Background technique

With the increasingly sophisticated liquid crystal display technology, liquid crystal display panels have been widely used in consumer electronic products such as digital cameras, personal digital assistants (PDAs), mobile phones, and flat-screen thin TVs. The backlight module is one of the key components of the liquid crystal display, which is arranged on the back of the liquid crystal display panel to provide the light source required by the liquid crystal display panel.

Generally speaking, the backlight module usually includes a plurality of cold cathode fluorescent lamps (CCFL) arranged in parallel, and a combination of various optical components (such as diffuser plates, prisms, etc.) to provide a high-quality and uniform light source for the LCD panel . Among them, the cold cathode fluorescent lamp needs a voltage converter (inverter) to supply high-voltage current and voltage, so as to apply the high-frequency voltage to the lamp wires at both ends of the cold cathode fluorescent lamp, so that the internal discharge of the cold cathode fluorescent lamp is generated. Ultraviolet light excites the phosphor powder formed on the inner wall of the cold cathode lamp, thus producing visible light.

However, since the voltage converter cannot simultaneously provide the driving voltage required by multiple CCFLs connected in parallel, otherwise the capacity of the ballast in the voltage converter will be unstable, resulting in uneven brightness of the CCFLs. Basically, each cold-cathode fluorescent lamp needs to be electrically connected to different voltage converters to be driven by independent wires. This limitation makes the casing design of the liquid crystal display and the configuration of internal components of the backlight module difficult.

Moreover, because the known design requires multiple voltage converters, it cannot meet the current market requirements for liquid crystal displays that are thin and short, and increases the cost of liquid crystal displays, and the voltage converters are high-frequency components, so it is easy to generate electromagnetic interference and affect the liquid crystal display. normal operation.

The cold cathode lamp tubes 11 and 12 are in the same manner. Therefore, the adjacent electrode ends of each cold cathode lamp tube are connected by a first composite conductive socket member 21, so that the cold cathode lamp tubes 11, 12, 13, 14 are connected in series to form a quadrilateral cold cathode lamp tube group 100.

Referring to FIG. 4, the quadrilateral cold cathode lamp group 100 has a first electrode end 1a (the first electrode end 1a is the other electrode end of the cold cathode lamp tube 11), and the first electrode end 1a is electrically conductive through the second compound. The socket member 22a and the wire 3a are connected to the voltage converter 4 in FIG. 1 . The second composite conductive socket member 22a has a lamp tube socket surface 221 and a wire socket surface 222, and the lamp tube socket surface 221 is provided with an accommodating hole 213 (compared with the accommodating hole of the first composite conductive socket member 21 213), the wire socket surface 222 is provided with a wire insertion hole 216, the accommodating hole 213 includes a lamp guide wire accommodating section 213a and a lamp tube accommodating section 213b, the wire insertion hole 216 includes a penetrating segment 216a and an intervening segment 216b.

Similarly, the wire insertion hole 216 penetrates the insulating layer 215 and opens into the conductive layer 214, that is, the penetration section 216a of the wire insertion hole 216 penetrates the insulating layer 215 and opens into the conductive layer 214, and the wire insertion hole The insertion section 216b of 216 is opened in the conductive layer 214 .

The accommodating hole 213 of the second composite conductive socket member 22a is used to accommodate the first electrode terminal 1a of the quadrilateral cold cathode lamp tube group 100, that is, the first electrode terminal 1a is just accommodated in the second composite conductive socket member 22a in the accommodation section 213a of the accommodation hole 213 of the lamp guide wire and contacts the conductive layer 214, and one end of the lamp body of the cold cathode lamp 11 is accommodated in the accommodation hole of the second composite conductive sleeve member 22a 213 in the lamp housing section 213b. The wire insertion hole 216 is used to accommodate the wire 3a. The wire 3a has a head end 31a. The insertion section 216b makes the wire 3a contact the conductive layer 214 of the second composite conductive sleeve member 22a.

The two composite conductive sleeve members 22b and the wire 3b are connected to the voltage converter 4 in FIG. 1 . The structural design of the second composite conductive sleeve member 22b is substantially the same as that of the aforementioned second composite conductive sleeve member 22a, so the same components are marked with the same component numbers for correspondence. The difference is that the wire socket surface 222 of the second composite conductive socket member 22 b is opposite to the lamp tube socket surface 221 , and the wire insertion hole 216 is opened on the wire socket surface 222 .

And the accommodating hole 213 of the second composite conductive socket member 22b is used to accommodate the second electrode terminal 1b of the quadrilateral cold cathode lamp tube group 100, that is, the second electrode terminal 1b is just accommodated in the second composite conductive socket member 22b in the accommodation section 213a of the accommodation hole 213 of the lamp guide wire and is in contact with the conductive layer 214, and one end of the lamp body of the cold cathode lamp 14 is accommodated in the accommodation hole of the second composite conductive sleeve member 22b 213 in the lamp housing section 213b.

Since the quadrilateral cold-cathode lamp group 100 is composed of cold-cathode lamps 11, 12, 13, and 14 connected in series, only two wires 3a, 3b are needed to connect to the voltage converter 4, which simplifies the distribution of the lamps. The number of lines can also simplify the circuit design of the voltage converter 4 (only a single set of output voltage is required), and there will be no problem of uneven luminous efficacy among the cold cathode lamps 11 , 12 , 13 , and 14 .
