Abstract:
1. A display device for emitting light comprising: a plurality of scan lines for transmitting scan signals; a plurality of data lines for transmitting data signals; and a plurality of pixel circuits each coupled to a respective scan line and a respective data line, wherein each of the plurality of pixel circuits comprises: a pixel driver for outputting a driving current corresponding to a respective data signal to an output terminal in response to a respective scan signal; first, second, and third light emitting elements for emitting first, second, and third color lights respectively, in response to the driving current; and first, second, and third switches respectively being coupled between the output terminal of the pixel driver and the first, second, and third light emitting elements, wherein the first, second, and third switches selectively transmit the driving current to the first, second, and third light emitting elements respectively, wherein two light emitting elements among the first, second, and third light emitting elements are arranged in a respective horizontal first line, and the remaining one light emitting element is arranged in a respective horizontal second line different from the respective first line such that the first, second, and third light emitting elements are arranged in a triangular shape, wherein a first pixel circuit and a second pixel circuit from the plurality of pixel circuits are arranged such that the first, second, and third light emitting elements of the pixel circuits are divided on both sides of a first scan line and in inverted relation between a horizontal first odd numbered line and a horizontal second even numbered line adjacent and parallel to the first odd numbered line, and both of the first pixel circuit and the second pixel circuit are responsive to said first scan line arranged in parallel with the first odd numbered line and the second even numbered line, wherein a third pixel circuit and a fourth pixel circuit from the plurality of pixel circuits are arranged such that the first, second, and third light emitting elements of the pixel circuits are divided on both sides of a second scan line subsequent and parallel to said first scan line and in inverted relation between a horizontal third odd numbered line adjacent and parallel to the second even numbered line and a horizontal fourth even numbered line adjacent and parallel to the third odd numbered line, and both of the third pixel circuit and the fourth pixel circuit are responsive to said second scan line arranged in parallel with the third odd numbered line and the fourth even numbered line, wherein the first, second and third light emitting elements of the first pixel circuit and the first, second and third light emitting elements of the third pixel circuit correspond to a same first data line, wherein the first, second and third light emitting elements of the second pixel circuit and the first, second and third light emitting elements of the fourth pixel circuit correspond to a same second data line, and wherein said first scan line is configured to select any of the three light emitting elements of the first and second pixel circuits and said second scan line is configured to select any of the three light emitting elements of the third and fourth pixel circuits, and the first, second, and third switches respectively control the output from the first and second data lines to the first, second, and third light emitting elements of the respective pixel circuits, and wherein the pixel driver comprises:
