Applications of 5-inch HDMI Display

5-inch HDMI displays (mostly with touch function) are characterized by small size, portability and plug-and-play. They are mainly used in five scenarios: embedded development, portable secondary screen, smart home, industrial/automotive, and portable entertainment.

Embedded Development (Most Popular)

• Main display for Raspberry Pi / development boards: for system debugging, code running and terminal display

• Portable terminal / data acquisition: sensor data, serial logs, status monitoring, small instruments

• Open-source projects: RetroPie game consoles, Kodi media centers, 3D printer / CNC control screens

Computer / Office Extension

• Secondary screen for laptops / desktops: monitoring CPU/RAM, clock/calendar, chat/email, shortcut control panel

• Industrial control / server monitoring: real-time equipment room status, network traffic and log viewing

Smart Home / Central Control

• Whole-house control panel: control lighting, air conditioning, curtains, security and scene linkage

• Smart speaker / gateway screen: visual voice interaction, weather, news and schedule display

Industrial / Automotive / Portable

• Industrial HMI / equipment panel: small device operation, parameter setting, status display

• Automotive / RV secondary screen: reversing image, driving data, multimedia playback

• Outdoor / mobile devices: drone video transmission, portable oscilloscopes, field debugging terminals

Portable Entertainment

• Handheld / game console extension: portable small screen for Switch, PS5, Xbox

• Portable audio & video: connect to mobile phones, tablets or TV boxes for outdoor video viewing

Key Advantages

• Plug-and-play: HDMI + USB (touch), driver-free for Windows / macOS / Linux / Raspberry Pi

• Small size: about 12×9 cm, easy to embed and carry

• Optional touch: 5/10-point capacitive touch, replacing mouse and keyboard

• Low power consumption: suitable for battery-powered applications (power bank compatible)
