    LED Matrix Display with 4094 Shift Register

    CD4094 same as 74HC595, About display refresh : step1.Choose firt row,and shift first row data to 4094/595,and then lock and enable output,after enable out put must delay some time; step2.Choose No.2 row and just like step1 ....... if finish all rows,return step 1,

    Dot Matrix led display not same brightness.

    Here https://www.edaboard.com/threads/234654/ I share a sample of the matrix display,maybe a little help to you

    Dot Matrix led display not same brightness.

    I think maybe it's firmware problem,can you show your code?

    [SOLVED] PIC24HJ502, TLC5940, C Code

    Yes,I not fond any nice codes too,thank you share.but if know it's how to work,and see the datasheet,timing,it's easy to drive,right?I think principle is important than code.

    Good job!Now,i driver one 32x256RGB LED matrix display.but i not use PIC MCU and TLC5940.however,i think you are doing very nice project!if you can drive more area,and add communication,PC message editer software,it's will be perfect!

    two color led display command board from Tecnovision

    It's a beautiful control board! If you can't find PC software,why not buy new LED matrix control board?I think it's easy to work again.... Good luck!

    The LED matrix display enthusiasts,Can you show where you want to used?

    Usually,the matrix display is used to show message.Advertisement,signal...Maybe just to learn is possible. But i really want to know where you want to use?Can you talking about it?
