Abstract: A display apparatus comprising first and second liquid crystal display (“LCD”) modules, each LCD module comprising an LCD cell and a backlight arrangement which is arranged to provide backlight illumination to an image display screen of the LCD cell; wherein a ventilation channel is defined between the two LCD modules; characterized in that air-moving arrangements are provided to move air across the ventilation channel to dissipate heat generated by the backlight modules during operation. Such arrangements facilitate the implementation of ultra-bright LCD displays which could function well under bright sunlight while alleviating over-heating issues due to a high intensity of backlight illumination.

Abstract: A system for cooling an electronic image assembly using a heat exchanger with an internal fan assembly. Circulating gas may also be used to cool a front portion of the electronic image assembly or any other internal cavity of the electronic display housing. The circulating gas may be drawn through a heat exchanger so that heat may be transferred to an ambient gas. The heat exchanger may have an internal fan assembly for drawing ambient air through the heat exchanger and exhausting it out of the display housing. The heat exchanger may be divided into two portions so that the fan assembly is placed between the two portions.

Abstract: A multi-panel electronic display for use on a structure, comprising a frame removably attached to the structure in such a way as to encounter a natural airflow, a plurality of individual panels mounted on the frame, each panel comprising a first side and a second side opposite the first side, the first side comprising a plurality of light sources, wherein each individual panel works with other individual panels to display an image, and a printed circuit on the second side of more than one of the individual panels of the multi-panel electronic display and in thermally conductive communication with the frame such that heat generated by electronic components on the circuit board is dissipated within the frame and such that the frame is cooled by the natural airflow. The frame may be corrugated to facilitate dissipation of the heat and create space for electrical wiring, and thermally conductive pads may be inserted between the circuit board and the frame to further dissipate heat. A 12 volt, 24 volt, or greater power source can be stepped down to 5 volts on the panel itself, outside the structure, to minimize holes needed in the walls of the structure.

Abstract: An electronic display which can be mounted above a paved surface in an outdoor environment. A surface or plate is placed behind the electronic display to define a gap where cooling air can be drawn through said gap in order to cool the electronic display. A plurality of ribs may be placed within the gap and in thermal communication with the electronic display. The density of the ribs may be varied according to the inlet and exhaust openings for the cooling air. The ribs may be placed at a higher density near the exhaust to account for the increase in temperature of the cooling air as it travels through the gap.

Abstract: There are provided a backlight capable of improving luminance efficiency (brightness efficiency) by devising a structure of a HCFL to allow adjustment of a cold spot temperature, and further provided a liquid crystal display device using the backlight. A distance (cathode length) between one tube end portion and one filament of a pair of filaments is set longer than a distance (cathode length) between the other tube end portion and the other filament. In this manner, at least the tube end portion on the longer cathode length side can be set as the cold spot. Further, a tube end portion of a hot cathode fluorescent tube is arranged outside a lamp house. In this manner, the cold spot set at the tube end portion of the hot cathode fluorescent tube can be arranged outside the lamp house where the temperature is low, and the cold spot temperature can be decreased.

Abstract: A light flux control member has a back face provided with a first recess portion and ventilation grooves. Output light of the light emitting element arranged as to correspond to the first recess portion enters into the light flux control member via the first recess portion and ventilation grooves being emitted from a light control emission face of the light flux control member after inner-propagation. Refraction of incident light to second recess portions formed in the ventilation grooves hardly generate inner-propagation light which has travelling directions near to a direction of reference optical axis L. This avoids emission from the light control emission face from providing a ring-like bright part. In addition, heat emitted from the light emitting element can be released at a high efficiency because a space in the first recess portion communicates with the outside of the light flux control member.

Abstract translation: 光通量控制部件具有设置有第一凹部的背面和通气槽。 布置成对应于第一凹部的发光元件的输出光经由第一凹部进入光束控制构件，并且在内部传播之后从光束控制构件的光控制发射面发射通气槽。 入射光对形成在通气槽中的第二凹部的折射几乎不产生具有靠近基准光轴L的方向的行进方向的内侧传播光。由此，能够避免来自光控制射出面的发光，从而形成环状亮部 。 此外，由于第一凹部中的空间与光束控制构件的外部连通，所以可以高效率地释放从发光元件发出的热量。

Abstract: A system for cooling an electronic display where an isolating structure may be used to allow ambient air to cool power modules. The isolating structure substantially prohibits containments which may be present within the ambient air from contacting sensitive electrical components on the power modules or otherwise. A gasket may be used to seal the interface between the power modules and the isolating structure. Heat sinks may be placed in thermal communication with the power supplies and fans may draw air through a narrow channel in which the heat sinks are located. In some embodiments the narrow channel may have the opposing surface of the channel defined by the rear portion of an LED assembly. Exemplary embodiments may use the ambient air to cool both the power modules and a closed loop of isolated gas within the electronic display.
