Product Overview

This 1.5 inch round TFT LCD display is designed for engineers, product developers, and OEM manufacturers that need a reliable round LCD module for circular front-panel products and modern embedded interfaces. Compared with a traditional square or rectangular display, a circular TFT display offers a more natural fit for products built around rotary operation, radial menus, dial-style interfaces, and compact industrial design.

With a 38.15 × 38.15 mm active area and 360 × 360 resolution, the module supports clear presentation of icons, text, menus, status data, and circular UI elements. The ST77916 driver IC helps provide stable control performance, while support for MIPI, RGB, MCU, SPI, and QSPI enables broader integration across different hardware platforms and project architectures.

For projects that need a compact round screen display module with balanced performance and good interface flexibility, this product is a practical choice for both development and production-oriented use.

Who This Product Is Best For

Typical Application Scenarios

This 1.5 inch circular TFT LCD is best suited for compact products that require a round visual interface, modern front-panel styling, and practical embedded integration flexibility.

How to Choose the Right Interface

One of the main advantages of this round TFT LCD module is its broad interface flexibility. Choosing the right interface depends on your hardware platform, data throughput needs, available pins, and development architecture.

• Choose MIPI when your project requires faster display communication and is based on a platform that already supports MIPI display integration.
• Choose RGB when your controller platform is designed around parallel display output and you need a conventional embedded display connection method.
• Choose MCU when control logic and command-driven communication are more important than high-speed graphics throughput.
• Choose SPI when pin count and hardware simplicity are priorities in compact embedded projects.
• Choose QSPI when you want higher communication efficiency than standard SPI while keeping a practical serial interface approach.

If your team is still evaluating interface selection, it is best to confirm the main controller platform, target refresh requirement, available GPIO resources, and mechanical layout before final module matching.

Technical Specifications

Note: If you need datasheet support, interface confirmation, development board matching, or engineering selection assistance, this information can be confirmed according to your project requirements.

Optional Matching Driver Boards

To improve development efficiency and reduce early-stage integration workload, this 1.5 inch round LCD module can be used with optional matching driver boards for different project needs.

• Parallel Port Drive Board: Suitable for general embedded display evaluation and cost-effective functional validation.
• Rotary Control Display Board: Designed for round control systems and products based on circular interaction logic.
• AI Human-Computer Interaction Driver Board: Suitable for advanced HMI projects that combine smart display output with interaction control functions.

For development teams, these optional driver board solutions can help accelerate interface testing, demonstration setup, and early proof-of-concept work.

Customization Support

For OEM and embedded device projects, a display module often needs more than standard catalog specifications. This circular LCD display can be evaluated for project-based matching according to actual application requirements.

• Interface matching support for different controller platforms and development directions.
• Driver board recommendation according to evaluation or demonstration requirements.
• Project-based display selection for customers comparing circular display sizes and integration structures.
• Mechanical fit evaluation based on active area and outline dimension constraints.
• Application-oriented solution support for smart control devices, thermostats, and compact embedded terminals.

If your project has special requirements, it is best to confirm the application environment, interface preference, space limit, and development stage before selecting the final display solution.

Selection Guide Before Ordering

Before choosing this 1.5 inch round TFT LCD display module, it is recommended to confirm the following points to improve matching accuracy and reduce development revisions:

• Interface requirement: MIPI, RGB, MCU, SPI, or QSPI.
• Main controller compatibility: whether your hardware platform already supports the intended display communication method.
• Mechanical space limit: whether the product housing matches the active area and outline dimensions.
• Brightness expectation: whether 350 nits is suitable for the intended installation environment.
• Application type: thermostat, control panel, rotary UI, portable device, or industrial interface.
• Development stage: engineering sample evaluation, functional verification, or production-oriented design.
• Driver board need: whether a matching board is required to speed up testing and integration.

Why Choose a Round TFT LCD Instead of a Standard Rectangular Display

A round TFT LCD display is the better choice when the product itself is built around a circular industrial design, a radial menu structure, or a rotary interaction method. In those cases, a rectangular display can leave unused corners, create layout compromise, and weaken design consistency.

This 1.5 inch circular display module helps create a cleaner visual structure for compact devices while maintaining practical resolution, interface flexibility, and embedded integration value. For products designed around a knob, dial, thermostat, or circular HMI concept, it offers a more natural display solution than a standard square screen.

Why Choose This 1.5 Inch Round TFT LCD Display

This product combines the main qualities many engineering and OEM teams look for in a small circular display: true round structure, 360 × 360 resolution, ST77916 driver IC, multiple interface options, and a compact size suitable for modern smart devices.

If your project requires a 1.5 inch round LCD module, a circular TFT display for embedded systems, or a round screen solution for smart control products, this module offers a practical balance of structure, compatibility, and application flexibility.
