1. Screen specifications:
- Size: The 55-inch diagonal screen provides a large viewing area, which is suitable for scenarios where a big display is required to convey information effectively, such as in conference rooms, classrooms, and exhibition halls. The display area typically measures around 1209 (h) × 680 (v) in millimeters.
- Resolution: It usually has high-definition resolutions, such as 1920×1080 or even 4K (3840×2160), ensuring clear and sharp image quality. This allows for detailed display of text, images, and videos.
- Brightness and contrast: With a certain level of brightness (e.g., 500 cd/㎡) and high contrast ratio (e.g., 1400:1), the screen can present vivid colors and distinct dark and light areas, making the content more visually appealing and easy to read even in well-lit environments.
- Viewing angle: A wide viewing angle, around 178°, enables people to view the screen clearly from different directions, ensuring that the image quality does not deteriorate significantly when viewed from the side or at an angle.
2. Touch technology:
- Sensitivity: The touch function is highly sensitive, allowing users to perform various operations such as sliding, clicking, and dragging with ease and quick response. This enables smooth and efficient interaction between the user and the screen.
- Accuracy: It offers accurate touch positioning, ensuring that the input is precisely registered on the screen, which is essential for tasks that require precise control, such as drawing, annotating, and gaming.
- Durability: The touch screen is designed to be durable, capable of withstanding a large number of touch operations. For example, it can endure over 60 million times of single-point touch, ensuring long-term reliable use.
3. Appearance and design:
- Material and structure: The exterior is usually made of high-quality materials such as metal or alloy, which are sturdy and durable. The cabinet has a thickness of at least 1.5mm to ensure stability. The surface treatment is done to be rust-proof, corrosion-resistant, and wear-resistant, making it less prone to damage and easy to maintain.
- Installation methods: It supports various installation methods, including floor-standing, upright, wall-mounted, embedded, and mobile, providing flexibility in different application scenarios. For example, in a retail store, a floor-standing or wall-mounted 55 inch touch screen can be used for product promotion and information display; in a classroom, a wall-mounted or embedded one can be used for teaching.
4. Interface and connectivity:
- Signal input interfaces: It is equipped with common signal source interfaces such as HDMI, VGA, and audio function interfaces, allowing for easy connection to various external devices such as laptops, desktops, game consoles, and media players. This enables users to display content from different devices on the touch screen.

5. Applications:
- Commercial and advertising: In shopping malls, supermarkets, and chain stores, it can be used for product advertising, promotional activities, and customer interaction. For example, customers can use the touch screen to browse product information, watch product demonstrations, and even place orders directly.
- Education and training: In schools, training institutions, and corporate training rooms, it is an effective teaching tool. Teachers can use it to display teaching materials, conduct interactive teaching, and students can use it to answer questions and participate in discussions.
