METHODS OF AND APPARATUSES FOR REDUCING INFRARED LOADING ON DISPLAY DEVICES

Document Type and Number:

WIPO Patent Application WO1999034250

Kind Code:

A9

Abstract:

Methods of and apparatuses for reducing the solar or infrared loading on display devices. A reflective material (39) is positioned between a radiant energy source (5) and the absorptive material (410) of a display device (400) to reflect wavelengths of radiant energy in the infrared or near-infrared range. The reflective material (30) allows visible radiant energy (60) to be transmitted, while reflecting the infrared radiant energy to reduce the infrared loading on the display device. The present invention reduces the temperature rise of the display device due to infrared loading by reflection rather than absorption of the radiant energy, while preserving the integrity of the visible wavelength range. The reflective material (30) reduces the infrared loading on the display device by up to 50 %.
