The organic light emitting display driver circuit consists of a 384-channel column driver circuit and a 160-channel line driver circuit. The column driver circuit is a 128 × 3 red, green and blue controller with built-in 128 × 3 × 160 × 4bit display data memory, user-programmable 4 / 8bit grayscale control, high precision current matching circuit and built-in precharge circuit to ensure A uniform brightness and high quality grayscale display. The driver circuit can be directly connected to the microprocessor through the 8bit / 16bit parallel interface, the display data can be stored internally, and the drive signal of the organic light-emitting display can also be generated independently of the microcontroller. The line driver has an optional voltage precharge circuit and built-in low on-resistance to ensure even brightness at high-speed scanning. The driver circuit is a low power, low output impedance organic light emitting display controller.
