Title
(EN) IMAGE DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE D'IMAGES
Abstract
(EN)
The present invention relates to an image display panel (1) comprising a first substrate (7) and a second substrate (19). The first substrate (7) comprises a number of channels (15) extending in a first direction, which channels (15) are provided with an ionizable gas mixture. First electrodes (9) extend parallel to the channels. Pairs of second electrodes (21) are present perpendicular to the channels (15). An image cell is created by selective ionization of the gas mixture between two electrodes (21) of such a pair, at the position of a crossing of a first electrode (9). An array (27) of cylindrical lenses (29) is arranged on the viewer's side of the image display panel (1). The longitudinal axis of the cylindrical lenses (29) extends substantially parallel to the second electrodes (21). The pitch of the lens array (27) may be equal to the vertical pitch of the image cells (31), while the array (27) is shifted with respect to the image cells (31) in a direction substantially perpendicular to the second electrodes (21). The pitch of the lens array (27) may also be smaller than the vertical pitch of the image cells (31), combined or not combined with a shift of the lenses (29) with respect to the image cells (31) in a direction substantially perpendicular to the second electrodes (21). The light intensity of the image within the viewing angle is increased, and intensity variations of the image across the panel are reduced.

Cette invention a trait à un panneau d'affichage d'images (1) comprenant deux substrats (7, 19). Le premier substrat (7) comporte un certain nombre de canaux (15) se déployant dans une première direction et contenant un mélange gazeux ionisé. Une première série d'électrodes (9) se déploie parallèlement à ces canaux (15) et, à la perpendiculaire de ces canaux (15), se trouvent des paires d'une seconde série d'électrodes (21). Une cellule d'image est créée par ionisation sélective du mélange gazeux entre les deux électrodes (21) de la paire susmentionnée, là où elles se croisent avec une électrode (9) de la première série. Le coté spectateur du panneau d'affichage d'images (1) est pourvu d'une mosaïque (27) de lentilles cylindriques (29) dont l'axe longitudinal s'étend quasiment parallèlement aux électrodes (21) de la seconde série. L'inclinaison de la mosaïque (27) de lentilles peut être égale à l'inclinaison verticale des cellules d'image (31) tandis que ladite mosaïque est décalée par rapport aux cellules d'image (31), dans une direction quasiment à la perpendiculaire des électrodes (21) de la seconde série. Cette inclinaison de la mosaïque (27) de lentilles peut également être inférieure à l'inclinaison verticale des cellules d'image (31), en association ou non avec un décalage des lentilles (29) par rapport aux cellules d'image (31), dans une direction quasiment à la perpendiculaire des électrodes (21) de la seconde série. L'intensité lumineuse de l'image à l'intérieur de l'angle de vue est accrue et les écarts d'intensité de l'image sur tout le panneau sont réduits.
