Gray Scale OLED Driver

Single Chip 16 Gray Level of OLED Driver IC with Integrated Controller and build-in DC-DC voltage converter for Cellular Phone Application

Solomon Systech Limited is launching a new OLED driver with controller IC SSD1328.  It features 16 gray level control, built-in DC-DC voltage converter and supports maximum 128×128 matrix panel. Driven by Solomon Systech Limited own-patented OLED proprietary driving scheme, the SSD1328 enhances the performance of OLED display and reduces system power consumption.  Therefore, it is a perfect solution for low power handheld cellular phone application.


SSD1328 is a single-chip OLED driver with controller for monochrome passive OLED/PLED panel.  Thanks to 16 gray level control, images are displayed more attractively and the details of graphics can be unveiled.  Internal DC-DC voltage converter is designed to supply high voltage for OLED output and it saves the number of external components.  Thus the solution makes the end application like cellular phone smaller more compact and more competitive.


Selectable types of MCU interface are provided to send commands to control the functions of SSD1328 like contrast setting, column and row re-map, multiplex ratio, vertical scrolling and gray level control.


The wide range of software contrast control, from 0 to 300µA, and programmable multiplex ratio makes SSD1328 suitable for various kinds of Organic Light Emitting Diode display with different pixel size and color.  IC is now available in gold bump die and TAB package.
