具体实施方式
实施例一
图1是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以及至少两个控制器120;所述显示模块110,包括至少两层显示面板111;所述至少两个控制器120分别与所述显示模块110中所述至少两层显示面板111一一对应相连,所述至少两个控制器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,不会被该处于下层的任一显示面板上层的多个显示面板影响,以确保下层显示面板的显示效果。
多个控制器120与多个显示面板111可以是通过总线的方式进行连接。
在实际的使用过程中,在一显示面板111难以正常显示或不能满足用户的显示需求时,通过不同的控制器120控制不同的显示面板111进行显示切换,以提高用户的使用体验。
在上述实施例的技术方案的基础上,在一实施例中,显示模块110中的所包含的至少两层显示面板111中,不同的显示面板具备不同的功耗。
在实际的使用过程中,通过控制器120的控制,有效切换不同功耗的显示面板111对相关信息进行显示,使得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。
在一实施例中,在图2中示出了实施例一提供的另一种显示装置的结构示意图,其中,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;所述控制器包括:主控制器221以及从控制器222;所述主控制器221与所述第一显示面板211相连,所述从控制器222与所述第二显示面板212相连;所述主控制器221设置为在工作状态下,控制所述第一显示面板211进行显示;所述从控制器222设置为在工作状态下,控制所述第二显示面板212进行显示。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,在没有必要采用功耗较大的第一显示面板211显示显示装置中的相关信息时,从控制器222处于工作状态,并控制第二显示面板212进行显示;在具备较高显示要求时,例如要求分辨率高于预设值时,主控制器221处于工作状态,控制第一显示面板211进行显示。上述显示装置的使用,实现了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。
在图2中的显示装置中所示的显示模块的基础上,在一实施例中,图3中示出了实施例一提供的另一种显示模块的结构示意图,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包括:有机发光显示面板211;所述第二显示面板212包括:液晶显示面板212。
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,发明人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,可以通过粘合工序,将有机发光显示面板211与液晶显示面板212进行组合构成所述显示模块。
在一实施例中,所述有机发光显示面板211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贴合设置,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。
在一实施例中,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;红色有机发光结构设置为发出红光,绿色有机发光结构设置为发出绿光,蓝色有机发光结构设置为发出蓝光。
在一实施例中,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(Active-matrix organic light emitting diode,AMOLED)面板。
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。
相关技术中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。
在一实施例中,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。
技术人员通过实验发现,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,例如,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中包括的所述金属层324贴合设置,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。
在图3中所示的显示模块的基础上,在一实施例中,图4中示出了实施例一提供的另一种显示模块的结构示意图,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,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。
在图3中所示的显示模块的基础上,在一实施例中,图5中示出了实施例一提供的另一种显示模块的结构示意图,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与所述主控制器(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主控制器。
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。
在图2中所示的显示装置的基础上,在一实施例中,图6中示出了实施例一提供的另一种显示装置的结构示意图。在该显示装置中,所述主控制器221与所述从控制器222相连:
所述主控制器221,设置为在由工作状态切换至休眠状态时,触发所述从控制器222进入工作状态;以及,在由休眠状态切换至工作状态时,触发所述从控制器222进入休眠状态。
在一实施例中,主控制器221与从控制器222通信连接。其中,当没有必要采用具有高功耗的第一显示面板211进行显示时,主控制器221由工作状态切换至休眠状态,同时触发从控制器222由休眠状态进入工作状态,此时第二显示面板212进行显示,第一显示面板211不显示。当第二显示面板212的显示效果达不到显示需求时,主控制器221由休眠状态切换至工作状态,同时触发从控制器222由工作状态进入休眠状态,此时第一显示面板211进行显示,第二显示面板212不显示。
在实际的应用过程中,通过主控制器221直接或间接控制第一显示面板211和第二显示面板212是否进行显示,实现了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。
在一实施例中,在所述主控制器221中运行有主操作系统,在所述从控制器222中运行有从操作系统,所述从操作系统的功耗小于所述主操作系统的功耗。
在一实施例中,所述主操作系统为Android操作系统,所述从操作系统为实时操作系统(Real Time Operating System,RTOS)。其中,RTOS的功耗小于Android操作系统。
在实际的应用过程中,主控制器221通过Android操作系统控制主控制器221在工作状态和休眠状态之间进行切换,并在工作状态时,控制第一显示面板211对显示装置中的相关信息加以显示。主控制器221还设置为触发从控制器 222,以控制从控制器222在工作状态和休眠状态之间进行切换。其中,从控制器222在工作状态时,通过RTOS控制第二显示面板212对显示装置中的相关信息加以显示。
在没有必要采用高功耗的第一显示面板211对显示装置中的相关信息加以显示时,通过采用低功耗的第二显示面板212显示显示装置中的相关信息能够减少显示装置功耗。另外,采用功耗小于Android操作系统的RTOS控制第二显示面板212进行相应的数据处理并显示显示装置中的相关信息,也降低了显示装置的功能损耗,从而进一步延长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,所述显示装置包括:智能手表或者智能手环。
实施例二
图7是实施例二中的一种显示装置的结构示意图,该显示装置在上述多个实施例的技术方案的基础上,还包括温度传感器230,所述温度传感器230与所述主控制器221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主控制器221;
所述主控制器221,根据所述环境温度,联合所述从控制器222控制所述第一显示面板211以及所述第二显示面板212进行分时显示。
在实际应用过程中,如果显示装置周围环境的环境温度过高,那么第一显示面板211和第二显示面板212所构成的显示模块210的响应速度较快,导致在进行第一显示面板211与第二显示面板212两者之间切换显示时,存在两个显示面板均不显示的情况,也即一个显示面板已经关闭,而另一个显示面板尚未点亮唤醒,致使产生空白显示的情况;如果显示装置周围环境的环境温度较低,那么第一显示面板211和第二显示面板212所构成的显示模块210的响应速度变慢,导致在进行第一显示面板211与第二显示面板212两者之间切换显示时,存在两个显示面板同时显示的情况,也即一个显示面板显示内容尚未消退,而另一个显示面板已经点亮唤醒,致使出现叠影显示的情况。
因此,需要在上述多个实施例的技术方案的基础上,添加温度传感器230检测显示装置周围环境的环境温度,并通过主控制器221接收温度传感器230检测的环境温度,联合从控制器222控制第一显示面板211和第二显示面板212 进行分时显示。
温度传感器230可以为靠近最外侧显示面板设置,以便提高检测显示装置周围环境温度的可信度。
在一实施例中,主控制器221获取温度传感器230检测的环境温度,并在显示装置处于高温情况下,根据环境温度与两个显示面板切换时间的对应关系缩小切换时间,以避免一个显示面板已经关闭,而另一个显示面板尚未点亮唤醒所造成的空白显示的情况;当显示装置在低温情况下,根据环境温度与两个显示面板切换时间的对应关系延长切换时间,以避免一个显示面板显示内容尚未消退,而另一个显示面板已经点亮唤醒所造成的叠影现象。
在一实施例中,所述显示装置包括:智能手表或者智能手环。
实施例三
本实施例还提供了一种电子设备,该电子设备包括上述任一实施例所提供的显示装置。
实施例四
图8是实施例四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进行分时显示的情况,该方法可以由屏幕显示控制装置来执行,该装置由软件和硬件中的至少一个来实现,并配置于由任一实施例提供的显示装置所构成的电子设备(例如可以是智能手表或智能手环等智能可穿戴设备)中,该方法包括以下步骤:S11O-S120。
S110中,主控制器在由工作状态切换至休眠状态时,向相连接的第一显示面板发送屏幕关闭指示,并触发从控制器从休眠状态切换至工作状态。
S120中,所述主控制器在由休眠状态切换至工作状态时,向相连接的第一显示面板发送屏幕开启指示,并触发所述从控制器从工作状态切换至休眠状态。
其中,在所述从控制器从休眠状态切换至工作状态时,向相连接的第二显示面板发送屏幕开启指示,在所述从控制器从工作状态切换至休眠状态时,向相连接的第二显示面板发送屏幕关闭指示。
本实施例通过主控制器或从控制器控制第一显示面板或第二显示面板切换至工作状态或休眠状态,能够在一个显示面板出现问题难以正常显示时,通过 显示面板的切换,保证显示装置能够正常工作,以增强用户的使用体验。
很多设备采用有机显示面板作为显示屏幕,有机发光二极管因其较为轻薄、彩色显示效果较好,广泛应用于电子设备的显示装置中,尤其是对于可穿戴设备,OLED显示屏是较好的选择。而只用OLED作为显示屏幕也存在一个问题就是提高了系统功耗。在智能终端的使用过程中,会存在一些应用场景下,只需要少量信息的显示。示例性地,用户在佩戴可穿戴设备的时候去参加户外运动,一般情况下只需要显示时间、日期或者步数等相关内容,并不需要其他信息,如果一直采用OLED显示会产生一些不必要的耗电量,在无法充电的情况下,就会影响用户的使用。针对这一问题,本实施例采用的是由液晶显示面板和有机发光面板构成的双面屏,在OLED屏的上方覆盖一个TN屏。TN屏是一种低廉、应用最广泛的入门级液晶面板,在目前市面上主流的中低端液晶显示器中被广泛使用。改良型的TN+film,film即补偿膜,用于弥补TN面板可视角度的不足,目前改良的TN面板的可视角度都达到160°。当然这是厂商在对比度为10∶1的情况下测得的极限值,实际上在对比度下降到100∶1时图像已经出现失真甚至偏色。由于TN屏的成本较低,因此,采用这种双面屏具备较高的性价比。可选的,可以采用格式化超扭曲向列显示面板即FSTN型液晶屏和有源矩阵有机发光二极体即AMOLED屏幕。AMOLED具备自发光的特性,同时具备一定的柔韧性,色域较广,并且非常薄,在应用于可穿戴设备时具有特有的优势。
结合上述多个实施例所提供的显示装置以及显示模块的结构示意图,对上述屏幕显示控制方法的多个步骤进行详细说明。
在使用显示装置时,用户可以根据自身的需求选择进行显示的显示面板,显示装置的处理系统也可以根据实际的情况进行显示面板的切换。在没有必要采用高功耗的第一显示面板211显示显示装置中的相关信息时,主控制器221由工作状态切换至休眠状态,同时,主控制器221向第一显示面板211发送屏幕关闭指示,并触发从控制器222从休眠状态切换至工作状态。相应的,从控制器222向相连接的第二显示面板212发送屏幕开启指示,以由第二显示面板212显示显示装置中的相关信息。
在低功耗的第二显示面板212的显示效果难以满足用户的需求时,主控制器221由休眠状态切换至工作状态,同时,主控制器221向第一显示面板211发送屏幕开启指示,并触发从控制器222从工作状态切换至休眠状态。相应的,从控制器222向相连接的第二显示面板发送屏幕关闭指示,以由第一显示面板 211显示显示装置中的相关信息。
可以理解的是,在显示装置正常上电工作时,主控制器221和从控制器222交替处于工作状态和休眠状态中,也即当主控制器221处于工作状态时,从控制器222处于休眠状态;当主控制器221处于休眠状态时,从控制器222处于工作状态。主控制器221和从控制器222分工明确,交替进行显示装置的系统控制,避免了显示装置显示出现混乱。
本实施例对S110和S120的执行顺序不做限定,其中S110可以在S120之前执行,也可以在S120之后执行。
当主控制器221由工作状态切换至休眠状态时,则说明具备使用低功耗的第二显示面板212(示例性地,第二显示面板212为液晶显示面板)的需求。由于液晶显示面板进行显示可以降低功耗,因此可以在不需要显示过多内容时选择液晶显示面板。可选的,主控制器221由工作状态切换至休眠状态的触发条件包括下列任意一种:检测到用户输入操作指令选择使用第二显示面板212、检测到所述显示装置处于运动模式或充电模式、检测到显示装置的光照强度不低于预设强度阈值以及检测到显示装置待机的时间长度超过预设时间阈值。
主控制器221由休眠状态切换至工作状态的触发条件包括下列任意一种:检测到用户输入操作指令选择使用第一显示面板211(示例性地,第一显示面板可以是有机显示面板)和检测到的用户触发事件的复杂度超过预设复杂度阈值。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液晶显示面板212作为显示屏幕,连续两次摇晃手臂对应用户想要选择有机显示面板211作为显示屏幕等。也可以是用户通过显示装置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。也可以按照显示装置所处模式进行屏幕的切换,例如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,则可以切换至采用液晶显示面板212进行显示。
另外,由于TN屏具备如下特性:随着光照强度的增加,显示画面的对比度越高。也就是在黑白显示的时候,显示的画面越清晰。而OLED屏在环境光的光照强度较大时,需要将屏幕亮度调成较大值,这种情况会产生很大的电量消耗,因此,可以在光照强度较高时,采用TN屏进行显示,可以将光照强度超出预设光强阈值作为主控制器221由工作状态切换至休眠状态的触发条件,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。可以将用户触发事件的复杂度超过预设复杂度阈值作为主控制器221由休眠状态切换至工作状态的触发条件。
另外,还可以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,例如用户通过智能手环使用微信聊天的情况下等,就需要利用OLED屏进行显示。
上述OLED屏可以作为第一显示面板211,上述TN屏可以作为第二显示面板212。
本实施例通过主控制器在由工作状态切换至休眠状态时,向相连接的第一显示面板发送屏幕关闭指示,并触发从控制器从休眠状态切换至工作状态;从控制器控制第二显示面板开启;在主控制器由休眠状态切换至工作状态时,向相连的第一显示面板发送屏幕开启指示,并触发从控制器从工作状态切换至休眠状态;从控制器控制第二显示面板关闭。采用上述技术方案解决了显示装置功耗高、待机时间短的技术问题,实现了在满足显示需求的情况下,延长显示装置的待机时长,达到了节能和降低功耗的效果,也可以根据用户自身的意愿选择进行显示的屏幕,提升了用户体验,使产品更贴近用户的实际需求。
在上述多个技术方案的基础上,在一实施例中,在所述主控制器221触发从控制器222进入工作状态之后,还包括:
所述主控制器221向所述从控制器222发送基础显示信息,所述基础显示信息为所述从控制器222进入工作状态后,控制所述第二显示面板212进行显示的信息;
其中,所述基础显示信息包括下述至少一项:系统时间、系统日期以及体征数据。其中体征数据可以为运动步数以及心率等。
在上述多个技术方案的基础上,在一实施例中,主控制器221如果在休眠状态下接收到触摸屏214发送的触摸位置信息,则由休眠状态切换至工作状态。
当在主控制器221处于休眠状态时,如果用户触摸显示装置的触摸屏214,显示装置的主控制器221将会接收到触摸屏214发送的触摸位置信息,此时主 控制器221需要对触摸位置进行定位等操作,因此与触摸屏214相连的主控制器221将由休眠状态切换至工作状态。
