AMOLED Touch Screens on 4G iPhones

Apple’s screen display and resolution has been getting a lot of attention. In comparison to the Android, Apple has retained similar screen resolutions for their iPhone and iPad products. This makes it easier for developers to create apps that will be functional regardless of the iPhone model.

According to Ming-Chi Kuo from the Digitimes publication, the support they get from their developers gives them an edge over their competitors. “If Apple changes the resolution for every new iPhone, it makes life extremely difficult for application developers since they would have to adjust the applications to ensure graphic quality,” Kuo stated during a recent interview.

The screen resolution may be improved but the ratio between the width and the length must be maintained to remain functional. Currently, the highest screen resolution on Android smartphone models is 854 x 480 pixels. For the iPhone 4G to be competitive, it must have 960 x 640 screen resolution, similar to the iPad. This “should be a plus for developers to create applications that fit both devices.”

Although there have been discussions between Samsung and Apple, will not be expected anytime soon. For one, Samsung is unable to supply the amount that Apple needs. There is a similar issue regarding Verizon and HTC on this matter. Samsung will only be able to provide up to 60% of what iPhone 4G needs, even if Apple decides to switch to using AMOLED screens. Another issue is the pricing. AMOLED screens cost a whopping US $34- $38.

The iPhone 4G will be using both IPS (in-plane switching) and FFS (fringe-field switch) panels, costing around US$10 and US$20 respectively. These technologies are more efficient in terms of battery consumption and offer a better viewing experience compared to the AMOLED. According to Kuo, if Apple wishes to provide e-reading features, “AMOLED may not be the best solution at the moment” as they are not appropriate for showing text.
