LED display, as an emerging visual medium, has experienced rapid development alongside the advancement of large-scale integrated circuits and computer technology. Unlike traditional display methods such as colorful neon signs, pixel tube TV walls, and four-color magnetic flip boards, LED display represents a new generation of digital signage. It has gained widespread adoption due to its numerous advantages, including high brightness, excellent dynamic image performance, low failure rate, energy efficiency, long lifespan, diverse content support, rich visual effects, and a high cost-performance ratio. Its versatility makes it suitable for use across various industries, especially in public institutions and spaces where clear, impactful visual communication is essential.
**1. Screen Body**
The screen body is composed of LED light-emitting diodes and control circuits that receive signals from the control line. These signals are generated by a computer and used to drive the LEDs to emit light. The entire display consists of unit panels with identical structures, which can be interchanged for easy installation and maintenance. Customers can customize the size of the display by combining an appropriate number of unit panels.
**2. Computer and External Devices**
The content shown on the screen is created and processed on a computer before being transmitted through cables to the display. External devices like scanners allow users to input images, patterns, or even handwritten text directly into the system.
**3. Video Peripherals**
Video content, such as live TV, VCDs, video recordings, or camera feeds, can be displayed on the screen via video peripherals. This allows for real-time transmission of dynamic visuals.
**4. Audio Equipment**
When connected to amplifiers and speakers, the display can play background music and synchronize audio with video content. This enhances the overall experience, making it more engaging and immersive for viewers.
**5. Communication System**
All components—such as computers, video devices, and audio equipment—are connected to the central system. This ensures a clear, organized wiring setup that is easy to install, operate, and maintain.
**6. Computer Network**
The system supports remote control through a computer network, enabling users to manage the display from a distance.
**Key Features**
- Supports national standard two-level Chinese characters (including English), with multiple font options (Song, Imitation Song, Shu Shu, Lishu, Weibei, Yao, and traditional) and adjustable sizes (from 16 to 72 points).
- Allows scanning of images, patterns, and even handwritten text using external scanners.
- Can display real-time video from TVs, VCRs, laser discs, and cameras, while also showing charts, animations, and other graphics simultaneously.
- Enables real-time display of computer-generated content, such as stock quotes, financial data, weather forecasts, and news updates.
- Offers various animation modes, including top-down, left-right, center expansion, moving shutters, and marquee effects.
- Each image can be set to display for a specific duration and automatically switch to the next.
- Supports windowed displays, allowing parts of the computer monitor to be shown on the LED screen.
- Each pixel on the display corresponds precisely to the computer monitor, making it easy to adjust the layout.
- Programs can be changed at any time, including content, playback order, and duration, with immediate updates.
- The control computer can function as a network workstation, fetching real-time data from a server and displaying it on the screen.
This flexible and powerful system makes LED displays ideal for both commercial and public use, offering a dynamic and interactive way to convey information.
Constant Temperature And Humidity Test Chamber
An environmental test chamber artificially replicates conditions which machinery, materials, devices or components might be exposed to. It is also used to accelerate the effects of exposure to the environment, sometimes at conditions not actually expected.
Chamber testing involves testing and exposing products to various environmental conditions in a controlled setting. Climatic Chamber testing and Thermal Shock testing are part of chamber testing. Climatic Chamber testing is a broad category of ways to simulate climate or excessive ambient conditions exposure for a product or a material under laboratory-controlled yet accelerated conditions. On the other hand, Thermal Shock testing is used to simulate how materials will react when exposed to changes in extreme climatic conditions, such as going from extremely cold to extremely hot conditions in a very short period of time (usually only few seconds).
