附图说明

图2示出了本发明实施例一的一种保护盖板的结构示意图之二;
图3示出了本发明实施例二的一种平视显示器的保护装置的结构示意图;
图4示出了本发明实施例三的一种平视显示器的保护方法的步骤流程图。
具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。
实施例一
参照图1,示出了本发明实施例提供的一种保护盖板的结构示意图。所述保护盖板10包括层叠设置的前盖板101、变色层102和后盖板103;
所述变色层102中设置有电致变色材料,所述变色层102,被配置为在电场的作用下调整透光率,以保护平视显示器。
本实施例中,保护盖板10包括前盖板101、变色层102和后盖板103,变色层102中含有电致变色材料,电致变色材料可以在电场的作用下调整变色层102的透光率。例如,在无电场时,变色层102可以透过可见光和红外光,透光率大于95%;在电场较弱时,变色层102只能透过可见光,透光率约为50%;在电场较强时,可见光和红外光均无法透过变色层102,变色层102的透光率低于10%。保护盖板10放置在平视显示器上,通过变色层102调整透光率,可以避免平视显示器被强光照射而导致的老化或损坏,起到保护平视显示器的作用。
可选地,参照图2所示的保护盖板的结构示意图,所述变色层102包括相对设置的第一电极1021和第二电极wo,以及位于所述第一电极1021和所述第二电极1022之间的电解质层1023;
所述电解质层1023中含有所述电致变色材料;
所述电致变色材料在所述电场的作用下吸附到所述第一电极1021或所述第二电极1022上,以改变所述变色层102的透光率。
本实施例中,可以将第一电极1021设置为阳极,第二电极1022设置为阴极;也可以将第一电极1021设置为阴极,第二电极1022设置为阳极。本发明实施例对此不作详细限定,可以根据实际情况进行设置。通过第一电极1021和第二电极1022可以产生电场,电解质层1023中的电致变色材料在电场的作用下吸附到第一电极1021或第二电极1022上。例如,电致变色材料在电场的作用下吸附到阴极上。当电场较弱时,吸附到阴极上的电致变色材料较少,则变色层102的透光率较高;当电场较强时,吸附到阴极上的电致变色材料较多,则变色层102的透光率较低。
可选地,所述电致变色材料包括无机电致变色材料和有机电致变色材料;
所述无机电致变色材料包括三氧化钨;
所述有机电致变色材料包括聚噻吩、聚噻吩类衍生物、紫罗精类、四硫富瓦烯、金属酞菁类化合物中的至少一种。
本发明实施例对电致变色材料不作详细限定,可以根据实际情况进行选取。
可选地,所述前盖板和所述后盖板均为透明材质;
所述透明材质包括玻璃、亚克力中的至少一种。
综上所述,本发明实施例中,保护盖板包括层叠设置的前盖板、变色层和后盖板;变色层中设置有电致变色材料,电致变色材料在电场的作用下调整变色层的透光率,可以避免平视显示器被强光照射而导致的老化或损坏,起到保护平视显示器的作用,延长了平视显示器的寿命,提高了用户的使用体验。
实施例二
参照图3,示出了本发明实施例提供了一种平视显示器的保护装置的结构示意图。所述平视显示器包括如实施例一所述的保护盖板10及与所述保护盖板10的变色层102耦接的控制模块20;
所述控制模块20,被配置为向所述变色层102输入控制信号,控制所述变色层102产生的电场。
本实施例中,平视显示器的保护装置包括保护盖板10和控制模块20,控制模块20与保护盖板10的变色层102耦接。控制模块20可以向变色层102输入控制信号,变色层102根据控制信号产生电场,从而使变色层102中的电致变色材料吸附到第一电极1021或第二电极1022上。控制模块20通过控制变色层102产生的电场,可以调整变色层102的透光率,从而避免平视显示器被强光照射,进而保护平视显示器。
可选地,所述控制模块20,被配置为判断平视显示器的当前状态是否满足预设条件,若满足所述预设条件,则控制所述电场,以调整所述变色层102的透光率;
其中,所述预设条件包括所述平视显示器处于非工作状态且光照强度大于预设值。
本实施例中,控制模块20在控制变色层102产生的电场时,先判断是否需要调整保护盖板10的透光率对平视显示器进行保护,即判断平视显示器的当前状态是否满足预设条件。具体地,判断平视显示器是否处于非工作状态,判断光照强度是否大于预设值。如果平视显示器处于非工作状态,并且光照强度大于预设值,则表明需要对平视显示器进行保护。此时,控制变色层102的电场,降低变色层102的透光率,避免平视显示器被强光照射。
可选地,所述非工作状态包括所述平视显示器处于关闭状态,所述平视显示器所在的车辆处于停止行驶状态中的至少一种。
本实施例中,平视显示器的非工作状态可以是平视显示器处于关闭状态。例如,无需平视显示器辅助驾驶时,用户关闭了平视显示器。非工作状态还可以是车辆处于停止状态。例如,车速为0,或者是发动机关闭时,也不需要平视显示器辅助。此时可以控制变色层102降低透光率,对平视显示器进行保护。
综上所述,本发明实施例中,平视显示器的保护装置包括保护盖板和控制模块,控制模块向保护盖板的变色层输入控制信号,控制变色层产生的电场,从而调整保护盖板的透光率,进而保护平视显示器,避免平视显示器被强光照射而老化或损坏,延长了平视显示器的寿命,提高了用户的使用体验。
实施例三
参照图4,示出了本发明实施例提供的一种平视显示器的保护方法的步骤流程图。应用于如实施例二所述的平视显示器的保护装置,所述方法包括:
步骤301,判断平视显示器的当前状态是否满足预设条件;其中,所述预设条件包括所述平视显示器处于非工作状态且光照强度大于预设值。
本实施例中,首先判断平视显示器的当前状态是否满足预设条件,即判断是否需要对平视显示器进行保护。具体地,判断平视显示器是否处于非工作状态,判断光照强度是否大于预设值;如果平视显示器处于非工作状态,且光照强度大于预设值,则判定平视显示器的当前状态满足预设条件。如果平视显示器处于工作状态,或者光照强度不大于预设值,则判定平视显示器的当前状态不满足预设条件。本发明实施例对光照强度不作详细限定,可以根据实际情况进行设置。
可选地,所述非工作状态包括所述平视显示器处于关闭状态,所述平视显示器所在的车辆处于停止行驶状态中的至少一种。
例如,用户关闭了平视显示器,或者是平视显示器所在的车辆的车速为0,又或者是车辆的发动机关闭,则平视显示器处于非工作状态。本发明实施例对非工作状态不作详细限定,可以根据实际情况进行设置。
步骤302,若满足所述预设条件,则调整所述保护装置的透光率,以保护所述平视显示器。
本实施例中,如果平视显示器的当前状态满足预设条件,则需要对平视显示器进行保护,因此调整保护装置的透光率,使部分光线无法照射到平视显示器上,从而避免平视显示器被强光照射而老化或损坏,延长了平视显示器的寿命,提高了用户的使用体验。
可选地,若不满足所述预设条件,将所述保护装置的透光率调整为初始值。
具体地,平视显示器处于工作状态,或者光照强度低于预设值,则将保护装置的透光率调整为初始值。初始值可以是透光率大于90%,也可以是透光率大于80%,本发明实施例对初始值不作详细限定,可以根据实际情况进行设置。
综上所述,本发明实施例中,判断平视显示器的当前状态是否满足预设条件,若满足预设条件,则调整保护装置的透光率,以保护平视显示器,避免平视显示器被强光照射而老化或损坏,延长了平视显示器的寿命,提高了用户的使用体验。
本说明书中的各个实施例均采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似的部分互相参见即可。
最后,还需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
以上对本发明所提供的一种保护盖板、平视显示器的保护装置和保护方法,进行了详细介绍,本文中应用了具体个例对本发明的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本发明的方法及其核心思想;同时,对于本领域的一般技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本发明的限制。
