Guang 2 Kanban 'As the head of (4) L made in the above-mentioned manner = or advertising billboards, using fluorescent tubes as a light source or indirect projection, Sa r enhances the brightness of advertising signs. The use of fluorescent tubes has the following disadvantages: (" —) The light source of the signboard is unevenly distributed. The area near the lamp is often brighter, causing the area farther away from the lamp to be darker. (2) The fluorescent tube is more power-consuming and has a shorter life span and a higher probability of damage; c) The thickness of the fluorescent tube affects the size of the signboard, which is more space-consuming. (4) The traditional use of the neon tube as an advertising sign, the overall visual effect can not be exciting. Indirect projection usually uses high-power halogen lamps as the light source, halogen In addition to power consumption, the high temperature around the lamp is also a deficiency. The inventor proposed a novel advertising billboard structure, as described in the national new patent No. 254682. The upper casing, the lower casing and a backlight module are used to form an ultra-thin advertising billboard, and the light guide plate, the light-transmitting sheet and the reflection sheet in the backlight module are used to reflect the light emitted by the cold cathode official, so that the whole of the advertisement billboard 5 1330345 The thickness is greatly reduced. This method mainly uses the known application to replace the function of the fluorescent tube in the backlight module of the thin display screen, and then transferred to the advertising board. However, the application of the technology cannot be extended to have a curved surface. In the structure of the kanban, in more detail, if the structure is applied to the curved surface billboard, the light emitted by the cold cathode tube will not be evenly distributed in the backlight module, and like the fluorescent tube, the area close to the tube tends to be more Bright, causing a darker area away from the lamp tube. • The inventors have proposed the structure of the curved advertising billboard of the present invention in order to overcome the above technical problems. [Invention] It is an object of the present invention to provide a curved surface design. The advertising billboard, the curved advertising billboard adopts a thin backlight module as the overall light source of the kanban.
