GreenTemp Controls is specializing in smart home energy management. Their latest thermostat needed a modern display to replace outdated segmented LCDs, enabling real‑time presentation of temperature, humidity, voltage, system status, and more – all within a compact, user‑friendly interface.

Customer Requirements for 2.4″ TFT

• High readability under various indoor lighting conditions (daylight, dim rooms, night mode)

• Full‑color & rich data presentation – simultaneously show temperature (e.g., 25.4°C), voltage (243V), humidity (45.1%), RF signal strength (-44dBm), timer, mode icons, etc.

• Wide viewing angle (wall‑mounted thermostats are viewed from different angles)

• Low power consumption (battery‑powered or low‑power extraction thermostats require energy efficiency)

• Touch option for intuitive control (ON/OFF, mode switching, setpoint adjustment)

• Stable performance under voltage fluctuations (UK mains 230V ±10%)

• Compact 2.4″ size fits standard wall backboxes

Problems Solved by Our 2.4″ TFT on Their Thermostat

1. Replaced outdated segmented/character LCD – The old display could only show limited numbers; now it presents rich icons (TGEAR, OFF/ON, ratio 1/1, dBm, etc.) and multiple parameters at a glance.

2. Improved user interaction – Optional capacitive/resistive touch eliminates physical buttons, enabling a sleek, flat‑panel design.

3. Enhanced visibility in low light – Built‑in LED backlight with adjustable brightness solves nighttime readability issues.

4. Reduced assembly complexity – Standard 2.4″ module with FPC connector integrates easily into the customer’s PCB, shortening time‑to‑market.

5. Real‑time system diagnostics – Voltage, signal strength, and operating status can be displayed, helping users and technicians troubleshoot remotely.

Key Advantages of Goldenvision 2.4″ TFT

• IPS Full Viewing Angle (80°/80°/80°/80°) – No colour distortion even when viewed from the side or below.

• High Brightness (up to 500 cd/m²) – Readable under direct sunlight or bright indoor lighting.

• Ultra‑Low Power Consumption – Optimised driver IC and backlight design (typical 40mA @ 3.3V), ideal for battery‑backed thermostats.

• Wide Temperature Range (-20°C to +70°C) – Suitable for UK homes (including unheated rooms or near windows).

• Customisable Interface – Supports SPI/RGB/MCU interfaces; optional resistive or capacitive touch panel.

• Plug‑and‑Play Integration – Standard 2.4″ (240×320 or 320×480 resolution) with 24‑pin FPC, compatible with common thermostat MCUs (STM32, ESP32, NXP).

• Cost‑Effective – Mass production with consistent quality (ISO9001 factory), offering lower total cost than European or Japanese equivalents.
