    Specifications

01

Light source segmentation (5th generation LED / 6xRedundant for R,G,B LEDs)

  • Separate configuration of laser light source into 8 independent laser elements each

  • Display configuration with appropriate colors by synchronizing the light number of normal modules based on the lost light amount of the failed module

  • Minimize maintenance costs by partial replacement of failed elements

02

Color & Bright Adjustment Calibration

  • 1×Laser adjusts color, brightness, etc. of the displayed image with dedicated S/W

  • 3×Laser provides preset (save and import) function

  • 3×Laser minimizes maintenance cost and time through easy adjustment function

03

Screen Spacing : 0.2㎜ (Option : Seamless)

  • Minimizes information loss by implementing 0.2㎜ screen gap optimized for multi-screen (Option: Seamless 0㎜)

  • Minimizes deformation of the screen due to temperature/humidity by special process

  • Various screen options : Black Bead, UCS, CSI, Seamless

04

Geometric Coordinates Correction

  • Free pattern adjustment of screen transmission image by fine adjustment of pixel by pixel without physical screen adjustment component, hexagonal adjuster

  • Prevents image distortion by vertical/horizontal adjustment of specific coordinates, image rotation adjustment, and realizes image gap of 0.05㎜ or less

05

Earthquake-resistant certified base (Option)

  • Base system that is certified for earthquake resistance as part of the situation room's seismic countermeasures

  • Can withstand earthquakes with a magnitude of 7~10 or higher (2012 Guidelines for Seismic Countermeasures for Power and Communication Facilities, etc. issued by the National Fire Agency)

06

Dual Power System

  • Redundant power supply to the engine module prevents equipment operation interruption due to failure and supports stable power supply

  • Hot swap replacement method [supports uninterrupted maintenance]

07

Other functions

  • Multi PIP with PIP Color Adjustment

  • Video Auto Gain Control (with 3D comb)

  • S/W Based Calibration Control and State Monitoring

  • Video Wall function

  • Video Scaler function

  • Rear LCD Panel (Power Control and State Monitoring)
