Description
技术领域
本发明涉及液晶模块技术领域，具体属于一种带嵌框液晶模块。
背景技术
液晶模块是数字标牌的内胆，有数字标牌的所有功能部件，具备数字标牌的所有功能，具备完整紧凑的结构，但没有原数字标牌的外箱，这种产品主要用于安装环境比较高的场所。普通液晶模块中的印刷电路板和背光板安装时，通常是在印刷电路板上打孔或开槽，采用固定螺栓固定安装，此种连接方式不仅浪费印刷电路板上面的空间，在多个液晶模块拼接使用时，间隙较大；同时印刷电路板和背光板的侧边容易出现漏光问题，严重影响液晶模块的整体使用性能。针对上述问题，本发明提供了一种带嵌框液晶模块。
发明内容
本发明目的是提供一种带嵌框液晶模块，可解决上述背景技术中提到的问题。
本发明所采用的技术方案如下：
一种带嵌框液晶模块，其特征是包括液晶显示屏、背光板、印刷电路板和框，所述液晶显示屏安装在背光板上面，印刷电路板安装在背光板下面，液晶显示屏、背光板和印刷电路板整体安装在框内，所述框的四角为耳型，框的中间为中空区域，框的耳型四角有窄边连接，所述窄边为U形，内侧有凹槽、凸起和长条形通孔，所述背光板为LED背光板，背光板与印刷电路板连接区域的侧面有感温条，所述感温条的边缘部位有导电双面胶，所述感温条的中间有感温变色区间，所述感温变色区间的颜色有灰色、绿色、蓝色、橙色和红色，所述感温变色区间安装位置对准框窄边上的长条形通孔，所述印刷电路板上面有沟槽，沟槽底宽上口窄，沟槽内侧有向外通孔，沟槽内有凝固的环氧树脂胶，凝固后的环氧树脂胶上表面光滑，在凝固后的环氧树脂胶上面加工有孔，孔内安装有导电条，导电条和环氧树脂胶的上表面涂敷有胶黏剂，背光板安装在胶黏剂上。
所述框有铝合金制成，框窄边内侧的凸起嵌装在印刷电路板沟槽内侧的向外通孔内，框窄边内侧的凸起与凝固后的环氧树脂胶上面孔内的导电条不接触。
所述框窄边外侧有挂卡。
与已有技术相比，本发明的有益效果如下：
本发明通过对液晶显示屏、背光板、印刷电路板和框的整体优选设计组合，制造出一种带嵌框液晶模块，所述框的四角为耳型，框的中间为中空区域，框的耳型四角有窄边连接，所述窄边为U形，内侧有凹槽、凸起和长条形通孔，印刷电路板上面有沟槽，沟槽底宽上口窄，沟槽内侧有向外通孔，沟槽内有凝固的环氧树脂胶，凝固后的环氧树脂胶上表面光滑，在凝固后的环氧树脂胶上面加工有孔，孔内安装有导电条，导电条和环氧树脂胶的上表面涂敷有胶黏剂，背光板安装在胶黏剂上，解决了普通液晶模块中的印刷电路板和背光板安装时，通常是在印刷电路板上打孔或开槽，采用固定螺栓固定安装，此种连接方式浪费印刷电路板上面空间的问题；所述背光板为LED背光板，背光板与印刷电路板连接区域的侧面有感温条，所述感温条的边缘部位有导电双面胶，解决了印刷电路板和背光板的侧边容易出现漏光，严重影响液晶模块整体使用性能的问题；所述框窄边外侧有挂卡，当多块液晶模块拼接时，框窄边外侧的挂卡整体卡装在框窄边内侧，解决了普通液晶模块在进行多个拼接使用时，间隙较大的问题。此外，所述背光板为LED背光板，背光板与印刷电路板连接区域的侧面有感温条，所述感温条的边缘部位有导电双面胶，所述感温条的中间有感温变色区间，所述感温变色区间的颜色有灰色、绿色、蓝色、橙色和红色，所述感温变色区间安装位置对准框窄边上的长条形通孔，可以直接观察到背光板和印刷电路板在使用过程中，温度的变化，提示人员及时维护，防止因温度高，影响液晶模块的使用性能。本发明取消了背光板与印刷电路板侧边通过金属螺栓连接，解决了液晶显示屏、背光板和印刷电路板侧边漏光的问题，拼装间隙小，整体拼装方便，适合批量化推广使用。
