A display device includes a heat sink and an LCD panel having peripheral edges. The LCD panel includes a non-activated area extending inwardly a predetermined distance from the peripheral edges. A thermal link is provided, made from an anisotropic graphite material, and is in thermal contact with the heat sink and with at least a portion of the non-activated area of said LCD panel.

Display device with thermal link

A handheld device (), including a projector module () which includes a light source having a laser or at least one light emitting diode; a thermal management system which includes a heat collector () formed of a material having a thermo-mechanical design constant of at least 10 mm-W/m*K and having a non-planar shape, the heat collector in thermal contact with the light source; a heat spreader () having a surface area at least 1.5 times that of the surface area of the heat collector and a thermo-mechanical design constant of at least 10 mm-W/m*K, the heat spreader positioned in thermal contact with the heat collector, wherein thermo-mechanical design constant of a material is defined by thermal conductivity of the material multiplied by its average thickness.

Thermal management for handheld projectors

A method for reducing temperature-caused degradation of the performance of a digital reader comprising pixels, the method including positioning at least one sheet of compressed particles of exfoliated graphite adjacent to a plurality of the pixels of the digital reader.
