What is TP+LCD?
 

TP+LCD is a common touch screen combination scheme, as follows:
 

TP: short for Touch Panel, also known as touch screen, is mainly used to receive user touch input operations, such as clicks, swipes, etc., to achieve human-computer interaction.
 

LCD: It is an abbreviation for Liquid Crystal Display, which is a liquid crystal display screen used to display information such as images and text.
In practical applications, TP is usually placed above the LCD and combined to form a touch enabled display screen, which is widely used in electronic devices such as smartphones, tablets, and e-books.
