Description

节能型触控液晶显示装置 技术领域
本发明是有关于一种液晶显示器，特别是有关于一种节能型触控液晶显示装置。
 背景技术
现今市场上的液晶显示器的供电均是由外部输入。由交流市电经过变压、转换成低压直流电之后再输入至液晶显示装置直接使用，或者储蓄于电池上再使用。因此，液晶显示器的能耗全部来自外部电源。
随着全球暖化效应的加剧，电子产品的节能功能显得更为重要，对产品节能设计的要求也更加紧迫。液晶显示装置也考虑以各种有利环保的方式获取能源，进行驱动。然而目前市场上的液晶显示装置并无法满足此要求。
故，有必要提供一种节能型触控液晶显示装置，以解决现有技术所存在的问题。
 技术问题
本发明提供一种节能型触控液晶显示装置，以解决现有液晶显示器无法节约能源消耗的问题。
 技术解决方案
有鉴于现有技术的缺点，本发明的主要目的在于提供一种节能型触控液晶显示装置，将使用者操作过程中的机械能转换电能后进行再利用，以节省电力消耗。
为达成本发明的前述目的，本发明提供一种节能型触控液晶显示装置，包含：
一液晶面板，内装有触控组件而在其显示区上提供一触控面；
一压电薄膜，感应所述触控面所受到的按压力而产生电能；以及
一电池模组，连接所述压电薄膜及液晶面板而储存所述压电薄膜产生的电能，并提供所述液晶面板。
在本发明的一实施例中，所述液晶面板包含一上基板及一下基板；所述压电薄膜是夹设于所述上基板与下基板之间。
在本发明的一实施例中，所述上基板为彩色滤光片基板，所述下基板为薄膜晶体管阵列基板。
在本发明的一实施例中，进一步包含一背光模组，所述液晶面板是以其底面装设于所述背光模组上；所述压电薄膜是设于所述液晶面板的底面。
在本发明的一实施例中，进一步包含一保护层，所述保护层是设于所述液晶面板的顶面；所述压电薄膜是夹设于所述保护层与所述液晶面板之间。
 有益效果
本发明主要是利用压电材料在使用者进行触控操作时将机械能转化成电能，而储存于电池之中，并经过电路传输，将电能传输至电子组件上使用，以节省产品从外部电源消耗的电能，达到节能的目的。
 附图说明
图1是本发明节能型触控液晶显示装置第一较佳实施例的平面示意图。
图2是本发明节能型触控液晶显示装置第一较佳实施例的剖面示意图。
图3是本发明节能型触控液晶显示装置第二较佳实施例的剖面示意图。
图4是本发明节能型触控液晶显示装置第三较佳实施例的剖面示意图。
 本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下。再者，本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参考图1所示，图1为节能型触控液晶显示装置一较佳实施例的平面示意图。本发明的节能型触控液晶显示装置包含有一液晶面板10、一压电薄膜20及一电池模组30。
所述液晶面板10的内部装设有触控组件，而在其一显示区上提供一触控面100。
所述压电薄膜20用以感应所述液晶面板10的触控面100所受到使用者的按压力。由于压电薄膜20的电偶极矩的电偶极矩会随应力压迫而变短，压电薄膜20此时为扺抗此种趋势，将产生电能以保持原状态。
所述电池模组30是连接所述压电薄膜20而储存所述压电薄膜20产生的电能。本实施例中，所述压电薄膜20是通过一柔性印刷电路板300连接至一电路板301上的电池模组30。
当使用者在进行触控操作时，以其手指或者触控笔按压液晶面板10的触控面100时，压电薄膜20感受到压力变化而产生电能，经由所述柔性印刷电路板300传输到所述电路板301上的电池模组30进行储存。触控液晶显示装置中的电子元件工作时，所述电池模组30即可供电给所述电子元件，从而达到节省外部电源的使用。
请参考图2所示，图2是本发明节能型触控液晶显示装置第一较佳实施例的剖面示意图。所述节能型触控液晶显示装置进一步包含一背光模组40及一保护层50。所述液晶面板10是以其底面装设于所述背光模组40上；所述保护层50是设于所述液晶面板10的顶面。再者，所述液晶面板10包含一上基板11及一下基板12。所述上基板11优选为彩色滤光片基板，所述下基板12优选为薄膜晶体管阵列基板。
所述压电薄膜20可视需求设置在触控液晶显示装置的不同部位。在图2的实施例中，所述压电薄膜20是夹设于所述保护层50与所述液晶面板10之间。
请参考图3所示，图3是本发明节能型触控液晶显示装置第二较佳实施例的剖面示意图。有别于图2的实施例，在图3的实施例中，所述压电薄膜20是夹设于所述上基板11与下基板12之间。
请参考图4所示，图4是本发明节能型触控液晶显示装置第三较佳实施例的剖面示意图。有别于图2跟图3的实施例，在图4的实施例中，所述压电薄膜20是设于所述液晶面板10的底面，而位于液晶面板10与背光模组40之间。
由上述说明可知，相较于现有触控液晶显示装置仅能依赖外部电源运转工作，本发明利用压电材料在使用者进行触控操作时将机械能转化成电能，而储存于电池之中。电池的电能可经过电路传输而传输给触控液晶显示装置的电子组件使用，以降低触控液晶显示装置使用外部电源提供的电能，达到节能的目的。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
