图2是根据另一示例性实施例示出的一种液晶显示组件的结构示意图。该液晶显示组件可以是诸如手机、平板电脑、笔记本电脑、智能电视等电子设备的LCD(Liquid Crystal Display,液晶显示器)面板。
如图2所示,该液晶显示组件包括:上基板210、与上基板210相对平行设置的下基板220、封入于上基板210和下基板220之间的液晶层230、贴附于上基板210的与液晶层230非相邻一面的上偏光片240、以及贴附于下基板220的与液晶层230非相邻一面的下偏光片250。
可选地,如图2所示,上基板210包括:上玻璃基板211和CF212。其中,上玻璃基板211的下表面与液晶层230相邻,CF212贴附于上玻璃基板211的上表面。CF212使得LCD面板可呈现彩色画面,CF212上排布有若干个R、G、B三种颜色所对应的不同像素色块。如图3所示,其示例性地示出了像素色块在CF上几种不同的排布方式。在第一种可能的排布方式中,如图示中的CF31,R、G、B三种颜色所对应的不同像素色块呈条状排列。在第二种可能的排布方式中,如图示中的CF32,R、G、B三种颜色所对应的不同像素色块呈三角形排列。在第三种可能的排布方式中,如图示中的CF33,R、G、B三种颜色所对应的不同像素色块呈正方形排列。在第四种可能的排布方式中,如图示中的CF34,R、G、B三种颜色所对应的不同像素色块呈马赛克排列(或称为对角形排列)。当然,图3示出的几种排布方式仅是示例性和解释性的,本实施例并不限定其它可能的排布方式。

可选的,如图2所示,下基板220包括:下玻璃基板221和TFT阵列222。其中,下玻璃基板221的上表面与液晶层230相邻;下玻璃基板221的上表面上设置有TFT阵列222和分布在TFT阵列222之间的第二黑色矩阵223。
如图5所示,其示出了一种下玻璃基板221的侧视图。第二黑色矩阵223用于防止背景光泄漏,提高LCD面板的显示对比度,防止混色和增加颜色的纯度。
如图2所示,该液晶显示组件还包括:至少一个接近光传感器260和控制芯片270,接近光传感器260包括至少一个发射端261和至少一个接收端262。
其中,接近光传感器260的发射端261用于发射光信号,当存在物体接近时,光信号会被物体遮挡从而形成反射信号,接收端262用于接收该反射信号。电子设备通过检测接近光传感器260中的接收端262是否接收到反射信号,即可检测出是否存在物体接近。
各个接近光传感器260设置于上偏光片240和下偏光片250之间。且每个接近光传感器260分别与控制芯片270电性相连。接近光传感器260用于将光信号转换为电信号后提供给控制芯片270。
下面对接近光传感器260的排布方式进行介绍。
例如:各个接近光传感器260可设置于下玻璃基板221的上表面,此时,每个接近光传感器260的发射端261和接收端262都设置于下玻璃基板221的上表面;再例如,各个接近光传感器260还可设置于CF212上,此时,每个接近光传感器260的发射端261和接收端262都设置于CF212上,等等。
可选地,当接近光传感器260的数量为多个时,例如当接近光传感器260为n(n≥2)个时,该n个接近光传感器260均匀且分散地排布。各个接近光传感器260的至少一个发射端261设置于第一黑色矩阵212b和第二黑色矩阵中223的至少一个上,且各个接近光传感器260的至少一个接收端262设置于第一黑色矩阵212b和第二黑色矩阵223中的至少一个上。
例如,在图5中,空白圆圈表示接近光传感器260中的发射端261,阴影圆 圈表示接近光传感器260中的接收端262,各个接近光传感器260的至少一个发射端261和至少一个接收端262全部都均匀且分散地排布于下玻璃基板221的第二黑色矩阵223。
再例如:将各个接近光传感器260的至少一个发射端261全部都分散地排布于第一黑色矩阵212b上,且至少一个接收端262全部都分散地排布于第二黑色矩阵223上;或者,将各个接近光传感器260的至少一个发射端261全部都分散地排布于第二黑色矩阵223上,且至少一个接收端262全部都分散地排布于第一黑色矩阵212b上。
再例如:将部分接近光传感器260的至少一个发射端261和至少一个接收端262全部都分散地排布于第一黑色矩阵212b上,另一部分接近光传感器260的至少一个发射端261和至少一个接收端262全部都分散地排布于第二黑色矩阵223上。
再例如:将部分接近光传感器260的至少一个发射端261全部都分散地排布于第一黑色矩阵212b上,且至少一个接收端262全部都分散地排布于第二黑色矩阵223上,另一部分接近光传感器260的至少一个发射端261全部都分散地排布于第二黑色矩阵223上,且至少一个接收端262全部都分散地排布于第一黑色矩阵212b上。
本实施例不对接近光传感器260的至少一个发射端261和至少一个接收端262的排布方式做限定。
通过设置多个接近光传感器260,并将该多个接近光传感器260均匀且分散地排布,不再局限于利用接近光传感器260在某一个孔中检测是否存在物体接近,而是在整个电子设备的液晶显示面板范围内检测是否存在物体接近,解决了相关技术中将接近光传感器260设置在小孔中,导致接近光传感器260的接收端262接收到的,来自于发射端261发射出的光信号的反射信号的数量减少的问题,并且解决了将接近光传感器260设置在小孔中时,需要在电子设备上打孔,影响美观的问题。
此外,通过将接近光传感器260的发送端261和接收端262设置在第二黑色矩阵223或第一黑色矩阵212b上,可以确保接近光传感器260的设置不会干扰到LCD面板的透光率,进而确保LCD面板的显示效果不受影响。
可选地,结合参考图4,接近光传感器260与控制芯片270通过导线280相 连,各个导线280也设置于CF212的第一黑色矩阵212b或者设置于下玻璃基板221的第二黑色矩阵223上。通过将导线280也设置在第一黑色矩阵212b或者第二黑色矩阵223上,可以确保导线280的设置不会干扰到LCD面板的透光率,进而确保LCD面板的显示效果不受影响。可选地,导线280也可以由透明材料制成。
如图2所示,该液晶显示组件还可包括:至少一个背光源290。该至少一个背光源290与控制芯片270电性相连。背光源290设置于下偏光片250的背面。背光源290用于在LCD面板背后提供光源。背光源290的类型包括但不限于EL(Electro Luminescent,电致发光)、CCFL(Cold Cathode Fluorescent Lamp,冷阴极荧光灯管)、LED(Light Emitting Diode,发光二极管)等类型中的任意一种。
另外,控制芯片270可以是MCU(Microcontroller Unit,微控制单元),MCU也称为单片微型计算机或者单片机,是一种芯片级的计算机。在一种可能的实现方式中,以MCU根据接近光传感器计算出的手指与液晶显示屏之间的距离,动态控制背光亮度为例,各个接近光传感器260的接收端261采集发射端260发射的光信号的反射信号,MCU从各个接近光传感器260获取反射信号,对获取的反射信号进行计算处理,并根据计算处理结果确定在距离液晶显示面板预设距离内是否有物体接近,然后根据确定结果,控制背光源290发光或者不发光。例如,当MCU计算结果为在距离液晶显示面板1cm内,存在物体接近时,控制背光源290不发光;当MCU计算结果为在距离液晶显示面板1cm内,不存在物体接近时,控制背光源290发光。
可选的,也可以不在液晶显示屏中设置预设距离,即,MCU只要接收到接近光传感器260的接收端262的反射信号,就认为存在物体接近。
另外,液晶显示组件所对应的显示区域可以是一个完整的显示区域,该显示区域对应设置有至少一个背光源290。各个背光源290用于控制整个显示区域的背光亮度。
或者,可选地,如图6所示,液晶显示组件所对应的显示区域61被划分为m(m≥2)个显示区块(如图示的第一显示区块62、第二显示区块63、第三显示区块64以及第四显示区块65),每一个显示区块对应设置有至少一个背光源290,且每一个显示区块对应设置有至少一个接近光传感器260。对于每一个显 示区块,其所对应的若干个背光源290用于单独控制该显示区块的背光亮度。例如,假设第一显示区块62对应设置有第一背光源和第一接近光传感器,第二显示区块63对应设置有第二背光源和第二接近光传感器,则第一背光源用于根据第一接近光传感器的接收端采集的反射信号,单独控制第一显示区块62的背光亮度,第二背光源用于根据第二接近光传感器的接收端采集的反射信号,单独控制第二显示区块63的背光亮度。通过将LCD面板所对应的显示区域划分为多个显示区块,并利用不同的背光源对该多个显示区块的背光亮度进行分区控制,提高了背光控制的灵活性。
综上所述,本公开提供的液晶显示组件,通过将接近光传感器设置于上偏光片和下偏光片之间,使得接近光传感器在检测是否存在物体接近时,不再局限于在某个小孔中来检测是否存在物体接近,解决了相关技术通过开孔设置接近光传感器,而导致的电子设备外表不美观的问题,达到了无需单独开孔,可以节约电子设备的前面板面积,提高电子设备的整体设计美感的效果。
另外,通过将接近光传感器的至少一个发射端设置于第一黑色矩阵和第二黑色矩阵中的至少一个上,且接近光传感器的至少一个接收端设置于第一黑色矩阵和第二黑色矩阵中的至少一个上,确保接近光传感器的设置不会干扰到LCD面板的透光率,进而确保LCD面板的显示效果不受影响,并且使得接近光传感器的接收端在接收发射端发射的光信号的反射信号时,不再受发射角度和接收角度的局限,解决了接近光传感器的发射端发射光信号和接收端反射信号时,由于角度限制,使得接近光传感器无法在整个电子设备的液晶显示面板内,检测接近的物体的问题,达到了增加了接收端接收的反射信号的数量,使得接近光传感器可以在整个电子设备的液晶显示面板内检测接近的物体的效果。
根据本公开的另一实施例,还提供了一种电子设备。例如,该电子设备可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。该电子设备包括如上述图1或图2所示实施例提供的液晶显示组件。
本领域技术人员在考虑说明书及实践这里公开的发明后,将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化, 这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的,本公开的真正范围和精神由下面的权利要求指出。
应当理解的是,本公开并不局限于上面已经描述并在附图中示出的精确结构,并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
