Description of the new type: [Technical field to which the new type belongs] This creation is a direct-thin, thin-type light-emitting diode backlight module, especially referring to Weitong, which uses hairpin «(LED) as backlight · The backlight module can achieve the purpose of high brightness and thinness. [Previous technology] With the development of liquid crystal display (LCD) technology, the number of products that use liquid crystal display panels as display interfaces is increasing, such as digital cameras, digital personal assistants (pDA), TV • TV 11, mobile phones and flat screens. TV materials, and the backlight module is one of the key components of LCD products. According to the position of the filament of the backlight module, the backlight module can be divided into an edge type and a vertkal type. The light source of the side-type backlight module is unilaterally or bilaterally arranged, and guides the light scattering direction through a light guide plate to provide a planar light source. The light source of the direct type backlight module is placed directly below the display panel, and then the light source is projected upward to the upper diffuser. As shown in the figure, the conventional side-type backlight module includes a light-emitting diode 10, two light plates 14, 16 and a reflection plate 12. After the light-emitting diode emits a light source, it passes through two guides. After the light plates 14 and 16 and the anti-E12 are mixed and reflected, they will spread the system evenly. However, this side-type backlight has the disadvantage of low brightness despite its thickness. As shown in the second figure, 'is a conventional direct type backlight module, which includes a back plate 28, a reflective plate 20, a cold cathode tube (CCFL) 22, a casing%, and a diffusion plate 26. When the cold pole cathode tube 22 emits the light source to the top, the light source M273734 is evenly dispersed by the diffuser%, and the light source under the diffuser role is reflected by the reflector 2Q. Although the brightness is high, the overall When the thickness is thicker, it is not suitable for thin design. The author feels that the above-mentioned shortcomings can be improved. He has devoted himself to studying and cooperating with the application of theories, and then proposes a rationally designed and effective improvement of the above-mentioned shortcomings. [New content] The main purpose of this creation is to provide a direct-thin and thin light-emitting diode backlight module, especially refers to a kind of light-emitting diode (LED) as a light source of the backlight module. The moonlight module achieves the purpose of south brightness and thinning. "In order to achieve the above purpose, the direct-thin thin-type light-emitting diode backlight core of this creation includes:-a printed circuit board, a plurality of light-emitting diodes, and a light guide plate. Among them, a plurality of light-emitting diode systems are arranged in The printed circuit board provides a backlight module = a light source 'light emitting diode that emits the light source to the upper light guide plate, and the light source is evenly dispersed by the ^ plate to form a thin, straight-type light emitting diode backlight. [Embodiment] Reference = Three_show, for the straight down type thin light-emitting diode back = board set diagram 'includes printed circuit board%, multiple light-emitting diodes ^, board 36 # A plurality of light-emitting diodes 34 are arranged on the printed circuit board 30 to provide the light source required for the backlight module. The light-emitting diode 34 emits the light source ^ the light guide plate 36 located above, and guides 36 The light source is evenly dispersed to form a straight-type light-emitting diode backlight module of the Tao type. This thin-type thin-type light-emitting diode backlight module of the direct-type type further includes a reflective plate 32 'posting plate 32 series Placed on the Indian road board 3q, the reflection board will scatter 6 M273 734 The bottom line can increase the working rate of light and make the direct-thin thin-type light-emitting diode backlight module of this creation more uniform and brighter. The above-mentioned reflecting plate 32 can be Shao metal or its Alloy, foamed ρΕτ film or% resin. The direct-type thin light-emitting diode backlight module of this creation can be arranged on the light guide plate 36 to correspond to the relative robustness of the plurality of light-emitting diodes 34, and a plurality of light-emitting diodes 34 can be arranged. Each dot 38, 'can make the light source more uniform, and further-reduce the thickness of the backlight module, and achieve a straight-type light emitting diode backlight module with uniform light source, higher brightness and thinner thickness. 上 逑 之The plurality of light-emitting diodes 34 may be white light-emitting diodes, or may be composed of two types of light-emitting diodes of red, green, and monitor colors, and then mixed into white light to form a light source required for the backlight module. It is stated that this creation is a rare new creation product, which is extremely industrially usable, novel, and progressive, and fully meets the requirements of the new patent application. Send an application according to the law. Please check and approve this case.
