Description

一种分体式电视及其主机单元 技术领域
本申请涉及液晶电视技术领域，尤其涉及一种分体式电视及其主机单元。
背景技术
目前电视一般采用一体化方案，即电视机内部集成电视主板电路和音响单元等，因为电视面板足够大，因此可以在电视面板背面进行天线布放。
目前电视终端的发展趋势是大屏化、轻薄化，一种解决思路是将电视机的音响单元及主板电路独立出来，独立成特殊的主机单元(soundbar单元)，其他部分保留在显示单元，从而形成分体式电视，这样做可以让显示单元做得很薄，分体式电视主要包括：带电视主板的主机单元(soundbar单元)和电视显示屏。
然而智能电视内部的主板电路上可能存在多个天线，常规一体化电视背板尺寸比较大时，有足够的空间实现多个天线排放；而对于分体式电视，集成电视主板的soundbar单元尺寸较小，多个天线距离太近，容易相互干扰，导致无法正常工作。
可见一体化电视机存在其固有缺点，即电视受限于内部音响单元和主板电路等，厚度无法做得很薄；而分体式电视机因为主机单元内部同时存在多个天线，是个技术难点。如果天线设计不合理的话，天线之间容易相互干扰，从而导致系统功能无法正常实现。
发明内容
为了解决当前分体式电视内部天线之间容易相互干扰的技术问题，本申请提供了一种分体式电视及其主机单元。
根据本申请实施例的第一方面，提供一种一种分体式电视，包括通过线缆连接的主机单元和显示单元，所述主机单元包括主板区域和音响区域，所述主 板区域上排布有N根天线，N为大于1的整数，其中，
至少有两根天线在主板区域垂直排布形成一个天线组，在有多个天线组时，天线组之间在主板区域分开排布。
可选地，天线的根数N为偶数时，每两根天线垂直在主板区域排布形成一个天线组，天线的根数N为奇数时，N-1根天线中，每两根天线在主板区域垂直排布形成一个天线组。
可选地，所述主板区域包括主电路板、按键板和电源板，其中主电路板和电源板分别连接在按键板的两端；
在有多个天线组时，其中至少一个天线组排布在主电路板上，且其余天线组排布在电源板上。
可选地，所述主板区域上布置4根天线，分别为第一WIFI天线、第二WIFI天线、蓝牙天线和遥控器天线。

根据本申请实施例的第二方面，提供一种分体式电视的主机单元，包括主板区域和音响区域，所述主板区域上排布有N根天线，N为大于1的整数，其中，
至少有两根天线在主板区域垂直排布形成一个天线组，在有多个天线组时， 天线组之间在主板区域分开排布。
本申请实施例提供的分体式电视及其主机单元，具有以下有益效果：

依据本申请的一示例性实施例，提供一种分体式电视，如图1所示，包括通过线缆连接的主机单元(soundbar单元)10和显示单元20，其中，主机单元10包括主板区域和音响区域，主板区域上排布有N根天线，N为大于1的整数，由于将电视的音响区域及主板区域独立出来，独立成特殊的主机单元(soundbar单元)，其他部分保留在显示单元，从而形成分体式电视，这样做可以让显示单元做得很薄。
电视的音响区域主要是实现电视音频信号的外放，电视的主板区域用于实现电视图像信号和音频信号的处理，以及实现电视的遥控和无线通信等功能，因此，电视的主板区域上布置有多根天线，本实施例中，至少有两根天线在主板区域垂直排布形成一个天线组，在有多个天线组时，天线组之间在主板区域分开排布。
可选地，如图2所示，音响区域包括布置第一喇叭的第一音响子区域101和布置第二喇叭的第二音响子区域102，第一音响子区域101和第二音响子区域102布置在主板区域103的两侧。
为了避免天线之间相互干扰，天线之间需要满足一定的隔离度要求，本实施例中，对于多根天线，至少有两根天线是垂直排布的，因而这两根天线在空 间上是正交的，通过空间正交可以避免这两根天线的相互干扰，而两根天线垂直排布，不需要占用太大空间，和其他天线或天线组之间通过距离进一步实现隔离，从而可以满足多根天线的隔离度要求，避免分体式电视内多根天线间的相互干扰。
可选地，天线的根数N为偶数时，每两根天线垂直在主板区域排布形成一个天线组，在有多个天线组时，天线组之间在主板区域分开排布。本实施例中，对于有偶数根天线的情况，尽可能地利用天线组的优点，减少天线排布占用的空间，并尽可能远地拉开天线组之间的距离，从而可以将多根天线之间的干扰降到最低。
可选地，天线的根数N为奇数时，N-1根天线中，每两根天线在主板区域垂直排布形成一个天线组，在有多个天线组时，天线组之间在主板区域分开排布，另外，天线组与剩余的未在天线组中的1根天线分开布置，本实施例中，对于有奇数根天线的情况，尽可能地利用天线组的优点，减少天线排布占用的空间，并尽可能远地拉开天线组之间的距离，从而可以将多根天线之间的干扰降到最低。
可选地，主板区域103包括主电路板103a、按键板103b和电源板103c，其中主电路板103a和电源板103c分别连接在按键板103b的两端。
在有多个天线组时，其中至少一个天线组排布在主电路板103a上，且其余天线组排布在电源板103c上。
主电路板分布有电视主要电路；按键板103b是用户和设备的接口，和传统电视按键板实现的功能类似，用户通过按键输入，实现电视频道、音量等的更改，同时按键板集成红外接收电路，实现对遥控器信号的接收，按键板功能比较成熟，可以参考传统电视按键板的制作方式；电源板103a上具有用于为主机单元供电的电源模块。
本实施例中，将天线组分开布置在按键板103b两侧的主电路板103a和电源板103c，按键板103b对于天线类似一个分割面，从而提高左右侧天线之间的隔离度。
具体布置时，对于仅有一个天线组和1根天线的情况，可以将一个天线组排布在主电路板，将其余的1根天线排布在电源板上，当然，也可以将一个天 线组排布在电源板上，将其余的1根天线排布在主电路板上。
电视天线一般包括WIFI天线(支持多输入输出MIMO功能则需要两根WIFI天线)、蓝牙天线和遥控器天线。这4根天线在电视背板尽量远离，以实现彼此之间互不干扰并行工作。
考虑到产品外观简洁，电视天线全部采用内置方式。
可选地，本实施例中主板区域103上布置4根天线，分别为第一WIFI天线、第二WIFI天线、蓝牙天线和遥控器天线。
第一WIFI天线的天线频率为2.4GHZ，第二WIF天线的天线频率为5GHZ，或者，第一WIFI天线的天线频率为5GHZ，第二WIF天线的天线频率为2.4GHZ，蓝牙天线的天线频率为2.4GHZ，智能遥控器天线的天线频率为2.4GHZ，当然还可以是其他频率的天线。
下面以主板区域上排布这四根天线为例，给出本发明分体式电视的优选实施例。
如图1所示，分体式电视包括通过线缆连接的主机单元(soundbar单元)10和显示单元20。
其中，显示单元20为电视机的屏幕，和电脑液晶显示屏类似，因为内部功能单一，可以实现电视屏幕较薄。
主机单元10，是集成电视主板模块的soundbar，包括主板区域和音响区域，如图2所示，和传统的soundbar类似，Soundbar单元的两侧为喇叭，即音响区域包括布置第一喇叭的第一音响子区域101和布置第二喇叭的第二音响子区域102，所述第一音响子区域101和第二音响子区域102布置在主板区域103的两侧。
如图3所示，主板区域103包括主电路板103a、按键板103b和电源板103c，其中主电路板103a和电源板103c分别连接在按键板103b的两端。
电源板103c上布置有电源模块，该电源模块实现市电(90V～240V)转换，为主机单元提供直流供电。
主电路板103a上布置有电视主芯片、连接第一WIFI天线和第二WIFI天线的WIFI模块、连接蓝牙天线的蓝牙模块、实现音频处理的音频电路。
电视主芯片主要包括中央处理单元CPU+内存DDR+EMMC(Embedded Multi Media Card)。本实施例中主电路板和现有一体化电视内部主电路板功能相同，只是根据soundbar结构需要，将主电路板形状制作成长方形。
按键板103c是用户和设备的接口，和传统电视按键板实现的功能类似。用户通过按键输入，实现电视频道、音量等的更改，同时按键板集成红外接收电路，实现对遥控器信号的接收。按键板功能比较成熟，可以参考传统电视按键板的制作方式。
对于主板区域的4根天线，由于主机单元本身比较小，两边又被喇叭占用，为了避免喇叭外部金属网对天线的屏蔽，4天线只能布放在主板区域。同时在狭小的主板区域布放4根可能工作在同频(2.4G)的天线，是分体式电视设计的一大挑战。
为了实现分体式电视的性能，需要考虑到以下因素：
1)WIFI性能对分体式电视十分重要，因此要优先满足WIFI性能要求；
2)WIFI天线之间需要满足一定的隔离度要求(大于15dB)，这样才能保证不被互相干扰；
3)WIFI天线和蓝牙天线/遥控器天线之间要满足较大的隔离度要求(大于30dB)，这样才能保证WIFI天线和蓝牙天线/遥控器天线之间不会互相干扰；
4)蓝牙天线和遥控器天线需要满足一定的隔离度要求(大于20dB)，这样才会保证蓝牙天线和遥控器天线之间不会互相干扰。
可见不同的天线之间对隔离度的要求是不同的，为了满足各天线之间不被互相干扰而能够正常工作，本实施例中，如图3所示，第一WIFI天线A1横向排布，第二WIFI天线A2竖向排布，第一WIFI天线A1和第二WIFI天线A2的排布是垂直排布，以通过空间正交来实现两者的隔离度要求。如图3所示，遥控器天线B1是横向排布的，蓝牙天线B2是竖向排布的，遥控器天线B1和蓝牙B2也通过彼此垂直排布，同样通过空间正交实现两者的隔离度。
当然，第一WIFI天线A1和第二WIFI天线A2之间的位置可以对调，即第一WIFI天线A1竖向排布，第二WIFI天线A2横向排布，不会影响性能；蓝牙天线和遥控器天线也可以交换位置，即遥控器天线B1是竖向排布的，蓝牙天线 B2是横向排布的，不影响性能。
本实施例中第一WIFI天线和第二WIF天线排布形成的天线组，与蓝牙天线和遥控器天线排布形成的天线组通过距离来提高隔离度，两个天线组分别布置在主电路板103a远离按键板103b的一端和电源板103c远离按键板103b的一端，中间通过按键板103b分隔开两者，按键板103b对于天线类似一个分割面，从而提高左右侧天线组之间的隔离度。
本实施例中，主板区域和音响区域置于同一外壳中，外壳采用塑料或金属，是主机单元的容器，类似传统的soundbar外壳方案。
当4根天线采用上述布置时对天线的隔离度进行测试，如图4为测试的第一WIFI天线和第二WIFI天线之间的隔离度示意图，图5为本发明实施例测试的蓝牙天线和遥控器天线之间的隔离度示意图，图6为本发明实施例测试的两个天线组之间的隔离度示意图，图4、图5和图6中横坐标表示工作频率，纵坐标表示测得的隔离度，可见，各天线之间可以满足隔离度要求，可以满足分体式电视的性能要求。
本发明实施例通过电视分体式设计，可以大大降低电视显示屏的厚度，使得产品更满足用户对时尚和美学的追求；同时内部多天线之间合理的排布设计，很好地实现了多根天线在电视主机内共存工作的技术难点。
依照本发明另一实施例，提供一种分体式电视的主机单元，包括主板区域和音响区域，所述主板区域上排布有N根天线，N为大于1的整数，其中，
至少有两根天线在主板区域垂直排布形成一个天线组，在有多个天线组时，天线组之间在主板区域分开排布。

可选地，所述主板区域包括主电路板、按键板和电源板，其中按键板位于主电路板和电源板之间；
在有多个天线组时，其中至少一个天线组排布在主电路板上，且其中至少一个天线组排布在电源板上。
可选地，所述主板区域上布置4根天线，分别为第一WIFI天线、第二WIFI天线、蓝牙天线和遥控器天线。
