_lv_display_t

Member	Type	Description
`ext_data`	`lv_ext_data_t`
`hor_res`	`int32_t`	Horizontal resolution.
`ver_res`	`int32_t`	Vertical resolution.
`physical_hor_res`	`int32_t`	Horizontal resolution of the full / physical display. Set to -1 for fullscreen mode.
`physical_ver_res`	`int32_t`	Vertical resolution of the full / physical display. Set to -1 for fullscreen mode.
`offset_x`	`int32_t`	Horizontal offset from the full / physical display. Set to 0 for fullscreen mode.
`offset_y`	`int32_t`	Vertical offset from the full / physical display. Set to 0 for fullscreen mode.
`dpi`	`uint32_t`	DPI (dot per inch) of the display. Default value is `LV_DPI_DEF`.
`buf_1`	`lv_draw_buf_t *`
`buf_2`	`lv_draw_buf_t *`
`buf_3`	`lv_draw_buf_t *`
`buf_act`	`lv_draw_buf_t *`	Internal, used by the library
`flush_cb`	`lv_display_flush_cb_t`	MANDATORY: Write the internal buffer (draw_buf) to the display. '`lv_display_flush_ready()`' has to be called when finished
`flush_wait_cb`	`lv_display_flush_wait_cb_t`	Used to wait while flushing is ready. It can do any complex logic to wait, including semaphores, mutexes, polling flags, etc. If not set `flushing` flag is used which can be cleared with `lv_display_flush_ready()`
`flushing`	`volatile int`	1: flushing is in progress. (It can't be a bit field because when it's cleared from IRQ Read-Modify-Write issue might occur)
`flushing_last`	`volatile int`	1: It was the last chunk to flush. (It can't be a bit field because when it's cleared from IRQ Read-Modify-Write issue might occur)
`last_area`	`volatile uint32_t`	1: last area is being rendered
`last_part`	`volatile uint32_t`	1: last part of the current area is being rendered
`sync_cb`	`lv_display_sync_cb_t`	Used to synchronize changes between frame buffers between renders. Called for each area needing to be synchronized before rendering next frame.
`sync_wait_cb`	`lv_display_sync_wait_cb_t`	Used to wait while syncing is ready. It can do any complex logic to wait, including semaphores, mutexes, polling flags, etc. If not set `syncing` flag is used which can be cleared with `lv_display_sync_ready()`
`syncing`	`volatile int`	1: syncing is in progress. (It can't be a bit field because when it's cleared from IRQ Read-Modify-Write issue might occur)
`syncing_last`	`volatile int`	1: It was the last chunk to sync. (It can't be a bit field because when it's cleared from IRQ Read-Modify-Write issue might occur)
`sync_areas`	`lv_ll_t`	Sync areas (redrawn during last refresh)
`render_mode`	`lv_display_render_mode_t`
`antialiasing`	`uint32_t`	1: anti-aliasing is enabled on this display.
`tile_cnt`	`uint32_t`	Divide the display buffer into these number of tiles
`stride_is_auto`	`uint32_t`	1: The stride of the buffers was not set explicitly.
`rendering_in_progress`	`uint32_t`	1: The current screen rendering is in progress
`color_format`	`lv_color_format_t`
`inv_areas`	`lv_area_t[32]`	Invalidated (marked to redraw) areas
`inv_area_joined`	`uint8_t[32]`
`inv_p`	`uint32_t`
`inv_en_cnt`	`int32_t`
`_static_buf1`	`lv_draw_buf_t`	Used when user pass in a raw buffer as display draw buffer
`_static_buf2`	`lv_draw_buf_t`
`layer_head`	`lv_layer_t *`
`layer_init`	`void()(lv_display_t disp, lv_layer_t *layer)`
`layer_deinit`	`void()(lv_display_t disp, lv_layer_t *layer)`
`screens`	`lv_obj_t **`	Screens of the display Array of screen objects.
`sys_layer`	`lv_obj_t *`
`top_layer`	`lv_obj_t *`
`act_scr`	`lv_obj_t *`	Currently active screen on this display
`bottom_layer`	`lv_obj_t *`
`prev_scr`	`lv_obj_t *`	Previous screen. Used during screen animations
`scr_to_load`	`lv_obj_t *`	The screen prepared to load in lv_screen_load_anim
`screen_cnt`	`uint32_t`
`draw_prev_over_act`	`uint8_t`
`del_prev`	`uint8_t`	1: Draw previous screen over active screen
`driver_data`	`void *`	1: Automatically delete the previous screen when the screen load animation is ready Custom user data
`user_data`	`void *`	Custom user data
`event_list`	`lv_event_list_t`
`rotation`	`uint32_t`	Element of lv_display_rotation_t
`matrix_rotation`	`uint32_t`	1: Use matrix for display rotation
`theme`	`lv_theme_t *`	The theme assigned to the screen
`refr_timer`	`lv_timer_t *`	A timer which periodically checks the dirty areas and refreshes them
`last_activity_time`	`uint32_t`	Last time when there was activity on this display
`refreshed_area`	`lv_area_t`	The area being refreshed
`vsync_count`	`uint32_t`
`perf_label`	`lv_obj_t *`
