Apple Watch Display Quality Judged 'Excellent', Calibrated to Match iPhone 6

DisplayMate Technologies has extensively tested the Apple Watch's flexible OLED display and shared the results today based on several categories, including screen reflection, brightness and contrast with ambient light, color gamut with ambient light, and viewing angle variations. Overall, the company found the Apple Watch to have an "excellent smart watch display" with accurate colors and picture quality.

In a side-by-side comparison with the iPhone 6 display, the display calibration company found that Apple has taken measures to ensure that the Apple Watch display has the same colors, color calibration and color accuracy as the larger smartphone screen. The stainless steel and gold Apple Watches with sapphire crystal displays, however, have much higher reflectance in ambient light and mandatory automatic brightness control to preserve battery life.

"Since the Apple Watch is often used right next to the iPhone 6, Apple has gone to considerable lengths to give them the same colors, color calibration, and color accuracy. The two most significant differences (other than size) are the much higher Reflectance of the Apple Watch with a sapphire crystal (8.2 percent compared to 4.6 percent), and the aggressive Brightness control using a mandatory Automatic Brightness Ambient Light Sensor in order to increase the running time on battery for the tiny watch."

The full-length report offers a comprehensive look at the Apple Watch's ion-strengthened and sapphire crystal displays, and reiterates that enhanced sapphire, which lowers the screen reflectance of sapphire to be much lower than glass, will soon be available for use in smartphones, smartwatches and other mobile devices. Additionally, DisplayMate's previous tests of the Samsung Gear 2 and Sony SmartWatch 2 displays provide good comparisons to the Apple Watch.
