为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，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。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
请参阅图1，本发明第一实施例的提供一种电子装置10，电子装置10包括显示面板100、感光器件200及处理器300，所述显示面板100包括有机电 致发光器件110和电致变色吸收层120，电致变色吸收层120设于有机电致发光器件110的一侧。其中电致变色吸收层120能够在被施加不同的电压后改变其透光率的大小，具体的，可以是施加不同的电压后其颜色发生变化，进而改变其透光率。可以理解的是，显示面板100、感光器件200与处理器300之间电连接，其中处理器300与有机电致发光器件110、电致变色吸收层120电连接。
感光器件200能够接收外界光的照射，并且感测照射到显示面板100上的外界光线强度，并且将该强度信息发送至处理器300，处理器300根据照射到显示面板100上的外界光线强度调整电致变色吸收层120的透光率以及有机电致发光器件110的发光强度。例如，当感光器件200感测到外界光线强度较低时，也就是电子装置10处于外界光线较暗的环境中时，感光器件200将感测到此时的外界光线强度信息发送至处理器300，处理器300根据此时的外界光线强度，将电致变色吸收层120的透光率变大，因而有机电致发光器件110只需要更低的亮度即可实现高对比度。可以理解的是，当电致变色吸收层120的透光率调整后，还可以根据显示面板100的显示效果需求，调整有机电致发光器件110的发光强度。例如，当电致变色吸收层120的透光率调整变大后，由于其具有较大的透光率，有机电致发光器件110发出的光同样从电致变色吸收层120发出时具有较大的透光率，在光线较弱的环境中，仅需要更低的发光亮度，所以可以降低有机电致发光器件110的发光强度，进而更加节能，同时使有机电致发光器件110寿命得以延长。
本发明提供的电子装置10能够根据外界光线强度变化来调整电致变色吸收层的透光率，进而可取代现有的偏光片，且在光线较弱时，能够降低有机电致发光器件的发光强度，降低电子装置能耗，延长器件使用寿命。
请参阅图2，在进一步的实施例中，电子装置10还包括存储器400，存储 器400存储有不同的外界光线强度与电致变色吸收层120的透光率及有机电致发光器件110的发光强度的对应关系。其中存储器400与处理器300电连接。当感光器件200感测到显示面板100上的外界光线强度为第一光线强度时，处理器300将第一光线强度与存储器400里的存储的外界光线强度进行比较，当第一光线强度与存储器400里存储的外界光线强度中的第一外界光线强度匹配时，处理器300读取与第一外界光线强度对应的电致变色吸收层120的第一透光率及有机电致发光器件110的第一发光强度，并调整电致变色吸收层120的透光率为第一透光率，且调整有机电致发光器件110的发光强度为第一发光强度。
在进一步的实施例中，当感测器件200感测到显示面板100上的外界光线强度与第一光线强度的差值在预设范围内时，处理器300将电致变色吸收层120的透光率设为第一透光率，且调整有机电致发光器件110的发光强度设为第一发光强度。也就是说，显示面板100上的外界光线强度在一定范围内变化时，处理器300对电致变色吸收层120和有机电致发光器件110不作改变，这样可以避免外界光线强度在较小范围内改变时处理器300不停响应工作而导致性能下降或者过度消耗电子装置10的电量。
在进一步的实施例中，存储器400中不同的外界光线强度与电致变色吸收层120的透光率的对应关系记为第一对应关系，存储器400中不同的外界光线强度与有机电致发光器件110的发光强度的对应关系记为第二对应关系。
其中，第一对应关系的获取方法包括如下步骤。将有机电致发光器件110设为黑态，感光器件200获取外界光线强度，处理器300根据外界光线强度调整电致变色吸收层120的透光率至预设透光率，使得反射亮度达到预设值，不同的外界光线强度和与其相对应的预设透光率形成第一对应关系。其中黑态是指有机电致发光器件110没有被点亮时的状态。有机电致发光器件110为黑态 时，外界光线在有机电致发光器件110黑态时反射相较于其他亮度时反射，致使显示对比度最低，将该预设透光率作为参考值适用于非黑态时的有机电致发光器件110时，能够提高显示对比度。
其中，第二对应关系的获取方法包括如下步骤。将有机电致发光器件110设为白态，处理器300根据感光器件200在有机电致发光器件110设为黑态时所获取的外界光线强度调整有机电致发光器件110的发光强度至预设发光光强，不同的外界光线强度和与其相对应的预设发光光强形成第二对应关系。其中白态是指有机电致发光器件110被点亮时的状态。当有机电致发光器件110为白态时，根据外界光线的强弱，动态调整电致变色层的透光率，使反射亮度达到预设值，再根据电致变色吸收层120的透光率改变有机电致发光器件110的亮度，使得达到理想的对比度。光线较弱的环境中，只需要较低的发光亮度，在此情况下通过调整有机电致发光器件110的发光强度至预设发光光强，降低发光亮度，可进一步节能，延长器件寿命。
在进一步的实施例中，处理器300根据感光器件200感测到的外界光线强度的变化得到外界光线强度变化的频率，当外界光线强度的变化频率大于预设频率的时候，处理器300保持当前电致变色吸收层的120透光率以及当前有机电致发光器件110的发光强度。当电子装置10处于外界光线强度的变化频率较大时，如果处理器300根据不断变换的外界光线强度不停地响应切换电致变色吸收层120的透光率及有机电致发光器件110的发光强度，会导致处理器300工作负荷过重，且容易导致处理器300、电致变色吸收层120及有机电致发光器件110的性能下降，还容易过快消耗掉电量。因此，在该实施例中，当外界光线强度的变化频率大于预设频率的时候，处理器300保持当前状态，有利于避免处理器300、电致变色吸收层120及有机电致发光器件110的性能下降，还能节能。
在进一步的实施例中，当电子装置10的电量小于预设电量时，处理器300保持当前电致变色吸收层120的透光率，且处理器300根据电子装置10的电量调整有机电致发光器件110的发光强度小于预设值。当电子装置10的电量较低时，如果处理器300仍然根据外界光线强度变化来响应切换电致变色吸收层120的透光率及有机电致发光器件110的发光强度，会导致电子装置10的电量被提前消耗殆尽，而没有足够维持本身显示的电量，导致显示时间变短。因此，在该实施例中，当电子装置10的电量小于预设电量时，处理器300进行上述操作，可以节约电子装置的电量，进而延长电子装置10的显示时间。
请参阅图3，本发明第二实施例提供一种电子装置10a，在电子装置10a中，显示面板100还包括触控电极层130，触控电极层130设于电致变色吸收层120远离有机电致发光器件110的表面上。优选的，在该实施例中，触控电极层130是透明电极层。
在进一步的实施例中，显示面板100还包括覆盖层140，覆盖层140设于电致变色吸收层110远离触控电极层130的表面上。优选的，覆盖层140是透明的。在该实施例中，有机电致发光器件110发出的光自覆盖层140出射。外界光线自覆盖层140远离触控电极层130的表面入射。
请参阅图4，本发明第三实施例的提供一种电子装置10b，在电子装置10b中，显示面板100中的触控电极层130设于有机电致发光器件110的一侧，电致变色吸收层120设于触控电极层130远离有机电致发光器件110的表面上。
在进一步的实施例中，显示面板100还包括覆盖层140，覆盖层140设于触控电极层130远离电致变色吸收层120的表面上。在该实施例中，有机电致发光器件110发出的光自覆盖层140射出，外界光线自覆盖层140远离电致变色吸收层120的表面入射。将电致变色吸收层120设于触控电极层130之上，可以吸收自触控电极层130远离有机电致发光器件110的表面上反射的光线。
在进一步的实施例中，电致变色吸收层120从上至下依次包括第一基底层121、第一透明导电层122、电致变色层123、电解质层124、离子存储层125、第二透明导电层126及第二基底层127，其中覆盖层140设于第一基底层121远离第一透明导电层122的表面上，第二基底层127设于触控电极层130远离有机电致发光器件110的表面上。其中第一基底层12及第二基底层127优选为玻璃或透明基底层。在该实施例中，优选的，覆盖层140的材料与第一基底层121的材料相同，或者触控电极层130的材料与第二基底层127的材料相同，以降低界面间的反射率，提高显示画面的对比度。
电致变色吸收层120工作时，在第一透明导电层122及第二透明导电层126之间加上一定的电压，电致变色层123中的电致变色材料在电压作用下发生氧化还原反应，颜色发生变化。第一透明导电层122或者第二透明导电层126一起构成电致变色吸收层120上下两个透明电极，通常采用的透明氧化铟锡，掺铝氧化锌膜等。离子存储层125在电致变色层123中的电致变色材料发生氧化还原反应时起到储存相应的反离子，保持整个体系电荷平衡的作用，离子存储层125也可以为一种与前面一层电致变色层123中的电致变色材料变色性能相反的电致变色材料，这样可以起到颜色叠加或互补的作用。电解质层124用于提供电致变色层123补偿离子，以平衡电致变色层123电荷平衡。
可以理解的是，第三实施例中的电致变色吸收层120同样适用于其他实施例。
请参阅图5，本发明第四实施例提供的一种电子装置10c，在电子装置10c中，显示面板100包括显示区150和非显示区160，显示区150包括阵列分布的子显示区151，有机电致发光器件110设于子显示区151内，有机电致发光器件110还包括阳极111、发光层112及阴极113，发光层112设置在阳极111的表面上，阴极113设置在发光层112远离阳极111的表面上且位于子显示区 151内，电致变色吸收层120设于阴极113远离发光层112的一侧。阴极113用于将自电致变色吸收层120入射的外界光线反射，所述阴极113图案化而使阴极113的面积占显示区150预设比例以使自电致变色吸收层120对应的显示区150内入射的外界光线在阴极113上的反射率小于预设值，相邻的子显示区151内的阴极113之间存在间隙114。
请参阅图6外界光线在电子装置10c中的线路图。相邻的子显示区151内的阴极113之间存在间隙114，使得部分外界光线(记为L1)入射到阴极113表面上后被反射，部分外界光线(L2)入射到间隙114内而不被反射，从而降低外界光线在阴极113上的反射率，例如入射到电致变色吸收层120的外界光线为L，入射到阴极113表面被阴极113反射的光线为L1,L1与L的强度比值即为反射率，被反射的外界光线越小，反射率越低。因此，可以通过阴极113图案化与电致变色吸收层120的透光率调节相结合，进一步提高电子装置10c在不同外界光线强度情况下的显示对比度。
可以理解的是，在每个子显示区151内的阴极113可进行图案化设置，进一步减少阴极113的面积占显示区150的预设比例，进一步降低阴极113的反射率。
请参阅图7，本发明还提供一种电子装置10的控制方法的实施例，电子装置10包括显示面板100，显示面板100包括有机电致发光器件110和电致变色吸收层120，电致变色吸收层120设于有机电致发光器件110的一侧，电子装置10的控制方法包括步骤S100及步骤S200。详细步骤如下所述。
步骤S100，检测照射到显示面板100上的外界光线强度。可以理解的是，可以采用感光器件感测外界光线。
步骤S200，根据照射到显示面板100上的外界光线强度调整电致变色吸收层120的透光率以及有机电致发光器件110的发光强度。
本发明提供的电子装置10的控制方法根据外界光线强度变化来调整电致变色吸收层120的透光率以及有机电致发光器件110的发光强度，进而实现电子装置10在不同外界光线强度情况下保持较高的对比度，且同时能够节能，延长器件使用寿命。
在进一步的实施例中，当显示面板100上的外界光线强度为第一光线强度时，将第一光线强度与预存的外界光线强度进行比较，当第一光线强度与预存的外界光线强度中的第一外界光线强度匹配时，读取与第一外界光线强度对应的电致变色吸收层120的第一透光率及有机电致发光器件110的第一发光强度，并调整电致变色吸收层120的透光率为第一透光率，且调整有机电致发光器件110的发光强度为第一发光强度。
在进一步的实施例中，当显示面板100上的外界光线强度与第一光线强度的差值在预设范围内时，调整电致变色吸收层120的透光率设为第一透光率，且调整有机电致发光器件110的发光强度设为第一发光强度。有利于外界光线强度在较小范围内改变时，避免电致变色吸收层120及有机电致发光器件110不断调整而导致性能下降。
在进一步的实施例中，第一外界光线强度与第一外界光线强度对应的电致变色吸收层的第一透光率之间的对应关系记为第一对应关系，第一外界光线强度与第一外界光线强度对应的有机电致发光器件的第一发光强度之间的对应关系记为第二对应关系。
其中，第一对应关系的获取方法包括如下步骤。将有机电致发光器件110设为黑态，根据外界光线强度调整电致变色吸收层120的透光率至预设透光率，使得反射亮度达到预设值，不同的外界光线强度和与其相对应的预设透光率形成第一对应关系。有机电致发光器件110为黑态时，外界光线在有机电致发光器件110黑态时反射相较于其他亮度时反射，致使显示对比度最低，因此在黑 态下设置得到相对应的预设透光率不仅可以提高在黑态时的显示对比度，将该预设透光率作为参考值适用于非黑态时的有机电致发光器件110时，能够提高显示对比度。
其中，第二对应关系的获取方法包括如下步骤。将有机电致发光器件110设为白态，根据有机电致发光器件110设为黑态时的外界光线强度调整有机电致发光器件110的发光强度至预设发光光强，不同的外界光线强度和与其相对应的预设发光光强形成第二对应关系。当有机电致发光器件110为白态时，根据外界光线的强弱，动态调整电致变色吸收层120的透光率，使反射亮度达到预设值，再根据电致变色吸收层120的透光率改变有机电致发光器件110的亮度，使得达到理想的对比度。光线较弱的环境中，只需要较低的发光亮度，在此情况下通过调整有机电致发光器件110的发光强度至预设发光光强，降低发光亮度，可进一步节能，延长器件寿命。
在进一步的实施例中，当外界光线强度的变化频率大于预设频率的时候，保持当前电致变色吸收层120的透光率以及当前有机电致发光器件110的发光强度。当外界光线强度的变化频率大于预设频率的时候，电致变色吸收层120及有机电致发光器件110保持当前状态，有利于避免电致变色吸收层120的透过率及有机电致发光器件110的发光光强持续变化而导致性能下降，还能节能。
在进一步的实施例中，当电子装置的电量小于预设电量时，保持当前电致变色吸收层120的透光率，且根据电子装置的电量调整有机电致发光器件110的发光强度小于预设值。当电子装置10的电量小于预设电量时，采用上述方法，可以节约电子装置的电量，进而延长电子装置10的显示时间。
本发明还提供一种计算机可读存储介质的实施例，计算机可读存储介质存储了用于电子装置10的控制的程序，其中，程序被执行的时候执行上述任意一项实施例的控制方法。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
