Thorough Comparison Between iPhone 2G and 3G
Display performance was degraded. The display area of the iPhone 3G is composed of the chassis cover, the touch panel, the LCD panel and the proximity sensor (a). The chassis cover, the touch panel and the LCD panel are not integrated. In the iPhone 2G, the chassis cover, the LCD panel and the touch panel are bonded by resin (b, c). In this method, the display performance is enhanced because reflections of outside light and the backlight are reduced, compared with the method in which a layer of air is created between the LCD panel and the touch panel.
