Description

车载倍电流液晶模组
技术领域
本发明涉及液晶模组技术领域，具体是一种车载倍电流液晶模组。
背景技术
液晶显示器 (Liquid Crystal Display，LCD) 由于体积小、厚度薄、重量轻及低功耗而广泛应用在个人电脑、移动电话、电视、车载系统及监视器等电子产品，液晶模组是液晶显示器的重要组成部分，液晶模组的辉度一般在250cd/㎡左右，高亮液晶模组可做到300 cd/㎡~350 cd/㎡左右，但对车载系统来说，此亮度的液晶模组无法满足强光下车载液晶模组辉度的要求。
发明内容
本发明所要解决的技术问题是：提供一种能够提高辉度，有效改善散热问题的车载倍电流液晶模组。
本发明所采用的技术方案是：提供一种车载倍电流液晶模组，包括自上而下依次层叠设置的上铁框、上偏光片、LCD屏、下偏光片、上增光片、下增光片、下扩散膜、胶框、多组灯条和灯条PCB组件、导光板、反射膜和下铁框，所述LCD屏上设置软性线路板，每组灯条的电流为60mA，PCB组件的线路宽度为1.2～1.5mm。
采用上述结构后，本发明车载倍电流液晶模组通过改变灯条内部芯片参数，将驱动电流由原来的每组20mA提升到每组60 mA，在原有基础上整整提升三倍，液晶模组整体辉度可提升到500cd/㎡以上，从而满足强光下高辉度液晶模组需求，同时将PCB组件的线路宽度由0.3mm拓展为1.2～1.5mm，增加电流流通线路横截面积，电路横截面积越大，阻抗越小，电流通过时所产生的热量也热小；本发明还改变个元件的位置，灯条所发出的热量能够通过下铁框散热，下铁框导热性能更好，可快速有效的将灯条所产生的热量传递出去，且无支架变形引起爆灯，光束不良现象，从而有效的改善散热现象，对整个液晶模组散热性能方面也有很大提升。
附图说明
图1为本发明的结构示意图。
图中，1、上铁框，2、上偏光片，3、LCD屏，4、下偏光片，5、软性线路板，6、上增光片，7、下增光片，8、下扩散膜，9、胶框，10、灯条和灯条PCB组件，11、导光板，12、反射膜,13、下铁框。
具体实施方式
以下结合附图和实施例对本发明做详细的说明。
如图1所示，本发明车载倍电流液晶模组，包括自上而下依次层叠设置的上铁框1、上偏光片2、LCD屏3、下偏光片4、上增光片6、下增光片7、下扩散膜8、胶框9、多组灯条和灯条PCB组件10、导光板11、反射膜12和下铁框13，LCD屏3上设置软性线路板5（FPC），每组灯条的电流为60mA，PCB组件的线路宽度为1.2～1.5mm。
以上对本发明的实施例进行了详细说明，但所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明范围所作的均等变化与改进等，均应仍归属于本专利涵盖范围之内。
