In the quality inspection and control of LED transparent display products, aging inspection is a very important and essential link. It is also the last inspection link in the production inspection of LED transparent displays and an important guarantee for the quality of LED transparent displays. LED products can improve their performance after aging and contribute to stable performance in later use. LED aging inspection is a measure adopted based on the characteristics of the product's failure rate curve, that is, the bathtub curve, in order to improve the reliability of the product. Its main process only includes the following three points:One: Check1. Check that all the above box modules are installed correctly;2. Check whether there are short circuits or mixed connections in the electrical system;3. Check whether the module installation is smooth and whether the seams are neat;4. Check whether the appearance is intact and whether there are any bumps or scratches;Two: Light up aging1
The transparent screen is a new type of display device that has the advantages of being lightweight, beautiful, and easy to install. It has been widely used in commercial advertising, exhibition displays, traffic instructions and other fields. However, as an electronic device, the performance of transparent screens is greatly affected by temperature. Especially in high-temperature environments, problems such as thermal deformation and distortion may occur. Therefore, studying the heat treatment performance of transparent screens is of great significance to improve their stability and service life.1. Introduction to the heat treatment performance of transparent screensThe heat treatment performance of the transparent screen refers to its stability and reliability in high temperature environments. Specifically, the heat treatment performance of transparent screens includes the following aspects:1.Temperature resistance: Can the transparent screen withstand high temperature environments a
1. Choose high-quality materials: The material of the transparent screen has an important impact on its recoverable performance. Common transparent screen materials currently on the market include polycarbonate (PC), polymethyl methacrylate (PMMA), etc. Among them, PC material has high scratch resistance and impact resistance, and is one of the main materials for making transparent screens. In addition, PMMA materials also have better recoverability properties, but the price is higher.2. Using special treatment technology: The surface of the transparent screen adopts special treatment technology to effectively improve its scratch resistance and impact resistance. For example, electroplating oxidation technology can be used to form a layer of high-hardness oxide protective film on the transparent screen surface, which can effectively resist scratches and wear; spraying nano-anti-fingerprint technology can be used to form a nano-level anti-fingerprint coating on the transparent screen su
The aging of LED transparent display screen is a procedure that must be carried out after each display is completed. If the LED transparent display screen has not been aged, whether it is indoor, outdoor, single color, two colors or full color, it will be classified as unfavorable. Qualified product ranks. So why does the LED transparent display undergo aging testing? How is aging done? What specific process steps do you need to go through? The editor below will answer these questions one by one, hoping to help everyone better understand the LED transparent display.Do transparent LEDs need to be aged? Why LED display products can improve their performance after aging and help stabilize their performance in later use? LED transparent display aging test is a very important link in product quality control. LED aging test is a countermeasure taken based on the characteristics of the product's failure rate curve, that is, the bathtub curve, in order to improve the reliability of the product
Out-of-control pixels on full-color LED displays is a relatively common problem. What is the cause of this phenomenon and how to solve it? Today I will analyze it with you.Analysis of the causes of out-of-control pixels in full-color LED displaysThe pixels of the LED display screen are out of control, which means that the smallest imaging unit (pixel) of the display screen is not working properly. The ratio of the number of out-of-control pixels to the total number of pixels in the entire screen is called the "out-of-control pixel rate of the entire screen." There are two types of pixel out-of-control modes. One is a blind spot, which is a blind spot. It does not light up when it needs to be bright, which is called a blind spot. The other is a constant bright spot, which keeps lighting up when it needs to not light up. This is called a blind spot. It's always a highlight.Generally, the common LED display pixel compositions are 2R1G1B (2 red lights, 1 green light and 1 blue light, the s
1. Commercial billboards: Transparent screens can be used in the production of commercial billboards. Its good scratch resistance and impact resistance ensure that billboards can display information stably for a long time and enhance brand awareness and reputation. For example, it is widely used in shopping malls, hotel lobbies, airports and other places.2. Exhibition display stand: The transparent screen can be used as an exhibition display stand, which provides a better display effect for exhibits with its lightweight and beautiful features. Due to its good restorability, it can be used normally in various harsh environments to ensure the smooth progress of exhibition activities. For example, it is widely used in museums, art galleries, science and technology museums and other places.3. Traffic signs: Transparent screens can be used in the production of traffic signs to display information with high definition and brightness, improve drivers' awareness and reaction speed of road info
The transparent screen is a new type of display device that has the advantages of being lightweight, beautiful, and easy to install. It has been widely used in commercial advertising, exhibition displays, traffic instructions and other fields. However, due to long-term use and the influence of external factors, transparent screens may have some problems, such as poor recoverability, color distortion, reduced brightness, etc. Therefore, improving the recoverability performance of transparent screens has become one of the focuses of research.1. Introduction to the recoverable performance of transparent screensThe recoverability performance of a transparent screen refers to its ability to return to normal display after being damaged during use. Generally speaking, the recoverable performance of transparent screens includes the following aspects:1.Scratch resistance: The surface of the transparent screen adopts a special treatment process, which can effectively resist physical damage such
1. The most important thing when installing is to strictly follow the design drawings and other technical data requirements. During the laying of cables, basic civil engineering, and construction of steel structural frames, professional technicians will issue corresponding drawings and pass the review of relevant departments. The specifications and dosage of materials must be selected as required to ensure the safety and reliability of the display.2. Before construction, isolation belts, protective nets, safety warning signs, etc. must be pulled up, and safety protection equipment must be prepared to ensure safe production in terms of awareness and equipment. Handle the product with care during transportation and take anti-static measures to ensure that the product is not damaged due to external reasons.3. When assembling the box, use hoisting facilities to lift the box to the steel frame, fix it row by row according to the box number, complete the tightening after adjustment, and then
