Comparison Of Video Wall Technologies
| Super Narrow Bezel LCD | Rear Projection Cubes | HiRes Direct LED | |||
|---|---|---|---|---|---|
| Strength | Weakness | Strength | Weakness | Strength | Weakness |
| Low Cost of Ownership | Seams Creating Puzzling Effect | Long term Serviceability (upto 10 Years) & Upgradability | Real Estate – High Installation Depth | No Seams | Cost |
| Easy to Install (light weighted) |
Limited Serviceability (3-5 Years) | Reliability (Redundancy Level) & Long Term Stability (Screen Robustness) | Installability – Complex Installation | Higher Contrast Values | Dead Pixel Occurrence during Install and Operation |
| Real Estate – Low Installation Depth | Long Term Lack of Uniformity & Light leakage | Small Seams (Nogap Screens) | Poor Viewing Angles (Brightness) Impacting Wall Uniformily | Real Estate – Low Installation Depth | Complex Installation (esp. Mechanical) |
| Small Pixel Size (Closeby Viewing Experience) | Black Level/Contrast at Low Ambient (Local Dimming but Halo Effects) | Screen Option to Tune Verses the Application | Focus & Sharpness (Blurred) | Initial Full Wall Uniformily (Straight View) | Complex Maintainence (Mechanical and Optical Callibration, Binned Spare Parts) |
| High Quality, Interactive Touch Option Available | Image Retention and Burn in with Static Content | Low Black Level Variation | Distortion within 1 Cube (Geometry Adjustment) | High Brightness | Viewing distance : Pixel-to-Pixel Pitch & Fill Factor |
| No Specular Image Noise | Less Inter-tile Uniformily Calibration Options (No Primary Color Adjustments) | Low Power Consumption | Image Ghosting | Odd & Curved shapes | Large Variation in Black Levels (brownish) |
| Limited Color Gamut | Straight View Image Quality (e.g. Color Gamut) | Horizontal Viewing Angles | Poor Vertical Viewing Angle (Color Shift) | ||
| Specular Ambient Light Reflections | Power Consumption/heat managementt | ||||
