▎ 摘　　要

NOVELTY - The structure has an electrical machine (1) connected with a speed reducer (3). A lifting device has a display base (6) fixedly set on a lifting guide rail (7). The rail is provided with an inner screw that connects a bearing (5) with the reducer. A lifting adjusting sleeve extends to the lifting guide rail that is connected with an adjusting rod (9). A position regulating rod is hinged with a computer display (2) through a connecting unit. A liquid crystal screen is set with a radiation-proof film exhibiting a graphene thin film layer and silicon glue film layer. USE - Light compensation structure for a computer display. ADVANTAGE - The structure is simple and exhibits enhanced light effect. DESCRIPTION OF DRAWING(S) - The drawing shows a side partial sectional view of a light compensation structure.
