我暂时认为是可行的,因为在rm里发现了这句话
For LTDC outputs up to 24-bit (RGB888), if less than 8bpp are used to output for example
RGB565 or RGB666 to interface on 16b-bit or 18-bit displays, the RGB display data lines
must be connected to the MSB of the LCD-TFT controller RGB data lines. As an example, in
the case of an LCD-TFT controller interfacing with a RGB565 16-bit display, the LCD display
R[4:0], G[5:0] and B[4:0] data lines pins must be connected to LCD-TFT controller
LCD_R[7:3], LCD_G[7:2] and LCD_B[7:3].
