[0042] 本实施例中， 显示屏 1的背面设有遮光层和未被遮光层覆盖的透光部， 透光部 为按键识别符号的形状。 导光板 2内的光线通过透光部呈现发光的灯光效果， 透 光部也就是显示屏 1的触摸区， 触摸膜位于与透光部对应的电脑上的区域。
[0043] 参阅图 4-图 10， 是本发明所提出的触摸导光结构的第二个实施例， 本实施例中 的触摸导光结构为设置在洗衣机上的触摸电源按键， 触摸导光结构安装固定在 洗衣机的主控板 10上， 实现电源按键的触摸发光显示功能。
[0044] 本实施例中， 触摸导光结构具有与第一个实施例相同的结构， 包括从前向后依 次设置的触摸屏 1、 导光板 2和电脑板 3， 在触摸屏 1的感应区所对应的电脑板 3的 前端面区域贴附有触摸膜。 显示屏 1作为装饰板设置在主控板 10的前端面上， 为 了实现导光板 2与显示屏 1的贴合、 或者说紧密接触， 在主控板 10上幵设有避让 通孔 101， 这样可以实现在显示屏 2的后方依次贴合设置导光板 2、 电脑板 3。
[0045] 本实施例中， 参见图 7所示， 在避让通孔 101的左右两侧设有卡合电脑板 3的卡 合结构 102， 使得电脑板 3固定在主控板 10上； 由于导光板 2固定在电脑板 3上， 这样触摸屏 1、 导光板 2和电脑板 3都固定在了主控板 10上。
[0046] 本实施例中， 参见图 4和图 10所示， 为了使得触摸屏 1、 导光板 2和电脑板 3之间 贴合紧密， 触摸导光结构还包括设置在电脑板 3后方的压紧部件 4， 压紧部件 4给 电脑板 3施加向前的力， 使得触摸屏 1、 导光板 2和电脑板 3之间压紧， 贴合紧密 ， 保证了触摸的灵敏性， 以及增加触摸屏 1与导光板 2之间的透光性， 避免串光
[0047] 本实施例中， 参见图 7所示， 压紧部件 4卡合固定在主控板 10的后端面上， 主控 板 10上设置有与压紧部件 4的端部相匹配的挡止槽口 103和卡合爪 104， 这样使得 压紧部件 4牢固的固定在主控板 10上。 参见图 5所示， 压紧部件 4具有压紧本体 41 、 以及向前延伸的弹性爪 42; 当压紧部件 4卡合固定到主控板 10后， 弹性爪 42具 有一定弹性变形的压紧在电脑板 3的后端面上； 使得弹性爪 42施加给电脑板 3向 前的力， 使得触摸屏 1、 导光板 2和电脑板 3之间紧密贴合。
[0048] 本实施例中， 触摸屏 1为玻璃材质的平板， 有利于提升洗衣机的外观形象， 以 及透光性好。 触摸屏 1上的透光部为方框形的按键、 以及位于方框内的电源符号
[0049] 以上所述， 仅是本发明的较佳实施例而已， 并非是对本发明作其它形式的限制 ， 任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为 等同变化的等效实施例。 但是凡是未脱离本发明技术方案内容， 依据本发明的 技术实质对以上实施例所作的任何简单修改、 等同变化与改型， 仍属于本发明 技术方案的保护范围。
