所述背光模组产生的发散的光在所述液晶面板4板面处均匀照射在液晶面板4上,形成比较均匀稳定的背光光源。
实施例四:
本实施例包括了实施例三的内容,并且如图1至图8所示,在本实施例中,所述背光模组为长条形,所述背光模组还包括槽长与背光模组长度方向一致的光源卡槽3,所述光源1设置在所述光源卡槽3的槽底31,所述扩散板2设置在所述光源卡槽3的槽口32,所述液晶面板4与所述背光模组长度方向对应的两条板边各设有一条液晶面板框5,两条液晶面板框5分别与光源卡槽3宽度方向的两侧之间设有支撑件。本实施例中,所述光源卡槽3为由槽底31和槽底31两侧的槽壁形成的截面为U形的槽体。
在本实施例中,所述支撑件包括前板6和背板7,所述前板板面第一端61与所述光源卡槽3宽度方向的一侧枢转连接、与所述前板板面第一端61相对的前板板面第二端62可拆卸地支撑于对应液晶面板框5朝向背光模组的一侧;所述背板板面第一端71与所述光源卡槽3宽度方向的另一侧枢转连接、与所述背板板面第一端71相对的背板板面第二端72与对应液晶面板框5朝向背光模组的一侧枢转连接。在本实施例中,前板6与光源卡槽3之间、背板7与光源卡槽3和液晶面板框5之间的枢转连接是分别通过第一轴承8、第二轴承9和第三轴承10实现的;在本发明的其它实施例中,也可通过其它结构来实现。

使得液晶面板4、前板6和背光模组通过所述第一轴承8、第二轴承9和第三轴承10相对旋转,本实施例还可以为如图5至图8所示的展开状态,所述背板7支撑于所述液晶面板4和背光模组的底部,前板6支撑于所述液晶面板4和背光模组的顶部,前板6和背板7之间形成与扩散板的光扩散方向一致的夹角。并且展开后的液晶面板4被立起支撑至一定角度,方便用户使用。本实施例中,背光模组的光源为LED灯条,使用时点亮LED灯条中的LED灯并给液晶面板4输入视频信号,LED灯产生的光经过扩散板的扩散作用,均匀地投射到液晶面板4上从而成像。
综上所述,本发明的背光模组组件少,成本低;具有所述背光模组的显示装置具有超薄,易携带的特点。
以上实施方式仅用于说明本发明,而并非对本发明的限制,有关技术领域的普通技术人员,在不脱离本发明的精神和范围的情况下,还可以做出各种变化和变型,因此所有等同的技术方案也属于本发明的范畴,本发明的专利保护范围应由权利要求限定。
