 The ``lcd_pcf8574`` and ``lcd_gpio`` display components allow you to use HD44780-compatible, character-based LCD displays 
 with ESPHome. This integration is only for LCD displays that display individual characters on a screen 
-(usually 16-20 columns and 2-4 rows), and not for LCD displays that can control each pixel individually.
