显示基板包括衬底及设置于上述衬底上的像素界定层;上述像素界定层包括间隔设置的多个像素界定部,每个上述像素界定部远离衬底一侧层叠设置有像素界定层、第一电极、电致变色层及第二电极;上述像素界定层位于上述衬底与上述第一电极之间;上述电致变色层可在上述第一电极与上述第二电极的电场作用下发生变色反应。上述显示基板,在位于像素界定部上的第一电极上增加电致变色层及第二电极,将上述显示基板应用于显示面板中时,因为电致变色层可在电场作用下发生可逆的变色反应,因而可以在显示面板息屏时,通过在第一电极与第二电极上施加电压,使得电致变色层进行变色调整,进而使得整个显示面板呈现多彩状态;另外, 因为电致变色层在颜色不发生变化的情况下不会再消耗电能,上述多彩图案的呈现方式的功耗远低于现有屏保方式的功耗。
本申请的附加方面和优点将在下面的描述中部分给出,部分将从下面的描述中变得明显,或通过本申请的实践了解到。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”,一般表示前后关联对象是一种“或”的关系。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的显示基板进行详细地说明。
请参阅图1~3,上述显示基板10包括衬底101及设置于所述衬底101上的像素界定层102;上述像素界定层102包括间隔设置的多个像素界定部103, 每个像素界定部103远离上述衬底101一侧依次层叠设置有第一电极105、电致变色层106及第二电极107;上述电致变色层106可在上述第一电极105与上述第二电极107的电场作用下发生变色反应。
本申请实施例所提供的显示基板还包括触控层110,上述触控层位于第一电极105远离衬底101一侧,且位于第二电极107远离衬底101一侧,以避免电致变色层的设置对触控层功能的实现造成影响。
上述触控层110包括触控驱动电极及触控感应电极,上述触控驱动电极位于触控层110朝向衬底101一侧,上述触控感应电极位于触控层110远离衬底101一侧;当触控发生时,触控点附近的触控驱动电极与触控感应电极之间的距离会发生变化,使得二者之间的电容耦合受到影响而产生感应信号,进而可计算出触控点位置。
本申请实施例中,相邻像素界定部103之间的区域设置有子像素单元104;上述显示基板10还包括多个薄膜晶体管109,多个薄膜晶体管109均位于上述衬底101与上述像素界定层102之间,且每个子像素单元104经由对应的第三电极108电性连接一个上述薄膜晶体管109,上述薄膜晶体管109用于给上述第二电极108施加驱动信号,且每个上述子像素单元104远离上述衬底101一侧与上述第一电极105导通或接触,然后将第一电极105与第三电极108中二者之一作为阳极,并将第一电极105与第三电极108中二者之另一作为阴极,并结合上述薄膜晶体管109的开关作用,即可以实现控制相应子像素单元的发光或不发光。其中,上述子像素单元104可以为OLED像素子单元,具体可以为红光像素子单元、绿光像素子单元或蓝光像素子单元。其中,上述阴极及触控驱动电极的材质可以为金属银Ag、铜Cu、镁Mg、铝Al、金属网格Metal Mesh、金属氧化物ITO、氧化铟锡中的一种或多种。
上述薄膜晶体管包括依次位于衬底101之上的缓冲层91、铟镓锌氧化物(Indium Gallium Zinc Oxide,IGZO)有源层92、栅绝缘层93、栅极94、层间介质层95,在层间介质层之上的源极(S极)96、漏极(D极)97,覆盖源极96、漏极97、栅极94的平坦化层98;上述第三电极108与上述漏极94 连接。
可选地,在一个薄膜晶体管中,包括由N个上述源极96、漏极97、栅极94组成的单元,且前一个单元的漏极97与下一个单元的栅极94连接,且第一个单元的源极96与控制电路的阳极连接,而第N个单元的漏极94与上述第三电极108连接。其中,上述N为正整数,例如为1、2或9。
本申请实施例中,上述子像素单元104上覆盖有上述第一电极105,且在第一电极105上依次层叠设置有薄膜封装层113及聚酰亚胺薄膜层114,实现对子像素单元的封装。
本申请实施例中,因为电致变色层106位于第二电极107及位于显示界定部103上的第一电极105之间,且电致变色层106可在电场作用下发生可逆的变色反应,因而将上述显示基板10应用在显示面板20中时,可以在显示面板20息屏时,通过在第二电极107与第一电极105之间施加达到电致变色层106的变色电压值的电压,即可以使得电致变色层106进行变色调整;
同时,因为每个像素界定部103远离衬底一侧均依次层叠设置有第一电极105、电致变色层106及第二电极107,通过控制不同位置的电致变色层106进行颜色变化,即可以使得整个显示面板20呈现多彩状态;
另外,因为电致变色层106在颜色不发生变化的情况下不会再消耗电能,上述多彩图案的呈现方式的功耗远低于现有屏保方式的功耗。
其中,因为上述第一电极105为现有显示基板10的固有电极结构,且因为在显示面板20处于息屏状态下时,上述第一电极105无需用于为显示面板20显示画面供电,上述第二电极107为单独设置的用于为电致变色层进行变色反应提供电场作用的电极,因而上述电致变色层106变色调整的实现不会影响显示面板20的原有显示功能。
本申请实施例中,上述电致变色层106包括依次层叠设置的电致变色材料子层61、离子传导子层62及离子储存子层63。其中,离子传导子层66位于电致变色材料子层61及离子储存子层62之间,且离子传导子层63与电致变色材料子层61及离子储存子层62均直接接触。
其中,电致变色材料层106的材料的光学属性如反射率、透过率、吸收率等在外加电场的作用下发生稳定、可逆的颜色变化的现象,其可以为无机电致变色材料或有机电致变色材料。可选地,上述电致变色材料子层61的材料具体可以为聚吡咯类电致变色材料、聚噻吩类电致变色材料、聚呋喃类电致变色材料和聚吲哚类电致变色材料中的一种或多种。聚苯胺可以通过电化学过程或者苯胺的化学氧化形成;在不同的氧化态下,聚苯胺可以呈现为浅黄色或者深绿/黑色。
其中,离子传导子层62允许离子在电致变色子层61和离子储存子层63之间移动,但是会阻止电子通过,也即上述离子传导子层62导离子而不导电子,其型态可以为固态、液态或胶态。
其中,离子储存子层63有储存离子的功用,并在变色过程中供应所需的离子,起到平衡电荷总量的作用。离子储存子层63也可以使用与电致变色材料子层61的电致变色材料性能相反的电致变色材料,可以在变色过程中起到离子互补的作用。
可选地,在一种实施方式中,上述电致变色材料子层61与第一电极电连接105,上述离子储存子层63与上述第二电极107电连接。在本实施方式中,电致变色材料子层61与第一电极105接触,而离子储存子层63与第二电极107接触,使得在电致变色层106进行变色调整时,于靠近第一电极105一侧进行变色反应。
可选地,在另一种实施方式中,上述离子储存子层63与第一电极电105连接,上述电致变色材料子层61与上述第二电极107电连接。在本实施方式中,电致变色材料子层61与第二电极107接触,而离子储存子层63与第一电极105接触,使得在电致变色层106进行变色调整时,于远离第一电极105一侧进行变色反应。
可选地,上述电致变色材料子层61在电致变色前呈黑色或灰色。本申请实施例中的电致变色材料子层61在电致变色前呈黑色或灰色,使得包括上述显示基板10的显示面板20进行通电显示时,利用呈黑色或灰色的电致变色 层对电致变色层106的投影区域进行遮光,提示画面显示效果。
可选地,在一种实施方式中,如图3所示,本申请实施例所提供的显示基板中,上述电致变色层106位于上述第一电极105朝向上述衬底101的一侧;;相应地,因为第一电极105、电致变色层106及第二电极层107叠设置,因而上述第二电极107则位于电致变色层106朝向上述衬底101的一侧。在上述实施方式中,电致变色层106及第二电极107可嵌入像素界定部103内部,可以在不增加显示基板厚度的前提下实现变色功能。
可选地,在一种实施方式中,如图4所示,本申请实施例所提供的显示基板10中,上述电致变色层106位于上述第一电极105远离上述衬底101的一侧;相应地,因为第一电极105、电致变色层106及第二电极层107叠设置,因而上述第二电极107则位于电致变色层106远离上述衬底101的一侧。在上述实施方式中,电致变色层106及第二电极107可嵌入第一电极105上部的封装层内部,不仅可以在不增加显示基板厚度的前提下实现变色功能,还使得电致变色层更接近显示基板表层,使得电致变色层的颜色显示效果更佳。
本申请实施例还提供了一种显示面板,请继续参阅图3或4,上述显示面板20包括上述显示基板10。
上述显示面板中,在第二电极及位于显示界定部上的第一电极之间增加电致变色层,因为电致变色层可在电场作用下发生可逆的变色反应,因而可以在显示面板息屏时,通过在第二电极与第一电极上施加电压,使得电致变色层进行变色调整,进而使得整个显示面板呈现多彩状态;另外,因为电致变色层在颜色不发生变化的情况下不会再消耗电能,上述多彩图案的呈现方式的功耗远低于现有屏保方式的功耗。
可选地,如图3或4所示,上述显示面板20还包括盖板111和触控层110;上述盖板111、上述触控层110以及上述显示基板10依次层叠设置,上述盖板111与上述触控层110之间通过光学透明胶112粘结。因为在显示面板20处于显示状态时,电致变色层106呈黑色或灰色等暗颜色状态,可以对底下 薄膜晶体管109等线路遮光,因而可将现有微发光二极管显示面板或量子点显示面板等显示面板中的偏光片取消掉,既不影响显示面板的显示效果,又使得整个显示面板更为纤薄。
本申请实施例还提供的一种显示面板驱动方法,用于对上述的显示面板进行驱动,其中,该方法可以包括步骤100。
本申请实施例中,该方法应用于具有触控显示面板的电子设备,该电子设备可以是手机、平板电脑、笔记本电脑、掌上电脑、车载电子设备、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer,UMPC)、上网本或者个人数字助理(personal digital assistant,PDA)等移动电子设备,也可以是个人计算机(personal computer,PC)、电视机(television,TV)、柜员机或者自助机等非移动电子设备。
步骤100、在息屏状态下,在所述触控驱动电极与所述第一电极之间施加第一电压,以使所述电致变色层由原色变化至目标色,所述原色为黑色或灰色。
上述步骤100中,第一电压为电致变色层中电致变色材料的变色电压。因为在息屏状态下,第一电极无需给显示面板显示画面供电,因而可用于为电致变色层的变色反应提供电场作用,并通过在第二电极及第一电极之间施加使电致变色层进行变色反应的第一电压,使得电致变色层由黑色或灰色的原色状态变化为目标色状态,从而使整个显示面板呈现多彩状态;另外,因为电致变色层在颜色不发生变化的情况下不会再消耗电能,上述多彩图案的呈现方式的功耗远低于现有屏保方式的功耗。
可选地,在一种实施方式中,在电致变色层可由原色经不同的强度的电场作用变化至多种颜色的情况下,上述步骤100具体包括步骤111~113:
步骤111、在息屏状态下,确定目标色;
步骤112、根据所述目标色与电压值之间的对应关系,确定第一电压;
步骤113、在所述第二电极与所述第一电极之间施加所述第一电压,以使所述电致变色层由原色变化至目标色,所述原色为黑色或灰色。
上述步骤111中,目标色为用户预先设置的息屏显示颜色,即在进入息屏状态时,获取用户预先设置的颜色,作为上述目标色。
上述步骤112中,上述对应关系为预先根据电致变色层的电致变色性能确定的电压值与颜色之间的对应关系,表明了电致变色层在变化值至目标色至所需的电压值。因而在确定了目标色后,可以根据上述对应关系,确定目标电压,作为上述第一电压。
上述步骤113中,通过在第二电极与第一电极之间施加第一电压,即可以使得位于第二电极与第一电极之间的电致变色层接受电场作用下进行变色反应,并变化至目标色。
上述实施方式适用于单个电致变色层可通过不同电场作用变化值不同颜色的场景,根据所需变化的目标色与电压值之间的对应关系,在第二电极与第一电极之间施加对应的第一电压,即可以将电致变色层变化至不同的颜色状态。
可选地,在一种实施方式中,上述驱动方法还包括步骤200~300:
步骤200、在接收到亮屏信号的情况下,在所述第二电极与所述第一电极之间持续施加预设时长的第二电压,以使所述电致变色层由所述目标色恢复至所述原色;其中,所述第二电压与所述第一电压大小相等,且方向相反。
上述步骤200中,在接收到亮屏信号的情况下,说明用户需要使用显示面板,但因为此时电致变色层还处于目标色状态,而该目标色一般为彩色状态,为了不影响显示面板的正常显示,需要将电致变色层恢复至黑色或灰色的原色状态,因而在第二电极与第一电极之间持续之间预设时长的第二电压,因为该第二电压与第一电压大小相等且方向相反,即可以将电致变色层从目标色状态恢复至原色状态。
其中,因为电致变色层需要在变色电压下持续作用预设时长才会完成变色反应,因而在控制电致变色层恢复至原色时,需要控制上述第二电压持续预设时长,使得电致变色层可以接收预设时长的第二电压对应的电场作用完成变色反应。上述预设时长由电致变色层中的电致变色材料确定。
在电致变色层恢复至原色后,因为在电致变色层恢复至原色状态的情况下,电致变色层不会影响显示面板的显示,因而第一电极即可以复用为向各子像素单元供电,显示面板进入正常显示状态,避免了在显示面板正常显示时因电致变色层变换至除黑色和灰色外的其他颜色而影响显示效果的问题。
上述实施方式中,在接收到亮屏信号的情况下,先在触控驱动电极与第一电极施加第二电压,使电致变色层恢复至黑色或灰色状态,然后再驱动触控层进入触控感应状态,避免了在显示面板正常显示时因电致变色层显示除黑色和灰色外的其他颜色而影响显示面板的显示效果的问题。
可选地,本申请实施例还提供一种电子设备,包括上述显示面板,处理器,存储器,存储在存储器上并可在所述处理器上运行的程序或指令,该程序或指令被处理器执行时实现上述显示面板驱动方法实施例的各个过程,且能达到相同的技术效果,为避免重复,这里不再赘述。
需要注意的是,本申请实施例中的电子设备包括上述所述的移动电子设备和非移动电子设备。
图5为实现本申请实施例的一种电子设备的硬件结构示意图。
该电子设备500包括但不限于:射频单元5001、网络模块5002、音频输出单元5003、输入单元5004、传感器5005、显示单元5006、用户输入单元5007、接口单元5008、存储器5009、以及处理器5010等部件。

可选地,所述处理器5010,还用于在接收到亮屏信号的情况下,在所述第一电极与所述第二电极之间持续施加预设时长的第二电压,以使所述电致变色层由所述目标色恢复至所述原色;其中,所述第二电压与所述第一电压大小相等,且方向相反。
