What is a serial screen?

Serial screen is a TFT color LCD display control module with serial communication, which can be connected to external devices such as PLC, inverter, temperature control instrument, data acquisition module, etc. The display screen can be used to display relevant data and write parameters or input operation instructions through touch screen, keys, mouse and other input units, thus realizing information interaction between users and machines. It is widely used in various display fields such as industrial automation, smart home appliances, transportation rails, data rooms, charging piles, power medical care, national defense security, and shared equipment.

Definition of serial port screen, LCD screen with serial control is serial port screen.

Detailed definition: a set of display solution by microcontroller or PLC with controller, the communication part of the display solution consists of serial communication, UART serial port or SPI serial port, etc. It consists of three parts: display driver board, housing and LCD liquid crystal display screen. It receives the commands sent from the serial port of the user's microcontroller and completes all the operations of drawing on the LCD.

Serial screen products generally consist of two parts: serial screen hardware equipment and serial screen operating software.

(1) The hardware part includes the processor, LCD, touch panel, FLASH storage, RS232 or 485 serial chip, audio and video decoding chip, SD card slot, etc. Some models contain WIFI, 4G, Bluetooth, voice recognition, face recognition, fingerprint recognition and other modules, of which the performance of the processor determines the performance of the serial screen products, is the core unit of the serial screen.

(2) The operating software is generally divided into two parts, namely "system software running in the serial screen hardware" and "screen configuration software running under the Windows operating system of the PC". Users must first use the screen configuration software of the serial screen to create the "project file", and then download the prepared "project file" to the processor and FLASH of the serial screen through the serial port of the PC and the serial screen, SD card, U disk, etc. to run.

The system software of the serial screen is used to drive the whole hardware to work together, including parsing, loading, running and refreshing the interface of the "project file", colleagues parsing serial communication, touch screen operation, data processing, data storage, etc., and through the serial port, WIFI, 4G, Bluetooth communication, voice recognition, face recognition, fingerprint recognition The peripheral devices such as voice recognition, face recognition, fingerprint recognition, etc. will respond.
