LCD
Liquid Crystal Display — the panel technology used in most laptops. Understanding LCD faults helps you know what’s actually being repaired and why the cost varies.
LCD is the dominant screen technology in laptops. It works by using a backlight to shine light through layers of liquid crystals and colour filters to produce an image.
Because LCD panels rely on a separate backlight, they have two distinct failure modes: the backlight can fail (causing a black screen with faint image visible under torchlight), or the panel itself can crack (causing distorted colours, lines, or a shattered display).
| LCD | OLED | |
|---|---|---|
| Light source | Separate backlight | Each pixel self-lit |
| Black levels | Dark grey | True black |
| Burn-in risk | None | Yes, over time |
| Replacement cost | Lower | Higher |
- Cracked panel — visible crack lines, ink bleed, or shattered glass after impact
- Backlight failure — screen goes black but laptop keeps running; faint image visible with torch
- Horizontal or vertical lines — damaged flex cable or panel failure
- Colour distortion — washed-out or inverted colours; panel or cable fault
- Flickering — intermittent, especially when lid is moved; usually the flex cable
Is LCD or OLED better for a laptop?
OLED offers better contrast and more vivid colours. LCD (especially IPS) is perfectly capable for everyday use, costs less to replace, and has no burn-in risk. For most users, a good IPS LCD is the more practical choice.
Can a cracked LCD be repaired?
No — the panel must be replaced. Cracks spread over time, so replacement sooner rather than later keeps costs predictable.
Will my replacement screen be the same quality as the original?
It should be — always confirm the panel type (IPS vs TN) and resolution with your technician before the repair.
