Description

a glass projection

technical field

The utility model relates to the projection field, in particular to a glass projection sheet.

Background technique

Traditional transparencies are generally made of PET film. By making patterns or logos on PET film, not only the method of making patterns is very simple, but also generally easy to scratch, and has the characteristics of easy deformation of patterns and preservation of patterns. Due to the short time, the quality of the projected pattern cannot be guaranteed. The prepared pattern is then irradiated with a strong light source and imaged through an optical lens assembly. Due to the high power of the light source and high light intensity of the strong light source, the chemical stability of PET is generally low. After being irradiated by high temperature or strong light, the internal chemical substances will change, which will easily cause the aging or deformation of the PET film. Blurring, light leakage and other undesirable phenomena appear in the projected image, which reduces the service life of the PET film and affects the projection quality of the projected image.
