(整理)普通51单片机驱动35寸TFT的应用实例与源代码
普通51单片机驱动3.5寸TFT的应用实例与源代码！发布: 2010-1-15 16:59 | 作者: pcb_dz | 来源: 网络 | 查看: 675次前市场流行的3.5寸屏基本上都是只内置了驱动器，而不带控制器，这样给用户的使用造成了一些难度。
基本上很多朋友在用彩屏时选择一些带LCD控制器的ARM7或ARM9去开发，对于不会ARM开发的朋友来说，只使用普通MCU，这样可以选择的3.5寸TFT模块，就很难找到了。
本文就是基于市场上一款比较使用的3.5寸TFT模块编写的，用户只需要帮该TFT模块当作普通的单色液晶的开发思路来使用，就可以很容易去编程。
一、硬件选择1、 MCU：AT89S512、开发编译环境：Keil C513、 3.5寸TFT模块型号：MzT35C1二、TFT模块基本性能：1、基本参数模块结构：内置控制器屏幕大小： 3.5英寸屏幕分辩率：320*240屏幕颜色数：65536色（16位真彩色）工作电压： 3.3V/5V可选总线结构： Intel8080总线宽度： 8Bit背光形式：LED；可指令控制，0-127可调连接方式：排针插座触摸屏：标准配置不带触摸屏；模组留有触摸屏芯片焊盘和触摸屏接口2、接口引脚说明3、操作时序（8位并行Intel 8080总线）MzT35C1模块支持intel8080总线，总线的最高速度可达20MHz（当然总线的速度能否达到最高接口速度，还与用户的总线布线、线长等有关），也就是说，如果控制MCU速度足够快的话，是可以支持视频的显示的。
注意：MzT35C1模块的总线接口是8位的，也就意味着对显存的数据操作时，需要连续进行两次操作方可完成，先传高字节再传低字节；但对于寄存器的操作（写入寄存器地址，即A0为低时的写入操作）8位的操作方可。
三、MzT35C1与51硬件接口连接图本例程使用GPIO来模拟总线时序。
上图的模块供电为5V的模块，而模块的端口电平为3.3V的，所以在所有的51端口与模块间的连接串入了一个100欧的电阻，有关MCS51的其它电路不在图中画出，请用户具体参考其它的开发板文档进行了解。

Note on handling(1) Static charge prevention Be sure to take the following protective measures. TFT-LCD panels are easily damaged by static charges. A) Use non-chargeable gloves, or simply use bare hands. B) Use an earth-band when handling. C) Do not touch any electrodes of a panel. D) Wear non-chargeable clothes and conductive shoes. E) Install grounded conductive mats on the working floor and working table. F) Keep panels away from any charged materials. G) Use ionized air to discharge the panels. (2) Protection from dust and dirt A) Operate in a clean environment. B) Do not touch the front light surface. The surface is easily scratched . C) Use ionized air to blow dust off the panel.(3) Other handling precautions A) Do not twist or bend the flexible PC board especially at the connection region because the board is easily deformed. B) Do not drop the module. C) Do not twist or bend the module. D) Keep the module away from heat sources. E) Do not dampen the module with water or other solvents. F) Avoid storage or using the module at high temperatures or high humidity , as this may result in damage.HT CCo34nfide nti a。

1. PANEL 成像原理
LCD(Liquid Crystal Display)液晶显示屏使用了目前最新旳全彩 显示技术。
4、观察屏幕视角：是指操作员能够从不同旳方向清楚地观察屏幕 上全部内容旳角度，这与LCD是双层超扭曲向列(Double Super Twist Nematic)还是薄膜式晶体管(Thin Film Transister)有很大关系。因为 前者是靠屏幕两边旳晶体管扫描屏幕发光，后者是靠本身每个像素背 面旳晶体管发光，其对比度和亮度旳差别，决定了它们观察屏幕旳视 角有较大区别。DSTN－LCD一般只有60度，TFT－LCD则有160度。
显示屏有M条信号电 极母线和N条扫描电 极母线。

PANEL技术缺陷
PANEL克服了CRT体积庞大、耗电和闪烁旳缺陷，但也同步带来了造价 过高、视角不广以及彩色显示不理想等问题。CRT显示可选择一系列辨别率， 而且能按屏幕要求加以调整，但PANEL只具有固定数量旳液晶单元，只能在 全屏幕使用一种辨别率显示(每个单元就是一种像素)。CRT一般有三个电子 枪，射出旳电子流必须精确汇集，不然就得不到清楚旳图像显示。但PANEL 不存在聚焦问题，因为每个液晶单元都是单独开关旳。这正是一样一幅图在 PANEL屏幕上为何如此清楚旳原因。PANEL也不必关心刷新频率和闪烁，液 晶单元要么开，要么关，所以在40-60Hz这么旳低刷新频率下显示旳图像不 会比75Hz下显示旳图像更闪烁。

TFT 测试辅助电路
TFT 面板的 Gate、Vdata、Vcom 电压通过线路直接和驱动 IC 连 接，是 PIN-PIN 的对应连接，但是在测试时，如果要实现每个电极和 测试驱动单元的连接，则需要高密度的 PROBE-CARD 连接，测试成 本高到无法接受。那如何才能实现在没有连接驱动器的状态下，快速 判断 TFT 显示器的品质呢？于是，设计了以下测试辅助电路： TFT 电路结构示意图：
图 5. TFT 测试辅助电路示意图
TFT 制造商在面板显示电路以外设计了测试辅助电路。例如：将 所有的 VR 信号端通过一个场效应管连接后，并在一起形成一个测试 电极 VR ，这些场效应管在截至状态下，TFT 显示器处于正常工作 模式，每个数据端分别于 IC 对应的信号端连接。当显示器要进行测 试时，将所有测试场效应管的栅极施加 VGG 电压，这个电压一定要

公共电极驱动方式
为了达到极性不停变换的目的，我们通常采用两种方法来实现： 1.公共电极电压固定不变，只变换显示电压；

TFT LCD使用心得最近一段时间工作上一直在使用TFT LCD，主要是 3.5寸LCD，以SAMSUNG的LTV350QV及其一些台湾的兼容产品为主。
工作的内容就是把这些屏在我们的产品上应用起来，经过这一段时间后，发觉对TFT LCD的内部结构还是不怎么清楚，所以最近几天花了一些时间了解TFT LCD的结构以及工作原理，并整理下来加深自己的理解以及提供大家参考，这只是我自己的一些理解，错误的地方请大家多指正。
首先，我们了解一些TFT LCD的结构，如下图所示，主要由偏振片、虑色器基板、液晶、TFT基板、片振片、背光源组成。
在虑色器基板和TFT基板封入扭曲向列型液晶（TN），构成液晶盒，虑色器基板上制作有透明的公共电极，TFT基板上制作了矩阵式薄模晶体管，用来开光象素电极的电压信号，为了使液晶层保持一定的厚度，在两块玻璃基板中间放有透明隔垫（聚酯模片或玻璃小球）。
TFT LCD电信号部件组成：主要由背光电路和显示电路组成。
背光电路： 3.5寸TFT LCD背光，大都采用白光LED作为背光源，一般由6个串连的白光LED组成（如下图），驱动电压大概20V左右，20mA电流左右，是一个耗电量很大的部件。
对于电池供电系统，大都采用升压型DC/DC进行驱动，很多厂家都有推出专门针对串连白光LED的驱动器。
显示电路：显示电路一般由Timing Controller、Source Driver、Gate Driver组成。
有的IC 把Timing Controller和Source Driver集成在一起了，也有的IC把三个部分都集成了。
这三部分电路一般都集成在TFT LCD模组里面了，也有的TFT LCD把Timing Controller IC放到外面了（如SHARP的一些LCD）。
SAMSUNG LTV350QV LCD框图分析（如下图）：LTV350QV的DRIVER IC是S6F2002，S6F2002集成了Timing Controller、Source Driver、Gate Driver部分和电源管理部分，164RGB X 240驱动能力，所以对于320 X 240 QVGA的分辨率，需要两片S6F2002。

普通51单片机驱动3.5寸TFT的应用实例与源代码！发布: 2010-1-15 16:59 | 作者: pcb_dz | 来源: 网络 | 查看: 675次前市场流行的3.5寸屏基本上都是只内置了驱动器，而不带控制器，这样给用户的使用造成了一些难度。
基本上很多朋友在用彩屏时选择一些带LCD控制器的ARM7或ARM9去开发，对于不会ARM开发的朋友来说，只使用普通MCU，这样可以选择的3.5寸TFT模块，就很难找到了。
本文就是基于市场上一款比较使用的3.5寸TFT模块编写的，用户只需要帮该TFT模块当作普通的单色液晶的开发思路来使用，就可以很容易去编程。
一、硬件选择1、 MCU：AT89S512、开发编译环境：Keil C513、 3.5寸TFT模块型号：MzT35C1二、TFT模块基本性能：1、基本参数模块结构：内置控制器屏幕大小： 3.5英寸屏幕分辩率：320*240屏幕颜色数：65536色（16位真彩色）工作电压： 3.3V/5V可选总线结构： Intel8080总线宽度： 8Bit背光形式：LED；可指令控制，0-127可调连接方式：排针插座触摸屏：标准配置不带触摸屏；模组留有触摸屏芯片焊盘和触摸屏接口2、接口引脚说明3、操作时序（8位并行Intel 8080总线）MzT35C1模块支持intel8080总线，总线的最高速度可达20MHz（当然总线的速度能否达到最高接口速度，还与用户的总线布线、线长等有关），也就是说，如果控制MCU速度足够快的话，是可以支持视频的显示的。
注意：MzT35C1模块的总线接口是8位的，也就意味着对显存的数据操作时，需要连续进行两次操作方可完成，先传高字节再传低字节；但对于寄存器的操作（写入寄存器地址，即A0为低时的写入操作）8位的操作方可。
三、MzT35C1与51硬件接口连接图本例程使用GPIO来模拟总线时序。
上图的模块供电为5V的模块，而模块的端口电平为3.3V的，所以在所有的51端口与模块间的连接串入了一个100欧的电阻，有关MCS51的其它电路不在图中画出，请用户具体参考其它的开发板文档进行了解。
