Abstract
A display panel (1) has a first substrate (2) and a second substrate (3). The substrates (2, 3) are provided with electrodes (8, 9) and are separated from each other by a plurality of spacers (4). Holes (5) extend through the spacers (4) and the substrates (2, 3) and thus form through holes (5) extending through the display panel (1) making it permeable to gases and/or liquids. The substrates (2, 3) and the spacer (4) form the wall (6) of the respective through hole (5) and thus a space (7) can be sealed between the two substrates (2, 3) without any risk of leakage.
Claims15
A display panel comprising a first substrate (2;
- 102) and a second substrate (3;
- 103) being separated from each other by spacers (4;
- 104) and sealing between them a space (7), at least one of the spacers (4;
- 104) being penetrated by a hole extending therethrough and through both of the substrates (2, 3;
- 102, 103) to form a through hole (5;
- 105;
- 205;
- 215) through the display panel (1;
- 100;
- 200), said at least one of the spacers (4;
- 104) and the substrates (2, 3;
- 102, 103) forming the wall (6;
- 106) of said through hole (5;
- 105) and sealing the space (7) from the through hole (5;
- 105).
A method of manufacturing a display panel, comprising the steps of
- providing spacers (4;
- 104) on one side (17;
- 117) of a first substrate (2;
- 102),
- providing a second substrate (3;
- 103) on said one side (17;
- 117) of the first substrate (2;
- 102) such that the spacers (4;
- 104) hold the first and the second substrates (2, 3;
- 102, 103) separated from each other,
- forming a hole (S;
- 105) through at least one of the spacers (4;
- 104) and both of the substrates (2, 3;
- 102, 103) such that said at least one of the spacers (4;
- 104) and the substrates (2, 3;
- 102, 103) form the wall (6;
- 106) of the through hole (5;
- 105), and
- sealing a space (7;
- 107) between the substrates (2, 3;
- 102, 103) and the spacers (4;
- 104).
