1.69 Inch Rounded Square TFT LCD Display

ENH-TV0169A001 Description

This 1.69-inch rounded square TFT LCD display is engineered for developers and engineers who demand a compact screen that delivers reliable, consistent performance-both on the spec sheet and in real-world device integration.
Core Display Specifications
Display Type: 1.69" IPS TFT, transmissive, normally black
Viewing Direction: Full 360° viewing, zero color shift at any angle
Driver IC: ST7789V2 – the industry's most stable, library-compatible driver for Arduino, ESP32, STM32, and Raspberry Pi platforms
Operating Temperature: -20°C to +70°C
Storage Temperature: -30°C to +80°C
Backlight: 3 integrated white LEDs
Luminance: 480 cd/m² (typical) – fully readable in direct indoor light and outdoor shaded conditions
Why These Specs Elevate Your Design
The normally black IPS panel delivers true deep black when powered off, a critical feature for medical wearables and consumer devices where a faint gray off-state can compromise premium aesthetics.Its rounded square form factor (240×280 resolution) offers more usable UI real estate than a circular display, while fitting seamlessly on wrist-worn devices or compact dashboards without the harsh edges of a standard rectangle.The ST7789V2 driver is more than just a component-it unlocks access to thousands of pre-built code examples, open-source libraries, and community support, eliminating the need to write custom SPI drivers from scratch.
Ideal Use Cases
Smartwatches, fitness bands, portable glucose meters, handheld patient monitors, e-scooter dashboards, smart home controllers, and industrial handheld terminals.
Key Advantages Over Competing Displays
Simplified Integration: The 4-wire SPI interface requires only 6 GPIO pins (including backlight control), freeing up valuable I/O for sensors, buttons, or wireless modules.
Uncompromised Viewing Angles: IPS technology delivers 80° visibility in all directions, ensuring clear, accurate colors for users viewing the screen from any angle-perfect for watches and vehicle dashboards.
Industry-Leading Brightness: At 480 cd/m², this panel outperforms most 1.69-inch alternatives (typically 300–350 nits), maintaining readability in bright, sunlit environments.
Ultra-Compact Form Factor: With a module thickness of just 2.76mm and a weight of 8g, it fits into slim wearable enclosures without forcing design compromises.
Robust Temperature Performance: The -20°C to +70°C operating range ensures reliable function in cold outdoor e-scooters and hot industrial control rooms alike.
Proven Real-World Deployments
This 1.69-inch rounded square TFT LCD display is already in mass production for customers across five key industries, with proven performance in:
Wearable Medical Devices: Blood oxygen meters, portable ECG monitors, and insulin pump controllers, where high brightness and full viewing angles ensure critical patient data is visible from any wrist position.
Smartwatches & Fitness Trackers: The rounded square design offers a modern, ergonomic upgrade over circular screens, providing more space for notifications and fitness metrics while maintaining a sleek aesthetic.
IoT Control Panels: Smart locks, thermostats, and air quality monitors, with the SPI interface enabling straightforward integration with ESP32 and Raspberry Pi.
E-Scooter & E-Bike Dashboards: Rounded corners reduce stress points on device housings, while 480 nits of brightness keep the display readable in direct sunlight.
Handheld Industrial Meters: Compact size, wide temperature tolerance, and the stable ST7789V2 driver make it a trusted choice for field service tools.
Physical & Optical Performance
Active Area: 27.97mm × 32.63mm – ample space for clean, intuitive UI layouts with icons and text.
Module Dimensions: 31.0mm × 18.0mm × 2.76mm – compact enough for the tightest enclosures.
Connector: 8-pin, 2.54mm pitch single-row header – easy for hand-soldering and breadboard prototyping, with no fragile ZIF connectors required.
Optical Quality: The IPS panel delivers consistent, accurate colors across all viewing angles, and the normally black mode enables true black backgrounds-ideal for the dark-mode UIs standard in wearables and medical devices.
Backlight Uniformity: All 3 white LEDs are binned to ensure even illumination across the entire active area, with no hotspots or dark edges.
Driver Support: The ST7789V2 comes with pre-written initialization sequences, and we provide full wiring diagrams and sample code for Arduino, ESP-IDF, and Raspberry Pi (SPI).
Factory-Quality Reliability You Can Trust
We manufacture this module in our own ISO9001:2015 certified facility, with every batch undergoing rigorous testing before shipment:
72-hour high-temperature aging (50°C)
Thermal shock testing (-30°C ↔ 80°C, 10 cycles)
ESD testing (contact ±4kV, air ±8kV)
Full RoHS and REACH compliance, with complete documentation ready for EU/NA customs clearance
We also guarantee 3–5 years of continuous production for this model, with no sudden end-of-life notifications, and a monthly production capacity of 500,000 units to scale with your order volume.
Customization Options Tailored to Your Project
As the original manufacturer, we offer flexible modifications that distributors cannot match:
FPC Shape & Connector Type: Custom pinouts, ZIF connector integration, or flexible PCB redesign to match your device housing, with engineering samples available in 15–20 days.
Cover Glass & Coatings: Silk-screened logos, anti-glare (AG), anti-fingerprint (AF), or anti-shatter film treatments.
Touch Panel Integration: Capacitive touch (CST816T or FT series) or resistive touch, fully integrated into the module.
Backlight Customization: Brightness upgrades to 800–1000 nits (custom) or adjusted LED color temperature.
Interface Modifications: Conversion from 4-wire SPI to MCU 8080 parallel or RGB interface (minimum order quantities apply).
