LCD driver chip using MDDI technology can shift data from parallel to serial between the mobile phone modem and LCD panel.

MagnaChip Semiconductor has brought out an LCD driver chip using MDDI technology pioneered by Qualcomm.

MagnaChip chose to incorporate MDDI (Mobile Display Digital Interface) technology, a VESA Standard interface, into its driver chip because MDDI can shift data from parallel to serial between the mobile phone modem and LCD panel.

MDDI also allows for high-speed transmission of large volumes of data to LCD panels and high-resolution camera phones.

Using MDDI, MagnaChip developed the WQVGA(x) LCD driver chip, which can transmit data at a maximum of 220Mbit/s.

Additionally, MagnaChip reduced the number of circuit lines connecting the modem and LCD panel from forty to seven.

The reduced circuit lines provide a substantial contribution to cost savings, as well as design flexibility for LCD module makers.

Davis Mok, Vice President of Marketing in MagnaChip's Display Solutions Division, says: "This product supports high speed serial interface, and it is a perfect fit for HSDPA mobile phones and next generation high speed mobile phones".

"Qualcomm's MDDI technology enables stable transmission of large volumes of data at high speed with low power consumption".

"We look forward to maintaining a collaborative relationship with Qualcomm to support our continued technological advancement and business expansion in mobile phones".

MagnaChip will continue to develop LCD driver chips with MDDI technology and specifically expects to launch additional products in the second half of 2007.
