为了更清楚地说明本发明实施例的技术方案，下面将对实施例描述中所需要使用的附图 作筒单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些实施例， 对于本领域的 普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他附图。
图 1为现有技术提供的电子签名工具的结构示意图；
图 2为本发明实施例一提供的电子设备的结构示意图一；
图 3为本发明实施例一提供的电子设备的结构示意图二；
图 4为本发明实施例一提供的电子设备的结构示意图三；
图 5为本发明实施例二提供的电子设备的结构示意图一；
图 6为本发明实施例二提供的电子设备的结构示意图二。 具体实施方式
下面结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。 基于本发明的实 施例， 本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例， 都属于 本发明的保护范围。 下面将结合附图对本发明实施例作进一步地详细描述。
实施例一
如图 2、 图 3和图 4所示， 一种电子设备， 包括显示屏 7 , 该显示屏可以为液晶显示屏； 显示屏 7下方还设有反光体 6, 同时电子设备中还设有提供背光的光源 3,光源 3—般采用 LED 灯。 所述反光体 6的上表面经表面处理为反光面 61 , 反光面 61用于将光源 3的光线反射到显 示屏 7下表面的， 所述反光面 61与所述显示屏 7下表面相对， 所述设有反光面 61的反光体 6用 于替换现有技术中的背光板组件并为显示屏 7提供背光。 去掉了背光板组件结构， 使得设备 的结构更加筒单， 组装更加筒易， 并且造价更低， 同时能完全达到现有的屏幕亮度， 满足用 户使用。
本例中， 所述反光体 6的反光面 61与所述显示屏 7之间形成空腔 12; 所述光源 3设置于所 述空腔 12的侧方。 这一空腔 12采用空气为光的传播介质， 减轻了设备的重量， 同时解决了 现有技术采用有机玻璃等透明材料为光的传播介质对材料透光性要求高的缺点。
本例中， 所述的反光面 61 包括延伸面 10 , 延伸面 10就是设于显示展 7下方边缘超出 显示屏 7下表面的那一部份反光面 61 ; 这情况下， 所述光源 3设置于延伸面 10上方， 如图 3所示。 这种结构的优点是可以将光源 3设于显示屏 7的侧面， 可以减小反光体 6的反光面 61与所述显示屏 7之间形成的距离， 进一步地缩小了设备的体积。 当然光源 3可以设置于 电子设备中的任何位置， 只要其灯光能照射到反光体 6的反光面 61就可以了， 解决了现有 技术光源需固定设于有机玻璃等起导光作用的透明材料侧面的问题， 使结构设计更加灵活。 光源 3可以固定在电路板 2上， 电路板 2在图 2与图 3中未表示， 请参考图 5, 直接由电路 板 2供电工作， 也可以固定于后壳体 1或前壳体 9上， 再通过导线供电工作。
这了更好地实现光的反射， 所述的反光面 61与所述显示屏 7之间距离从靠近光源 3侧到 远离光源 3侧逐渐减小。 所述的反光面 61可以为平面， 形成一个倾斜面； 所述的反光面 61也 可以为曲面， 为内凹或外凸的曲面， 反光面 61与所述显示屏 7之间的距离从曲面边缘到曲面 中心逐渐增加； 更加有利于光线的反射。
另外， 反光体 6的反光面 61上设置有点状或线状漫反射突起或凹陷。 其反光体 6的材料 可以采用金属如铝、 也可以采用塑料， 使用时最好对其表面进行处理， 面表面处理通常采用 表面镀膜或表面抛光处理。 使反光体 6的反光面 61将光源 3的灯光反射至显示屏 7背面形成背 光。反光面 61的整体形状与表面的点状或线状漫反射突起或凹陷应该按照光学的基本反射原 理制作， 以能保证为显示屏 7提供合适的背光为准， 可以通过理论设计结合实验完成， 是本 领域的普通技术人员无需创造性劳动者就可以顺利完成的， 不再详述。
上述的， 表面处理还可以是喷涂于反光面 61上的反光材料， 反光材料可以是荧光漆、 银粉漆等等。这方案通常是在反光面 61上直接制作出点状或线状漫反射突起或凹陷，再进行 喷涂反光膜。
为了防止光源 3光线透出设备壳体， 本设备还包括遮光板 13, 用于阻挡光源 3光线照射 于壳体上， 或者， 直接采用不透光的材料制作壳体。 一个筒易的方式是所述的遮光板直接使 用电路板 2, 而光源 3设于电路板 2上， 结构筒单。
另外， 为了更加有效的利用光源 3所述的遮光板 13靠近光源 3—面附着有反光膜 11。 反 光膜 11固定在遮光板 13的下面， 一般采用粘贴或喷涂的方式。 反光膜 11上设置有点状或线 状漫反射突起或凹陷。 其材料可以采用金属箔如铝箔、 也可以采用塑料薄膜， 还可以采用塑 料薄膜表面镀反光膜， 还可以为纸质膜， 不过最好在纸质膜表面镀反光膜。 反光膜 11的作用 是将光源 3的灯光反射（也可以是折射、 散射、 透射） 至反光体 6的反光面 61上。
另外， 本例中的反光体 6固定于所述设备的壳体上。 反光体 6可以是板状， 如图 2所示固 定于后壳体 1上的胁板上， 也可以是块状， 如图 3所示固定（粘贴） 于后壳体 1表面， 当然还 可以通过卡扣等限位结构固定在后壳体 1上，或者通过卡扣等限位结构扣在前壳体 9或者电路 板 2上。 具体的固定方式为本领域普通技术人员熟知， 不再描述。
本例的结构， 设备的壳体包括后壳体 1与前壳体 9, 显示屏 7设于前壳体 9开窗处内 侧， 后壳体 1与前壳体 9之间空间内设有电路板 2。 实施例二
如图 5与图 6所示， 一种电子设备， 与实施例一不同的是， 在实施例一的各方案基础上， 所述的显示屏 7下表面还贴有导光膜 4。 导光膜 4可以采用半透明膜。 导光膜 4的材料可以为 塑料或纸。 该导光膜 4还可以将反光体 6的反光面 61上反射的光进行弱化、 平均化、 柔化等， 令显示屏 7的光更加柔和清晰。
以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不局限于此， 任何 熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到的变化或替换， 都应涵 盖在本发明的保护范围之内。 因此， 本发明的保护范围应该以权利要求书的保护范围为准。
