Description

—种 LED显示屏面罩
技术领域
本发明涉及 LED显示屏领域， 尤其是一种改进了的 LED显示屏面罩。 背景技术
LED显示屏的应用范围越来越广泛， 其可应用在户内外广告、 体育、 交 通、 演出、 展览、 租赁、 集会等各种场合。 目前， 贴片 LED显示屏以其高分辨 率、 高亮度、 视角大等优点， 已经成为室内高中端 LED显示屏的主流产品， 并 逐渐应用到室外 LED屏的高端产品中。 由于贴片 LED显示屏的分辨率较高， 而贴片 LED灯体相对 PCB的高度较小， 因此， 对贴片 LED显示屏的面罩要求 非常严格， 一般而言， LED显示屏面罩需要使得 LED显示屏的可视角度增大， 然而， 目前的贴片 LED显示屏面罩一般采用 PC等工程材料并且表面没有做吸 光、 防反光处理， 当照明光或阳光照射到 LED显示屏的屏体上时， 屏体面罩会 发生反射， 造成眩光现象， 降低了对比度。
因此， 提供一种可以防止眩光并提高对比度的 LED显示屏面罩实属必要。 发明内容
本发明的目的是提供一种 LED显示屏面罩， 旨在解决现有的 LED显示屏 面罩不能有效防止眩光、 对比度较低的缺陷。
本发明是这样实现的， 一种 LED显示屏面罩， 其包括基体和设置于基体上 的外观面， 所述外观面包括若干高遮光沿和低遮光沿， 所述高遮光沿和低遮光 沿之间形成吸光黑缝。
更具体的， 所述基体为玻璃纤维加强型 PC工程塑料制成。
更具体的， 所述外观面由黑色哑光 TPU弹性体材料制成。
更具体的， 所述高遮光沿和低遮光沿是由两个斜面成形一个尖顶。 更具体的， 一个高遮光沿和一个低遮光沿形成一组遮光沿， 两组遮光沿中 间设置若干锯齿状小牙。
更具体的， 所述若干锯齿状小牙之间形成若干小吸光缝。
更具体的， 所述基体和外观面采用双色注射工艺一次注塑成型。
与现有技术相比， 本发明提供的 LED显示屏面罩采用黑色哑光 TPU弹性 体制成外观面， 同时通过吸光黑缝和小吸光缝大量吸收照明光或阳光， 极大程 度的减少了眩光的产生， 提高了对比度。 附图说明
图 1是本发明 LED显示屏面罩的整体结构示意图；
图 2是图 1中沿 A-A剖面线的剖视图；
图 3是本发明所涉及的外观面的结构放大示意图。 具体实施方式
为了使本发明的目的、 技术方案及优点更加清楚明白 , 以下结合附图及实 施例， 对本发明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 仅用以解释本发明， 并不用于限定本发明。
结合参见图 1、 图 2中所示， 图 1是本发明 LED显示屏面罩 1的较佳实施 例的整体结构示意图， 图 2是沿图 1中 A— A剖面线的剖视图， 所述的 LED显 示屏面罩 1 包括玻璃纤维加强型 PC (聚碳酸酯） 工程塑料基体 3和黑色哑光 TPU (热塑性聚氛酯弹性体） 弹性体材料外观面 2, 结合参见图 3 中所示， 所 述外观面 2包括高遮光沿 4、低遮光沿 5、 由高遮光沿 4和低遮光沿 5形成的吸 光黑缝 6、 若干锯齿状小牙 7和小吸光缝 8。
基体 3和外观面 2采用双色注射工艺一次注塑成型， 高遮光沿 4、 低遮光 沿 5由两个斜面成形一个尖顶， 高遮光沿 4与低遮光沿 5中间形成一条吸光黑 缝 6; 锯齿状小牙 7由两个大角度斜面形成一个尖顶， 两个相邻锯齿状小牙 7 之间形成一条小吸光缝 8。 本发明 LED显示屏面罩 1由上至下包括多条吸光黑 缝 6和多条小吸光缝 8。
由于本发明 LED显示屏面罩 1的较佳实施例采用了双色注射成型的方案， 面罩的基材 1采用玻璃纤维加强型 PC工程塑料，而外观面 2采用黑色哑光 TPU 弹性体， 能够有效避免眩光， 同时， 面罩外观面 2从上至下每个象素间有一高 一低的一组水平遮光沿 （高遮光沿 4、 低遮光沿 5 ), 每两组遮光沿中间有锯齿 状小牙 7, 而相邻锯齿状小牙 7之间形成一条小吸光缝 8, 所有遮光沿的顶部为 尖角， 通过吸光黑缝 6和小吸光缝 8可以大量吸收照明光或阳光， 也极大程度 的减少了眩光的产生， 提高了对比度。
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。 例如， 高 遮光沿 4和低遮光沿 5的具体排布方式并不局限于图中所示， 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， 均应包含在本发明权利要 求的保护范围之内。
