Hi i am working with LTDC with STM32F429ZI Discovery -1 board with onboard LCD. I really want to drive a external LCD RGB display without An ic controller by utilising the Internal LTDC hardware inside the MCU . Can you please give some support on this

What kind of support? It's basically a circular DMA of the frame buffer which would come out of the SDRAM. It outputs the the R G B parallel pin, so you'd have to remove the display and wire your own up.
Resolution up to about 1.3Mpixel
You just have to set the clocking and horizontal/ vertical line timings.
