本发明的最佳实施方式
[14]
本发明的实施方式
[15] 为了使本实用新型的目的、 技术方案及优点更加清楚明白， 以下结合附图及实 施例， 对本实用新型进行进一步详细说明。 应当理解， 此处所描述的具体实施 例仅仅用以解释本实用新型， 并不用于限定本实用新型。
[16] 图 3显示了本实用新型一较佳实施例提供的彩虹显示装置 19， 用于液晶显示屏 ， 包括导光板 191、 LED (发光二极管） 192和电路板 193、 光反射材料 194和控制 电路 195。 导光板 191具有出光面 1911和与之相背的字符面 1912， 因根据液晶显 示屏的需要设于字符面 1912上， 这样， 字符 4不容易被触摸而因此保持得更长久 。 本实用新型中字符 4包括液晶显示屏上调节按键的名称符号或所需要的其它字 符。
LED192焊接在电路板 193上且位于导光板 191上方， 并与电路板 193电连接。 光反 射材料 194位于
电路板 193上方， 控制电路 195设于光反射材料 194上方， 并供给 LED电源并且按 照设定的程序控制 LED亮度变化或 LED色彩变化， 光反射材料 194使 LED192向外 发出的光反射到导光板 191内， 使光得到充分利用， 使导光板 191上字符 4突出显 示出来， 使该字符面 1912在距离稍远或者在光线较暗吋也能看清， 而且具有装 饰效果， 使液晶显示屏显得更加美观、 高档。
[17] 在本实施例中， 字符 4的突出显示有两种方式， 一种是将字符 4注塑、 印刷或刻 制于字符面 1912上且形成折射凸点或折射凹坑 （图中未示出） ， 从而高亮度显 示字符 4， 低亮度显示导光板其余部分。 另一种是通过在字符面 1912上除字符外 的其余地方， 注塑、 印刷或刻制折射凸点或折射凹坑 （图中未示出） ， 从而低 亮度显示字符 4， 高亮度显示导光板其余部分。
[18] 在本实施例中， LED192发出的光为红色、 绿色、 蓝色、 黄色和白色中之任一 种；
或为红色、 绿色、 蓝色、 黄色和白色中之任两种； 或为由红色、 绿色、 蓝色三 基色组成。
[19] 图 4、 图 6和图 7显示了本实用新型一较佳实施例的液晶显示屏， 包括显示屏本 体 1、 稳定显示屏本体 1的底座 2和连接于显示屏本体 1和底座 2之间的支撑架 3。 显示屏本体 1包括显示屏壳体， 显示屏壳体包括面板 11和底板 12， 面板 11和底板 12组成一容置空间 5， 面板 11下侧， 设有上述彩虹显示装置 19。 上述容置空间 5 内还设有 LCD (液晶屏）模组
13、 背光源模组 18、 背光源支架 10、 背光源底板 17、 底板连接板 14、 底板支架 1 5和电路板 /电源板 16， 底板连接板 14固定于底板 12上， 电路板 /电源板 16固定于 底板连接板 14上， 底板支架 15—端与背光源底板 17相连接， 另一端与底板连接 板 14相连接， 背光源模组 18—侧与背光源底板 17紧配合， 另一侧与背光源支架 1
0紧配合， LCD模组 13—侧与背光源支架 10紧配合， 另一侧与面板 11紧配合。
[20] 图 5显示了本实用新型另一较佳实施例的液晶显示屏， 与前述实施例的液晶显 示屏相比， 其主要区别在于， 上述实施例中彩虹显示装置 19出光面为矩形， 本 彩虹显示装置 19出光面底边为一弧边， 增强了美感。 当然， 根据需要该彩虹显 示装置 19外形还可以制成其它合适形状。
[21] 需要说明的是， 不管液晶显示屏的部件如何改变， 只要是在面板 11下侧， 设有 上述彩虹显示装置 19的液晶显示屏， 均在本实用新型的保护范围之内。
[22] 以上所述仅为本实用新型的较佳实施例而已， 并不用以限制本实用新型， 凡在 本实用新型的精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含 在本实用新型的保护范围之内。
