    Abstract: A display assembly includes a housing which at least partially encloses an image assembly. A cover positioned forward of, and spaced apart from, the image assembly forms at least a portion of a forward surface of the housing and permits viewing of images displayed at the image assembly therethrough. A fan assembly moves air through an airflow pathway within the housing which includes a front channel between the cover and the image assembly and a rear chamber behind the image assembly. One or more solar energy reduction layers are associated with the cover and prevent at least some ambient sunlight striking the cover from traveling therebeyond.

    Abstract: Described herein are exemplary embodiments of a light guide assembly for a backlight and backlight assemblies using such light guide assemblies. An exemplary backlight assembly may have a light guide with a pair of opposing edges and a sliding LED subassembly placed along an edge of the light guide and attached to the light guide so that movement of the light guide causes movement of the sliding LED subassembly. In some embodiments, a first slot may be positioned within the light guide where a post extends from the sliding LED subassembly to engage with the first slot in the light guide. In some embodiments, a back pan may be positioned behind the light guide where a post can extend from the back pan to engage with a second slot in the light guide.

    Abstract: A display assembly which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. An airflow pathway travels through the housing and is configured to accept, circulate, and exhaust air by way of one or more fans. One or more sensors measure characteristics of the air. Weather conditions for a location of the display assembly are gathered, measurements from the sensors are received, and a determination is made as to whether the measurements of the ingested air are within a margin of error expected measurements derived from the gathered weather conditions. An alert is generated if the measurements of the ingested air are not within the margin of error.

    Abstract: Exemplary embodiments disclosed herein provide a LCD assembly including an LED backlight, a liquid crystal display (LCD) placed in front of the LED backlight, a glass plate positioned between LED backlight and the LCD; and an optical film positioned between the glass plate and the LCD. In some embodiments, the glass plate is bonded to the rear side of the LCD, generally around the perimeter of the LCD. Preferred embodiments place a diffusing film within a cavity that is defined between the glass plate and the LCD. Some embodiments also bond the backlight cavity walls to the glass plate, on a side opposing the LCD.

    Abstract: Systems and methods for cooling an electronic image assembly are provided. A transparent panel forms a front portion of a housing for the electronic image assembly. The transparent panel is located forward of, and at least some distance from the electronic image assembly. An airflow pathway passes through the housing between said electronic image assembly and said transparent panel. An air circulation device forces air through the airflow pathway. At least one polarizer located at the transparent panel is configured to reduce solar energy entering said airflow pathway.

    Abstract: An assembly for an electronic display includes a digital side assembly and an access panel mounted to a frame. The digital side assembly includes a housing, a display layer located behind a cover panel, a front channel between the display layer and the cover panel, and a side assembly open loop channel behind the display layer. A cooling channel is located between the frame and the rear surfaces of the access panel and the digital side assembly. An open loop pathway for ambient air includes the side assembly open loop channel and an access panel open loop channel. A closed loop pathway for circulating gas includes the cooling channel and the front channel.

    Abstract: Systems and methods are provided for monitoring the status of a touchscreen at a display assembly. Signals are transmitted to the touchscreen. Where signals to the touchscreen are interrupted for at least a predetermined amount of time, a type and location of damage are identified. A visual representation reflecting the type and location of damage at the touchscreen is generated.
