Overview
A laptop’s screen shapes your whole experience — its panel type affects colours and viewing angles, while size affects portability and workspace. This guide explains the common screen technologies and sizes so you can pick the right display.
Key Takeaways
- Modern laptops use LCD/LED backlit panels — typically TN, IPS, or VA — or OLED.
- IPS offers the best colour and viewing angles for most users; TN is cheapest and fastest.
- OLED/AMOLED give the best contrast and colours but cost more.
- Screen size (measured diagonally) trades portability against workspace.
Panel Technologies
- LCD/LED — almost all laptops use LCD panels with LED backlighting (“LED” screens).
- TN (Twisted Nematic) — cheapest, fast response (good for budget/gaming), but weaker colours and viewing angles.
- IPS (In-Plane Switching) — excellent colour accuracy and wide viewing angles; the best all-round choice.
- VA (Vertical Alignment) — high contrast and deep blacks, with middling response times.
- OLED / AMOLED — per-pixel lighting for perfect blacks, vivid colour, and great contrast; premium and pricier.
How Screen Size Is Measured
Laptop screen size is the diagonal distance between opposite corners of the display, in inches (not the width). A 15.6" laptop measures 15.6 inches corner to corner.
Common Laptop Sizes
- 11.6" – 12.5" — very portable, light, best for travel and basic tasks.
- 13.3" – 14" — the sweet spot for portability and usability; popular for ultrabooks.
- 15.6" — the most common size; a good balance of screen space and portability.
- 17.3"+ — large, desktop-replacement laptops for gaming and creative work, less portable.
How to Choose
- For colour-critical work (photo/video), choose IPS or OLED with good colour coverage.
- For competitive gaming, a fast TN or high-refresh IPS panel helps.
- For battery life and portability, smaller 13–14" panels are ideal.
- For a desktop replacement, 15.6"–17.3" gives the most workspace.
Frequently Asked Questions
Problem: IPS vs OLED — which is better?
Solution: OLED has deeper blacks and richer colour; IPS is bright, accurate, and cheaper with no burn-in risk. Choose based on budget and use.
Problem: Is a bigger screen always better?
Solution: No — bigger screens add weight and reduce battery life. Balance workspace against portability.
Problem: What resolution should I get?
Solution: Full HD (1920×1080) suits most 13–15" laptops; consider QHD/4K for larger screens or detailed work.
Problem: Does refresh rate matter?
Solution: For gaming, yes — 120Hz+ is smoother. For everyday use, 60Hz is fine.
Conclusion
Match the panel and size to your needs: IPS or OLED for great visuals, TN for budget/speed, and a size that balances workspace with portability. Knowing these basics makes choosing your next laptop screen much easier.
