Flat-Panel Display

The 12-inch PowerBook G4 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.

The display is 12.1 inches measured diagonally and displays 1024 x 768 pixels (XGA), showing up to millions of colors.

The graphics controller IC is an nVidia GeForce FX Go5200 with 64 MB of video DDR SDRAM 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.
