1.5 Inch Circular TFT LCD Module

 

ENH-TV0150I001 Description

Product Parameters:

Screen Size & Shape: 1.5-inch Circular

A defining feature. The active display area is a full circle with a diagonal of 1.5 inches, achieving perfect unity between displayed content and physical form without visual waste, unlike square screens with circular masks.

Resolution: 360 (RGB) × 360 Pixels

This is an exceptionally high resolution optimized for a circular display area. Achieving over 129,000 pixels within a ~1.5-inch diameter circle results in a very high Pixel Density (PPI), delivering extremely fine detail and smooth edges, far surpassing square screens of similar size with lower resolution.

Viewing Angle: All-Viewing Angle

Almost certainly employs IPS (In-Plane Switching) technology. This means color and luminance remain highly consistent from the front, sides, and all other viewing angles, with minimal color shift, whitening, or contrast loss, vastly expanding the usable viewing range of the device.

Outline Dimensions: 41.96mm × 40.46mm × 2.16mm

Key Mechanical Data: 41.96mm x 40.46mm is the rectangular bounding box dimension including the driver circuit and bezel, providing precise spatial reference for structural design. The 2.16mm thickness is well-controlled, aiding in sleek product design while ensuring structural integrity.

Interface: QSPI

Quad Serial Peripheral Interface. This is an enhanced version of standard SPI, using 4 data lines for parallel transmission, offering a theoretical data rate 4 times faster than traditional SPI (1 data line). This is crucial for driving the high-resolution 360x360 screen, significantly improving refresh rates, reducing data transfer bottlenecks, and ensuring smooth performance for complex GUIs and animations.

Driver IC: ST77916

This is a powerful TFT-LCD driver controller. Its core value lies in:

High Performance: Built-in large GRAM efficiently handles high-resolution graphics data, supporting rich color depth (e.g., 16/18-bit RGB).

Advanced Features: Typically supports display rotation, flexible window address setting, partial refresh (updating only part of the screen to save power), hardware-accelerated drawing commands (lines, fills), greatly offloading the host processor and simplifying software development.

Optimization for Circular Displays: Perfectly adapts to the circular active area, managing pixel addressing effectively.

Display Type: TFT-LCD

Utilizes mainstream active-matrix Thin-Film Transistor technology, where each pixel is controlled by its own transistor. This enables fast response times, high contrast, vibrant color saturation, and excellent dynamic image display capability.

 

 

Application Fields:

1.Premium Wearable Devices

   a.Core Applications: Smartwatches with classic round dials, high-end fitness bands, professional sports instruments (e.g., bike computers, treadmill displays).

   b.Problem Solved: Perfectly replicates the elegant circular aesthetics of traditional watches, meeting user expectations for premium wearables. The ultra-high 360x360 resolution delivers an extremely high pixel density (PPI) within the circular area, resulting in exceptionally sharp, anti-aliased displays of watch faces, sports data charts, map traces, and photos. The all-viewing angle ensures clear readability at any wrist orientation.

   c.Advantage: The QSPI interface provides high data transfer rates, enabling smooth rendering of complex animations, high-frame-rate sweeping hands, and rapidly updating sensor data for a seamless user experience.

2.Automotive & Industrial Instrumentation

   a.Core Applications: Motorcycle/E-bike digital dashboards, automotive auxiliary information displays (e.g., TPMS, climate control), status indicator dials for industrial equipment.

   b.Problem Solved: The circle is the classic form for instrumentation. This screen can directly replace traditional mechanical gauge clusters, enabling fully digital, customizable displays of speed, RPM, navigation arrows, warning icons, etc. High brightness and contrast ensure visibility even under strong ambient light (e.g., sunlight).

   c.Advantage: The powerful ST77916 driver chip enables fast rendering of dynamic graphics, responding to real-time changes in vehicle data. Its robust build (2.16mm thickness) better withstands the slight vibrations common in vehicular environments.

3.Smart Home & Consumer Electronics

   a.Core Applications: High-end smart speaker touch panels, smart thermostats, beauty device displays (e.g., facial cleansers, RF devices), interfaces for premium coffee makers/appliances.

   b.Problem Solved: Infuses home appliances with a modern, technological feel. The circular screen naturally complements the design language of many appliances with physical knobs or round bodies, serving as an interactive hub for music visualizers, cooking progress, device modes, and ambient information.

   c.Advantage: The circular design itself is a statement, significantly enhancing product appearance and brand differentiation. The QSPI interface allows the host MCU to update the display more efficiently, reducing system load.

4.Medical & Health Devices

   a.Core Applications: High-end portable patient monitors, digital stethoscope displays, smart pill dispensers, physiotherapy equipment.

   b.Problem Solved: In medical contexts, a circular screen can intuitively present radial data charts (e.g., heart rate waveform rings, SpO2 trend circles) with excellent clarity. High resolution ensures small medical text is legible.

   c.Advantage: Excellent color performance can be used for color-coded displays (e.g., different temperature ranges in different colors), improving information recognition efficiency. The driver chip typically supports low-power modes suitable for portable devices.

5.HMI (Human-Machine Interface) & Specialized Equipment

   a.Core Applications: Dedicated controllers, portable test equipment, gaming peripherals (e.g., steering wheel center display), professional photography equipment displays.

   b.Problem Solved: Provides a compact, high-information-density circular viewport for specialized equipment. It can display parameter knob menus, mode selection rings, precise scale indicators, etc., where the interaction logic perfectly matches circular hardware controls.

   c.Advantage: The 41.96mm outline dimension makes it easy to integrate into various equipment front panels. The high speed of QSPI meets the demanding responsiveness requirements of professional equipment interfaces.
