Abstract: A tiled display device includes a plurality of display panel modules arranged adjacent to each other. Each of the plurality of display panel modules includes a display panel including a display area and a bezel area at least partially surrounding the display area, a light blocking layer disposed on the display panel and extending from the display area to a portion of the bezel area, and a protective layer disposed on the light blocking layer. In the bezel area, a distance from an end of the display panel to an end of the protective layer is greater than a distance from the end of the display panel to an end of the light blocking layer. Accordingly, an air layer is not formed between the protective layer and the display panel. A visibility of a seam area is reduced.

Abstract: A display device including: a display panel having red, green and blue pixels; a backlight unit; a data driver; and a controller for applying red, green, and blue image data signals, wherein, when the red image data signal of a current frame has a magnitude different from a magnitude of the red image data signal of a previous frame, the controller applies a corrected image data signal having a magnitude different from the magnitude of the red image data signal of the current frame to the data driver as a red image of the current frame, and when the green image data signal of the current frame has a magnitude different from a magnitude of the green image data signal of the previous frame, the controller applies the green image data signal of the current frame to the data driver as a green image of the current frame.

Abstract: A display device includes: a display panel which displays an image with light and a drive unit which is electrically connected to the display panel and drives the display panel. The drive unit includes a drive circuit board and a drive circuit film. The drive circuit board overlaps the display panel, generates a drive signal to drive the display panel and defines a receiving hole therein. The drive circuit film electrically connects the display panel to the drive circuit board and is bent from the display panel toward the drive circuit board. The drive circuit film includes a driver chip which provides a control signal in response to the drive signal from the drive circuit board. The driver chip is received in the receiving hole defined in the drive circuit board.

Abstract: A display device includes a display panel, a backlight unit to provide a light to the display panel, a reflective member, and a light blocking member. The backlight unit includes a light guide member and a light source to provide the light to one side portion of the light guide member. The reflective member is disposed on the other side portion of the light guide member. The light blocking member covers the reflective member and at least a portion of corners of the light guide member.

Abstract: A display device includes: a display panel curved in a first direction; a light source which emits a light; and a light guide plate which guides the light from the light source toward the display panel. The light guide plate includes an exit surface curved in the first direction corresponding to a shape of the display panel and an incidence surface, which is defined by a side surface of the light guide plate in the first direction, where the light from the light source is incident onto the incidence surface. The incidence surface is substantially parallel to a normal line at a central portion of the exit surface.
