具体实施方式
下面将结合本公开一些实施例中的附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的一些实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的一些实施例中，除非另有说明，“多个”是指两个或多于两个。“第一”以及“第二”是对功能和作用基本相同的相同项或相似项进行区分，且本领域技术人员应当理解的是，“第一”和“第二”并不对数量和执行次序进行限定，也并不限定一定不同。
显示装置中的显示面板通过逐帧显示图像在多个帧周期(显示一帧画面的时间)中形成连续的视频画面。相关技术中，在每个帧周期中，通常利用行扫描电路对整个显示面板中的所有亚像素进行逐行扫描，以实现一帧画面的显示。基于此，整个显示面板中所有亚像素显示的帧率一致，通常为60Hz～240Hz。
对于电视机显示、电脑屏幕显示等常见的平面显示而言，显示装置中显示画面的帧率达到60Hz左右，人眼即可观察到非常流畅的显示画面；当帧率高于60Hz之后，人眼不容易察觉到画面有明显的流畅度提升。对于AR(增强现实，Augmented Reality)显示、VR(虚拟现实，Virtual Reality)显示而言，显示帧率则需要达到90Hz才能实现流畅显示；当帧率达到几百赫兹时，AR显示、VR显示会达到比较理想的效果。对于旋转显示等立体显示而言，由于立体画面的显示需要依次快速显示若干幅图像以形成立体图像，因此其显示装置所显示的画面需要具有特别高的帧率(例如几千赫兹或上万赫兹)，才能流畅显示所需的画面。
请参阅图1，本公开的一些实施例提供了一种显示装置1000，包括显示面板100和栅极驱动电路20。
显示面板100具有显示区110和非显示区120。本公开实施例中提及的显 示区110为显示面板100中用于显示的区域，在显示区110的外围，不用于显示的区域则为非显示区120。显示面板100的显示区110包括至少两个子显示区10(例如图1中的显示面板100的显示区110包括a×b个子显示区10)，所述至少两个子显示区10中的每个子显示区10包括多个亚像素11。
栅极驱动电路20包括与所述至少两个子显示区10一一对应的至少两个栅极驱动子电路21(例如图1中所示的a×b个栅极驱动子电路21)，所述至少两个栅极驱动子电路21中的每个栅极驱动子电路21与对应的子显示区10所包括的多个亚像素11电连接。每个栅极驱动子电路21被配置为接收一组第一控制信号，生成一组栅极驱动信号，并将该组栅极驱动信号输出至对应的子显示区10所包括的多个亚像素11。
基于此，显示面板100中不同的子显示区10中的亚像素11数量相同或不同，均可。示例性的，请参阅图2，所述至少两个子显示区10中，各子显示区10所包括的多个亚像素11的数量相同；或者，请参阅图3和图4，所述至少两个子显示区10中，各子显示区10所包括的多个亚像素11的数量不同。
可选的，在各子显示区10所包括的多个亚像素11的数量相同的情况下，请参阅图2，每个子显示区10所包括的多个亚像素11呈矩阵式布置，各子显示区10所包括的多个亚像素11排列成的行数相等，且列数相等。
显示面板100中各个子显示区10的布置方式可以有多种。示例性的，请参阅图2和图3，显示面板100中的多个子显示区10呈矩阵式布置；或者，请参阅图4，多个子显示区10根据显示需要划分为任意形状。
本公开一些实施例对各个子显示区10的布置方式、每个子显示区10中亚像素11的数量以及每个子显示区10的形状等不做限定，实施时根据实际显示需要对各子显示区10进行划分即可。
本公开的一些实施例将显示面板100的显示区110划分为至少两个子显示区10，对于每个子显示区10，通过一个栅极驱动子电路21驱动对应的子显示区10，从而对每个子显示区10输入独立的栅极驱动信号，实现对显示面板100的分区驱动，进而可以实现在一个帧周期中对不同子显示区10中的亚 像素11同步进行扫描。也就是说，每个栅极驱动子电路21仅需实现对对应的子显示区10中的多个亚像素11的扫描，而无需对整个显示面板100中的各亚像素11进行扫描，因此每个栅极驱动子电路21完成对对应的子显示区10中的多个亚像素11的扫描的时间更短；在多个栅极驱动子电路21同时对对应的子显示区10中的多个亚像素11进行扫描的情况下，可以大大减少对整个显示面板100中所有亚像素11完成一次扫描的时间，也即大大缩短了帧周期，从而显著提高了显示画面的帧率，使显示画面的帧率可以达到超高帧率，进而使显示的画面清晰度、流畅度更高，不会出现拖尾、留影等现象。
此处，超高帧率是指帧率大于或等于90Hz，例如90Hz、120Hz、240Hz、300Hz、500Hz、1000Hz、3000Hz、5000Hz、8000Hz、10000Hz或20000Hz等。
另外，本公开的一些实施例能够实现对每个子显示区10的独立驱动，即，通过调整每个子显示区10对应的一组栅极驱动信号的时序等参数，以使不同的子显示区10显示不同帧率的画面，并且还能够使不同的子显示区10之间实现异步扫描刷新。例如，可以根据用户的观看需求和对显示画面的关注度，将显示画面划分为主观看区画面和副观看区画面，其中，将显示主观看区画面的各子显示区10划归为主观看区，将显示副观看区画面的各子显示区10划归为副观看区。通过对每个子显示区10进行独立驱动，可以使主观看区中的各子显示区10显示帧率较高的画面，并使副观看区中的各子显示区10显示帧率较低的画面，相比于整个显示面板100中所有子显示区10均显示高帧率画面的方式，能够有效降低源信号的数据量，从而在不影响用户观看体验的情况下，有效降低数据传输的整体带宽。
请参阅图1，在一些实施例中，显示面板100还包括与至少两个子显示区10一一对应的至少两组栅线60，所述至少两组栅线60中的每组栅线60与对应的子显示区10所包括的多个亚像素11电连接；每个栅极驱动子电路21与对应的子显示区10对应的一组栅线60电连接。以图1中编号为a的子显示区10为例，与子显示区a对应的一组栅线60如图所示，与子显示区a对应的 栅极驱动子电路为栅极驱动子电路a，该栅极驱动子电路a通过该组栅线60与子显示区a中的各个亚像素11连接。
显示装置1000中的栅极驱动电路20的设置方式可以有多种。示例性的，栅极驱动电路20可以单独设置，例如栅极驱动电路20为栅极驱动芯片(Gate IC)或者为GOA(Gate Driver on Array，阵列基板行驱动)电路。示例性的，栅极驱动电路20还可以集成在显示装置的驱动芯片中。只要栅极驱动电路20可以通过其中的各栅极驱动子电路21对每个子显示区10输入独立的栅极驱动信号，实现对各子显示区10的分区控制即可。本公开一些实施例对此不作限定。

示例性的，请参阅图7所示的显示装置1000，该显示装置1000包括驱动芯片50。栅极驱动电路20和源极驱动电路30均集成在驱动芯片50中。显示面板100包括子显示区c、子显示区d、子显示区e和子显示区f四个子显示区10。驱动芯片50还包括与四个子显示区10一一对应的驱动端口51c、驱动端口51d、驱动端口51e和驱动端口51f，以及与四个子显示区10一一对应的数据端口52c、数据端口52d、数据端口52e和数据端口52f。源极驱动电路30通过驱动端口51c与一组数据线70c电连接，该组数据线70c与子显示区c中的各个亚像素11电连接；栅极驱动子电路21c通过驱动端口51c与一组栅线60c电连接，该组栅线60c与子显示区c中的各个亚像素11电连接。类似的，源极驱动电路30通过驱动端口51d与一组数据线70d电连接，该组数据线70d与子显示区d中的各个亚像素11电连接；栅极驱动子电路21d通过驱动端口51d与一组栅线60d电连接，该组栅线60d与子显示区d中的各 个亚像素11电连接。源极驱动电路30通过驱动端口51e与一组数据线70e电连接，该组数据线70e与子显示区e中的各个亚像素11电连接；栅极驱动子电路21e通过驱动端口51e与一组栅线60e电连接，该组栅线60e与子显示区e中的各个亚像素11电连接。源极驱动电路30通过驱动端口51f与一组数据线70f电连接，该组数据线70f与子显示区f中的各个亚像素11电连接；栅极驱动子电路21f通过驱动端口51f与一组栅线60f电连接，该组栅线60f与子显示区f中的各个亚像素11电连接。
需要说明的是，图7中仅以黑色线条示意性表示出四组栅线60和四组数据线70，实际上，每组栅线60中包括一条或多条栅线，每组数据线70中包括一条或多条数据线。另外，图7中仅示出了子显示区c、d、e、f的范围，并未示出每个子显示区10内所包括的各亚像素11以及每组栅线60、每组数据线70与对应的子显示区10内的各亚像素11的连接关系。对于上述未示出的部分，请参阅图5、图6、图8或图9中对应的结构以及描述。
在本公开一些实施例中，每个子显示区10中各亚像素11与对应的一组栅线60、一组数据线70的连接关系可以有多种，只要能通过对应的一组栅线和对应的一组数据线向该子显示区10中的各亚像素11传输所需的信号即可，本公开一些实施例对此不做限定。
请参阅图8，在一些实施例中，每个子显示区10包括多行以及多列亚像素11。在显示面板100包括与所述至少两个子显示区10一一对应的至少两组栅线60及至少两组数据线70的情况下，对于每个子显示区10，该子显示区10对应的一组栅线60所包括的栅线的条数与该子显示区10所包括的亚像素11的行数相等，该子显示区10对应的一组栅线60的各条栅线与该子显示区10所包括的各行亚像素11一一对应电连接；该子显示区10对应的一组数据线70所包括的数据线的条数与该子显示区10所包括的亚像素11的列数相等，该子显示区10对应的一组数据线70的各条数据线与该子显示区10所包括的各列亚像素11一一对应电连接。
以图8中所示的一个子显示区10为例，该子显示区10包括2行3列共6 个亚像素11，与该子显示区10对应的栅极驱动子电路21以及源极驱动电路30如图所示。栅极驱动子电路21通过一组栅线60与6个亚像素11电连接，其中，该组栅线60包括第一栅线61和第二栅线62共两条栅线。第一栅线61与子显示区10中的第一行亚像素电连接，栅极驱动子电路21通过第一栅线61向第一行亚像素输入对应的栅极驱动信号。第二栅线62与子显示区10中的第二行亚像素电连接，栅极驱动子电路21通过第二栅线62向第二行亚像素输入对应的栅极驱动信号。由于每行亚像素分别与不同的栅线电连接，因此可以通过控制第一栅线61和第二栅线62输出的栅极驱动信号的时序，实现对该子显示区10内的各亚像素11的逐行扫描驱动。源极驱动电路30通过一组数据线70与6个亚像素11电连接，其中，从左至右，该组数据线70包括第一数据线71、第二数据线72和第三数据线73共三条栅线。第一数据线71与子显示区10中的第一列亚像素电连接，源极驱动电路30通过第一数据线71向第一列亚像素输入对应的第二数据信号。第二数据线72与子显示区10中的第二列亚像素电连接，源极驱动电路30通过第二数据线72向第二列亚像素输入对应的第二数据信号。第三数据线73与子显示区10中的第三列亚像素电连接，源极驱动电路30通过第三数据线73向第三列亚像素输入对应的第二数据信号。
此处，每个子显示区10对应的一组栅线60所包括的栅线的条数与该子显示区10所包括的亚像素11的行数相等，且该子显示区10对应的一组栅线60的各条栅线与该子显示区10所包括的各行亚像素11一一对应电连接，从而能够通过控制栅极驱动子电路21输出的一组栅极驱动信号的时序，实现对每个子显示区10中各亚像素11的逐行扫描驱动。在此情况下，该子显示区10对应的一组数据线70所包括的数据线的条数与该子显示区10所包括的亚像素11的列数相等，且该子显示区10对应的一组数据线70的各条数据线与该子显示区10所包括的各列亚像素11一一对应电连接，在实现显示功能的同时，有利于减少每个子显示区10对应的数据线的数量，进而简化显示装置1000中的布线。
请参阅图9，在一些实施例中，在显示面板100包括与至少两个子显示区10一一对应的至少两组栅线60及至少两组数据线70的情况下，对于每个子显示区10，该子显示区10对应的一组栅线60包括一条栅线，该子显示区10对应的一条栅线与该子显示区10所包括的多个亚像素11电连接；该子显示区10对应的一组数据线70所包括的数据线的条数与该子显示区10所包括的亚像素11的个数相等，该子显示区10对应的一组数据线70的各条数据线与该子显示区10所包括的多个亚像素11一一对应电连接。
以图9中所示的一个子显示区10为例，该子显示区10包括2行3列共6个亚像素11，与该子显示区10对应的栅极驱动子电路21以及源极驱动电路30如图所示。栅极驱动子电路21通过一组栅线60与6个亚像素11电连接，其中，该组栅线60包括一条第三栅线63，该第三栅线63与子显示区10中的所有亚像素11电连接。栅极驱动子电路21通过第三栅线63向各亚像素11输入对应的栅极驱动信号，从而实现对该子显示区10中所有亚像素11的同时驱动。源极驱动电路30通过一组数据线70与6个亚像素11电连接，其中，该组数据线70包括第四数据线74、第五数据线75、第六数据线76、第七数据线77、第八数据线78和第九数据线79共6条数据线，该6条数据线一一对应地与6个亚像素11电连接，源极驱动电路30通过6条数据线分别向6个亚像素11输入对应的第二数据信号。
此处，每个子显示区10中的各亚像素11均与同一条栅线电连接，且每个亚像素11均与一条数据线单独电连接，从而能够实现对每个子显示区10中各亚像素11的同时驱动，有利于减小每个子显示区10中每帧画面的刷新时间，提高帧率。
请参阅图10，在一些实施例中，显示装置1000还包括与栅极驱动电路20和源极驱动电路30电连接的时序控制器40。此处，时序控制器40例如为独立设置(如图10所示)，或者，时序控制器40集成在驱动芯片50中，本公开的一些实施例对比不做限制。
时序控制器40被配置为接收源信号，根据源信号，生成至少两组第一控 制信号、至少两组第二控制信号和至少两组第一数据信号，并将所述至少两组第一控制信号输出至栅极驱动电路20，将所述至少两组第二控制信号和所述至少两组第一数据信号输出至源极驱动电路30。
下面以图10中所示的显示装置1000为例，详细介绍一下本公开一些实施例中信号处理的原理。请参阅图10，显示面板100的显示区110包括呈矩阵式布置的编号1～a×b的共a×b个子显示区10。每个子显示区10内包括m行n列亚像素，即每个子显示区10的分辨率为m×n(例如图10中每个子显示区10的分辨率为2×3)。
图11为源信号输入时序控制器40的时序信号图，源信号中至少包括表征时序与显示数据的信号，其中，表征时序的信号包括帧率信号、行时钟信号以及列时钟信号等诸多类型的时序信号，不同类型的时序信号编码不同。图11中仅以输入的帧信号为例进行说明，但本公开并不限于此。对于源信号，图11中抽象性的以一条表征时序的信号线以及一条表征显示数据的信号线示出，但实际的源信号编码中，信号种类较多，且表征时序的信号也可以内置于表征显示数据的信号编码中，本公开一些实施例对此不做限定。
请参阅图11，输入的帧信号中，两个相邻的脉冲之间所经过的时间为一个帧周期。在每个帧周期中，源信号中表征显示数据的信号按照一定时序输入时序控制器40。该表征显示数据的信号中包括与图10中a×b个子显示区10所需显示的画面依次对应的显示数据信号。示例性的，如图11所示，信号组1为与子显示区1对应的显示数据信号，信号组a为与子显示区a对应的显示数据信号，信号组a×b为与子显示区a×b对应的显示数据信号，以此类推；按照对应于子显示区编号从1至a×b的顺序，依次向时序控制器40输入每个子显示区10对应的显示数据信号。
时序控制器40对上述输入的信号进行存储，并按照一定时序读取各个子显示区10对应的显示数据信号，然后对上述各显示数据信号进行排列和转化，生成与a×b个子显示区10分别对应的a×b组第一控制信号、a×b组第二控制信号和a×b组第一数据信号，并向栅极驱动电路20中的a×b个栅极驱动子 电路21一一对应地输出上述a×b组第一控制信号。可选的，在栅极驱动子电路21为GOA电路的情况下，输入任一栅极驱动子电路21的一组第一控制信号中包括一组时钟信号(CLK信号组)，该组时钟信号中包括一个或多个控制GOA电路所需的时钟信号，该组时钟信号被配置为控制其对应的子显示区10中各行亚像素11打开的顺序与时间。
时序控制器40还向源极驱动电路30中输出上述a×b组第二控制信号和a×b组第一数据信号。第二控制信号中例如包括时序控制信号，第一数据信号例如为与各子显示区10所显示画面相关的数据信号。
源极驱动电路30接收上述a×b组第二控制信号和a×b组第一数据信号后，根据a×b组第二控制信号，对所接收的a×b组第一数据信号进行转换，例如对各组第一数据信号进行信号选择、信号排列、数模转换、存储等处理，形成a×b组第二数据信号。然后，将a×b组第二数据信号按照一定时序输出至对应的子显示区10中。示例性的，请参阅图12，图12为与图11相对应的多组第二数据信号输出至各子显示区10的理论原理图。图12中，数据组1为与子显示区1对应的一组第二数据信号，数据组a为与子显示区a对应的一组第二数据信号，数据组a×b为与子显示区a×b对应的一组第二数据信号，以此类推。源极驱动电路30将上述几组第二数据线号一一对应地输出至对应地子显示区10中，输出的每组第二数据信号例如包括驱动电流信号或驱动电压信号。
a×b个子显示区中每个子显示区10的分辨率为m×n，在每个子显示区10的帧率相同的情况下，每个子显示区10对应的输出帧信号同步(如图12所示)，源极驱动电路30每帧输出分辨率为(m×a×b)×n。在源极驱动电路30集成在驱动芯片50中的情况下，每个数据端口52的输出分辨率为m×n。
在每个子显示区10的帧率不同的情况下，每个子显示区10对应的输出帧信号异步。示例性的，在每个子显示区10的帧率不同的情况下，源信号中表征显示数据的信号可以按照一种时序或帧频输入时序控制器40，然后按照 另一种时序或帧频将多组第二数据信号从时序控制器40输出。不同子显示区10对应的行有效时间、列有效时间可以不同，从而使不同的子显示区10显示不同帧率的画面。
本公开一些实施例中的显示装置1000例如为OLED显示装置、Mini LED显示装置、Micro LED显示装置、LCD显示装置、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件，本公开一些实施例对此不做限定。
上述任一实施例中的显示装置1000，可以应用于AR显示、VR显示或旋转显示等应用场景中。其中，在一些示例中，旋转显示装置1000的基础模型请参阅图13～图15。旋转显示装置包括旋转轴200(参阅图15)和显示面板100，显示面板100绕着旋转轴200快速旋转，在形成具有一定直径和高度的圆柱体三维显示空间(参阅图13)的同时，能在不同空间位置上按顺序显示多幅二维点阵图像。
旋转显示装置的显示面板100包括按行列方式等间距排列的多个亚像素11。为清晰起见，图13中放大了各亚像素11的尺寸和相邻间距。显示面板100围绕旋转轴200旋转显示的过程中，由于人眼的视觉暂留效应，分散在空间中的所有亚像素11都会被对应看成是在它们被显示时“驻留”在空间中的体素(voxel，三维空间中构成三维图像的最小组成要素)，并且，同一行不同列的多个亚像素11所对应形成的多个体素12分布在高度相同但半径不同的圆上，同一列不同行的多个亚像素11所对应形成的多个体素12分布在半径相同但高度不同的圆上，它们共同构成一个三维体素点阵。
显示面板100围绕旋转轴200旋转显示的过程中，对于任一亚像素11在某单位时间内划过的弧长L，与旋转轴200的垂直距离越远的亚像素11，其划过的弧长L越大。因此，三维体素点阵中的体素12在与旋转轴200平行的方向上疏密一致，而在与旋转轴200垂直的方向上疏密不一，且呈现出内密外疏的分布特点，也即，沿垂直且远离旋转轴200的方向，体素12越来越稀疏。在这种情况下，如果显示面板100中的所有亚像素11显示的画面帧率同 步，观看到的画面则会呈现出内亮外暗的效果(参阅图14)，无法实现体素均匀化，影响用户的观看体验。
基于此，本公开的一些实施例提供的显示装置1000还包括旋转轴200，显示面板100被配置为可围绕旋转轴200旋转。
此处，参阅图15，旋转轴200可以设置于显示面板100的边缘，显示面板100围绕旋转轴200旋转(参阅图15中箭头所示方向)；或者，参阅图16，旋转轴200还可以设置于显示面板100的中轴线处，显示面板100围绕旋转轴200旋转(参阅图16中箭头所示方向)。本公开的一些实施例对此不做限定。
显示面板100具有至少两个亮度调节区130，至少两个亮度调节区130中每个亮度调节区130的长度方向平行于旋转轴200，且至少两个亮度调节区130沿垂直于旋转轴200的方向并列布置；每个亮度调节区130包括至少一个子显示区10。示例性的，请参阅图15，显示装置1000包括显示面板100，以及设置于显示面板100边缘的旋转轴200。显示面板100中包括131、132、133共3个亮度调节区130，每个亮度调节区130的长度方向平行于旋转轴200，且3个亮度调节区130沿垂直于旋转轴200的方向并列布置。每个亮度调节区130中均包括3个子显示区10。
旋转显示装置的源极驱动电路30还被配置为，根据预设的每个亮度调节区130的亮度参数，对拟输出至对应的亮度调节区130的各子显示区10的各组第二数据信号分别进行调整，以使所述至少两个亮度调节区130的平均显示亮度相同或者大致相同；其中，沿垂直于旋转轴200且逐渐远离旋转轴200的方向，各亮度调节区130的亮度参数依次增大。此处，显示亮度是指人眼看到的显示画面的整体亮度；任一亮度调节区130的平均显示亮度，是指人眼看到的该亮度调节区130内显示的画面的整体亮度。
根据显示装置的类型的不同，亮度参数可以有多种。示例性的，在显示装置1000为OLED显示装置、Mini LED显示装置或Micro LED显示装置等电流驱动型显示装置的情况下，亮度参数例如为目标亮度调节区130中各子 显示区10对应的各组第二数据信号中每个第二数据信号的占空比系数。在显示装置1000为LCD显示装置等电压驱动型显示装置的情况下，亮度参数例如为目标亮度调节区130中各子显示区10对应的各组第二数据信号中每个第二数据信号的灰度系数。
本公开一些实施例将显示面板100划分为不同的亮度调节区130，在对显示面板100中的各子显示区10实现单独驱动的基础上，通过对拟输出至对应的亮度调节区130的各子显示区10的各组第二数据信号分别进行调整，将各亮度调节区130的亮度参数设置为沿垂直且远离旋转轴200的方向增大，从而对不同亮度调节区130的平均显示亮度进行调节，使人眼观看到的更靠近旋转轴200的亮度调节区130的平均显示亮度，趋近于或等于更远离旋转轴200的亮度调节区130的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
请参阅图17，本公开的一些实施例提供一种显示装置的驱动方法，应用于上述任一实施例的显示装置1000，该驱动方法包括S1。
S1：栅极驱动电路20所包括的每个栅极驱动子电路21接收一组第一控制信号，生成一组栅极驱动信号，并将该组栅极驱动信号输出至显示面板100中对应的子显示区10所包括的多个亚像素11。
上述驱动方法中，通过一个栅极驱动子电路21驱动对应的子显示区10，能够实现对每个子显示区10的独立驱动，进而可以实现在一个帧周期中对不同子显示区10中的亚像素11同步进行扫描，另外还可以使不同的子显示区10显示不同帧率的画面，以及使不同的子显示区10之间实现异步扫描刷新。
在一些实施例中，在显示装置1000包括源极驱动电路30的情况下，请继续参阅图17，本公开实施例中的驱动方法还包括S21和S22。
S21：源极驱动电路30接收至少两组第二控制信号和至少两组第一数据信号，根据至少两组第二控制信号，将至少两组第一数据信号转化为与显示面板100中的至少两个子显示区10一一对应的至少两组第二数据信号。
S22：将每组第二数据信号输出至对应的子显示区10所包括的多个亚像素11。
在一些实施例中，在显示装置1000为旋转显示装置的情况下，显示装置1000还包括旋转轴200，显示面板100被配置为可围绕旋转轴200旋转；显示面板100具有至少两个亮度调节区130，至少两个亮度调节区130中每个亮度调节区130的长度方向平行于旋转轴200，且至少两个亮度调节区130沿垂直于旋转轴200的方向并列布置；每个亮度调节区130包括至少一个子显示区10。请参阅图18，在将每组第二数据信号输出至对应的子显示区10所包括的多个亚像素11之前，本公开实施例中的驱动方法还包括S23。
S23：源极驱动电路30根据预设的每个亮度调节区130的亮度参数，对转化得到的至少两组第二数据信号分别进行调整，以使至少两个亮度调节区130中的各个亮度调节区130的平均显示亮度相同或者大致相同；其中，沿垂直于旋转轴200且逐渐远离旋转轴200的方向，各亮度调节区130的亮度参数依次增大。
值得一提的是，预设的每个亮度调节区130的亮度参数例如存储在源极驱动电路30中，以便于源极驱动电路30对所述亮度参数进行调用。
根据显示装置的类型的不同，亮度参数可以有多种。
在一些实施例中，显示装置1000包括OLED显示装置、Mini LED显示装置或Micro LED显示装置等电流驱动型显示装置。在上述显示装置中，每个亚像素11在一个帧周期中的有效亮度与该亚像素11接收到的第二数据信号的占空比有关。第二数据信号的占空比决定了对应的亚像素11中发光器件的有效点亮时间，每个亮度调节区130中多个亚像素11的有效点亮时间与该亮度调节区130显示的画面的整体亮度(平均显示亮度)相对应。因此，按照一定的比例调节同一个亮度调节区130中多个亚像素11对应的第二数据信号的占空比，即可调节该亮度调节区130的平均显示亮度。这里需要指出的是，同一个亮度调节区130中包括的各子显示区10的帧频同步，不同亮度调节区130对应的帧频可以相同也可以不同。
基于此，亮度参数包括转化得到的目标亮度调节区130中各子显示区10对应的各组第二数据信号中每个第二数据信号的占空比系数。沿垂直于旋转轴200且逐渐远离旋转轴200的方向，各亮度调节区130的占空比系数的比例，与未对转化得到的至少两组第二数据信号分别进行调整的情况下各亮度调节区130的平均显示亮度的比例，呈反相关的关系。也就是说，未对转化得到的各组第二数据信号分别进行调整的情况下目标亮度调节区130的平均显示亮度越亮，则调整时该目标亮度调节区130对应的占空比系数越小；未对转化得到的各组第二数据信号分别进行调整的情况下目标亮度调节区130的平均显示亮度越暗，则调整时该目标亮度调节区130对应的占空比系数越大。这样调整后，可以使人眼观看到的更靠近旋转轴200的亮度调节区130的平均显示亮度，趋近于或等于更远离旋转轴200的亮度调节区130的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
在一些实施例中，请参阅图19，根据预设的每个亮度调节区130的亮度参数，对转化得到的至少两组第二数据信号分别进行调整，包括S231。
S231：将转化得到的每个亮度调节区130中各子显示区10对应的各组第二数据信号中的每个第二数据信号的占空比乘以该亮度调节区130的占空比系数，得到调整后的该亮度调节区130中各子显示区10对应的各组第二数据信号中的每个第二数据信号。
以桌面级小型近距离边缘轴旋转显示装置为例，请参阅图15，该显示装置1000的显示面板100中包括依次远离旋转轴200的133、132、131共3个亮度调节区130，每个亮度调节区130的长度方向平行于旋转轴200，且3个亮度调节区130沿垂直于旋转轴200的方向并列布置。每个亮度调节区130中均包括3个子显示区10。
源极驱动电路30中存储了预设的3个亮度调节区130中每个亮度调节区130的各亚像素11对应的第二数据信号的占空比系数，即，每个亮度调节区 130中各子显示区10对应的各组第二数据信号中每个第二数据信号的占空比系数。其中，每个亮度调节区130中各亚像素11对应的第二数据信号的占空比系数可以根据实际需要，通过预先的光学模拟及实际亮度测试得出，本公开一些实施例对比不做限定。
亮度调节区131与旋转轴200的垂直距离最远，可选的，预设亮度调节区131中各亚像素11对应的第二数据信号的占空比系数为1，即，源极驱动电路30对转化得到的与亮度调节区131中的3个子显示区10对应的3组第二数据信号不进行调整，直接输出。当然，也可在数据不溢出的情况下适当提高亮度调节区131中各亚像素11对应的第二数据信号的占空比系数，例如，预设亮度调节区131中各亚像素11对应的第二数据信号的占空比系数为1.1；源极驱动电路30对转化得到的与亮度调节区131中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号的占空比分别乘以1.1，得到调整后的亮度调节区131中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。调整后的第二数据信号，例如为PWM(Pulse width modulation，脉冲宽度调制)控制信号。
亮度调节区132与旋转轴200的垂直距离稍近于亮度调节区131与旋转轴200的垂直距离，因此，亮度调节区132中各亚像素11对应的第二数据信号的占空比系数可以预设为预设的亮度调节区131中各亚像素11对应的第二数据信号的占空比系数的0.6～0.9倍。可选的，预设亮度调节区132中各亚像素11对应的第二数据信号的占空比系数为0.8，源极驱动电路30对转化得到的与亮度调节区132中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号的占空比分别乘以0.8，得到调整后的亮度调节区132中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。
亮度调节区133与旋转轴200的垂直距离最近，因此，亮度调节区133中各亚像素11对应的第二数据信号的占空比系数需要小于亮度调节区132中各亚像素11对应的第二数据信号的占空比系数，即小于预设的亮度调节区131中各亚像素11对应的第二数据信号的占空比系数的0.6倍。可选的，预设亮 度调节区133中各亚像素11对应的第二数据信号的占空比系数为0.4，源极驱动电路30对转化得到的与亮度调节区133中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号的占空比分别乘以0.4，得到调整后的亮度调节区133中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。此处，预设的亮度调节区133中各亚像素11对应的第二数据信号的占空比系数不宜过低，例如不低于预设的亮度调节区131中各亚像素11对应的第二数据信号的占空比系数的0.3倍，以免显示装置中的各亚像素11过多的处于低亮度状态，影响显示装置的显示效果。
本公开的一些实施例，利用人眼的视觉暂留现象，设置沿垂直于旋转轴200且逐渐远离所述旋转轴200的方向，各亮度调节区130的占空比系数依次增大，并通过源极驱动电路30按照一定的比例调节每一个亮度调节区130中多个亚像素11对应的第二数据信号的占空比，实现了对各亮度调节区130的平均显示亮度的调节，使人眼观察到的更靠近旋转轴200的亮度调节区130的平均显示亮度，趋近于更远离旋转轴200的亮度调节区130的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
在另一些实施例中，显示装置1000包括LCD显示装置等电压驱动型显示装置。在这种情况下亮度参数包括转化得到的目标亮度调节区130中各子显示区10对应的各组第二数据信号中每个第二数据信号的灰度系数；沿垂直于旋转轴200且逐渐远离旋转轴200的方向，各亮度调节区130的灰度系数的比例，与未对转化得到的至少两组第二数据信号分别进行调整的情况下各亮度调节区130的显示亮度的比例，呈反相关的关系。也就是说，未对转化得到的各组第二数据信号分别进行调整的情况下目标亮度调节区130的平均显示亮度越亮，则调整时该目标亮度调节区130对应的灰度系数越小；未对转化得到的各组第二数据信号分别进行调整的情况下目标亮度调节区130的平均显示亮度越暗，则调整时该目标亮度调节区130对应的灰度系数越大。 这样在调整后，可以使人眼观看到的更靠近旋转轴200的亮度调节区130的平均显示亮度，趋近于或等于更远离旋转轴200的亮度调节区130的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
此处，对于LCD显示装置而言，第二数据信号例如为表征灰度值的信号。
在一些实施例中，请参阅图20，根据预设的每个亮度调节区130的亮度参数，对转化得到的至少两组第二数据信号分别进行调整，包括S232。
S232：将转化得到的每个亮度调节区130中各子显示区10对应的各组第二数据信号中的每个第二数据信号表征的灰度值乘以该亮度调节区130的灰度系数，得到调整后的该亮度调节区130中各子显示区10对应的各组第二数据信号中的每个第二数据信号。LCD显示装置中任一亚像素11的亮度与该亚像素11接收到的第二数据信号表征的灰度值的大小有关，该亚像素11对应的灰度值越大，则该亚像素11中液晶偏转的角度越大，亮度越亮。
以图15中所示的显示装置1000为例，该显示装置1000为LCD显示装置，其显示面板100中包括依次远离旋转轴200的133、132、131共3个亮度调节区130，每个亮度调节区130的长度方向平行于旋转轴200，且3个亮度调节区130沿垂直于旋转轴200的方向并列布置。每个亮度调节区130中均包括3个子显示区10。
源极驱动电路30中存储了预设的3个亮度调节区130中每个亮度调节区130的各亚像素11对应的第二数据信号的灰度系数，即，每个亮度调节区130中各子显示区10对应的各组第二数据信号中每个第二数据信号的灰度系数。其中，每个亮度调节区130中各亚像素11对应的第二数据信号的灰度系数可以根据实际需要，通过预先的光学模拟及实际亮度测试得出，本公开一些实施例对比不做限定。
亮度调节区131与旋转轴200的垂直距离最远，可选的，预设亮度调节区131中各亚像素11对应的第二数据信号的灰度系数为1，即，源极驱动电 路30对转化得到的与亮度调节区131中的3个子显示区10对应的3组第二数据信号表征的灰度值均不进行调整，直接输出。当然，也可在数据不溢出的情况下适当提高亮度调节区131中各亚像素11对应的第二数据信号的灰度系数，例如，预设亮度调节区131中各亚像素11对应的第二数据信号的灰度系数为1.2；源极驱动电路30对转化得到的与亮度调节区131中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号表征的灰度值分别乘以1.2，得到调整后的亮度调节区131中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。
亮度调节区132与旋转轴200的垂直距离稍近于亮度调节区131与旋转轴200的垂直距离，因此，亮度调节区132中各亚像素11对应的第二数据信号的灰度系数可以预设为预设的亮度调节区131中各亚像素11对应的第二数据信号的灰度系数的0.6～0.9倍。可选的，预设亮度调节区132中各亚像素11对应的第二数据信号的灰度系数为0.7，源极驱动电路30对转化得到的与亮度调节区132中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号表征的灰度值分别乘以0.7，得到调整后的亮度调节区132中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。
亮度调节区133与旋转轴200的垂直距离最近，因此，亮度调节区133中各亚像素11对应的第二数据信号的灰度系数需要小于亮度调节区132中各亚像素11对应的第二数据信号的灰度系数，即小于预设的亮度调节区131中各亚像素11对应的第二数据信号的灰度系数的0.6倍。可选的，预设亮度调节区133中各亚像素11对应的第二数据信号的灰度系数为0.5，源极驱动电路30对转化得到的与亮度调节区133中的3个子显示区10对应的3组第二数据信号进行处理，对该3组第二数据信号表征的灰度值分别乘以0.5，得到调整后的亮度调节区133中3个子显示区10一一对应的3组第二数据信号中的每个第二数据信号。此处，预设的亮度调节区133中各亚像素11对应的第二数据信号的灰度系数不宜过低，例如不低于预设的亮度调节区131中各亚像素11对应的第二数据信号的灰度系数的0.5倍，以免显示装置中的各亚像 素11过多的处于低亮度状态，影响显示装置的显示效果。
本公开的一些实施例，利用人眼的视觉暂留现象，设置沿垂直于旋转轴200且逐渐远离所述旋转轴200的方向，各亮度调节区130的灰度系数依次增大，并通过源极驱动电路30按照一定的比例调节每一个亮度调节区130中多个亚像素11对应的第二数据信号表征的灰度值，实现了对各亮度调节区130的平均显示亮度的调节，使人眼观察到的更靠近旋转轴200的亮度调节区130的平均显示亮度，趋近于或等于更远离旋转轴200的亮度调节区130的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
请参阅图22，在一些实施例中，显示面板100具有至少两个不同等级的观看区140，至少两个不同等级的观看区140中每个等级的观看区140包括至少一个子显示区10。请参阅图21，每个栅极驱动子电路21将一组栅极驱动信号输出至显示面板100中对应的子显示区10所包括的多个亚像素11，包括：同一个等级的观看区140内各子显示区10对应的各栅极驱动子电路21，输出表征相同帧率的各组栅极驱动信号至对应的子显示区10所包括的多个亚像素11，使该等级的观看区140内各子显示区10显示的画面的帧率一致；不同等级的观看区140内各子显示区10对应的各栅极驱动子电路21，输出表征不同帧率的各组栅极驱动信号至对应的子显示区10所包括的多个亚像素11，使不同等级观看区140显示的画面的帧率不同；其中，随着观看区140的等级逐渐增大，各观看区140显示的画面的帧率逐渐降低。
本公开的一些实施例可以根据实际需要，对画面中的一部分显示区(例如主观看区域)中的子显示区10设置较高的帧率，对画面中的另一部分显示区(例如非主观看区域)中的子显示区10设置较低的帧率，相比于对整个显示面板100设置较高帧率的方式，能够有效降低源信号的数据量，从而有效降低数据传输的整体带宽。
示例性的，请参阅图22所示的显示装置，其可以应用于例如AR显示或 VR显示等应用场景中。该显示装置的显示面板100具有Ⅰ、Ⅱ、Ⅲ共3个不同等级的观看区140，各级观看区140的位置如图22所示。在3个不同等级的观看区140中，Ⅰ级观看区140包括1个子显示区10，该子显示区10对应的栅极驱动子电路21输出表征的帧率为240Hz一组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。Ⅱ级观看区140包括4个子显示区10，该4个子显示区10对应的4个栅极驱动子电路21分别输出表征的帧率为120Hz的4组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。Ⅲ级观看区140包括4个子显示区10，该4个子显示区10对应的4个栅极驱动子电路21分别输出表征的帧率为90Hz的4组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。由此，Ⅰ级观看区140中的1个子显示区10所显示的画面的帧率为240Hz，Ⅱ级观看区140中的4个子显示区10所显示的画面的帧率为120Hz，Ⅲ级观看区140中的4个子显示区10所显示的画面的帧率为90Hz，实现了观看者观看显示画面时，靠近显示面板100中心处的画面帧率较高，靠近显示面板100边缘处的画面帧率较低，相比于对整个显示面板100设置较高帧率的方式，能够有效降低输入显示装置的源信号的数据量，从而有效降低数据传输的整体带宽。
示例性的，请参阅图15所示的显示装置1000，其可以应用于例如旋转显示等应用场景中。该显示装置1000的显示面板100具有Ⅰ、Ⅱ、Ⅲ共3个不同等级的观看区140，各级观看区140的位置如图15所示。在3个不同等级的观看区140中，Ⅰ级观看区140包括6个子显示区10，该6个子显示区10对应的6个栅极驱动子电路21输出表征的帧率为10000Hz的6组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。Ⅱ级观看区140包括6个子显示区10，该6个子显示区10对应的6个栅极驱动子电路21分别输出表征的帧率为70000Hz的6组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。Ⅲ级观看区140包括6个子显示区10，该6个子显示区10对应的6个栅极驱动子电路21分别输出表征的帧率为5000Hz的6组栅极驱动信号至对应的子显示区10所包括的多个亚像素11。由此，Ⅰ级观看区140中的6个 子显示区10所显示的画面的帧率为10000Hz，Ⅱ级观看区140中的6个子显示区10所显示的画面的帧率为7000Hz，Ⅲ级观看区140中的6个子显示区10所显示的画面的帧率为5000Hz，实现了观看者观看显示画面时，沿远离旋转轴200的方向，显示的画面的帧率逐渐增大。
一方面，相比于对整个显示面板100设置较高帧率的方式，上述设置不同等级观看区140对应不同的帧率的方式能够有效降低输入显示装置的源信号的数据量，从而有效降低数据传输的整体带宽。另一方面，由于人眼的视觉暂留现象，对于同一幅画面，如果显示时的帧率较高，人眼观察到的画面整体亮度则较亮；如果显示时的帧率较低，人眼观察到的画面整体亮度则较暗。因此，在旋转显示时，如果显示面板100中的所有亚像素11显示的画面帧率同步，人眼观看到的画面会呈现出内亮外暗的效果，本公开一些实施例通过对不同等级观看区140设置不同的帧率，且沿远离旋转轴200的方向各观看区140显示画面的帧率逐渐增大，能够对不同等级观看区140的平均显示亮度进行调节，可以使人眼观看到的更靠近旋转轴200的观看区140的平均显示亮度，趋近于更远离旋转轴200的观看区140的平均显示亮度，从而改善了显示装置的三维体素点阵在显示画面时内亮外暗的情况，使观看者观看到的立体画面的亮度更加均匀，实现较好的旋转显示装置体素均匀化效果。
值得一提的是，在改善旋转显示装置在显示画面时内亮外暗的情况时，采用调整第二数据信号的亮度参数的方式，或者采用对不同等级观看区140设置不同的帧率的方式，均可。当然，上述两种方式也可以同时采用，本公开一些实施例对此不做限定。
