TOKYO The Japan Electronic Industry Development Association has approved the Digital Interface Standards for Monitor (DISM) as the JEIDA-59-1999 standard. DISM defines the connection among video boards in a personal computer and the monitor display.
The digital-interface standard includes four digital transmission formats: TMDS (transition-minimized differential signaling), LVDS (low-voltage differential signaling), LDI (LVDS Display Interface, proposed by National Semiconductor Corp.) and GVIF (Gigabit video interface).
The DISM working group started discussion under JEIDA's Display Technology Committee last April and announced preliminary specifications in November. Since then, a few changes have been made, such as lowering the number of connector pins for the LDI format from 40 to 36.
The last potential fix is a name change. The registered name DIZM already exists, so the working group will soon decide whether to alter the nomenclature of its digital-interface standard.
