Abstract
A display device with a cooling circuit in the screen to limit the rise in temperature of the luminescent material, particularly during strong current densities of the electron beam. The device comprises a window formed of an optical fiber plate of which one or several cladding glasses have been partially removed in order to form channels for the passage of a cooling liquid while maintaining studs comprising light conductors formed by the glass core surrounded by a cladding glass of the optical fiber plate. A transparent display window having a luminescent layer is glued or sealed to the window thus constituting a cooling network connected to an external circulation by pipes embedded in moulding tubes.
