LCD control

Hi,

I am looking for colour graphics LCD with driver. The size could be something like 128 * 64. In LCD control i have few doubts as below.

  1. There are lot of types available like TFT, passive type etc. From this which one to choose based on application? My application is to make a handheld tool like a Gameboy.

  1. While sending the data to the LCD driver, how is font sixe of the letter, location of text, colouring of the text or graphical information and all controlled? Is it require seperate micro which will do all the above i had mentioned or the readily available library function or macro kind of function will be availble within the driver itself? Because i am not intersted in creating this library. I will do only send the information to be displayed and those coloring information. Please clarify my doubts.

  2. I have seen some information from the website. None of the supplier give these kind of information. only they give dimensioning details, features thats it. Please suggest me some site to clear my basics about the LCD.

Thanks in advance.

Regards, M.Nagarajan.

For this you need to either attend trade shows and look, or do some diligent web searching. The differences are mostly visual, and affect how useful the thing is going to be in sunlight, whether it needs backlighting, and how rapidly it can change the image.

Don't be surprised if you have to write a library. A 128x64 LCD isn't going to show much detail, and a library of 5x7 characters is pretty quick to come up with.

There are some sub-fields that you're just supposed to know the answers to, and LCDs seem to be one of them. Do web searches. Pay particular attention to articles by hobbyists -- often these are the best places to find "what everyone knows" spelled out for you.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
