Description

一种LCD显示屏结构
技术领域
本发明涉及显示技术领域，具体涉及了一种LCD显示屏结构。
背景技术
在现有技术中，液晶显示器结构从上至下通常为偏光片、彩膜基板、液晶层、TFT玻璃基板、下偏光片和背光模组叠构而成一个显示屏。随着时代的发展，技术水平的不断提升，显示器的分辨率与尺寸在不断地变大，同时，具有窄边框、全面屏的显示器已成为市场上的主流。为了提升屏占比，各厂商也都在致力于缩小显示器的边框实现全面屏。为了标识各自的品牌，通常在全面屏的显示器上方贴合一片玻璃盖板，在将品牌标志印刷于盖板中来达成。
发明内容
针对现有技术的不足，本发明提供一种无需使用玻璃盖板和贴合工艺等的材料和组装，节省材料与提升组装效率和良率的LCD显示屏结构。
本发明的一种LCD显示屏结构，其包括依次向下层叠设置的上偏光片、TFT玻璃基板、彩膜基板、下偏光片和背光模组；所述TFT玻璃基板一侧设有FPC；所述背光模组包括背框和设在背框内的光源、导光板以及光学膜层；所述光源设在背框一侧；所述导光板设在背框另一侧，其包括入光面和出光面，所述导光板的入光面对应光源的出光面设置；所述光学膜层设置在导光板的出光面上；所述TFT玻璃基板设有FPC一侧的下边框区域上丝印或蚀刻有品牌标志，所述背框对应品牌标志处镂空形成出光口。
一种LCD显示屏结构，其包括依次向下层叠设置的上偏光片、TFT玻璃基板、彩膜基板、下偏光片和背光模组；所述TFT玻璃基板一侧设有FPC；所述背光模组包括背框和设在背框内的光源、导光板以及光学膜层；所述光源设在背框一侧；所述导光板设在背框另一侧，其包括入光面和出光面，所述导光板的入光面对应光源的出光面设置；所述光学膜层设置在导光板的出光面上；所述背框对应TFT玻璃基板设有FPC一侧的下边框区域镂空形成出光口，所述出光口内设有导光条，所述导光条的顶部或TFT玻璃基板的下边框区域上丝印或蚀刻有品牌标志。
进一步，所述上偏光片和TFT玻璃基板之间设有1/4λ玻片，或所述TFT玻璃基板中的TFT元器件和布线由黑色金属材料成型。
进一步，所述背框由顶板、底板以及四个侧壁形成的容纳腔，所述出光口设置在所述顶板靠近所述背框一侧的侧壁。
进一步，所述导光条包括顶部、支撑部以及限位部，所述顶部平行地设在顶板上方，顶部一端遮盖出光口，另一端延伸到顶板上方；所述支撑部一端垂直连接在顶部下，另一端伸入背框中与底板连接；所述限位部连接在支撑部背离出光口一侧，且平行地设在顶板下方。
进一步，所述TFT玻璃基板上的FPC沿着所述背框一侧的侧壁向下弯折，固定在背框底板的底面。
与现有技术相比，本发明的有益效果如下：
1、采用在TFT玻璃基板的下边框区域上丝印或蚀刻有品牌标志，在利用背光模组中的光源来高亮品牌标志，在点亮显示器的同时品牌标志同时高亮，增加品牌辨识度，使显示屏再不使用玻璃盖板的情况下实现全面屏，并节省盖板材料和贴合光学胶，提升组装效率和良率；
2、在对应TFT玻璃基板的下边框区域的背框镂空出光口，在出光口处增设导光条，进一步提高品牌标志的亮度，进一步增加品牌辨识度；
3、采用1/4λ玻片设在上偏光片和TFT玻璃基板之间，或所述TFT玻璃基板中的TFT元器件和布线由黑色金属材料成型，防止外部环境入射光从偏光片进入后会与TFT玻璃基板的电路金属层反射形成相同偏振光射出造成视觉炫光，进一步提升画面的对比度；
4、采用FPC代替PCB+FPC电路，直接将FPC弯折并固定于背光后，方便安装。
