Description

液晶显示器及其制备方法 技术领域

 背景技术
在图像领域中，液晶显示器的响应时间，是液晶显示器各像素点对输入信号反应的速度，即像素由暗转亮或由亮转暗所需要的时间。响应的原理，是在液晶分子内施加电压，利用液晶分子的扭转与恢复控制光的通断。反应时间越短，则使用者在看动态画面时越不会有尾影拖曳的感觉。
液晶分子在环境低于0℃时，会变得粘稠，呈现出可肉眼辨识的差异。温度更低时，液晶分子甚至会结晶，从而导致液晶显示器在低温启动工作时，显示画面变色、两地低、出现拖尾严重等现象。在极低的温度下（一25C以下），液晶分子甚至无法正常工作。

 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面对实施例中所需要使用的附图作简单的介绍。下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获取其他的附图。
图1为本发明实施例一中液晶显示器的模块示意图；
图2A为本发明实施例一中液晶分子在断电情况下的液晶分子分布示意图；
图2B为本发明实施例一中液晶分子在通电情况下的液晶分子分布示意图；
图3为本发明实施例二中液晶显示器的模块示意图；

 本发明的最佳实施方式
请参照附图中的图式，其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本发明具体实施例，其不应被视为限制本发明未在此详述的其它具体实施例。
实施例一
请参阅图1，所示为本发明实施例中液晶显示器的模块示意图。
所述液晶显示器主要包括：彩膜基板10、阵列基板20、取向膜30、液晶层40、加热层50、框胶60、以及背光源70。
具体而言，所述彩膜基板10，用于提供彩色滤光区。
所述阵列基板20，设置有薄膜晶体管（未标示）。
所述取向膜30，分别铺设于所述彩膜基板10与所述阵列基板20上。
所述液晶层40，包括多层液晶分子。
所述液晶层中的所述液晶分子以对称的曲列结构排列来实现自我补偿视角，中间层的液晶分子始终垂直于所述彩膜基板，上下各层以对称的曲列结构排列，且越远离中心预倾角越大。
如图2A与图2B所示，分别为液晶分子在断电、通电情况下的液晶分子分布示意图。在图2A的断电情况下，液晶分子41以一种对称的曲列结构排列，中间层的液晶分子41始终垂直于屏幕，上下的液晶分子41则对称的呈现出距离中央越远，预倾角越大。在图2B的通电情况下，液晶分子41开始发生偏转，最终出现对称的叠加。由于液晶层40始终都是对称的，这样由下面液晶分子41双折射所导致的相位差刚好可以利用上面部分的液晶分子41自行抵消，获得宽视角。
所述加热层50，铺设于所述取向膜30与所述彩膜基板10之间，用于为所述液晶层40加热。
可以理解的是，所述加热层50的材料可以选择为碳纳米管薄膜，导电性好、热导率高等优点。且满足透明的显示需求。
还可以在所述加热层50的一边设置一输入电极51，在所述输入电极51的对边设置输出电极52，用于传输加热的电流。其中，所述加热的电流既可以来自于专门的供电电路，也可以来来自于原有的电路元件，如阵列基板20上的薄膜晶体管。其实现是通过由框胶60进行固定的至少两个导电金球61进行的。
具体而言，第一导电金球61，连接于所述薄膜晶体管与所述加热层的输入端51；第二导电金球62，连接于所述薄膜晶体管与所述加热层的输出端52；框胶60，用于将所述彩膜基板10与所述阵列基板20进行对盒。
背光源70，位于阵列基板20的一侧，用于为液晶显示器提供显示用的光源。
本实施例所提供的液晶显示器，通过在彩膜基板上设置加热层，避免了在低温情况下液晶分子由于粘度过大导致的不易扭转的情形，从而提高了液晶显示器在低温情形下的响应时间。且仅设置一层加热层，其工艺简单、材料成本与铺设的制备成本都较为低廉。
实施例二
请参阅图3，所示为本发明液晶显示器的又一模块示意图。
与实施例一的差别在于，除了在彩膜基板10上增加了加热层50外，还增加了对温度的感测功能，用于在适当的情况下开启所示加热功能。
具体而言，包括：控制开关83、温度传感器81、以及比较电路82。
所述控制开关83，用于控制所述加热层电流的通断。所述控制开关可以连接于所述加热层50、导电金球61、或TFT（未标示）中的某一段。
所述温度传感器81，用于接收当前温度。
所述比较电路82，用于判断所述当前温度与预设温度的高低，并当所述当前温度低于所述预设温度时，通过所述控制开关83的关闭以导通所述加热层的电流。
可以理解的是，所述控制开关83进一步还可以包括调节电路84，用于根据比较电路82，连接不同的电阻，以在导通的情况下输出不同的电流值，进而对所述加热层50的输出温度进行控制，以提高最适宜的温度。
本实施例所提供的液晶显示器，通过在彩膜基板上设置加热层，避免了在低温情况下液晶分子由于粘度过大导致的不易扭转的情形，从而提高了液晶显示器在低温情形下的响应时间。且仅设置一层加热层，其工艺简单、材料成本与铺设的制备成本都较为低廉。
实施例三
请参阅图4，所示为本发明实施例中一种液晶显示器的制备方法，用于制备上述液晶显示器。具体而言，包括如下步骤：
在步骤S401中，制备彩膜基板，用于提供彩色滤光区。
在步骤S402中，在所述彩膜基板上铺设加热层。
可以理解的是，在铺设完成后，在所述加热层的一边设置输入电极；在所述输入电极的对边设置输出电极。
在步骤S403中，在所述加热层上铺设取向膜。
可以理解的是，在步骤S401~403之后，由所述彩膜基板、所述加热层、以及所述取向膜形成第一基板。
在步骤S404中，制备阵列基板，所述阵列基板上设置有薄膜晶体管。
在步骤S405中，在所述阵列基板上铺设取向膜。
可以理解的是，在步骤S404~405之后，由所述阵列基板和所述取向膜形成第二基板。可以理解的是，上述形成第一基板与形成第二基板的步骤可同时进行。
