  lv_st_ltdc_create_direct [#lv_st_ltdc_create_direct]

  Create a direct render mode display bound to a LTDC layer.

  ```c title=" " lineNumbers=1
  lv_display_t * lv_st_ltdc_create_direct(void *fb_adr_1, void *fb_adr_2, uint32_t layer_idx)

  | Name        | Type                        | Description                                                                    |
  | ----------- | --------------------------- | ------------------------------------------------------------------------------ |
  | `fb_adr_1`  | `void *`                    | The LTDC layer's framebuffer memory address.                                   |
  | `fb_adr_2`  | `void *`                    | An additional framebuffer-sized buffer to use for double buffering, or `NULL`. |
  | `layer_idx` | <ApiLink name="uint32_t" /> | The LTDC layer number to bind the display to. Typically 0 or 1.                |

  **Returns:** <ApiLink name="lv_display_t" display="lv_display_t *" /> — The display.

<ApiMember kind="function" name="lv_st_ltdc_create_partial" file="drivers/display/st_ltdc/lv_st_ltdc.h" line="52" url="https://github.com/lvgl/lvgl/tree/a7b95c5b0839ce901c09c205610bc2c77cc3345d/src/drivers/display/st_ltdc/lv_st_ltdc.h#L52">
  lv_st_ltdc_create_partial [#lv_st_ltdc_create_partial]

  Create a partial render mode display bound to a LTDC layer. The layer's framebuffer is flushed to internally. Enable `LV_ST_LTDC_USE_DMA2D_FLUSH` for parallel flushing.

  ```c title=" " lineNumbers=1
  lv_display_t * lv_st_ltdc_create_partial(void *render_buf_1, void *render_buf_2, uint32_t buf_size, uint32_t layer_idx)

  | -------------- | --------------------------- | --------------------------------------------------------------- |
  | `render_buf_1` | `void *`                    | A render buffer.                                                |
  | `render_buf_2` | `void *`                    | An additional render buffer for double-buffering, or `NULL`.    |
  | `buf_size`     | <ApiLink name="uint32_t" /> | The size of the buffer(s) in bytes.                             |
  | `layer_idx`    | <ApiLink name="uint32_t" /> | The LTDC layer number to bind the display to. Typically 0 or 1. |

  **Returns:** <ApiLink name="lv_display_t" display="lv_display_t *" /> — The display.
