1. Based on the displayed content:
The TFT type LCD display module can be divided into three types of LCD modules: pen segment type, character type, and graphic dot type.

1. The TFT type LCD display module mainly displays the digits, 8 characters, and fixed icons of 7 stroke segments.

Advantages: LCD control drive is connected to the interface of MCU, with simple process and low price. It is widely used in small household appliances such as temperature hygrometer, electronic scale, multimeter, smart meter, air conditioner, microwave oven, rice cooker, etc.

Defect: Lack of visible content.

2. The TFT type LCD display module mainly displays Arabic numerals, English letters, and ASCII Western characters.
Advantages: The LCD control driver is equipped with an ASCII Western character dot matrix generator, and the microcontroller only needs to send ASCII character codes to display the corresponding characters on the LCD. The price is moderate, especially suitable for displaying Latin letters. Widely used in various industrial control equipment, communication equipment systems, environmental protection series, financial series, etc.

Defect: Only ASCII characters can be displayed, making it difficult to display characters on a large scale.

3. The graphic dot matrix TFT type LCD display module mainly displays the graphic dot matrix.
