According to the new requirements for dense installation of displays and prevention of light leakage between displays put forward by the operators during the mockup verification of the main control room of project C,the anti-seismic OWP named screen style is developed.The anti-seismic OWP named screen style of nuclear power plants can meet the new requirements through the coordination of the screens and the display supports.The screen with a high natural frequency and the slide structure through the width direction can realize the left and right movement and installation of the display support,that can realize the left and right movement of the display.The display support itself can realize the front and rear movement and the angle adjustment in all directions of the display.Together they enable intensive installation of displays.The screens act as a physical barrier to avoid light leakage in the gaps between the displays.Verification has shown that the anti-seismic OWP named screen style can avoid light leakage in the gaps between the displays and enables the displays to be evenly arranged with a minimum pitch of 10 mm and can meet the seismic requirements of related nuclear power plants.
