Quality Control That Beats the Industry Standard
Most suppliers ship by sample. We ship by standard. Every JK screen is measured against published, strict benchmarks — so what you receive is consistent, batch after batch, country after country.
100% Tested
Total Quality Control Standard
Quality is not a single checkpoint — it is a system built into every stage, from incoming materials to the carton that reaches your door. Our TQC standard aligns with ISO 9241-307 and IEC 62341, and is enforced on 100% of production.
Incoming Material Control
Panels, ICs, flex cables and glass are verified to specification and compatibility-tested before mass production begins.
100% Functional Verification
Every single unit is powered on and tested — never sampled. Touch, signal and IC communication are confirmed on real test rigs.
Cosmetic & Grading Standard
Automated optical inspection plus human review. Screens are graded A / AA / AAA against defined defect limits.
Traceability & Warranty
Every batch carries a traceable code. A 12-month warranty and root-cause feedback loop keep standards rising.
4 Quality Control Levels
Four escalating control levels, each a gate that defective units cannot pass.
Incoming Inspection
Supplier panels, touch sensors, ICs and connectors are verified and compatibility-tested before entering the line.
Functional Testing
Each screen is powered on; display activation, touch response, signal transmission and IC communication are checked.
Visual & Cosmetic Grading
AOI cameras and trained inspectors catch dead pixels, mura, scratches, dust and fingerprints against strict limits.
Reliability & Aging
Burn-in, temperature/humidity, drop, vibration and ESD tests prove the unit survives real-world use before shipping.
Incoming Inspection
Materials and components verified against spec.
Functional Testing
Power, touch, signal and IC communication confirmed.
Display Performance
Brightness, color, contrast and uniformity measured.
Dead Pixel & Mura
Solid-color patterns reveal pixel and shading defects.
Aging & Burn-In
Continuous operation surfaces unstable components.
Reliability Testing
Temperature, humidity, drop, vibration and ESD.
Grading & Packaging
Graded, coded and sealed in drop-tested cartons.
Screen Test Process
The checks behind every “100% tested” claim — what happens when a screen reaches our test bench.
Display & Brightness
Luminance (cd/m²), contrast ≥1000:1, viewing angle and response time measured with photometric equipment.
Color Accuracy
sRGB / DCI-P3 gamut, ΔE≤2 color error, color temperature 5000–9300K calibrated per unit.
Touch Response
Multi-touch, gesture recognition, linearity error ≤1.5%, report rate ≥120Hz across the whole surface.
Pixel & Mura
Solid white/black/red/green/blue patterns reveal dead, white and dark pixels; mura scan catches uneven shading.
Fit & Structure
Frame tolerance, connector integrity, flex-cable seating and IC bonding verified for perfect fitment.
Environment
High/low temperature, 85℃/85%RH humidity, vibration, 1m drop and ESD resistance before carton sealing.
