N2 - Purpose: Our purpose was to compare the viewing angle performance on high‐brightness color liquid‐crystal display (LCD) monitors to that of monochrome LCD monitors. Method and Materials: We used four LCD monitors with an in‐plane switching (IPS) panel: two high‐brightness color LCD unt il 300 cd/m2, two‐megapixel, Eizo), and RX210, 220, cd/m2, two‐megapixel, Eizo), and two monochrome LCD monitors, (GS220, 500 cd/m2, two‐megapixel, Eizo, and G31‐S, 450 cd/m2, three‐megapixel, Eizo). The luminance performance of each LCD monitor was measured as a function of the viewing angle (−60° to +60°) in the horizontal, the vertical, and the diagonal directions by use of a telescopic‐type luminance meter without any ambient lighting. The viewing angle performance was evaluated with a relative contrast ratio of 70 % or greater. Results: The range of viewing angle in terms of relative contrast ratio on the 300 cd/m2 high‐brightness color, the 240 cd/m2 high‐brightness color, the 500 cd/m2 two‐megapixel monochrome, and the 450 cd/m2 three‐megapixel monochrome LCD monitors with similar IPS panels were 34° to 74°, 29° to 48°, 55° to 81°, and 39° to 74°, respectively. The relative contrast ratios showed notable variations for different viewing angles in spite of similar types of panels. Our results indicate that the viewing angle performance on the 240 cd/m2 color LCD monitor tended to provide a slightly inferior angular performance to the two monochrome LCD monitors used in this study. On the other hand, the 300 cd/m2 color LCD monitor had a comparable viewing angle performance with the 450 cd/m2 monochrome LCD monitor. Conclusion: The viewing angle performance on the high‐brightness color LCD monitors is inferior to that of monochrome LCD monitors. However the 300 cd/m2 color LCD monitor had comparable viewing angle performance with the 450 cd/m2 monochrome LCD monitor.
