本发明的实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
具体的,请参阅图1,图1为本申请实施例提供的背光模组的第一结构示
意图,如图1所示,本申请实施例提供的背光模组10a包括第一背光组件101以及第二背光组件102,其中,第一背光组件101和第二背光组件102相对设置,且第二背光组件102包括相对设置的第一侧102a以及第二侧102b,第一背光组件101设置在第一侧102a上;第二背光组件102中部设置有一通孔102c,第一背光组件101覆盖通孔102c。
其中,可以理解的,当第一背光组件101呈背光态时,第一背光组件101发出的光的传播路径会发生改变,以形成均匀面光源,使第一背光组件101作为背光源提供背光;当第一背光组件101呈透明态时,第一背光组件101内外的光可透过第一背光组件101传播,而此时第二背光组件102设置有通孔102c,因此第一背光组件101内外的光也可透过第二背光组件102中的通孔102c传播,此时背光模组10a内外的光可透过背光模组10a传播。
因此,采用第一背光组件101这一结构,不需要在液晶显示面板上预留刘海或开口区域等方式,就可以使液晶显示屏幕内外的光可透过液晶显示面板以及背光模组10a传播;从而可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本的前提下,解决现有设备中液晶显示屏幕难以透光的技术问题。
具体的,请参阅图2,图2为本申请实施例提供的背光模组的第二结构示意图,如图2所示,本申请实施例提供的背光模组10a包括第一背光组件101以及第二背光组件102,其中,第一背光组件101和第二背光组件102相对设置,且第二背光组件102包括相对设置的第一侧102a以及第二侧102b,第一背光组件101设置在第二侧102b上;第二背光组件102中部设置有一通孔102c,第一背光组件101包括第一部分101a以及设置在第一部分101a两端的第二部分101b,其中,第一部分101a与通孔102c相对设置,第一部分101a呈透明态或背光态,第二部分101b呈透明态。
其中,可以理解的,当第一背光组件101呈背光态时,第一背光组件101发出的光的传播路径会发生改变,以形成均匀面光源,使第一背光组件101作为背光源提供背光;当第一背光组件101呈透明态时,第一背光组件101内外的光可透过第一背光组件101传播,而此时第二背光组件102设置有通孔102c,因此第一背光组件101内外的光也可透过第二背光组件102中的通孔102c传播,此时背光模组10a内外的光可透过背光模组10a传播。
具体的,请参阅图3,图3为本申请实施例提供的背光模组的第三结构示意图,如图3所示,本申请实施例提供的背光模组10a包括第一背光组件101以及第二背光组件102,其中,第一背光组件101和第二背光组件102平行设置,且第二背光组件102包括相对设置的第一端以及第二端,第一背光组件101设置在第一端或第二端上。
其中,可以理解的,当第一背光组件101呈背光态时,第一背光组件101发出的光的传播路径会发生改变,以形成均匀面光源,使第一背光组件101作为背光源提供背光;当第一背光组件101呈透明态时,第一背光组件101内外的光可透过第一背光组件101传播,因第二背光组件102与第一背光组件101平行设置,因此第二背光组件102不会影响到第一背光组件101透过第一背光组件101传播,因此背光模组10a内外的光可透过背光模组10a传播。具体的,请参阅图4,图5以及图6,图4为本申请实施例提供的第一背光组件的主视图,图5为本申请实施例提供的第一背光组件的俯视图,图6为本申请实施例提供的第一背光组件的侧视图,如图4,图5,图6所示,本申请实施例提供第一背光组件第一背光组件101包括可调节透明面板1011以及位于可调节透明面板一端的发光二极管灯带1012。
其中,可以理解的,当发光二极管灯带1012打开,且可调节透明面板1011呈背光态时,此时发光二极管灯带1012射向可调节透明面板1011的光的传播路径会发生改变,以形成均匀面光源;其中,可调节透明面板1011呈背光态指的就是此时的可调节透明面板1011可以改变光线的传播路径,能破坏光线的全反射,其中,改变光线的传播路径的状态可以为散射或者衍射等。
其中,可以理解的,当发光二极管灯带1012关闭,且可调节透明面板1011呈透明态时,此时第一背光组件101外的光可以透过可调节透明面板1011传播;其中,可调节透明面板1011呈透明态,指的是此时的可调节透明面板1011是透明的,不可以改变光线的传播路径,也不可以阻挡光线的传播,其中,不改变光线的传播路径不考虑两种均匀透光物质间,因折射率变化而产生的折射、反射等情况。
其中,在一种实施方式中,发光二极管灯带1012通过粘贴的方式固定在可调节透明面板1011上,当然,发光二极管灯带1012也可以通过其他方式固定在可调节透明面板1011上,只要能满足使发光二极管灯带1012在可调节透明面板1011上不发生脱落以及晃动现象即可。
其中,可以理解的,可调节透明面板1011的形状以及尺寸没有具体要求,只需要满足与第一背光组件101的形状以及尺寸吻合即可。
具体的,请参阅图7,图7为本申请实施例提供的第一背光组件的结构示意图,如图4所示,本申请实施例提供的第一背光组件第一背光组件101包括可调节透明面板1011以及位于可调节透明面板一端的发光二极管灯带1012,其中,可调节透明面板1011包括透明基极1013、铟锡氧化物电极1014、散射材料层1015以及框胶1016;透明基极1013包括第一透明基极10131以及第二透明基极10132,第一透明基极10131和第二透明基极10132相对设置;铟锡氧化物电极1014位于第一透明基极10131和第二透明基极10132之间,铟锡氧化物电极1014包括第一铟锡氧化物电极10141以及第二铟锡氧化物电极10142,第一铟锡氧化物电极10141和第二铟锡氧化物电极10142相对设置;散射材料层1015位于第一铟锡氧化物电极10141以及第二铟锡氧化物电极10142之间;框胶1016设置在散射材料层1015远离发光二极管灯带1012的一端以及散射材料层1015靠近发光二极管灯带1012的一端,且框胶1016位于第一铟锡氧化物电极10141以及第二铟锡氧化物电极10142之间。
其中,在一种实施方式中,本申请提供的可调节透明面板1011为散射型可调节透明面板。所谓的散射型可调节透明面板指的是,在可调节透明背光板1011呈背光态时,可调节透明面板1011对从发光二极管灯带1012的光起到散射作用;当然,从发光二极管灯带1012的光经过可调节透明面板1011的散射调整后,能形成均匀面光源。
其中,可以理解的,散射材料层1015由散射性材料构成,第一电压为能控制散射材料层1015中的散射性材料起到散射作用的电压,第二电压为能控制散射材料层1015中的散射性材料起到散射作用的电压;另外,通过在铟锡氧化物电极1014是否施加电压,就可以控制散射材料层1015中的散射性材料是否散射,因此一般情况下,第一电压为大于零伏的电压,第二电压为零伏的电压。
因此,当施加第一电压至铟锡氧化物电极1014;从而就可以使散射材料层1015中的散射性材料,对从发光二极管灯带1012射入可调节透明面板1011的光起到散射作用;从而改变从发光二极管灯带1012射出的光的传播途径,并使之形成均匀面光源。
当施加第二电压至铟锡氧化物电极1014;此时,散射材料层1015中的散射性材料没有得到激发,就不能起到改变射入可调节透明面板1011的光的传播路径的作用;接着还关闭了发光二极管灯带1012,此时可调节透明面板1011外的光可以透过可调节透明面板1011传播。
其中,可以理解的,在散射材料层1015远离发光二极管灯带1012的一端以及靠近发光二极管灯带1012的一端均设置框胶1016,主要是为了封闭散射材料层1015中的散射材料;防止散射材料在可调节透明面板1011移动的过程中从散射材料层1015中泄露,从而无法对从发光二极管灯带1012射入可调节透明面板1011的光起到散射作用的效果。
在本申请实施例提供的第一背光组件中,第一背光组件可以在透明态以及背光态切换的,在第一背光组件呈透明态时,此时液晶显示屏幕内外的光可透过第一背光组件传播;在第一背光组件呈背光态时,此时第一背光组件发出的光会形成均匀面光源,以作为背光源向液晶显示屏幕提供背光。因此采用可以在透明态以及背光态切换的第一背光组件,可以使正常显示和光学元件的使用可以在同一片液晶显示屏幕上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。
具体的,请参阅图8,图8为本申请实施例提供的液晶显示屏幕10的第一结构示意图,如图8所示,本申请实施例提供的液晶显示屏幕10包括背光模组10a以及液晶显示面板10b;其中,液晶显示面板10b包括相对设置的第一面10b1以及第二面10b2,背光模组10a设置在液晶显示面板10b的第二面10b2上。
其中,可以理解的,当背光模组10a呈背光态时,背光模组10 a发出的光的传播路径会发生改变,以形成均匀面光源,使背光模组10 a作为背光源为液晶显示面板10提供背光;当背光模组10 a呈透明态时,液晶显示屏幕10内外的光可透过液晶显示面板10b以及背光模组10 a传播。
因此,采用背光模组10 a这一结构,不需要在液晶显示面板10b上预留刘海或开口区域这种方式,就可以使液晶显示屏幕10内外的光可透过液晶显示面板10b以及背光模组10 a传播;从而可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本的前提下,解决现有设备中液晶显示屏幕10难以透光的技术问题。
其中,可以理解的,现有设备指的是采用液晶显示屏幕10作为显示的设备,比如手机,平板等智能设备。
具体的,请参阅图9,图9为本申请实施例提供的液晶显示屏幕的第二结构示意图,如图9所示,本申请实施例提供的液晶显示屏幕10包括背光模组10a以及液晶显示面板10b,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面10b1以及第二面10b2,第一背光组件101设置在液晶显示面板10b的第二面10b2上,第二背光组件102设置在液晶显示面板10b的第二面10b2上,第二背光组件102中部设置有一通孔102c;另外,第一背光组件101设置在第二背光组件102远离液晶显示面板10b的一侧,第一背光组件101覆盖通孔102c;且光学元件10c与通孔102c相对位置。
其中,可以理解的,由于第一背光组件101对于光的利用率不足,因此可以在光学元件10c与液晶显示面板10b之间增加一个第二背光组件102,使第二背光组件102也作为液晶显示面板10b的背光源,这样,液晶显示面板10b增加了一个新的背光源,就算第一背光组件101对于光的利用率不足,第二背光组件102加上第一背光组件101均作为液晶显示面板10b的背光源,也足够提供给液晶显示面板10b足够的背光。
其中,可以理解的,第一背光组件101设置在第二背光组件102远离液晶显示面板10b的一侧,因此,从第二背光组件102射出至液晶显示面板10b的光不会受到第一背光组件101的影响。
但是,液晶显示屏幕10外的光在传至液晶屏幕10内部以及液晶屏幕10内部的光在传至液晶显示屏幕10之外时,均会受到第二背光组件102的影响,因此,在第二背光组件102中部设置一通孔102c,因此第一背光组件101呈透明态时,液晶显示屏幕10外的光传至液晶屏幕10内部,以及液晶屏幕10内部的光传至液晶显示屏幕10之外,均不会受到影响。
因此,这样设置不仅解决了第一背光组件101对于光线的利用率不足,从而造成液晶显示屏幕10显示效果变差的技术问题,而且可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本的前提下,解决现有设备中液晶显示屏幕10难以透光的技术问题。
其中,在一种实施方式中,第二背光组件102包括遮光层以及设置在遮光层一侧的背光层,遮光层位于第二背光组件102远离液晶显示面板10b的一侧,背光层位于第二背光组件102靠近液晶显示面板10b的一侧,其中,背光层用于向液晶显示面板10b输出背光,遮光层用防止背光层用于向液晶显示面板10b输出背光时,向其他液晶显示面板10b接收不到背光的方向输出背光,从而可以增加液晶显示面板10b可以接收的背光量,提高第二背光组件102的背光利用率,进而提高液晶显示面板的显示效果。
其中,在一种实施方式中,第一背光组件101的一端高于第二背光组件102,此时,发光二极管灯带1012设置在这一端,其中,可以理解的,因为第一背光组件101的另一端与第二背光组件102的另一端平行,把发光二极管灯带1012设置在另一端就需要增加发光二极管灯带1012所处的空间,从而会增加成本,因此一般把发光二极管灯带1012设置在第一背光组件101与第二背光组件102不平行的一端。
具体的,请参阅图10,图10为本申请实施例提供的液晶显示屏幕的第三结构示意图,如图10所示,本申请实施例提供的液晶显示屏幕10包括背光模组10a以及液晶显示面板10b,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面1021以及第二面1022,第一背光组件101设置在液晶显示面板10b的第二面1022上,第二背光组件102设置在液晶显示面板10b的第二面1022上;第二背光组件102中部设置有一通孔102c;第一背光组件101设置在第二背光组件102靠近所液晶显示面板10b的一侧,第一背光组件101包括第一部分102a以及设置在第一部分102a两端的第二部分102b;其中,第一部分102a与通孔102c相对设置。
其中,可以理解的,第一背光组件101设置在第二背光组件102靠近液晶显示面板10b的一侧,第二背光组件102输出至液晶显示面板10b的光线都会经过第一背光组件101;而当第一背光组件101呈背光态并充当液晶显示面板10b的背光源时,会改变经过第一背光组件101的光线的传播路径;因此,如果不改变第一背光组件101,那么第二背光组件102作为液晶显示面板10b的背光源,输出至液晶显示面板10b的光线都会发生改变,那样,第二背光组件102就不能充当液晶显示面板10b的背光源。
因此,把第一背光组件101分为第一部分101a以及设置在第一部分101a两端的第二部分101b,其中,第一部分101a与通孔102c相对设置,第一部分101a呈透明态或背光态,第二部分101b呈透明态。
其中,可以理解的,第一部分101a可以在透明态或背光态切换;因此,当第一背光组件101的第一部分101a呈透明态时,液晶显示屏幕10内外的光可以透过液晶显示面板10b以及第一背光组件101传播,当第一背光组件101的第一部分101a呈背光态时,第一背光组件101可以充当液晶显示面板10b的背光源。
其中,可以理解的,第二部分101b呈透明态;因此,可调节透明背光板102的第二部分101b不会改变第二背光组件102输出至液晶显示面板10b的光线的传播路径,第二背光组件102输出至液晶显示面板10b的光线可以安全到达;因此,可以此时可以增加液晶显示面板10b接收到的光线,从而可以提升液晶显示面板10b的显示效果。
其中,在一种实施方式中,发光二极管灯带1012设置在第一背光组件101的第二部分101b较短的一端,其中,可以理解的,发光二极管灯带发出的光需要第一背光组件101的第一部分101a调整传播路径,而经过第一背光组件101的第二部分101b的部分越长,就会损失更多的光线,因此,为了提高发光二极管灯带1012发出的光的利用率,因此一般把发光二极管灯带1012设置在第一背光组件101的第二部分101b较短的一端。另外,发光二极管灯带1012投影所处的位置与第二背光组件102不重合,主要是为了防止发光二极管灯带1012影响到第二背光组件102传输至液晶显示面板10b的光线,从而进一步的提高光的利用率。
具体的,请参阅图11,图11为本申请实施例提供的液晶显示屏幕的第四结构示意图,如图11所示,本申请实施例提供的液晶显示屏幕10包括包括背光模组10a以及液晶显示面板10b,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面102a以及第二面102b,第一背光组件101设置在液晶显示面板10b的第二面102b上,第二背光组件102设置在液晶显示面板10b的第二面102b上;第二背光组件102的一端边缘处设置有一通孔102c,且第一背光组件101设置在通孔102c内,第一背光组件101与第二背光组件102平行设置。
其中,可以理解的,此时第一背光组件101与第二背光组件102平行设置,没有先后顺序,因此不存在第一背光组件101阻挡透过第二背光组件102的光,或者第二背光组件102阻挡透过第一背光组件101的光的现象,因此,液晶显示屏幕10外的光传至液晶显示屏幕10内部,以及液晶显示屏幕10内部的光传至液晶显示屏幕10之外时,均不会受到第二背光组件102的影响。
因此,通过把第一背光组件101在背光态以及透明态切换,就可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本的前提下,解决现有设备中液晶显示屏幕10难以透光的技术问题。
其中,在一种实施方式中,发光二极管灯带1012设置在第一背光组件101远离第二背光组件102的一端,且发光二极管灯带1012投影所处的位置与液晶显示面板10b不重合;其中,可以理解的,其一,发光二极管灯带1012投影所处的位置与液晶显示面板10b不重合,这主要是为了使液晶显示屏幕10内部射出液晶显示屏幕10外的光以及液晶显示屏幕10射向液晶显示屏幕10内部的光均不会被发光二极管灯带1012所阻挡,其二,发光二极管灯带1012设置在第一背光组件101远离第二背光组件102的一端,主要是为了增大第一背光组件101对于发光二极管灯带1012发出的光的利用率。
具体的,请参阅图12,图12为本申请实施例提供的液晶显示屏幕10的第五结构示意图,如图12所示,本申请实施例提供的液晶显示屏幕10包括背光模组10 a、液晶显示面板10b以及光学元件10c;其中,液晶显示面板10b包括相对设置的第一面10b1以及第二面10b2,背光模组10a设置在液晶显示面板10b的第二面10b2上,光学元件10c位于第一背光组件101远离液晶显示面板10b的一面上。
其中,可以理解的,当背光模组10a呈背光态时,背光模组10a发出的光的传播路径会发生改变,以形成均匀面光源,使背光模组10a作为背光源为液晶显示面板10提供背光;当背光模组10a呈透明态时,液晶显示屏幕10内外的光可透过液晶显示面板10b以及背光模组10a传播,以使光学元件10c正常工作。
因此,采用背光模组10a这一结构,不需要在液晶显示面板10b上预留刘海或开口区域,或者采用升降的方式弹出光学元件10c这两种方式,就可以使光学元件10c接收到液晶显示屏幕10外的光;从而可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本的前提下,解决现有液晶显示屏幕10难以透光的技术问题,满足现有设备中对于正面光学元件的需求;另外,采用背光模组10a使正常显示和光学元件10c的使用可以在同一片液晶显示屏幕10上实现,这为真正的无机械结构的液晶显示全面屏的实现提供了可能。
其中,在一种实施方式中,光学元件10c包括摄像头、光学指纹识别器、光线传感器以及距离传感器中的一种或多种。
具体的,请参阅图13,图13为本申请实施例提供的液晶显示屏幕的第六结构示意图,如图13所示,本申请实施例提供的液晶显示屏幕10包括背光模组10a、液晶显示面板10b以及光学元件10c,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面10b1以及第二面10b2,第一背光组件101设置在液晶显示面板10b的第二面10b2上,光学元件10c设置在第一背光组件101远离液晶显示面板10b的一面上,第二背光组件102设置在液晶显示面板10b的第二面10b2上,且第二背光组件102也位于液晶显示面板10b与光学元件10c之间,第二背光组件102中部设置有一通孔102c;另外,第一背光组件101设置在第二背光组件102远离液晶显示面板10b的一侧,第一背光组件101第一背光组件101覆盖通孔102c;且光学元件10c与通孔102c相对位置。
其中,可以理解的,由于第一背光组件101对于光的利用率不足,因此可以在光学元件10c与液晶显示面板10b之间增加一个第二背光组件102,使第二背光组件102第也作为液晶显示面板10b的背光源,这样,液晶显示面板10b增加了一个新的背光源,就算第一背光组件101对于光的利用率不足,第二背光组件102加上第一背光组件101均作为液晶显示面板10b的背光源,也足够提供给液晶显示面板10b足够的背光。
其中,可以理解的,第一背光组件101设置在第二背光组件102远离液晶显示面板10b的一侧,因此,从第二背光组件102射出至液晶显示面板10b的光不会受到第一背光组件101的影响。
但是,液晶显示屏幕10外的光在传至光学元件10c以及光学元件10c的光在传至液晶显示屏幕10之外时,均会受到第二背光组件102的影响,因此,在第第二背光组件102中部设置一通孔102c,且把光学元件10c与通孔102c相对设置,因此第一背光组件101呈透明态时,液晶显示屏幕10外的光传至可光学元件10c,以及光学元件10c的光传至液晶显示屏幕10之外,均不会受到影响。
因此,这样设置不仅解决了第一背光组件101对于光线的利用率不足,从而造成液晶显示屏幕10显示效果变差的技术问题,而且还不影响到液晶显示屏幕10正常显示和光学元件10c的使用可以在同一片液晶显示屏幕10上实现的效果。
其中,在一种实施方式中,第二背光组件102包括遮光层以及设置在遮光层一侧的背光层,遮光层位于第二背光组件102远离液晶显示面板10b的一侧,背光层位于第二背光组件102靠近液晶显示面板10b的一侧,其中,背光层用于向液晶显示面板10b输出背光,遮光层用防止背光层用于向液晶显示面板10b输出背光时,向其他液晶显示面板10b接收不到背光的方向输出背光,从而可以增加液晶显示面板10b可以接收的背光量,提高第二背光组件102的背光利用率,进而提高液晶显示面板的显示效果。
其中,在一种实施方式中,第一背光组件101的一端高于第二背光组件102,此时,发光二极管灯带1012设置在这一端,其中,可以理解的,因为第一背光组件101的另一端与第二背光组件102的另一端平行,把发光二极管灯带1012设置在另一端就需要增加发光二极管灯带1012所处的空间,从而会增加成本,因此一般把发光二极管灯带1012设置在第一背光组件101与第二背光组件102不平行的一端。
具体的,请参阅图14,图14为本申请实施例提供的液晶显示屏幕的第七结构示意图,如图14所示,本申请实施例提供的液晶显示屏幕10包括背光模组10a、液晶显示面板10b以及光学元件10c,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面1021以及第二面1022,第一背光组件101设置在液晶显示面板10b的第二面1022上,光学元件10c设置在第一背光组件101远离液晶显示面板10b的一面上,第二背光组件102设置在液晶显示面板10b的第二面1022上,且第二背光组件102也位于液晶显示面板101与光学元件10c之间;第二背光组件102中部设置有一通孔102c,光学元件10c设置在通孔102c内;第一背光组件101设置在第二背光组件102靠近所液晶显示面板10b的一侧,第一背光组件101包括第一部分102a以及设置在第一部分102a两端的第二部分102b;其中,第一部分102a与通孔102c相对设置。
其中,可以理解的,第一背光组件101设置在第二背光组件102靠近液晶显示面板10b的一侧,第二背光组件102输出至液晶显示面板10b的光线都会经过第一背光组件101;而当第一背光组件101呈背光态并充当液晶显示面板10b的背光源时,会改变经过第一背光组件101的光线的传播路径;因此,如果不改变第一背光组件101,那么第二背光组件102作为液晶显示面板10b的背光源,输出至液晶显示面板10b的光线都会发生改变,那样,第二背光组件102就不能充当液晶显示面板10b的背光源。
因此,把第一背光组件101分为第一部分101a以及设置在第一部分101a两端的第二部分101b,其中,第一部分101a与通孔102c相对设置,第一部分101a呈透明态或背光态,第二部分101b呈透明态。
其中,可以理解的,第一部分101a可以在透明态或背光态切换,而第一部分101a与光学元件10c相对设置;因此,当第一背光组件101的第一部分101a呈透明态时,液晶显示屏幕10内外的光可以透过液晶显示面板10b以及第一背光组件101传播,以使光学元件10c正常工作,当第一背光组件101的第一部分101a呈背光态时,第一背光组件101可以充当液晶显示面板10b的背光源。
其中,可以理解的,第二部分101b呈透明态;因此,可调节透明背光板102的第二部分101b不会改变第二背光组件102输出至液晶显示面板10b的光线的传播路径,第二背光组件102输出至液晶显示面板10b的光线可以安全到达;因此,可以此时可以增加液晶显示面板10b接收到的光线,从而可以提升液晶显示面板10b的显示效果。
其中,在一种实施方式中,发光二极管灯带1012设置在第一背光组件101的第二部分101 b较短的一端,其中,可以理解的,发光二极管灯带发出的光需要第一背光组件101的第一部分101a调整传播路径,而经过第一背光组件101的第二部分101b的部分越长,就会损失更多的光线,因此,为了提高发光二极管灯带1012发出的光的利用率,因此一般把发光二极管灯带1012设置在第一背光组件101的第二部分101b较短的一端。另外,发光二极管灯带1012投影所处的位置与第二背光组件102不重合,主要是为了防止发光二极管灯带1012影响到第二背光组件102传输至液晶显示面板10b的光线,从而进一步的提高光的利用率。
具体的,请参阅图15,图15为本申请实施例提供的液晶显示屏幕的第八结构示意图,如图15所示,本申请实施例提供的液晶显示屏幕10包括包括背光模组10a、液晶显示面板10b以及光学元件10c,其中,背光模组10a包括第一背光组件101以及第二背光组件102;
其中,液晶显示面板10b包括相对设置的第一面102a以及第二面102b,第一背光组件101设置在液晶显示面板10b的第二面102b上,光学元件10c设置在第一背光组件101远离液晶显示面板10b的一面上,第二背光组件102设置在液晶显示面板10b的第二面102b上,且第二背光组件102也位于液晶显示面板10b与光学元件10c之间;第二背光组件102的一端边缘处设置有一通孔102c,且第一背光组件101设置在通孔102c内,第一背光组件101与第二背光组件102平行设置;。
其中,可以理解的,此时第一背光组件101与第二背光组件102平行设置,没有先后顺序,因此不存在第一背光组件101阻挡透过第二背光组件102的光,或者第二背光组件102阻挡透过第一背光组件101的光的现象。
而且,光学元件10c设置在第一背光组件101远离液晶显示面板10b的一面上,因此,液晶显示屏幕10外的光传至光学元件10c,以及光学元件10c的光传至液晶显示屏幕10之外,也不会收到第二背光组件102的影响。
因此,通过把第一背光组件101在背光态以及透明态切换,就可以使正常显示和光学元件10c的使用可以在同一片液晶显示屏幕10上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。
其中,在一种实施方式中,发光二极管灯带1012设置在第一背光组件101远离第二背光组件102的一端,且发光二极管灯带1012投影所处的位置与液晶显示面板10b不重合;其中,可以理解的,其一,发光二极管灯带1012投影所处的位置与液晶显示面板10b不重合,这主要是为了使光学元件10c射出液晶显示屏幕10外的光以及液晶显示屏幕10射向光学元件10c的光均不会被发光二极管灯带1012所阻挡,其二,发光二极管灯带1012设置在第一背光组件101远离第二背光组件102的一端,主要是为了增大第一背光组件101对于发光二极管灯带1012发出的光的利用率。
在本申请实施例提供的液晶显示屏幕中,通过设置可以在透明态以及背光态切换的背光模组,在使用光学元件时,使背光模组呈透明态,此时,液晶显示屏幕内外的光可透过液晶显示面板以及背光模组传播,从而不影响光学元件的正常使用,而在液晶显示面板需要背光时,使背光模组呈背光态,此时背光模组作为背光源向液晶显示面板提供背光。因此,采用可以在透明态以及背光态切换的背光模组,可以使正常显示和光学元件的使用可以在同一片液晶显示屏幕上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。而且背光模组不需要在液晶显示屏幕上预留刘海或开口区域,或者采用升降的方式弹出光学元件,因此也不会不破坏全面屏的完整性以及增大手机损坏可能性和维修成本,因此,本申请实施例提供的液晶显示屏幕可以在不破坏全面屏的完整性以及增大手机损坏可能性和维修成本解决现有液晶显示屏幕难以透光的技术问题。
具体的,请参阅图16,图16为本申请是实施例提供的液晶显示屏幕的使用方法的流程示意图,如图16所示,本申请是实施例提供的液晶显示屏幕的使用方法包括:步骤201、当光学元件接收光线时,液晶显示屏幕外的光依次穿过液晶显示面板以及背光模组至光学元件,以使光学元件接收到液晶显示屏幕外的光;202、当光学元件不接收光线时,背光模组发出的光的传播路径会发生改变,以形成均匀面光源,使背光模组作为背光源为液晶显示面板提供背光。
其中,可以理解的,当光学元件接收光线时,此时背光模组呈透明态时,背光模组不发光,且液晶显示屏幕外的光可透过液晶显示面板以及背光模组传播至光学元件,以使光学元件接收到液晶显示屏幕外的光;
当光学元件不接收光线时,此时背光模组呈背光态,背光模组发出的光的传播路径会发生改变,以形成均匀面光源,使背光模组作为背光源为液晶显示面板提供背光,以使液晶显示面板显示图像。
因此,采用本申请实施例所提供的液晶显示屏幕的使用方法,通过一种可在背光态以及透明态切换的背光模组,可以使正常显示和光学元件的使用可以在同一片液晶显示屏幕上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。
具体的,请参阅图17,图18,图17为本申请实施例提供的液晶显示屏幕应用摄像头的第一结构示意图,图18为本申请实施例提供的液晶显示屏幕应用摄像头的第二结构示意图,如图17,图18所示,在本申请实施例提供的液晶显示屏幕应用摄像头的结构示意图中,液晶显示屏幕30包括第一背光组件第一背光组件301、液晶显示面板302、摄像头303以及第二背光组件第二背光组件304;其中,液晶显示面板302包括相对设置的第一面3021以及第二面3022,第一背光组件301设置在液晶显示面板302的第二面3022上,摄像头303设置在第一背光组件301远离液晶显示面板302的一面上,第二背光组件304设置在液晶显示面板302的第二面3022上,且第二背光组件304也位于液晶显示面板301与摄像头303之间,第二背光组件304中部设置有一通孔3041;另外,第一背光组件301设置在第二背光组件304远离液晶显示面板301的一侧,第一背光组件301覆盖通孔3041;且摄像头303与通孔3041相对位置;其中,
第一背光组件301包括可调节透明面板3011以及位于可调节透明面板3011一侧的发光二极管灯带3012;其中,可调节透明面板3011包括透明基极3013、铟锡氧化物电极3014、散射材料层3015以及框胶3016;透明基极3013包括第一透明基极30131以及第二透明基极30132,第一透明基极30131和第二透明基极30132相对设置;铟锡氧化物电极3014位于第一透明基极30131和第二透明基极30132之间,铟锡氧化物电极3014包括第一铟锡氧化物电极30141以及第二铟锡氧化物电极30142,第一铟锡氧化物电极30141和第二铟锡氧化物电极30142相对设置;散射材料层3015位于第一铟锡氧化物电极30141以及第二铟锡氧化物电极30142之间;框胶3016设置在散射材料层3015远离发光二极管灯带3012的一端以及散射材料层3015靠近发光二极管灯带3012的一端,且框胶3016位于第一铟锡氧化物电极30141以及第二铟锡氧化物电极30142之间。
其中,图17中所示的第一背光组件301呈背光态,此时图17中所示的第一光线传播路径30121为发光二极管灯带3012传输至可调节透明面板3011内部的光线传播路径,第二光线传播路径30122为经过可调节透明面板3011调整后输出至可调节透明面板3011外界的光线传播路径。
其中,可以理解的,发光二极管灯带3012传输至可调节透明面板3011的光线经过可调节透明面板3011调整后,从可调节透明面板3011靠近液晶显示面板302一侧以及可调节透明面板3011远离液晶显示面板302一侧均射出,因此,虽然会损失一部分光线,但还有一部分从发光二极管灯带3012射出的光线经过可调节透明面板3011调整后输出至液晶显示面板302,因此,第一背光组件301呈背光态时,第一背光组件301可以作为液晶显示面板302的背光源,为液晶显示面板302提供光线。
其中,图18中所示的第一背光组件301呈透明态,此时,位于液晶显示面板302远离摄像头303一侧的图像3031为液晶显示屏幕30外的实物,位于摄像头303远离液晶显示面板301一侧的图像3032为摄像头303形成的液晶显示屏幕30外实物的照片。
其中,可以理解的,此时,第一背光组件301呈透明态,可调节透明面板3011不会改变从液晶显示屏幕30外界传输至摄像头303的光的传播路径,也不会改变从摄像头303传输至液晶显示屏幕30外界的光的传播路径,因此,外界的实物可以清晰的在摄像头303上成像。
因此,采用可以在透明态以及背光态切换的背光模组,可以使正常显示和摄像头的使用可以在同一片液晶显示屏幕上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。
具体的,请参阅图19,图20,图19为本申请实施例提供的液晶显示屏幕应用光学指纹识别器的第一结构示意图,图20为本申请实施例提供的液晶显示屏幕应用光学指纹识别器的第二结构示意图,如图19,图20所示,在本申请实施例提供的液晶显示屏幕应用光学指纹识别器的结构示意图中,液晶显示屏幕40包括第一背光组件401、液晶显示面板402、光学指纹识别器403以及第二背光组件404;其中,液晶显示面板402包括相对设置的第一面4021以及第二面4022,第一背光组件401设置在液晶显示面板402的第二面4022上,光学指纹识别器403设置在第一背光组件401远离液晶显示面板402的一面上,第二背光组件404设置在液晶显示面板402的第二面4022上,且第二背光组件404也位于液晶显示面板401与光学指纹识别器403之间,第二背光组件404中部设置有一通孔4041;另外,第一背光组件401设置在第二背光组件404远离液晶显示面板401的一侧,第一背光组件401覆盖通孔4041;且光学指纹识别器403与通孔4041相对位置;其中,

其中,可以理解的,发光二极管灯带4012传输至可调节透明面板4011的光线经过可调节透明面板4011调整后,从可调节透明面板4011靠近液晶显示面板402一侧以及可调节透明面板4012远离液晶显示面板402一侧均射出,因此,虽然会损失一部分光线,但还有一部分从发光二极管灯带4012射出的光线经过可调节透明面板4011调整后输出至液晶显示面板402,因此,第一背光组件401呈背光态时,第一背光组件401可以作为液晶显示面板402的背光源,为液晶显示面板402提供光线。
其中,图20中所示的第一背光组件401呈透明态,此时,位于液晶显示面板402远离光学指纹识别器403一侧的图像4031为待识别的指纹,位于光学指纹识别器403远离液晶显示面板402一侧的图像4032为光学指纹识别器403形成的待识别指纹图像。
其中,在一种实施方式中,光学指纹识别器403包括短焦摄像头以及发光二极管灯,其中,发光二极管等位于光学指纹识别器403靠近液晶显示面板402的一侧。
其中,可以理解的,当使用光学指纹识别器403时,第一背光组件401呈透明态,因此,无法为液晶显示面板402提供光线,此时就需要发光二极管灯来照亮液晶显示面板402上指纹的图像4031,从而可以使短焦摄像头可以通过拍摄成像,从而得到待识别指纹的图像4032。
其中,可以理解的,此时,第一背光组件401呈透明态,可调节透明面板4011不会改变从液晶显示屏幕40外界传输至光学指纹识别器403的光的传播路径,也不会改变从光学指纹识别器403传输至液晶显示屏幕40外界的光的传播路径,因此,外界待识别指纹的具体特征可以清晰的在光学指纹识别器403上呈现。
因此,采用可以在背光态以及透明态切换的背光模组,可以使正常显示和光学指纹识别器的使用可以在同一片液晶显示屏幕上实现,为真正的无机械结构的液晶显示全面屏的实现提供可能。

其中,图21中所示为背光模组呈透明态时的手机液晶显示屏幕,此时,位于摄像头开口区503以及指纹识别区502的背光模组呈透明状态,此时摄像头5031以及光学指纹识别器5021可以正常接收到从手机液晶显示屏幕50外射入的光线,也可以传输光线至手机液晶显示屏幕50外,此时,摄像头5031以及光学指纹识别器5021可以正常工作;同时位于常规显示区501的背光模组依旧呈背光状态,因此手机液晶显示屏幕50的常规显示区501依旧正常显示画面。
