This is the front outer cover glass lens of the Vivo X50 Pro.
“OCA” stands for Optically Clear Adhesive — a transparent adhesive film used for laminating the glass lens to the underlying display/touch module, ensuring there is virtually no air‑gap between the glass and the display. That helps maintain optical clarity, full touch responsiveness, minimal reflectance or ghosting.
A quality replacement part will either include the OCA film already bonded (i.e., “glass + OCA pre‑laminated”) or be glass that is ready for OCA lamination by a technician.
When choosing this type of replacement for the X50 Pro, look out for the following:
Model Compatibility: Specifically lists “Vivo X50 Pro” (or the exact variant) and that it’s “front glass + OCA film” or “glass + OCA bonded”.
Material & Quality: New glass (not used/refurbished), precise machining of cut‑outs (front camera punch‑hole, sensor region), correct curvature/edge profile (especially since the X50 Pro has a curved display) as the original lens.
Optical Clarity & Touch Performance: With OCA bonding, you should have minimal loss of brightness, no visible haze, distortions or ghosting; and the in‑display fingerprint sensor (if present) should function properly.
Bonding Quality / Installation Readiness: If it’s pre‑laminated with OCA, installation is simpler; if glass only (with OCA film to be applied), then you’ll need proper lamination equipment (vacuum press, clean environment) to avoid bubbles, dust ingress, edge lift.
Usage Scenario: The part is intended for “glass‑only” replacement — meaning that your underlying display/touch screen (AMOLED panel + digitizer) is functioning fine and you are replacing only the cracked/damaged outer glass lens.
Fit & Finish: Glass should align with the phone’s frame perfectly, edge sealing should be good (especially important on curved edges) so that dust or moisture don’t seep in after repair.
Return / Warranty Info: A reputable seller will either give a short “testing period” or guarantee that the part is brand new and unused. Many listings note “non‑returnable once installed”.
