中文摘要：

利用现场可编程门阵列结合液晶显示器（LCD）的驱动芯片研制了一个17.8cm（7in）彩色AMOLED显示模块。用Verilog硬件描述语言编写了显示驱动控制程序。通过对OLED显示屏的研究,选择了适合该显示屏的LCD驱动芯片。通过研究LCD驱动芯片的特性,结合驱动OLED的实际需求,提出了一种屏幕与IC的连接方案。采用奇偶列像素数据线交错排列、列驱动IC并行工作的方法,克服了LCD驱动芯片点反转导致屏幕亮度损失一半的问题。针对数据驱动IC只能接收6bit/pixel的数据,而丢失了2bit数据的问题,文章在图像处理中引入了数字半调技术,利用Bayer抖动法对输入数据进行处理,提高了输出图像的质量。

英文摘要：

A display driving module based on the Field Programmable Gate Array（FPGA） with LCD driver ICs was designed by the research of the 17.8 cm（7 in） AMOLED.The program is designed with Verilog HDL.By studying the characteristics of OLED display,the LCD driver ICs is chosen to fit it.A method connecting screen with ICs is present.Through using double data-driver and changing the polarity of the ICs,the problem that dot inversion of LCD Driver ICs is not matching AMOLED is resolved,and the brightness is doubled.For the data driver IC can only receive 6 bit/pixel data,but lost 2 bit data,this paper introduced the digital halftone technique.Using dynamic Bayer dithering algorithm on the low 2-bit input data to compare,and the treatment results is fed back to the high 6-bit data.Thus the output image quality is improved.
