Micro LED产品是用来进行彩色显示的装置，该装置包含阵列分布的多个Micro LED晶粒，各Micro LED晶粒都包含红色、绿色、蓝色的子像素。在对上述装置驱动时，一般采用无源阵列驱动方式控制各晶粒中的子像素发光。在驱动过程中，对显示阵列水平向逐行扫描，并在各行被选中的过程中，通过向对应的子像素传输显示数据对应的电信号，从而控制各子像素发光。
LED显示阵列的驱动装置的电路结构如图1所示，该驱动装置包括扫描驱动器20和数据驱动器10，扫描驱动器20和数据驱动器10分别与显示器30电连接。
显示器30中包括呈阵列分布的Micro LED晶粒，各Micro LED晶粒的输出端和扫描驱动器20电连接，各Micro LED晶粒的输入端和数据驱动器10电连接。扫描驱动器20设有多个驱动信号输出端，同一行的Micro LED晶粒的输出端与同一驱动信号输出端电连接。数据驱动器10设有多个显示信号输 出端，同一列的Micro LED晶粒的输入端与同一列显示信号输出端电连接。
在显示器30显示过程中，扫描驱动器20向各驱动信号输出端依次输出行导通信号以选中对应行的Micro LED晶粒，同时，数据驱动器10向被选中行中各Micro LED晶粒传输显示数据对应的电信号，该行的Micro LED晶粒中有导通电流信号通过时，该行中各Micro LED晶粒分别发出导通电流信号对应的光强。
更具体地，各Micro LED晶粒都包含红色、绿色、蓝色的子像素，各行中相同颜色子像素由扫描驱动器20生成的同一行选通信号控制。下面以一行Micro LED晶粒为例，对LED的驱动过程进行解释。
LED显示阵列的驱动装置的电路结构图如图2所示，显示器30包括显示单元31，显示单元31包括红色显示子单元32、绿色显示子单元33和蓝色显示子单元34。其中，红色显示子单元32中包含该行Micro LED晶粒中的多个红色子像素LEDR，绿色显示子单元33中包含该行Micro LED晶粒中的多个绿色子像素LEDG，蓝色显示子单元34中包含该行Micro LED晶粒中的多个蓝色子像素LEDB。
扫描驱动器20包括驱动单元21，驱动单元21包括红色行驱动器211、绿色行驱动器212和蓝色行驱动器213。在一些实施例中，上述行驱动器为晶体管。
在一些实施例中，数据驱动器可以为供电单元11，该供电单元11中包括红色电流源IR、蓝色电流源IG、绿色电流源IB，红色电流源IR的输入电压值为VR，绿色电流源IG的输入电压值为VG，蓝色电流源IB的输入电压值为VB，上述各电流源用于向对应的子像素传输显示数据对应的电信号。其中，各电流源的电压值是由与电流源的输入端电连接的外围电路确定的。
在一应用场景中，当Micro LED晶粒中各子像素的显示顺序为：红色子像素、绿色子像素、蓝色子像素时，针对一行Micro LED晶粒的显示过程，驱动单元21先控制红色行驱动器211导通，红色显示子单元32的输出端电压调整为低电平，此时，供电单元11中三个电流源均向对应的显示子单元输出电源信号，红色显示子单元32中各红色子像素的输入端获得对应的电信号，红色子像素导通，发出对应的红光。由于绿色行驱动器212和蓝色行驱动器213未导通，即使绿色显示子单元33和蓝色显示子单元34的输入端获得电信号，也不会发光。值得注意的是，图2所示的电流源输出的电信号与对应的显示子单元中各子像素呈一一对应关系，例如：红色显示子单元32中包含5个红色子像素，则红色电流源IR输出的一组电信号中包含5个电信号。
在红色显示子单元32显示预设时间长度之后，红色行驱动器211断开，绿色行驱动器212导通，绿色显示子单元33产生预设时间长度的光，然后绿色行驱动器212断开，蓝色行驱动器213导通，蓝色显示子单元34产生预设时间长度的光，从而完成一行显示子单元的显示。当各显示子单元的显示频率足够快时，人眼可看到三组显示子单元同时发光。
由于驱动单元中的晶体管存在漏电流，因此，即使晶体管未导通，该晶体管与对应的显示子单元与电流源之间存在漏电流，且电流源保持供电状态，该电流源存在对应的电压值，因此会产生对应的供电损耗。
为了解决上述问题，本申请实施例提供一种驱动装置、驱动系统及显示设备，用以解决驱动装置在驱动过程中供电损耗高的技术问题。本申请的技术构思是：一驱动装置包括数据编组单元、供电单元和驱动单元，数据编组单元通过对各帧显示数据进行拆分，从每帧显示数据中获得多帧显示子数据，驱动单元根据获得的多帧显示子数据，生成对应的行选通信号，并利用该行选通信号控制各帧显示子数据依次进行显示，此外，数据编组单元利用多帧显示子数据生成对应的行选通控制信号，以使供电单元根据该行选通控制信号依次生成各帧显示子数据在显示过程中所需的电源信号，对于显示单元当前无需显示的其他帧显示子数据，供电单元不提供对应的电源信号，使得显示其他帧显示子数据对应的器件在未获得行选通信号时不产生能量损耗，从而降低驱动装置在驱动过程中的供电损耗。

在拆分完成多帧显示子数据之后，数据编组单元402还用于：
将各帧显示子数据依次发送至驱动单元401，即，将上述拆分获得的各颜色通道对应的显示子数据： 红色显示子数据、蓝色显示子数据和绿色显示子数据，依次发送至驱动单元401。

电源控制单元01设有至少一个输出端，电源生成单元02设有至少一个使能端，输出端和使能端一一对应电连接。

更具体地，当显示单元31显示一帧画面时，会先显示一个颜色通道对应的显示子数据，当该显示子数据分区域依次显示的时候，每个显示区域对应一个供电电源和一组行选通信号，即电源生成单元02内包括多个该颜色通道对应的电源生成子单元，该颜色通道对应的电源生成子单元的数量和改颜色通道对应的显示区域的数量相同，各电源生成子单元和各显示区域一一对应。驱动单元401内包括多个驱动子单元，驱动子单元的数量和显示区域的数量相同。电源控制单元01生成各电源生成子单元对应的使能信号，使得该电源生成子单元输出该显示区域所需的电源信号。驱动子单元生成并输出该显示区域所需的一组行选通信号，该组行选通信号用于将该显示区域所有行的、该颜色通道对应的子像素依次选中。当显示单元31中所有显示区域将该颜色通道对应的显示子数据显示完成后，电源生成单元02才会生成其他颜色通道对应的显示子数据所需的电源信号，电源控制单元01才会生成该电源信号所需的使能信号，驱动单元401才会生成其他颜色通道对应的显示子数据所需的行选通信号。
更具体地，显示单元31针对一帧显示数据的显示过程如图5所示，当显示单元31中各子像素的显示顺序为：红色子像素、绿色子像素、蓝色子像素时，红色电源控制子单元4311包括多个控制子单元：第一红色电源控制子单元、……、第N红色电源控制子单元，红色电源控制子单元4311根据第一红色显示子单元301对应的行选通控制信号生成并输出第一红色使能子信号，红色电源生成子单元4321根据该红色使能子信号生成并向红色显示子单元发送红色电源子信号。其中，红色电源生成子单元4321包括多个生成单元：第一红色电源生成子单元、……、第N红色电源生成子单元，红色电源控制子单元4311的使能端输出第一红色使能信号，第一红色电源生成子单元生成并向第一红色显示子单元301发送红色电源子信号，驱动单元401向第一红色显示子单元311发送第一组行选通信号，以控制第一红色显示子单元301显示对应的图像。待第一红色显示子单元301显示完成后，第二红色电源生成子单元在第二红色电源控制子单元生成的第二红色使能信号的驱动下生成并向第二红色显示子单元发送红色电源子信号，驱动单元401向第二红色显示子单元发送第二组行选通信号，以控制第二红色显示子单元显示对应的图像，直至第N红色显示子单元显示完成对应的图像，至此，从该帧显示数据中获得的红色显示子数据全部显示完成。
绿色电源控制子单元4312再生成绿色使能子信号，以使绿色电源生成单元022生成并依次向各绿色显示子单元发送绿色电源子信号。驱动单元401按照显示顺序，依次向第一绿色显示子单元302至第N绿色显示子单元305发送行选通信号，以使各绿色显示子单元依次显示对应的图像。
待该帧显示数据中获得的绿色显示子数据全部显示完成后，蓝色电源控制子单元4313再生成蓝色 使能子信号，以使蓝色电源生成单元023生成并依次向各蓝色显示子单元发送蓝色电源子信号。驱动单元401按照显示顺序，依次向第一蓝色显示子单元303至第N蓝色显示子单元306发送行选通信号，以使各蓝色显示子单元依次显示对应的图像。
至此，显示单元31将一帧显示数据全部显示完成，可按照上述描述的显示顺序显示下一帧显示数据直至驱动装置40不再接收显示数据。
在上述实施例中，数据编组单元通过将各帧显示数据拆分成红色显示子数据、蓝色显示子数据和绿色显示子数据，数据编组单元根据上述拆分的三帧显示子数据依次生成对应的行选通控制信号，电源控制单元按照行选通控制信号对应的使能信号，以使电源生成单元根据使能信号生成各帧显示子数据对应的电源信号，由于该电源信号是按照各帧显示数据的显示而对应切换的，电源信号的切换频率不高，降低了供电器件的要求。
在图5所示的显示过程中，供电单元403所需要的行选通控制信号是数据编组单元402根据各帧显示子数据生成的。更具体地，
当显示子数据对应的电信号的电压等级和供电单元所需的行选通控制信号的电压等级不一致时，数据编组单元402通过电平转换，将显示子数据转换为行选通控制信号；
当显示子数据对应的电信号的电压等级和供电单元所需的行选通控制信号的电压等级一致时，数据编组单元402将显示数据确定为行选通控制信号。当显示数据对应的电信号的电压等级和供电单元所需的行选通控制信号的电压等级一致时，数据编组单元402将显示数据确定为行选通控制信号，从而简化了电路结构，降低电路成本。
此外，数据编组单元402还可以利用场同步信号实现行选通控制信号。即数据编组单元402获得场同步信号，并在拆分一帧显示子数据时，将显示子数据对应的场同步信号确定为对应的行选通控制信号，在拆分完成一帧显示子数据后，调整场同步信号的信号值，并将信号值确定为下一帧显示子数据对应的行选通控制信号的信号值。在一些实施例中，可以通过累加器调整场同步信号的信号值。场同步信号的应用不再使数据编组单元402依照各显示子数据中的各像素生成对应的行选通控制信号，且场同步信号易于获得，简化了数据编组单元402的处理流程，降低了对驱动装置40的性能要求。
在图5所示的显示过程中，驱动单元401所需要的显示子数据是数据编组单元402生成的。在一些实施例中，数据编组单元402的数据输出速率和驱动单元401的数据接收速率匹配时，数据编组单元402可通过堆栈的方式存储生成的空间域数据，并按照预设进出栈规则向驱动单元发送各显示子数据，该预设进出栈规则为先进先出规则。
驱动单元401获得显示子数据之后，驱动单元401根据显示子数据生成行选通控制信号，并根据该行选通控制信号生成对应的行选通信号。在一些实施例中，驱动单元401包括多个晶体管，各晶体管包括栅极、源极和漏极。驱动单元401中晶体管的栅极未获得行选通控制信号时，漏极和源极之间不导通，与漏极连接的显示单元31中的一行子像素的输出端无法接地，该子像素无法导通电流，不能发光；驱动单元401中晶体管的栅极获得行选通控制信号时，漏极和源极之间导通，与漏极连接的显示单元31中的一行子像素的输出端接地，该子像素可导通电流，晶体管的漏极输出的接地信号为行选通信号，在子像素的输入端接收到电信号时，该子像素发光。
在另一些实施例中，数据编组单元402的数据输出速率和驱动单元401的数据接收速率不匹配时，在数据编组单元402中设有双倍速率同步动态随机(Double Data Rate，简称：DDR)存储器，数据编组单元402将各帧显示子数据储存至双倍速率同步动态随机存储器，并按照驱动单元401的数据接收速率，从双倍速率同步动态随机存储器中读取各帧显示子数据，将各帧显示子数据发送至驱动单元。
在上述实施例中，当驱动单元接收数据的速率与数据编组单元获取数据的速率不匹配时，驱动单元与数据编组单元在进行信息传输时易产生传输错误，通过在数据编组单元中设置双倍速率同步动态随机存储器，对数据编组单元获得显示数据后，拆分获得的多帧显示子数据进行储存，再按照驱动单元接收数据的速率进行数据传输，以规避数据传输错误；同时，双倍速率同步动态随机存储器的设置也保障了数据编组单元在按照时间顺序接收各帧显示数据后，对各帧显示数据按照颜色通道进行显示子数据的拆分，从而保障了驱动单元能够按照空间域驱动显示单元依次显示各帧显示子数据。
图6为本申请实施例提供的显示设备的电路结构图，如图6所示，显示设备80包括驱动系统70和显示单元31，驱动系统70和显示单元31电连接。
驱动系统70包括一主控器500、一时序控制器600和驱动装置40，主控器500与时序控制器600电连接，时序控制器600和驱动装置40电连接。
主控器500用于向时序控制器600传输原始显示数据；
时序控制器600用于向驱动装置40依次传输原始显示数据对应的多帧显示数据。更具体地，时序控制器600用于将原始显示数据转化为驱动装置40所能处理的显示数据，再将各帧显示数据传输至驱动装置40。
驱动装置40获得多帧显示数据之后的处理过程已在上述过程中进行描述，此处不再赘述。
除了上述实施例，本申请实施例还提供另外一些关于显示设备、驱动系统、驱动装置的实施例，具体如下：
为了解决驱动装置在驱动过程中供电损耗高的技术问题。以下本申请实施例主要包括：一驱动装置包括：电源控制单元、供电单元和区块控制单元，驱动装置在对显示单元组中一显示单元驱动显示时，区块控制单元获得该显示单元各颜色通道对应的行选通控制信号，根据该行选通控制信号生成行选通信号，以使区块控制单元选中显示单元中的待显示颜色通道中的目标行，电源控制单元也获得该行选通控制信号，并利用该信号生成目标行所处的颜色通道对应的使能信号，供电单元在使能信号有效的情况下生成该待显示颜色通道对应的电源信号，显示单元中的目标行在同时获得行选通信号和电源信号的情况下，显示对应的显示数据，显示单元中的其他颜色通道对应的电源控制单元生成的使能信号无效，供电单元也不提供对应的电源信号，使得显示单元中其他颜色通道在不发光时不产生能量损耗，从而降低驱动装置在驱动过程中的供电损耗。
下面对本申请提出的驱动装置所处的应用场景进行解释，如图7所示，显示设备80包括一显示单元组50和一驱动系统70，显示单元组50与驱动系统70电连接。其中，驱动系统70包括一控制器60和多个驱动装置40，显示单元组50可拆分为多个显示单元51，各显示单元51和各驱动装置40一一对应地电连接，各驱动装置40与控制器60电连接。
更具体地，各显示单元51包括呈阵列分布的像素，各像素中包含各颜色通道对应的发光二极管，各显示单元51显示该显示单元组50待显示数据中的一部分显示子数据对应的彩色画面，即所有显示单元51在其对应的驱动装置40的驱动下共同显示控制器待显示的整场画面。在各显示单元51显示的过程中，驱动装置40会按照其接收的行选通控制信号向各颜色通道对应的发光二极管的正极提供电源信号，以驱动发光二极管发光。例如：显示单元组50的像素为3840×2160，将显示单元组50拆分成10行10列的显示单元后，各显示单元的像素为384×216，各像素中包含一红色发光二极管、一蓝色发光二极管和一绿色发光二极管，显示单元51需要对一场画面中红通道的4行显示数据显示时，在一种情况下，驱动装置40根据获得的行选通控制信号向显示单元51同时输出4个行选通信号，以选中上述4行红色发光二极管，驱动装置40同时输出上述4行对应的电源信号，以使4行红色发光二极管同时发光，在另一种情况下，驱动装置40根据获得的行选通控制信号的获取顺序依次向显示单元51输出一行选通信号，以依次选中对应行的红色发光二极管，驱动装置40同时输出备选行的电源信号，以控制上述4行红色发光二极管依次发光。
基于上述应用场景，下面对本申请提出的驱动装置进行详细解释。图8为本申请实施例提供的驱动装置的电路结构图。如图8所示，本申请提供的驱动装置40与一显示单元51电连接，驱动装置40包括区块控制单元41、电源控制单元42和供电单元43，显示单元51包括多颜色通道对应的显示通道。
更具体地，电源控制单元42和供电单元43电连接，供电单元43和一显示单元51电连接，区块控制单元41也与该显示单元51电连接。
电源控制单元42具体用于：
获取显示单元51中各颜色通道对应的行选通控制信号，根据行选通控制信号生成各颜色通道对应的使能信号。更具体地，在驱动装置对应的显示单元51中，目标颜色通道对应的显示通道待显示时，电源控制单元42获得该目标颜色通道对应的有效的行选通控制信号，并根据该行选通控制信号生成对应的使能信号。
供电单元43具体用于：
在使能信号有效时生成电源信号。即在显示单元51中的目标颜色通道对应的显示通道待显示的时候，供电单元43获得有效的使能信号，并输出该目标颜色通道待显示的显示数据对应的电源信号。
区块控制单元41具体用于：
获取行选通控制信号，根据行选通控制信号生成行选通信号。在显示单元51中包含呈阵列分布的像素时，该行选通信号用于在显示单元51中的目标行像素显示的时候选中该行像素。
区块控制单元41获得的行选通控制信号和电源控制单元42获得的行选通控制信号相同。
每一显示单元51根据电源信号和行选通信号显示对应的显示数据。更具体地，每一显示单元51在获得行选通信号和该行选通信号作用行对应的电源信号时，显示对应的显示数据。
在上述实施例中，电源控制单元仅针对显示单元中待显示的显示通道生成对应有效的使能信号，以使供电单元输出电源信号驱动上述像素显示，针对无需显示的其他颜色通道对应的显示通道，电源控制单元产生的使能信号无效，供电单元不输出电源信号，使得驱动颜色通道对应的显示通道显示的器件在像素不发光时不产生能量损耗，从而降低驱动装置在驱动过程中的供电损耗。
驱动装置40的电路结构及驱动装置40与显示单元51的具体连接关系如图9所示。
显示单元51中包括呈阵列分布的像素511，各像素511包括各颜色通道对应的发光二极管。更具 体地，各像素511中包括红色发光二极管R、绿色发光二极管G和蓝色发光二极管B。
对应地，在供电单元43中，包括多个供电子单元，多个供电子单元与一显示单元51电连接。供电单元43中供电子单元的个数和像素511中发光二极管的个数相同。更具体地，各供电子单元与显示单元51中各颜色通道一一对应，即供电单元43中包括红色供电子单元431、绿色供电子单元432和蓝色供电子单元433。
各供电子单元设有多个供电信号输出端，各供电子单元的多个供电信号输出端分别和各像素中一颜色通道对应的发光二极管的正极电连接。以图5所示的显示单元51中像素分布状况为例，包括N行M列像素，显示单元51中每行像素包括M个一颜色通道对应的发光二极管，例如：M个红色发光二极管。
在一些实施例中，M个红色发光二极管的正极连接于一点之后与红色供电子单元431的一输出端电连接，即一行红色发光二极管的正极获得同一电源信号；在另一些实施例中，M个红色发光二极管的正极与红色供电子单元431的M个输出端电连接，即一行红色发光二极管的正极获得的电源信号可存在不同的电源信号。在红色发光二极管的负极获得低电平的行选通信号时，该行M个红色发光二极管根据其正极获得的电源信号的电平信号确定发光状态，即正极电源信号为高电平时发光，正极电源信号为低电平时不发光。蓝色发光二极管和绿色发光二极管的电路连接关系与红色发光二极管的电路连接关系相似，此处不再赘述。图9中为了方便绘制，利用一总线替代。
各供电子单元还设有一使能端和显示信号输入端，电源控制单元42设有多个输出端，显示信号输入端和控制器60电连接，使能端和电源控制单元中一输出端电连接。更具体地，供电子单元用于获取控制器60传输的显示数据，并在使能端接收的使能信号有效时，根据显示数据产生对应的电源信号。其中，显示数据对应的值越大，电源信号中电流信号越强。
各供电子单元获得的使能信号是从与其对应连接的电源控制子单元中获取的。更具体地，电源控制单元42包括多个电源控制子单元，电源控制单元42中电源控制子单元的个数和像素中发光二极管的个数相同。电源控制单元42包括：红色电源控制子单元421、绿色电源控制子单元422和蓝色电源控制子单元423。各电源控制子单元设有多个信号输入端和一输出端，信号输入端和控制器60电连接，该信号输入端用于获取控制器60传输的显示单元51中一颜色通道对应的行选通控制信号，各电源控制子单元根据行选通控制信号生成该颜色通道对应的使能信号。即一电源控制子单元在显示单元51待显示时，获得控制器60发送的多个行选通控制信号，其中，待显示数据对应的行选通控制信号有效，电源控制子单元根据该至少一个有效的行选通控制信号生成有效的使能信号，并将该使能信号传送至对应的供电子单元。更具体地，红色电源控制子单元421获得控制器60发送的红色行选通控制信号时，根据该红色行选通控制信号生成对应的红色使能信号，并将该红色使能信号传输至红色供电子单元431；绿色电源控制子单元422获得控制器60发送的绿色行选通控制信号时，根据该绿色行选通控制信号生成对应的绿色使能信号，并将该绿色使能信号传输至绿色供电子单元432；蓝色电源控制子单元423获得控制器60发送的蓝色行选通控制信号时，根据该蓝色行选通控制信号生成对应的蓝色使能信号，并将该蓝色使能信号传输至蓝色供电子单元433。
在一些实施例中，该电源控制单元为数据译码器，当电源控制单元获得的行选通控制信号存在扰动信号或者数据调制的情况，需要电源控制单元进行对应的去除扰动或者数据解码操作。在另一些实施例中，该电源控制单元为或门，因此，即使一颜色通道对应的显示通道中仅有一行发光二极管待显示，该显示通道对应得电源控制子单元生成的使能信号也是有效的。
其中，行选通控制信号是控制器60根据显示数据对应生成的。当显示数据对应的电信号的电压等级和电源控制单元42所需的行选通控制信号的电压等级不一致时，控制器60通过电平转换，将显示数据转换为行选通控制信号；当显示数据对应的电信号的电压等级和电源控制单元42所需的行选通控制信号的电压等级一致时，控制器60将显示数据确定为行选通控制信号。当显示数据对应的电信号的电压等级和供电单元所需的行选通控制信号的电压等级一致时，数据编组单元402将显示数据确定为行选通控制信号，从而简化了电路结构，降低电路成本。
在各电源控制子单元生成使能信号之后，与电源控制子单元对应连接的供电子单元根据上述使能信号生成对应的电源信号，并将该电源信号传输至显示单元51中各像素中对应的发光二极管的正极。
此外，区块控制单元41中包括多个晶体管集合：红色晶体管集合411、绿色晶体管集合412和蓝色晶体管集合413，各晶体管集合中包含多个晶体管，各晶体管的漏极和每行像素中一发光二极管的负极电连接，各晶体管的源极接地，各晶体管的栅极和控制器电连接，其中，一晶体管与一行中同一颜色通道对应的发光二极管的负极电连接，即红色晶体管集合411中，各红色晶体管一一对应地与各行像素511中的红色发光二极管的负极电连接；绿色晶体管集合412中，各绿色晶体管一一对应地与各行像素511中的绿色发光二极管的负极电连接；蓝色晶体管集合413中，各蓝色晶体管一一对应地与各行像素511中的蓝色发光二极管的负极电连接。晶体管用于根据栅极获取的控制器60发送的行选通控制信号调整晶体管的导通状态，并在晶体管导通时输出行选通信号，发光二极管在获得行选通信号时，其正极 获得电源信号，该发光二极管发光。
在显示单元51中包括N行M列像素的情况下，在一些实施例中，区块控制单元41包括N个红色晶体管、N个绿色晶体管和N个蓝色晶体管，以红色发光二极管与红色晶体管为例，对两者的电路连接关系进行解释：一行M个红色发光二极管的负极电连接于一点后，与一红色发光二极管的漏极电连接，当红色发光二极管的源漏极导通时，该行所有的红色发光二极管的负极均为低电平，在其正极获得高电平的电源信号时，各发光二极管发光。在另一些实施例中，区块控制单元41包括N×M个红色晶体管、N×M个绿色晶体管和N×M个蓝色晶体管，以红色发光二极管与红色晶体管为例，对两者的电路连接关系进行解释：M个红色发光二极管的漏极一一对应地与M个红色发光二极管的负极电连接，M个红色发光二极管获得的行选通控制信号中包含M个行选通控制子信号，各子信号一一对应地传输至对应的红色发光二极管的栅极，在栅极获得的行选通控制子信号有效时，该行选通控制子信号对应的红色晶体管的源漏极之间导通，对应的红色发光二极管的负极为低电平，在其正极为高电平时，该红色发光二极管发光。其中，行选通控制信号中一行选通控制子信号有效时，该行选通控制信号有效。
下面将对驱动装置40对显示单元51的驱动过程进行详细解释。
控制器60获得时序的显示数据，控制器60按照时间顺序将该显示数据传输至驱动装置40中的供电单元43，同时，控制器60根据显示数据生成对应的行选通控制信号，并将该行选通控制信号发送至电源控制单元42中的各电源控制子单元，以及区块控制单元41中的各晶体管中。
一方面，电源控制单元42对获得的行选通控制信号进行筛选，以使各电源控制子单元获得其所需的一颜色通道对应的行选通控制信号，即红色电源控制子单元421获得红色行选通控制信号，绿色电源控制子单元422获得绿色行选通控制信号，蓝色电源控制子单元423获得蓝色行选通控制信号。另一方面，区块控制单元41中各晶体管对行选通控制信号进行筛选，获得对应的行选通控制信号。
若控制器60传输的显示数据中，数据的时序为：RGBRGB，则一像素511中发光二极管的发光顺序为：红色发光二极管R、绿色发光二极管G、蓝色发光二极管B，则电源控制单元42接收的行选通控制信号的顺序为：红色行选通控制信号、绿色行选通控制信号和蓝色行选通控制信号，电源控制单元42可按照数据发送频率控制对应的电源控制子单元接收对应的行选通控制信号：红色行选通控制信号、绿色行选通控制信号、蓝色行选通控制信号。各电源控制子单元生成的使能信号依次为：红色使能信号、绿色使能信号和蓝色使能信号，在各颜色通道的使能信号到达对应的供电子单元时，各供电子单元还分别获得控制器60发送的所需颜色通道的显示数据，从而生成对应的电源信号，依次加在各像素511中红色发光二极管R、绿色发光二极管G和蓝色发光二极管B的正极上，同时，区块控制单元41中各颜色通道对应的晶体管也按照上述顺序依次获得各行选通控制信号，以生成对应的行选通信号，该信号的生成顺序为：红色行选通信号、绿色行选通信号和蓝色行选通信号。
显示单元51中各像素511中的各发光二极管的正负极获得信号，发光二极管导通，产生对应的光强。即像素511中红色发光二极管R的正极接收到红色供电子电源431生成的红色电源信号，同时，该红色发光二极管R的负极收到红色晶体管发出的行选通信号，红色发光二极管导通，发出对应的红色光；绿色发光二极管G和蓝色发光二极管的发光过程与红色发光二极管R的发光过程相同，此处不再赘述。
其中，在一显示单元51中，显示单元包括N行M列像素，各电源控制子单元被配置为按照各颜色通道的显示顺序获取其对应颜色通道关联的n个行选通控制信号，并根据n个行选通控制信号生成颜色通道对应的使能信号；其中，N、M为正整数，n为自然数，n≤N。在一些实施例中，N为1。
当显示单元对n行显示子数据同时显示时，电源控制子单元被配置为同时获取n个行选通控制信号，并根据n个行选通控制信号生成颜色通道对应的一使能信号；
与电源控制子单元电连接的供电子单元被配置为在使能信号有效时生成颜色通道对应的电源信号；
显示单元被配置为在同一时刻获取一颜色通道对应的n个行选通信号及颜色通道对应的电源信号时，显示n行显示数据。
当显示单元对n行显示子数据依次显示时，电源控制子单元被配置为依次获取n个行选通控制信号，并根据各行选通控制信号依次生成颜色通道对应的n个使能信号；
与电源控制子单元电连接的供电子单元被配置为在各使能信号有效时生成颜色通道对应的电源信号；
显示单元被配置为依次获取一颜色通道对应的一行选通信号及颜色通道对应的电源信号时，逐行显示各行显示数据。
在上述相关技术中，显示单元组中各显示单元对应的驱动装置根据行选通控制信号来确定对应生成的使能信号是否有效，从而确定供电单元是否需要生成电源信号，以使显示单元仅在需要显示的时候才会获取电源信号，降低了供电损耗。
图7为本申请实施例提供的显示设备的电路结构图。如图7所示，控制器60设有显示数据输出端 和行选通控制信号输出端，行选通控制信号输出端和各驱动装置40的信号输入端电连接，行选通控制信号和各驱动装置40内晶体管的栅极电连接，显示数据输出端和各驱动装置40的显示信号输入端电连接。
控制器60用于逐次向各驱动装置40输出行选通控制信号和显示数据，以控制各驱动装置根据行选通控制信号和显示信号逐次生成行选通信号。更具体地，控制器60控制各显示单元51逐个点亮，直至将显示单元组50中所有显示单元51全部点亮。
显示单元组50包含多行显示单元51。各驱动装置40与各显示单元51一一对应地电连接。控制器50用于逐行向显示单元中每行显示单元51对应的驱动装置输出行选通控制信号和显示数据，以控制每行显示单元51对应的驱动装置40在获得行选通控制信号和显示数据时，根据行选通控制信号和显示信号同时生成行选通信号。
更具体地，驱动系统70在对多行显示单元进行驱动时，当相邻两个显示单元的亮度相差很大的时候，例如，一显示单元亮度最高，一显示单元亮度最低。若进行逐个显示单元显示，在人眼视觉上，会觉得显示单元所在的区域亮度降低而不会区分两个显示单元的亮度差别，因此，驱动系统70控制处于一行的显示单元一起点亮，并按照各行显示单元的顺序，依行点亮，以提高人眼可视性。
在上述实施例中，控制器将各行显示单元作为一组，对显示单元组中多组显示单元进行点亮，以实现显示单元组中逐行显示单元的点亮，降低了显示过程中相邻区块亮度差别太大产生的串扰现象。
为了方便解释，已经结合具体的实施方式进行了上述说明。但是，上述示例性的讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导，可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用，从而使得本领域技术人员更好的使用所述实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
