Abstract

The invention provides a self-healing transparent display film. The preparation raw materials of the film comprise a self-healing material and imaging particles. The imaging particles enable the filmprovided by the invention to have the image display capability so that the film can be used as a display screen. The self-healing material enables the film provided by the invention to have the self-healing capability, when broken partially, the film does not need to be replaced integrally, and the broken part can heal itself, therefore, the replacement of the display screen can be avoided, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of display equipment, and relates to a self-healing transparent display film and a preparation method and application thereof. Background technique [0002] The transparent display screen can display images clearly without affecting the observation of things behind the screen. Transparent display technology is a rapidly developing technology and has been applied in many fields. Through transparent display screen technology, navigation information, instrument panel information, etc. can be displayed on the front glass of cars and fighter jets. While the driver obtains relevant information, it will not affect his observation of the front and improve driving safety. Combined with transparent display technology, ordinary glass walls and even glasses can also be turned into display screens for work or entertainment. Currently common transparent display screens can be classified into head-up display screens, diffuse refle...
