Display device having a power line arrangement for reducing voltage drop

摘要

A display device includes: a pixel area comprising pixels in rows and columns; main power lines at a first side of the pixel area and a second side of the pixel area facing the first side; first sub-power lines coupled to a first main power line of the main power lines formed at the first side and extending into the pixel area in a column direction; and second sub-power lines coupled to a second main power line of the main power lines formed at the second side and extending into the pixel area in the column direction, wherein the first sub-power lines and the second sub-power lines extend in different columns of pixels, and wherein a column of pixels of the pixels are alternatingly coupled to a neighboring sub-power line of the first sub-power lines and a neighboring sub-power line of the second sub-power lines.

主权项

1. A display device comprising:
a pixel area comprising a plurality of pixels arranged in a plurality of rows and a plurality of columns; a plurality of main power lines formed at a first side of the pixel area and a second side of the pixel area facing the first side; a plurality of first sub-power lines coupled to a first main power line of the main power lines formed at the first side of the pixel area and extending into the pixel area in a column direction; and a plurality of second sub-power lines coupled to a second main power line of the main power lines formed at the second side of the pixel area and extending into the pixel area in the column direction, the second main power line being configured to supply a same voltage as the first main power line, wherein the plurality of first sub-power lines are not directly coupled to the second main power line, wherein the first sub-power lines and the second sub-power lines extend between different columns of pixels, and wherein a column of pixels of the pixels are alternatingly coupled to a neighboring sub-power line of the first sub-power lines and a neighboring sub-power line of the second sub-power lines.
