Specification control
Approved drawings and critical parameters provide the shared reference for purchasing, production and inspection.
Quality and supply control
A good first sample must become repeatable production.
Quality begins with a clear specification, continues through material and process checks, and stays active through packaging, change control and lifecycle communication.
Inspection criteria and validation responsibilities are confirmed for each project. Chenxin supplies the display component, while the customer validates the complete product system.
Quality reference
Control the approved requirement—not an undefined idea of “good.”
Cosmetic, optical, electrical and mechanical acceptance should be written into the project reference so both sides evaluate the same result.
- Approved drawing and revision
- Critical material and parameter list
- Appearance and functional criteria
- Packaging and shipment requirements
Control framework
Six controls that support repeat supply.
The exact inspection method depends on display technology, customer requirements and the approved sample.
Incoming inspection
Project-critical glass, panels, ICs, polarizers, backlights, FPCs and connectors are checked against defined requirements.
Process control
Assembly conditions and in-process checks are defined around the display construction and customer appearance limits.
Optical and functional checks
Display appearance, image function, backlight and selected electrical parameters are reviewed at agreed control points.
Final inspection and packaging
Final checks and protective packaging are aligned with display fragility, handling and shipment conditions.
Change and lifecycle communication
Revision, forecast, material change and PCN expectations remain part of the ongoing supply discussion.
Validation ownership
Component checks and system validation are different.
Chenxin checks the display component against the confirmed specification. The customer or ODM validates the controller, enclosure, sealing, EMC, certification and complete product performance.
Chenxin display scope
Component confirmation
- Drawing and critical dimensions
- Display function and appearance
- FPC, connector and interface definition
- Agreed inspection and packaging
Customer / ODM scope
Complete-system validation
- Controller and power-system behavior
- Enclosure, sealing and mechanical stress
- EMC, safety and market certification
- Final-use environmental testing
Plan long-term supply
Make change control part of the first design review.
Forecast, approved materials, PCN expectations and revalidation steps are easier to agree before mass production begins.
