所述显示屏10，包括但不限于量子点显示屏(Quantum Dot Light Emitting Diodes，QLED)、有机发光二极管显示屏(Organic Light-Emitting Diode，OLED)等，此处不做限定。
所述存储器20可用于存储计算机程序和/或模块，所述处理器30通过运行或执行存储在所述存储器20内的计算机程序和/或模块，以及调用存储在存储器20内的数据，实现所述显示装置100的各种功能。所述存储器20可主要包括程序存储区和数据存储区，其中，程序存储区可存储操作系统、多个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；数据存储区可存储根据音响的使用所创建的数据(比如音频数据、显示数据等)等。
此外，所述存储器20可以包括高速随机存取存储器，还可以包括非易失性存储器，例如硬盘、内存、插接式硬盘，智能存储卡(Smart Media Card，SMC)，安全数字(Secure Digital，SD)卡，闪存卡(Flash Card)、多个磁盘存储器件、闪存器件、或其他易失性固态存储器件。

具体地，在一个实施例中，所述显示装置100还包括定位装置50。所述处理器30用于通过所述定位装置50确定用户相对于所述显示装置100的位 置，并根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域(如图2中S区域)。所述处理器30还用于控制在所述当前显示区域中显示当前显示内容。其中，所述当前显示内容可以是原本显示于整个显示屏10中的当前显示内容，还可以是显示于显示屏10中部分显示区域中的显示内容。在本实施方式中，部分显示区域可以是相对于用户的之前的位置的可视区域，当用户的位置发生变化时，显示内容从之前的部分显示区域中转移到当前显示区域中。
本申请所公开的显示装置100能够根据用户的位置确定显示屏10的当前显示区域，并控制在所述当前显示区域中显示所述显示屏10中的当前显示内容，进而使得用户能够实时观看到完整的显示内容，提高了用户体验。
在一个实施方式中，所述处理器30根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域，包括：所述处理器30根据用户相对于所述显示装置100的位置确定所述显示装置100可被用户观看到的可视区域，确定所述可视区域为所述显示屏10的当前显示区域。
请再结合参阅图2，在一些实施方式中，根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域S，包括：所述处理器30确定经过所述用户相对于所述显示装置100的位置的所述显示屏10的法线与所述显示屏10的交点，所述处理器30还将经过所述交点且与水平面垂直的直线作为对称轴a，并确定以所述对称轴a对称的预设区域为所述当前显示区域S。
请再参阅图3，在一些具体的实施例中，所述显示装置100为音箱，所述显示装置100呈圆柱状，所述显示屏10为柔性显示屏，所述显示屏10可弯曲地设置于所述所述显示装置100的圆柱面上。当所述显示屏10处于展开状态时，所述显示屏10为矩形，所述显示屏10包括相互平行的一对第一侧边11以及垂直于所述第一侧边的一对第二侧边12。在本实施方式中，所述第一侧边11较长，且所述第二侧边12较短。当所述显示屏10沿着较长的一对第一侧边11卷曲，且使得所述较短的一对第二侧边12接触时，所述显示屏10呈圆柱状(如图3所示)。其中，所述展开状态是指所述显示屏10没有发生任何折叠，处于水平展开状态。
在本实施方式中，所述显示屏10为环绕所述显示装置100的圆柱侧面， 所述显示装置100还包括与所述显示屏10构成的圆柱侧面的两端接合的两个圆形的端面。具体地，所述的第一侧边11的长度为显示装置100在其中一个端面上的投影的周长，所述第二侧边的长度为所述显示装置100的高。
请再参阅图4，进一步地，所述处理器30根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域S，包括：所述处理器30确定经过所述用户相对于所述显示装置100的位置的所述显示屏10的法线与所述显示屏10的交点，将经过所述交点且与所述第二侧边12平行的直线作为对称轴a，确定以所述对称轴a对称的预设区域为所述当前显示区域S。其中，所述预设区域可以是圆形、方形、椭圆形或者其他轴对称图形。可以理解，不论所述预设区域的形状如何，所述预设区域均为可被用户看到的可视区域。
在本实施方式中，用户相对于所述显示装置100的位置为用户视点中心垂线位置。其中，视点中心为连接左右眼视点的线段的中点；用户视点中心垂线位置是指经过用户视点中心的垂直方向的直线。
进一步地，所述处理器30确定以所述对称轴a对称的预设区域为所述当前显示区域，包括：所处处理器30确定以所述对称轴a为中心且以预设长度1为对称距离的预设区域确定为所述当前显示区域S。在本实施方式中，所述预设区域为矩形，且所述预设区域的一对边的边长与所述显示装置100的高度相同。其中，所述预设长度1小于或等于可被用户观看到的可视区域的极限长度L的一半。即，当所述预设长度1大于极限长度L的一半L’时，所述当前显示区域将不会全部落入到用户的视线范围内。
具体地，请再结合参阅图5，在本实施例中，当显示装置100为圆柱体时，用户与显示装置100的显示屏10的最短距离为q，显示装置100的端面半径为r。当所述显示屏10卷曲后，所述显示装置100的端面半径r与第一侧边11的长度h的关系为：r＝h/2π。设用户与显示装置100的中心的距离为q+r，极限长度L的一半L’所对对应的中心角θ，由于用户的视线与显示装置100侧面的切线与所述半径r垂直，因此，cosθ＝r/(r+q)，则θ＝arcos[r/(r+q)]，根据该公式可以计算出中心角度θ的数值。进一步地，极限长度L的一半L’＝θ*h/360＝θ*πr/180。由上述公式可以看出，极限长度L’与用户与显示装置100的显示屏10的最短距离q和显示装置100的端面半径r相关。
因此，本申请所公开的显示装置100，当用户的位置改变时，所述当前显示区域的位置也会随着改变，进而使得所述显示屏10中所显示的内容都会本用户看到，进而提高了用户体验。可以理解，所述当前显示区域的面积可以根据不同的需求而进行设定，只要保证当前显示区域全部落入用户实现范围即可。
在一些实施例中，所述处理器30通过所述定位装置确定用户相对于所述显示装置100的位置，包括：所述处理器30通过所述定位装置检测到的用户状态信息来确定用户相对于所述显示装置100的位置。其中，所述用户状态信息包括声音、体温、面部图像等。
具体地，请再参阅图6，在一些实施方式中，所述定位装置50为麦克风阵列，所述麦克风阵列包括多个麦克风以单独获取相应的音频信号。进一步地，所述处理器30通过所述定位装置50来确定用户相对于所述显示装置的位置，包括：所述处理器30通过所述麦克风阵列50的多个麦克风获取的单独的音频信号来确定用户相对于所述显示装置100的位置。例如，用户可以向显示装置100发出语音。所述处理器30通过所述麦克风阵列50接收到的用户发出的语音信号的方向来确定用户相对于显示装置100的位置。当用户的位置确定后，所述处理器30即可确定出当前显示区域，进而控制在所述当前显示区域中显示当前显示内容。可以理解，当所述显示装置100刚开机或者未接收到用户的语音命令时，所述处理器30控制所述当前显示内容显示于整个显示屏10中，只有当用户发出语音后，才根据用户的语音确定用户的位置。
另外，需要说明的是，本实施方式中的音频信号为用户所发出的语音，对于环境中的噪音所述显示装置100并不响应，即所述处理器30还对获取的音频信号进行识别，当判断所述音频信号为用户所发出的语音信号时，才确定用户相对于显示装置100的位置。在其他实施例中，所述处理器30还用于判断所述获取的音频信号是否为特定的语音指令，当所述音频信号与特定的语音指令相匹配时，才确定用户相对于所述显示装置100的位置。例如，可以在所述存储器20预先存有的如“小爱同学”、“小扬先生”等特定语音指令，当所述处理器30判断通过所述麦克风阵列所获取的语音信号与特定的语音指令相匹配时，确定用户相对于所述显示装置100的位置。具体地，请再参阅图6， 在一个的实施例中，所述麦克风阵列50可以包括多个单独的麦克风，每个麦克风用于获取单独的声音信号。在本实施方式中，所述麦克风阵列50可以由5个单独的麦克风M1-M5组成，且所述多个麦克风沿所述显示屏10的卷曲方向呈圆形分布，进而能够提高判断用户相对于所述显示装置100的位置的准确率。优选地，所述多个麦克风设置于所述显示装置100用于与用户交互的端面上，且呈圆形分布。可以理解，在其他实施方式中，所述麦克风的数量和分布位置并不限于此。例如，当显示装置100放置于房间内且一面靠近墙壁或者其他物体时，所述麦克风阵列50可以包括数量更少的麦克风，并且呈半圆形分布即可。
在一些实施方式中，所述处理器30可以根据多个麦克风中每个麦克风接收的声音信号相对彼此的延迟来确定用户的位置，还可以根据多个麦克风中每个麦克风接收的声音信号相对于彼此的幅度差异来确定用户的位置。在其他实施方式中，所述定位装置50还可为红外探测器以通过检测人体的温度信息来确定用户相对于所述显示装置100的位置。在另一些实施例中，所述定位装置50还可以是摄像头阵列，即通过摄像头侦测的图像信息来确定用户相对于所述显示装置100的位置。
请再参阅图7，所述显示屏10包括呈行列排布的多个发光单元11以及驱动电路12。所述驱动电路12与多个发光单元11电连接，并用于驱动多个发光单元11发光进行显示。所述处理器控制在所述当前显示区域中显示所述显示屏中的当前显示内容，包括：处理器30通过控制驱动电路12驱动当前显示区域内的多个发光单元11发光以显示当前显示内容。其中，每个发光单元11可以对应一个像素点。
在一些实施例中，所述处理器30还控制所述显示屏10中的所述当前显示区域之外的其他显示区域内的多个发光单元11不发光，而控制所述显示屏中的所述当前显示区域之外的其他显示区域关闭，进而降低所述显示装置100的能耗。此外，所述处理器30还可以通过调整所述当前显示区域内显示内容的显示属性来降低显示装置100的能耗。其中，所述显示显示属性包括当不限于，分辨率、显示亮度、透明度等。例如，通过降低当前显示内容的分辨率来降低能耗。在其他实施方式中，所述处理器30还控制所述显示屏10中的所述 当前显示区域之外的其他显示区域显示一背景图案以衬托当前显示内容。其中，背景图案包括但不限于以纯色(例如，灰色、棕色、紫色等)进行显示的背景板、包括有特定图案(例如，动物影像、植物影像、人物影像等)的背景板、包括特定形状(方形、圆形、星形、心形等)的背景板等，此处不做限定。此外，需要说明的是，背景图案的内容还可以随着时间的变化而动态改变。
此外，在另一些实施例中，所述处理器30还控制所述显示屏10中当前显示区域之外的其他显示区域内的多个发光单元11发光以控制将当前显示内容同时显示于所述显示屏10中的所述当前显示区域之外的其他显示区域上，进而可以使得位于其他位置的用户也可以观看到显示内容，使得显示装置100能够多方位显示以满足不同用户的需求。在本实施方式中，所述根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域，包括：确定用户相对于所述显示装置100的位置的数量，并根据每个用户相对于所述显示装置的位置分别确定对应的当前显示区域。例如，当确定用户相对于所述显示装置100的位置的数量为N时，则确定N个当前显示区域，且N个当前显示区域互相不重叠，以免影响用户的观看质量。其中，N为大于等于1且小于等于2πr/L的正整数。r为显示装置100的端面半径，L为可视区域的极限长度，进而可以保证在位于不同位置的用户的可视区域内只出现一个当前显示区域，避免了在同一位置的用户的可视区域内出现多个显示内容的情况发生，提高了用户体验。
请参阅图8，图1为本申请一实施例公开的显示控制方法的流程图。所述显示控制方法应用于一显示装置100中，所述显示装置100包括定位装置50、显示屏10和处理器30。如图8所示，所述显示控制方法包括如下步骤：

在本实施方式中，所述处理器30根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域，包括：所述处理器30确定经过所述用户相对于所述显示装置100的位置的所述显示屏10的法线与所述显示屏10的交点，将经过所述交点且与所述第二侧边12平行的直线作为对称轴，确定以所述对称轴对称的预设区域为所述当前显示区域。其中，所述预设区域可以是圆形、方形、椭圆形或者其他轴对称图形。
因此，本申请所公开的显示装置100，当用户的位置改变时，所述当前显示区域的位置也会随着改变，进而使得所述显示屏10中所显示的内容都会本用户看到，进而提高了用户体验。可以理解，所述当前显示区域的面积可以根据不同的需求而进行设定，只要保证当前显示区域全部落入用户实现范围即可。
进一步地，所述处理器30确定以所述对称轴对称的预设区域为所述当前 显示区域，包括：所处处理器30确定以所述对称轴为中心且以预设长度1为对称距离的预设区域确定为所述当前显示区域。在本实施方式中，所述预设区域为矩形，且所述预设区域的一对边的边长与所述显示装置100的高度相同。其中，所述预设长度小于或等于可被用户观看到的极限长度的一半。即，当所述预设长度大于极限长度的一半时，所述当前显示区域将不会全部落入到用户的视线范围内。
在一些实施例中，所述通过所述定位装置50确定用户相对于所述显示装置100的位置，包括：通过所述定位装置50检测到的用户状态信息来确定用户相对于所述显示装置100的位置。具体地，请再参阅图1，所述显示装置100还包括麦克风阵列50，所述麦克风阵列包括多个麦克风以单独获取相应的音频信号。
在另一些实施例中，所述定位装置50为麦克风阵列，所述麦克风阵列包括多个麦克风以单独获取相应的音频信号；所述通过所述定位装置50确定用户相对于所述显示装置的位置，包括：通过所述麦克风阵列50的多个麦克风获取的单独的音频信号来确定用户相对于所述显示装置100的位置。
在一个的实施例中，所述麦克风阵列可以包括多个单独的麦克风，每个麦克风用于获取单独的音频信号。在本实施方式中，所述麦克风阵列可以由5个单独的麦克风M1-M5组成，且所述多个麦克风沿所述显示屏10的卷曲方向呈圆形分布，进而能够提高判断用户相对于所述显示装置100的位置的准确率。优选地，所述多个麦克风设置于所述显示装置100用于与用户交互的端面上，且呈圆形分布。可以理解，在其他实施方式中，所述麦克风的数量和分布位置并不限于此。例如，当显示装置100放置于房间内且一面靠近墙壁或者其他物体时，所述麦克风阵列可以包括数量更少的麦克风，并且呈半圆形分布即可。
请再参阅图10，在一些实施方式中，所述显示控制方法还包括如下步骤：
步骤S101，控制所述显示屏10中所述当前显示区域之外的显示区域关闭或显示背景图案。
其中，背景图案包括但不限于以纯色(例如，灰色、棕色、紫色等)进行显示的背景板、包括有特定图案(例如，动物影像、植物影像、人物影像等) 的背景板、包括特定形状(方形、圆形、星形、心形等)的背景板等，此处不做限定。此外，需要说明的是，背景图案的内容还可以随着时间的变化而动态改变。
在本实施方式中，由于控制显示屏10中当前显示区域之外的其他显示区域关闭，进而能够降低所述显示装置100的能耗。此外，还可以通过调整所述当前显示区域内显示内容的显示属性来降低显示装置100的能耗。其中，所述显示显示属性包括当不限于，分辨率、显示亮、透明度等。例如，通过降低当前显示内容的分别率来降低能耗。此外，还可以通过显示背景图案来对显示内容进行衬托。
此外，在一些实施例中，所述控制方法在控制将显示于所述显示屏10中的当前显示内容同时显示于所述显示屏10中的所述当前显示区域之外的其他显示区域上。在本实施方式中，由于在显示屏10中当前显示区域之外的其他显示区域还显示与当前显示区域中相同的显示内容，进而可以使得位于其他位置的用户也可以观看到显示内容，使得显示装置100能够多方位显示以满足不同用户的需求。
在本实施方式中，所述根据用户相对于所述显示装置100的位置确定所述显示屏10的当前显示区域，包括：确定用户相对于所述显示装置100的位置的数量，并根据每个用户相对于所述显示装置的位置分别确定对应的当前显示区域。例如，当确定用户相对于所述显示装置100的位置的数量为N时，则确定N个当前显示区域，且N个当前显示区域互相不重叠，以免影响用户的观看质量。其中，N为大于等于1且小于等于2πr/L的正整数。r为显示装置100的端面半径，L为可视区域的极限长度。本实施方式中，当位于所述显示装置100的多个方位有不同的用户时，所述显示装置100可以确定多个当前显示区域并分别对应一个方位的用户，从而使得不同方位的用户同时观看到完整的显示内容，进一步提升用户体验。
