Application Fields of Small-Sized Color Screens
Small-sized color screens, known for their compact size, relatively
low power consumption, and intuitive display of information, are
widely used across various fields of modern electronic devices.
1. Consumer Electronics
Smart Wearables: Smartwatches and fitness trackers are the most typical
applications. They display time, notifications, heart rate, fitness
data, etc.
E.g., Apple Watch, Mi Band.
Secondary Smartphone Displays: Some foldable phones or specially designed phones feature a small
color screen on the outer shell for showing time, notifications, or
quick camera control.
Portable Gaming Devices: Such as handheld game consoles and retro game emulators, where the
small color screen is the core display interface.
Wireless Earbuds Charging Case: Some high-end wireless earbud cases integrate a small screen to
show the battery level of the earbuds and the case, as well as
connection status.
Digital Cameras: The viewfinder and the main rear screen on cameras are critical
applications for small color screens, used for photo preview,
playback, and menu navigation.
2. Industrial and Medical Equipment
Industrial Handheld Terminals: Used in warehousing, logistics, retail, and manufacturing for
barcode scanning, inventory management, and data collection. Their
screens need to display text and graphic information clearly.
Medical Monitoring Devices: Portable devices like glucometers, blood pressure monitors, pulse
oximeters, and portable ECG machines use small color screens to
display measurement results and waveforms clearly and intuitively.
Industrial Control Systems: Serve as compact Human-Machine Interfaces for displaying equipment
status, parameter settings, and operational instructions. E.g.,
control panels for CNC machines, displays on test and measurement
instruments.
3. Smart Home and IoT
Smart Home Control Panels: Small color screens integrated into smart speakers, thermostats,
or dedicated control panels for managing lights, climate, security
systems, etc.
Home Appliances: Displays on high-end refrigerators, washing machines, coffee
makers, and air purifiers show operational status, modes, and
settings.
Smart Locks: Smart locks with small color screens can display lock status,
battery level, and often integrate a video feed from a doorbell
camera.
4. Automotive Electronics
Rear Seat Entertainment Screens: These are extensions of the central infotainment system, providing
independent entertainment and control for rear passengers.
Instrument Cluster Displays: Used in motorcycles, electric vehicles, or entry-level cars,
replacing traditional analog gauges to show speed, RPM, mileage,
etc.
Auxiliary Automotive Devices: Such as displays for backup cameras and dash cams.
5. Other Emerging Fields
AR/VR Devices: Act as part of the near-eye display system, requiring extremely
high specifications for size, resolution, and refresh rate.
Drone Controllers: Display the real-time First Person View video stream, flight
parameters, and map information from the drone.
Portable Media Players: High-fidelity audio players require screens for track selection
and system configuration
