Abstract: A light source device includes a substrate and a plurality of light-emitting units disposed on a surface of the substrate. At least one of the light-emitting units includes a light source chip and an optical material layer covering the light source chip. A maximum width is defined as a distance between two farthest points on a pattern corresponding to a vertical projection of the optical material layer on the surface of the substrate, and a half of the maximum width is defined as a first width R. A maximum height H is defined as a vertical distance from the surface of the substrate to a highest point of the optical material layer away from the substrate. A ratio of R to H is between 5 and 1000. A display device applying the light source device is also provided.

Abstract: A tiled display device includes two panels and two cover layers respectively disposed on the two panels. The two cover layers include a contact region. A top portion and a bottom portion of the contact region have a height H. One of the two cover layers has a thickness Tn. One of the two panels has a distance Xn between an upper surface of the one of the two panels and the bottom portion of the contact region. The one of the two panels is corresponding to the one of the two cover layers. The height H, the thickness Tn and the distance Xn satisfy the equation: 0

Abstract: A backlight assembly includes an optical plate, a light source provided near the optical plate, and a brightness redistribution film provided above the optical plate. When light emitted from the light source passes through the optical plate and the brightness redistribution film, a front view angle brightness measured in a normal direction of a light exiting surface of the brightness redistribution film relative to a maximum brightness emitted from the backlight assembly has a brightness ratio N, wherein the brightness ratio N is greater than or equal to 60% and is smaller than 100% (60%≤N
