46" - 3,000 nits - DS46LO4

  • Description


The DS46LO4 is a 46 inch ultra high brightness LCD featuring 1080p HD resolution. With a maximum brightness rating of 3,000 cd/m² this display produces a sunlight readable image which may easily be seen in storefront windows and other brightly lit indoor environments. The DS46LO4 features a fanless, proprietary thermal management system and a unique local dimming LED backlit technique for incredible, high contrast picture quality.

Local Dimming

High Brightness LED Backlit With Local Dimming

LED back lighting 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 DS46LO4 utilizes a proprietary system of LED backlighting 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 back light 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.

Fanless Thermal Management

Fanless Thermal Management System

Heat dissipation is always a concern when dealing with LCD panels operating around the clock. To increase performance and prolong the lifespan of the display, DynaScan’s DS² High Brightness Series utilizes a proprietary Thermal Management System. Heat generated by the display is radiated away from high temperature areas while a sensor continuously monitors the internal temperature to protect the system from overheating. All of this is done without the use of any fans, resulting in silent operation and greatly reducing the potential of mechanical failure. This is especially beneficial in areas with a lot of dust which can eventually obstruct a vent and cause the display to overheat.

D65 Color Calibrated

Color Temperature and Quality

The DS46LO4 comes equipped to display both D55 (5500 K) and D65 (6500 K) CIE color standards right out of the box – a feature lacking from many of the large format commercial LCDs currently on the market. As many displays have a tendency to be rather cool or “bluish”, these color settings produce a very natural looking image which has a correlated color temperature to that of daylight.


Auto Brightness Control

Different external lighting conditions require different brightness levels. An onboard light sensor measures the ambient light in the area and automatically adjusts the image accordingly.


Full HD Resolution

With a resolution of 1920 x 1080 Full HD, the DS46LO4 provides a super sharp image for easy to read text and incredible detail.
