Portable Displays
The next attempt at a flat panel was with the Macintosh Portable. More of a desktop than laptop, it had a built-in high-resolution, active-matrix, 1-bit black & white, 9.8" LCD display with 640x400 resolution. Like the IIc Flat Panel, it was not backlit and required a bright light source to be used. A second generation model rectified that situation. Commencing with the PowerBook series, built-in LCD flat-panels became standard across the portable line, following an industry-wide evolution from grayscale to color and ranging from 9" to 17". Two primary technologies were used, active matrix (higher quality and more expensive) and passive matrix displays (lower quality and cheaper). By 1998 all laptops would use the standard active-matrix color LCD with a standard average dimension of 13", except for the Newton products and eMate portables. Apple's current MacBook portable displays include LED backlighting and support between 1280×800 to 1920×1200 pixel resolution. The iPhone 4 and iPod Touch 4's "Retina Display" has the lowest dot pitch of any Apple display, being 960×640 and only 3.5 inches.
