具体实施方式
为了使得本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属 领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
如上所述，目前，微流控芯片具有提前设计好液滴运动的路径，所以设计完成之后，微流控驱动电路只能针对已有的路径进行驱动处理。
本公开的至少一个实施例提供了一种微流控装置、用于微流控装置的操作方法以及一种控制装置，可以实现通过触控面板来控制微流控芯片，以对待检测液体进行操作，由此操作方式更灵活、功能更丰富。
图1是根据本公开至少一个实施例的微流控装置的示意性结构框图。如图1所示，根据本公开至少一个实施例的微流控装置100包括触摸面板110、微流控芯片120和控制装置130。
触摸面板110用于检测触摸面板110的触摸面上的接触动作，这些接触动作可以包括点击、双击、长触、滑动等。触摸面板110根据触摸面板110的触摸面上的接触动作可生成检测信号。检测信号可包括表示接触动作在触摸面板110上的位置信息的信号、表示接触动作在触摸面板110上的按压强度信息的信号、表示接触动作在触摸面板110上的持续时长信息的信号等。上述的位置信息例如可包括接触动作在触摸面板110上的坐标信息。
触摸面板110例如可以包括但不限于电阻式触摸面板、红外式触摸面板、表面声波式触摸面板、电容式触摸面板，本公开的实施例对此不作限制。
在一些实施例中，触摸面板110的检测区与微流控芯片120的操作区域相对应，例如在触摸面板110与微流控芯片120重叠的情况下，触摸面板110的检测区在微流控芯片120上的投影大于或等于微流控芯片120的操作区域，以使得用户对透过触摸面板110看到的微流控芯片120的操作均能够被检测到；又例如，在微流控装置100还包括用于显示微流控芯片120的图像的显 示面板且该显示面板与触摸面板110重叠的情况下，触摸面板110的检测区在该显示面板上的投影大于或等于显示在该显示面板上的微流控芯片120的操作区域，以使得用户对透过触摸面板110看到的微流控芯片120的操作均能够被检测到。例如，在图1所示的微流控装置100中，触摸面板110可与微流控芯片120上下重叠，触摸面板110在朝向用户一侧，以使得用户可以进行触摸操作，具体地，触摸面板110的检测区可覆盖微流控芯片120的操作区域，从而与微流控芯片120的操作区域相重叠。触摸面板110的检测区至少可以是部分透明的，使得位于触摸面板110背侧的微流控芯片120的操作区域可见，从而用户能够直观观察和控制目标液滴的运动。例如，触摸面板110的检测区可具有不同程度的透射率，例如100％、90％、80％、70％、60％、50％、40％、30％、20％、10％、或5％的透射率，本公开的实施例对此不作限制。
图2是根据本公开至少一个实施例的触摸面板的结构示意图。如图2所示，触摸面板110为电容式触摸面板，该电容式触摸面板为互电容型，包括衬底111、多个第一电极条112、多个第二电极条113、第二信号线114和第一信号线115。衬底111包括检测区1111和位于检测区1111周围的引线区1112；多个第一电极条112并列设置于检测区1111的衬底111上，每个第一电极条112包括多个间隔设置的第一子电极；多个第二电极条113并列设置于检测区1111的衬底111上，每个第二电极条113包括多个间隔设置的第二子电极，并且，第二电极条113所在的延伸线和第一电极条112所在的延伸线彼此交叉设置；第一信号线115与第一电极条112对应连接，第二信号线114与第二电极条113对应连接。第一电极条112和第二电极条113位于检测区内，而第二信号线114和第一信号线115位于引线区1112内。
在触摸面板中，第一子电极和第二子电极中的一方可以为驱动电极，另一方可以为感应电极。第一子电极和与其交叉的第二子电极之间可以在交叉位置形成感应电容，由此，多个第一子电极和多个第二子电极彼此交叉，在检测区内得到感应电容的阵列，用于检测触控操作。外物(例如手指等)靠近某一感应电容所在处，则会改变相应区域的第一子电极和第二子电极之间的感应电容的电容量。通过第二信号线114和第一信号线115检测电容量发生变化的相应感应电容的位置，可以定位触点。
第一信号线115和第二信号线114可以汇聚至端口区域B处，以便于通 过例如柔性电路板与外界的控制单元例如控制装置等电连接。
例如，衬底111可以为单独的透明基板，例如玻璃基板、塑料基板等，也可以复用例如微流控芯片120的表面层，例如微流控芯片120的保护盖板(例如，玻璃基板、塑料基板等)或封装层等。第一电极条112和第二电极条113可以通过例如透明导电材料(例如ITO)制备；第一电极条112和第二电极条113可以位于衬底111上的不同层中，由至少一个绝缘层间隔开，由此实现沿不同方向延伸并彼此交叉，或者第一电极条112和第二电极条113可以位于衬底111上的相同层中，但是在彼此交叉的位置通过桥接方式实现交叉而绝缘。第二信号线114和第一信号线115例如可以通过铝或铝合金、铜或铜合金等制备。
应理解，图2示出的触摸面板110仅为示例性的，本公开的实施例对比不作限制。
微流控芯片120用于根据检测到的接触动作对目标液滴执行预设操作，其中，该目标液滴在微流控芯片120上或在微流控芯片120中。预设操作可包括但不限于使目标液滴移动、使目标液滴分离、使目标液滴聚合、对目标液滴施加电压、对目标液滴加热等，本公开的实施例对此不作限制。
图3是根据本公开至少一个实施例的微流控芯片的俯视图，图4是沿图3中的线L-L’的剖视图。如图3所示，微流控芯片120包括由虚线框示出的操作区域1221，操作区域1221包括驱动阵列，驱动阵列包括阵列分布的多个驱动单元1222，每个驱动单元1222配置为在电信号的控制下对液滴进行操作。
如图4所示，驱动单元1222位于衬底基板401上。驱动单元1222可直接形成在衬底基板401上，也可制备为独立器件然后通过绑定(bonding)的方式结合到衬底基板401上。衬底基板401同样可以为玻璃基板、塑料基板等。
例如，微流控芯片120可以采用无源驱动方式或有源驱动方式，本公开的实施例对此不作限制。下面本文就以有源驱动方式为例进行说明。
对于有源驱动方式，例如，每个驱动单元1222可包括开关元件和与该开关元件电连接的驱动电极409。驱动电极409在施加有电压的情况下对液滴进行操作。每个开关元件用于向一个或多个驱动电极409提供驱动信号。例如，开关元件与驱动电极409一一对应。作为示例，在图4中，开关元件以薄膜晶体管的形式示出，然而本领域技术人员可理解开关元件还可实施为其他形 式，例如场效应晶体管，本公开的实施例对此不作限制。驱动电极409例如可通过金属(例如合金)、掺杂的半导体材料(例如多晶硅)、氧化物导电材料(例如氧化铟锡(ITO)、氧化铟锡(IZO))等任何合适的材料形成，然而本公开的实施例对此不作限制。
如图4所示，以薄膜晶体管为例的开关元件可包括栅极402、栅绝缘层403、有源层404、第一极405和第二极406。作为示例，在本公开的一些实施例中，第一极405为源电极以及第二极406为漏电极，然而在其他实施例中，第一极405也可以是漏电极，第二极406也可以是源电极，本公开的实施例对此不作限制。驱动电极409与该薄膜晶体管之间形成有绝缘层或介电层407。驱动电极409通过绝缘层407中的通孔408与第二极406电接触，以接收来自第二极406的电信号。
如图4所示，微流控芯片120还可包括疏水层411，疏水层411形成在微流控芯片120的用于承载液滴的表面上。通过疏水层411可防止液滴渗透进微流控芯片120内部，减少液滴的损耗，并有助于液滴在微流控芯片120上移动。疏水层411位于驱动电极409远离衬底基板401的表面之上。疏水层411可增大表面张力梯度，从而有助于在微流控芯片120上的液滴的移动。疏水层411可以直接形成在驱动电极409的表面上，或者在疏水层411与驱动电极409之间还可形成有绝缘层410，由此可以使得驱动电极409与液滴电绝缘。该绝缘层410还可以起到平坦层的作用，以使得微流控芯片120具有平坦的表面。在一些示例性实施例中，疏水层411可通过特氟龙(teflon)、
Figure PCTCN2020079596-appb-000001
(perfluoro(1-butenylvinylether)polymer)等材料形成，绝缘层410可通过无机绝缘材料或有机绝缘材料形成，例如通过树脂形成，然而本公开的实施例对此不作限制。
此外，微流控芯片120还可包括控制器、栅极驱动电路和数据驱动电路。控制器与栅极驱动电路和数据驱动电路耦接，接收输入信号并且根据输入信号为栅极驱动电路和数据驱动电路提供时序信号、驱动信号等，以控制栅极驱动电路和数据驱动电路同步工作。栅极驱动电路可以通过栅线向驱动阵列例如逐行施加扫描信号，以控制开关元件的开启或截止，数据驱动电路可以通过数据线向驱动阵列施加驱动信号。每个驱动单元1222的开关元件的栅极与该驱动单元所在行对应的栅线电连接，开关元件的第一极405与该驱动单元所在列的数据线电连接，从而与数据驱动电路电连接以接收驱动信号，因 此可以在开关元件开启时向驱动电极409提供驱动信号。微流控芯片120还可包括端口部分，该端口部分通过例如柔性电路板与外部信号连接，以接收输入信号(控制信号)，并将该输入信号提供该微流控芯片120的控制器，以产生用于栅极驱动电路和数据驱动电路的相应信号。
应理解，图3和图4示出的微流控芯片120仅为示例性的，本公开的实施例对比不作限制。
在本公开的至少一个实施例中，微流控装置100还可包括控制装置130。控制装置130与触摸面板110和微流控芯片120信号连接，以根据触摸面板110提供的检测信号生成用于控制微流控芯片120的控制信号，以对目标液滴执行预设操作。
如图5所示，控制装置130可包括：第一接口1311、控制器1312和第二接口1313。第一接口1311配置为与触摸面板110信号连接，第二接口1313配置为与微流控芯片120信号连接，控制器1312配置为获取触摸面板110对触摸面板110的触摸面上的接触动作的检测结果，控制微流控芯片120根据检测结果对目标液滴执行预设操作。例如第一接口1311可通过例如柔性电路板与图2所示的触摸面板110的端口区域B电连接，以接收触摸信号；第二接口1313可通过例如柔性电路板与微流控芯片120的端口区域电连接，以发送微流控芯片120所需的输入信号，由此可以向微流控芯片120的驱动阵列中相应的驱动单元的开关元件的第一极405提供驱动信号，即可以向该驱动单元的驱动电极409提供驱动信号，从而对液滴进行与触摸信号对应的驱动操作。
