The LCD screen on the K210 is an 8-bit spi parallel interface, and the model of the screen development board used is JLT32009A, which should be available for purchase.
It should be noted that if you buy this kind of screen in a certain treasure, there will generally be a difference between 8 and 16 bits. The merchant will tell you that these are two different screens, but we will find that by checking the specifications of the screen, as long as Jumping resistors can switch between 8-bit and 16-bit. There are many resistors on the screen cable. Find R8 and R16. R8 represents an 8-bit data signal, and R16 represents a 16-bit data signal.
Then check the schematic diagram as follows:
