The study, by NPD, published Tuesday shows that the average size of mobile phone screens has shot up from 2.4 inches to 3 inches since 2010 (a projected 38 percent increase if the trend continues in 2013), and OLED TVS, portable media players and even public displays have all jumped in screen size by more than 10 percent over the same period. Even the average desktop monitor has gained nearly an inch since 2010. In fact, the only category of device where things seem to be running in reverse is mobile PCs --ie, notebooks and laptops, which will have shrunk by 10 percent to a projected average screen size of 12.2 inches by 2013.
This falling screen size could be due to manufacturers focusing more on ultrabooks but it is also likely to have been influenced by the growing competition from tablets. Notebook manufacturers are reducing their costs to compensate for lower sales and cutting the screen size is a good way of saving money.
And this trend looks set to continue. Therefore it won't be long before smartphones are as big as today's tablets, tablets are bigger than the average notebook and desktop monitors are the size of a widescreen TV.
