摘要 该有机发光显示器驱动电路由一个384通道列驱动电路和一个160通道行驱动电路组成。列驱动电路是一个内置128×3×160×4bit显示数据存储器的128×3红绿蓝控制器,支持用户可编程4/8bit灰度控制,高精度的电流匹配电路和内建预充电路确保了均匀的亮度和高质量的灰度显示。驱动电路可通过8bit/16bit并行接口直接与微处理器相连,显示数据可以存储在内部,还可独立于微控制器产生有机发光显示器的驱动信号。行驱动电路有可选的电压预充电路和内建低接通电阻确保在高速扫描时的亮度均匀。该驱动电路是一个低功耗低输出阻抗的有机发光显示控制器。 The OLED driver consists of a 384-channel column driver and a 160-channel row driver. The column driver is a 128 × 3 RGB controller with 128 × 3 × 160 × 4 bits display data memory. It supports user programmable 4/8-bit gray scale. The high accurate current-matching and built-in pre-charge circuit ensures uniform luminance and high-quality gray scale. It can be directly connected to a microprocessor via 8-bit/16-bit parallel interface. The display data can be stored in the internal memory and the driver can generate an OLED driving signal independent of the microprocessor. The row driver ensures uniform luminance at rapid scan rates with the voltage pre-charge option and built-in low switch on resistance. This driver is a low power consumption and low output impedance OLED controller.
