Screen & Display Repair Terms
The display is the most visible component of a laptop — and display faults are among the most common repairs. Know the difference before you walk in.
The light source behind a laptop LCD. Failure causes a completely black screen — but a faint image visible with a torch confirms the panel still works. Usually requires display assembly replacement.
Laptop runs (fans spin, keyboard lights up) but shows no image. Multiple causes: backlight, flex cable, GPU, or POST failure. Test with an external monitor first — if that works, the fault is in the display, not the board.
Liquid Crystal Display — the panel technology in most laptops. Requires a separate backlight. Backlight faults and cracked panel faults are different repairs with different costs. Always confirm which is the problem before agreeing to a quote.
In-Plane Switching — an LCD panel type with better colour accuracy and wider viewing angles than older TN panels. If an IPS panel is replaced with a TN during repair, colours and viewing angles degrade noticeably. Confirm the replacement type with your technician.
Organic Light-Emitting Diode — each pixel produces its own light. No backlight needed. Offers true blacks and vivid colours. More expensive to replace than LCD. OLED burn-in (permanent image retention from static elements) is a known issue on some models.
The ribbon cable connecting the screen to the motherboard through the hinge. Screen flickering that changes when you move the lid, or lines appearing at certain angles, usually points to a failing flex cable. Less expensive to replace than the full panel.
A permanently failed pixel showing as a fixed black, white, or coloured dot. Single dead pixels are cosmetic. Spreading clusters after a drop mean the LCD layer is cracking internally — replacement is needed before it worsens.
