The TBK 288HA is a heated vacuum screen separator that lifts the glass layer off an LCD or OLED panel. It is used by refurbishers to separate cracked glass from a working display so the panel can be reused or re-laminated. Digi4u supplies the TBK 288HA and the tools around it.

About this guide: based on hands-on bench testing and repair experience; confirm official specifications with the supplier before ordering.
What the TBK 288HA does
The separator holds the phone or display on a heated platform and uses a vacuum pad to lift the glass. Heat softens the OCA optical adhesive that bonds the glass to the panel, and the vacuum lifts the glass cleanly instead of prying it with blades.
The result is a panel that can be cleaned, re-bonded to new glass and returned to service. That is the core of screen refurbishing, and it is why the separator sits at the centre of a refurbishing bench.
How heated vacuum separation works
The process depends on even heat and a controlled lift:
- Place the screen on the heated platform and set the temperature.
- Align the vacuum pad over the glass.
- Start the vacuum so the pad grips the glass evenly.
- Lift the pad slowly as the OCA softens.
- Remove the glass and clean the remaining adhesive from the panel.
Even temperature matters more than speed. If the heat is too low, the OCA tears; if it is too high, the panel or its polariser can be damaged.
What it can and cannot fix
| Job | Result with a separator |
|---|---|
| Cracked glass on a working panel | Glass removed, panel reusable |
| Broken LCD or OLED panel | Separation possible, panel still dead |
| Digitizer damage | Panel and glass may both need replacing |
| Deep frame damage | No separator repairs a bent frame |
The machine only separates layers. It does not repair a dead panel, replace the backlight or fix touch damage. Refurbishers still need cleaning, lamination and bubble-removal steps after separation.
Bench use cases
The main use case is converting a cracked-screen phone into a refurbished unit by saving the original panel. It is also used to remove glass from screens for parts harvesting, and to rework panels where the digitizer needs a clean separation before testing.
For shops that buy cracked phones in volume, the separator changes the economics: a working panel that would have been scrapped can become a saleable screen again.
Who should buy one
The TBK 288HA suits refurbishers and repair shops that handle cracked screens in volume. A shop doing occasional single repairs can rely on manual separation, but the vacuum separator pays off once the bench handles several screens a week.
The refurbishing line around the separator
The TBK 288HA is one station in a refurbishing line, and the stations around it decide whether the separated panel becomes a sellable screen. After separation, the panel needs cleaning to remove the OCA residue, a new glass layer, lamination under vacuum, and a bubble-removal step before testing. A separator without that line produces panels that cannot be finished.
The practical order on a refurbishing bench is: separate, clean, inspect, laminate, degas, test. The inspection step matters most, because a panel with dead pixels or a damaged polariser is not worth re-laminating. The shop should check the panel before spending time on the lamination steps.
For a shop starting refurbishing, the line can be built in stages: the separator and a cleaning kit first, then a laminator, then the degassing machine. Each stage adds a sellable step, and the test at the end of every stage protects the work already done.
A separator is one station in the refurbishing line, and the cleaning and lamination steps decide the finished screen. See the screen repair tools range at Digi4u for the stations that follow separation, and build the line before the volume arrives.

Digi4u workshop notes
Our bench rule: heat the platform, not the hurry. The OCA releases when it is ready, and a slow vacuum lift saves more panels than a fast one.

Conclusion
The TBK 288HA separates glass from working panels with even heat and a vacuum lift, which turns cracked-screen stock into reusable displays. See the screen separator and refurbishing tools at Digi4u.
Frequently Asked Questions
What is a screen separator machine?
It is a machine that separates the glass layer from an LCD or OLED panel, usually with heat and vacuum, so the panel can be reused.
Can the TBK 288HA fix a broken screen?
It can separate the broken glass from a working panel. The panel then needs cleaning, new glass and lamination to become a finished screen.
Is a heated separator better than manual separation?
For volume work, yes. Heat and vacuum give a more even, controlled lift than blades, which reduces panel damage.
