为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图作 筒单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例， 而非对本发明的限制。
图 1为本发明实施例的液晶盒结构图；
附图标记说明：
1、 上偏光片； 2、 上基板； 3、 彩膜； 4、 公共电极； 5、 液晶； 6、 像素 电极； 7、 下基板； 8、 下偏光片； 9、 红外层。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
术语 "液晶盒" 除包括所属领域内具有一般技能的人士所理解的 "阵列 基板"、 "彩膜基板" 和 "填充在阵列基板和彩膜基板之间的液晶" 夕卜， 还包 括覆于彩膜基板的与液晶相反侧的 "上偏光片" 和覆于阵列基板的与液晶相 反侧的 "下偏光片"。 根据本发明一实施例， 提供一种液晶盒， 该液晶盒中设置有包含红外材 料的组件。 例如， 该包含红外材料的组件可以是由红外材料制成的红外层。 以下参照图 1进行详细说明。
图 1是根据本发明一示例的液晶盒， 包括上偏光片 1、上基板 2、彩膜 3、 公共电极 4、 液晶 5、 像素电极 6、 下基板 7、 下偏光片 8和红外层 9。 通常， 上基板 2与彩膜 3构成彩膜基板， 下基板 7与像素电极 6构成阵列基板。 所 述上、下基板 2、 7可以采用诸如玻璃的透明材料制成以利于光的透过。由此， 该液晶盒包括相对设置的彩膜基板和阵列基板。 在本示例中， 所述红外层 9 设置于所述彩膜基板上， 即上基板 2和上偏光片 1之间。 可以理解的是， 所 述红外层 9还可设置于阵列基板上， 或还可设置在彩膜基板和阵列基板二者 上。
当然， 实际应用中的液晶盒中各组件关系不一定如图 1所示， 本发明只 是以图 1为例进行描述。
红外层 9包含能够通过热交换产生红外光线的材料（筒称红外材料），该 红外材料可以在被光照射时通过吸收能量产生红外光线， 产生的红外光线的 波长通常为 0.77 μ ιη~1ιηιη。并且， 红外光线的强弱可以通过红外材料有效成 分的粒径、 表面形态和含量来控制。
上 述 的 该 红 外 材 料 可 以 是 ： 生 物 炭 、 电 气 石 ( [Na,K,Ca][Mg,F,Mn,Li,Al]3[Al,Cr,Fe,V]6[B03]3[Si6018][OH,F]4 )、 远红外陶 瓷、 玉石粉、 氧化铝、 氧化铜、 氧化银以及碳化硅中的一种或两种以上的混 合物。 红外材料的粒径可在纳米级至微米级。
如图 1所示， 红外层 9设置于上偏光片 1与上基板 2之间， 这种设置方 式可以基于如下方法实现：
清洗上基板 2;
在上基板 2的背面 （即如图所示的上基板 2面向上偏振片的表面 )涂布 红外层 9, 并固化红外层 9; 以及
在上基板 2的正面形成彩膜 3。
在一个例子中， 在上基板 2的正面制取彩膜 3包括：
在上基板 2的正面上形成黑矩阵；
形成红绿蓝（R\G\B )子像素； 以及 形成隔垫物。
在上述方法中， 还可以在涂布完红外层 9之后， 在红外层 9上涂布保护 层， 该保护层的功能是防止红外层 9在彩膜 3的制取过程受到损伤。 在制取 完彩膜 3后， 可以将红外层 9上的保护层剥离。
可选地， 除了图 1所示的将红外层 9设置于上偏光片 1与上基板 2之间 这种方式以外， 还可以将红外层 9设置于上基板 2与彩膜 3之间， 这种设置 方式可以基于如下方法实现：
清洗上基板 2;
在上基板 2的正面 （即上基板 2相对于上偏光片 1的另一面）涂布红外 层 9, 并固化红外层 9;
在红外层 9上制取彩膜 3。
在一个例子中， 在红外层 9上制取彩膜 3包括：
在红外层 9上形成黑矩阵；
形成 R\G\B子像素； 以及
形成隔垫物。
无论是将红外层 9设置于上偏光片 1与上基板 2之间， 还是将红外层 9 设置于上基板 2与彩膜 3之间，均可以认为是将红外层 9设置于彩膜基板上。 这时， 可以将红外层 9涂布在彩膜基板整个表面上， 也可以将红外层 9涂布 在部分表面上， 例如涂布在彩膜基板的黑矩阵所在的区域或涂布在彩膜基板 的1 \0\6子像素所在区域， 以在相应区域内发出红外光线或者是增强相应区 域的红外光线强度。
需要说明的是， 在本发明其他示例中， 也可以将红外层 9设置于液晶盒 中的其它位置， 如： 将红外层 9设置于彩膜 3与公共电极 4之间， 或者将红 外层 9设置于像素电极 6与下基板 7之间， 或者将红外层 9设置于下基板 7 与下偏光片 8之间等。
根据本发明的另一个实施例， 还提供一种液晶盒， 无论该液晶盒是否设 置有红外层 9, 均可在生产液晶盒的各组件时， 将红外层 9所包含的红外材 料掺杂在至少一个组件中， 如： 将红外层 9所包含的红外材料掺杂在以下组 件中至少之一中： 上偏光片 1、 上基板 2、 彩膜 3、 公共电极 4、 像素电极 6、 下基板 7、 下偏光片 8。 再有， 上述的红外层 9中的红外材料可以是经过表面改性处理的， 这样 该红外材料就能够实现与液晶盒相应结构相容以及最佳的性能匹配， 避免因 红外材料的引入而影响液晶显示器件的性能。 所述表面改性处理的目的在于 改变所述红外材料的表面形态、晶界结构，从而使其与液晶盒相应结构相容， 不影响显示器件的性能； 同时表面改性处理的目的还在于通过改变所述红外 材料的表面形态、 晶界结构， 从而改变红外材料的活性， 提高热交换能力， 以高的比辐射率放射特定波长的远红外线。
根据本发明的再一实施例， 提供一种对红外材料的表面改性的方法， 包 括以下步骤：
1 )对红外材料进行纳米化处理， 获得红外材料的纳米粒子； 以及
2 )改变进行纳米化处理后的纳米粒子的表面特性，以使其与液晶盒相应 结构层相容、 并与其性能匹配， 并在被光照射时发射出红外光线。
该步骤 1 ) 的主要目的是对红外材料进行纳米化处理， 以获得红外材料 的纳米粒子。 该研磨、 分散方法可用制备纳米材料的常用方法进行， 例如可 采用常规的研磨装置（例如球磨机、砂磨机等 )和分散剂在有机溶剂中进行。 该纳米分散溶液中的红外材料的重量百分比可为 10~15%。 在一个示例中， 所述步骤 1 )包括： 将红外材料研磨、 分散， 获得平均粒径为 lnm~200nm的 红外材料纳米分散溶液。
步骤 2 )的目的是改变步骤 1 )中分散后的纳米粒子的表面特性，使其与 液晶盒相应结构相容， 不影响显示器件的性能； 同时该步骤的目的还在于通 过将经过纳米化处理的红外材料进行进一步的表面改性， 从而改变红外材料 的活性， 提高热交换能力， 以高的比辐射率放射特定波长的远红外线。 在一 个示例中， 所述步骤 2 ) 包括：
将所述红外材料的^：溶液与含有甲基丙烯酸甲酯、 苯乙烯、 马来酰亚 胺的有机溶液混合， 然后将偶氮类引发剂溶液加入上述混合物中； 以及
待反应结束后， 加入冷却用有机溶剂进行冷却并搅拌， 直至反应产物冷 却后过滤、 干燥， 得到表面改性的红外材料。
在另一个示例中， 所述步骤 2 ) 包括：
将诸如偶氮二异戊腈、 偶氮二异丁腈、 偶氮二异己腈、 偶氮二异庚腈等 的偶氮类引发剂溶解在有机溶剂中待用； 将红外材料的纳米分散溶 四口瓶内，同时对其进行搅拌、震荡（频 率高于 50Hz )或摇动等处理；
将单体甲基丙烯酸甲酯、 苯乙烯和马来酰亚胺（按摩尔比例 1:1~2:1~2 ) 溶于有机溶剂 （单体和有机溶剂按体积比例 1:1~1:3),并将所得到溶液加入上 述四口瓶内， 其中红外材料占四口瓶内混合溶液总重量的 8~25% , 优选 10-20%, 更优选 12~17%；
所述改变进行纳米化处理后纳米粒子表面特性的环境条件是在 35° C-60 。( 温度下、 同时在氮气气氛下，使偶氮类引发剂溶液以基于以上单体的总重 量的 1~5%的引发剂的量逐滴加入上述四口瓶内， 在搅拌、 震荡或摇动等处 理下进行反应 30分钟 ~90分钟；
反应结束后加入 5~10°C的冷却用有机溶剂进行冷却处理， 同时搅拌直至 反应产物冷却至室温；
过滤三次后， 用上述用于溶解单体的有机溶剂清洗滤出的固体， 在 70~100°C下干燥 5分钟 ~20分钟， 得到表面改性的红外材料。
以上方法中所用有机溶剂可为脂肪醇、 乙二醇醚、 乙酸乙酯、 甲乙酮、 甲基异丁基酮、 单甲基醚乙二醇酯、 γ -丁内酯、 丙酸 -3-乙醚乙酯、 丁基卡必 醇、 丁基卡必醇醋酸酯、 丙二醇单甲基醚、 丙二醇单甲基醚醋酸酯、 环己烷、 二甲苯、 异丙醇中的一种或多种。
以上方法中所用分散剂为常用分散剂， 例如 ΒΥΚ 410、 ΒΥΚ 110、 ΒΥΚ 163、 ΒΥΚ 161、 ΒΥΚ 2000等。分散剂占纳米^:溶液的重量百分比为 5% ~ 15%, 优选为 7 ~ 12%。
根据本发明的又一实施例， 还提供一种液晶盒， 该液晶盒中设置有包含 红外材料的组件， 所述红外材料根据以上表面改性方法得到。
根据本发明的再一实施例， 还提供一种液晶显示装置， 包括背光源， 还 包括以上任一种液晶盒。 该液晶显示装置可以为诸如便携式电脑、 手机、 电 子书等便携式电子设备的显示器。
由于本发明上述实施例的液晶盒中设置有包含红外材料的组件， 因此当 为液晶盒提供光照的背光源或者是外界光（如太阳光等）照射液晶盒时， 液 晶盒可以发出较强渗透力和辐射力的红外光线。 红外光线被人体吸收后， 可 使人体内水分子产生共振， 使水分子活化， 增强水分子间的结合力， 从而活 化蛋白质等生物大分子， 使生物细胞处于高振动能级。 由于生物细胞产生共 振效应， 可将远红外热能传递到人体皮下较深的部分， 因此深层温度上升， 产生的热量由内向外散发， 使毛细血管扩张， 促进血液循环， 强化各组织之 间的新陈代谢， 增加组织的再生能力， 提高机体的免疫能力， 有利于健康， 也能尽量减轻电磁辐射对身体健康的影响。 同理， 在包含本发明的所述液晶 盒的液晶显示装置中， 背光源或者外界光（如太阳光等）照射液晶盒时， 液 晶盒可以向液晶显示装置外部发出红外光线， 因此所述液晶显示装置有利于 健康， 也能尽量减轻电磁辐射对身体健康的影响。 再有， 经过表面改性的红 外材料能够实现与液晶盒结构的相容以及性能的最佳匹配， 在不影响液晶显 示器件性能的情况下提高红外材料与背光及外界光的热交换能力， 经过表面 改性的红外材料以高的比辐射率放射特定波长的远红外线。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
