摘要： A method for removing heat from a spatial light modulator device in a digital projection display by encapsulating the device package in a thermal conductive socket attached to a printed wiring board. The socket wraps around the device package to remove both optically generated heat from the front of the device and electrically generated heat within the device. In higher brightness projector applications, fins are added to the socket to increase the mass and surface area of the socket, thereby improving the heat dissipation properties of the system. The heat sink socket attaches to the printed wiring board using a screw attachment means, which also assures electrical connectivity to the spatial light modulator through a interposer element between the device and spatial light modulator. This approach completely eliminates conventional heat sinks, mounting studs, and fasteners, which have been failure mechanisms in these type displays.

摘要： This invention concerns reducing fan noise and preventing a light source, an optical element, and the like from deteriorating in a projector display device. The projection display device includes a light-source lamp unit, an optical system unit having a modulation device, a projection lens for enlarging and projecting an image formed by the optical system, a power supply unit for supplying electric power for driving the device, power supply intake fans, a modulation device intake fan, and exhaust fans. Fan noise can be reduced by driving only the power supply intake fans for a predetermined period after the device is powered on. Furthermore, the light-source lamp, the optical elements, and the like can be prevented from deteriorating by controlling the rotation speeds of the other fans based on detected temperatures detected by temperature sensors.

摘要： A projection display apparatus employing organic EL elements is presented that is light in weight, is small in size, and can be practically implemented. In particular, the apparatus suppresses light-emission performance degradation caused by generated heat, thereby extending useful life, stabilizing brightness, and securing continual maximum brightness. The apparatus comprises; liquid crystal panels 12R, 12G, and 12B; light emitting units 13R, 13G, and 13B, positioned at the back of the liquid crystal panels and provided with organic EL elements as light emitting layers; and cooling bodies 14R, 14G, and 14B, positioned at the back of the light emitting units, for dispersing the heat generated by the light emitting layers. The cooling bodies 14R, 14G, and 14B may, for example, be electronic cooling elements that employ the Peltier effect to absorb and radiate the generated heat. Alternatively, the cooling bodies may be configured as heat-dispersing fins that guide and disperse generated heat.

摘要： A projector is provided that includes a cooling structure which efficiently cools an electrooptic device, and which can cope with an increase in brightness of a light source and a reduction in size of the projector. A cooling fan for introducing cooling air is mounted above an air inlet, and a regulating fan for regulating the cooling air introduced by the cooling fan is mounted at a position opposing the cooling fan across an electrooptic device. For this reason, the cooling air is formed in a substantially linear shape, and the electrooptic device can be uniformly and efficiently cooled without cooling only parts of the electrooptic device. This allows a cooling structure to be obtained which can cope with an increase in brightness of a light source lamp serving as a light source and a reduction in size of a projector.
