Digitiser
The touch-sensitive layer — separate from the display panel
The digitiser is the touch-sensitive layer bonded to the display panel. It converts finger position into digital coordinates the processor can read. If the screen displays a perfect image but registers no touch input — or registers incorrect touches — the digitiser is at fault, not the display itself. On Galaxy Z Fold models, both the outer and inner screens have separate digitisers.
Why It Matters For Your Repair
Correctly identifying whether a fault is the display or the digitiser determines the repair cost. A digitiser-only fault on some Samsung models can be repaired cheaper than a full panel replacement. If ghost touch persists after a new screen is fitted, the fault may be the Touch IC on the logic board — not the digitiser.
Display vs Digitiser — Key Difference
Black patches, wrong colours, lines — but touch still works.
Image is perfect — but touch doesn’t respond or ghost touches appear.
