There have been rumors of Apple testing bigger display for its upcoming iPhone variants. Dimensions of 4.5 inch screen size undergoing tests by Apple for their iPhone device has been reported by WSJ. A similar bit of news comes from KGI Securities, Mingshi Kuo. That the screen size would not go beyond the 5 inch size is what the note from Mingshi Kuo indicates.
Apple has been sticking to the screen size which allows for one hand operation instead of going for larger screen sizes which makers like Samsung have adopted for quite some now. This would be contrary to what Steve Jobs believed that a 3.5 inch display makes for the best and most convenient size for a smartphone display. However, that could be too small for the enhanced role that smartphone devices are being applied to right now. The larger screen has its own charm and utility which Apple appears to be acknowledging now. As a midway point Apple is therefore keeping to the 5 inch screen size as the max which would yet allow for one hand operation. The current iPhone range comes with a 4 inch display.
Apple has also been linked to developing a big screen smartphone which will let the company have a competitor in the burgeoning phablet segment. So popular has the segment emerged to be that IDC is even predicting a decline in interest for 7 inch tablets thanks to a greater uptake of phablet devices. Samsung with its Galaxy Note 3 device might be the biggest player in the segment right now though the equation could change this year as others too have either joined the fray or are in the process of doing so. These include the HTC One Max, the Nokia Lumia 1520, Sony Xperia Z1 and so on.
The note from Kuo also indicates that while increasing the screen size Apple would keep their screen technology which is based on the in-cell touchscreen principle. Technology for the iPad however would be moved to the GF2 technology as per Kuo. This would enable Apple making a thinner and lighter tablet.
