A system includes a display panel, a temperature sensor configured to measure a temperature of the display panel, a thermoelectric device coupled to the display panel and configured to transfer heat to or from the display panel, and a controller electrically coupled to the temperature sensor and the thermoelectric device. The controller is configured to receive the measured temperature of the display panel and, based on the measured temperature of the display panel, send a second signal to the thermoelectric device to cause the thermoelectric device to remove a first quantity of heat from the display panel or send a third signal to the thermoelectric device to cause the thermoelectric device to provide a second quantity of heat to the display panel.

An electronic device includes a first duct for guiding the air blown out from blowers for cooling a liquid crystal panel mounted on an illumination optical system to the liquid crystal panel, a second duct for guiding the air passing through the liquid crystal panel in the opposite direction of the air blown out from the blowers, a heat sink for removing heat from the air passing through the second duct and a blower holding unit for holding the blowers are provided in a dust-proof case, and the top surface of the blower holding unit, the blower holding unit forms a third duct for guiding the air from which heat has been removed by the heat sink to the air inlet of the blowers that is a space formed along the top surface of the dust-proof case.

An optical component according to the present disclosure includes a substrate containing sapphire. The substrate is provided with a functional portion and a heat dissipating portion. An inclination of a main face of the substrate is 75° or greater with respect to a c-plane of the sapphire. The functional portion and the heat dissipating portion are provided so that an angle formed by a c-axis of the sapphire and a line segment connecting the functional portion and the heat dissipating portion is 15° or less.

Provided is a display device. The display device includes a housing including a front glass and a rear cover, a display panel arranged within the housing, and an air circulator arranged behind the display panel for circulating air between the front glass and the front surface of the display panel, wherein the air circulator includes a circulation fan circulating air, a case receiving the circulation fan and having open top to discharge air in a direction of long edges of the display panel, a first connection part formed to be open at one end of the case in the direction of long edges, and a second connection part formed to be open at the other end of the case in the direction of long edges.

Systems for forced air cooling of display assemblies are provided. An electronic display subassembly is located behind a cover and includes an interior channel. An open loop centrifugal fan is positioned at an intake or an exhaust and forces ambient air through an open loop pathway when activated. A closed loop airflow pathway encircles the electronic display subassembly. A closed loop centrifugal fan is positioned at a side channel and forces circulating gas through the closed loop airflow pathway. Electronic components for operating the display assembly are provided with the rear compartment.

A display assembly with integrated electric vehicle charging equipment includes a first and second side assembly connected to a structural frame, each including an electronic display subassembly located behind a cover. The electric vehicle charging equipment is connected to the structural frame between said first and second side assemblies in an at least partially recessed manner. Open or closed loops of air may be provided for cooling the first and second side assemblies and the electric vehicle charging equipment, which may all be connected to a common power source.

Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.

The present disclosure provides a display device, including a housing, an air tunnel, and a functional device. The housing includes an air inlet and an air outlet, wherein the air inlet and the air outlet are disposed on two sides of the housing opposite to each other. The air tunnel is disposed in the housing and extends from the air inlet to the air outlet; and the functional device is disposed in the housing and located outside the air tunnel.

A device includes a micro-organic light emitting diode (μ-OLED) display panel and an electronic component. An electrical connector electrically couples the μ-OLED display panel and the electronic component. A standoff is disposed between the electronic component and the μ-OLED display panel. The standoff physically couples the electronic component and the μ-OLED display panel with a gap therebetween. The gap thermally decouples the electronic component from the μ-OLED display panel. A U-shaped heat sink can be disposed in the standoff, and heat generated by the μ-OLED display can be mitigated by a system fan when a U-shaped heat sink is disposed in the standoff.

A device includes a micro-organic light emitting diode (.Math.-OLED) display panel and an electronic component. An electrical connector electrically couples the .Math.-OLED display panel and the electronic component. A standoff is disposed between the electronic component and the .Math.-OLED display panel. The standoff physically couples the electronic component and the .Math.-OLED display panel with a gap therebetween. The gap thermally decouples the electronic component from the .Math.-OLED display panel. A fan that is integrated with the .Math.-OLED display panel is placed in the standoff and actively cools the display panel. When the fan provides air flow over the .Math.-OLED display panel, heat generated by the .Math.-OLED display is mitigated by cooling air.
