Is it possible to use an old tablet screen as a tft screen for the arduino??? if so, how? Please HELP!!!
Sorry but i'm not that experienced with the arduino yet
P.S there is a sd card slot on the tablet if this helps and also the tablet doesn't work so it doesn't matter about the cost of using it
I'm sorry to disappoint you. You can not use screen from the tablet as it is.
I'm pretty sure that tablet you disassembled(or not yet...) has a SoC (system on chip) design. This means that TFT controller, ARM processor, Ethernet MAC ... and so on... are included in the main chip on the motherboard.
Basically you have a TFT screen without controller.
To use TFT screen you need a specialized controller for that type of TFT. (I guess 7 inch screen).
Slightly off topic: I just started a project on my own (based on FPGA / CPLD) to make a controller for 7 inch TFT to be used in Arduino enviroment. But it will take months to first results. This is the main reason why I decided to "dig" in this section of Arduino Forum.
