Why Can We Always Ensure Excellent Quality

Quality Control

Founded in 1992, Sealan brand Group is a production-oriented enterprise engaged in the research and development, production, sales and technical services of computer and digital products.In 2013, the group invested and established Shenzhen Yundacheng Technology Co., LTD., which mainly produces all-in-one computers, notebook computers, TFT-LCD monitor and digital intelligent advertising machines. At present, the group has 3 standardized production and manufacturing bases in its headquarters in Shenzhen.The development of the company so far, The goods through the global, in the vast majority of cities around the world to establish a marketing network, with thousands of agents signed. adheres to the enterprise spirit of " The morality of business is the same as that of human beings" and the management philosophy of "people-oriented", focuses on product quality, technology and after-sales service, and always adheres to providing users with better cost-effective information products, And always adhere to provide users with better cost-effective information products, and actively promote the development of the global information industry.

Here, how did a high quality computer come out?

High-quality components make up a computer system

SEALAN selects products provided by brands or manufacturers with good quality and good reputation. These parts and products not only undergo a series of strict quality inspections before they leave the factory, but after they come to SEALAN, they must also undergo a quality review by SEALAN engineers through the original factory burn-in program to ensure excellent quality.

Then is the second system self-test process, which is basically similar to the first time. The difference is that LCD bright spot detection will be performed at this stage. SEALAN Computer promises consumers that "LCD has no bright spots". At this stage, professional engineers will be selected to personally test the LCD screen of each computer to ensure that no bright spots irritate consumers' eyes.

Next is the extremely complicated software and hardware compatibility testing process.

Sand and dust test: In response to the needs of laptop users, this test was developed to confirm the reading efficiency of the laptop's reading head, and confirm that the related connectors and fans of the system are working properly.

Electricity test: Conduct specification tests for various power characteristics of various manufacturers' existing related products, including the confirmation of product power consumption and the effective confirmation and improvement of various effects of power quality on the product.

The product that passes this test must be a good work that can still operate normally when the power supply is unstable or the current is disturbed, such as a sudden lightning that causes a huge change in the current and a high voltage of 15,000V. .

Chromatic aberration test: In order to achieve the best appearance of the product, the instrument confirms the spectral characteristics of the material.

SEALAN uses spectral analysis and three primary color analysis to ensure that the appearance of the notebook computer reaches the preset target and protect the rights and interests of consumers.

LCD display test: The unique high-voltage conversion driver circuit design can effectively extend the life of the backlight board, and can also reduce the lowest range of brightness from the usual 15% in the industry to 3%.

This is another measure taken by SEANLAN to ensure the quality of LCD monitors in laptops. Users can easily enjoy high-quality LCD displays even under various illuminance environments.
