TFT serial port screen driver dedicated chip
The TFT Serial Communication Module (commonly known as the Smart Serial LCD Screen) is an intelligent LCD display module that enables communication with the main control MCU via a standard UART interface. It integrates a high-performance display controller, graphics acceleration engine, Flash storage, and a complete GUI firmware system, with all image rendering, touch processing, and animation playback handled autonomously by the screen. The main control MCU only needs to send simple command frames via UART to achieve complex interactions such as text display, image switching, and button triggering, significantly lowering the development threshold for Human-Machine Interface (HMI) in embedded systems.
Core Technologies and Hardware Solutions
TFT serial interface screens typically consist of two main components: hardware and operating software. The hardware components include a processor (such as ARM Cortex-M series or dedicated ASIC), TFT LCD display, touch screen (resistive or capacitive), FLASH memory, and serial interface chips. Currently, the mainstream hardware solutions from Microchip include:
Basic series based on STM32 MCU + FPGA
The IoT Series Based on ITE9854, ITE976, and ITE9866
F Series Based on AD STAR
Medical-grade M Series Based on Allwinner F1C100S
Control chips based on small-size MCU interfaces (e.g., ZLG MH22D3), specifically designed for screens below 3.5 inches with resolutions up to 800*480, supporting UART communication and a wide range of graphics processing commands.
Microchip's Development Approach and Software Ecosystem:
The development of serial display screens adopts a "what-you-see-is-what-you-get" configuration approach. Developers use the PC-based graphic configuration software (VCOM GUI Designer) for UI design, control drag-and-drop, and logic programming. The compiled project files are downloaded to the screen's Flash via serial port, SD card, or USB drive for execution. The system software handles project file parsing, touch event processing, and serial communication, supporting multiple standard protocols to free engineers from low-level drivers and focus on business logic.
