Abstract

A matrix display for the display of alphanumeric characters one of the elements of the basically 5×3 matrix divided into two parts (P5a, P5b). The matrix can also be applied to a printer.

Claims

1. A matrix display for the display of alphanumeric characters, the elements (Pi) of the matrix forming a 5×

3 matrix with outer columns on either side of a center column, characterized in that one element in the middle column of the matrix and within the confines of a perimeter defined by the elements in the outer columns is divided into two parts (P5a, (P5b) so that the matrix comprises a total of 16 pixels (Pi).

2. A matrix display according to claim 1, characterized in that the divided element (P5) is in the second line of the middle column.

3. A matrix display according to claim 1, characterized in that the pixels of the matrix are shaped so that the pixel figure is asymmetrical in relation to the center lines (L1, L2) of the matrix.

4. A matrix display according to any of the above claims 1-3 or 9, characterized in that the pixels are formed on a liquid crystal panel.

5. A matrix according to any of the above claims 1-3 or 9, characterized in that the pixels are formed on a plasma display.

6. A matrix display according to any of the above claims 1-3, or 9 characterized in that the pixels are formed on an electroluminescence display.

7. A matrix display according to any of the above claims 1-3, or 9, in that the pixels are formed by means of a set of lamps.

8. A matrix display according to any of the above claims 1-3, or 9 characterized in that the pixels are formed by means of mechanical display plates.

9. A matrix display according to claim 2, characterized in that the pixels of the matrix are shaped so that the pixel figure is asymmetrical in relation to the center line (L1, L2) of the matrix.

10. The matrix display according to claim 3 wherein said divided pixel is generally V-shaped with each element being a leg of the V-shape.
