In the past year, the team has jointly solved 7 technical challenges, including reducing standby power consumption of LCD advertising machine display screens, optimizing heat dissipation structures, and improving image uniformity.
Among them, by improving the backlight module design, the average power consumption of the 55 inch LCD advertising machine display screen was reduced from 185W to 162W, a decrease of 12.4%.
By optimizing the heat dissipation duct, the operating temperature of key components has been reduced by 8 ℃, significantly improving product reliability.
Regarding the identified issues, Ruiguan adopts an 8D report format for tracking and management. Each LCD advertising machine display screen issue will have a clear responsible person, root cause, temporary measures, and long-term countermeasures, and specific completion time nodes will be set.
In the past year, Ruiguan has issued a total of 9 8D reports to the LCD advertising machine display screen supplier, all of which have been rectified within the specified time.
05 Technology Outlook: Quality Upgrade for the Future
With the development of commercial display technology, Ruiguan is working with LCD advertising machine display screen suppliers to jointly develop a new generation of advertising machine products. During the factory inspection, the technical teams of both parties had in-depth exchanges on topics such as high brightness outdoor display technology for LCD advertising machine display screens, low reflection touch screens, and energy-saving mode optimization.
The data shows that the annual growth rate of demand for high brightness outdoor advertising machines with LCD display screens in the market is 18%, while the growth rate of demand for energy-saving products is as high as 25%.
To cope with this trend, Ruiguan plans to increase the average energy efficiency of its LCD advertising machine display screen products by 15% in the next year, while also increasing the peak brightness of outdoor models to over 2500 nits.
Based on the results of this factory inspection, the comprehensive score of the supplier is 88.7 points, and they will continue to maintain their A-level supplier qualification.
Zhang specifically pointed out in the summary report that the supplier's continuous improvement in process control and data analysis is commendable, but there is still room for improvement in the pre research of new technologies.
At the summary meeting after the factory inspection, Mr. Zhang emphasized that "quality is not determined by final inspection, but by carefully constructed results at every stage." Ruiguan's comprehensive supplier management system ensures that every stage of the LCD advertising machine display screen, from raw materials to finished products, is under control.
This rigorous quality culture has been translated into market recognition - according to the latest industry data, the customer satisfaction rate of Ruiguan advertising machine products is 96.2%, with a repair rate of less than 1.5%, establishing a good brand reputation in the field of LCD advertising machine display screens and commercial displays.
By continuously optimizing supply chain quality control, Ruiguan is providing reliable high-quality display solutions for LCD advertising machine display screens to a wider market.
