I am using stm32f429 disco board. I want to create a GUI with touchgfx and display it on the external 10.1" tft LCD display
Can anyone tell me how can I connect my stm32f4 board with tft display using RGB or LVDS interface and how to initialize its pins ?

Hello @MWasi.1 ,
You can refer to this AN4861 Application note LCD-TFT display controller (LTDC) on STM32 MCUs, describes the LCD-TFT display controller of the STM32F4 with hardware and pins configurations and application examples.
The ready-to-use examples available in the STM32CubeF4 firmware package can be a starting point:
STM32Cube_FW_F4_V1.25.1\Projects\STM32F429I-Discovery\Examples\LTDC\LTDC_Display_2Layers
STM32Cube_FW_F4_V1.25.1\Drivers\BSP\STM32F429I-Discovery\stm32f429i_discovery_lcd.c
STM32Cube_FW_F4_V1.25.1\Drivers\BSP\Components\ili9341\ili9341.c
Hope this helps you.

I mean 429 have only RGB interface and when you need connect external, you need around 30 lines
Maybe you can use or create reduction FFC cable board , but limit is length
When hw is ready next step is driver to init external display
