摘要
针对多线寻址驱动方案,以驱动算法的数学理论为基础,建立了可由EDA工具综合的硬件驱动算法模型。该算法模型综合了FRC-PWM灰度技术的解决方案,通过FPGA验证,实现了在保证CSTN-LCD显示效果的前提下使电路设计达到最优化。
For the lower cost and power consumption, STN-LCD has been widely used in low and mid-end mobile applications. Based on the mathematical description, a multiple line addressing scheme is approved. We built a mathematical model that can be synthesized by EDA tools for hardware. Combined with the FRC-PWM solution of grey shading, the model is validated by FPGA. As a result, the circuit is optimized for guaranteeing the display quality of CSTN-LCD.
