The LDS312/314 products are highly-integrated,
high-performance devices that include on-chip DC-DC converter and an
adjustable VCOM generator. The devices integrate programmable display
features, such as color depth selection, frame inversion and N-line inversion
for low cross talk. In addition, the LDS312/314 have selectable gamma
correction support for optimized display performance.

They require special software called drivers to communicate with the operating system kernel .

Certain video cards are called accelerators in that their drivers are optimized to take special requests from the operating system and process them in much less time than a normal request would take .

About Leadis Technology, Inc . USA

When: March 1-3, 2005

At IDF, Rambus will showcase its high-speed chip interface
products, featuring demos and displays on:

Rambus's PCI Express(1) board running Agilent's latest PCI
Express electrical compliance tests;

Graphics, chipset, switch and bridge products that include
Rambus's PCI Express PHY interface;

Rambus's XDR(TM) memory interface solution, a differential
memory technology with data rates ranging from 3.

At any given resolution and color depth, there is a speed at which each vertical and horizontal screen can be drawn called refresh rate or frequency (measured in Hertz [Hz]).

Examples are windows accelerators which draw windows components quickly, 3D accelerators which render and display polygons at tremendous speeds.
