Laptop LCD Display to VGA Interface

Now this is a project i always wanted to build, but never had the chance, or the mood. Its kind of complicated, so beginners shouldn’t approach this project. Thats probably the reason i did not build it myself because when it first came up to me this idea i was still a beginner and did not had enough experience, and even now when i can say i have some experience i still could get in trouble with this project. The author of this project explains the problems that he came across and how he solved them. You should expect some pixels looking distort, the project its a work in progress and even in the final form you cant get perfect results. Unfortunately the author fried its panel until the completion of the project by accidentally switching the +12V and +5V lines. So he says it will finish the work on project as soon as he gets a new LCD panel.

Since so many people showed interest in the LCD to VGA interface project I decided I updated this article with some new info. For example this guy did it to his 5 inch TFT LCD, and he used the following schematic:

You might considering the standard VGA pinout before anything else on this project, because you are basically taking a signal from the VGA output and interfacing it with the LCD input:

Basically you’re gonna have to supply to your LCD panel RGB and sync signals and you might use the following schematic which provide RGB signals + composite sync signal :

Remember I haven’t tried these schematics myself, I’m just referencing them to help you get the info. To get the full insight you should follow the links provided. Good Luck on your LCD to VGA interface.
