What is a good screen?

With the development of the times
The continuous iterative upgrading of LCD screens
Various types of products have entered thousands of households

This is inseparable from the efforts of engineers and other departments to allow us 

to enjoy good LCD screen services
Today, I will tell you the story behind the Zhanhui optoelectronic screen

Production workshop

Starting from the basic theoretical construction, the production and manufacturing technology of LCD screen integrates the technical achievements of various disciplines such as optics, microelectronics, chemistry, electromechanical, and materials, showing the characteristics of multidisciplinary integration. Therefore, the required production machines have high technical requirements and strict workshop construction requirements.

From the perspective of technological flow, although LCD screens are very simple from the outside, their manufacturing process is very complex and fine. It includes a series of process flow and control technologies such as graphic production, orientation layer production, empty box production, liquid crystal injection, COG binding, etc. It is necessary to combine these things tightly, and its difficulty is compared to food, which is no less meticulous but delicious than "Wensi Tofu" and "Buddha Jumping Over the Wall".

From the perspective of manufacturing, LCD screen production requires advanced production equipment and clean production workshops, as well as a large number of workers with long-term production experience and a large number of technical teams with professional knowledge in the fields of optics, semiconductors, electronics, materials, chemistry, chemical industry, automation control, etc. and have rich practical experience. Screen production is inseparable from the cooperation and promotion of all departments, and all parties work together to make a good screen.

Technical requirements

The production process of Zhanhui Optoelectronics can be roughly divided into three sections: front, middle and back, and each production section is a puzzle piece to achieve a good screen. But the production of an LCD screen is actually far more than that, if you count all the large and small processes, there are as many as 300 processes and multiple testing steps, and behind each good screen is a lot of hard work!

The process flow of the front section of the LCD screen, the technology required for screen production, requires the cleanliness of the operating environment to be 1,000 levels dust-free, the temperature is maintained at about ±23 degrees, and the working humidity ± 55RH.

The process flow of the middle section of the LCD screen should keep the operating environment clean and dust-free, constant humidity and constant temperature, and at the same time, it should focus on the pre-curing temperature of the frame adhesive, the uniformity of the distribution of silicon powder, the density of the powder spray, and whether there is agglomeration. At this time, the screen has begun to take shape, and grasping the curing time is not only to achieve function, but also to pursue the appearance of the screen, the integrity of the fit, so that it can also have an extra layer of aesthetic color in practical situations.

The process flow of the back section of the LCD screen, the so-called hundred miles is half ninety, the final step can not be relaxed, the key points to pay attention to are the vacuum of the filling machine, alignment, N2 flow, LC pollution, leveling pressure and other aspects. At this point, the overall screen production has come to an end, but the service purpose of Zhanhui Optoelectronics is not over, we always believe that only by handing over the screen to the user until satisfaction, a good screen can be considered a real sense of production.

Product packaging is the last line of defense for the finished screen, and its packaging quality determines the quality of the finished product in the hands of the customer. In order to ensure the original state and quality of the goods, the technical means adopted by Zhanhui Optoelectronics for the products are not damaged or affected during transportation, flow, trading, storage and use. Ensure the integrity of the quality and quantity of the goods themselves, prevent a series of accidents in loading and unloading, handling, stacking, meticulous support measures for soft materials, and tailor-made packaging of products of different sizes to ensure that the products reach customers in a timely and accurate manner.
