▎ 摘　　要

NOVELTY - The screen has a track control electromagnetic module arranged between a hidden slide rail and a hidden groove sheet (2). The track control electromagnet module is provided with multiple electromagnetic sheets that are electrically connected to a surface of the hidden slide track. A position control sliding block is fixedly connected on a back of a LED screen main body (1). A hidden groove sheet is fixedly connected to an opening of a recessive sliding groove (3). Multiple follow-up self-concave sheets are respectively connected to an inner end surface of a hidden chute sheet. Self-cave pieces are fixedly connected with electromagnetic sheets. The electromagnetic sheets and a global positioning system (GPS) positioning module are connected with a controller. USE - Lifting type large eye-protecting meeting LED screen for carrying a carbon footprint programming module in a large conference hall of a display screen in an electronic information product. ADVANTAGE - The screen adjusts and lifts large conference LED screen according to requirement of meeting participant, realizes certain eye-protecting effect for a staff during long time parameter. The screen has smooth lifting control, generates position control sliding block between the moving and the recessive slide rail of the force can be transmitted to the strip powder. The screen is convenient for an inner graphene of powder, and improves integrity and beauty of mounting wall LED. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a lifting type large eye-protecting meeting LED screen for carrying a carbon footprint programming module in a large conference hall of a display screen in an electronic information product. 1Screen LED 2Hidden groove sheet 3Recessive sliding groove
