The iBook computer has a built-in color flat panel display. The display is backlit by a cold cathode fluorescent lamp (CCFL). The display uses TFT (thin-film transistor) technology for high contrast and fast response.
Two sizes of displays are available: 12.1 and 14.1 inches, measured diagonally. Both displays contain 1024 by 768 pixels (XGA display) and can show up to millions of colors.
The graphics controller IC is an ATI Rage Mobility M128. The graphics IC has 8 MB of video RAM on the chip. It supports 3D acceleration and display depths up to 24 bits per pixel. When more graphics storage is needed, the graphics IC can also use part of main memory. For more information, see "Graphics IC".
The graphics IC includes a scaling function that expands smaller-sized images to fill the screen. By means of the scaling function, the computer can show full-screen images at 1024 by 768, 800 by 600, or 640 by 480 pixels.
