Abstract: An optimal viewing angle adjustment method for a multi-dimensional spatial three-dimensional display screen, including steps of setting optimal angle parameter data between the multi-dimensional spatial three-dimensional display screen and a viewer at a front end of the multi-dimensional spatial three-dimensional display screen, disposing a detection device on the multi-dimensional spatial three-dimensional display screen for viewer identification and distance identification, identifying a distance between the viewer and the multi-dimensional spatial three-dimensional display screen by the detection device in real time, and transmitting a position and a direction of the viewer to the multi-dimensional spatial three-dimensional display screen, and controlling the multi-dimensional spatial three-dimensional display screen to zoom in or out according to the position and the direction of the viewer.

Abstract: A zearalenone functionalized graphene surface molecularly imprinted material, a preparation method therefor and the use thereof, which belong to the technical field of molecularly imprinted materials. The zearalenone functionalized graphene surface molecularly imprinted material is prepared by using RGO as a carrier, CDHB as a template molecule, 1-ALPP as a functional monomer, TRIM as a cross-linking agent, AIBN as an initiator, and acetonitrile as a pore-forming agent.

Abstract: The present invention discloses an LED display module, an LED TV and an LED TV system, wherein a camera component is embedded on the LED display module; in this way, the LED TV is capable of taking pictures from middle of the display screen; because the participants are looking at the display screen, as a result, the local participants at local and the other end can look in the eyes, which improves sensory feeling of video interaction and realizes getting more information from the eye expression; because the camera component can take pictures from the front side, accuracy of taken feature information is improved; and the accurate feature information can facilitate accurate subsequent action analysis; as a result, the present invention realizes wider application of LED TV.
