Description

Technical Field

[0001] This utility model relates to the field of backlight panel technology, specifically to a backlight panel with a snap-on design. Background Technology

[0002] Electronic backlights play a vital role in people's lives. Traditional backlighting uses a simple planar light guide plate combined with a corresponding reflective and diffuser film to achieve the backlighting effect. This type of backlighting is extremely bright at the source, decreasing in brightness with distance, resulting in poor backlighting performance. Over time, significant differences in brightness can occur, rendering only certain areas of the backlight usable and greatly impacting its overall performance. Furthermore, backlights are typically fixed to objects with screws, making installation and removal inconvenient, time-consuming, and labor-intensive. Additionally, while thick glass plates cover the diffuser film for protection, these are often simply glued to the film. Over time, the glass plate is prone to falling off, losing its protective function, and sometimes even detaching from the diffuser film, rendering the backlight unusable.

[0003] Therefore, existing backlight panels need further improvement to address the above issues. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of uneven display, dim display, inconvenient installation and disassembly, and easy drop of the protective glass plate in existing backlight panels. Through a rational design of the backlight panel, using a backlight panel frame, reflector, light guide plate, bottom diffuser plate, light diffuser plate, top diffuser plate, LED light board, lower clip, upper clip, and metal pins, it can achieve uniform display, improve display brightness, facilitate installation and disassembly, and prevent the glass plate from falling off. The use of a light diffuser plate with mutually perpendicularly arranged gratings can achieve uniform light distribution on the light guide plate and bottom diffuser plate. The light emitted from the diffuser is refracted and reflected to achieve balanced illumination of the backlight panel. Adjustments and compensation are made on the prism surface to further improve light uniformity. The use of a reflector prevents light leakage and greatly enhances light utilization. The use of equally spaced parallel LED panels achieves balanced light source illumination, and even if a single LED is damaged, balanced illumination can still be achieved. The use of a light guide plate with raised triangular prisms better refracts and reflects LED light towards the backlight panel, improving the light emission uniformity of the backlight panel.
