背景技术
显示技术发展越来越先进，越来越具有科技感。其趋势从非自发光到自发光，即LCD液晶技术到OLED技术；厚度不断减少，变得越来越薄，使手机等设备越来越薄；实现柔软度，从原来的硬性屏到柔性屏，甚至实现折叠屏幕、可卷曲屏幕；实现透明效果，实现透明电视。
但透明电视在实际应用中，由于背部光线比较亮会让观众看见电视背后的影像，严重影响视觉效果；由于使用了透明技术，当要显示黑色的时候，只能利用人眼的视觉漏洞，只能使用其他颜色衬托，成像黑色的视觉效果，但如果黑色面比较大的时候，则黑色效果会大打折扣；另外，当显示屏应用在笔记本电脑的时候，虽可以实现高科技感觉，但由于用户笔记本电脑要处理个人的事情，则透明的显示屏可能会泄露信息。

具体实施方式
下面结合附图和实施例对本发明实施例作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明实施例，而非对本发明实施例的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明实施例相关的部分而非全部结构。
本方案中提及的显示屏可应用于透明显示屏、透明柔性屏、显示器、电视、笔记本电脑、手机、平板电脑、手持设备、广告机、面板机、终端设备、支付设备、智能挡风玻璃(包括汽车、轮船、高铁、飞机等)、智能头盔、智能手表、智能相册、智能黑板、智能屏风等设备。显示屏的控制方法可以有集成应用设备的主控设备实现，或者通过设置的单独的控制设备实现。
图1为本发明实施例提供的一种显示屏控制方法的流程图，本实施例可适用于对显示屏的成像进行控制，该方法可以由显示屏集成的或者和显示屏关联的计算处理装置执行，如图1所示，具体包括如下步骤：
步骤S101、确定显示屏当前透明度和显示模式，所述显示模式包括外部设置模式和自动同步模式。
本方案中，显示屏包括LCD液晶板和自发光显示屏，其中自发光显示屏如OLED显示屏。其中，LCD液晶板的像素单元与自发光显示屏的像素单元一一对应。透明度可以用0.0-1.0的数值进行表示，其表征了显示屏的透明程度。可以定义为0.0为透明度最低，1.0为透明度最高。显示模式指当前显示屏进行显示控制时的模式，其包括外部设置模式和自动同步模式。其中，外部设置模式接收外部的显示图形信息以进行后续显示控制，而自动同步模式接收自发光显示屏当前显示信息，以进行后续显示控制。其中，该显示模式的确定可以是根据检测到的设置指令进行确定。如设置为外部设置模式还是自动同步模式。
步骤S102、根据所述当前透明度和所述显示模式，确定所述LCD液晶板各像素对应的透明度值。
其中，不同的透明度和显示模式对应不同的需要控制呈现的信息，即不同的LCD液晶板像素的透明度值。其 中，显示模式下显示图像的灰度值可以用0-255来表示，可以定义为0为灰度最黑，255为灰度最白。
步骤S103、根据所述各像素对应的透明度值控制所述LCD液晶板进行光线处理。
其中，在确定出各个像素对应的透明度值后，根据该透明度值控制LCD液晶板进行光线处理。具体的，可以是根据各像素对应的透明度值确定LCD液晶板各个晶元的控制电压或控制电流，通过对各个晶圆的控制电压和控制电流的施加以实现对光线的通过率进行控制，进而实现不同透明度的呈现。如确定出的透明度值0则光线通过率对应为0，如透明度值1.0则光线通过率为100％。
具体的，LCD液晶板控制原理如下：
如图2所示，图2为一种示例性的液晶板原理示意图。LCD液晶板以TN型液晶为例，TN型液晶是顺着长轴方向串接，长轴间彼此平行方式排列。当接触到槽装表面时，液晶分子就会顺着槽的方向排列于槽中。当液晶被包含在两个槽状表面中间，且槽的方向互相垂直，则液晶分子的排列为：上表面分子：沿着a方向；下表面分子：沿着b方向；介于上下表面中间的分子：产生旋转的效应。因此液晶分子在两槽状表面间产生90度的旋转。其偏转效果图如图3所示，图3为一种示例性的液晶分子翻转效果图。其中，液晶在电压做用下均匀分布，即当在上下表面之间加电压时，液晶分子会顺着电场方向排列，形成直立排列的现象。此时入射光线不受液晶分子影响，直线射出下表面。
图4为一种示例性的液晶偏光特性示意图。LCD液晶板存在偏光板的特性，如图4(上)所示，将非偏极光(一般光线)过滤成偏极光，当非偏极光通过a方向的偏光片时，光线被过滤成与a方向平行的线性偏极光，线性偏极光继续前进，通过第二片偏光片时，光线通过；如图4(下)所示，线性偏极光继续前进，通过第二片时，光线被完全阻挡。在具体的对光线通过性的控制过程中，当上下偏光片相互垂直时，若未施加电压，光线可通过，当施加电压时，光线会被相应遮挡。在对LCD液晶板施加电压后，电流通过电晶体产生电场变化，造成液晶分子偏转，由此以改变光线的偏极性，再通过设置的偏光片对通过的光线进行遮挡/通过，以实现不同的明暗状态。
在一个实施例中，可以记录不同的电压或电流与光线通过率的对照表，根据该对照表查询当前光线通过率对应的电压或电流，并对LCD液晶板施加对应的电压或电流以实施对应的光线通过率控制。
图4a为另一种示例性的液晶屏原理示意图。图4b为另一种示例性的液晶屏原理示意图。其与图2所示的最大区别在于不需要偏振光片，以及液晶容器内壁没有设有槽状表面。当没有通电时，如图4a所示，由于没有内壁槽状表面的牵引，其内部所含有的液晶分子呈现无序排列状态，光线无法透过玻璃膜，这时看到的状态就是白色非透明状态。当通电的条件下，如图4b所示，其内部液晶分子有序排列，光线可以顺利透过玻璃膜，这时看到的状态就是透明状态。
在一个实施例中，可以记录不同的电压或电流与光线通过率的对照表，根据该对照表查询当前光线通过率对应的电压或电流，并对液晶板施加对应的电压或电流以实施对应的光线通过率控制。
由上述方案可知，本方案中，通过确定显示屏当前透明度和显示模式，所述显示模式包括外部设置模式和自动同步模式；根据所述当前透明度和所述显示模式，确定所述LCD液晶板各像素对应的透明度值；根据所述各像素对应的透明度值控制所述LCD液晶板进行光线处理。本方案解决了现有技术中透明显示屏显示效果不理想，以及隐私泄露的问题，提升了显示效果以及隐私防护能力。
图5为本发明实施例提供的另一种显示屏控制方法的流程图，给出了一种外部显示模式下的显示屏控制方法。如图5所示，具体包括：
步骤S201、确定显示屏当前透明度和显示模式，所述显示模式包括外部设置模式和自动同步模式。
步骤S202、当确定出所述显示模式为外部显示模式时，接收显示图形信息，根据所述当前透明度和所述显示图形信息确定LCD液晶板各像素对应的透明度值。
在一个实施例中，以双面透明广告电视为例进行说明，由于想广告牌两边的人都可以观看广告，则显示器实现透明效果。当对其设置为外部显示模式时，显示屏接收用户发送的显示图形信息。示例性地，当显示图形信息为空的时候，默认为一张灰度为全白的图形，则灰度值为255。假设当前用户设定的透明度为1.0，结合当前透明度设置，计算公式可以是(255/255)*1.0＝1.0，则控制LCD液晶板的整体透明度为1.0，此时显示屏背后看到的显示屏前面看到的图像互为镜像图像，实现前后同时观看的效果。假设当前用户设定的透明度为0.2，结合当前透明度设置，则(255/255)*0.2＝0.2，则控制LCD液晶板的整体透明度为0.2，此时背后看见的就是很深的灰色，没法看清细节，但可以看见大图形的轮廓。示例性地，当前用户设定的透明度为0.0，结合当前透明度设置，则(255/255)*0.0＝0.0，则控制LCD液晶板的整体透明度为0.0，此时，背后看见的就是一片漆黑，在实现透明显示器，实现科技感的同时，实现个人隐私的保护。
在一个实施例中，以笔记本电脑显示屏为例子进行说明，由于用户要使用笔记本电脑处理个人事务的时候，当 想遮挡一部分内容的时候。示例性地，为了便于理解，如图5a所示，图5a为分辨率10*10的图形信息的第一示意图，从图5a中可以看出每个像素的颜色深浅不一，并且构成“A”字形状。假设当前用户设定的透明度为0.5，结合当前透明度设置，则把每个像素的灰度值转化为透明度再乘以当前透明度设置则为(x/255)*0.5，从而确定每个像素对应的透明度。示例性地，该图形可以通过用户打开的视窗窗口作为不透明区域，根据用户打开地窗口生成对应地图形信息。在实现透明显示器，实现科技感的同时，该模式可以指定特定图形进行复杂的透明度处理，实现各种情况的需要。
在一个实例中，以笔记本电脑显示屏为例子进行说明，由于屏幕两边都是透明地，电脑供应商再屏幕上没有地方印刷自己商标，当电脑进入休眠状态，则可以指定显示指定的图案，包括商标。示例性地，为了便于理解，如图5b所示，图5b为分辨率10*10的图形信息的第二示意图，从图5b中可以看出每个像素的颜色深浅不一，构成“A”字形状，并且周边黑只有文字部分较浅色。假设当前设定的透明度为0.8，结合当前透明度设置，则把每个像素的灰度值转化为透明度再成语当前透明度设置则为(x/255)*0.5，从而确定每个像素对应的透明度，于是从屏幕的后面可以看见一个白色的“A”字。进一步设计，可以在“A”对应的位置控制OLED显示一个彩色的“A”字，则可以看见在一个整个版面都是黑色的背景上出现一个颜色鲜艳且发亮的“A”字。在实现透明显示器，实现科技感的同时，该模式可以指定特定图形进行复杂的透明度处理，实现各种情况的需要。
在一个实施例中，以双面透明广告电视为例子进行说明，由于屏幕两边都是透明地，当要显示文字信息的时候势必造成一面看见是正常的文字，另外一边却看见是镜像的文字，要实现两边看见同样的文字信息。示例性地，如图5c所示，图5c为本发明一实施例接收的图形信息的另一示意图，图5c中显示的是白底红字的“95”字，当广告电视的正面看见的是白底红字的“95”字，而背面则看见白底红字的镜像，如图5d所示，图5d为图5c中显示图形信息的镜像图像的示意图，图5d中显示的是镜像的“95”字样，不利于用户的识别和记忆。示例性的，在发送如图5d所示的图片信息到显示屏，即背后的用户看见如图5e所示的图片，图5e为一种用户在显示屏背后看到的显示屏呈现图像的示意图，如图5e所示周围为黑色中间为白色参杂红色的“95”图案，虽然有颜色参杂其中，但不影响用户的辨识和记忆。在实现透明显示器，实现科技感的同时，实现了前后两端的信息同时显示的效果。
步骤S203、根据所述各像素对应的透明度值控制所述LCD液晶板进行光线处理。
由上述可知，通过上述的显示屏控制方法，可以合理的保护用户隐私、显示设置的图形，在实现科技感的同时，可以实现后两端的信息同时显示的效果。
图6为本发明实施例提供的另一种显示屏控制方法的流程图，给出了一种自动同步模式下的显示屏控制方法。如图5所示，具体包括：
步骤S301、确定显示屏当前透明度和显示模式，所述显示模式包括外部设置模式和自动同步模式。
步骤S302、当确定出所述显示模式为自动同步模式时，接收所述自发光显示屏当前显示信息，根据所述当前透明度和所述自发光显示屏当前显示信息确定所述LCD液晶板各像素对应的透明度值。
一个实施例中，以透明电视为例子进行说明，当电视背对光源的时候，由于光源会影响电视的成像效果，更加会大幅度减弱黑色的成像效果，影响用户视觉体验。目前显示器是采用红蓝绿三原色表示，即RGB颜色体系，R、G和B分量的取值范围为0-255；而现有的透明OLED技术则为图像越暗，对应的自发光能力越弱，透光度越高，于是专门针对黑色选择了应用于印刷技术的CMYK颜色体系，其中C、M、Y和K的取值范围为0.0-1.0，K分量表示黑色，并且RGB和CMYK可以互相转换。示例性地，收到的发光显示屏当前显示信息从当前RGB颜色空间转换为CMYKA颜色空间，由于RGB颜色空间缺少A分量，则先把RGB转换为CMYK，再以K分量为参考对象通过查表得到A分量的值。于是A即为对应像素点的透明度。示例性地，当某个像素点为暗红色，其值为RGB＝[90,48,48]，从数值可以看出对应的OLED发射的能力比较低，在背光下容易被背光穿透，于是，把RGB转换为CMYK得到[0.4,0.66,0.53,0.57]，并且根据K的值查得A的值为0.43，则CMYKA＝[0.4,0.66,0.53,0.57,0.43]，于是，与这个点对应的LCD的透明值为A＝0.43，则该点只允许43％的光线通过LCD液晶板，实现了针对该像素的光线遮挡。实现的显示效果是在OLED有色彩显示的自发亮像素点并且其正背后对应的LCD液晶板会出现透明度相对的灰度颜色，在成像绚丽画面的同时，可以抵挡背光的干扰，并且还能实现透明显示的视觉效果。
示例性地，当某个像素点为黑色，其值为RGB＝[1,1,1]，则OLED的色彩晶元发光非常微弱，对于现有的透明OLED显示屏则可以允许几乎全部背光通过，因此无法实现黑色效果；在使用本专利的情况下，把RGB转换为CMYK得到[0.63,0.52,0.51,0.98]，并且根据K查得A的值为0.02，则CMYKA＝[0.63,0.52,0.51,0.98,0.02]，于是，与这个点对应的LCD的透明值为A＝0.02，则该点允许2％光线通过LCD液晶板，针对该像素的光线遮挡实现了纯黑色。实现的显示效果是在OLED有色彩显示的自发亮像素点并且其正背后对应的LCD液晶板会出现透明度相对的灰度颜色，在成像绚丽画面的同时，可以抵挡背光的干扰，并且还能实现透明显示的视觉效果。
示例性地，当某个像素点为透明，对于现有的透明OLED显示屏，其值为RGB＝[0,0,0]，则OLED的色彩晶 元不发光，但现有的透明OLED不发光就是透明，则可以允许背光全部通过；在使用本专利的情况下，把RGB转换为CMYK得到[0.63,0.52,0.51,1.0]，并且根据K查得A的值为1.0，则CMYKA＝[0.63,0.52,0.51,1.0,1.0]，于是，与这个点对应的LCD的透明值为A＝1.0，则该点允许100％光线通过LCD液晶板，针对该像素的光线实现了透明的效果，兼容现有的透明屏幕效果。实现的显示效果是在OLED有色彩显示的自发亮像素点并且其正背后对应的LCD液晶板会出现透明度相对的灰度颜色，在成像绚丽画面的同时，可以抵挡背光的干扰，并且还能实现透明显示的视觉效果。
一个实施例中，以透明电视为例子进行说明，当电视背对光源的时候，由于光源会影响电视的成像效果，更加会大幅度减弱黑色的成像效果，影响用户视觉体验。进一步的可以接收自发光显示屏当前显示信息。当改进显示颜色体系技术，从原来的RGB变为RGBA颜色体系后，示例性地，收到的发光显示屏当前显示信息后，从当前RGBA颜色空间提取A分量的值，即为对应像素点的透明度。通过原生A分量可以实现更丰富多彩的成像效果，在OLED有色彩显示的自发亮像素点的正背后对应的LCD液晶板会出现透明度相对的灰度颜色，在成像绚丽画面的同时，可以抵挡背光的干扰，并且还能实现透明显示的视觉效果。需要说明的时，还可以根据实际使用场景选择不同的颜色空间模型(例如灰度模型、HSB模型、lab模型等)，在此不再赘述。
一个实施例中，以视频聊天为了进行说明，现有的视频聊天技术都是基于不透明的显示技术，聊天的时候可以看见对方周围的景物，于是跟自身周边的景物形成对比，不但没有科技感，并且会有跟当前环境不相融的感觉，体验感比较差。采用本发明，在视频聊天的视频播放前，通过人工智能技术检测人脸和身体的位置，并人脸和身体部分设置为不透明其值为0.0，则其中一个象素点用RGBA表示则为[R1,G1,B1,0.0]，其他部分设置为透明其值为1.0，其中一个象素用RGBA表示则为[0,0,0,1.0]。在视频聊天的视频播放的时候，当象素点为人脸或身体部分的时候，由于RGBA的A分量为0.0，则为不透明，于是人脸和身体部分能正常播放，当然可以根据需求设置透明度；当象素点为其他部分的时候，其RGBA为[0,0,0,1.0]，则表示OLED显示屏该对应象素点的R、G、B均不发亮，并且A分量为1.0则为LCD液晶板对应象素点的透光率为100％，于是，该象素点的显示效果为透明。采用本发明的显示视觉效果，视频播放效果则为只显示视频拍摄一方的人脸和身体，周围环境为透明，不但能实现跟视频播放一方的背景完全融合的视觉效果，并且实现强烈的科技感。
一个实施例中，以汽车挡风玻璃导航进行说明，如果挡风玻璃使用透明显示屏，则会受外界光线的影响，使显示效果大打折扣。采用本发明，在挡风玻璃设置感光器件并采集车外和车内的光照强度，在不影响驾车安全、不遮挡驾驶员视觉和尽量减少外近光线的干扰的策略下，车载***根据所确认的当前车外光照强度、车外光照强度和导航信息重要性确定显示内容的颜色和透明度，OLEC显示屏根据导航信息各像素点的RGBA中RGB信息显示彩色的导航内容，LCD液晶板则根据导航信息各象素点的RGBA中A分量对应的透明度进行光照强度控制，并且在没有信息提示区域的像素点的RGBA为[0,0,0,1.0]，即表示OLED显示屏该对应象素点的R、G、B晶元均不发亮，并且A分量为1.0则为LCD液晶板对应象素点为的透光率为100％，实现透明效果。如图6a所示，图6a为挡风玻璃使用透明显示屏的智能导航显示效果示意图，图中可以看见挡风玻璃大部分区域为显示透明，则驾驶员可以看见实际路况，配合导航***，根据实际路况的显示相关导航信息，并且使用适当的透明度，确保在不受外界光线干扰的情况下，可以显示导航信息，保证驾驶员的驾驶视觉，保证驾驶安全。
一个实施例中，以汽车挡风玻璃导航进行说明，当外界光线较强的时候，导航***可以适当降低光线通过率，例如把透明区域像素点的透明度降低，如其RGBA为[0,0,0,0.6]，则透明区域的光线通过率为60％，拦截40％的强光，从而降低因强光带来的视觉疲劳，减少安全事故的发生。
一个实施例中，以汽车挡风玻璃导航进行说明，当太阳直射眼睛的时候，可以只针对太阳的象素使其大大降低其透明度，如其RGBA为[0,0,0,0.1]，则遮挡了90％的阳光，可以看见太阳的轮廓，但不受太阳光直射的影响，避免安全事故发生。如图6b所示，图6b为本发明实施例提供的一个场景下的环境光显示示意图，从图中可见整体光线比较亮，并且图中镜头正对太阳，相对刺眼。如图6c所示，图6c为本发明实施例提供的为对图6b的拍摄图像进行调整后的效果示意图，为便于观察和理解，使用了超大规格的晶元来表示。图6c中可以看见太阳光被遮挡了，为体现更直观的效果，除遮挡区域的其他区域光线通过率均为100％，可见整个画面变得更加柔和舒适，避免了太阳直射的刺眼，保证行车安全。本实施例提供了针对不同光照环境的应对方法，使挡风玻璃可以更好适应各种环境，保证驾驶安全。
步骤S303、根据所述各像素对应的透明度值控制所述LCD液晶板进行光线处理。
