What to Consider When Choosing LCD Screen?
LCD screen selection should not be made only by price; it should be made according to usage area, performance and technical specifications.A wrongly selected LCD panel both increases cost and decreases performance of your device.To choose the right LCD, you need to know 4 critical criteria.Selection Criteria - 4
Critical Points
1. Resolution
The higher the pixel density, the clearer the image. Choose resolution suitable for your application. While 800x480 may be enough for industrial HMI, 1920x1080 may be required in medical devices.
2. Viewing Angle (Wide Angle - 178°)
Color and brightness must be preserved at wide angle. For kiosk, POS, industrial panel requiring multi-directional viewing, 178° IPS is mandatory.
3. Power Consumption (Low Power)
Low power consumption provides long battery life. Most important criterion in portable, battery-powered and IoT devices.
4. Operating Environment (Temperature)
-20°C / +70°C thermal resistance.
For industrial and outdoor applications, panel with wide temperature range must be selected. Standard 0-50°C panels break outdoors.
How Does LCD Panel Cross-Section Work?
An LCD panel consists of 6 layers:
Protective Glass / Polarizer → Color Filter (RGB) → Liquid Crystal Layer → TFT Layer / Electrodes → LED Backlight → Diffuser & Reflector LayerPanel works on principle of LED backlight and liquid crystal directing light.Which Technology for What?TFT LCD → Standard IndustrialEconomical and common useFast response timeStandard viewing angleWhere used?

Wrong selection increases cost and decreases device performance. Before making selection, be sure to clarify your usage area and operating environment.Our advice: If you are not sure, consult Karina Elektronik technical team, we will choose the most suitable panel for you.
