LCD screen as portable Monitor.

Your best bet is to come up with a different plan. Some people have used a viewfinder from an old tape video recorder for this sort of project.

You are unlikely to be able to directly feed composite video to an LCD taken from a camera (and it may be some other sort of display rarther than liquid crystal). The electrical interface to a camera display is different between different types of display.

Your will probably need to retain the display driver intergrated circuit, which might turn out to be intergrated into a camera control chip in a way that you can't practically repurpose.

If you really want to try this I suggest starting by scouring the web for service manuals and technical information on camera. Try to find some that list the display driver IC, then look for the display driver datasheets. Some are likely to be proprietary so you won't be able to find the information you need to control the display.

After you have identified a model of camera that you have enough information on how the display works to make use of it get a few of them. Disassemble them, probably desoldering the surface mount display driver IC and figuring out a way to connect wires to the display.

After you have got the display running seperatly in a test setup start designing a circuit to convert the output of your camera into a form you can put into the display. This will probably involve a video ADC and an FPGA.

The cost of development tools, desoldering equipment, cameras, PCB's, FPGA's and miscellaneous parts will vastly exceed the cost of all the other stuff so you might as well get a good video camera instead of a cheap one.

1: Get an analog video to LCD driver chip. You will have to research those devices and the LCD you have, to determine if they are compatible. 2: Make a fully digital system, with a digtial camera, video processor, , microprocessor. The video processor will be an FPGA or something, and gate data between the camera, display, and memory, and do the video compression/decompression. Or separate an all-in-on system, if possible. 3: buy a ready to use LCD video display.

Why not just buy an old 2.5 inch LCD TV?

You will most likely encounter some digital interface. So you will most likely need an FPGA or possibly an MCU. I don't think there's anything near a CVBS signal at all.

Gary you should buy a WIDE screen LCD and install it where your fat head now exists. You could display a good looking skinny head instead of that ugly fat mug of a head the now resides there. Have a nice day!
