FAQ - Frequently Asked Questions - How to choose the right display for an embedded application
Intro
Display selection for embedded products depends on readability, interface, size, brightness, power consumption, temperature range, touch requirements, mechanical integration and lifecycle.
Industrial and professional products often need longer availability and more robust specifications than consumer displays.
Key technical selection criteria
Evaluate:
- display technology
- size
- resolution
- brightness
- contrast
- viewing angle
- interface
- touch option
- power consumption
- operating temperature
- backlight lifetime
- mechanical dimensions
- availability and lifecycle
Display technologies
Common options include:
- TFT LCD
- OLED
- monochrome LCD
- e-paper
- segmented displays
Each technology has different strengths in brightness, power consumption, viewing angle, lifetime and cost.
Interface selection
Check processor support for:
- SPI
- RGB
- LVDS
- MIPI DSI
- HDMI
The interface affects bandwidth, PCB complexity, cable length and software support.
Environmental requirements
For industrial use, check:
- operating temperature
- vibration
- humidity
- sunlight readability
- backlight lifetime
- cover glass
- sealing
- touch operation with gloves
Common mistakes
- choosing only by size and resolution
- ignoring brightness requirements
- not checking interface compatibility
- underestimating backlight lifetime
- forgetting operating temperature
- selecting a display with short lifecycle
- not testing readability in the final enclosure
Decision checklist
Before selecting a display, define:
- viewing distance
- indoor or outdoor use
- required brightness
- interface compatibility
- touch requirements
- available space
- power budget
- temperature range
- product lifetime
- supplier availability
