Abstract

A display apparatus includes a display panel and a light source module. The display panel displays a first image during an N-th frame included in a first interval and an (N+1)-th frame included a second interval, where N is a natural number. The light source module includes a first light-emitting module, a second light-emitting module and a light source driving part. The first light-emitting module includes first to k-th top light source blocks disposed adjacent to a first edge of a light guide plate, where k is a natural number. The second light-emitting module includes first to m-th bottom light source blocks disposed adjacent to a second edge of the light guide plate, where m is a natural number, and the second edge is disposed opposite to the first edge. The light source driving part generates first to k-th top duty control signals and first to m-th bottom duty control signals based on the first image, selectively generates first to k-th top driving signals and first to m-th bottom driving signals using the first to k-th duty control signals and the first to m-th duty control signals, respectively, based on a three-dimensional image enable signal, and drives the first light-emitting module during the first interval and the second light-emitting module during the second interval, where the first to k-th top duty control signals correspond to the first to k-th top light source blocks, and the first to m-th bottom duty control signals correspond to the first to m-th bottom light source blocks, and where the first to k-th top driving signals drive the first light-emitting module, and the first to m-th bottom driving signals drive the second light-emitting module.
