Product Architecture & Technical Specifications of 2.8-inch Standard Serial Screen
The 2.8-inch serial screen belongs to our integrated HMI liquid crystal module series, an all-in-one color LCD display control board with a built-in serial port. Integrated with complete driving circuits, it communicates with embedded main controllers via UART, SPI, RS232, RS485, and other interfaces through simple instruction sets to realize fast information interaction. The standardized design consists of four core modules:
- Display Unit: 2.8-inch TFT LCD screen with configurable resolution, supporting 262K / 16M true-color display for clear picture presentation under complex light conditions.
- Control Unit: Independent MCU control board embedded with graphics processing engine and instruction parsing system, handling screen rendering and touch data collection independently without occupying the main controller’s computing resources.
- 통신 인터페이스: Multi-protocol compatible terminals including TTL, RS232, 및 RS485, fully compatible with single-chip microcomputers, ARM, DSP, and PLC main control platforms.
- Power Management Unit: Wide voltage design supporting 3.3V / 5V power input with built-in overvoltage protection to avoid black screen or crash caused by industrial voltage fluctuations.
