Resistive touch screen

Resistive touch screenDisplay systems are widely used in communication, power, and command structures, playing an important role in providing shared information, decision support, and situational display. The following introduces the main principles and precautions in the design and equipment selection of large screen display systems for readers' reference.

The large screen splicing display system is a multimedia interactive system that integrates multiple information reception, processing, and display, as well as multiple personnel operation and control. It involves various technical issues related to sound, light, and electricity, as well as management and coordination issues of relevant departments. It is also closely related to the overall structure of the display hall. It must pay attention to demand first, overall planning, and the use of comprehensive integration technology in order to achieve the expected effect.

Main functions and requirements of large screen splicing display system

The design of a large screen splicing display system first needs to propose requirements, and the following are the general main functions and requirements.

1. Information reception

Resistive touch screenNot only should it be able to receive VGA, RGB, and network computer information, but it should also be able to receive broadband voice and video signals and perform appropriate information conversion as needed.

2. Information display

The large screen splicing display system can publish shared information in the form of multimedia, and can display situation, text, tables, and video image information in different modes and according to divided areas. Require clear and high-resolution situation display, with clear and stable text and image display.

3. Preview, camera and switching

To ensure the accuracy and quality of the projection display information on the large screen splicing, the system must have a preview function for image preview. A camera should be installed in the display hall to extract video images of the management and control mechanism's work. The system should have a switching display function to meet the needs of displaying multiple information channels.

4. Video conference

The system can use monitoring, preview, switching, communication, and terminal control devices to maintain video communication with relevant parties and hold video conferences at any time.

5. Control mode

The system allows personnel, business staff, and security personnel to perform operations such as turning on and off the large screen, opening windows, selecting sources, projecting displays, adjusting audio and lighting through centralized control, mobile control, and authorization control.

6. Optimize design according to standards

The equipment configuration of the large screen splicing display system is complex, with numerous cable signals and high requirements for installation technology and environmental conditions. It is necessary to follow the standardization of machine lines, electromagnetic compatibility standards, and installation requirements of the large screen TV wall for engineering wiring and equipment installation to ensure that the system can operate stably for a long time.
