The iPhone 5’s Retina screen is the best smartphone display that DisplayMate has tested to date, according to results the firm posted today.

iPhone 5: “It is a significant improvement over the display in the iPhone 4,” said DisplayMate’s Raymond Soneira, who cited much lower screen reflections, much higher image contrast and screen readability in high ambient lighting — the latter, the highest he’s ever tested.

DisplayMate — which gave the display an “A” — also cited improved color gamut and factory calibration that “delivers very accurate colors and very good picture quality.” The Retina iPad is the only thing that beats it in accuracy, according to Soneira.
