+### `component.is_idle` Condition
+
+This condition checks if a given component is idle. A component is considered to be idle if it has completed
+setup, has not been marked as failed, and is not currently being called by the loop task. This is useful for
+synchronizing actions with the state of the component, for example, an e-paper display component that requires
+a significant amount of time to update the display panel.

 To use LVGL with a [display](#display-hw) in ESPHome, you'll need an ESP32 or RP2040. PSRAM is not a strict requirement but it is generally recommended, especially for large color displays.
 
-The graphic display should be configured with `auto_clear_enabled: false` and should not have any `lambda` set. The LVGL component will take care of the display rendering. For most displays, the `update_interval` should be set to `never`, but note that some displays such as OLED and ePaper will need the update interval set to a suitable value.

 This [trigger](#lvgl-automation-triggers) is triggered after LVGL has been setup. It is also available on any widget, but the timing is the same.
 
+### `on_draw_start`
+
+This [trigger](#lvgl-automation-triggers) is executed before each LVGL drawing operation.
+
+### `on_draw_end`
+
+This [trigger](#lvgl-automation-triggers) is executed after LVGL has completed drawing all updated screen elements. It
+may be used for example to trigger an update of a display component like an e-paper screen that requires the buffer
+to be sent to the display for it to be updated.
+
+```yaml
+lvgl:
+  on_draw_end:
+    component.update: my_display_id
