Flexible Screen Comprising Cathodic Microtubes

Abstract

Disclosed is a flexible display device, each image point of which comprises one or several cathodoluminescent capsules (11) that are individually sealed and are mounted on a flexible substrate (12, 13) by means of an automated process. The invention relates to the realm of flat screen displays including large-size screens typically having a diameter exceeding one meter. Such screens traditionally comprise a set of image elements or pixels which are organized in a matrix and are addressed by means of a network of conductors arranged in rows and a network of conductors arranged in columns. According to the invention, said display elements represent capsules (11) which constitute miniature cold cathode tubes comprising one capsule for each color point of each pixel, for example. Moreover, said capsules (11) are designed such that they can be assembled in an automatic manner and form a flexible screen without the need for the capsules (11) to be transferred onto a flexible substrate in a complex process.
