PROBLEM TO BE SOLVED: To provide a display apparatus capable of suppressing temperature increase of a liquid crystal display element even when a high luminance light emission light source is used. SOLUTION: The display apparatus 20 is provided with the liquid crystal display element 26 having a liquid crystal cell wherein a liquid crystal is encapsulated between a pair of light transmissive substrates, a light source (light emitting diode) 22 disposed at the rear of the liquid crystal display element 26 and irradiating the liquid crystal display element 26 with white illumination light and a filter (trimming filter) 25 disposed between the liquid crystal display element 26 and the light source 22 and having ≤50% light transmittance in a prescribed wavelength region showing a color which is not used for display in the three primary colors.

Abstract:
An infrared (IR) driven active matrix organic light emitting display (IR driven AMOLED) is formed by placing an IR activated OLED (IROLED) panel on an active matrix liquid crystal display (AMLCD) panel that has no color filters and has an IR backlight panel. The IROLEDs are up-conversion devices that convert the IR radiation transmitted through the IR driven AMOLED panel into visible light of a desired primary color.
Abstract:
Tungsten trioxide (WO3) nanoparticles are synthesized via a sol-gel route using metallic tungsten as precursor and printed on a flexible electrode using inkjet printing in order to build solid-state electrochromic cells. A method for separate control of different spectral regions of the electrochromic device (near infrared and visible) is disclosed.
Abstract:
A display device uses a multilayer film (104), which reflects (red) light having wavelenghts between about 600 and 800 nm at a 60 degree angle of incidence (114), to protect a liquid christal panel (102) from heat and sun damage. The film (104) transmits light of the visible band with a wavelength between about 420 and 650 nm at normal incidence (116). The outermost surface (106) of the film (104) may be a hard coat (124). A metal oxide layer (120) and a metal layer (130) may be included to reflect IR light greater in wavelength than about 850 nm.
