  2. Optimum HDTV viewing distance - Wikipedia

    en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

    The maximum viewing distance (minimum viewing angle) provided by Best Buy aligns with vision theory on the highest spatial frequencies perceivable by the human visual system. [41] Crutchfield's maximum viewing distance aligns with the lower boundaries where viewers typically begin to find HDTV immersive.

  3. Quantum dot display - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot_display

    A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...

  4. LED-backlit LCD - Wikipedia

    en.wikipedia.org/wiki/LED-backlit_LCD

    Edge-LED lighting for LCDs allows thinner housing; the Sony BRAVIA KLV-40ZX1M is 1 cm thick, and others are also extremely thin. [citation needed] LED-backlit LCDs have longer life and better energy efficiency than plasma and CCFL LCD TVs. [35] Unlike CCFL backlights, LEDs do not use mercury in their manufacture, which is an environmental ...

  6. ATSC standards - Wikipedia

    en.wikipedia.org/wiki/ATSC_standards

    The 1080-line system does not support progressive images at the highest frame rates of 50, 59.94 or 60 frames per second, because such technology was seen as too advanced at the time. The standard also requires 720-line video be progressive scan, since that provides better picture quality than interlaced scan at a given frame rate, and there ...

  7. Package cushioning - Wikipedia

    en.wikipedia.org/wiki/Package_cushioning

    If a product is on a large load-bearing area, the cushion may not deform and will not cushion the shock. If the load-bearing area is too small, the product may “bottom out” during a shock; the shock is not cushioned. Engineers use “cushion curves” to choose the best thickness and load-bearing area for a cushioning material.

    Diagram illustrating the flange focal length of an SLR–type and a mirrorless–type camera. For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus [1] or register, depending on the usage and source) of a lens mount system is the distance from the ...
