摘要： A manufacturing method of a display apparatus includes providing a backlight unit under a display panel to provide a light to the display panel. The providing of the backlight unit includes disposing a light source on a substrate to emit the light, disposing a mask above the light source, which includes a first opening and a second opening greater than the first opening disposed under the first opening, and providing a transparent resin including a wavelength converting material on the light source through the first and second openings to form a wavelength converting member. A width in a cross section of the wavelength converting member along a direction substantially vertical to the substrate becomes smaller as a distance from the substrate becomes greater.

摘要： A light source device includes a light source module having a light-emitting block, an image analysis part, a duty ratio calculation part, a duty ratio determination part and a signal generation part. The image analysis part extracts representative luminance data of the light-emitting block based on pixel data. The duty ratio calculation part calculates duty ratio data of the light-emitting block based on the representative luminance data. The duty ratio determination part generates determined duty ratio data of the light-emitting block based on the duty ratio data from a first period, and the signal generation part generates a driving signal having a duty ratio corresponding to the determined duty ratio data to drive the light-emitting block.
