Product Description

I. Consumer Electronics and Portable Devices: Core of Small Screen Interaction

In these scenarios, "lightweight display + low cost" is required. The compact size of the module and the simple SPI interface enable quick integration and meet the basic information visualization needs:

Portable Monitoring Devices: Such as a mini thermometer (displaying real-time temperature and humidity values + simple trend curve), a mini air quality detector (displaying PM2.5 concentration, VOC level + corresponding icons), a step counter (displaying steps, calories, and exercise duration), no need for complex images, only clear presentation of key data;

Small Intelligent Control Terminals: Such as a smart home remote control (controlling lights / air conditioners, displaying current mode, temperature, and battery level), a mini Bluetooth speaker (displaying volume, playback status, song name abbreviation), a e-cigarette / aromatherapy machine control panel (displaying remaining battery power, working mode, and set time duration);

Children's Electronic Toys: Such as an intelligent story machine (displaying character icons, playing progress), a mini game machine (running pixel-level mini games, such as Snake, Tetris, with a 128×128 resolution sufficient to support simple animations), an electronic pet machine (displaying pet status, interactive feedback icons).

II. Industry and Internet of Things (IoT): Low-cost State Visualization

In industrial scenarios, a large number of "single-point monitoring / control nodes" do not require large screens. This module can achieve "state visualization" with low power consumption and small size, reducing the overall solution cost:

Sensor Node Display: Such as distributed sensors in factory workshops (displaying current pressure, flow, voltage, etc. parameters, displaying alarm icons when abnormal), small environmental monitors in agricultural greenhouses (displaying soil moisture, light intensity, CO₂ concentration), no need for networking to view data locally;

Device Status Indicators: Such as a small motor controller (displaying speed, operating mode, fault code), a charging station slave (displaying charging current, remaining time, charging status), an access control reader (displaying card swipe result, remaining permission times);

IoT Edge Terminals: Such as low-power Bluetooth (BLE) data collector, LoRaWAN terminal node (displaying network status, data upload progress, battery power), meeting the core requirements of edge devices for "low power consumption, small size".

III. Medical Health: Display End of Small Monitoring Devices

In medical scenarios, there is a strong demand for "personalized, portable" monitoring devices. This module's small size and stability can meet the basic health data display needs:

Home Mini Health Instruments: Such as a fingertip blood oxygen meter (displaying blood oxygen saturation, heart rate values, with color indication for normal / abnormal), mini blood pressure monitor (displaying systolic and diastolic blood pressure, simplified version without large screen), sleep monitoring bracelet (displaying sleep duration, deep sleep / light sleep ratio);

Medical Auxiliary Equipment: Such as a small insulin pen (displaying remaining dose, injection times), portable fetal heart rate monitor (displaying fetal heart rate, giving pregnant women intuitive feedback, no complex waveform).

IV. Maker and Education: Entry-Level Color Display Teaching Tools

In the fields of maker development and electronic education, this module is an ideal choice for "low-cost color display entry-level", with the core value of lowering the learning threshold:

Maker Project Prototypes: Such as an intelligent flower pot (displaying soil moisture, watering reminder icons), mini weather station (displaying temperature, wind speed, weather icons), DIY electronic clock (displaying time, date, battery level, supporting color fonts), no need for complex drivers, SPI interface easy to interface with mainstream MCUs (such as Arduino, ESP32); Electronic Teaching Experiment: Applied to the "Embedded Display Principles" course, enabling students to quickly master TFT display drivers, SPI communication protocols, and image/text display logic. Compared to large-screen TFTs (such as 2.4-inch), it has lower costs and less damage risks, making it suitable for batch teaching use.

V. Automotive and Transportation: Auxiliary Information Display

In the aftermarket automotive market or small transportation devices, it is used for auxiliary information display for "non-driver" positions, meeting the requirements for small-space installation:
Automotive aftermarket components: such as mini tire pressure monitors (displaying individual tire pressure and temperature, attached to the dashboard), in-vehicle Bluetooth phone displays (displaying incoming numbers, call duration);
Small transportation devices: such as electric bicycle dashboards (displaying speed, remaining battery power, mileage, replacing traditional mechanical dials), shared bicycle smart locks (displaying unlocking status, remaining battery power, fault alerts).
Summary: Commonalities of Core Adaptation Scenarios
The purpose of this TFT module is essentially centered around "small-size requirements + low-complexity display + low-cost MCU integration" - when the scenario does not require a large screen (such as mobile phones, tablets), does not require ultra-high resolution (such as high-definition displays), but requires color display to enhance information readability, and the main control is a resource-limited MCU, it is an extremely cost-effective choice and is a typical solution for "small and beautiful color display" in electronic devices.
