At the same time, Freescale has been working with Eink to bring out the highest resolution and contrast while
reducing the ghosting effects and improving on page refresh times.
Some competitors, including Kobo, have made efforts to
reduce the amount of flashing the screen does to clear e-ink's slight
ghosting effect as you turn pages.
In comparison to the PSP - 2000, the PSP - 3000 (marketed in PAL areas as «PSP Slim & Lite (with enhanced screen + built in microphone)» and still marketed as PSP in North America and Japan) has an improved LCD screen with an increased color range, five times the contrast ratio, half the pixel response time to
reduce ghosting and blurring
effects, a new sub-pixel structure, a microphone, a new disc tray design, new button designs and logos, and anti-reflective technology to improve outdoor playability.
