How to solve the dark spot on LCD screen?

With the progress of science and technology, LCD is more and more popular. However, the inherent and inevitable shortcomings of LCD have also been paid attention to. When it comes to LCD black spots, many people may not understand. Today, I will teach you how to look at black spots. I hope it can help you.   What is the dark spot of LCD? In fact, dark spot is more hidden than bright spot and bad spot, but its influence on use is far greater than bad spot. Sometimes on some screens, there will be some patches that are not very big. The black small class is as big as the soybean, and the big class may be as big as the thumb. Different from the bright and dark spots, the dark color system is only partially dark, which is not easy to find from the front, but only from the side.   The main reason for the formation of dark spots is that the external force has been squeezed for long time. We think that it is probably due to improper handling in the transportation process. LCD screens with black dots are usually hard to find on the front and more obvious on the side (just like the test perspective).We suggest that when you buy LCD, you should not only look at the bad points of the screen, but also look at the surface of the screen from multiple angles, and set the screen to white. If you find

How Digital Signage Works?

How Digital Signage Works: Understanding the Key Components and Benefits Digital signage has become an essential component in modern marketing, providing businesses with an effective way to engage with customers, deliver engaging content, and drive sales. In this article, we’ll explore how digital signage works, looking at the key hardware components, content creation, and management process, connectivity, and the benefits it provides businesses. I. Introduction Digital Signage is a technology that refers to electronic displays that show images, videos, or other types of content. It is a visual communication tool that can be used to convey information, branding messages, or advertising campaigns. This form of marketing has revolutionized the way businesses communicate with customers, providing them with an interactive, immersive experience with their brands. II. Hardware Components Digital signage systems comprise three fundamental components: displays, media players, and content management software. Displays come in various types, including LED or LCD screens, video walls, interactive displays, and kiosks. Media players include set-top boxes, compute sticks or embedded boards that power the displays. The content management software helps manage and schedule the display content, ensuring it is always up-to-date. III. Content Creation Creating visually appealing content is crucial in digital signage. Graphics, animations, and videos effectively communicate messages to your audience. Professional design software tools such as Adobe Illustrator and Photoshop can be used to create stunning motion graphics, while software such as After Effects can help create high-quality video content. IV. Content Management Content management software allows you to remotely manage,

What is the function of LCD Polarizer?

Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm.
