摘要： A light guide plate includes a body region and a light incident region. The body region has a light exiting surface, an opposite base surface, and a side surface between the light exiting surface and the base surface. The light incident region is located at the side surface of the body region for receiving incident light and includes projections protruding outwards from the side surface of the body region, and a cavity is defined between adjacent projections. Each projection has a top surface and outer side walls. The outer side walls also define inner side walls of each cavity together with a bottom surface. The top surface, side walls, and bottom surface together are a light incident surface of the light incident region. An angle between the top surface and each outer side wall is called an apex angle, which is greater than 90 degrees.

摘要： A backlight module and a display apparatus are provided. The backlight module includes a film sheet, including a first opening and a second opening; and a light guide plate, including a first limit boss located within the first opening and a second limit boss located within the second opening. The second limit boss limits a position of the film sheet in a first direction; the first limit boss limits the position of the film sheet in a second direction. In the second direction, a first interval between is between a portion of the film sheet that forms the second opening and the second limit boss; and the portion of the film sheet that forms the second opening includes two first sidewalls opposite to each other in the first direction.

摘要： A diffusion sheet, a backlight module, a liquid crystal display panel and a display device are disclosed. The diffusion sheet comprises a base layer, a white printed layer and a black printed layer. The base layer comprises a peripheral region and a light transmitting region. The white printed layer and the black printed layer are arranged in the peripheral region. In a direction from a light incident surface to a light exit surface of the base layer, the black printed layer and the white printed layer are arranged in this order. An orthographic projection of the black printed layer on the base layer falls within an orthographic projection of the white printed layer on the base layer. In this way, the white printed layer can block a shadow which is formed by reflection of the black printed layer from the prismatic sheet, and thus improve the display quality.
