摘要： A display assembly with dielectric filters is presented herein. The display assembly includes a light source assembly, a dielectric filter array, and a modulation layer. The light source assembly generates laser light in multiple color channels, and each color channel is associated with a different laser emission spectrum. The dielectric filter array includes respective sets of reflective dielectric filters for each color channel. Each set of reflective dielectric filters is matched to the different laser emission spectrum such that reflective dielectric filters in each set transmit light in the different laser emission spectrum and reflect light outside of the different laser emission spectrum. The modulation layer is positioned between a first electrode layer patterned on the dielectric filter array and a second electrode layer. The modulation layer modulates light from the dielectric filter array based on emission instructions applied via the first and second electrode layers to form an image.

摘要： A head up display (HUD) with improved resistance to sunload for use in a vehicle comprising an image generating device, an LCD assembly, an optical bonding assembly, and a fold mirror, with specific design countermeasures to combat damage caused to an LCD by heat from sunlight. These include an OB glass and cold mirror film (CMF) as components of the optical bonding assembly, a hot mirror coating and a polarized film as components of the LCD assembly, and a cold mirror coating on the fold mirror. When sunlight enters the HUD, the cold mirror coating reflects only visible light towards the LCD. The hot mirror coating reflects infrared and ultraviolet wavelengths of light away from the LCD. The polarized film cuts p-polarized light. The OB glass and CMF increase the specific heat of the HUD. The HUD thereby reduces sunload that would otherwise damage the LCD due to heat stress.

摘要： A display module including a display panel and an image color switch film is provided. The image color switch film is disposed above or below the display panel. In a viewing angle at least in a range of 45 degrees to 85 degrees, a peak of a transmittance spectrum of the image color switch film falls within a range of 400 nanometers (nm) to 600 nm, and an average transmittance of the transmittance spectrum within a range of 450 nm to 600 nm is greater than an average transmittance of the transmittance spectrum within a range of 650 nm to 800 nm.
