这里的陈述仅提供与本申请有关的背景信息，而不必然构成现有技术。随着显示面板在不同工业技术领域中的广泛应用，显示面板的驱动技术得到了快速、长足的发展；在传统技术中，显示面板通常采用多个驱动信号来实现自身的扫描驱动，由于显示面板包括多个像素，通过驱动信号循环控制像素进入工作状态，每一个像素依次接入图像信息，以使显示面板能够呈现完整、动态的图像/视频；显示面板中的不同像素之间相互协同工作，以发出不同色阶的光源，给用户带来良好的视觉体验，因此传统技术通过多个驱动信号能够驱动显示面板中的多个像素处于稳定、正常的工作状态。
由于用户对于画面的视觉体验要求越来越高，传统技术中的显示面板逐渐朝着宽屏、大尺寸方向发展，显示面板中像素的数量也越来越多，那么传统技术中的驱动电路就需要更多的驱动信号来实现像素的扫描驱动过程；显示面板的驱动电路包括更多的电子元器件，该驱动电路的电路结构更为复杂，制造成本更高；因此传统技术中显示面板的驱动电路对于像素的扫描驱动成本较高，该驱动电路的电路结构较为复杂，无法普遍地适用于不同类型的工业产品中。

为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
图1示出了本申请实施例提供的像素驱动电路10的结构，为了便于说明，仅示出了与本申请实施例相关的部分，详述如下：
如图1所示，像素驱动电路10包括多个以阵列排布的亚像素，其中亚像素由数据线D和扫描线G交叉限定，数据线D传输数据信号，扫描线G传输扫描信号，数据信号包括图像数据，扫描信号包括通断控制信息，通过扫描信号能够控制每一个亚像素的导通或者关断，通过数据信号能够驱动相应的亚像素发出相应色阶的光源；因此通过数据信号和扫描信号实现多个亚像素的扫描驱动过程，进而使得多个亚像素协作显示完整的图像/视频，给用户带来良好的视觉体验。
如图1所示，本实施例中的像素驱动电路10包括：在水平方向上呈阵列分布的亚像素组20；每一个亚像素组20包括相邻的两列亚像素以及与相邻的两列亚像素连接的一条数据线D。
在本实施例中，将像素驱动电路10中的各列亚像素划分为多个亚像素组20，在每一个亚像素组20中，相邻的两列亚像素之间设置一条数据线D，亚像素组20中所有的亚像素都与该数据线D连接，通过该数据线D即可向两列亚像素同时提供数据信号，通过该数据信号可使亚像素组20发出正常、稳定的光源；因此本实施例可通过一条数据线D可实现亚像素组20的扫描驱动过程，操作简便。
其中，在水平方向上，N个依次相邻的亚像素组20形成一个像素组30；其中所述N为大于或者等于2的正整数。
作为一种可选的实施方式，本实施例将多个亚像素组20划分为相应的像素组30，进而本实施例中的像素组30包括多列依次相邻的亚像素，通过像素组30能够结合不同列亚像素光源，像素组30能够发出不同颜色的光源，简化了本实施例中像素驱动电路10的扫描驱动步骤。
在本实施例中，在同一个像素组30中，所有的数据线接入同一路数据信号。
如上所述，由于本实施例中的像素组30包括N个依次相邻的亚像素组20，每一个亚像素组20包括一条数据线D；在本实施例中，同一个像素组30中的所有数据线接入同一路数据信号，通过该数据信号能够同时驱动多列亚像素开启充电，以实现像素组30中亚像素的扫描驱动过程，提高了多个亚像素的扫描驱动效率，降低了像素驱动电路10中数据信号的数量；因此本实施例通过更少数量的数据信号实现了多个亚像素的扫描驱动过程，降低了亚像素的扫描驱动成本，简化了像素驱动电路10中数据线D的布线结构；本实施例中的像素驱动电路10更易于实现。
在本实施例中，在同一个像素组30中，位于同一行的任意两个亚像素连接不同的扫描线G。
由于在像素组30的同一行亚像素中，每一个亚像素都对应连接特定的扫描线G，以 接入相应的扫描信号，通过该扫描信号能够控制每一个亚像素的导通或者关断状态；由于本实施例中的任意一个像素组30中，同一行中的多个亚像素由不同的扫描信号进行控制，不同的亚像素能够实现不同的发光效果；因此每一个像素组30在多路扫描信号的驱动下，能够结合不同亚像素的发光状态，以使显示面板能够呈现完整、动态的画面，给用户带来良好的视觉体验，提高了本实施例中像素驱动电路10的可操控性。
因此在本实施例中，同一个像素组的所有数据线D接入同一路数据信号，通过该数据信号能够控制多列亚像素的发光状态；因此本实施例中极大地减少了数据信号的数量，降低了显示面板中多个亚像素的扫描驱动成本；当显示面板中亚像素的数量增加时，本实施例中的像素驱动电路10不必增加数据信号的数量，也可实现对于大规模亚像素的循环扫描过程，简化了像素驱动电路10的电路结构；并且像素组30中亚像素组20的数量可根据实际需要设定，比如N＝2或者N＝3等，那么本实施例中的像素驱动电路10应用在不同数量的亚像素中，以实现对于显示面板中亚像素的扫描驱动过程，因此本实施例中的像素驱动电路10具有极高的兼容性，可扩展性极强，可适用于不同的工业领域中；从而有效地解决了示例性技术中显示面板的扫描驱动电路对于像素的扫描驱动成本较高，电路结构过于复杂，兼容性较低，无法普遍适用的问题。
作为一种可选的实施方式，在上述像素驱动电路10中，每一个亚像素包括像素电极和开关管，参照图1中所示出的像素驱动电路10，开关管的第一导通端接数据线D，开关管的第二导通端接像素电极，开关管的控制端接扫描线G；当扫描线G将扫描信号输出至开关管的控制端时，通过扫描信号的电平状态能够控制开关管的导通或者关断；当通过扫描信号控制开关管导通时，开关管的第一导通端和第二导通端直接连接，数据线通过开关管将数据信号传输至像素电极，以实现所述亚像素的扫描驱动过程，所述亚像素在该数据信号的驱动下实现图像显示效果，显示面板中的画面能够呈现完整、清晰的图像/视频。
作为一种可选的实施方式，任意两个亚像素中的开关管具有相同的电源导通极性。
示例性的，在本实施例提供的像素驱动电路10中，每一个亚像素中的开关管都是NMOS管或者每一个亚像素中的开关管都是PMOS管；示例性的，每一个亚像素中的开关管都是PNP型三极管或者每一个亚像素中的开关管都是NPN型三极管；因此本实施例通过扫描信号和数据信号可同时控制显示面板中多个亚像素的导通或者关断，以使所述像素驱动电路10能够实现扫描驱动功能，显示面板能够结合多个亚像素以呈现更加完整、清晰的画面；从而本实施例中像素驱动电路10具有更高的扫描驱动效率，显示面板中多个亚像素的光源显示状态具有更高的可控性。
作为一种可选的实施方式，在同一个像素组30中，所有数据线D的一端共接形成像 素组30的数据信号输入端。
参照图1所示出像素驱动电路10的结构，在本实施例中，同一个像素组30中的所有数据线D共接于一端，通过像素组30的数据信号输入端可接入一路数据信号，通过该数据信号能够驱动像素组30中的所有亚像素处于稳定的工作状态，操作简便，降低了本实施例中像素驱动电路10中多个亚像素的扫描驱动成本；当像素驱动电路10应用于显示面板时，减少了数据信号的数量，像素驱动电路10具有更为简化的电路布局结构，每一个像素组30在数据信号和扫描信号的驱动下能够呈现不同色阶的混色画面。
为了更好的说明图1中像素驱动电路10在电路结构上的优势，下面将通过一个对比实验来说明本实施例中像素驱动电路10的优势，其中图2示出了一个参考电路结构；其中在图1的像素驱动电路10中，N＝2，图1和图2中的像素驱动电路都各自包含：4行亚像素以及10列亚像素。
根据图1和图2中的电路结构，由于图1中像素驱动电路10中，同一个像素组中所有的数据线D共接于同一路数据信号；因此图1中的像素驱动电路就10只需要接入3路数据信号，即可实现所有亚像素的扫描驱动过程；而图2中的像素驱动电路10需要接入6路数据信号，才能实现所有亚像素的扫描驱动过程；因此对于同样数量的亚像素，图1中的像素驱动电路10比图2中的电路在数据信号的数量上少二分之一；由此可得，本实施例的像素驱动电路10极大地简化了多个亚像素的扫描驱动方式，像素驱动电路10只需要接入数量更少的数据信号，即可实现多个亚像素的扫描驱动过程，并且本实施例中的像素驱动电路10具有更为简化的电路结构，克服了示例性技术中显示面板驱动电路的电路结构复杂的不足之处。
需要说明的是，图2中所示出的参考电路结构仅仅为一示例性电路结构而已，用于对比说明本实施例中像素驱动电路10的技术效果，并非意味着图2中的参考电路结构为本领域的现有技术。
作为一种可选的实施方式，图3示出了本实施例提供的像素驱动电路10的另一种结构，如图3所示，在同一个像素组30中任意相邻两条数据线D，前一条数据线的第二端接后一条数据线的第一端；在像素组30中，第一条数据线的第一端接入数据信号。
在本实施例中，由于在同一个像素组30中，相邻的两条数据线D直接连接，以实现数据信号的相互传递，当像素组30中的第一条数据线的第一端接入数据信号时，像素组30中的每一条数据线D都能够接入该数据信号，进而本实施例通过一路数据信号能够同时驱动像素组30中所有的亚像素进入充电状态，以实现多列亚像素的扫描驱动过程；因此本实施例通过像素驱动电路10中多个数据线D循环绕制的方式，以减少像素驱动电路10中 数据信号的数量，降低了像素驱动电路中多个亚像素的扫描驱动成本，同时也简化了像素驱动电路10中数据线的空间布局结构，本实施例中的像素驱动电路10能够普遍地适用于不同类型的工业产品中。
示例性的，在图3所示出的像素驱动电路10中，N＝3，则每一个像素组30包括3个依次相邻的亚像素组，在每一个像素组30中，所有的3条数据线D都能够接入同一路数据信号，通过该数据信号实现对于像素组30中所有亚像素的扫描驱动过程；相比于图2中所示出的电路结构，图3中的像素驱动电路10中数据信号的数量只有图2中像素驱动电路中数据信号数量的三分之一；由此可得，图3中所示出的像素驱动电路10极大地减少了数据信号的数量，简化了电路结构。
作为一种可选的实施方式，在垂直方向上，任意相邻的两个亚像素具有相同颜色；在水平方向上，任意相邻的两个亚像素具有不相同的颜色。
在本实施例中，同一列亚像素中的所有亚像素具有相同的颜色，进而通过一路数据信号能够控制一列亚像素的发光状态，以使多个亚像素能够协同工作，以显示更加完整、协调的混色画面；同时在水平方向上，通过不同的扫描信号能够控制相应的亚像素发出相应颜色的光源，提高了本实施例中不同亚像素中发光状态的可操作性，进而通过结合多个亚像素能够呈现出不同色阶的画面，给用户带来良好的视觉体验，提高了本实施例中像素驱动电路10的可操控性。
作为一种可选的实施方式，图4示出了本实施例提供的各列亚像素的颜色分布示意，如图4所示，在依次相邻的三列亚像素中，任意两列亚像素的颜色不相同，并且任意一列亚像素的颜色是：红色、绿色以及蓝色中的任意一种。
在本实施例中，像素驱动电路10中任意相邻的三列亚像素能够组合：红色、绿色以及蓝色这三者颜色，以使显示面板中的画面能够呈现色阶更加丰富的图像/视频，在通过扫描信号和数据信号对每一列的亚像素进行扫描驱动过程，不同三列亚像素的颜色能够进行混色以得到更加完整、动态的画面，操作简便，用户的视觉体验更佳。
作为一种可选的实施方式，所述N为3的倍数。
每一个像素组包含多个亚像素组，并且亚像素组中每一个亚像素组中具有两列颜色不相同的亚像素，则本实施例中的像素组至少包含三种基本色(红色、绿色以及蓝色)，在扫描信号和数据信号的扫描驱动下，像素组能够结合这三种基本色以呈现各种色阶的混色画面，以使每一个像素组能够具有色彩更加丰富的画面，显示面板能够结合多个像素组呈现更加完整、清晰的画面，本申请实施例中像素驱动电路10具有较佳的控制响应速度，用户的视觉体验更佳。
作为一种可选的实施方式，任意两个所述亚像素具有相同数量的畴区。
在本申请实施例中，每一个亚像素包括至少一个畴区，每一个亚像素的畴区接收扫描信号和数据信号，以实现相应的充电效果；由于每一个亚像素的畴区数量相同，因此通过扫描信号和数据信号能够同时驱动多个亚像素实现相同的发光效果，显示面板中多个亚像素具有较为相似的扫描驱动性能，相邻亚像素之间的亮度和色彩差异较小，提高了本实施例中像素驱动电路的控制性能，多个亚像素进行混色后能够显示更加协调的完整画面，像素驱动电路具有更加广泛的适用范围。
作为一种可选的实施方式，在同一个像素组30的同一行亚像素中，依次相邻的亚像素在对应的扫描信号的驱动下依次前后开启。
如上所述，由于在同一个像素组30中的同一行亚像素所接的扫描线G完全不相同，进而通过相应的扫描信号能够分别控制同一行亚像素处于不同的工作状态，以改变显示面板中的画面显示效果；在本实施例中，通过扫描信号能够分别控制同一行相邻亚像素依次前后开启，以实现充电功能，保障显示面板中的多个亚像素能够有顺序地发出光源，实现亚像素的扫描驱动过程，显示面板中的亚像素始终能够处于循环稳定的工作状态。
示例性的，以图1中所示出的像素驱动电路10为例，图5示出了本实施例中各条扫描线中扫描信号的波形曲线，如图5所示；其中D1代表第一个像素组30所接入的数据信号的波形曲线，只有当数据信号D1处于高电平时，第一个像素组30中相应的亚像素才能进入充电状态；其中G1代表第一个像素组30中第一条扫描线的波形曲线，G2代表第一个像素组30中第二条扫描线的波形曲线，依次类推，只有当扫描信号处于高电平时，相应的亚像素接入该高电平的扫描信号，才能实现充电操作；因此图5中各个扫描信号的波形曲线，在T1至T6的时间内，相应的扫描信号依次输出高电平，进而驱动第一个像素组30中第一行亚像素依次开启充电，如此反复，实现对于第一个像素组30中所有亚像素的循环扫描过程，显示面板中的多个亚像素在相应扫描信号的驱动下分别进入充电状态，显示面板中的画面能够显示更加完整、清晰的图像/视频。
作为一种可选的实施方式，在同一个像素组30中，任意两个亚像素连接不同的扫描线D。
参照图1所示，通过一路数据信号能够向同一个像素组30中所有的亚像素提供图像数据，并且由于同一个像素组30中每一个亚像素分别接入各自的扫描线，通过相应的扫描信号能够驱动每一个亚像素分别进行充电，并发出相应颜色的光源；在本实施例中，由于同一像素组30中的不同亚像素分别接入不同的扫描信号，同一像素组30中不同亚像素在扫描信号和数据信号的控制下处于不同的工作状态，不同亚像素中的光源相互协同工作， 以发出不同色阶的图像/视频，像素驱动电路10的控制灵活性极高；从而本实施例不但通过不同的扫描线G分别驱动相应的亚像素处于不同的工作状态，以提高显示面板中整体画面的可控性，而且同一个像素组30中所有的亚像素能够接入同一路数据信号，以维持多个亚像素的安全、稳定工作；显示面板中画面给用户带来良好的视觉体验。
作为一种可选的实施方式，在水平方向上，任意相邻的两个亚像素连接不同的扫描线G。
在同一行中任意相邻的两个亚像素具有不同的发光状态，通过不同的扫描信号能够分别控制相邻亚像素的发光状态，相邻的亚像素在相应扫描信号的驱动下能够发出相应色阶的光源，从而本实施例能够结合不同的亚像素发出多种色彩的光源；所述像素驱动电路具有良好的可控性能，提高了用户的使用体验，所述像素驱动电路具有最佳的控制性能。
作为一种可选的实施方式，在上述像素驱动电路10中，任意相邻的两行亚像素之间存在M条扫描线G；其中，所述M为正整数并且满足以下条件：
M＝2*N              (1)
由于同一个像素组30中同一行的任意两个亚像素分别不同的扫描线G；因此本实施例中相邻两行亚像素之间扫描线G的数量满足上式(1)，则同一个像素组30中同一行的每个亚像素分别能够与相应的扫描线G连接，以接入扫描信号，每一个亚像素在相应扫描信号的驱动下处于不同的工作状态，进而本实施例中像素驱动电路10具有合理的布线结构，能够使多个亚像素协作以显示清晰、完整的画面，提高了显示面板中画面的整体协调性。
示例性的，如图1所示，当N＝2，M＝4，则同一个像素组30中相邻两行亚像素之间存在4条扫描线；例如第一行亚像素与第二行亚像素之间存在4条扫描线：G3、G4、G5、G6；在第一个像素组30的第一行亚像素中，第一个亚像素接扫描线G2，第二个亚像素接扫描线G1，第三个亚像素接扫描线G3，第四个亚像素接扫描线G4，依次类推；因此同一个像素组30中同一行的每一个亚像素都与相应的扫描线G连接，以实现亚像素的扫描驱动功能。
作为一种可选的实施方式，任意相邻的两列亚像素之间存在一条数据线D。
参照图1所示出的像素驱动电路10，数据线D在像素驱动电路能够均匀分布，以使显示面板中多个亚像素能够实现扫描驱动功能，数据线D和扫描线G在像素驱动电路10中均匀分布，以使所述像素驱动电路10具有较为简化的空间布局，保障了像素驱动电路10能够处于正常、稳定的工作状态；从而本申请实施例中的像素驱动电路10能够适用于不同的工业领域中，所述像素驱动电路10具有较为简化的电路结构，降低了本申请实施例中像素驱动电路10的制造成本和应用成本。
作为一种可选的实施方式，第一数据线和第二数据线具有不同的电源极性，其中，所述第一数据线和所述第二数据线分别位于相邻的两个所述像素组。
参照图1中所示出的像素驱动电路，每一个像素组中所有的数据线具有相同的电源极性，以实现像素组中多个亚像素的同步扫描驱动过程；本申请实施例相邻像素组分别由不同电源极性的数据信号进行驱动，进而像素组中相应的亚像素能够实现相应的充电功能，每一个像素组中的亚像素发出相应的光源，提高了相邻像素组的光源色彩兼容性能，减少了相邻像素组之间的色阶差异幅值，显示面板能够显示更加清晰、协调的画面，所述像素驱动电路10具有更佳的兼容性能。
作为一种可选的实施方式，任意两个像素组：第一像素组和第二像素组，第一像素组中的第i个亚像素和第二像素组中的第j个亚像素接同一条扫描线G，并且第一像素组中的第i个亚像素和所述第二像素组中的第j个亚像素位于同一行；所述i、j为正整数，并且0<i≤2*N，0<j≤2*N。
参照图1中所示出像素驱动电路10的结构，示例性的，在同一行亚像素中，每一个像素组的第一个亚像素连接同一条扫描线G，每一个像素组的第二个亚像素连接同一条扫描线G，依次类推；因此不同像素组中位于同一行相应的亚像素相应连接至同一条扫描线，通过一路扫描信号能够分别控制多个像素组中相应亚像素的扫描驱动过程，提高了像素驱动电路10中多个像素组的扫描驱动效率，每一个像素组具有良好的可操控性，显示面板能够按照用户的实际需求呈现动态、清晰的画面，本申请实施例中像素驱动电路具有更高的实用价值。
作为一种可选的实施方式，第一个像素组中的第i列亚像素和第二像素组中的第j列亚像素具有相同的颜色。
在本申请实施例中，每一列亚像素能够接入同一路数据信号，同一列亚像素能够发出相应颜色的光源；在同一行亚像素中，第一个像素组中第i列亚像素的亚像素与第二像素组中第j列亚像素的亚像素接入同一路扫描信号，本申请实施例通过同一路扫描信号能够同步控制不同像素组中相同颜色亚像素的发光状态，以使显示面板中不同的亚像素能够呈现色彩更加一致的光源，即降低了像素驱动电路10中不同像素组的扫描驱动成本，又提高了显示面板中多个像素组所呈现画面的颜色协调性，用户的使用体验更佳。
作为一种可选的实施方式，任意两个亚像素具有相同的形状和面积。
在本申请实施例中，每一个亚像素的形状和面积将会影响到相应亚像素的发光状态；由于每一个亚像素具有相同的形状和面积，因此像素驱动电路10中每一个亚像素接入扫描信号和数据信号，每一个亚像素能够呈现完全一致的光源效果，用户通过显示面板能够获 取完整的图像/视频信息；所述像素驱动电路10能够结合多个亚像素以呈现质量更佳的画面，提高了本申请实施例中像素驱动电路10的实用价值。

其中，在水平方向上，N个依次相邻的亚像素组形成一个像素组；其中所述N为大于或者等于2的正整数。
在同一个像素组中，所有的数据线接入同一路数据信号。
在同一个像素组中，位于同一行的任意两个亚像素连接不同的扫描线。
在本实施例中，通过栅极驱动器601能够生成不同电平状态的扫描信号，以控制亚像素的通断状态，源极驱动器602在外界控制信号的控制下能够生成相应的数据信号，当源极驱动器602将数据信号输出至亚像素时，该亚像素根据数据信号显示相应的图像/视频，显示面板能够呈现完整、清晰的画面；因此本实施例结合栅极驱动器601和源极驱动器602使显示面板中的多个亚像素始终处于稳定的工作状态，本实施例中阵列基板60具有较为简化的电路结构，能够普遍地适用于不同类型的显示面板中，适用范围极广。
作为一种可选的实施方式，上述栅极驱动器601和源极驱动器602都可以采用示例性技术中的电路结构来实现，比如，栅极驱动器601可采用示例性技术中的栅极驱动电路来实现，所述栅极驱动电路包括MOS管和充电电容等电子元器件，通过控制MOS管的通断可输出不同电平状态的扫描信号，该扫描信号能够改变各个亚像素的工作状态；又比如，源极驱动器602可采用示例性技术中源极驱动电路来实现，其中所述源极驱动电路包括多个以阵列排布的移位寄存器，当源极驱动电路接入控制信号时，通过控制信号能够控制位寄存器的数据移位功能，以使源极驱动电路生成相应的数据信号，该数据信号包括图像数据，亚像素根据数据信号实现相应的图像/视频显示功能；从而本实施例中的栅极驱动器601和源极驱动器602具有极强的兼容性，易于实现。
像素驱动电路10与栅极驱动器601以及源极驱动器602，栅极驱动器601和源极驱动器602将扫描信号和数据信号输出至像素驱动电路10时，通过扫描信号和数据信号实现像 素驱动电路10的扫描驱动过程，显示面板能够呈现完整的画面；参照上述图1至图5的实施例，由于图6中的像素驱动电路10的多列亚像素可接入同一路数据信号，则本实施例中的源极驱动器602可生成数量更少的数据信号，极大地简化了阵列基板60中的电路布线结构，通过更少的数据信号对像素驱动电路10中的亚像素进行扫描驱动，极大地降低了本实施例中阵列基板60的制造成本和应用成本，阵列基板60的电路结构更加简化，兼容性极强；该阵列基板60能够适用于不同的工业领域中。
图7示出了本实施例提供的显示装置70的结构，如图7所示，显示装置70包括阵列基板60和背光源701，阵列基板60与背光源701电连接，其中所述背光源701能够实现相应的发光效果，通过阵列基板60能够改变背光源701的光源色彩和亮度，以使显示装置70能够呈现不同的画面，保障了显示装置70的正常和稳定工作。
所述阵列基板60包括：栅极驱动器、源极驱动器以及像素驱动电路。

在同一个像素组中，所有的数据线接入同一路数据信号。
在同一个像素组中，位于同一行的任意两个亚像素连接不同的扫描线。
参照图6的实施例，由于在上述阵列基板60将依次相邻的多个亚像素组划分为一个像素组，并且在一个像素组中，所有的数据线D都接入同一路数据信号，进而本实施例中阵列基板60具有更少的数据信号，简化了数据线D在阵列基板60上的空间布局结构，兼容性更强；因此当阵列基板60应用于显示装置70时，极大地降低了显示装置70中各个亚像素的扫描驱动成本，显示装置70在扫描信号和数据信号的驱动下能够呈现完整的画面，给用户带来良好的视觉体验，并且该显示装置70的内部电路结构更加简化，降低了显示装置70的应用成本和制造成本；有效地解决了示例性技术中显示装置70的扫描驱动成本较高，内部电路结构复杂，用户的视觉体验不佳的问题。
在具体应用中，上述显示装置70可以为任意类型的显示装置，例如，LCD(Liquid Crystal Display，液晶显示装置)、OLED(Organic Electroluminesence Display，有机电激光 显示)显示装置、QLED(Quantum Dot Light Emitting Diodes，量子点发光二极管)显示装置或曲面显示装置等。
