Description

Backlight module and lamp tube positioning seat with partition wall

technical field

The invention relates to a lamp tube positioning seat and a backlight module including the lamp tube positioning seat; specifically, the invention relates to a lamp tube positioning seat with a partition wall and a backlight module including the lamp tube positioning seat.

Background technique

Due to the thin thickness, light weight and portability of liquid crystal display panels (LCD Panel), compared with CRT displays, it has the advantage of low radiation, so that the demand for liquid crystal display panels has increased rapidly in recent years. Especially the backlight module (Backlight Module), which is one of the key components of the liquid crystal display panel. With the improvement of liquid crystal display manufacturing technology, the backlight module is developing towards the market direction of thinner shape, higher brightness and lower cost. In order to maintain the competitiveness of the liquid crystal display market in the future, developing and designing better backlight modules is the direction that needs to be worked hard in the future.

Generally speaking, current backlight modules generally use lamps such as cathode ray tubes as the backlight light source. As shown in FIG. 1 , a conventional direct-lit backlight module includes a backplane 10 , and a lamp tube connecting seat 30 is disposed on the backplane 10 . The lamp tube 50 is connected to the lamp tube connecting seat 30 on the inner surface of the backboard 10 , and then connected to the inverter (Inverter) 90 on the bottom surface of the backboard 10 through the wire 70 passing through the lamp tube connecting seat 30 . To save production cost and time, two lamp tubes 50 are usually connected to each lamp tube connector 30 , so two wires protrude from the back side of the lamp tube connector 30 and are connected to the inverter 90 at the same time.

The inverter 90 is usually disposed on a circuit substrate 95 , and the circuit substrate 95 is then locked on the bottom surface of the backplane 10 of the backlight module. In consideration of the size of the circuit board 95 , usually not all lamp tube connecting sockets 30 can be aligned with the corresponding inverters 90 . In order to smoothly couple the lamp tube 50 with the inverter 90 , it is often necessary to bend the portion of the wire 70 protruding from the bottom of the back plate 10 , so that adjacent wires 70 may be in contact. In addition, even if the position of the lamp tube connecting base 30 is aligned with the inverter 90 , the adjacent wires 70 may be bent due to force during the assembly process, resulting in contact. Since the wires 70 are used to conduct high-voltage current, when adjacent wires 70 are in contact, short circuits and sparks may occur. In addition, although generally the wires 70 are protected by an insulating sheath, the insulating sheath may be damaged. Therefore, when the adjacent wires 70 are in contact, the probability of failure of the backlight module as a whole is greatly increased.
