LCD source driver speeds data at 500 Mb/s
Feb 7, 2006 5:10 PM 

Oki Electric Industry Co. Ltd. has announced the development of a 13-bit digital source driver for high-definition, liquid crystal display (LCD) systems. The MT3100 is the first to adopt Oki's high-speed image transferring method, FP-LVDS (flat panel low-voltage differential signaling), resulting in a data transfer speed of 500 Mb/s. It is suited for high-definition LCD monitors in medical and graphic applications in which complex color management is required. The company plans to promote its FP-LVDS technology to LCD module manufacturers, aiming to establish it as a defacto standard for high-speed interfaces.

The MT3100 provides 8200 gray-scale levels and its 13-bit resolution of gray-scale resolution is available at each output port, enabling it to individually control the characteristics of the RGB, resulting in a clearer and more natural image than with current controls.

Oki developed the FP-LVDS basing it on the commonly used mini-LVDS(2) method. It is compatible with the mini-LVDS and with a full HDTV display, thereby enabling it to handle the required 120 Hz frame rate. The FP-LVDS uses the "multidrop(3)" method, which has fewer limitations as to the number of output ports (channels), compared with the "point-to-point(4)" method that sends data individually from a timing controller. With this advance, Oki achieved simplification of system design and reduction of development costs and turnaround time.

Samples of the MT3100 will be available in March.

Founded in 1881, Oki Electric Industry Co., Ltd. was Japan's first telecommunications manufacturer; its headquarters are in Tokyo.
