Abstract

The invention provides a high-contrast transparent projection display screen and a manufacturing method thereof. The projection display screen comprises an imaging layer, a light absorbing layer and an anti-reflection layer, wherein the light absorbing layer is located between the imaging layer and the anti-reflection layer. The projection display screen has high contrast, is flexible and foldable, and can be restored completely after bending and folding, and the display effects are not influenced. The projection display screen provided in the invention can be used for both front projection and back projection, and the obtained projection display screens can be seamlessly joined to form a display screen with an extra large size.

Description

technical field [0001] The invention belongs to the field of projection equipment, and relates to a projection display screen and a preparation method thereof, in particular to a high-contrast transparent projection display screen and a preparation method thereof. Background technique [0002] The transparent display screen can display images clearly without affecting the observation of things behind the screen. Transparent display screen 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, which can 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 co...
