具体实施方式
为使本公开实施例要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
在下面的描述中,提供诸如具体的配置和组件的特定细节仅仅是为了帮 助全面理解本公开的实施例。因此,本领域技术人员应该清楚,可以对这里描述的实施例进行各种改变和修改而不脱离本公开实施例的范围和精神。另外,为了清楚和简洁,省略了对已知功能和构造的描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
针对传统的显示屏幕因可视角度过大,而使显示内容易被非使用者窥视的问题,本公开实施例提供多种解决方案。
一方面,本公开的实施例提供一种屏幕可视角度的控制方法,如图1所示,包括:
步骤101,捕获视线落入柔性屏幕的显示区域内的观看者;
步骤102,确定观看者相对于显示区域内的观看角度;
步骤103,根据该观看角度,确定一卷曲角度;以及
步骤104,控制所述柔性屏幕按照上述卷曲角度进行卷曲。
基于本实施例的控制方法,可以主动识别视线落入显示区域的观看者,并确定观看者相对显示区域的观看角度,从而控制柔性屏幕按照观看角度进行蜷曲,以调整显示区域的可视角度。在实际应用中,可以实现优化显示区域相对于观看者的显示角度,或者控制显示区域对窥视者进行屏蔽。
以优化显示区域相对观看者的显示角度为例,本实施例的上述观看角度具体为:观看者中不需要屏蔽的第二目标观看者相对于显示区域内的观看角度。
在执行上述步骤104时,若显示区域的可视角度不包括该观看角度,则控制柔性屏幕按照卷曲角度进行卷曲,使得显示区域的可视角度包括观看角度。
显然,基于上述设计,本实施例的方法可以控制柔性屏幕主动调整显示角度,以适合观看者进行观看,能够提供更好的观看体验,因此具有很高的实用价值。
具体地,若观看角度为:所述观看者中需要屏蔽其观看的第一目标观看者相对于所述显示区域内的观看角度。
此外,以控制显示区域对窥视者进行屏蔽为例,本实施例的上述观看角度具体为:观看者中需要屏蔽的第一目标观看者相对于显示区域内的观看角度。
在执行上述步骤104时,具体控制柔性屏幕按照确定到的卷曲角度进行卷曲,使得显示区域的可视角度不包括观看角度。
基于上述设计,本实施例的方法可以使柔性屏幕主动识别视线落入显示区域的观看者,并在其中确定出需要屏蔽的对象。之后控制柔性屏幕进行卷曲,以改变显示区域的可视角度,从而让需要屏蔽其观看的对象无法观看显示区域的内容,以实现防窥视的功能。
下面对本实施例实现防窥视的功能进行详细介绍。
示例性地,本实施例在执行上述步骤101时,可以基于人眼识别技术和/或脸部识别技术,捕获视线落入柔性屏幕的显示区域内的观看者。
对于显示产品来讲,摄像头已经是十分普及的部件。因此在实际应用中,本实施例的控制方法可以通过摄像头具体识别人的瞳孔和/或脸部的朝向,并结合显示区域的位置进行比对。但凡是视线有趋势或者视线大致落入柔性屏幕的显示区域内的观看者,都可以再进一步确定是否需要被屏蔽。
当然,在实际情况中,会有一些人无意识的扭头恰好让视线扫到了柔性屏幕的显示区域,而这些人的视线往往只是一瞬时停留在显示区域上。因此,为了避免柔性屏幕不进行过多的无意义的卷曲,相应的在执行步骤102之前,对这些人进行过滤。
因此,在具体执行上述步骤101时,本实施例还可以只捕获视线落入柔性屏幕的显示区域内达到预设时长的观看者,从而更加准确的筛选出对显示区域有窥视意图的目标观看者。
此外本实施例的控制方法还可以进一步在明确确定有窥视者时,再对屏幕进行卷曲。即,在执行上述步骤102时,若视线落入显示区域内的观看者的当前数量大于预设阈值,则从观看者中确定出需要屏蔽的第一目标观看者,之后再确定第一目标观看者相对于显示区域内的观看角度。
在实际应用中,上述预设阈值可以由柔性屏幕所有者进行灵活设置。例如,根据实际需求将预设阈值设置为两个,当确定出有三个以及三个以上的观看者,则确定存在窥视者,并进一步确定可能存在窥视意图的第一目标观看者。
具体地,本实施例的控制方法可以根据一定判断规则,确定出上述目标观看者。作为示例性介绍,在一般情况下,窥视者在窥视的过程中往往要躲过柔性屏幕所有者的注意,因此会与柔性屏幕保持一定距离。相应的,基于该原理,本实施例还可以进一步根据各个观看者与柔性屏幕之间的距离来确定第一目标观看者。
比如,假设当前有五个视线落入显示区域的观看者,而柔性屏幕所有者设置的预设阈值为两个,则此时可能存在三个可能正在窥视显示区域的观看者。因此,本实施例可以将距离相对柔性屏幕最远的三个观看者作为第一目标观看者。
这里需要说明的,以上判断目标观看者的规则仅作为示例性介绍,不应限制本公开实施例的保护范围。此外,观看者与柔性屏幕之间距离可以由现有的传感器实现,由于本公开实施例并不涉及这方面的改进,因此不再举例赘述。
进一步地,本实施例的控制方法在确定目标观看者后,就可以对柔性屏幕进行卷曲。
作为示例性接介绍,在控制柔性屏幕进行卷曲前,本实施例的控制方法可以先确定出目标观看者相对于显示区域的观看位置,在执行上述步骤104时,具体可以控制柔性屏幕在对应观看位置的方向上,按照卷曲角度进行卷曲。
显然,基于上述设计,本实施例可以尽可能减小柔性屏幕执行防窥视时所需要卷曲的面积,从而避免影响柔性屏幕的正常显示。
在实际应用中,假设本实施例的柔性屏幕为手机屏幕,如图2所示,本实施例的控制方法通过手机21的前置摄像头211确定出一个可能有窥视意图的目标观看者22的视线落在了手机21的显示区域212上。之后如图3所示,本实施例的控制方法控制手机21的柔性屏幕在对应目标观看者22的一侧进 行卷曲,例如,手机21的柔性屏幕的短边向上顺时针方向卷曲,卷曲角度为α。另外,本领域技术人员能够理解的是,手机21的柔性屏幕的短边向上逆时针方向卷曲,或者手机21的柔性屏幕的短边还可以向下顺时针方向或者逆时针方向卷曲,或者手机21的柔性屏幕的长边还可以向左或者向右顺时针方向或者逆时针方向进行卷曲。在柔性屏幕卷曲后,显示区域212的可视角度减小,从而使目标观看者22再无法观看到显示区域212的内容,以实现了防窥视的功能。
另一方面,本公开的另一实施例还提供一种屏幕可视角度的控制装置400,如图4所示,包括:
捕获电路401,用于捕获视线落入柔性屏幕的显示区域内的观看者;
观看角度确定电路402,用于确定观看者相对于所述显示区域内的观看角度;
卷曲角度确定电路403,用于根据所述观看角度,确定一卷曲角度;以及
控制电路404,用于控制所述柔性屏幕按照所述卷曲角度进行卷曲。
显然,本实施例的控制装置作为本公开实施例提供的上述控制方法的执行主体,因此该控制方法所能实现的技术效果,本实施例的控制装置同样也能够实现。
具体地,本实施例的捕获电路401可以基于人眼识别技术和/或脸部识别技术,捕获视线落入柔性屏幕的显示区域内的观看者。
对于显示产品来讲,摄像头已经是十分普及的部件。因此在实际应用中,本实施例的捕获电路401可以通过控制显示产品的摄像头,来具体识别人的瞳孔和/或脸部的朝向,并结合显示区域的位置进行比对。但凡是视线有趋势或者视线大致落入柔性屏幕的显示区域内的观看者,都可以在进一步确定是否需要屏蔽。
在实际应用中,本实施例上述的观看角度可以为:观看者中需要屏蔽的第一目标观看者相对于显示区域内的观看角度。
相应的,上述控制电路404用于:
控制柔性屏幕按照确定的卷曲角度进行卷曲,使得显示区域的可视角度 不包括观看角度。
基于上述设计,本实施例的控制装置可以使柔性屏幕主动识别视线落入显示区域的观看者,并在其中确定出需要屏蔽的对象。之后控制柔性屏幕进行卷曲,以改变显示区域的可视角度,从而让需要屏蔽的对象无法观看显示区域的内容,以实现防窥视的功能。
此外,在实际应用中,本实施例上述的观看角度还可以为:观看者中不需要屏蔽的第二目标观看者相对于显示区域内的观看角度。
相应的,上述控制电路404用于:
若所述显示区域的可视角度不包括所述观看角度,则控制柔性屏幕按照卷曲角度进行卷曲,使得显示区域的可视角度包括观看角度。
基于上述设计,本实施例的控制装置可以控制柔性屏幕主动调整显示角度,以适合观看者进行观看,能够提供更好的观看体验,因此具有很高的实用价值。
下面,以控制装置400控制显示区域的可视角度以对窥视者实现屏蔽的应用为例,进行详细介绍。
具体的,如图6所示,本实施例的观看角度确定电路402包括:
第一确定子电路4021,若视线落入显示区域内的观看者的当前数量大于预设阈值,则从观看者中确定出需要屏蔽的目标观看者;以及
第二确定子电路4022,确定目标观看者相对于显示区域内的观看角度。
在实际应用中,上述预设阈值可以由柔性屏幕所有者进行灵活设置。例如根据实际需求将预设阈值设置为两个,当确定出有三个以及三个以上的观看者,则确定存在窥视者,并进一步确定可能存在窥视意图的目标观看者。
此外,如图4所示,本实施例的控制装置400例如还可以包括:
位置确定单元405,用于在控制电路404控制柔性屏幕按照卷曲角度进行卷曲前,确定目标观看者相对于显示区域的观看位置。
具体的,控制电路404用于控制柔性屏幕在对应上述观看位置的方向上,对柔性屏幕靠近窥视者的一侧进行卷曲,从而更有效率地利用较少的卷曲面积,实现防窥视功能,能够尽可能降低卷曲对柔性屏幕显示画面所带来的影响。
此外,本公开的另一实施例还提供一种柔性显示装置,如图5所示,包括:
一柔性屏幕51;
本公开实施例所提供的上述控制装置52;以及
设置在柔性屏幕51上的一个或多个的形变单元53。
其中控制装置52的控制电路用于按照卷曲角度生成激励形变单元53的激励源,该形变单元53在激励源的控制下发生形变,使得柔性屏幕51按照卷曲角度发生卷曲。
本实施例在柔性屏幕设置形变单元,在需要柔性屏幕进行卷曲时,可以实施卷曲位置对应的形变单元发生形变,以带动柔性屏幕进行卷曲。可见,本实施例的柔性显示装置基于本公开实施例所提供的上述控制方法能够实现防窥视功能,可保护用户的隐私,因此具有很高的实用价值。
下面结合实际应用,对本实施例的柔性屏幕进行卷曲的方案进行详细介绍。
实现方式一
在实现方式一中,如图7所示,形变单元由磁流变液710构成,而控制形变单元形变的激励源为磁场720。
其中,控制装置400的控制电路404具体可在形变单元相对应的区域产生一个磁场,该磁流变液710构成的形变单元在磁场(激励源)720的控制下,发生形状的变化,以带动柔性屏幕发生卷曲。
在实际应用中,控制电路404可具体调整磁场720的大小以及方向,以实现对柔性屏幕发生卷曲的精确控制。
实现方式二
在本实现方式二中,如图8所示,形变单元为一弹性腔体830。可选的,所述弹性腔体830是透明弹性腔体。
对应地,控制电路404具体包括:
存储有气体或液体的存储腔810,通过中空管道与弹性腔体830连接;
与弹性腔体830对应设置的微型马达820,用于从存储腔810中抽取气体或液体,并将抽取到的气体或液体输送到弹性腔体830。
即存储腔810中的气体或液体即为能够改变透明弹性腔体830的激励源。
在需要形变单元发生形变时,微型马达820在控制电路404的控制下,抽取存储腔810中的气体或液体,并将抽取的气体或液体通过中空管道(未示出)输送到透明弹性腔体830内,使该弹性腔体830膨胀,以带动柔性屏幕发生卷曲。
在实际应用中,控制电路404可具体调整从存储腔810中抽取气体或液体的剂量,以实现对柔性屏幕发生卷曲的精确控制。
此外,在上述基础之上,作为可选方案,本实施例的柔性显示装置还可以包括有:
提示单元(未示出),当柔性屏幕卷曲以实现防窥视时,无法对窥视者进行有效屏蔽,则可以为用户进行有效提示。该提示单元主要用于:判断柔性屏幕是否能够按照所述卷曲角度发生卷曲,并在确定所述柔性屏幕无法照所述卷曲角度发生卷曲时,控制所述柔性屏幕进行防窥提示(例如在显示区域通过显示画面以提示用户,或者驱动柔性显示装置的震动马达以震动方式提示用户)。
基于本实施例的提示单元的设计,在柔性显示装置无法通过卷曲实现防窥视功能时,还可以及时对使用者进行通知,以让使用者及时采取其他措施保护个人隐私安全。
以上所述是本公开的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本公开实施例所述原理的前提下,还可以作出若干改进和润饰,这些改进和润饰也应视为本公开实施例的保护范围。
