Displaychips Inc has launched an OLED driver chip (DC3100), which is said to integrate DC-DC converter for the first time in the world. The chip doesn't need an additional external DC-DC converter to drive the passive-matrix OLEDs, resulting in 10 to 15% cost reduction of the module assembly.
Based on a 0.20µm CMOS process, the chip adopts a low current consumption algorithm backed by a patented technology. The pre-charge technology is said to reduce power consumption to 50% of the established OLED driver ICs.
Internal DC-DC converter is 6 to 18V, and external power is 6 to 21V. Power supply for logic is 1.7 to 3.3V, and power supply for analog is 2.4 to 3.3V. OLED driver supply from booster or external is 5.0 to 18.0V. Adjustable frame frequency is 60 to 150 frames per second.
The OLED driver IC with 96 commons and 288 segments for 65,536 color driving stores the serial or parallel BIT data transferred by the MPU on the built-in RAM (147,456 bits for graphic) and generates the signals to drive an OLED panel.
