The device uses PPDS^® (Point-to-Point Differential Signaling) display technology licensed from National Semiconductor to dramatically simplify the LCD intra-panel interconnect and to reduce the total number of column-driver signals required, aiding manufacturers by enabling a physically smaller bezel around the TV screen while providing cinema-quality display performance. The use of this technology in the new LCD driver complements ST’s long experience and expertise in display systems and technologies, including computer monitors, TV applications, mobile displays, plasma screens, small-size LCD and OLED (Organic LED) displays.

“We have been working very closely with ST’s Asia-Pacific Design Center in the design-in of this innovative new LCD-driver IC,” said Mr.Wei Chun An, TV-R&D Director of CPT. “ST is already an important player in the display market and we believe this new family of LCD drivers will make a significant contribution to our mission to deliver world-class displays and further accelerate the use of large-size LCDs in consumer products.”

The STD8420x is being produced in a leading-edge process technology, developed by ST specifically for this application. Other products in the new family will also be designed in ST’s APDC in Singapore. Key features of the STD8420C include: 414/420 outputs, PPDS interface compatible, support for independent digital gamma control of each RGB color,  support for Dot and N-line inversion drive schemes, operation over a wide output voltage range, and 1024 gray levels per output built from internal 12-bit linear digital-to-analog converters. The STD8420A incorporates all the features of the STD8420C with the exception of output gray levels, which are limited to 256 steps.

ST is setting up a complete business unit in Singapore for LCD drivers to establish a fully integrated presence at the centre of major LCD-panel production. This unit provides a total value chain including design, product engineering, field application support and marketing services, assisting manufacturers in meeting their customers’ expectations for performance, TV set appearance and economy. Additionally, the chip design resources of the Asia-Pacific Design Center in Singapore have increased four-fold in the last five years, enabling the design of this innovative and cost-effective LCD column driver close to major flat-panel TV manufacturers to minimize time-to-market.

“These first large-size LCD source-driver ICs are clearly an important milestone in the company’s strategy to become a major player in the mainstream high-end LCD TV market,” said Philippe Berger, General Manager of ST’s Display Division. “The company plans to offer extremely competitive driver products based around the PPDS display architecture and implemented in our leading-edge process technology developed specially for the application, together with dedicated design and display driver support resources located close to the key fast-growing markets in Asia.”

Engineering samples of the STD8420C and STD8420A are already shipping to key customers. Pricing for the new ICs is in the range of $3 to $4.

Further information on ST’s Asia-Pacific Design Center (APDC)
The Asia-Pacific Design Center in Singapore was set up more than 20 years ago, in 1984 – the first such facility to be established in Singapore – to complement ST’s strong manufacturing presence in the region. Its advanced development capabilities, with core competency in analog and mixed-signal IC design, spearheaded ST’s penetration into the intensely competitive Asia-Pacific consumer and PC peripherals market. The APDC now participates in IC design for consumer, computer peripheral, smart card and imaging products, for ST’s globally-based customers. Revenues generated from locally designed devices have tripled over the last 5 years and its success has spawned a second Asia-Pacific based design center, in Seoul, Korea. Both centers are satellite-linked to other ST design facilities around the world, giving them access to the latest and most advanced design rules available in the company.
