Problems solved by technology

[0002] A liquid crystal display device includes multiple PCB boards, such as a power supply board, a main control board, an interface board, a key board, and a remote control board, etc., and some PCB boards are equipped with many circuits and components. The design trend of liquid crystal display devices is becoming more and more Thin, the PCB board design trend is also getting thinner and smaller, and the area is getting smaller and smaller. As a result, the layout of components on the PCB board is becoming more and more dense, and the heat dissipation area is insufficient, resulting in the temperature of some components being too high, which affects the PCB. The performance of the board, especially components with high heat generation such as ICs and MOS tubes on the power board and the main control board, are more likely to be damaged due to excessive temperature, and it is necessary to further improve the heat dissipation performance of the PCB board

Embodiment Construction

[0020] The invention discloses a liquid crystal display device, which includes a PCB board. The PCB board can be a power supply board, a main control board, or other PCB boards with high-heating components. The high-heating components can be ICs. , MOS tubes, etc., as an embodiment one of the PCB board for the liquid crystal display device, such as figure 1 and figure 2 As shown, the PCB board includes a front side and a back side. The front side of the PCB board is a surface where components are densely arranged, and the back side is a surface where components are not densely arranged. The components with high heat generation are arranged on the front side of the PCB board. The back side is provided with jumpers for heat dissipation, and the jumpers are connected with the terminals of components with high heat generation.

[0021] The front of the PCB board of the present invention is a densely arranged surface of components, and the back is a densely arranged surface of no...

Abstract

A PCB for a liquid crystal display device and a liquid crystal display device. The PCB comprises a front surface where components are densely arranged and a back surface where components are not densely arranged. A radiation jumper (2) connected to a pin of a component (1) is disposed on the back surface of the PCB.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and more specifically relates to a PCB board for a liquid crystal display device and a liquid crystal display device. Background technique [0002] A liquid crystal display device includes multiple PCB boards, such as a power supply board, a main control board, an interface board, a key board, and a remote control board, etc., and some PCB boards are equipped with many circuits and components. The design trend of liquid crystal display devices is becoming more and more Thin, the PCB board design trend is also getting thinner and smaller, and the area is getting smaller and smaller. As a result, the layout of components on the PCB board is becoming more and more dense, and the heat dissipation area is insufficient, resulting in the temperature of some components being too high, which affects the PCB.
