iphone 4


This June will mark another milestone for Apple with its new iPhone4 release. iPhone4 claims use A4 processor developed by Intrinsity, which was acquired by Apple during April this year. You may remember that the A4 processor was used for iPad.

The phone will have ultra sharp display better than its predecessors, with two cameras, 960-by-640-pixel resolution at 326 ppi, and highest resolution for any handset display in the market! (All previous iphones have only 162ppi) Cool features include Video recording, HD (720p) up to 30 frames per second with audio, 5-megapixel still camera and VGA-quality photos and video at up to 30 frames per second with the front camera.

The touch sense

The phone will use Dual-Function Capacitive technology, Apple’s patent relates to displays having pixels that include capacitive elements, and more particularly to displays in which capacitive elements of the pixels that form part of the display system that generates an image on the display also form part of a touch sensing system that senses touch events on or near the display. So, higher the ppi, better will be the touch sense. With 960X640 and 800:1 contrast ratio touch would have to be highly precise.

A panel laminated on the glass senses your touch using electrical fields. It can register multiple touches at once to support advanced gestures such as pinch to zoom, two-finger tap, and more. The panel then transmits the information to the Retina display below it.
Capacitive sensors detect anything which is conductive or having dielectric properties.

The 3-axis gyro

This gives you angular velocity, allows pitch, roll and yaw. Also gives you rotation about gravity. Gyro and accelerometer enables you to sense 6-axis motions. Not to forget that, Apple patented gyro technology for the mouse back in February.
