Description

显示控制方法和显示装置
本申请要求于2018年12月24日提交中国专利局，申请号为CN201811579696.2，申请名称为“一种显示控制方法和显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示控制方法和显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
显示面板具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。其中，显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。随着显示面板不断发展，显示画面也越来越鲜艳分明，长时间观看会造成视觉疲劳。
现今的儿童由于对动画片的喜爱，花在观看电视上的时间越来越久，而儿童的自制力较差，并不懂得克制，这样长时间的观看会对视力造成比较大的影响，造成现在儿童近视的比例也越来越高。除了靠家长的人为约束之外，现在也有一些可以设定定时关闭的电视，但往往比较死板，如果成人在观看电视，那么电视自动关闭以后就只能将电视重新启动。儿童因为长时间观看会导致视力大下降，同时定时关闭也会对成人观看带来不少的麻烦。
发明内容
本申请提供一种显示控制方法和显示装置，智能保护儿童视力的同时不影响成人观看。
为实现上述目的，本申请提供了一种显示控制方法，包括：
侦测节目信息：获取当前播放的节目信息；
判断儿童节目：基于所述节目信息识别儿童节目；以及
控制播放：如果不是儿童节目，所述电视机正常播放；如果是儿童节目，启动预设的保护机制。
本申请还公开了一种显示控制方法，包括：
侦测节目信息：获取当前播放的节目信息；
判断频道：基于频道信息识别是否为少儿频道，如果不是，电视机正常播放；如果是， 执行判断色彩饱和度步骤；
判断色彩饱和度：判断所述色彩饱和度是否大于80，如果不是，电视机正常播放；如果是，执行判断播放时长步骤；
判断播放时长：判断所述播放时长是否大于所述预设时间，如果不是，电视机正常播放；如果是，执行启动保护机制步骤；以及
启动保护机制：弹出提示信息和密码输入框，如果输入密码，电视机正常播放；如果不是，关闭电视机。
本申请还公开了一种显示装置，所述装置包括：电视机；
侦测部件：被设置为获取当前播放的节目信息；
判断部件，被设置为判断所述节目信息是否为儿童节目；以及
控制部件：被设置为控制所述电视机是否关闭，如果不是儿童节目，所述电视机正常播放；如果是儿童节目，启动保护机制。
相对于在电视机增加童锁的方案来说，本申请首先获取当前播放内容的节目信息，并根据节目信息判别当前播放内容是否为儿童节目。智能识别是否为儿童节目，如果是儿童节目就启动相应的保护机制，可以有效地限制儿童观看电视，从而对儿童的视力进行保护，同时不影响成人的观看体验。
附图说明
所包括的附图用来提供对本申请实施例的进一步的理解，其构成了说明书的一部分，用于例示本申请的实施方式，并与文字描述一起来阐释本申请的原理。显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。在附图中：
图1是本申请实施例一种显示控制方法的流程的示意图；
图2是本申请实施例另一种显示控制方法的流程示意图；
图3是本申请实施例一种智能保护儿童视力的装置示意图。
具体实施方式
需要理解的是，这里所使用的术语、公开的具体结构和功能细节，仅仅是为了描述具体实施例，是代表性的，但是本申请可以通过许多替换形式来具体实现，不应被解释成仅受限于这里所阐述的实施例。
在本申请的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示相对重要性，或者隐含指明所指示的技术特征的数量。由此，除非另有说明，限定有“第一”、“第 二”的特征可以明示或者隐含地包括一个或者更多个该特征；“多个”的含义是两个或两个以上。术语“包括”及其任何变形，意为不排他的包含，可能存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和/或其组合。
另外，“中心”、“横向”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系的术语，是基于附图所示的方位或相对位置关系描述的，仅是为了便于描述本申请的简化描述，而不是指示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，或是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
如图1所示，本申请实施例公开了一种显示控制方法，包括：
S11、侦测节目信息：获取当前播放的节目信息；
S12、判断儿童节目：基于所述节目信息识别儿童节目；
S13、控制播放：如果不是儿童节目，所述电视机正常播放；如果是儿童节目，启动预设的保护机制。
本申请首先获取当前播放内容的节目信息，并根据节目信息判别当前播放内容是否为儿童节目。智能识别是否为儿童节目，如果是儿童节目就启动相应的保护机制，可以有效地限制儿童观看电视，从而对儿童的视力进行保护，同时不影响成人的观看体验。
在一实施例中，节目信息包括频道信息；判断儿童节目包括：
基于频道信息识别儿童节目。
不同的频道会有不同的频道信息，根据不同的频道信息进行识别是否为少儿频道，如果是少儿频道就有很大的机率是播放儿童节目，这样优先进行筛选，可以快速进行排除。如果不是儿童频道，不影响继续观看。
进一步的，基于频道信息识别儿童节目的步骤包括：
预设儿童节目的频道信息；
将预设频道信息与当前节目频道信息进行比较；以及
如果预设频道信息与当前节目频道信息一致，识别为儿童节目。
可以预先设置儿童节目的频道信息，如央视的儿童频道、各地方卫视的儿童频道，将这些频道的信息预先设置存储。当检测到当前频道和预设频道信息一致时，此时就是识别为儿童节目，相应的采取进一步的保护措施。
频道信息包括频道频率信息，在进行预设频道和当前频道对比时，优先对比频道的频率 信息。将预设频道的频道频率与当前节目频道的频道频率进行比较；如果频道频率相同，判断预设频道信息与当前节目频道信息一致，如果频道频率不同，判断预设频道信息与当前节目频道信息不一致。由于不同频道使用的频率带宽是不同的，比如中央电视台1套节目频率为207～215MHz，而少儿频道的频率是231～239MHz。根据频道信息判断是否为少儿频道，直接可以判断是否在观看少儿频道和其他频道。少儿频道播放儿童节目较多，可以基于频道信息尽行判断，更加快捷。
节目信息还包括色彩饱和度的信息，所述基于所述节目信息识别儿童节目的步骤包括：基于频道信息和色彩饱和度信息识别儿童节目。不同节目的色彩饱和度有很大的差异，儿童节目如动画片比较鲜艳，色彩饱和度比较高，可以对当前节目进行色彩饱和度识别，当色彩饱和度满足一定条件时，识别为儿童节目，判断更加精准。
进一步的，可以两者结合进行判断。节目信息包括频道信息和色彩饱和度信息；基于节目信息识别儿童节目的步骤包括：
基于频道信息和色彩饱和度信息识别儿童节目。
根据频道信息判断是否为少儿频道，直接可以判断是否在观看少儿频道或其他频道。儿童节目色彩饱和度较高，根据色彩饱和度判断也可进行儿童节目识别。两者结合，判断当前播放内容的准确度提高。
具体的基于频道信息和色彩饱和度信息识别儿童节目的步骤包括：
判断频道信息是否为少儿频道，如果是，读取色彩饱和度信息，当色彩饱和度信息是否超过预设值，识别为儿童节目。
当根据频道信息判断为少儿频道后，读取色彩饱和度信息，如果到超过预设值后，判断为儿童节目。由少儿频道再进行色彩饱和度判断，这样判断准确度提高，不易发生误判。对于色彩饱和度与设置的设定，可以先利用计算机大数据算法统计足够数量的儿童节目，统计对比分析得出一个色彩饱和度的区间范围值。当满足这个范围值的电视节目有很大的概率为儿童节目。设定色彩饱和度预设值范围为70至100。设定黑色画面饱和度为0，而全亮度的彩色(含红、绿、蓝、黄等等)饱和度为100，儿童节目色彩饱和度较高，当色彩饱和度达到70时，有较大几率为儿童节目。具体的，将色彩饱和度预设值为80，当色彩饱和度信息超过80时，识别为儿童节目。
在一实施例中，保护机制包括：关闭电视机。
保护儿童视力，主要就是减少儿童观看电视节目的时长，保护机制最直接的方法就是关闭电视机，这样可以最大化的保护儿童视力。
也可以在已经识别为儿童节目后，弹出提示信息，根据信息进行判断是否为成人观看，如果是成人观看可以继续正常播放，如果没有返回判断信息或长时间未反应，可以判断为儿 童观看，此时关闭电视机。因为年龄较小的儿童并不具备识别提示信息的能力，也无法做到反馈提示信息。这样的话，就不会影响成人的观看，根据不同人群进行判断，使判断机制更加合理。
当然，也可以对当前频道进行切换。具体的步骤为：
自动切换儿童节目，将当前频道进行切换至非儿童节目的频道。
当检测为儿童节目后，可以自动切换频道，切换至非儿童节目的频道，比如教育频道、科教频道等。儿童在看到切换频道后，注意力下降，对于继续观看的兴趣大大减少，从而减少儿童的观看时长，也有利于培养儿童对于科学探索的兴趣。
在一实施例中，所述启动预设保护机制的步骤包括：
设定预设时间并记录播放时长，如果所述播放时长大于预设时间，当前画面自动切换至预设蓝屏画面。
设定预设的时间相对可以保护儿童的视力，做到合理分配。只有播放时间超过预设时间时，将画面切换预设的蓝屏画面，只有声音并无画面，提示儿童播放时间超时，避免了长时间观看带来的不好影响。具体的，可以设置预设时间为0.5小时，一般比如动画片的单集时长不会超过0.5小时，可以满足儿童的观看需求。同时0.5小时也不会带来视觉疲劳的观感。当然可以针对不同年龄阶段的儿童设置不同的预设时长，做到合理有效的规划。
在一实施例中，保护机制包括：设定预设时间并记录播放时长，如果播放时长大于预设时间，弹出提示信息和密码输入框，输入密码进行观看，否则关闭电视机。
保护机制包括的这些操作，既是对儿童观看电视进行保护，同时不限制成人的观看体验。成人有可能也会观看儿童节目，成人输入密码后可以继续观看，不对成人观看进行限制。
如图2所示，本申请实施例公开了一种显示控制方法，包括：
S21、侦测节目信息：获取当前播放的节目信息；
S22、判断频道：基于频道信息识别是否为少儿频道，如果不是，步骤S26；如果是，执行判断色彩饱和度步骤；
S23、判断色彩饱和度：判断所述色彩饱和度是否大于80，如果不是，步骤S26；如果是，执行判断播放时长步骤；
S24、判断播放时长：判断所述播放时长是否大于所述预设时间，如果不是，步骤S26；如果是，执行启动保护机制步骤；
S25、启动保护机制：弹出提示信息和密码输入框，如果输入密码，步骤S26；如果不是，执行步骤26；
S26、关闭电视机；
S27、电视机正常播放。
本申请的提示信息包括温馨提示和解锁提示。本申请首先获取当前播放内容的节目信息，并根据节目信息判别当前播放内容，由于不同频道使用的频率带宽是不同的，比如中央电视台1套节目频率为207～215MHz，而少儿频道的频率是231～239MHz。根据频道信息判断是否为少儿频道，直接可以判断是否在观看少儿频道和其他频道。当根据频道信息判断为少儿频道后，读取色彩饱和度信息，如果到超过预设值后，判断为儿童节目。由少儿频道再进行色彩饱和度判断，这样判断准确度提高，不易发生误判。保护儿童视力，主要就是减少儿童观看电视节目的时长，如果播放时长超过预设时间，对电视弹出提示信息和密码输入框。这样既是对儿童观看电视进行保护，同时不限制成人的观看体验。成人有可能也会观看儿童节目，成人输入密码后可以继续观看，不对成人观看进行限制。
如图3所示，本申请实施例公开了一种显示装置，包括：电视机10；
侦测部件40：被设置为获取当前播放的节目信息；
判断部件30，被设置为判断节目信息是否为儿童节目；
控制部件20：被设置为控制电视机是否关闭，如果不是儿童节目，电视机正常播放；如果是儿童节目，启动保护机制。
装置主要功能在于这三个部件，根据这三个部件可以对播放内容进行分析判断，并作出相应的控制。在显示装置中，通常由外接网络作为侦测部件，进行当前节目信息的获取。机顶盒作为判断部件进行节目信息判断，最后通过主机板作为控制部件，控制电视机是否关闭，并采取相对应步骤进行操作。本装置最大化的对儿童观看儿童进行限制，从而保护儿童视力，同时不影响成人观看体验。
需要说明的是，本方案中涉及到的各步骤的限定，在不影响具体方案实施的前提下，并不认定为对步骤先后顺序做出限定，写在前面的步骤可以是在先执行的，也可以是在后执行的，甚至也可以是同时执行的，只要能实施本方案，都应当视为属于本申请的保护范围。
本申请的技术方案可以广泛用于使用各种显示面板的显示装置，如扭曲向列型(Twisted Nematic，TN)显示面板、平面转换型(In-Plane Switching，IPS)显示面板、垂直配向型(Vertical Alignment，VA)显示面板、多象限垂直配向型(Multi-Domain Vertical Alignment，MVA)显示面板，当然，也可以是其他类型的显示面板，如有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板，均可适用上述方案。
以上内容是结合具体的可选的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
