Breakdown of Key Specs

80×160 Resolution This 1.42-inch screen carries 80×160 pixels, roughly 126 PPI. At this form factor, the resolution produces sharp text, clear icons and smooth graphics. It's perfect for showing time, push notifications, heart rate data and simple UI interfaces on wearables. The 1:2 aspect ratio also works great for vertical layouts widely used on smartwatches and fitness bands.

IPS All-Angle Viewing Built with IPS technology, the screen maintains steady colors and contrast no matter which angle you view it from. Standard TN panels easily fade when viewed sideways, but our IPS panel stays readable. Users can check their smartwatch at any wrist tilt, and operators can view portable devices from the side without struggling to see content.

ST7735 Driver IC ST7735 is a mature, widely adopted driver among hardware developers and makers. It runs on SPI communication and includes built-in GRAM, so you won't need extra external frame buffer chips. Plenty of ready-made libraries support this IC, such as Adafruit ST7735 and ST7735_LTSM for Arduino. Developers can also find stable MicroPython drivers for ESP8266 and Raspberry Pi Pico.

4-Wire SPI Interface The 4-wire SPI only requires SCL, SDA, DC, CS signals plus power and ground. It saves plenty of GPIO resources on microcontrollers - a huge plus for wearable products where PCB space is always tight.

350 cd/m² Brightness At standard 350 cd/m² brightness, the screen is easy to read indoors and under moderately bright surroundings. The dual white LED backlight only draws 40mA at 3.3V, making it a solid fit for battery-powered products.

Wide Temperature Range It operates reliably between -20°C and +70°C, and can be stored at temperatures ranging from -30°C to +80°C. That makes it suitable for consumer, industrial and outdoor equipment that faces temperature shifts.

Transmissive Normally Black Mode In normally black mode, pixels turn black without voltage input. This delivers deeper blacks and higher contrast. It pairs nicely with dark mode interfaces commonly seen on wearables and helps lower overall power consumption.

Application Scenarios

Smart Watches & Fitness Trackers The 1.42-inch screen with 80×160 resolution displays time, step counts, heart rate readings, alerts and activity data. IPS wide viewing angles guarantee clear visibility no matter how users rotate their wrists.

Wearable Health Monitors A great match for blood pressure monitors, ECG equipment and pulse oximeters, taking advantage of its clear visuals and low power usage.

Portable Medical Devices Handheld diagnostic tools, electronic thermometers and glucose meters use this module for simple, legible data readouts both at home and in clinics.

IoT & Smart Home Devices Commonly integrated into thermostat panels, smart sensors and control interfaces to display real-time local status.

DIY Projects & STEM Education Compatible with Arduino, ESP32, STM32 and Raspberry Pi. It's a popular choice for hobby builds and teaching kits.

Industrial Handheld Terminals Installed on portable testing gear, data loggers and calibration instruments to display parameters and navigation menus.

Main Product Strengths

Compact 1.42-inch footprint The small outer dimensions suit space-limited hardware designs. Whether you develop smart rings, fitness bands or portable sensors, this display offers enough viewing area without bloating your product structure.

IPS wide viewing angle panel Colors and contrast remain consistent from every viewpoint. This is essential for wrist wearables, as users constantly change viewing angles during daily use.

ST7735 IC with rich development resources It's one of the most mainstream driver ICs in embedded development. Ready libraries for multiple mainstream platforms help engineers get the display working quickly and shorten development cycles.

4-wire SPI saves MCU pins Minimizes pin occupation on controllers, leaving extra GPIO ports for sensors, buttons and wireless modules.

Low power consumption 3.3V operating voltage and low backlight current work well for battery-operated wearables. Normally black mode further optimizes power efficiency for dark UI designs.

Strong temperature resistance Stable performance under varying temperatures for consumer, industrial and outdoor equipment.

350 cd/m² standard brightness Delivers good visibility indoors. We can also supply high-brightness versions for outdoor use upon request.

RoHS compliant All materials meet RoHS standards to satisfy global electronic market requirements.

Target Industries

Wearable Electronics Smartwatches, fitness trackers, smart rings and health trackers. The compact size balances display content capacity and miniaturized product design.

Medical & Healthcare Portable blood pressure monitors, glucose meters, pulse oximeters, ECG devices and thermometers benefit from clear visuals, wide viewing angles and low power draw.

IoT & Smart Home Thermostats, air quality monitors, smart appliance control panels and home automation hubs rely on this module for local status display and user interaction.

Industrial Control Handheld testers, calibration equipment and portable data recorders. Its wide operating temperature fits typical factory environments.

Consumer Electronics Smart remote controllers, compact portable players and battery status indicators.

Maker & Education Market Works with most mainstream development boards. Existing open-source libraries greatly cut down driver development work.

Customization Options

FPC Configuration Standard units come with gold-plated FPC connectors. We can adjust FPC length, outlet direction based on your enclosure layout and PCB design.

Backlight Solution Two white LEDs provide even lighting across the active area. Standard brightness reaches 350 cd/m² at 40mA, 3.3V. Backlight brightness and color can be adjusted for different ambient conditions.

Normally Black Transmissive Panel Pixels show pure black when inactive, lifting contrast and bringing a premium visual effect, ideal for dark-mode wearables.

Mechanical Adaptation Slim body for easy assembly into thin casings. We provide 2D mechanical drawings together with samples to support your structural design.

Surface Treatment Anti-glare coating is standard to reduce reflections under bright light. Extra surface treatments are available on demand.

Built-in ESD Protection Integrated ESD circuits keep the module stable during production and long-term field operation.

Manufacturer Custom Services

As the direct LCD factory, we support multiple custom modifications for this 1.42-inch TFT module:

FPC Customization Adjust cable length, outlet direction (bottom, side or special angle), connector type (ZIF, pin header or custom pads), mounting holes and gold finger sizes. Custom FPC tooling usually takes 3–4 weeks.

Touch Panel Bonding Capacitive touch panels with FT3267 / CST826 IC or resistive touch are available. Adding CTP increases total thickness by roughly 0.6 mm. Optical bonding and air bonding are both optional.

Cover Glass Tempered cover glass with anti-glare, anti-fingerprint coating, or custom silk printing for logos, borders and function marks. Lead time for custom glass moulds is about 4–5 weeks.

Brightness & Backlight Tuning Standard brightness: 350 cd/m². We can develop high-brightness versions ranging from 600 cd/m² up to 1000 cd/m² for strong outdoor light. Changes may require adjusting LED quantity or optical film layers.
