The DS381LT4 is a 38-inch high brightness stretched professional LCD. With a stretched 32:9 aspect ratio, the DS381ST4 is designed for special applications where height is limited. A brightness rating of 2,500 nits produces a daylight viewable image for high ambient light installations. A local dimming backlight provides incredible, high contrast picture quality and low power consumption.<br>LED backlighting is both more energy efficient and provides a much brighter image than traditional CCFL backlights. Due to the compact nature of LEDs, displays are also typically thinner. The DS381LT4 utilizes a direct LED backlighting system which is not only more energy efficient than traditional CCFL backlights, it is also considerably brighter. DynaScan has applied its LED expertise to create a collection of ultra-high brightness LCDs which can easily be viewed in direct sunlight such as storefront windows or outdoor enclosures. The display features a local dimming LED backlight technique for a remarkably high contrast picture as high as 1,000,000:1 (dynamic). With direct local dimming, darker areas of an image receive less backlighting than lighter areas, as opposed to CCFL and edge-lit LED backlights which illuminate an entire screen at all times causing blacks and dark areas to appear washed out.
