    • An electronic display which can be serviced without having to remove the display from its mounted position. A front housing and a rear housing are hingedly attached so that the front housing can rotate and allow access to the interior of the display. An axial force mechanism can be used to aid in rotating the front housing to an open position. A locking collar, support member, or axial locking member may be used to ensure that the front housing remains open. A removable front glass assembly or removable glass panel may be used with an exemplary embodiment. The front glass assembly or glass panel can be easily replaced if it becomes damaged by minimally- trained personnel. Gutters may be used between the front and rear housing as well as the front housing and front glass assembly to ensure an adequate seal against contaminates.
    • 一种电子显示器,可以在不必将显示器从其安装位置移除的情况下进行维修。 前壳体和后壳体铰接地连接,使得前壳体可以旋转并允许进入显示器的内部。 可以使用轴向力机构来帮助将前壳体旋转到打开位置。 可以使用锁定环,支撑构件或轴向锁定构件来确保前壳体保持打开。 可以使用可拆卸的前玻璃组件或可移除的玻璃面板,其中示例性实施例。 如果受到受过训练的人员造成损坏,前玻璃组件或玻璃面板可以轻松更换。 可以在前壳体和后壳体以及前壳体和前玻璃组件之间使用沟槽,以确保对污染物的足够的密封。

    • An LED circuit using a combination of series and parallel arrangements for optimum current sharing between LEDs. The current paths allow an LED to fail without resulting in other LEDs failure or noticeable luminance variance across the circuit. Some embodiments use metallic PCB technology which permits optimum thermal regulation of heat generated by the LEDs. Exemplary embodiments can be used with a single-layer PCB where only one layer of conducting material must be placed on the substrate. This results in a thinner, lighter, and cheaper assembly. The rear surface of the PCB may contain heat sinks or fins and may have air (or other gaseous matter) moved across the surface and/or heat sinks to facilitate cooling of the assembly. An LCD assembly using the same is also disclosed.
    • 采用串联和并联配置组合的LED电路,可实现LED之间的最佳电流分配。 电流路径允许LED发生故障,而不会导致其他LED发生故障或整个电路发生明显的亮度变化。 一些实施例使用金属PCB技术,其允许由LED产生的热量的最佳热调节。 示例性实施例可与单层PCB一起使用,其中仅一层导电材料必须放置在基板上。 这导致更薄,更轻,更便宜的组件。 PCB的后表面可以包含散热器或散热片,并且可以具有移动穿过表面和/或散热器的空气(或其他气体物质)以促进组件的冷却。 还公开了使用其的LCD组件。
