A method of displaying information on the wheel of a vehicle, the method comprising: mounting a display device on the wheel, wherein the display device comprises a printed circuit board having a portion on which first and second strips (110, 112) of light emitting elements are mounted such that the first and second strips (110, 112) of light emitting elements lie substantially along first and second radii of the wheel, and either side of a third radius of the wheel, wherein said first and second radii of said wheel are separated by an included angle, and when the display device is mounted on the wheel the portion of the printed circuit board on which the first and second strips are mounted extends along said third radius; and wherein said light emitting elements are arranged along each said strip and define radial lines of pixels; and wherein radial positions of the light emitting elements of said first strip are interleaved in a radial direction with respect to positions of the light emitting elements of said second strip; and driving said first and second strips (110, 112) of light emitting elements to display an image, wherein said image is represented by radial lines of pixels at successive angular positions; and wherein said driving comprises: driving said first strip of light emitting elements with a first subset of pixels of a first radial line of said image at a first said angular position in the image when said first strip of light emitting elements is at a reference angular position; driving said second strip of light emitting elements with a second subset of pixels of said first radial line of said image at said first angular position in the image when said second strip is at or adjacent said reference angular position, wherein said first and second subsets of pixels comprise interleaved pixels of said first radial line of said image; and wherein said driving further comprises driving said second strip of light emitting elements with a first subset of pixels of a second radial line of said image when said first strip of light emitting elements is at or adjacent said reference angular position, and wherein in said representation of said image said second radial line of said image is angularly displaced from said first radial line of said image by said included angle. mounting a display device on the wheel, wherein the display device comprises a printed circuit board having a portion on which first and second strips (110, 112) of light emitting elements are mounted such that the first and second strips (110, 112) of light emitting elements lie substantially along first and second radii of the wheel, and either side of a third radius of the wheel, wherein said first and second radii of said wheel are separated by an included angle, and when the display device is mounted on the wheel the portion of the printed circuit board on which the first and second strips are mounted extends along said third radius;
