本文主要探讨210的LCD相关知识。
LCD LCD称液晶(透光+背光呈色),可在电信号驱动下使液晶分子旋转,呈现不同的颜色(被动发光)
lcd接口为TTL接口(+5V为1，0V为0),不能传输太远,远距离传输方式:SoC(TTL) ->VGA-> LCD(TTL)
其他显设备:CRT(阴极摄像管显示器),OLED,LED
RGB接口:VD0~23 24根数据线,HSYNC水平同步信号,VSYNC垂直同步信号,VCLK像素时钟,VDEN数据有效标志,LEND行结束标志
lcd显示
像素是组成图像的最基本元素(最小单位),扫描频率为刷新率
LCD显示单位为帧(一画面),一帧为多行,一行为多像素(像素矩阵)
LCD控制器通过数字接口给LCD驱动器提供数字信号
LCD驱动器给面板提供模拟电信号
显存是LCD控制器读取像素数据传输给LCD驱动器的区域
像素间距（pitch）是连续2个像素中心距离
分辨率（resolution）:屏幕的横纵像素个数就叫分辨率(210是800×480)
像素深度（bpp）:计算机用二进制位来表示像素的数据,位越多像素颜色值越多(1、8、16、24、32位)
24位：24二进制位表示颜色可表示16777216种颜色(RGB888分布)
210LCD控制器叫FIMD与AHB总线连接,对外部提供RGB接口、I80接口、YUV接口
210LCD控制器有5个虚拟屏幕Window0~Window4
HSPW水平同步信号脉宽
HBPD水平同步信号前肩
HFPD水平同步信号后肩
VSPW垂直同步信号脉宽
VBPD垂直同步信号前肩
VFPD垂直同步信号后肩
一行像素数据显示(LCD兼容):LCD控制器发送HSYNC高电平脉冲（宽度为HSPW）,HBPD+有效行信息+HFPD(三部分)或HSPW+HBPD+有效行信息+HFPD(四部分)
一帧帧图像显示(LCD兼容)：VSPW(帧同步信号宽度)+VBPD+帧有效信号+VFPD
210的LCD时序参数
h_fp = 210
h_bp = 38
h_sw = 10
v_fp = 22
v_fpe = 1
v_bp = 18
v_bpe = 1
v_sw = 7
210lcd寄存器
gpio
GPF0CON~GPF3CON(配置lcd功能)
