Description

液晶显示器及其电路板固定方法 技术领域
本发明涉及液晶显示器技术领域，特别是涉及一种液晶显示器及其电路板固定方法。
 背景技术
在现有技术中，液晶显示器得到了广泛应用，液晶显示器通常包含背光模块、液晶显示面板等。由于液晶显示器中的印刷电路板与液晶显示面板相连，且连接的部分为柔性自动卷带式芯片接合（TAB，Tape Automated Bonding）的封装结构设计，因此，印刷电路板的固定是液晶显示器设计中非常重要的一环。
目前已有的印刷电路板固定方式有：
1. 直接采用螺丝固定。在胶框上开孔，用螺丝将电路板固定在背板上，同时达到接地的目的。这种固定的方式不可避免地要采用一定数量的螺丝，而且通常的电路板会放在背板的侧面，不方便螺丝固定，造成锁螺丝工序的效率比较低。因此，这种固定方式成本高，装配工时长。
2. 多加卡子零件固定。增加卡子零件，然后用导电性泡棉与前框接地或者后框接地。显然，此种连接中多了卡子和泡棉等零件，而且泡棉需要增加一个工序进行安装。所以，此种连接方式零件多，成本高，装配工时长。
3. 仅用泡棉固定。直接把电路板放在期望中的位置，采用导电性泡棉与前框接地或者后框接地，同时利用泡棉固定电路板，并缓冲外力对电路板及周边零件。此种连接方式需要泡棉较厚较多。

 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：
如图1及图2所示，一种液晶显示器，包含：一背板10，具有一背板本体12，所述背板本体12上设置至少一弹性薄片20，所述弹性薄片20为拱形，拱顶部位为支撑部20a；一电路板50，具有一接地区(例如所述电路板50内表面上的电路)，所述电路板50设置在所述背板本体12的外侧，且所述接地区与所述弹性薄片20的支撑部20a相接触；一液晶显示面板60，与所述电路板50相连；以及一胶框30，具有若干个侧壁30a和一顶壁30b，所述电路板50配置于所述侧壁30a内侧，所述液晶显示面板60配置于所述顶壁30b下方，所述侧壁30a设置有至少一卡勾40，所述胶框30与卡勾40抵接在所述电路板50的表面上，电路板50与卡勾40抵接的表面与其接地区所在的表面相对，从而卡勾40与所述弹性薄片20配合，弹性夹持固定所述电路板50。
参见图2及图3所示，在本发明的一个具体实施方式中，所述弹性薄片20两端边缘向内设置有折边21，所述背板本体12上设置有组装孔11，所述弹性薄片20利用所述折边21与所述组装孔11配合固定在所述背板本体12上。在本具体实施方式中，所述折边21的数量为4个，对称设置于所述弹性薄片20底部的四角，使得弹性薄片20与背板本体12的结合稳固。如图5所示，弹性薄片20两端边缘的折边21还可以由边缘向外设置。
在本发明的其他实施方式中，所述弹性薄片20也可以省略所述折边21，并进一步通过螺丝锁附固定于所述背板本体12上，或者通过胶条(tape)粘贴固定于所述背板本体12上。
参见图1所示，所述电路板50在其边缘与所述卡勾40对应的位置处形成一开槽51。开槽51能使得卡勾40的固定效果更佳，以防所述电路板50产生滑动而意外脱离所述胶框30的侧表面30a。
