1. Introduction Apple, Inc. has released a new addition to their iPhone series- the iPhone 7. Among the many features of the new model, the one that has caught everyone's attention is its display quality. The iPhone's retina display with a resolution of 1334x750 pixels at 326 ppi has been upgraded with a 25% brighter screen than its predecessor. It features the same size 4.7" screen as the iPhone 6 but with many improvements. In this article, we shall examine the iPhone 7's display quality in detail. 2. Pixel Quality and Color Accuracy The pixel quality of any screen determines the clarity of images displayed on it. The iPhone 7 boasts an impressive pixel density of 326 ppi which is at par with other premium smartphones. However, pixel quality alone does not guarantee the quality of images displayed. The color accuracy also plays an equally important role. The iPhone 7's screen has been calibrated to produce colors that are pleasing to the eye and accurate as well. Apple claims the display is capable of displaying up to 25% more colors than its predecessor. The iPhone 7's display is not only vibrant but also true to life. 3. Contrast Ratio Contrast ratio is defined as the difference between the darkest and brightest images that a device can display. A high contrast ratio ensures that images appear crisp and clear irrespective of lighting conditions. The iPhone 7 has a contrast ratio of 1400:1 which is very impressive. This means the blacks are deep and the whites are bright, resulting in a display that stands out in any lighting condition. This high contrast ratio also ensures that users can easily read text on the screen, even in bright sunlight. 4. Conclusion The iPhone 7 has undoubtedly raised the bar when it comes to display quality. The pixel quality, color accuracy, and contrast ratio are all exceptional, and they all work together to create a display that is both pleasing to the eye and accurate. Apple's commitment to producing premium devices is evident in every aspect of the iPhone 7, and the display is no exception. The only drawback some users have experienced is an issue with screen burn-in. However, this is easily remedied by adjusting the display settings. Overall, the display quality of the iPhone 7 is truly impressive, and it sets a new standard for the industry.
