All ThingsD said the new tablet, which will probably be named iPad 3, will feature a 20481536 Retina Display or something close to it.
The iPhone 4 and iPhone 4S have Retina Display.
As the human eye can only see around 300 pixels per inch, the screen of these smartphones have 326 pixels per inch, making texts and images look more similar to a high quality printed version.
The report did not say when the iPad 3 will hit stores. It expected the device to follow the same schedule as that of the iPad 2, which was available for purchase about a week after the event.
Apple has declined to comment on the timing of the event.
