IMAGE DISPLAY PANEL

摘要

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.
