参见图5A，为本申请一些实施例提供的图1中显示设备的横屏状态的示意图。显示器275处于横屏状态时的操作模式可以称为横屏媒资观看模式，显示器275处于竖屏状态时的操作模式可以称为竖屏媒资观看模式。图5中，能够直观看到的即为显示设备200中的显示器275，该显示设备200中的控制器250进一步与服务器300通信连接，用于调用服务器300的接口，获取相应数据。该显示设备200中的显示器275能够被旋转组件276驱动旋转，并用于显示用户界面。在实际应用中，用户可通过控制装置100来控制显示设备200的播放模式、播放内容等，其中，播放模式包括横屏媒资观看模式和竖屏媒资观看模式。
在一种实现方式中，显示设备200包括旋转组件276，该旋转组件276能够将显示设备200进行固定，并能够在控制器250的控制下，控制显示器275旋转以使显示器275处于横屏状态或竖屏状态。该旋转组件276可以固定在显示器275的背面，旋转组件276用于和墙面固定，且旋转组件276接收控制器250的控制指令，使显示器275在竖直的平面内进行旋转，使得显示器275处于横屏状态或竖屏状态。
其中，所述横屏状态是指，从显示器275正面观看时，所述显示器275水平方向上的长度(宽)大于竖直方向上的长度(高)的状态；所述竖屏状态是指，从显示器275正面观看时，所述显示器275水平方向上的长度(宽)小于竖直方向上的长度(高)的状态。显然，所述竖直方向在本申请中是指大致竖直，水平方向也是指大致水平即可。
在旋转组件276的驱动下，显示器275可以顺时针或逆时针旋转90度，以显示器275处于竖屏状态，如图5B所示。在竖屏状态下，显示器可以显示竖屏状态对应的用户界面，并拥有竖屏状态相对应的界面布局和交互方式。在竖屏媒资观看模式下，用户可以观看短视频、漫画等竖屏媒资。同理，由于显示设备200中的控制器250进一步与服务器300通信连接，因此可以在竖屏状态时，通过调用服务器300的接口，获取竖屏相应的媒资数据。
竖屏状态更适合播放画面比例为9：16等竖屏形式的媒资，例如，通过手机等终端拍摄的短视频等。由于手机等终端设备多采用9：16，9：18等竖向屏幕比例，因此在终端接入显示设备200，并通过显示设备200显示终端画面时，竖屏状态能够避免对画面进行过渡缩放，充分利用显示器275的显示画面，拥有更好的用户体验。
需要说明的是，横屏状态主要用于显示电视剧、电影等横向媒资，竖屏状态主要用于显示短视频、漫画等竖向媒资。上述横屏状态和竖屏状态只是两种不相同的显示器状态，并不对显示的内容构成限制，例如，在横屏状态下依然可以显示短视频、漫画等竖向媒资；在竖屏状态下也依然可以显示电视剧、电影等横向媒资，只是在该状态需要对不相符的显示窗口进行压缩、调整。
显示设备200可以通过显示器275为用户提供显示画面，可以提供多个显示层级，例如画质层、UI层等。其中，所述画质层是指用户在播放媒资后，显示设备200上用于呈现播放画面的显示层级，也可以称为显示设备200的Video层。在画质层可以显示媒资对应的播放画面。所述UI层(User Interface)是指用于为用户提供交互操作的显示层级，也可以称为显示设备200的OSD(On-Screen Display)层。UI层可以显示各种交互控件，例如控制主页。
根据显示器275不同的旋转状态，显示器275上所呈现的主页模式也不同，例如在一种实现方式中，显示设备200启动中，检测到当前显示器275处于横屏状态。则控制器250请求调用服务器300的接口，向服务器300发送横屏主页数据的获取请求。服务器300响应于该获取请求，并将横屏主页数据下发至控制器250。控制器250对横屏主页数据进行识别，并根据横屏主页数据控制显示器275显示出横屏主页。
在本申请示例性的实施例中，在显示器275处于竖屏状态时，响应于操作指令，控制旋转组件276旋转以使显示器275由当前竖屏状态转换为横屏状态，并请求调用服务器300的接口，向服务器300发送横屏主页数据的获取请求。服务器300响应于该获取请求，并将横屏主页数据下发至控制器250。控制器250对横屏主页数据进行识别，并根据横屏主页数据控制显示器275显示出横 屏主页。
为了获得更好的观看体验，在显示不同的媒资时，可以通过旋转组件276来调整显示器275的横屏状态和竖屏状态，即，显示器275能够根据用户需求进行旋转，用户可根据观看需求，向控制器250发送触发旋转的操作指令，控制器250接收并响应于用户发送的触发旋转的操作指令，转换显示器275的旋转状态，旋转状态可以包括横屏状态或竖屏状态，横屏状态对应横屏媒资观看模式，竖屏状态对应竖屏媒资观看模式。
在一种实现方式中，显示设备200的控制器250可以通过检测显示器275中显示的画面比例来确定是否需要旋转显示器275。例如，用户在横屏状态下播放了短视频、漫画等竖向媒资，控制器250可以检测到该竖向媒资与当前的横屏状态不相符时，自动对旋转组件276进行控制，以将显示器275转动90度，调整为竖屏状态。
由于旋转组件276的转动过程比较缓慢，因此，在转动过程中，用户需要长时间观看倾斜的画面。例如，显示器275从横屏状态到竖屏状态需要顺时针转动90度，转动过程共需要15s，则在15s内显示器275中的画面会随着显示器275的转动，不断倾斜，直到显示器275转动到竖屏状态后，再通过将画面逆时针转动90度，以呈现为竖屏显示。
为了减少倾斜时间，改善用户体验，本申请可以在画质层对显示画面进行同步旋转，以使得在旋转过程中，显示器275上显示的画面始终为正向。其中，画质层为显示设备200所对应操作系统中的一个显示层级。区别于UI层，画质层可以很方便的对画面进行画质、缩放比例、方向进行调整。一般，媒资对应的播放画面在画质层进行展示，因此，在画质层进行同步旋转可以无需考虑视 频资源的来源，对所有媒资都能够进行调整。
当用户播放与当前旋转状态不相符的媒资时，需要对显示器276进行旋转以适应不相符的媒资画面，具体处理如下：
首先，选择视频进行播放。用户可以根据自身需求，通过UI界面上的一系列操作，进行视频播放。例如，用户可以通过在控制装置100上实施操作，在主页上依次选择“精选”-“我的应用”-“短视频”，进入短视频应用界面。并且在短视频对应的应用界面中，选择任一视频进行播放。显然，本申请中，视频资源包含本地，DLNA(Digital Living Network Alliance，数字生活网络联盟)推送，DMS(Database Management System，数据库管理系统)共享等来源的视频资源。
为了适应不同的显示，供用户操作的主页也可以包括横屏主页和竖屏主页两种形式，并且在不同的主页模式中，可呈现的内容也可以不同。例如，在横屏主页模式下，主页中可以呈现较多的电影、电视剧等类型的横向媒资或链接，以供用户直接进行选择播放。而竖向媒资则可以归类于一个或多个控件中，例如“短视频”应用图标，用户需要点击对应的控件后，才能够选择竖向媒资或链接进行播放。
其次，对播放的视频进行检测。在用户确定要打开的视频资源后，控制器250会对视频资源进行解码，并转化为视频画面在显示器275上进行展示。在控制显示器275展示视频画面的同时，控制器250还可以对画面的显示宽高比与显示器275的旋转状态进行检测，确定当前显示的画面宽高比是否与当前显示器275的旋转状态相适应。
例如，如果当前展示的画面为竖向媒资，且显示器275为竖屏状态，则当 前显示的画面宽高比与当前显示器275的旋转状态相适应，无需进行旋转调整；如果当前展示的画面为竖向媒资，但显示器275为横屏状态，则当前显示的画面宽高比与当前显示器275的旋转状态不适应，需要进行旋转调整。
最后，进行旋转调整。对于需要进行旋转调整的情况，控制器250触发旋转组件276旋转，以调节显示器275的旋转状态；同时可以在画质层对显示的画面进行相反方向的旋转调节，以使得显示的画面能够在显示器275旋转的过程中，始终保持在正向显示的状态。
在本申请的一些实施例中，当前播放的画面为竖向媒资，而当前显示器275为横屏状态，则控制器250一方面向旋转组件276发送控制其进行转动的指令，使旋转组件276可以带动显示器275顺时针旋转90度，调整显示器275的旋转状态为竖屏状态。可以在画质层调整当前显示画面，将当前显示画面进行旋转和/或缩放，使当前显示画面得以平缓的逆时针进行转动90度。由于在转动过程中显示画面的顺时针转动可以抵消显示器275逆时针转动所带来的倾斜，因此显示画面始终保持为正向显示的状态。
如图6所示，为本申请一种显示画面旋转适配方法的流程示意图。对于实际的控制过程，本申请中所述控制器250被进一步配置为执行以下程序步骤：
S1：响应于显示设备的视频媒体资源播放动作，检测所述显示器的当前旋转状态。
用户在控制主页上选定一个媒资，并进行播放，即在显示设备200中产生一个视频媒体资源播放动作。例如，用户通过“精选-我的应用-短视频”打开短视频应用后，在多个短视频资源图标下选择一个进行播放。
控制器250在监听到视频媒体资源播放动作后，可以通过旋转组件276上 的角度传感器或者显示器275上的重力加速度传感器确定显示器275当前的旋转状态。例如，通过对重力加速度传感器测得的数据分析可以确定当前显示器275的重力方向垂直于长边，则确定显示器275当前处于横屏状态。
S2：如果所述视频媒体资源的画面比例与所述当前旋转状态匹配，控制所述显示器显示所述视频媒体资源对应的画面。
控制器250可以在视频媒体资源的文件描述信息中，确定视频媒体资源对应的显示画面比例。例如，播放的视频媒体资源为短视频，其显示画面比例为9:16，确定当前短视频为竖向媒资。如果此时显示器275的旋转状态也为竖屏状态，即视频媒体资源的画面比例与所述当前旋转状态匹配，此时，直接控制显示器显示视频媒体资源对应的画面即可。
S3：如果所述视频媒体资源的画面比例与所述当前旋转状态不匹配，控制所述旋转组件旋转所述显示器，以使所述显示器适应所述视频媒体资源的画面比例以及播放所述视频媒体资源对应的画面。
在本申请一些示例性的实施例中，显示器275的当前旋转状态为横屏状态，播放的视频媒体资源为短视频等竖向媒资，则确定视频媒体资源的画面比例与所述当前旋转状态不匹配，此时，可以控制旋转组件276旋转显示器275至竖屏状态，以适应所播放的短视频对应的显示画面比例。
需要说明的是，在本申请提供的技术方案中，画面比例与旋转状态之间是否匹配是指：所播放的视频媒体资源的宽高比是否与显示器275屏幕的宽高比相同或者具有相似的比例关系。例如，传统电影、电视剧等横向媒资，其画面的宽度要大于高度，即横向媒资的宽高比通常大于1。而显示器275在横屏状态下时，长边处于水平状态作为宽，短边处于竖直状态作为高，则横屏状态下 显示器275的宽高比也大于1；同理，对于短视频、漫画等竖向媒资，其画面的宽度小于高度，即竖向媒资的宽高比小于1，而显示器275在横屏状态下时，长边处于竖直状态作为高，短边处于水平状态作为宽，则竖屏状态下显示器275的宽高比也小于1。
本申请中，如果所述视频媒体资源的画面宽高比与显示器275的宽高比同时大于1或者同时小于1，则确定所述视频媒体资源的画面比例与所述当前旋转状态匹配。即，横向媒资的画面比例与横屏状态匹配；竖向媒资的画面比例与竖屏状态匹配。同理，如果所述视频媒体资源的画面宽高比与显示器275的宽高比不是同时大于1或者同时小于1，则确定所述视频媒体资源的画面比例与所述当前旋转状态不匹配。例如，竖向媒资的画面比例与横屏状态不匹配；横向媒资的画面比例与竖屏状态不匹配。
为了获得显示画面的宽高比，控制器250可以在用户选择播放某一资源后，通过资源的描述信息中获取。对于大部分资源其文件描述中会指定其画面比例，例如文件描述信息为：4096×2160，则确定其宽高比为4096:2160＞1。也可以通过对显示图像在宽度和高度上所占用的有效像素点进行查询，确定显示画面的宽高比。例如，出插黑区域所占的像素点外，显示画面的所占据的有效像素点在宽度和高度上分别为720和1280个像素点，则其宽高比为720:1280＜1。
在一种实现方式中，如图7所示，控制器250还被配置为执行以下程序步骤：
S111：检测所述旋转组件的开关状态。
在选择播放的视频资源后，控制器250可以显示设备200的旋转开关进行检测，确定旋转组件276是否处于开启的状态。显然，旋转组件276的开关状 态可以是指硬件上的开关状态，即旋转组件276的控制电路是否上电；也可以是指软件上的开关状态，即在操作系统中，旋转组件276对应的控制程序为激活的状态。
S112：如果所述开关状态为开启，检测所述视频媒体资源对应显示画面的宽高比以及所述显示器的当前旋转状态。
如果旋转组件276的开关状态为开启，即当前旋转组件276可以随时受到系统控制而启动运行。此时，控制器250可以进一步对当前所述视频媒体资源对应显示画面的宽高比与当前显示器的旋转状态进行检测，从而根据检测结果确定是否需要旋转显示器275和显示画面。
显示画面的宽高比，是指显示画面边缘的宽度与高度之间的比值。需要说明的是，此处显示画面边缘是指有效显示画面的边缘，例如视频边缘或者图像的边缘，不包括为了适应画面而填充的黑色区域。例如，当前显示画面为竖向媒资，其画面宽度为360像素，画面高度为640像素，则对应的宽高比为360：640；而当前显示器275为横屏状态，显示分辨率为3840×2160，即屏幕显示区域宽高比3840：2160，则确定当前显示画面的宽高比与当前显示器的旋转状态不一致。
由于视频资源画面比例差异较大，因此为了适应多种资源类型，对于显示画面的宽高比，可以通过具体的比值将其进行归类。显示画面的宽高比如果大于1，即画面的宽度大于高度，则视频资源为横向媒资；同理，显示画面的宽高比如果小于1，即画面的宽度小于高度，则视频资源为竖向媒资。
相应的，对于当前显示画面的宽高比与当前显示器的旋转状态是否相适应的判断，可以通过对显示画面的宽高比进行判断。如果宽高比大于1，说明视频 是较宽的视频，此时若显示器275是横屏状态则不需要驱动显示器275旋转，如果若显示器275是竖屏状态则需要旋转显示器275至横屏；如果宽高比小于1，说明视频是较高的视频，如果若显示器275是横屏状态则需要旋转显示器275，若显示器275是竖屏状态则不需要驱动显示器275旋转。
在本申请示例性的一些实施例中，在检测所述旋转组件的开关状态的步骤后，所述控制器250还被进一步配置为：
S113：如果所述开关状态为关闭，控制所述显示器呈现设置画面。
当检测到旋转组件276的开关状态为关闭时，旋转组件276不能直接被控制以完成旋转操作，因此需要通知用户开启旋转组件276的开关。例如，在显示器275上显示设置画面，即“设置”对应的UI界面，以供用户开启旋转组件276。
还可以通过对显示设备200上启动的应用进行判断，确定显示画面比例与旋转状态是否匹配。通常，显示设备200上安装的应用可以包括三类，其一，仅支持横屏状态的应用，如云视听、小电视、爱奇艺等电影电视类app，如果在竖屏状态打开此类应用，则控制显示器275旋转至横屏状态；其二，仅支持竖屏状态的应用，如快手、抖音等短视频app，如果在横屏状态打开此类应用，则控制显示器275旋转至竖屏状态；其三，既支持横屏状态又支持竖屏状态的应用，如应用商店、视频通话、游戏等app，这类应用在打开时可以无需旋转显示器275，但需要根据显示器275的旋转状态调整应用界面显示布局。
在一种实现方式中，如图8所示，控制器250还被配置为执行以下程序步骤：
S121：接收用户输入的用于旋转所述显示器的旋转指令。
所述旋转指令是指用于触发旋转操作的指令，可以是由用户主动发起，也可以由控制器250通过判断当前显示状态自动发起。需要说明的是，旋转指令旨在触发旋转操作，在实际应用中可能并不存在相应的用户指令，例如，控制器250在判断当前播放的画面为竖向媒资，而当前显示器275为横屏状态时，可以自动触发旋转操作，无需额外生成一个旋转指令。因此，对于本领域的技术人员而言，是否只要触发旋转操作，都属于本申请的保护范围。
用户通过控制装置100，可以通过实施不同操作，以生成触发旋转组件276进行旋转的控制指令。用户所执行的操作，可以直接在UI界面上以控件的形式进行展示，也可以在UI界面动态进行显示。即，控制器250可以通过检测播放视频的宽高比与当前显示器275的旋转状态，实时调整UI界面上的控件显示情况。
例如，用户在选择“短视频”应用中的一个视频资源进行播放时，控制器250检测播放视频的宽高比为竖向媒资，与当前显示器275的横屏状态不一致，则在UI界面中显示诸如以下提示文字及控件“检测到当前视频资源更适合竖屏观看，是否自动切换到竖屏状态”、“是/否”。当用户选择“是”时，即生成对应的用户输入，并将用户输入发送给控制器250。
S122：将所述旋转指令发送至所述旋转组件，以控制所述旋转组件启动转动。
对于用户主动发送的旋转指令，控制器250需要对用户的输入进行解析，确定显示器275的旋转策略。例如，当用户想要将显示器275从横屏状态调节为竖屏状态时，旋转指令可以控制旋转组件276顺时针转动90度；当用户想要将显示器275从竖屏状态调节为横屏状态时，旋转指令可以控制旋转组件276 逆时针转动90度。
在一种实现方式中，如果所述视频媒体资源的画面比例与所述当前旋转状态不匹配，所述控制器250被进一步配置为：
S31：根据所述当前旋转状态和所述视频媒体资源的画面比例，计算旋转参数。
控制器250可以根据当前旋转状态和视频媒体资源的画面比例确定控制对显示器275进行旋转。例如，当前显示器275的旋转状态为横屏状态，视频媒体资源的画面比例为竖向时，可指定需要将显示器275旋转至竖屏状态，即显示器275顺时针转动90度的指令。
S32：按照所述旋转参数调整显示所述视频媒体资源对应的画面。
为了在旋转显示器275时，获得更好的观看体验。控制器250可以使显示的画面与显示器275同时转动，以使显示画面始终保持在正向状态，因此所述旋转参数包括显示画面缩放比例，和/或旋转角度。控制器250需要对显示画面进行调整，例如，在显示器275顺时针转动90度的过程中，控制显示画面逆时针转动90度，且保持显示器275与显示画面转动过程同步运行，达到始终正向显示画面的目的。
本申请中，通过在画质层对显示画面进行调整，即仅对视频播放画面进行调整，因此调节的灵活性和效率会大大增加。画质层上的调整对于显示画面的调整不受所播放视频资源文件的来源限制，可以对本地磁盘里的视频文件进行调节，也可以对DLNA推送到显示设备200的视频文件，以及对DMS共享出来的视频文件进行调节。此外，画质层上的调节还可以在不影响UI层画面的基础上，对显示画面进行更进一步的调节。
例如，控制器250还可以对显示画面进行更细致的调整，包括旋转操作、缩放操作等。其中，旋转操作是为了适应显示器275的旋转而进行的调整，缩放操作是为了适应显示器275在旋转过程中宽高变化而进行的调整。实际应用中，旋转操作和缩放操作可以同时进行，也可以先进行旋转操作，后进行缩放操作。
在一种实现方式中，如图9所示，对于显示画面的缩放操作，所述控制器250被进一步配置为执行以下步骤：
S311：获取所述视频媒体资源对应的当前显示窗口位置。
S312：结合当前旋转状态，确定目标显示窗口位置；
S313：比对所述目标显示窗口位置与所述当前显示窗口位置，生成宽高变形量；
S314：生成缩放步长，所述缩放步长为根据所述宽高变形量与所述旋转组件的转动速度计算获得的单位时间宽高缩放量；
S315：按照所述缩放步长调整显示画面窗口的宽高数值。
本申请提供的技术方案中，所述当前显示窗口位置和目标显示窗口位置是指对应于显示器275旋转状态，显示器275旋转前后的画面显示窗口位置。例如，显示器275需要从横屏状态旋转到竖屏状态的过程中，横屏状态下对应画质层显示播放视频的画面位置即为当前显示窗口位置；而在旋转后显示器275竖屏状态下对应画质层显示播放视频的画面位置即为目标窗口位置。同理，在显示器275需要从竖屏状态旋转到横屏状态的过程中，竖屏状态下对应画质层显示播放视频的画面位置即为当前显示窗口位置；而在旋转后显示器275横屏状态下对应画质层显示播放视频的画面位置即为目标窗口位置。
本实施例中，为了使得显示画面在显示器275的旋转过程中，始终能够较多地填充显示器275的显示区域，保证显示画面的质量，可以在对显示画面进行旋转的过程中，同时对显示画面进行等比例缩放。
具体的，可以在播放媒资画面后，根据旋转角度以及显示器275的屏幕尺寸特点，确定目标显示窗口位置。例如，需要从横屏状态切换至竖屏状态，则提取的旋转角度为顺时针90度，从而确定预定目标窗口位置为竖屏状态下播放区域对应的位置。
在确定目标显示窗口位置后，可以通过比对目标显示窗口位置与当前显示窗口位置，确定显示窗口的宽高变形量。例如，65寸的显示器尺寸为1440：810，在横屏状态下显示竖向媒资，则显示画面的高度小于或等于显示器275的高度，即小于或等于810mm，而在竖屏状态下显示竖向媒资则可以小于或等于1440mm的高度(横屏状态下显示器的宽度)，因此可以确定显示画面高度变形量为1440-810＝630mm。同理，按照竖向媒资的宽高比可以计算出宽度变形量。
在确定宽高变形量后，可以根据宽高变形量与旋转组件276的转动速度计算获得的单位时间宽高缩放量，即生成缩放步长。例如，显示器275要在15s从横屏状态旋转到竖屏状态，则高度缩放步长为630/15＝42mm/s。同样，根据宽度的变形量，也可以计算出宽度的缩放步长。
分别确定显示画面高度和宽度的缩放步长后，可以按照缩放步长同时调整显示画面窗口的宽高数值。从而在显示器275旋转至目标状态时，显示画面恰好充满显示器275的显示区域，提高用户体验。
为了获得更好的显示效果，在按照缩放步长同时调整显示画面窗口的宽高数值的步骤中，控制器250还可以被配置为以下程序步骤：在当前显示窗口中 定位缩放基点坐标；并且以所述缩放基点坐标为基准，按照所述缩放步长同步调整显示画面窗口的宽高数值。
其中，缩放基点可以根据显示窗口的形状和调节方式进行定位，例如可以选择显示窗口的中心点作为缩放基点，这样，在显示画面旋转前后，基点的位置是固定不变的。还可以窗口边界四个顶点中的一个作为缩放基点，例如左上顶点等。
在一种实现方式中，如图10所示，对于显示画面的旋转操作，所述控制器250被进一步配置为执行以下步骤：
S321：生成画面旋转方向；
可以根据显示器275的旋转方向，确定显示画面的旋转方向，其中，所述画面旋转方向与所述显示器的旋转方向相反。例如，显示器275需要顺时针旋转90度，以从横屏状态切换到竖屏状态。相应的画面旋转方向为逆时针旋转。
S322：比对所述目标显示窗口位置与所述当前显示窗口位置，生成角度变形量。
在确定旋转方向后，可以根据目标显示窗口位置与当前显示窗口位置，生成角度变形量。例如，目标显示窗口位置为竖屏状态下的显示位置；当前显示窗口位置为横屏状态下的显示位置，则角度变形量为90度。
S323：生成旋转步长。
在生成角度形变量后，同样结合显示器275的转动速度，计算旋转步长。所述旋转步长为根据所述角度变形量与所述旋转组件的转动速度计算获得的单位时间角度转动量。例如，旋转过程从横屏状态切换到竖屏状态消耗时间为15s，则旋转步长为90/15＝6度/s，即在旋转过程中，每秒显示画面转动6度，以使 得显示器275和显示画面保持同步旋转。
S324：按照所述旋转步长以及画面旋转方向，调整显示画面窗口的显示方向。
在计算旋转步长后，则可以按照所述旋转步长以及画面旋转方向，调整显示画面窗口的显示方向。例如，显示器275每秒顺时针转动6度，同时显示画面逆时针旋转6度，从而使显示画面始终保持正向的状态。
需要说明的是，为了适应多种不同的视频资源，显示器275的状态可能不仅限于横屏状态和竖屏状态两种，还有可能根据播放需要保持在多种倾斜状态等。因此，所述当前显示窗口位置和目标显示窗口位置并不局限于上述两种情况，还可能是任意两个倾斜角度下的旋转过程。因此，根据上述旋转方式所能够联想到的横竖屏旋转、横斜屏旋转、竖斜屏旋转以及斜斜屏旋转都属于本申请的保护范围。
在上述实施例中，可以根据旋转组件276驱动显示器275转动的速度，对显示画面的旋转操作进行控制。由于一个显示设备200在初始调试后，旋转组件276的转动速度由驱动电机确定，可以是保持不变的，因此对于所有旋转过程，都可以通过固定的旋转速度确定旋转参数。因此，上述计算旋转参数的过程最简单，也最便于对旋转操作进行控制。
但在个别情况下，例如旋转组件276随使用时间的延长，出现累积误差时，旋转组件276的旋转速度会发生变化，为了适应旋转速度的变化，在一种实现方式中，所述旋转组件276上设置有角度回调接口，角度回调接口可以通过角度传感器实时检测所述旋转组件276所转动的角度，从而确定显示器275旋转的过程中，任意时刻对应的姿态。还可以通过显示器275上设置重力加速度传 感器，在显示器275旋转的过程中，通过检测重力传感器在空间坐标系(x，y，z)3个方向上的信息，获取显示器275任意时刻对应的姿态。再根据检测的数据实时调整显示画面，即如图11所示，所述控制器被进一步配置为：
S231：监听所述旋转组件的角度传感器和/或所述重力加速度传感器，实时获取显示器的角度数据；
S232：根据所述角度数据同步计算显示画面的旋转参数。
实际应用中，如图12所示，控制器250可以在控制显示器275旋转的过程中，通过监听android标准的角度回调接口，启动Orientation Event Listener程序获得显示器275的旋转角度，从而实时计算目标窗口的位置和需要旋转角度，实现跟随显示器275进行旋转的效果。
上述实施例中，监听的角度回调接口不仅局限于Android标准的角度回调接口，实际应用时可以依据显示设备200的操作系统调用相对应的其他角度回调接口。还可以为控制器250根据重力加速度传感器等sensor的x，y，z方向信息，按照设定的规则生成的角度回调接口。
示例的，在实时计算目标窗口的位置和需要旋转角度的步骤如下：
如图13所示，视频显示区域Rect是由4个点组成的长方形区域，每个点的坐标是该点在屏幕上的坐标。以屏幕左上角为原点，Rect指定点1和点4即可确定位置，点1是(left，top)，点4是(right，bottom)。
设置给画质层Surface View的参数包括缩放比例scale X和scale Y以及旋转角度rotate。其中，scale X，scale Y可以使用Rect的right和bottom位置，记录视频窗口的宽和高，分别计算视频窗口的当前位置oldRect和目标位置newRect，根据等步长原理逐步增加显示区域的宽高，直到目标位置。其具体算 法如下：
Rect oldRect＝new Rect(0,0,oldWidth,oldHeight)；
Rect newRect＝new Rect(0,0,newWidth,newHeight)；
float defWidth＝(newWidth–oldWidth)/90；
float defWidth＝(newWidth–oldWidth)/90；
float tempWidth＝oldWidth+defWidth×rotate；
float tempHeight＝ildHeight+defHeight×rotate；
flocat scaleX＝tempWidth/mBaseWidth；
flocat scaleY＝tempHeight/mBaseHeight；
其中，mBaseWidth和mBaseHeight是基准宽高，用来计算scale X和scale Y。
由以上技术方案可知，本申请提供的显示设备能够在画质层对视频播放画面进行调整，从而实现自动旋转显示器275，并且在显示器275旋转的过程中，显示画面也实时进行旋转，因此可以使显示画面始终保持正向的状态，降低电视旋转过程对观影体验的影响。
基于上述显示设备200，本申请还提供一种显示画面旋转适配方法，所述显示画面旋转适配方法被配置在控制器250中，用于对旋转过程进行控制，具体包括：
响应于显示设备的视频媒体资源播放动作，检测所述显示器的当前旋转状态；
