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.
