Description

便携式显示装置 说明书
便携式显示装置
技术领域
本发明涉及一种显示装置，尤其是涉及一种便携式显示装置。
背景技术
一般便携式显示装置包括背光模组及液晶模组。背光模组位于液晶模组的一侧，用以提供光束，从背光模组发出的光束经液晶模组之后转换为影像而显示。
然而，由于背光模组及液晶模组较为耗电，生产企业或使用者在追求大屏幕的同时，同时也使得便携式显示装置的重量与耗电量 提高。并且，在一般的便携式显示装置中，背光模组及液晶模组所占的成本亦较高 。
发明内容
有鉴于此，有必要提供一种可以减少耗电量的便携式显示装置。
一种便携式显示装置，其包括壳体、显示屏，该显示屏设于该壳体上，该壳体内具有容纳腔，该便携式显示装置还包括微投影模组，该微投影模组设于该壳体内的容纳腔并与该显示屏相对应，该微投影模组用于提供影像光束并投影到该显示屏上。
上述便携式显示装置包括微投影模组，通过微投影模组将影像光束投射到显示屏上，无需使用背光模组及液晶模组，减少了能量损失，因此有利于降低便携式显示装置的耗电量。
附图说明
图 1 为本发明第一实施例的便携式显示装置的示意图。
图 2 为图 1 所示便携式显示装置沿 II-II' 剖开的剖面图。
图 3 为本发明第二实施例的便携式显示装置的示意图。
图 4 为本发明第三实施例的便携式显示装置的示意图。
图 5 为本发明第四实施例的便携式显示装置的示意图。
图 6 为本发明第五实施例的便携式显示装置的示意图。
具体实施方式
以下将结合具体实施方式对本发明的便携式显示装置进行进一步的说明。
请参见图 1 与图 2 ，本发明第一实施例的便携式显示装置 100 包括壳体 11 、显示屏 12 及微投影模组 13 。显示屏 12 设于壳体 12 。壳体 12 的内部具有容纳腔 122 ，微投影模组 13 设于壳体 11 内的容纳腔 112 并与显示屏 12 相对应。微投影模组 13 用于提供影像光束 130 并投影到显示屏 12 上。
具体在本实施例中，微投影模组 13 的设置与壳体 11 内部的尺寸与配置相适应，微投影模组 13 可使用超短焦系统的投影模组，其可将影像光束 L 在壳体 11 的内部就投射于显示屏 12 并在显示屏 12 清晰成像。
微投影模组 13 可包括照明单元、光阀及成像镜头。照明单元可用于提供照明光束，光阀可设于照明光束的传递路径上，以将照明光束转换为影像光束 L ，成像镜头设于影像光束 L 的传递路径上，且位于光阀与该显示屏之间。其中，照明单元可包括发光二极管或激光光源。
上述便携式显示装置 100 包括微投影模组 13 ，通过微投影模组 13 将影像光束 L 投射到显示屏 12 上，无需使用背光模组及液晶模组，减少了能量损失，因此有利于降低 便携式显示装置 100 的耗电量。并且采用的微投影模组 13 质量较小，成本也较低，因此还可以降低 便携式显示装置 100 的重量及成本，以更加适合市场及使用的需求。
请参加图 3 ，所示为本发明第二实施例的便携式显示装置 200 ，便携式显示装置 200 与便携式显示装置 100 相似，其不同点在于：便携式显示装置 200 的壳体 21 具有凸出部 214 。凸出部 214 位于壳体的一端侧，微投影模组 23 位于 凸出部 214 内。详细来说，凸出部 214 与壳体 21 的侧面 215 相连的部分的表面的截面为直角结构，与底面 216 相连的部分的表面截面为弧形结构。这样的凸出部 214 不仅可以增加微投影模组 23 与显示屏 22 之间在竖直方向（垂直底面 216 的方向）的距离，改善投影效果，而且还可以增加 便携式显示装置 200 的美感。
请参加图 4 ，所示为本发明第三实施例的便携式显示装置 300 ，便携式显示装置 300 与便携式显示装置 100 相似，其不同点在于：便携式显示装置 300 在显示屏 32 上还设有触控模组 322 。触控模组 322 可为电容式或光学式触控模组。
请参加图 5 ，所示为本发明第四实施例的便携式显示装置 400 ，便携式显示装置 400 与便携式显示装置 100 相似，其不同点在于：便携式显示装置 400 还包括反射元件 44 ，微投影模组 43 与反射元件 44 位于壳体 41 内相对的两侧；微投影模组 43 所产生的影像光束可先照射到反射元件 44 ，然后反射元件 44 再将影像光束反射到显示屏 42 上。其中，反射元件 44 可为平面镜、凹面镜或凸面镜。
请参加图 6 ，所示为本发明第五实施例的便携式显示装置 500 ，便携式显示装置 500 与便携式显示装置 400 相似，其不同点在于：便携式显示装置 500 包括的反射元件 54 位于壳体 51 内的中部，微投影模组 53 所产生的影像光束可先照射到反射元件 54 ，然后反射元件 54 再将影像光束反射到显示屏 52 上。其中，反射元件 44 可为 5 凸面镜。由于反射元件 54 位于壳体 51 的中部位置，其与微投影模组 53 之间的距离相对较短，且反射元件 54 与显示屏 52 上各处的距离也可减小，因此有利于减小壳体 51 的厚度，从而进一步减少 便携式显示装置 500 的尺寸。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
