PC magazine had an expert on LCD screen technology, Dr. Raymond Soneira, conduct tests on the top smart phone displays on the market in order to determine the “best screen”. The phones compared in the test: Apple iPhone 4, Motorola Droid X, HTC Droid Incredible and the HTC EVO. The metrics measured were: brightness, contrast, color depth, and color accuracy.
Out of these metrics, for radiology images, brightness and contrast are the two most important. In the brightness test the iPhone 4 won, but when it came to contrast ratio, the HTC Droid was hands down superior to the competitors.
This is due to the OLED (organic light emitting diode) display on the HTC Droid, enabling it to create extremely dark levels of blacks – although this isn’t good for viewing the display outside, it’s great for radiology image viewing when different levels of black are essential. Remember, the radiologists usually view their images in the dark.
Overall though, with all the metrics taken into account, the iPhone 4’s screen came out on top. Further showing why healthcare IT and radiology shouldn’t be afraid to embrace iPhone 4 specific medical imagining apps. The tests also showed the HTC Droid shouldn’t be forgotten as a potential medical imaging tool.
