具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
附图中各部件的形状和大小不反映真实比例,目的只是示意性说明本发明内容。
本发明实施例提供的一种液晶显示器,如图1a和图1b所示,包括背光源01,位于背光源01出光侧的下基板02,与下基板02相对设置的上基板03,位于上基板03与下基板02之间的液晶层04;还包括:
分别位于液晶层04两侧的第一透明电极06和第二透明电极,以及用于向第一透明电极06和第二透明电极施加电压的控制单元(图中未示出);其中,

控制单元用于,在显示时根据图像数据对各子电极070和第一透明电极06施加电压,使液晶层04中与各电极单元07对应区域的液晶分子发生偏转形成微棱镜结构,并通过控制各电极单元07中各子电极070上的电压的大小控制微棱镜结构,以控制背光源01的光经微棱镜结构折射后出射光线在预设视角范围内的能量分布比例。
本发明实施例提供的上述液晶显示器件,在显示时,通过控制单元根据图像数据对各子电极和第一透明电极施加电压产生电场,使液晶层中与各电极单元对应区域的液晶分子发生偏转形成微棱镜结构,并通过控制各电极单元中各子电极上的电压的大小控制微棱镜结构,以控制背光源的光经微棱镜结构折射后出射光线在预设视角范围内的能量分布比例,从而实现通过控制微棱镜结构实现进入到预设视角范围内的光亮度,进而实现灰阶显示。
需要说明是,在本发明实施例提供的上述液晶显示器中,出射光线在预设视角范围内的能量分布比例是指背光源中的光经一个微棱镜结构折射后的出射光线中射到预设视角范围内的出射光线的能量占该微棱镜结构折射后的所有出射光线能量的比例。
在具体实施时,在本发明实施例提供的上述液晶显示器中,如图1a所示,第一透明电极06位于上基板03面向液晶层04一侧,第二透明电极(包括图中各电极单元07)位于下基板02面向液晶层04一侧;
或者,如图1b所示,第二透明电极(包括图中各电极单元07)位于上基板03面向液晶层04一侧,第一透明电极06位于上基板03面向液晶层04一侧,在此不作限定。
可选地,所述第一透明电极06和第二透明电极位于所述上基板03与所述下基板02之间。利用上述布置,能够更加精确地控制液晶层04中的液晶分子。
下面结合具体实施例,对本发明的原理进行详细说明。需要说明的是,本实施例中是为了更好的解释本发明,但不限制本发明。
可选地,在本发明实施例提供的上述液晶显示器中,微棱镜结构为三角形棱镜结构和/或四边形棱镜结构。
具体地,分别以位于目标人眼左侧、右侧、和正对侧区域中的微棱镜结构为例,说明通过控制微棱镜结构实现控制微棱镜结构的出射光线在预设视角范围内的能量分布比例,从而实现灰阶显示的原理。
具体地,如图2a至图2d所示,当目标人眼位于微棱镜结构10的右侧时,微棱镜结构10向右折射的光进入目标人眼。如图2a所示,当微棱镜结构10为直角三角形棱镜时,且直角三角形棱镜的斜边在远离目标人眼一侧时,微棱镜结构10折射出的光全部射向目标人眼方向;即,进入目标人眼的出射光线的能量分布比例为100%,因此可以实现高灰阶显示。如图2b所示,当微棱镜结构10为等腰三角形棱镜时,微棱镜结构10折射出的光一半射向目标人眼方向;即,进入目标人眼的出射光线的能量分布比例为50%,因此可以实现中灰阶显示。如图2c所示,当微棱镜结构10为普通三角形棱镜时,且普通三角形棱镜的最短边在远离目标人眼一侧时,微棱镜结构10折射出的光小部分射向目标人眼方向;假设进入目标人眼的出射光线的能量分布比例为20%,因此可以实现中低灰阶显示;如图2d所示,当微棱镜结构10为直角三角形棱镜时,且直角三角形棱镜的斜边在靠近目标人眼一侧时,没有光线射向目标人眼方向,因此可以实现低灰阶显示。
具体地,如图3a至图3d所示,当目标人眼位于微棱镜结构10的左侧时,微棱镜结构10向左折射的光进入目标人眼。如图3a所示, 当微棱镜结构10为直角三角形棱镜时,且直角三角形棱镜的斜边在远离目标人眼一侧时,微棱镜结构10折射出的光全部射向目标人眼方向;即,进入目标人眼的出射光线的能量分布比例为100%,因此可以实现高灰阶显示。如图3b所示,当微棱镜结构10为等腰三角形棱镜时,微棱镜结构10折射出的光一半射向目标人眼方向;即,进入目标人眼的出射光线的能量分布比例为50%,因此可以实现中灰阶显示。如图3c所示,当微棱镜结构10为普通三角形棱镜时,且普通三角形棱镜的最短边在远离目标人眼一侧时,微棱镜结构10折射出的光小部分射向目标人眼方向;假设进入目标人眼的出射光线的能量分布比例为20%,因此可以实现中低灰阶显示。如图3d所示,当微棱镜结构10为直角三角形棱镜时,且直角三角形棱镜的斜边在靠近目标人眼一侧时,没有光线射向目标人眼方向,因此可以实现低灰阶显示。
具体地,如图4a至图4g所示,当目标人眼位于微棱镜结构10的正对侧时,微棱镜结构10向正前方折射的光进入目标人眼。如图4a所示,当微棱镜结构10为矩形棱镜时,微棱镜结构10折射出的光全部射向目标人眼方向;即,进入目标人眼的出射光线的能量分布比例为100%,因此可以实现高灰阶显示。如图4b至4e所示,当微棱镜结构10为梯形棱镜时,且梯形棱镜比较短的底边在靠近目标人眼一侧时,微棱镜结构10折射出的光部分射向目标人眼方向,因此可以实现中灰阶显示。具体地,射向目标人眼的比例可以通过调节梯形棱镜两底边的相对长度实现,假设图4b和图4c进入目标人眼的出射光线的能量分布比例为60%,图4d和图4e进入目标人眼的出射光线的能量分布比例为30%。如图4f和图4g所示,当微棱镜结构10为三角形棱镜时,微棱镜结构10没有沿正前方折射的光出射;即,没有光线射向目标人眼方向,因此可以实现低灰阶显示。
上面仅是通过通过举例具体的微棱镜结构,说明如何通过控制微棱镜结构在预设视角范围内的出射光线的能量分布比例实现灰阶显示的原理。具体的微棱镜结构还可以是其它能使实现本发明实施例方案的结构。微棱镜结构通过根据图像数据控制第一透明电极和各子电极的大小进行控制,在此不作限定。另外,图2a至图4g中的眼睛仅是为了演示目标人眼所在的方向,在具体实施时眼睛的大小可以对应很多个微棱镜结构。
进一步,在具体实施时,在本发明实施例提供的上述液晶显示器中,微棱镜结构在沿液晶显示器的盒厚方向的等效光程厚度越厚,施加在微棱镜结构对应的液晶层两侧的透明电极上的电压差越小。以微棱镜结构为直角三角形棱镜为例,如图5所示,假设一个电极单元07中包括有四个平行设置的子电极070,且子电极070为直线状,则在图5中,由左至右,四个子电极070上的电压分别为V1、V2、V3和V4,且V1>V2>V3>V4,微棱镜结构10的等效光程厚度越来越厚。
可选地,在具体实施时,在本发明实施例提供的上述液晶显示器中,如图6a和图6b所示,子电极070由至少一条直线状电极0701组成。
或者,可选地,在具体实施时,在本发明实施例提供的上述液晶显示器中,如图6c和图6d所示,子电极070由多个点状电极0702组成。在具体实施时点状可以是具有规则形状的点,例如圆点、方点等,当然也可以为不规则形状的点,在此不作限定。
本发明实施例提供的上述液晶显示器,是利用微棱镜结构在预设视角范围内的出射光线的能量分布比例来控制灰阶的。背光源的光一般为圆偏光,因此可以通过设置在下基板上的第一偏光片05将背光源的光转换为线偏光,并通过控制微棱镜结构精确控制预设视角范围内的出射光线的能量分布比例。
进一步地,在具体实施时,要通过控制微棱镜结构控制其在预设视角范围内的出射光线的能量分布比例,需要保证背光源射向液晶棱镜显示面板的光的入射方向是一致的。因此可选地,在本发明实施例提供的上述液晶显示器中,背光源发出的光为准直线光或平行光。
进一步地,为了实现彩色显示,在本发明实施例提供的上述液晶显示器中,如图7a和图7b所示,还包括位于液晶层04背离下基板02一侧的光色转换层08。光色转换层08用于将透过液晶层04的、且与各微棱镜结构对应区域的光转换为至少一种颜色的光,且背光源01的光透过光色转换层08后转换为至少三种颜色的光。
需要说明的是,这里一种颜射的光相当于现有液晶显示器中的一个子像素,因此在本发明实施例提供的上述液晶显示器中,一个微棱镜结构对应至少一个子像素,而液晶显示器包括至少三种颜色的子像素,例如三原色的红色子像素、蓝色子像素和绿色子像素,在此不作 限定。
可选地,在本发明实施例提供的上述液晶显示器中,一个微棱镜结构对应一个子像素,即光色转换层在与各微棱镜结构对应的区域仅转换成一种颜色的光。
在具体实施时,在本发明实施例提供的上述液晶显示器中,如图7a所示,光色转换层08可以内嵌于上基板03与下基板02之间,当然光色转换层08也可以设置于上基板03背向液晶层04一侧,在此不作限定。
进一步地,在本发明实施例提供的上述液晶显示器中,光色转换层08为分光膜或彩色滤光膜,包括至少一种颜色的滤光片;每个滤光片可以对应例如一个微棱镜结构,在此不作限定。
可选地,在本发明实施例提供的上述液晶显示器中,如图8a和图8b所示,还包括位于上基板03背离液晶层04一侧的第二偏光片09,且第二偏光片09的透光轴方向与第二偏光片09的透光轴方向平行,这样通过第二偏光片09进一步对液晶显示器出射光进行线偏光作用,可以有效提高显示效果。
进一步地,在本发明实施例提供的上述液晶显示器中,可以将预设视角范围固定在某一范围内,这样控制单元根据图像数据控制各微棱镜结构在该预设视角范围内的出射光线的能量分布比例。然而,当目标人眼超出该预设视角范围时,就不能正常进行观看了。因此可选地,本发明实施例提供的上述液晶显示器中,还包括人眼追逐单元;
人眼追踪单元用于通过追踪目标人眼确定预设视角范围,并将确定的预设视角范围发送给控制单元;
控制单元根据预设视角范围调节施加在各电极单元中的各子电极的电压。
基于同一发明构思,本发明实施例还提供了一种电子设备,包括本发明实施例提供的上述液晶显示器,该电子设备可以为:照明设备、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有照明或显示功能的产品或部件。该电子设备的实施可以参见上述液晶显示器的实施例,重复之处不再赘述。
本发明实施例提供的上述液晶显示器和电子设备,在显示时,通过控制单元根据图像数据对各子电极和第一透明电极施加电压产生电 场,使液晶层中与各电极单元对应区域的液晶分子发生偏转形成微棱镜结构,并通过控制各电极单元中各子电极上的电压的大小控制微棱镜结构,以控制背光源的光经微棱镜结构折射后出射光线在预设视角范围内的能量分布比例,从而实现通过控制微棱镜结构实现进入到预设视角范围内的光亮度,进而实现灰阶显示。
显然,本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
