3.5 inch TFT LCD Display Screen: Common Interface List
With the continuous advancement of technology, TFT LCD screens have become a popular choice in the field of display equipment. There are many sizes to choose from on the market, among which the 3.5 inch size is very popular. This article will introduce in detail the common interfaces of 3.5 inch TFT LCD screens to help you better understand and choose products that suit your needs.
First, let’s take a look at the basic characteristics of the 3.5 inch TFT LCD screen. It uses thin film transistor technology, which has the advantages of high brightness, high contrast and high refresh rate, and can present clear and colorful image effects. Moreover, due to its compact size, it is suitable for use in various portable devices, such as mobile phones, digital cameras, portable game consoles, etc.
In terms of interfaces, 3.5 inch TFT LCD screens usually have a variety of options to meet the needs of different devices. Let me introduce them one by one to you.
1. Serial interface (SPI)
The first is the serial interface (SPI), which is a common digital interface suitable for various small devices. It has the advantages of simple wiring and low cost, but the transmission speed is slow and is not suitable for applications with high speed requirements.
2. Parallel interface
The second is the parallel interface, which is a faster transmission interface and is suitable for some devices that require high-speed data transmission. It improves the efficiency of data transmission by transmitting multiple data bits at the same time, but compared to the serial interface, its wiring is more complicated and the cost is relatively high.
3. I2C interface
In addition to the above two interfaces, another common interface is the I2C interface, also known as the TWI interface. It is a serial communication interface suitable for connecting multiple devices. It has simple wiring methods and flexible expansibility, but the transmission speed is slow, so it is suitable for some devices that do not have high speed requirements.
4. RGB interface
In addition, there is another common interface is the RGB interface, which is an analog interface and is suitable for some application scenarios with high color requirements. It transmits red, green, and blue color signals through three signal lines respectively, which can display richer and more delicate color effects.
In summary, common interfaces for 3.5 inch TFT LCD screens include SPI, parallel interface, I2C interface and RGB interface. Each interface has its applicable scenarios and characteristics. When choosing, you need to comprehensively consider the actual needs and choose the most appropriate interface type.
This article provides a detailed analysis of the common interfaces of 3.5 inch TFT LCD screens, hoping to help readers better understand and choose products that suit their needs. If you are interested in TFT LCD screens, hurry up and learn about it!
