MagnaChip Accelerates Advancement into Smart Phone Driver IC Market

The leading provider of analog and mixed signal semiconductor products, unveils a full scale to advance
the market of display driver chips for smart phones. They started allocating driver IC for smart phones to a Korean-based major ‘A’ mobile phone maker earlier this year.
smart phone equipped with MagnaChip’s AMOLED driver chip was been recognized as an excellent product optimized for functions and capabilities of smart phones.

MagnaChip’s display driver chip for smart phones supports 16 million colors with WVGA resolution and uses the next generation technology of automatic current limit (ACL) and MIPI display serial interface (DSI), which are a good match for smart phones.
As for the vice president of MagnaChip, Hwang Tae-Young that MagnaChip intends to improve its driver chip technology and grow its market power by making a timely supply of high-quality products that are differentiated from the products of its rivals.
and early on, smart phone market is forecast to make a rapid growth of 46 percent per year by 2012.

MagnaChip Semiconductor announces WVGA resolution supported AMOLED driver chip – EA8850

A company from Korea called MagnaChip Semiconductor has just announced the EA8850, a new high-end WVGA resolution supported AMOLED driver chip that would give way to more high resolution handsets in the mobile market.

The EA8850 supports WVGA (480RGB x 864) resolution, and at the same time it also works with nHD (360RGB x 640) resolutions. It also supports Qualcomm’s Mobile display digital interface (MDDI) 1.2 technology.

Other features that you might take for granted about the MagnaChip Semiconductor EA8850: support for 16 million colors, automatic brightness control and smart mobile current control.

It wasn’t specified when the Korean company plans to supply this AMOLED driver chip to handset makers, but it should be present in devices that are to be released later this year.

TFT LCD Driver integrates MIPI and DSI on one chip.

August 12, 2008 - Suited for use in mobile phone displays, TA8560 combines MIPI (Mobile Industry Processor Interface) and DSI (Display Serial Interface) onto one driver chip. DSI, based on scalable serial interconnect, provides lower power modes and allows bi-directional communications. It supports 16-, 18-, and 24-bit pixels, buffered and un-buffered display panels, and QVGA (240 x 320) resolution. Chip can drive up to 4 panels from 1 interface and displays up to 16 million colors.

MDDI (Mobile Display Digital Interface) is Qualcomm's technology for high-speed serial interface between their MSM (baseband) chip and the peripheral including display module and camera module.

In 2006, I leaded the development of MDDI IP (Intellectual Property) including analog PHY and logic core.
The IP is successfully evaluated to 300Mbps for a data lane and supports dual display.
I designed my own MDDI logic core that receives 4-bit wise parallelized data and extract packets containing commands and display pixel data and transfer it to various legacy interfaces for the straightforward integration.
It requires only 30% area of Qualcomm's original MDDI core nonetheless it has the almost the same features.

Working with Qualcomm people was good experience and I still working on MDDI 1.2 with them.

블로그를 다시 시작할 수 있게 가장 큰 계기를 만들어 준 사람은 babyworm님이다.
학교에 있을 때 SystemIC 2010이라는 정부 프로젝트를 함께 한 분인데,
말이 함께이지 서로 소속과 과제가 달라서 이름도 모르고 직접 만난적도 없다. ^^;
하지만, 모두 국산 마이크로프로세서를 개발하는 것이 임무였기에 그 당시엔 서로에게 관심을 갖을 수 밖에 없는 상황이었을 듯...

babyworm님은 명령어부터 모두 순수 국산인 EISC라는 마이크로프로세서를 개발하였고, 난 그때(1999년)도 그렇지만 지금도 전 세계를 꽉 잡고 있는 ARM프로세서와 명령서가 호환되는 프로세세를 개발하였다. ARM7와 ARM9을 개발하여 RamP라는 휴대용 3차원 그래픽 프로세서에 탑재하였다. (아래사진은 ARM9을 탑재한 RamP-4)
