Embodiment Construction

[0040] The invention provides a power transmission line, a light source module and a panel display device including the power transmission line. The power transmission line is mainly used to transmit power signals instead of data signals. In a preferred embodiment, the power transmission line is for connecting to a light-emitting device, such as a light-emitting diode light bar, etc., to form a light source module. In addition, such as figure 2 As shown, the light emitting device 100 has a first electrical connection terminal 110. The first electrical connection terminal 110 is preferably formed as a welding point for welding with the power transmission line 300; however, in different embodiments, the first electrical connection terminal 110 may also be formed as a male or female connector for connection with the power transmission line 300. Electric connection.

[0041] Such as figure 2 As shown, the power transmission line 300 is preferably formed in the shape of a long str...

Abstract

The invention discloses a power supply transmission line, and a light source module and a panel display device which contain the power supply transmission line. The power supply transmission line is connected to a light-emitting device so as to form a light source module and comprises a substrate layer, a power supply transmission layer, a metal shield layer, a first protective layer and a second protective layer, wherein the substrate layer is provided with a first surface and a second surface; the power supply transmission layer and the metal shield layer are respectively formed and arranged on the first surface and the second surface; the metal shield layer covers in a projection range of a transmission section in the power supply transmission layer; and the first protective layer and the second protective layer are respectively arranged on the power supply transmission layer and one surface of the metal shield layer back to the substrate layer so as to provide the protection for the power supply transmission layer and the metal shield layer.

Description

Technical field [0001] The present invention relates to a power transmission line and a light source module and a panel display device including the power transmission line; specifically, the present invention relates to a power transmission line with electromagnetic interference shielding effect and a light source module including the power transmission line and Panel display device. Background technique [0002] Liquid Crystal Display (LCD) is widely used in various electronic products such as computers, televisions, and mobile phones. The backlight module is one of the important components of the liquid crystal display device. The light source module used in the backlight module directly affects the efficiency and assembly cost of the backlight module. [0003] figure 1 Shown is a schematic diagram of a conventional liquid crystal display device. The liquid crystal display device includes a display panel 10 and a backlight module 30 provided on the back side of the display pa...
