在下文中将参考附图更充分地描述示例实施例,但是所述示例实施例可以以不同形式来体现且不应当被解释为限于本文阐述的实施例。反之,提供这些实施例的目的在于使本公开透彻和完整,并将使本领域技术人员充分理解本公开的范围。
在不冲突的情况下,本公开各实施例及实施例中的各特征可相互组合。
如本文所使用的,术语“和/或”包括一个或多个相关列举条目的任何和所有组合。
本文所使用的术语仅用于描述特定实施例,且不意欲限制本公开。如本文所使用的,单数形式“一个”和“该”也意欲包括复数形式,除非上下文另外清楚指出。还将理解的是,当本说明书中使用术语“包括”和/或“由......制成”时,指定存在所述特征、整体、步骤、操作、元件和/或组件,但不排除存在或添加一个或多个其它特征、整体、步骤、操作、元件、组件和/或其群组。
除非另外限定,否则本文所用的所有术语(包括技术和科学术语)的含义与本领域普通技术人员通常理解的含义相同。还将理解,诸如那些在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开实施例的背景下的含义一致的含义,且将不解释为具有理想化或过度形式上的含义,除非本文明确如此限定。
作为本公开实施例的第一个方面,提供一种显示面板,如图1所示,该显示面板包括第一显示部100,第一显示部100包括多个第一像素单元110,其中,第一像素单元110包括发光元件111和控制元件112,发光元件111和控制元件112沿所述显示面板的厚度方向(图1中的上下方向)依次设置,控制元件112设置为在电场的控制下在透光状态(图1、图2、图5)和遮光状态(图3、图4)之间转换,发光元件111设置为在驱动电压的控制下发光。
需要指出的是,显示面板用在包括第一摄像头300的显示装置中,第一摄像头300与第一显示部100相对设置,且第一摄像头300位于显示面板的背光侧。需要使用第一摄像头300时,向控制元件112施加能够使得该控制元件112处于透光状态的电场,使得显示面板外部的光可以透过控制元件112进入第一摄像头300(参见图5),实现通过第一摄像头300拍照。在不需要使用第一摄像头300进行拍照时,可以向控制元件112施加能够使得该控制元件112处于遮光状态的电场,此时,对于位于显示面板发光侧的用户而言,第一摄像头300是不可见的。由于第一像素单元110还设置有发光元件111,可以通过控制发光元件111的亮度实现 不同灰阶的显示,因此,当控制元件112处于遮光状态时(参见图4),显示面板的第一显示部100可以正常显示。也就是说,在不使用第一摄像头的情况下,所述显示面板可以实现全面屏显示。
在本公开实施例中,对控制元件112的具体结构不做特殊的限定。例如,所述控制元件112可以为液晶盒,在电场的作用下,液晶盒中的液晶分子会发生偏转,从而可以使得液晶盒可以在透光状态和遮光状态之间发生切换。
例如,对于常黑状态的液晶材料而言,当不向控制元件112施加电场时,控制元件112处于遮光状态。当向控制元件112施加预定强度的电场时,控制元件112中的液晶分子发生偏转,使得控制元件112处于透光状态。
再例如,对于常白状态的液晶材料而言,当不向控制元件112施加电场时,控制元件112处于透光状态。当向控制元件112施加预定强度的电场时,控制元件112中的液晶分子发生偏转,使得控制元件112处于遮光状态。
当然,本公开实施例并不限于此。作为一种可选实施方式,如图2和图3中所示,控制元件112包括极性材料层,所述极性材料层包括多个不透光的极性粒子112a,极性粒子112a长度方向的尺寸大于该极性粒子112a其他方向的尺寸。也就是说,极性粒子112a可以具有棒状、针状等细长结构。
在这种实施方式中,如图3中所示,极性粒子112a两端的极性不同,以使得极性粒子112a能够在电场的作用下旋转至使得控制元件112呈现遮光状态的程度,且极性粒子112a还能够在电场的作用下旋转至使得控制元件112呈现透光状态的程度。
在本公开实施例中,对控制元件112的其他部分也不做特殊的限定。例如,控制元件112还可以包括相对设置的第一基板112b和第二基板112c,所述极性材料层设置在第一基板112b和第二基板112c之间。
如图2所示,在透光状态下,极性粒子112a的长度方向与控制元件112的厚度方向一致,以使得光从极性粒子112a之间的间隔中穿过。如图3所示,在遮光状态下,极性粒子112a的长度方向与控制元件112的厚度方向垂直,从而可以对光线进行遮挡。
如上文中所述,第一像素单元110还包括发光元件111,在本公开实施例中,对发光元件111的具体结构不做特殊的限定。例如,发光元件111可以是有机发光二极管(OLED,Organic Light-Emitting Diode)。为了使得整个第一像素单元110发光均匀、提高第一显示部的显示质量,可选地,如图3、图4、图5中所示,第一基板112b设置在发光元件111和第二基板112c之间,第一基板112b朝向发光元件111的表面为内凹表面。如图4所示,当控制元件112处于遮光状态时,第一基板112b的表面形成为凹面镜,发光元件111发出的光照射在第一基板112b的内凹表面上之后,被均匀反射出去,从而可以使得将发光元件111的点光源转换面光源,提供第一像素单元110的发光均匀性,从而提高第一显示部100的显示质量。
为了进一步提高第一像素单元110的发光均匀性,可选地,极性粒子112a包括粒子本体和包覆所述粒子本体的反光层。
当发光元件111发光时,照射在极性粒子112a的反光层上,被朝向显示面板的出光面反射。
作为一种可选实施方式,第一基板112a的内凹表面为弧形面,发光元件111设置在第一基板的内凹表面形成的凹面镜的焦点上,从而可以将发光元件111射向内凹表面的光转换为 平行光,提高第一像素单元110的亮度均匀程度。
在本公开实施例中,对如何将发光元件111设置在第一基板112b的内凹空间内不做特殊的限定。例如,可以在第一基板112b的内凹表面上填充透明树脂材料,并在透明树脂材料上设置发光元件111,再例如,可以设置其他能够支撑发光元件111的支撑元件,只要能够实现将发光元件111设置在第一基板112b的内凹表面对应的空间内即可。
为了提高显示效果、避免相邻第一像素单元110之间互相串色,可选地,相邻两个第一像素单元110之间设置有挡光件120。
在本公开实施例中,对挡光件120的具体材料不做特殊的限定。例如,挡光件120的材料可以是掺杂有炭黑的树脂材料。
在本公开实施例中,对第一显示部100在显示面板中所占的比例不做特殊的限定。作为一种可选实施方式,整个显示面板的显示区域均为第一显示部。为了作为另一种可选实施方式,所述显示面板还包括第二显示部200,该第二显示部200包括多个第二像素单元。需要指出的是,第二像素单元为传统的像素单元。例如,第二像素单元可以为包括OLED的像素单元、也可以为液晶像素单元。
图5中所示的是控制元件112处于透光状态时,显示面板的发光状态示意图。图5中,朝上的箭头表示显示面板的第二显示部200发出的显示光,用于显示画面。朝下的箭头表示环境光(包括被拍摄的物体所反射的光),光线穿过极性粒子112a之间的间隔到达第一摄像头300。如上文中所述,极性粒子112a的外表面为反光表面,当第二像素单元发光时,会照射在极性粒子112a的反光表面上,并被反射,从而可以避免在第一摄像头300拍摄时第二显示部200受周围第二像素单元发光的干扰。
在本公开实施例中,对第一显示部100和第二显示部200的相对位置关系不做特殊的限定,可选地,第二显示部200环绕第一显示部100设置。
为了提高显示面板的整体显示效果,可选地,第一显示部100中第一像素单元110的密度与第二显示部200中第二像素单元的密度相同。
作为本公开实施例的第二个方面,提供显示面板的控制方法,其中,所述显示面板为本公开实施例所提供的上述显示面板,如图6所示,所述控制方法包括:
在步骤S210中,响应于第一拍摄触发信号,向所述第一显示部的各个所述控制元件提供使得各个所述控制元件处于透光状态的电场;
在步骤S220中,响应于第一拍摄结束信号,向所述第一显示部的各个所述控制元件提供使得各个所述控制元件处于遮光状态的电场。
此处的“第一拍摄触发信号”是指能够触发第一摄像头拍摄的信号,该第一拍摄触发信号可以是使用者可以通过诸如触控面板、控制按键等输入装置向第一摄像头提供的信号。在接收到第一拍摄触发信号后,可以向第一显示部的各个所述控制元件提供使得各个所述控制元件处于透光状态的电场,以使得控制元件、以及第一显示部整体处于透光状态,环境光可以透过第一显示部到达第一摄像头。
此处的“第一拍摄结束信号”是表征第一摄像头拍摄结束的信号。使用者也可以通过诸如触控面板、控制按键等输入装置生成所述第一拍摄结束信号。在接收到所述第一拍摄结束信号后,可以向所述第一显示部的各个所述控制元件提供使得各个所述控制元件处于遮光状态的电场,控制元件可以将第一摄像头遮挡住,恢复第一显示部的正常显示功能。
作为本公开实施例的第三个方面,提供一种控制模块,其中,该控制模块设置为控制本公开实施例第一方面所提供的显示面板,所述控制模块设置为:
响应于第一拍摄触发信号,向所述第一显示部的各个所述控制元件提供使得各个所述控制元件处于透光状态的电场;
响应于第一拍摄结束信号,向所述第一显示部的各个所述控制元件提供使得各个所述控制元件处于遮光状态的电场。
作为本公开实施例的第四个方面,提供一种显示装置,所述显示装置包括显示面板、第一摄像头300和控制模块,所述显示面板包括出光面和背光面,其中,所述显示面板为本公开实施例第一个方面所提供的上述显示面板,第一摄像头300设置在与第一显示部100对应的位置,且第一摄像头300与所述背光面相对,所述控制模块为本公开实施例第三个方面所提供的控制模块。
如上文中所述,当需要使用第一摄像头300进行拍摄时,控制模块向控制元件112施加能够使得该控制元件112处于透光状态的电场,使得显示面板外部的光可以透过控制元件112进入第一摄像头300,实现通过第一摄像头300拍照。在不需要使用第一摄像头300进行拍照时,控制模块可以向控制元件112施加能够使得该控制元件112处于遮光状态的电场,此时,对于位于显示面板发光侧的用户而言,第一摄像头300是不可见的。由于第一像素单元110还设置有发光元件111,可以通过控制发光元件111的亮度实现不同灰阶的显示,因此,当控制元件112处于遮光状态时,显示面板的第一显示部100可以正常显示。也就是说,在不使用第一摄像头的情况下,所述显示面板可以实现全面屏显示。
可选地,所述显示装置还可以包括第二摄像头,该第二摄像头用作后置摄像头。
在本公开实施例中,对如何向控制元件提供电场不做特殊的限定,可选地,所述显示装置包括电场提供模块,所述电场提供模块设置为向所述控制元件提供电场。
本文已经公开了示例实施例,并且虽然采用了具体术语,但它们仅用于并仅应当被解释为一般说明性含义,并且不用于限制的目的。在一些实例中,对本领域技术人员显而易见的是,除非另外明确指出,否则可单独使用与特定实施例相结合描述的特征、特性和/或元素,或可与其它实施例相结合描述的特征、特性和/或元件组合使用。因此,本领域技术人员将理解,在不脱离由所附的权利要求阐明的本公开的范围的情况下,可进行各种形式和细节上的改变。
