 本发明的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
有鉴于需要大量的迹线引出触控电极100至标定空间，为了减少迹线的数量，本实施例提供了一种触控显示面板，如图1所示，该触控显示面板包括一个或者多个触控电极100、第一解复用电路200以及第二解复用电路300。其中，第一解复用电路200包括晶体管T11、晶体管M11、晶体管T12、晶体管M12、晶体管T13、晶体管M13、晶体管T14、晶体管M14、晶体管T15、晶体管M15、晶体管T16以及晶体管M16，从左至右的第一个触控电极100与晶体管T11的源极/漏极中的一个、晶体管M11的源极/漏极中的一个电性连接，晶体管T11的栅极接入控制信号EN11，晶体管M11的栅极接入控制信号SN11，晶体管T11的源极/漏极中的另一个接入触控驱动信号DR11；从左至右的第二个触控电极100与晶体管T12的源极/漏极中的一个、晶体管M12的源极/漏极中的一个电性连接，晶体管T12的栅极接入控制信号EN12，晶体管M12的栅极接入控制信号SN12，晶体管T12的源极/漏极中的另一个接入触控驱动信号DR12；从左至右的第三个触控电极100与晶体管T13的源极/漏极中的一个、晶体管M13的源极/漏极中的一个电性连接，晶体管T13的栅极接入控制信号EN13，晶体管M13的栅极接入控制信号SN13，晶体管T13的源极/漏极中的另一个接入触控驱动信号DR13；从左至右的第四个触控电极100与晶体管T14的源极/漏极中的一个、晶体管M14的源极/漏极中的一个电性连接，晶体管T14的栅极接入控制信号EN14，晶体管M14的栅极接入控制信号SN14，晶体管T14的源极/漏极中的另一个接入触控驱动信号DR14；从左至右的第五个触控电极100与晶体管T15的源极/漏极中的一个、晶体管M15的源极/漏极中的一个电性连接，晶体管T15的栅极接入控制信号EN15，晶体管M15的栅极接入控制信号SN15，晶体管T15的源极/漏极中的另一个接入触控驱动信号DR15；从左至右的第六个触控电极100与晶体管T16的源极/漏极中的一个、晶体管M16的源极/漏极中的一个电性连接，晶体管T16的栅极接入控制信号EN16，晶体管M16的栅极接入控制信号SN16，晶体管T16的源极/漏极中的另一个接入触控驱动信号DR16。
其中，第二解复用电路300包括一个或者多个晶体管，例如，晶体管T31，晶体管T31的源极/漏极中的一个与晶体管M11的源极/漏极中的另一个、晶体管M12的源极/漏极中的另一个、晶体管M13的源极/漏极中的另一个、晶体管M14的源极/漏极中的另一个、晶体管M15的源极/漏极中的另一个以及晶体管M16的源极/漏极中的另一个电性连接。在本实施例中，从六个触控电极100引出的六条迹线经过第一解复用电路200、第二解复用电路300后仅需一条信号线连接至晶体管T31的源极/漏极中的另一个，即可读出该六个触控电极100的触摸信息，极大地减少了延伸至标定空间的迹线数量。
在上述第一解复用电路200和/或第二解复用电路300中，使用了大量的晶体管，而每个晶体管的栅极对应需要一个控制信号，例如，晶体管T11的栅极接入控制信号EN11，晶体管M11的栅极接入控制信号SN11，如图2所示，在时间段T21、时间段T23以及时间段T25中，控制信号EN11为低电位以关闭晶体管T11，控制信号SN11为高电位以打开晶体管M11，以打入触控驱动信号DR11；在时间段T22、时间段T24中，控制信号EN11为高电位以打开晶体管T11，控制信号SN11为低电位以关闭晶体管M11，以感测从左至右的第一个触控电极100。对应地，就需要两条独立的传输线分别传输控制信号EN11、控制信号SN11，这样虽然减少了标定空间中迹线的数量，但是需要增加控制信号的数量以及传输线的数量。
有鉴于增加解复用电路后需要增加对应的控制信号以及传输线的技术问题，本实施例提供一种触控显示面板，如图3所示，该触控显示面板包括基板、触控层以及第一解复用电路200，基板包括显示区AA和非显示区NA；触控层设置在基板的一侧，触控层包括设置在显示区AA的多个触控电极100；第一解复用电路200设置在基板的一侧且对应非显示NA区设置，第一解复用电路200包括与对应的触控电极100电连接的解复用单元，例如，解复用单元210、解复用单元220、解复用单元230、解复用单元240、解复用单元250或者解复用单元260中的至少一个，每个解复用单元包括第一晶体管和第二晶体管，一触控电极100与第一晶体管的源极/漏极中的一个、第二晶体管的源极/漏极中的一个电性连接，且第一晶体管的栅极与第二晶体管的栅极电性连接；其中，第一晶体管或者第二晶体管中的一个打开时，第一晶体管或者第二晶体管中的另一个关闭。
可以理解的是，本实施例提供的触控显示面板，通过在一个解复用单元中配置第一晶体管或者第二晶体管中的一个打开时，第一晶体管或者第二晶体管中的另一个关闭，第一晶体管的栅极与第二晶体管的栅极电性连接，第一晶体管、第二晶体管可以仅通过一个信号实现分时驱动，即信号处于高电位时可以导通第一晶体管/第二晶体管中的一个，信号处于低电位时可以导通第一晶体管/第二晶体管中的另一个，相比于第一晶体管、第二晶体管需要两个信号进行驱动的技术手段，本申请可以减少触控显示面板中解复用电路所需的信号数量，进而可以减少传输这些信号的传输线数量，也减小了边框占用空间。
需要进行说明的是，第一晶体管可以为晶体管T11、晶体管T12、晶体管T13、晶体管T14、晶体管T15或者晶体管T16中的一个，第二晶体管可以为晶体管M11、晶体管M12、晶体管M13、晶体管M14、晶体管M15或者晶体管M16中对应的一个，例如，晶体管T11与晶体管M11对应。
其中，第一晶体管可以但不限于为N沟道型晶体管或者P沟道型晶体管中的一个，第二晶体管为N沟道型晶体管或者P沟道型晶体管中的另一个。
其中，每个解复用单元还包括控制线，一控制线与同一解复用单元中第一晶体管的栅极、第二晶体管的栅极电性连接。
例如，解复用单元210的控制线CL11与晶体管T11的栅极、晶体管M11的栅极电性连接，如此，控制线CL11传输的使能信号EM11即可实现晶体管T11、晶体管M11的分时导通。同理，解复用单元220的控制线CL12与晶体管T12的栅极、晶体管M12的栅极电性连接，如此，控制线CL12传输的使能信号EM12即可实现晶体管T12、晶体管M12的分时导通。解复用单元230的控制线CL13与晶体管T13的栅极、晶体管M13的栅极电性连接，如此，控制线CL13传输的使能信号EM13即可实现晶体管T13、晶体管M13的分时导通。解复用单元240的控制线CL14与晶体管T14的栅极、晶体管M14的栅极电性连接，如此，控制线CL14传输的使能信号EM14即可实现晶体管T14、晶体管M14的分时导通。解复用单元250的控制线CL15与晶体管T15的栅极、晶体管M15的栅极电性连接，如此，控制线CL15传输的使能信号EM15即可实现晶体管T15、晶体管M15的分时导通。解复用单元260的控制线CL16与晶体管T16的栅极、晶体管M16的栅极电性连接，如此，控制线CL16传输的使能信号EM16即可实现晶体管T16、晶体管M16的分时导通。
可以理解的是，在本实施例中，不仅减少第一解复用电路200所需的使能信号的数量至原来的二分之一；同时，与图1所示的触控显示面板相比，本实施例中第一解复用电路200所需的控制线的数量也可以减少至原来的二分之一。
在其中一个实施例中，控制线用于传输使能信号，使能信号打开第一晶体管或者第二晶体管中的一个，且同时关闭第一晶体管或者第二晶体管中的另一个。例如，使能信号具有能够打开N沟道型晶体管的高电位和能够打开P沟道型晶体管的低电位。
可以理解的是，在本实例中，各使能信号可以为方波信号或者脉冲信号，该两者中的任一者均具有两种电位，一种电位为高电位，该高电位可以打开N沟道型晶体管或者关闭P沟道型晶体管；另一种电位为低电位，该低电位可以关闭N沟道型晶体管或者打开P沟道型晶体管。
在其中一个实施例中，触控显示面板还包括设置在基板的一侧且位于非显示区NA的一个或者多个第一焊盘，例如，焊盘PAD1，一第一焊盘与一控制线对应电性连接。第一焊盘的数量与解复用单元的数量或者与控制线的数量相同，或者，第一焊盘的数量小于第一晶体管与第二晶体管的数量之和。可以理解的是，这些第一焊盘用于连接信号源的输出端与对应的控制线，例如，焊盘PAD1与控制线CL11电性连接。在本实施例中，随着控制线的数量减少，对应的第一焊盘的数量也减少了，不论是控制线或者第一焊盘的数量减少，均可以减少显示面板的空间占用，尤其是在显示面板的空间紧凑的情况下，能够节省空间显得更为珍贵。
在其中一个实施例中，在同一第一解复用电路200中，每个第一晶体管的源极/漏极中的另一个相互电性连接，每个第二晶体管的源极/漏极中的另一个用于对应接入不同的触控驱动信号。
例如，如图3所示，晶体管T11的源极/漏极中的另一个、晶体管T12的源极/漏极中的另一个、晶体管T13的源极/漏极中的另一个、晶体管T14的源极/漏极中的另一个、晶体管T15的源极/漏极中的另一个以及晶体管T16的源极/漏极中的另一个依次分别对应接入触控驱动信号DR11、触控驱动信号DR12、触控驱动信号DR13、触控驱动信号DR14、触控驱动信号DR15以及触控驱动信号DR16，如此可以实现每个触控电极100的单独驱动。晶体管M11的源极/漏极中的另一个与晶体管M12的源极/漏极中的另一个、晶体管M13的源极/漏极中的另一个、晶体管M14的源极/漏极中的另一个、晶体管M15的源极/漏极中的另一个以及晶体管M16的源极/漏极中的另一个电性连接，如此可以减少迹线的数量并通过一个传输端感测六个触控电极100。
在其中一个实施例中，在同一第一解复用电路200中，每个第二晶体管的源极/漏极中的另一个相互电性连接，每个第一晶体管的源极/漏极中的另一个用于对应接入不同的触控驱动信号。
例如，晶体管M11的源极/漏极中的另一个、晶体管M12的源极/漏极中的另一个、晶体管M13的源极/漏极中的另一个、晶体管M14的源极/漏极中的另一个、晶体管M15的源极/漏极中的另一个以及晶体管M16的源极/漏极中的另一个依次分别对应接入触控驱动信号DR11、触控驱动信号DR12、触控驱动信号DR13、触控驱动信号DR14、触控驱动信号DR15以及触控驱动信号DR16，如此可以实现每个触控电极100的单独驱动。晶体管T11的源极/漏极中的另一个与晶体管T12的源极/漏极中的另一个、晶体管T13的源极/漏极中的另一个、晶体管T14的源极/漏极中的另一个、晶体管T15的源极/漏极中的另一个以及晶体管T16的源极/漏极中的另一个电性连接，如此可以减少迹线的数量并通过一个传输端感测六个触控电极100。
在其中一个实施例中，触控显示面板还包括第二解复用电路300，第二解复用电路300包括至少一个第三晶体管，一第三晶体管的源极/漏极中的一个与每个第一晶体管的源极/漏极中的另一个或者每个第二晶体管的源极/漏极中的另一个电性连接，至少一个第三晶体管的栅极用于接入不同相位的驱动信号。
需要进行说明的是，第三晶体管可以为晶体管T22，晶体管T22的源极/漏极中的一个可以与晶体管M11的源极/漏极中的另一个、晶体管M12的源极/漏极中的另一个、晶体管M13的源极/漏极中的另一个、晶体管M14的源极/漏极中的另一个、晶体管M15的源极/漏极中的另一个以及晶体管M16的源极/漏极中的另一个电性连接，或者，晶体管T22的源极/漏极中的一个也可以与晶体管T11的源极/漏极中的另一个与晶体管T12的源极/漏极中的另一个、晶体管T13的源极/漏极中的另一个、晶体管T14的源极/漏极中的另一个、晶体管T15的源极/漏极中的另一个以及晶体管T16的源极/漏极中的另一个电性连接，如此，在对应的驱动信号的控制下，可以通过晶体管T22的源极/漏极中的另一个感测六个触控电极100。
需要进行说明的是，第二解复用电路300中的每个第三晶体管对应一个第一解复用电路200。
在其中一个实施例中，触控显示面板还包括第二焊盘，例如，焊盘PAD2，一第二焊盘与一第三晶体管的源极/漏极中的另一个电性连接；且第二焊盘的数量与第一解复用电路200的数量相等，或者，第二焊盘的数量小于同一第一解复用电路200中解复用单元的数量。
可以理解的是，在本实施例中，由于采用了第一解复用电路200、第二解复用电路300，减少了延伸至第二焊盘的迹线数量，同时也减少了第二焊盘的使用数量，能够节省空间。
在其中一个实施例中，触控显示面板还包括触控迹线，例如，触控迹线JL，一触控迹线的一端与一触控电极100连接，一触控迹线的另一端与第一晶体管的源极/漏极中的一个、第二晶体管的源极/漏极中的一个电性连接；且触控迹线、触控电极100位于同一膜层中。
可以理解的是，在本实施例中，同层设置触控迹线、触控电极100可以减少触控显示面板的厚度。
如图3、图4所示，在解复用单元210中，晶体管T11的栅极、晶体管M11的栅极同时接入使能信号EN11，在时间段T21、时间段T23以及时间段T25中，使能信号EN11处于低电位，晶体管T11打开，晶体管M11关闭，此时可以对从左至右的第一个触控电极100打入驱动信号DR11；在时间段T22、时间段T24中，使能信号EN11处于高电位，晶体管T11关闭，晶体管M11打开，此时可以感测从左至右的第一个触控电极100。
在其中一个实施例中，本实施例提供一种显示装置，其包括上述至少一实施例中的触控显示面板。
可以理解的是，本实施例提供的显示装置，通过在一个解复用单元中配置第一晶体管或者第二晶体管中的一个打开时，第一晶体管或者第二晶体管中的另一个关闭，第一晶体管的栅极与第二晶体管的栅极电性连接，第一晶体管、第二晶体管可以仅通过一个信号实现分时驱动，即信号处于高电位时可以导通第一晶体管/第二晶体管中的一个，信号处于低电位时可以导通第一晶体管/第二晶体管中的另一个，相比于第一晶体管、第二晶体管需要两个信号进行驱动的技术手段，本申请可以减少触控显示面板中解复用电路所需的信号数量，进而可以减少传输这些信号的传输线数量，也减小了边框占用空间。
