OLED-coated backplane

Deposit a normal-polarity reflective-anode RGB top-emission OLED through separately installed RGB/common-layer masks on the same incoming LTPO backplane. Source-checked architectural correction; critical whole-node chemistry/interface research remains unresolved.

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Deposit selected organic transport/emitter stack and electrodes

Deposit selected organic transport/emitter stack and electrodes

Inventory is a hypothesis; handling, waste, protection, calibration, quantities, losses and suitability are not completely identified.

Making outline

  1. Deposit a normal-polarity reflective-anode RGB top-emission OLED through separately installed RGB/common-layer masks on the same incoming LTPO backplane.
  2. One base glass travelsS0->S1->S2->S3->S4; second prefrittedlidL0 separate. Track actual source, installed pattern, transfer, calibration, controls and initial/recurring witness/service charges.
  3. No full research completion or physical/final material acceptance while B01-B03 remain.
