# Display LVGL Demos

This example shows LVGL internal demos with RGB LCD.

For common issues about RGB LCD, please refer to [LCD Development Guide](https://docs.espressif.com/projects/esp-iot-solution/en/latest/display/lcd/lcd_development_guide.html#common-problems).

## How to use the example

### Hardware Required

* ESP32-S3-LCD-EV-Board or ESP32-S3-LCD-EV-Board-2
* USB-C Cable

### Compile and flash

```
idf.py -p COMx build flash monitor
```
