Why Quality Control Matters for Digital Signage?

As a digital signage manufacturer with 18 years of experience, VETO understands that for most customers, the primary concern is not price, but rather product stability and quality. Common concerns among customers include: black screens, screen flickering, instability during prolonged operation, and high after-sales maintenance costs. With VETO, you don’t have to worry about these issues. We implement a rigorous, multi-stage quality control system to comprehensively ensure product quality from the source through to shipment.

During product assembly, VETO assigns nine quality inspectors: one is responsible for raw material inspection; five in-line inspectors monitor the production process; two inspectors conduct aging tests; and one inspector performs final shipment inspection. All products must pass every stage of the inspection process before they can be packaged and shipped.

Quality Inspection Process

1, Raw Material Inspection

VETO select commercial-grade panels from LG or BOE and conduct rigorous inspections of the motherboard, power supply, and key components.

2, Assembly Process Inspection

Each production step is monitored in real time by dedicated personnel to ensure the assembly process is accurate and error-free.

3, Full-Unit Functional Testing

Comprehensive testing of the entire unit, including display performance, touch functionality, audio output, and system stability.

4, Aging Test

All products undergo 24–72 hours of continuous operation testing to simulate real-world usage conditions, identify potential issues in advance, and ensure long-term stable operation.

5, Pre-Shipment Inspection

Prior to shipment, a final inspection is conducted on the product’s appearance, structure, and packaging to ensure that every unit meets high-quality standards when delivered to the customer.
