The utility model provides a display with high light
transmittance, which belongs to the technical field of
surface water micro-plastic detection, and comprises a sleeve shell and a protection
assembly arranged in the sleeve shell, the protection
assembly comprises a constraint frame, a protection film, a protection shell, an
extrusion cylinder, a mounting rack, a storage roller, a guide roller and a moving groove, the constraint frame is slidably sleeved at an opening of the outer wall of the sleeve shell, and the protection film is arranged in the protection shell. The protection shell is embedded in the inner wall of the sleeve shell, the inner wall of the protection shell is sleeved with the displayer body, and the
extrusion air cylinders are fixedly arranged at the corners of the inner wall of the sleeve shell. Through the protection
assembly, the protection film serving as a consumable can be continuously released and recycled, it is guaranteed that a picture generated by the displayer body with the high-light-transmitting function is continuously reflected by the protection film, the phenomenon that under strong
sunlight irradiation, the high-light-transmitting displayer possibly has reflection and
refraction phenomena is avoided, and the display effect is improved. Meanwhile, the display main body is protected, and the problem that the display main body is damaged due to collision or toppling is avoided.
