The Difference Between Thin-bezel LCD & Rear-projection DLP

Are you looking for an effective way to display information to your team members? Our display wall systems are the solution. It will allow every member of your team to monitor critical information from various sources and assets (data, graphics, environment, etc.) and respond to operational emergency situations simultaneously. When you’re deciding the display system that works best for your company, you should be considering the following:

  • Return on Investment (ROI)emergency control room, control room, display wall, video display
  • Smallest seams, or screen-to-screen gap
  • Need for 24X7 operation
  • Minimal downtime and high reliability
  • Life expectancy with the ability to upgrade the systems when available

The most commonly used control room display walls are the Thin-bezel LCD display wall systems and Rear-projection DLP display wall systems. Here are details about each along with a side-by-side comparison to help in making your decision.

Thin-bezel LCD

The Thin-bezel LCD (liquid crystal display) was introduced in 2010 and has since become increasingly popular in organizations where static data and graphics are shared, and space and budget are limited. Security operations centers have found this system to be particularly beneficial with multiple camera images arranged so the seams (as much as 5.7mm) within the screens do not distort the image. Although it is not used in a true 24/7 operation, it can be used up to 20 hours/day without significant effect on the image quality.

Rear-projection DLP

Also introduced in 2010, the Rear-projection DLP (digital light processing) was created to replace UHP lamps that needed annual replacement and required more power. This system has a 60,000-130,000 hour life expectancy on the LED light source and requires less power. Mission-critical organizations, like transportation, utilities or emergency management, find this system to be effective for sharing a variable information with a clear image (minimal seams). And it can be used 24/7/365 use with no effect on image quality.


Side-By-Side Comparison

Overall, the Rear-projection DLP’s ROI for maintenance and quality is much higher than that of the Thin-bezel LCD. However, the initial costs of deployment of the Rear-projection along with the space required make the Thin-bezel more appealing.
