SOLOMON SYSTECH LIMITED ANNOUNCES A NEW MEMBER OF
LCD DRIVER CONTROLLER CHIP WITH 
MULTI-LINE ADDRESSING (MLA) DRIVING SCHEME
FOR PORTABLE TELECOMMUNICATIONS AND CONSUMER APPLICATIONS

First of Its Kind to Drive 128x160 LCD Display with MLA in Single Chip

Hong Kong, Mar 30, 2001 - Solomon Systech Limited today announced a new member of LCD driver controller chip, part number SSD1854, for portable telecommunications and consumer applications such as cellular phones, PHS, and other portable consumer products like handheld game console and electronic organizer. The implementation of Multi-Line Addressing (MLA) driving scheme in single chip LCD driver controller is a pioneer in the market. Compared to the conventional single line addressing driving scheme, the MLA drives crisp clear display with better contrast, faster response and at lower power.

    Capable of driving 128x160 dot matrix, 4 level grey scale STN LCD, the SSD1854 integrates all common/segment driver outputs, voltage generator, internal regulator resistors, serial/parallel interface, selectable temperature compensation circuitry and oscillator in one chip to minimize the external components required in applications. By cascading two SSD1854, a maximum 256x160 display size can be supported. In addition, the device is designed to have all common output pins on one side to facilitate the latest packaging technology, Chip-On-Film (COF), for slim, light and compact system designs.

     The device adapts the most commonly used basic command set for easy programming. It has direct interface with the latest, fast DSP or MPU. Combining all the advanced features, Solomon Systech Limited makes SSD1854 a definite choice for the new generation portable telecommunication and consumer products.

Technical Specifications

     The SSD1854 is a 128x160 single chip graphic display LCD driver with MLA driving scheme. It is capable to display 16 characters by 20 lines alphanumeric character or 8 characters by 10 lines Kanji (16x16 dot) character. Operating in low voltage 1.8V to 3.0V, the IC provides on-chip 3x, 4x or 5x voltage generator for at most 17V high voltage output, which is good enough in the MLA featured display system. The on-chip "switch cap" divider improves the display quality while minimizes external components required.

    The device has a partial display mode where the LCD can be programmed to display with less number of rows at lower mux ratio. A standby mode can further help to reduce LCD power consumption by over 95%. The device provides selection on serial or parallel interface, which includes Motorola standard serial peripheral interface SPI, 8 bit 6800-series parallel interface and 8 bit 8080-series parallel interface. Advanced design in zero address setup / hold time enables the device to handshake with the latest, fast DSP or MPU protocol.

    Other features are LCD drive voltage temperature compensation at 8 selectable coefficients, 64 level internal contrast control, vertical scrolling, user programmable window scrolling, invert display and on-chip oscillator.

    The SSD1854 is manufactured in CMOS process, available in gold bump die. SSD1854 samples are available now at sample price US$6.0. For detailed information and product specifications, please contact Solomon Systech Limited or visit the web site at http://www.solomon-systech.com.
