Description

显示装置、电子设备以及屏幕显示控制方法 技术领域
本公开涉及显示技术领域，例如涉及一种显示装置、电子设备以及屏幕显示控制方法。
背景技术
随着用户对具备显示屏幕的电子设备特别是智能穿戴设备使用频率的增强，用户对电子设备待机时长的要求也逐渐提高，以便在不方便充电的情况下不影响电子设备的使用。当前部分电子设备的显示装置采用至少两层功耗不同的显示面板切换的方式，实现在无需高视觉显示需求的情况下采用低功耗显示面板显示电子设备中的相关信息，以降低电子设备的不必要功耗，间接提高电子设备的待机时长。
然而，在对显示装置中的多层显示面板切换时，由于显示装置受所处周边环境温度的影响，会给用户带来较差的使用体验。具体的，在周边环境温度较高时，由于多层显示面板的响应速度变快，使得屏幕切换期间会出现一个显示面板已经关闭，而另一显示面板尚未点亮唤醒，以致出现空白显示的情况；在周边环境温度较低时，由于多层显示面板的响应速度变慢，使得屏幕切换期间会出现一个显示面板显示内容尚未消退，而另一显示面板已经点亮唤醒，以致出现显示叠影的情况。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。

具体实施方式
相关技术中，存在通过选择一个合适的时间窗来兼顾高温以及低温情况下 的进行切换的显示面板的响应速度。然而上述方法却不能有效的解决在不同环境温度下显示装置切换显示面板时出现空白显示或显示叠影的情况。针对该问题，一些实施例提供了一种显示装置。
实施例一
图1为实施例一提供的一种显示装置的结构示意图，该显示装置包括：显示模块110、控制器120以及温度传感器130；所述显示模块110，包括至少两层显示面板111，即多个显示面板111；所述温度传感器130与所述控制器120相连，所述控制器120分别与所述显示模块110中的所述多个显示面板111相连；所述温度传感器130，设置为检测周围环境的环境温度，并将所述环境温度发送至所述控制器120；所述控制器120，设置为根据所述环境温度，控制各所述显示面板111进行分时显示。
其中，对图1中的控制器120的数量可以为一个，也可以为至少两个。当存在至少两个控制器120时，不同的所述控制器120分别与显示模块110中不同的所述显示面板111相连，至少两个控制器120设置为在各自的工作状态下，控制相连接的显示面板111进行显示。
不同的显示面板111可以通过粘合工序组合构成显示模块110。此外，粘合后处于显示模块上层的显示面板具有较高的透明度，使得采用处于下层的任一显示面板进行信息显示时，不会被上层的显示面板影响，以确保下层显示面板的显示效果。
控制器120与多个显示面板111可以是但不限于通过总线的方式进行连接；对温度传感器130的安装位置不做任何限定，可以为贴合显示模块110设置。
在实际的使用过程中，根据温度传感器130检测的周围环境的环境温度，控制器120控制多个不同功耗的显示面板111进行分时显示，并在切换多个显示面板111的过程中，通过调整被切换显示面板与目标切换显示面板的开启和关闭时间，解决了在不同环境温度下显示装置在切换显示面板时出现空白显示或显示叠影的情况，增强了用户的视觉体验。
多个显示面板111的功耗可以相同，也可以不同。示例性地，当多个显示面板111的功耗不同时，所构成的显示模块110在满足用户显示需求的情况下，通过较高功耗的显示面板向较低功耗的显示面板之间的切换，减少了显示装置不必要的显示功耗，延长了显示装置的待机时长，达到节能和降低功耗的效果。
在一实施例中，在图2中示出了实施例一提供的一种具体的显示装置的结构 示意图，其中，显示模块210、控制器220以及温度传感器230；所述显示模块210包括：第一显示面板211以及第二显示面板212，所述第一显示面板211的出光面设置于所述第二显示面板212背离出光面的一侧，所述第二显示面板212的功耗小于所述第一显示面板211的功耗；所述温度传感器230与所述控制器220相连，所述控制器220分别与所述显示模块210中的第一显示面板211和第二显示面板212相连；所述温度传感器230，设置为检测周围环境的环境温度，并将所述环境温度发送至所述控制器220；所述控制器220，设置为根据所述环境温度，控制第一显示面板211和第二显示面板212进行分时显示。其中，第二显示面板212具备较高的透明度，使得在第一显示面板211进行显示时，能够确保第一显示面板211的显示效果。
在实际使用过程中，温度传感器230在检测周围环境的环境温度之后，将该环境温度发送至控制器220；控制器220根据该环境温度，控制高功耗的第一显示面板211以及低功耗的第二显示面板212进行分时显示。并且，在进行第一显示面板211与第二显示面板212切换显示的过程中，通过调整被切换显示面板与目标切换显示面板的开启和关闭时间，解决了在不同环境温度下显示装置在切换显示面板时出现空白显示或显示叠影的情况，增强了用户的视觉体验。同时，还在满足用户显示需求的情况下，减少了显示装置不必要的功耗，延长了显示装置的待机时长，达到节能和降低功耗的效果。
图2所示的显示装置的基础上，还可以将控制器220扩展为两个。当存在两个控制器220时，一个控制器220与第一显示面板211通过总线或者其他方式相连，以控制第一显示面板211的开启或者关闭；另一个控制器220与第二显示面板212通过总线或者其他方式相连，以控制第二显示面板212的开启或关闭。其中，温度传感器230分别与两个控制器220相连。当温度传感器230检测到周边环境的环境温度时，将环境温度分别发送至多个控制器220。其中，一个控制器220在第一时间节点控制第一显示面板211的开启或关闭；在第一时间节点的基础上添加一个特定的时间差确定第二时间节点，另一个控制器220在该第二时间节点控制第二显示面板211的关闭或开启。时间差可以是正值也可以是负值，第二时间节点的确定可以通过任一控制器220来实现。
在上述多个实施例的技术方案提供的显示装置的基础上，在一实施例中，图3示出了多个显示装置所包含的一种显示模块和温度传感器的结构示意图。其中显示模块210包括：第一显示面板211和第二显示面板212。
所述第一显示面板211为有机发光显示面板，所述第二显示面板212为液晶显示面板。
其中，有机发光显示面板211与液晶显示面板212在分时显示时互不干扰，所述液晶显示面板212应该为透明面板，且不包括背光源，因为如果该液晶显示面板212包括背光源的话，则会对下层的有机发光显示面板211进行遮挡。同时，为了能够使液晶显示面板212能够正常进行显示，有机发光显示面板211需要为其提供背光源。考虑到有机发光显示面板211一般包括有金属层作为金属阴极，技术人员创造性的提出使用机发光显示面板211中的该金属层作为液晶显示面板212使用的背光源，通过上述巧妙的设置，可以实现双显示面板的分时显示。
在一实施例中，所述有机发光显示面板211具体包括：
第一基板310；
位于所述第一基板310一侧的阵列排布的有机发光结构320；
所述有机发光结构320包括：依次层叠设置的空穴传输层321、有机发光层322、电子传输层323和金属层324。
其中，液晶显示面板212与有机发光显示面板211中包括的金属层324贴近设置，以直接使用金属层324作为液晶显示面板212的背光源。环境光照射至金属层324，环境光经过金属层324反射，由经过金属层324反射的环境光为液晶显示面板212提供光源。
其中，有机发光结构320包括红色有机发光结构、绿色有机发光结构和蓝色有机发光结构；红色有机发光结构发出红光，绿色有机发光结构发出绿光，蓝色有机发光结构发出蓝光。
具体的，由于红色有机发光结构、绿色有机发光结构或者蓝色有机发光结构在点亮后的亮度不同，点亮的种类不同(仅点亮一个或者两个有机发光结构，或者点亮全部有机发光结构)，导致有机发光结构320以彩色呈现。有机发光结构320的发光属于注入型发光。简单地说是由阴极注入的电子和阳极注入的空穴在发光层相互作用形成受激的激子，激子从激发态回到基态时，将其能量差以光子的形式释放出来。
在一实施例中，有机发光显示面板110可以包括：有源矩阵有机发光二极体面板(Active-matrix organic light emitting diode，AMOLED)。
AMOLED的基础是有机物发光体，成千上万个只能发出红色、绿色或蓝色这三者颜色之中的一种的光源被以一种特定的形式安放在屏幕的基板上，这些 发光体在被施加电压的时候会发出红、绿或者蓝色，电压的变换同样需要依靠薄膜晶体管(Thin Film Transistor，TNT)，在调节三原色的比例之后，才能发出多种颜色。
OLED，即有机发光二极管，又称为有机电致发光器件，其基本结构包括对应每个像素区域的阳极、阴极和发光层，当电压被施加到阳极与阴极上时，空穴通过空穴传输层移动至发光层，电子通过电子传输层移动至发光层，二者在发光层中复合，发光层材料中的激子由激发态迁移到基态发光。不同颜色的有机发光结构对应不同的发光层材料，不同颜色有机发光结构各自对应的发光层材料在有机发光结构的阳极电压和阴极电压的作用下，分别发出不同颜色的光。
市面上已经出现了多款比较成熟的AMOLED产品，这类产品为了滤除杂波，增加AMOLED的显示对比度，一般在AMOLED中的金属层的上部，再贴合一层圆偏光片，因此，为了减少本实施例的实现工序，节约开发成本，在本实施例中，可以在已有AMOLED产品的基础上，摘除该圆偏光片，以直接作为本实施例的有机发光显示面板211。
示例性的，可以是在购买厂商的AMOLED屏时直接提出需求，使生产厂商在生产过程中减少贴合圆偏光片这一道工序，可直接获得不包含圆偏光片的AMOLED屏，也即该有机发光显示面板211。在本实施例中，AMOLED构成的有机发光显示面板211能够实现彩色显示，液晶显示面板212能够实现黑白显示，例如可以是，若用户只需要显示时间和日期，则可以通过液晶显示面板212进行显示，若用户需要显示微信，则可以通过有机发光显示面板211进行显示。
发明人通过实验发现，通过对一些无需彩色显示的内容使用液晶显示面板212进行显示，能够在最大程度上降低功耗，节约电量，特别是，针对一些电池容量比较小，续航时间比较短的显示装置所构成的电子设备，例如：智能手表或者智能手环等，上述显示模块210的引入所能起的作用也更大。
一般来说，液晶显示面板212的造价都比较便宜，本实施例的方案通过引入液晶显示面板212，能够在不明显增加生产成本的基础上，大大改善所配置设备的功耗，可以带来明显的用户体验改善以及产品竞争力。
在一实施例中，所述液晶显示面板212具体包括：依次层叠设置的第二基板330、液晶层340和第三基板350；
其中，所述第二基板330与所述有机发光显示面板211中包括的所述金属层324贴近设置，所述第二基板330以及所述第三基板350为透明材质。
通过上述设置，液晶显示面板212整体为一个透明面板，因此在下层的有机发光显示面板211工作时，液晶显示面板212对其的影响最小。虽然会一定程度上牺牲掉有机发光显示面板211显示对比度以及色彩饱和度，但是上述牺牲可以以软件的方式进行补偿。
液晶显示面板212可以包括膜补偿超扭曲向列(Film Compensation Super Twisted Nematic，FSTN)显示面板。
这种液晶显示面板212的外面通常含有一层补偿膜，这层补偿膜通常由聚合物制成，也具有双折射性。当o光和e光通过补偿膜时，将会产生附加相位差，使o光和e光的相位得以延迟或补偿，从而改变偏振光的干涉色。FSTN中的补偿膜可以位于偏光片的下面，也可以位于偏光片的上面，可以用一片，也可以用两片。有些两片补偿膜系统下面的这片还同时起到准直器的作用，上面这片补偿膜同时具备散射膜的作用，以便增加液晶显示器的视角还不影响液晶显示器的响应速度。
对比度与视角的关系FSTN是薄膜补偿的STN(Super Twisted Nematic，STN)，可实现黑白显示。FSTN对高分子薄膜的延迟量和方向有严格要求。与黄绿模式STN相比，黄绿模式FSTN的视角特性和对比度要好的多，对比度大于5的等高线包涵的区域也宽得多。对比度大于10的区域也比黄绿模式STN的大。
结合图3所示的显示模块和温度传感器的结构示意图，温度传感器230可以设置在显示装置中的任何位置，优选为贴近液晶显示面板212进行设置。当然，还可以通过在第三基板350中通过嵌入粘合的方式安装一温度传感器230，但这样可能由于复杂的工艺流程而增加制作显示面板210的成本。图3仅示例性地给出了在不改变显示模块210的物理结构的基础上贴近液晶显示面板212设置温度传感器230的一种情况。
在图3中所示的显示模块和温度传感器的基础上，在一实施例中，图4中示出了本实施例一提供的另一种显示模块和温度传感器的结构示意图，该显示模块210还包括透明玻璃213，所述透明玻璃213设置于所述第二显示面板212的出光面所在的一侧。
通过在显示模块210中设置透明玻璃213，以对显示装置中的第一显示面板211和第二显示面板212起到了保护作用。
示例性地，图4示出了通过在透明玻璃213中通过嵌入粘合的方式安装一温度传感器230的技术方案。温度传感器230还可以通过嵌入粘合的方式安装在第 一基板310、有机发光结构320、第二基板330、液晶层340或者第三基板350中。当然，为了简化制作显示模块210的工艺流程以及制作成本，也可以在贴近第一基板310的位置进行设置。示例性地，在不影响显示装置外观以及不妨碍用户使用的情况下，还可以将温度传感器230安装在显示模块210中的出光面侧，以便增强温度传感器230检测的周边环境的环境温度的可信度。
在图3中所示的显示模块和温度传感器的基础上，在一实施例中，图5中示出了本实施例一提供的另一种显示模块和温度传感器的结构示意图，显示模块210还包括：触摸屏214，所述触摸屏214设置于所述第二显示面板212的出光面所在的一侧；所述触摸屏214与所述控制器(图中未示出)相连；
所述触摸屏214，设置为获取触摸位置信息，并将所述触摸位置信息发送至所述控制器。
通过在显示模块210中设置触摸屏214，以实现用户与显示装置的交互，使用户操作显示装置更加便捷。
示例性地，图5示出了通过在触摸屏214中通过嵌入粘合的方式安装一温度传感器230的技术方案。温度传感器230还可以通过嵌入粘合的方式安装在第一基板310、有机发光结构320、第二基板330、液晶层340或者第三基板350中。当然，为了简化制作显示模块210的工艺流程以及制作成本，也可以在贴近第一基板310的位置进行设置。示例性地，在不影响显示装置外观以及不妨碍用户使用的情况下，还可以将温度传感器230安装在显示模块210中的出光面侧，以便增强温度传感器230检测的周边环境的环境温度的可信度。
在上述多个实施例的技术方案的基础上，所述显示装置包括：智能手环或智能手表。
在上述多个实施例的技术方案的基础上，所述显示装置中所包含的控制器可以为两个，具体连接方式已在本实施例的前述技术方案中进行披露，在此不再赘述。
实施例二
本实施例二还提供了一种电子设备，该电子设备包括上述任一实施例的技术方案所提供的显示装置。
实施例三
图6是实施例三提供的一种屏幕显示控制方法的流程示意图，本实施例可适用于采用任一实施例提供的显示装置在一定的周边环境下通过切换多个显示面 板进行分时显示的情况。该方法可以由屏幕控制装置来执行，该装置由软件和硬件中的至少一个来实现，并配置于显示装置中，该方法包括以下内容：S110-S140。S110中，在检测到满足屏幕切换条件时，获取环境温度。
在该步骤中，在控制器检测到满足屏幕切换条件时，控制器获取温度传感器检测的周围环境的环境温度。
屏幕切换条件可以包括下列任意一种：检测到用户输入操作指令选择使用某一显示面板、检测到所述显示装置进行了模式切换(例如从一般模式切换至充电模式)、检测到显示装置的光照强度与预设强度阈值的大小关系发生变化以及检测到显示装置待机的时间长度超过预设时间阈值、检测到的用户触发事件的复杂度与预设复杂度阈值的大小关系发生变化(例如，触发事件的复杂度超过最高复杂阈值，或者触发事件的复杂度低于最低复杂阈值)等。
其中，用户的输入操作可以是用户输入的体感手势，例如可以是抬手腕、摇晃手臂等，也可以对不同次数的体感手势进行不同的定义，例如单次摇晃手臂对应用户想要选择某一显示面板作为显示屏幕，连续两次摇晃手臂对应用户想要选择另一显示面板作为显示屏幕等。也可以是用户通过电子设备上的机械按键进行指令的输入，示例性地，可以通过智能手表的表冠进行指令的输入。
其中，检测到所述显示装置进行了模式切换可以是以下情况：当智能手环处于运动模式或充电模式时，用户没有查看应用软件等需求，则可以切换至低功耗的显示面板进行显示。
其中，检测到显示装置待机的时间长度超过预设时间阈值进行显示面板的切换是指：在光照强度大于预设强度阈值时，表示当前环境光的光照强度较大，需要屏幕亮度偏高，因此需要采用低功耗的显示面板进行显示以减少显示装置的电量损耗；在光照强度不大于预设强度阈值时，表示当前环境光的光照强度较小，需要屏幕亮度偏低，因此可以采用高功耗的显示面板进行显示。其中，预设光强阈值可以根据显示面板的属性进行调整，也可以根据实际需求进行设定。
其中，检测到的用户触发事件的复杂度与预设复杂度阈值的大小关系发生变化可以为：预先对所有能够产生的触发事件进行复杂度评估，按照需要显示的画面的复杂程度确定复杂度，触发事件可以是查看时间、听音乐或广播、打开应用程序等。可以将“查看时间”、“查看天气”等事件定义为复杂度较低的事件；“打开应用程序”定义为复杂度较高的事件等。当事件的复杂度超过预设 复杂度阈值时，说明该事件对显示的需求较高，需要采用高功耗的显示面板进行显示；当事件的辅助度不超过预设复杂阈值时，说明该事件对显示的需求较低，因此可以采用低功耗的显示面板进行显示。
S120中，根据所述环境温度，确定第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差。
本实施例中的第一显示面板和第二显示面板与上述多个实施例中的第一显示面板和第二显示面板并不相同。本实施例中的第一显示面板为当前正在正常显示的显示面板，也即被切换显示面板。本实施例中的第二显示面板为即将用于显示的显示面板，也即目标切换显示面板。
其中，控制器可以根据环境温度确定第一显示面板与第二显示面板的时间差。具体的，时间差为第一显示面板的关闭时间与第二显示面板的开启时间。其中，时间差可以是正值，也可以是负值。
示例性地，如果第一显示面板的响应时间小于第二显示面板的响应时间，那么时间差为负值；如果第一显示面板的响应时间大于第二显示面板的响应时间，那么时间差为正值。
S130中，根据所述时间差，确定所述第一显示面板的关闭时间以及所述第二显示面板的开启时间。
在该步骤中，如果时间差为正值，在控制器获取时间差之后将由控制器向第一显示面板发送关闭指令，以控制第一显示面板关闭显示，并将发送关闭指令这一时刻确定为关闭时间。控制器根据关闭时间以及时间差通过加和的方式确定关闭时间之后的开启时间，后续将由控制器在开启时间向第二显示面板发送开启指令，以控制第二显示面板开启显示。
如果时间差为负值，在控制器获取时间差之后将有控制器向第二显示面板发送开启指令，以控制第二显示面板开启显示，并将发送开启指令的这一时刻确定为开启时间。控制器根据开启时间与时间差通过作差的方式确定开启时间之后的关闭时间，后续将由控制器在关闭时间向第一显示面板发送关闭指令，以控制第一显示面板关闭显示。
S140中，在到达所述关闭时间时，关闭所述第一显示面板，以及，在达到所述开启时间时，开启所述第二显示面板。
本实施例通过在检测到满足屏幕切换条件时获取温度传感器检测的环境温度；根据该环境温度确定第一显示面板的关闭时间与第二显示面板的开启时间 之间的时间差；根据该时间差确定第一显示面板的关闭时间以及第二显示面板的开启时间；在到达关闭时间时，关闭第一显示面板，以及在到达开启时间时，开启第二显示面板，以控制多个显示面板进行分时显示。采用上述技术方案解决了在不同环境温度下显示装置在切换显示面板时出现空白显示或显示叠影的情况，增强了用户的视觉体验。
在上述实施例的技术方案的基础上，在一实施例中，根据所述环境温度，确定第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差，包括：
根据所述环境温度以及预设的时间差对应关系，确定第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差。
其中，预设的时间差对应关系可以通过进行大量的实验测试获取环境温度和与环境温度相对应的时间差，并通过数据拟合的方式确定环境温度以及时间差之间的计算公式，并将该计算公式作为预设的时间差对应关系。控制器可以将温度传感器检测的环境温度作为预设的时间差计算公式的输入变量，最终确定与该环境温度相对应的时间差。其中，该时间差具体为第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差。
在上述实施例的技术方案的基础上，在一实施例中，不同的切换关系对应不同的时间差计算公式；
所述切换关系由所述第一显示面板以及所述第二显示面板的面板类型确定。所述切换关系对应如下：当第一显示面板为有机发光显示面板，第二显示面板为液晶显示面板时，将由有机发光显示面板切换至液晶显示面板的切换关系确定为第一切换关系；当第一显示面板为液晶显示面板，第二显示面板为有机发光显示面板时，将由液晶显示面板切换至有机发光显示面板的切换关系确定为第二切换关系。
有机发光显示面板的响应时间小于液晶显示面板的响应时间。同时，多个显示面板，特别是液晶显示面板由开启到关闭和由关闭到开启的响应时间存在差异。因此，由有机发光显示面板切换至液晶显示面板的第一切换关系所对应的预设的时间差对应关系与由液晶显示面板切换至有机发光显示面板的第二切换关系所对应的预设的时间差对应关系并不相同。相应的，在执行上述S120中根据环境温度确实时间差时，控制器会根据切换关系选择对应的预设的时间差计算公式。
实施例四
图7是实施例四提供的一种屏幕显示控制装置的结构示意图，本实施例可适用于采用任一实施例提供的显示装置在一定的周边环境下通过切换多个显示面板进行分时显示的情况。该装置包括：温度获取模块410、时间差确定模块420、切换时间确定模块430以及显示控制模块440。
其中，温度获取模块410，设置为在检测到满足屏幕切换条件时，获取环境温度；
时间差确定模块420，设置为根据所述环境温度，确定第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差；

在上述实施例的技术方案的基础上，在一实施例中，所述时间差确定模块420，包括：
时间差确定单元，设置为根据所述环境温度以及预设的时间差对应关系，确定第一显示面板的关闭时间与第二显示面板的开启时间之间的时间差。
在上述实施例的技术方案的基础上，在一实施例中，不同的切换关系对应不同的时间差计算公式；
所述切换关系由所述第一显示面板以及所述第二显示面板的面板类型确定。
上述屏幕显示控制装置可执行任意实施例所提供的屏幕显示控制方法，具备执行屏幕显示控制方法相应的功能模块和有益效果。
