Problems solved by technology

The drawback of this solution is that it does not ensure a sufficiently uniform distribution of the absorber over the entire surface of the display panel
This solution is particularly unfavorable for cases such as large display panels with a diagonal of more than 20cm

no. 1 example

[0051] refer to image 3 , through the method described above, each cavity 107 is positioned between two adjacent electroluminescent units in the same cell row and / or the same cell column. image 3 More specifically, the case where there is a cavity between two cells in two adjacent rows and between two cells in two adjacent columns is shown.

no. 2 example

[0053] refer to Figure 6 , each cavity 107 is positioned between two laterally adjacent (transversely adjacent) electroluminescent cells 102, in other words, located between two adjacent electroluminescent cells that neither belong to the same row nor to the same column. between unit 102.

no. 3 example

[0055] refer to Figure 7 , the cavity 107 is positioned on the inner surface of the front panel of the entire active surface of the display panel according to the first and second embodiments. Here, there is an array of cavities 107 positioned such that each electroluminescent cell 102 except the last cell of a row or column is surrounded by eight cavities.

Abstract

An image display panel of the "top emission" OLED type, comprising: an array of cavities or grooves 107 located on the inner surface of the front plate 106 facing the viewer, and the cavities or grooves are distributed in the light emitting unit Between, and contains absorber 108, said absorber 108 is especially used for absorbing the trace amount of oxygen and / or water vapor that tends to deteriorate the organic electroluminescence unit 102. Thereby, the service life of the display panel can be improved.

Description

technical field [0001] The invention relates to an image display and / or lighting panel comprising two panels, a front panel facing the viewer and a rear panel, said panels being sealed and leaving a seal between them. space; the array of cells is capable of emitting light through the front plate and is distributed between these two plates; and in this sealed space there is an active absorber. Background technique [0002] Document EP1143539 discloses a display panel of this type, the cells of which comprise an organic electroluminescent layer in equilibrium with the atmosphere of the enclosed space. Since the electroluminescent layer is organic, it is particularly sensitive to any traces of oxygen and / or water vapor in the space. Oxygen and / or water vapor interfere with and deteriorate the constituent materials of the organic electroluminescent layer, especially its luminescence ability, thereby reducing the display quality and / or the service life of the panel. [0003] In...
