ABSTRACT:
A projection display apparatus includes an image forming section that forms an image based on image information received from an external device, and a projection lens that projects the image formed by the image forming section. The projection display apparatus includes a substrate, a plurality of light emitting elements, a first driver and a second driver. The light emitting elements are two-dimensionally arranged on the substrate. The light emitting elements include rows of light emitting elements and columns of light emitting elements such that the rows are substantially perpendicular to the columns. The first driver element selectively drives the rows. The second driver element selectively drives the columns. The plurality of light emitting elements include three groups of light emitting elements aligned either in the rows or in the columns, each group emitting light of a different wavelength from the remaining groups.
