1. Standard 16×2 Character Layout, Universal Basic Display

The JGS1602W2501 adopts the classic 1602 two-line sixteen-character standard layout, capable of displaying device numbers, measured values, running status and fault codes. Suitable for text and numeric readout only, it is the most widely used entry-level character display across the electronics industry.

2. STN Gray Film Low-Reflection Process

The mature STN gray-film technology delivers low surface reflection, keeping characters clear and sharp under indoor workshop lighting. No static flicker and comfortable for long-time visual reading, ideal for instruments that run continuously.

3. SPLC780D Driver Compatible with HD44780

The classic character driver IC shares the same timing as the HD44780 standard. Ready-to-use open-source routines for 51 MCU, STM32 and Arduino are widely available, drastically shortening development and debugging cycles.

4. 6800 MPU Bus with 4Bit/8Bit Dual Mode

The 6800 parallel bus supports both 4Bit and 8Bit working modes. Low-pin MCUs can use 4Bit mode to save IO ports, while MCUs with sufficient resources can switch to 8Bit for faster screen refresh.

5. 5V Industrial Standard Power Supply

Operates on the universal 5V power rail shared by industrial control and MCU systems, eliminating the need for a boost circuit and simplifying the whole-machine power architecture.

6. -20~70℃ Wide Temperature Adaptability

Operating temperature -20℃ to 70℃, storage range -30~80℃. It maintains stable display without black screen or character fading in normal factories, vehicles and indoor equipment environments under long-term operation.

7. Multi Industry Application Scenarios

Industrial Instruments

PLC control panels, temperature & humidity meters, production line monitoring modules

Automotive & Vehicle Panels

Engineering machinery status panels, on-board auxiliary displays

Embedded Development Boards

51/STM32/Arduino learning boards, prototype verification terminals

Household Smart Appliances

Small appliance status prompts, simple numeric readout screens
