Description of the new type: [Technical field to which the new type belongs] This creation is about a kind of backlight module, especially a kind of backlight module using Cold Cathode Fluorescent Lamp (CCFL) light source. [Prior technology] Because the liquid crystal display device is light, thin, and consumes little electricity, it is widely used in modern information equipment such as notebook computers, mobile phones, and personal digital assistants. However, the liquid crystal itself does not have a light-emitting property, so a backlight module needs to be provided for the liquid crystal display device to realize a display function. The backlight module of the prior art includes a light source and a light guide plate. The light source is disposed opposite to the light incident surface of the light guide plate. The light guide plate guides the transmission direction of the light beam emitted from the light source, and converts a linear light source or a point light source into a surface light source for emission. The main linear light source used in the backlight module is the cold cathode fluorescent lamp light source. The cold cathode fluorescent lamp light source has the advantages of low working voltage, high luminous brightness, and long life. Please refer to the first figure, which is a schematic diagram of a backlight module disclosed in the prior art. The backlight module includes a light source 10 and a light guide plate 20. The light source 10 mainly includes a substrate 11 and a plurality of cold cathode fluorescent lamps 12. Please refer to the second figure, which is a schematic plan view of the light source of the backlight module disclosed in the first figure. The light source 10 includes a substrate 11 and a plurality of cold-cathode fluorescent lamps. The plurality of cold-cathode fluorescent lamps 12 are arranged in a row, and the plurality of cold-cathode fluorescent lamps 12 have a certain gap therebetween. Since the cold cathode fluorescent lamp 12 is a long linear transparent light source, for the area surrounded by the cold cathode fluorescent lamp 12a and the cold cathode fluorescent lamp 12b, the main light source M272108 is the cold cathode fluorescent lamps 12a and 12b. Therefore, the distance from the light source 12a and the light source m are farther away from the light source than the other parts of the area, and therefore, the light in the middle part is darker, so the brightness of the backlight module is uneven. Please refer to the third figure'4, 1995, published on July 7, US Patent No. 5,387,921, which discloses a kind of hibiscus ___ Yue Yuejiu. The light source of the backlight module includes a base plate 2 and a cold cathode fluorescent lamp M. The wide cathode 23 of the cold Yinzaki light lamp η is connected to a driving power source through a wire 24. 1 Please refer to the fourth figure, which is the schematic diagram of the third figure along rv- 戦. The multiple cold-cathode fluorescent lamps are arranged in close contact with 22 wires, and the shooting interval is extremely small. Therefore, Gu Beiguang's module has a high level of uniformity and wrinkles, that is, increasing the cold-yin-to-different method. The method to improve the overall backlight module Brightness and evenness. However, this method will inevitably increase the driving load and increase the power consumption. …,… In view of this, it is necessary to provide an optical module and a liquid crystal display device that can increase the brightness and uniformity without increasing the load. [New content] Zaizhi = Γ Jingsu-Shooting and increasing Jingshan shirt does not increase the burden Another purpose of this creation is to provide a liquid crystal display device that can increase brightness and uniformity and load. Corresponding to the above purpose, this creation provides-seeding module, including. Including Γ smooth surface; and-Yang, which is set relative to the light-guiding person's smooth surface, 4 including a plurality of cold cathode fluorescent lamps; The cathode fluorescent lamp has a rectangular wave-shaped M272108 structure. Corresponding to the above purpose, the present invention provides a liquid crystal display device including:-an upper substrate;-a lower substrate is arranged with the upper substrate;-a liquid crystal layer, which is located between the upper and lower substrates;-a back wire group, which The light source is located outside the lower substrate and includes a light source including a plurality of cold-cathode fluorescent filaments. The cold-cathode fluorescent light has a rectangular wave-like structure. Compared with the prior art, the light source of the backlight module of this creation adopts a row of cold cathode fluorescent lamps with a rectangular wave structure, which divides the area between every two cold cathode fluorescent lamps into a plurality of small regions' and each The area has four parts of the light source, and the directions of the four light sources are not unique. Therefore, the backlight module has higher brightness and better uniformity, and the backlight module does not need to add cold cathode fluorescent lamps. Quantity, so the load will not increase. [Embodiment] Please refer to Fifth ® ′ for the schematic diagram of the county-level structure of the real money type. The backlight module includes a light source 100 and a light guide plate 101. The light source is a cold-cathode light source. It mainly includes a substrate cut and a plurality of cold-cathode fluorescent lamps 120. Please refer to FIG. 6, which is a schematic plan view of a backlight module light source according to the first embodiment of the present invention. The plurality of cold cathode material lamps are arranged in rows and rows—cold cathode labor lamps. The cold cathode fluorescent lamp of Wei Shui 12G Jiancai U⑽: and the cold cathode fluorescent lamp adopts a dome-shaped wave structure. By controlling the cold Yin lamp m: short, the sub-structure of the lake can be regulated. For the cold cathode The glory lamp M272108 120a and the cold cathode fluorescent lamp · The area surrounded by it is divided into a plurality of small areas, where each small area, such as the area YJ, is composed of cold cathode fluorescent lamps 12〇々, 12〇bi, 12〇b2 and 120b3 is composed of four parts, that is, the area VI has four parts of the light source, and the directions of the four light sources are not unique, that is, the area has two directions of light sources. Therefore, the backlight unit Higher brightness and better uniformity. In addition, since the number of cold-cathode fluorescent lamps 120 used in the light source 100 of the backlight module is small, its negative button is low and power consumption is small. Read the seventh picture at 4 meals, which is a plan view of the light source of the backlight module of the second embodiment. The backlight module light source 200 includes a substrate 21 and a plurality of cold cathode fluorescent lamps 220. A plurality of cold cathode fluorescent lamps 22 () arranged in rows form a cold cathode fluorescent lamp array. There is a certain gap between the plurality of cold cathode fluorescent lamps 22, and the cold cathode glory lamp 220 adopts a rectangular wave-like structure. By controlling the length of the cold cathode fluorescent lamp, the light sources can be arranged and combined into a lattice structure, and The cold-cathode fluorescent lamp 22 uses red, green (G), and blue-color monochromatic lamps, namely, the cold-cathode glory lamps 220a! And 220a2 emit red light, and the cold-cathode fluorescent lamps 22-bi and 22% 2 emits green light, cold cathode fluorescent lamps 22Cl and 220¾ emit blue light. By adjusting the driving voltage of cold cathode fluorescent lamp 22〇, the back group can emit colored light, and the backlight mode is bright. The liquid crystal display 7F device of the group does not require pure county # to display silk-colored images, and because the cold cathode fluorescent lamp 22G adopts a ship-like wave structure to align the light sources into a grid-like structure, it has- The two different colors have better color mixing effect, so the color mixing effect of the backlight module is better. Please refer to the second figure for a schematic structural diagram of the creative liquid crystal display device. The M272108 crystal display device 300 includes an upper substrate 310, a lower substrate 320 'disposed opposite to the upper substrate, a liquid crystal layer 330, and a backlight module 340.
