在一些实施例中，将显示设备作为显示端与外设设备进行交互时，外设设备仅作为输入设备。显示设备与外设设备的交互内容仅呈现在显示设备中，使得显示设备的内容相对封闭，而显示设备并未与外设设备进行信息共享，使得外设设备在交互过程中不会产生相应变化，这将导致交互场景中内容呈现形式较为单一，用户体验感不高。
为便于用户在利用显示设备进行游戏、唱歌等娱乐交互场景时，能够烘托气氛，提高用户体验，本发明实施例提供一种显示设备，可在播放电视画面、游戏或唱歌等娱乐交互场景下，控制外设设备的显示颜色，使之可以随着画面颜色的变化而变化。
为实现外设设备的颜色变化，与显示设备进行交互的外设设备可选用能够发光变色的设备，例如，可变颜色的灯泡、LED灯条、灯带、氛围灯等。外设设备的显示颜色随显示设备的画面的颜色变化而变化，可以烘托显示内容的氛围，增加显示内容的呈现形式，提升用户使用显示设备的体验。
图6为根据一些实施例的显示设备的结构框图。为此，本发明一些实施例提供一种显示设备200，参见图6，包括显示器275和与显示器275连接的控制器250。显示器275被配置为显示画面。显示设备可以与外设设备201连接，外设设备201为可发光变色的设备，被配置为在显示设备的显示器上呈现该外部设备对于标识或图标等，并且能够根据外部设备的不同而呈现不同的颜色。控制器250用于将显示器275中显示的画面的颜色实时同步至外设设备201，使得外设设备201的显示颜色与显示器显示的画面的颜色同步更新，该画面可以是显示器显示的任何画面，诸如视频、供用户操作的用户界面、或其结合。显示设备可以通过接口(未图示)与外设设备连接。所述接口可以包括任何合适的外部装置接口，例如，网络接口，诸如socket接口，例如显示设备电视作为socket服务器，外设设备智能灯作为socket客户端，开机后客户端可以连接到服务器，服务器可以向客户端进行颜色值传输；USB接口，使得显示设备通过USB传输协议与USB外设设备进行通信；以及蓝牙接口，通过蓝牙传输协议进行颜色值传输。
为更加准确地利用外设设备呈现画面的颜色，提高气氛烘托的效果，在一些实施例中， 同时与显示设备交互的外设设备可为多个。例如，可设置四个外设设备，每个外设设备与显示设备进行连接，连接方式可为有线连接或无线连接，保证在同一局域网中即可。
在采用无线连接方式时，将显示设备连接到路由器，路由器给显示设备分配局域网IP；再将外设设备连接到路由器，路由器给外设设备分配局域网IP。通过路由器即可实现显示设备与每一个外设设备在同一个网段的连接。在一些实施例中，可采用蓝牙连接。显示设备可以通过扫描获得连接的所有外设设备。
图7为根据一些实施例的设备列表的示意图。参见图7，显示设备在进行扫描时，将扫描到的每个外设设备显示在设备列表中。若扫描到四个外设设备，则将四个外设设备的名称显示在设备列表中。
基于设备列表，还可对每个外设设备的名称进行修改，也可将其他与颜色呈现不相关的设备在设备列表中删除。
在一些实施例中，多个外设设备可设置在显示设备的显示器的周围(如图9所示)，以设置四个外设设备为例，第一个外设设备201a设置在显示器的上侧，第二个外设设备201b设置在显示器的下侧，第三个外设设备201c设置在显示器的左侧，第四个外设设备201d设置在显示器的右侧。
显示器275周围设置的四个外设设备，可分别呈现画面的对应位置所呈现的颜色，即利用第一个外设设备201a呈现画面上端的颜色；利用第二个外设设备201b呈现画面下端的颜色；利用第三个外设设备201c呈现画面左端的颜色；利用第四个外设设备201d呈现画面右端的颜色。
每个外设设备对应显示器中画面的相应位置，使得每个外设设备201的显示颜色均可与画面的对应位置的颜色同步更新，提高外设设备的显示颜色的效果。
目前针对显示设备画面采用的是直接提取画面RGB颜色的方法，RGB由三个通道表示一幅图像，分别为红色(R)，绿色(G)和蓝色(B)。通过这三个颜色组合形成所有的其他颜色。组合后的颜色与这三个分量是高度相关的，所以连续变换颜色时并不直观。RGB颜色另一个问题是这三个分量都与亮度密切相关，即只要显示设备周围亮度发生改变，三个分量均会随之相应地改变，但是RGB参数中并没有用于表达亮度的参数。因此通过RGB方式提取的颜色值同步给发光外设的显示后差异较大，从而影响了显示效果。
基于此，本申请实施例提供一种外设设备颜色随画面颜色变化的方法，采用提取画面HSL值的方式，将画面HSL值输出至与显示设备绑定的外设设备，由于HSL值中存在表征亮度的参数亮度L，因此，相比于通过RGB方式提取的颜色值，HSL值更能够直观的表现画面颜色。图8为根据一些实施例的外设设备颜色随画面颜色变化的方法的流程图。本发明实施例提供的一种显示设备，参见图8，其配置的控制器250在执行外设设备颜色随画面颜色变化的方法时，被配置为执行下述步骤：
S1、将画面划分为若干颜色提取区域。
由于与显示设备同时交互的外设设备可为多个，每个外设设备的显示设备仅会跟随画面的对应位置的颜色变化，因此，为便于准确确定每个外设设备可呈现的画面对应位置的颜色，可将画面划分成多个颜色提取区域，颜色提取区域用于提供画面相应位置所呈现的颜色。
在划分区域时，在一些实施例中，控制器在执行将显示器中显示的画面划分为多个颜色提取区域，被进一步配置为执行下述步骤：
获取所述显示器呈现的画面；
按照预设划分规则，对所述画面进行区域划分，得到多个颜色提取区域，所述预设划分规则包括颜色提取区域与画面之间的占比关系。
由于一个显示设备的显示画面一般都会有多重颜色，提取整个显示设备的面颜色的值控制外设设备的颜色，一定会出现颜色不一致问题，也不利于控制多个外设设备，因此需要对画面进行区域划分。控制器获取显示器呈现的画面，将画面按照预设划分规则划分成多个颜色提取区域。预设划分规则可为根据颜色提取区域与画面之间的占比关系的画面进行划分。图9为根据一些实施例的颜色提取区域的示意图。参见图9，若需要获取四分之一的画 面，则可以在画面中任意部分提取画面面积为整个画面面积四分之一的颜色提取区域，如图9中所示的取色区块P1，作为一种实施方式，也可以在显示画面中截取不靠近显示屏周围边框的位置，如图10所示的取色区块P2和取色区块P3，其中，取色区块P1、取色区块P2以及取色区块P3可以重合选取，通过获取显示设备电视屏幕的分辨率进行计算每一个取色区块的定点坐标。作为另一种实施方式，也可以将画面划分成互不重合的多个颜色提取区域，多个颜色提取区域的总和可小于或等于画面所呈现的完整区域，如图11所示，将画面划分成四个不重合的颜色提取区域，四个颜色提取区域的位置可分别位于画面的上、下、左、右四个位置，第一个取色区块A1位于画面的上侧，第二个取色区块A2位于画面的下侧，第三个取色区块A3位于画面的左侧，第四个取色区块A4位于画面的右侧。
在一些实施例中，颜色提取区域划分完成之后，建立划分出的每个颜色提取区域与其相对应的外设设备的绑定关系，所述外设设备的数量与所述颜色提取区域的数量相同，使得颜色提取区域与外设设备呈现一对一的绑定关系，实现由一个外设设备接收一个颜色提取区域的颜色，以便于外设设备可以显示对应区域位置的画面的颜色，避免出现混乱，以呈现不同的外设设备显示不同的颜色的效果。
在一些实施例中，颜色提取区域划分完成之后，建立划分出的每个颜色提取区域与其相对应的外设设备的绑定关系，所述外设设备的数量与所述颜色提取区域的数量也可以不相同，一个颜色提取区域可以绑定多个外设设备，多个颜色提取区域也可以绑定一个外设设备，而非一对一的绑定关系，实现多个外设设备接收一个颜色提取区域的颜色，或者一个外设设备接收多个颜色提取区域的颜色，可以根据实际的应用场景进行选择，从而呈现出不同的外设设备根据预设规则显示不同的颜色的效果。
在将外设设备与颜色提取区域绑定关系时，通过触发设备列表中的目标外设设备名称，将对应的外设设备呈现闪烁状态，以准确确定将要进行绑定的设备为一个或者多个。而后，可基于用户的个性化设置，将该闪烁的外设设备与相对应的颜色提取区域建立绑定关系。为便于外设设备呈现画面的颜色的一致性，可以按照设定位置相同的规则建立外设设备与颜色提取区域的绑定关系。
在一些实施例中，外设设备的设置位置与颜色提取区域的位置进行绑定，例如，将设置在显示器上侧的第一个外设设备201a与位于画面左上角的取色区块P1对应，同时将该外设设备201a与位于画面左下或者右上的取色区块P2和P3对应。
在一些实施例中，外设设备的设置位置与颜色提取区域的位置一一对应，例如，将设置在显示器上侧的第一个外设设备201a与位于画面上侧的第一个取色区块A1对应，将设置在显示器下侧的第二个外设设备201b与位于画面下侧的第二个取色区块A2对应，将设置在显示器左侧的第三个外设设备201c与位于画面左侧的第三个取色区块A3对应，将设置在显示器右侧的第四个外设设备201d与位于画面右侧的第四个取色区块A4对应。
S2、获取所述颜色提取区域中目标颜色提取区域所呈现画面内容的HSL值。
划分出的颜色提取区域用于为对应的外设设备提供显示的颜色，因此，可对每个颜色提取区域中所呈现的画面内容进行颜色提取，确定每个颜色提取区域对应的HSL值。
在确定HSL值时，可直接从每个颜色提取区域中进行提取，还可先获取当前显示器中显示的画面(即先截图)，再从截图中提取每个颜色提取区域的HSL值。
根据一些实施例提供了提取色彩特征值的一种方法。在一些实施例中，采用直接提取时，控制器在执行获取所述颜色提取区域中目标颜色提取区域所呈现画面内容的HSL值，被进一步配置为执行下述步骤：
选定所述颜色提取区域中的目标颜色提取区域；
参见图11中的颜色提取区域划分方式，在一些实施例中，可以以取色区块P1作为目标颜色提取区域，或者以取色区块P2作为目标颜色提取区域，亦或者以取色区块P3作为目标颜色提取区域。
计算所述目标颜色提取区域中所呈现画面内容的的H颜色通道值、S颜色通道值和L颜色通道值；
提取所述H颜色通道值、S颜色通道值和L颜色通道值作为每个所述目标颜色提取区域对应的HSL值。
由于每个外设设备仅会呈现与其产生绑定关系的颜色提取区域所呈现画面内容的颜色，因此，控制器可直接提取目标颜色提取区域所呈现画面内容的H颜色通道值、S颜色通道值和L颜色通道值。H颜色通道值、S颜色通道值和L颜色通道值分别表征HSL色彩模式对色相(Hue)、饱和度(Saturation)、亮度(Lightness)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色。
其中，H颜色通道值色相(Hue)是色彩的基本属性，代表的是人眼所能感知的颜色范围，这些颜色可以表示为分布在一个平面的色相环上，取值范围是0°到360°的圆心角，每个角度可以代表一种颜色。色相环上的六大主色360°/0°红、60°黄、120°绿、180°青、240°蓝、300°洋红，它们在色相环上按照60°圆心角的间隔排列。S颜色通道值饱和度(Saturation)是指色彩的纯度，饱和度越高色彩越纯越浓，饱和度越低则色彩变灰变淡，可以由取值范围0％至100％表示，数值越大，颜色中的灰色越少，颜色越鲜艳，纯度是黑灰白到鲜艳的排列，给出0-9个级差。L颜色通道值亮度(Lightness)指的是色彩的明暗程度，亮度值越高，色彩越白，亮度越低，色彩越黑，可以以由取值范围0％至100％表示，数值越小，色彩越暗，越接近于黑色；数值越大，色彩越亮，越接近于白色。
每个目标颜色提取区域均对应一个HSL值为(H，S，L)，例如，取色区块P1对应的HSL值为(H1，S1，L1)，取色区块P2对应的HSL值为(H2，S2，L2)，取色区块P3对应的HSL值为(H3，S3，L3)。
在一些实施例中，通过以下方式计算各个取色区块对应的HSL值。
在一些实施例中，针对取色区块的HSL值中的色相H，按公式(1)计算。
Figure PCTCN2022102403-appb-000001
其中，N为对取色区块的总取样数量，是正整数；m为在色相环范围中的取样点的数量，是正整数；h i为第i个取样点的色相值，1≤i≤m；n i为在取色区块中N个总取样数量之中与第i个取样点具有相同的色相值的取样数量，被称为返回数值。
在一些实施例中，针对色相的计算，取色区块P1中总取样数量N为10000；将色相值h的取值范围定义为0-360°，在该取值范围内，在表示色相的色相环上设置8个取样点(即，m＝8)，即第一至第八取样点，分别在如下8个角度上取样：第一取样点对应的h 1为280°、第二取样点对应的h 2为320°、第三取样点对应的h 3为0°、第四取样点对应的h 4为40°、第五取样点对应的h 5为80°、第六取样点对应的h 6为120°、第七取样点对应的h 7为180°以及第八取样点对应的h 8为240°；按上述取样点在取色区块P1中的返回数值表示为n 1至n 8，其中，第一至第八取样点各自的返回数值n 1至n 8分别为1、20、9351、338、86、66、60以及78。
将以上h 1至h 8、n 1至n 8、以及N为10000的数值代入公式(1)计算如下：
[(280*1)+(320*20)+(0*9351)+(40*338)+(80*86)+(120*66)+(180*60)+(240*78)]/10000，算得的平均值即为该取色区块P1的色相值H1。
在设置取样点时，不一定是从0°开始取样，可以从色相圆周角度上任意角度值开始取样，在本申请一些实施例中给出了其中的一种取样方式，且可以为在色相圆周角度上均匀取样或非均匀取样；取样点的数量也可以根据实际需要进行选取，本申请实施例中不做具体限制。
在一些实施例中，针对取色区块的HSL值中的饱和度S，按公式(2)计算。
Figure PCTCN2022102403-appb-000002
其中，N为对取色区块的总取样数量，是正整数；m为在饱和度范围中的取样点的数量，是正整数；s i为第i个取样点的饱和度值，1≤i≤m；n i为在取色区块中N个总取样数量之中与第i个取样点具有相同的饱和度值的取样数量，被称为返回数值；smax是饱和度取值范围的上限。
在一些实施例中，针对饱和度的计算，取色区块P1中总取样数量N为10000，将饱和度取值范围定义为0-63，即，s max为63，在该取值范围内，设置8个取样点(即，m＝8)，即第一至第八取样点，其中，第一至第八取样点各自对应的饱和度值s 1-s 8分别为2、9、17、25、33、41、51以及62；按上述取样点在取色区块P1中的返回数值表示为表示为n 1至n 8，其中，第一至第八取样点各自的返回数值n 1至n 8分别为3383、43、36、90、133、106、26以及6183。
将以上s 1至s 8、n 1至n 8、s max为63以及N为10000的数值代入公式(2)计算如下：
[(2*3383)+(9*43)+(17*36)+(25*90)+(33*133)+(41*106)+(51*26)+(62*6183)]/(63*10000)，算得的平均值即为该取色区块P1的饱和度S1。
在设置取样点时，不一定是按照本申请实施例提供的方式取样，可以根据实际试验操作进行选取，从取值范围0-63内任意取样，在本申请一些实施例中给出了其中的一种取样方式，且可以为在取值范围0-63内均匀取样或非均匀取样；取样点的数量也可以根据实际需要进行选取，本申请实施例中不做具体限制。
在一些实施例中，针对取色区块的HSL值中的亮度L，按公式(3)计算。
Figure PCTCN2022102403-appb-000003
其中，N为对取色区块的总取样数量，是正整数；m为在亮度范围中的取样点的数量，是正整数；l i为第i个取样点的亮度值，1≤i≤m；n i为在取色区块中N个总取样数量之中与第i个取样点具有相同的亮度值的取样数量，被称为返回数值；l max是亮度取值范围的上限。
在一些实施例中，针对亮度的计算，取色区块P1中总取样数量N为10000，使用获取L颜色通道值的数据列表au2LumaHist值计算，将亮度取值范围定义为0-255，即，l max为255，在该取值范围内均匀取样，设置均匀分配32个取样点(即，m＝32)，使用每个取样点的亮度值及其在取色区块P1中的返回数值按公式(3)计算该取色区块的亮度，算得的平均值即为该取色区块P1的亮度L1。
同理，按照上述方式可以计算出取色区块P2的H2、S2和L2，以及，取色区块P3的H3、S3和L3。因此，即可得到取色区块P1对应的HSL值为(H1，S1，L1)，取色区块P2对应的HSL值为(H2，S2，L2)，取色区块P3对应的HSL值为(H3，S3，L3)。
S3、将每个所述目标颜色提取区域的HSL值发送至与所述目标颜色区域所绑定的外设设备，由所述外设设备呈现所述HSL值对应的颜色。
在确定出每个颜色提取区域的HSL值后，即可将该HSL值发送至对应的外设设备进行显示。每个颜色提取区域与外设设备存在相对应的绑定关系，因此，控制器可将每个颜色提取区域的HSL值基于绑定关系发送至对应的外设设备。
在一些实施例中，若所述外设设备支持HSL值色彩呈现，则将每个所述目标颜色提取区域的HSL值直接发送至所述外设设备。
例如，将第一个取色区块P1对应的HSL值为(H1，S1，L1)发送至第一个外设设备201a，由第一个外设设备201a呈现HSL值(H1，S1，L1)对应的颜色。将第二个取色区块P2对应的HSL值(H2，S2，L2)发送至第二个外设设备201b，由第二个外设设备201b呈现HSL值(H2，S2，L2)对应的颜色。将第三个取色区块P3对应的HSL值C3(H3，S3，L3)发送至第三个外设设备201c，由第三个外设设备201c呈现HSL值(H3，S3，L3)对应的颜色。
若一个取色区块对应于多个外设设备，则将一个取色区块的HSL值发送至多个外设设备，例如，将取色区块P1对应的HSL值为(H1，S1，L1)发送至第一个外设设备201a的同时，将取色区块P1对应的HSL值为(H1，S1，L1)发送至第二个外设设备201d。
在一些实施例中，若所述外设设备不支持HSL值色彩呈现，则将每个所述目标颜色提取区域的HSL值转换成RGB值后，将所述RGB值发送至所述外设设备。
HSL值转换为RGB值，为目前常见的技术，本申请实施例中不做赘述。
控制器在将RGB均值发送至对应的外设设备时，可先将RGB均值打包成网络包的形式进行发送。外设设备接收到网络包，进行解析，得到对应的颜色值，并将该颜色进行显示，改变该外设设备的显示颜色。
在一些实施例中，控制器每隔100毫秒获取一次指定颜色提取区域的HSL值，再由外设设备显示HSL值对应的颜色，使得画面与外设设备共同所显示的颜色呈现渐变颜色的效果，这样可以保证画面与外设设备的显示颜色同步显示，实现外设设备的显示颜色随画面的改变而改变。
根据本发明一些实施例提供了一种显示设备及其控制方法。显示设备包括显示器；接口；与所述显示器和接口连接的控制器，所述控制器控制显示设备通过接口与外设设备连接，所述外设设备被配置为呈现不同的颜色；以及将所述显示器中显示的画面的颜色按区域同步至所述外设设备。为了将所述显示器中显示的画面的颜色按区域同步至所述外设设备，控制器将用面划分为若干颜色提取区域，获取所述颜色提取区域中目标颜色提取区域所呈现画面内容的HSL值；以及将每个所述目标颜色提取区域的HSL值发送至与所述目标颜色区域所绑定的外设设备，由所述外设设备呈现所述HSL值对应的颜色。通过本申请实施例给出的方法获取颜色值，能够控制外设的亮度，性能更好，解决了相关技术中提取颜色在外设设备上的准确度问题，以及外设设备颜色改变是否与显示设备显示画面同步的问题。
根据本申请的一些实施例，显示设备也可以作为标准的蓝牙设备，能够被外部设备(诸如各种其他蓝牙设备)扫描或扫描外部设备并进行配对与连接。但是，目前存在一些蓝牙设备能够主动对显示设备等支持蓝牙技术的设备发起连接。这些蓝牙设备在发起连接请求时，显示设备会弹出蓝牙配对连接的信息提示。如果显示设备已经连接了蓝牙设备，或者当前正在播放内容等，这种信息提示会干扰显示设备正常播放的内容，也会影响用户的使用体验。
根据本申请一些实施例，还提供了能够防止蓝牙设备干扰的显示设备及方法，以解决未配对的蓝牙设备对显示设备的正常使用产生干扰的问题。
以显示设备200是手机，蓝牙设备是蓝牙耳机为例，如果蓝牙耳机m扫描到用户的手机，那么会立刻主动地向该手机发送配对请求。如图12所示，手机接收到配对请求后，会在当前的显示内容上弹出一个配对提示页面，在该配对提示页面上显示“是否与该蓝牙耳机m配对”的提示和“配对”、“取消”等控件。如果该手机已经连接了用户自己的蓝牙耳机，而用户又不想要更换蓝牙耳机m，那么手机上当前显示的配对提示页面就会影响用户当前正在观看的内容。
为了解决上述未配对的蓝牙设备对于显示设备200的干扰问题，本申请实施例中的显示设备200，可以提供蓝牙可见性开关，当用户不希望显示设备200连接蓝牙设备时，可以关闭该蓝牙可见性开关；或者，当显示设备200已经连接了一个蓝牙设备，而用户不希望其他蓝牙设备连接显示设备200时，可以关闭该蓝牙可见性开关。当蓝牙可见性开关关闭后，显示设备200将不会被蓝牙设备扫描到，进而蓝牙设备也不会主动地向显示设备200发送配对请求。这样，显示设备200可以正常被使用或者显示内容，不会被蓝牙设备的配对提示而干扰。
在本申请一些实施例中，显示设备200可以内置蓝牙组件和wifi组件，其中：蓝牙组件具备蓝牙连接功能，用于和其他设备建立蓝牙连接；wifi组件用于建立wifi连接，具体用于和移动终端(例如，蓝牙设备)建立同一局域网内的socket连接。socket连接是WIFI连接的其中一种连接方式，能够传输比蓝牙传输更大的数据量。
显示设备200在首次开机或者恢复出厂默认设置后，会开启蓝牙功能并显示导航配置界面，在本申请一些实施例中，首次开机指令具体是指显示设备200出厂后的首次开机指令，或者恢复出厂默认设置后的首次开机指令。
在本申请的一些实施例中，显示设备200响应于首次开机指令后，自动开启蓝牙功能，显示设备200的蓝牙状态由待机态(standy)转换到广播态(Advertising)，通过广播的方式，发送携带所述显示设备200的厂商信息和连接方式的广播包。
在一些实施例中，显示设备200发送的广播包的格式，包括有效数据部分(Significant part)和无效数据部分(Non-significant part)，其中，有效数据部分是由N个AD结构(Structure)组成，每个AD Structure的格式都是：Length(长度)|AD Type(数据类型)|AD Data(数据)。例如，在本申请一些实施例中，定义的数据类型为05ff，数据为5d 00 04 00，表示携带的厂商信息和连接方式。
显示设备200按照上述广播包的格式，不断发送广播包。其中，显示设备200按广播间隔不断的发送广播包(即广播数据)。蓝牙设备进入扫描态，发送扫描请求，持续的监听环境中的广播包，当监听到广播包后(即接收到显示设备200发送的扫描响应)，通过解析广播包(即扫描响应携带的广播包)中的内容，确认厂商信息和连接方式后，根据厂商信息确定需要进行蓝牙连接的显示设备200，并根据该连接方式向显示设备200发送蓝牙连接请求，显示设备200收到蓝牙连接请求后，建立与该连接方式对应的蓝牙连接。
在一些实施例中，蓝牙设备发送设备发现广播，通过散发广播消息来搜寻附近开启蓝牙功能的设备。显示设备200在接收到蓝牙设备所发送的广播消息之后，响应于该设备发现广播，并向所述蓝牙设备发送应答信息，其中，所述应答消息用于表征所述显示设备200是否支持通过所述蓝牙设备进行控制。
针对蓝牙可见性开关的设置过程，根据一些实施例的显示设备200的控制器250可以被配置为：响应于用户在所述显示设备的蓝牙设置页面上的输入而产生蓝牙开关指令；响应于所述蓝牙开关指令，控制蓝牙可见性开关的状态；响应于所述蓝牙可见性开关的状态为关闭，控制所述显示设备处于不可被扫描到的状态，使得所述显示设备不被蓝牙设备扫描到；以及响应于所述蓝牙可见性开关的状态为开启，控制所述显示设备处于可以被扫描到的状态，使得所述显示设备可以被蓝牙设备扫描到。
本申请实施例的显示设备200可以将蓝牙可见性开关显示在蓝牙设置页面上，为了避免蓝牙设备对于显示设备200干扰，用户可以在蓝牙设置页面上将蓝牙可见性开关设置为关闭，显示设备200响应于用户的设置而调用蓝牙可见性关闭程序来关闭蓝牙可见性开关，使得显示设备200不会被蓝牙设备扫描到。在一些实施例中，在蓝牙设置页面上，蓝牙可见性开关可以具体显示为可左右移动的开关控件，开关控件向右移动时，表示蓝牙可见性开关开启；开关控件向左移动，表示蓝牙可见性开关关闭。
前述实施例中，用户可以通过实体遥控器或者虚拟遥控器等对显示设备200进行设置，例如按下方向键控制显示设备200页面上的焦点移动，按下确认键选择焦点所在的选项或者内容等。用户也可以通过向能提供语音服务的显示设备200输入语音内容，进而向显示设备200输入控制指令，例如输入语音内容“打开蓝牙设置页面”等。
如果用户需要显示设备200连接蓝牙设备，或者需要显示设备200更换其他的蓝牙设备进行连接，则用户可以将蓝牙可见性开关开启。用户可以在蓝牙设置页面上将蓝牙可见性开关设置为开启，显示设备200响应于用户的设置而调用蓝牙可见性开启程序来开启蓝牙可见性开关，使得显示设备200可以被蓝牙设备扫描到。当蓝牙可见性开关开启后，显示设备200处于可以被扫描的状态，从而可以被蓝牙设备扫描到，进而蓝牙设备也会主动地向显示设备200发送配对请求。这样，用户就可以根据自己的需求，控制显示设备200与目标蓝牙设备连接。
在蓝牙可见性开关开启之后，可以扫描到显示设备200的蓝牙设备可能是已经与显示设备200配对过的蓝牙设备，也可能是未与显示设备200进行配对的蓝牙设备。
对于已经与显示设备200配对过的蓝牙设备，显示设备200已经保存过蓝牙设备的设备信息，蓝牙设备中也已经保存过显示设备200的设备信息。因此，当蓝牙设备扫描到显示设备200后，不必再次向显示设备200发送配对请求，可以直接发送连接请求。显示设备200根据该连接请求直接与蓝牙设备连接。
在上述显示设备200与已配对蓝牙设备连接的过程中，显示设备200的控制器250可以被配置为：首先，响应于蓝牙可见性开关的开启，控制显示设备200接收已配对蓝牙设备发送的连接请求；以及响应于连接请求，控制显示设备200与已配对蓝牙设备连接。
而对于未配对过的蓝牙设备，由于显示设备200未保存蓝牙设备的设备信息，该蓝牙设备中也未保存过显示设备200的设备信息，因此，当未配对蓝牙设备扫描到显示设备200后，需要先向显示设备200发送配对请求。在显示设备200同意与该未配对蓝牙设备配对后，该未配对蓝牙设备才能与显示设备200配对进行连接。
在一些实施例中，未配对蓝牙设备在向显示设备200发送配对请求后，显示设备200不会主动与未配对蓝牙设备进行配对，而是显示配对提示页面，用以提示用户是否需要将显示设备200与该未配对蓝牙设备进行配对。
参见图13，图13为根据一些实施例的配对提示页面的示意图。在该配对提示页面上显示了“蓝牙配对请求”和“与手机连接，请确保手机上显示密码：967919”等提示，还显示了“配对”和“取消”等选项。用户如果确定了待配对的手机上显示了配对密码为：967919，就可以选择“配对”选项，由此向显示设备200输入配对指令，控制显示设备200与手机配对。
通常，显示设备200与未配对蓝牙设备配对完成后，即可立即与该未配对蓝牙设备进行连接。此时，未配对蓝牙设备就会变为已配对蓝牙设备。
在显示设备200显示了配对提示页面后，用户如果发现手机上显示的配对密码错误，或者不想与该手机进行配对，那么用户也可以选择“取消”选项，由此向显示设备200输入取消指令，控制显示设备200继续显示正常内容。此时，显示设备200仍保持当前的蓝牙连接状态，并不会与该手机进行配对。
在上述显示设备200与未配对蓝牙设备连接的过程中，显示设备200的控制器250还可以被配置为：响应于蓝牙可见性开关的开启，控制显示设备200接收未配对蓝牙设备发送的配对请求；响应于配对请求，控制显示器260显示配对提示页面，以提示用户可以进行显示设备200与未配对蓝牙设备的配对；响应于用户对提示页面上选项“配对”的选择而产生配对指令，响应于配对指令而控制显示设备200与未配对蓝牙设备进行配对；以及响应于配对完成，控制显示设备200与已配对蓝牙设备进行连接。
前述实施例中，均是以未配对蓝牙设备主动向显示设备200发送配对请求为例，对本申请实施例的方法进行说明。在一些实施例中，也可以通过用户操作未配对蓝牙设备而被动地向显示设备200发送配对请求。例如，一些手机开启蓝牙功能后，能扫描到包括显示设备200在内的很多设备。此时，如图14所示，手机的蓝牙设备列表上会显示所有扫描到的设备的名称，其中，显示设备200的名称可以是“智能电视A4”。如果想要手机与显示设备200连接，那么用户可以在蓝牙设备列表上点击“智能电视A4”，此时，手机会向显示设备200发送配对请求。显示设备200接收配对请求后，则显示配对提示页面。
为了避免已配对蓝牙设备每次与显示设备200连接时的操作过于复杂，在显示设备200中可以保存有已配对蓝牙设备的设备信息。如果显示设备200当前未与任何蓝牙设备连接，又处于可被扫描的状态，那么会优先与已配对蓝牙设备进行连接，连接时无需再次与该蓝牙设备配对。
例如，蓝牙设备A、蓝牙设备B和蓝牙设备C均可以扫描到显示设备200，但是只有蓝牙设备B是已经与显示设备200配对过的，那么如果蓝牙设备A、蓝牙设备B和蓝牙设备C均发送了相应的配对请求和连接请求，显示设备200可以优先响应于蓝牙设备B发送的连接请求而与蓝牙设备B连接。如果用户不希望再受其他蓝牙设备请求配对的干扰，可以将蓝牙可见性设置为关闭。与蓝牙设备B连接之后，如果用户想要将显示设备与蓝牙设备A连接，那么可以操作显示设备200主动进行扫描并选择扫描到的蓝牙设备A与之进行配对，并在配对后直接与蓝牙设备A连接。
当多个已配对蓝牙设备都扫描到显示设备200时，为了避免已配对蓝牙设备的连接冲突，显示设备200可以确定出最近一次连接的已配对蓝牙设备，并与该已配对蓝牙设备连接。
例如，已配对蓝牙设备a、已配对蓝牙设备b和已配对蓝牙设备c均扫描到显示设备200并向显示设备发送连接请求，显示设备200确定这三个已配对蓝牙设备中最近一次与之连接的是已配对蓝牙设备c。那么显示设备200可以优先与已配对蓝牙设备c连接。与蓝牙设备B连接之后，如果用户想要将显示设备与蓝牙设备a连接，可以在显示设备200提供的蓝牙设 备列表中选择已配对蓝牙设备a进行连接。
参见图15，图15为根据一些实施例的显示设备200的蓝牙设备列表的一种示意图。以上述扫描到显示设备200的已配对蓝牙设备a、已配对蓝牙设备b和已配对蓝牙设备c为例，显示设备200的蓝牙设备列表上可以显示已配对蓝牙设备a、已配对蓝牙设备b、和已配对蓝牙设备c的名字。如果显示设备200处于与已配对蓝牙设备c连接的状态，那么在蓝牙设备列表上的蓝牙设备c的位置处会显示“已连接”的提示，而蓝牙设备a和蓝牙设备b的位置处会显示“已配对”的提示。如果用户想要更换为将显示设备与已配对蓝牙设备a连接，那么用户可以在该蓝牙设备列表上选择蓝牙设备a，连接后，蓝牙设备a的位置处会显示“已连接”的提示，而相应的，蓝牙设备c的位置处会显示“已配对”的提示。
在一些实施例中，为了避免用户对于显示设备200蓝牙可见性开关的多次操作，显示设备200还可以将每次关机前的蓝牙可见性状态进行保存。这样，当再次开机时，显示设备200就可以恢复关机前的蓝牙可见性状态，以免用户多次重复设置和操作。
为了实现上述的显示设备200恢复关机前的蓝牙可见性状态的过程，显示设备200的控制器250还可以被配置为：保存当前的蓝牙可见性开关的状态作为保存的蓝牙可见性开关的状态；响应于显示设备200的开机，获取保存的蓝牙可见性开关的状态作为当前的蓝牙可见性开关的状态。可以在蓝牙可见性开关的状态的设置之后的任何时候保存当前的蓝牙可见性开关的状态。
本申请实施例中的显示设备200，可以根据用户的操作首先显示蓝牙设置页面。如果显示设备200当前已经与某个蓝牙设备连接，那么为了避免其他未配对的蓝牙设备对当前正常使用的显示设备200产生干扰，用户可以将蓝牙设置页面上的蓝牙可见性开关关闭，关闭后，当前已经连接的蓝牙设备不会受到影响，其他未配对的蓝牙设备则无法扫描到显示设备200，也无法向显示设备200发送配对请求，进而可以避免显示设备200显示未配对蓝牙设备的请求信息而对正常显示的内容产生干扰。
传统的显示设备与外部设备配对过程步骤繁琐、用户需要多次操作，例如启动蓝牙、用户界面手动进行蓝牙搜索、在列表中手动选择目标配对设备、手动输入蓝牙适配码；并且当遥控器等蓝牙设备在扫描设备列表中显示为硬件编码而不显示设备类型名称时，用户难以在已扫描获取的众多设备中识别目标配对设备，导致部分用户无法实现蓝牙遥控器的配对连接。
根据本申请一些实施例，还提供了能够与外部设备快速配对的显示设备及方法。
本申请实施例可以应用于各种类型的显示设备，(包括但不限于：电视、机顶盒等设备)，对应的外部设备可包括蓝牙外部设备、红外外部设备、或其它无线外部设备。下文将以电视实现与外部控制设备例如蓝牙遥控器快速配对的控制方案、及用户界面为例，对显示设备、及与外部设备快速配对的控制方法进行阐述。
图16A为根据一些实施例的显示设备与外部控制设备配对的用户界面示意图。
在一些实施例中，电视在开机状态下接收外部设备蓝牙遥控器发送的配对指令(也可称作配对请求)，所述配对指令例如可通过长按遥控器的MENU键、或长按特定键实现。
可以理解，在通常情况下用户正常按动MENU键可以在电视用户界面实现菜单显示功能，而长按时间超过预设时长阈值时，例如长按MENU键超过5秒钟，遥控器发出的指令将被电视识别为配对指令、或解配指令(也可称作解配请求)。
在一些实施例中，用户长按MENU键、或长按特定键，电视在接收到遥控器发送的指令后，将通过遥控器广播包监听判定当前电视与蓝牙遥控器的连接状态；如果确定遥控器与电视没有建立配对关系，则触发配对流程；如果确定遥控器与电视已配对，则触发解配遥控器的流程。
在一些实施例中，电视与遥控器未配对时，电视的第一控制器将基于接收的配对指令，在无需用户的其他操作情况下自动配对连接至外部设备蓝牙遥控器。
例如，在电视的任何用户界面下，用户长按蓝牙遥控器的“Menu”按键；然后可查看电视用户界面底部的提示消息；电视在收到遥控器长按“Menu”的消息后，开始连接并显示“蓝牙远程连接……”的提示消息；遥控器在与电视配对连接后，配对成功，电视用户界面的提示消 息可以改为提示用户“配对成功”的消息(未示出)；配对失败则电视用户界面的提示消息可以改为提示用户“蓝牙远程未配对”的消息(未示出)。
相较于传统外部设备与电视的配对连接，本申请提供的技术方案将所有连接动作在后台完成，只需要用户触发特定的操作，后台即可完成所有操作，在外部设备蓝牙遥控器已配对至电视后，控制电视用户界面显示配对成功信息，不再显示蓝牙启动界面，用户无需手动开启蓝牙、也无需手动控制搜索附近蓝牙设备、也不需要对搜索到的众多蓝牙设备进行选择和配对操作、更无需记录适配码与输入适配码，蓝牙遥控器配对成功后的用户界面可以显示简洁的提示信息“配对成功”。
在一些实施例中，在用户控制遥控器发出配对指令后，第一控制器可控制用户界面显示配对连接信息，例如可显示为如图16A所示的提示信息“蓝牙远程连…….”，以提示用户其发出的遥控器配对指令电视端已开始执行相应的命令，避免重复操作；在配对成功信息显示前，用户只需要一直等待即可，无需其他操作。
同理，当蓝牙遥控器与电视的配对失败时，第一控制器将控制用户界面显示表明配对失败信息，例如显示为“蓝牙远程未配对”。
在一些实施例中，在蓝牙遥控器与电视已配对，用户通过长按MENU键发送解配指令，电视在接收到蓝牙遥控器发送的解配指令后，第一控制器将基于解配指令控制电视在无需用户的其他操作情况下将已配对蓝牙遥控器进行自动解配。
在蓝牙遥控器从电视解配后，第一控制器将控制用户界面显示未配对信息，，所示提示信息例如可展示为“蓝牙远程未配对”。在蓝牙遥控器的解配过程中，用户界面依然不会有其他需要用户操作、互动的空间显示，以降低用户的操作难度、使得遥控器配对、解配操作界面更为简洁、提高配对及解配的操作便利性。
图16B示出了本申请另一些实施例显示设备与外部控制设备配对的用户界面示意图。
在一些实施例中，遥控器可配置为同时支持蓝牙以及红外功能，对于常规的换台、调节音量等功能实现，遥控器红外功能的速率、控制距离即可完成；而遥控器通过语音指令操作电视，由于其数据量的变大，则需要传输速率更高、响应更快、控制距离更远的遥控器蓝牙功能实现。
在遥控器红外功能已建立连接，蓝牙功能未建立连接时，用户通过遥控器发送了某个需要通过蓝牙传输才能实现的功能指令至电视；电视的第一控制器接收遥控器发送的功能指令，并根据功能指令控制用户界面显示用于提示用户发送配对指令方法的提示信息，以帮助用户完成遥控器蓝牙系统与电视的配对。
功能指令实施为按动语音键，可用于发送语音指令控制电视搜索节目。其中，遥控器语音键按动后发送的指令可包括触发效果、及功能应用，在遥控器蓝牙系统与电视未配对前，语音键用于使第一控制器实现其语音键触发效果，即显示关于帮助用户将遥控器蓝牙系统配对至电视的提示信息；在遥控器蓝牙系统与电视配对后，遥控器语音键按动后发送的指令则用于使电视第一控制器实现语音键对应的语音指令功能。
例如，遥控器蓝牙未连接电视情况下，用户按遥控器“Voice”语音键，电视检测到遥控器未连接而将控制用户界面显示“请先长按遥控器Menu键5秒钟以配对连接至电视”的提示消息，如图16B所示。
在一些实施例中，遥控器为红外、及蓝牙双模式，以保证遥控器在任何情况下均能使用。用户在任意用户界面下长按“Menu”按键，发送广播包给电视，触发配对、解配流程；电视在收到配对广播包后，第一控制器将判定电视与遥控器的连接状态；当遥控器的连接状态为已连接时，第一控制器将会触发蓝牙遥控器解配流程；当遥控器的连接状态为未连接时，第一控制器将触发蓝牙遥控器配对连接流程；蓝牙遥控器配对状态发生变化后，用户界面将即时给用户展示蓝牙遥控器的连接状态变化提示。
可以理解，通过以上实施例方案可实现蓝牙遥控器的极简化配对连接操作；在任何的界面下，用户仅需长按特定的按键，即可触发蓝牙遥控器的快速配对与解配，电视会根据当前的蓝牙外设的连接状态进行具体的配对、解配等流程的自启动，同时将配对、解配结果实时 展现给用户。该方法不仅便捷、简单、高效，同时能够增强产品的智能化，提高产品的交互体验，从而提升产品竞争力。
图16C示出了本申请另一些实施例显示设备与外部控制设备配对的用户界面示意图。
在一些实施例中，本申请提供的显示设备还提供了与外部设备快速配对的导航功能，第一控制器控制用户界面显示用于外部设备配对至显示设备的导航界面，如图16C所示；通过简洁的用户界面，提示用户可通过长按遥控器MENU键实现遥控器配对，并且导航界面还包括可变换显示的控件，如显示为跳过，则代表用户点击“跳过”按钮后，电视将跳过蓝牙遥控器配对流程。
例如，在电视首次使用、或整机重置后，用户界面将显示如图16C所示的导航界面；在图示的导航界面中，可以显示提示信息，以提示用户配对蓝牙遥控器及具体的配对方法；用户可点击“跳过”以忽略蓝牙遥控器的配对；用户在按照提示配对蓝牙遥控器成功后，第一控制器通过页面监听遥控器连接状态变化为已连接后，用户界面中的“跳过”按钮将自动变换为“继续”按钮，并将提示信息改为显示表示蓝牙遥控器配对成功的信息。
可以理解，在外部设备配对成功前，用户界面中的控件显示为用于放弃配对操作的第一按钮；在外部设备配对成功后，控件显示为用于跳转至其它功能配置界面的第二按钮，例如显示为“继续”按钮，如图16D所示。
通过该方法，用户能够快速、便捷地实现蓝牙遥控器的配对与解配，给用户直观的状态提示，不需要繁琐的连接操作；同时，在使用遥控器上蓝牙按键的时候，会给用户具体的操作方法，方便用户快速使用蓝牙遥控器，提升用户的体验。
本申请提供了一种与外部设备快速配对的显示设备及控制方法。显示设备包括显示器以及与显示器连接的控制器，控制器被配置成：接收外部设备发送的操作请求；响应于所述操作请求，使显示设备在无需用户的其他操作情况下自动进行相应的操作，其中，所述操作请求包括配对请求和解配请求，所述显示设备响应于所述配对请求而与所述外部设备自动配对连接，以及所述显示设备响应于所述解配请求而与所述外部设备自动解配。

在一些实施例中，所述控制器还被配置为：响应于开机启动，控制显示器的用户界面显示用于将外部设备配对至显示设备的导航界面，所述导航界面包括可变换显示的控件；其中，在所述外部设备配对成功前，所述控件显示为用于选择放弃配对操作的第一按钮；在所述外部设备配对成功后，所述控件显示为用于选择跳转至其它功能配置界面的第二按钮。
在一些实施例中，所述方法包括：接收外部设备发送的操作请求；响应于所述操作请求，使显示设备在无需用户的其他操作情况下自动进行相应的操作，其中，所述操作请求包括配对请求和解配请求，所述显示设备响应于所述配对请求而与所述外部设备自动配对连接，以及所述显示设备响应于所述解配请求而与所述外部设备自动解配。
在一些实施例中，所述方法还包括：响应于所述操作请求的接收，确定所述显示设备是否与所述外部设备配对连接；响应于确定所述显示设备与所述外部设备未配对连接而将所述操作请求用作所述配对请求，以与所述外部设备自动配对连接；以及响应于确定所述显示设备与外部设备已配对连接而将所述操作请求用作所述解配请求，以与所述外部设备自动解配。
在一些实施例中，所述方法还包括：接收外部设备发送的功能指令；确定所述显示设备 是否与所述外部设备配对连接；响应于确定所述显示设备与所述外部设备配对连接，基于所述功能指令的接收而触发显示器的用户界面显示用于提示用户发送配对请求的方法的提示信息；响应于确定所述显示设备与外部设备已配对连接，基于所述功能指令而控制所述显示设备实现对应的功能。
