Embodiment Construction

[0021] Please also refer to figure 2 , is a three-dimensional perspective view of the first embodiment of the circuit board with inductive function of the present invention. The circuit board 2 includes a board body 20 and electronic components distributed on the board body 20 . The electronic components include at least one inductor, and other electronic components, such as chips, resistors, capacitors, etc., can also be added according to requirements. The board body 20 has an upper surface 26 and a lower surface 28 , and a plurality of through holes 21 passing through the upper and lower surfaces 26 , 28 . The plurality of through-holes 21 are divided into two rows arranged in parallel, each row of through-holes is distributed continuously, and the distance between them is the same. Preferably, the two rows of through holes are staggered, that is, the first through holes 21a of the first row do not face the first through holes 21b of the second row, and it is preferable ...

Abstract

The invention discloses a circuit board as well as an electronic device and a liquid crystal display applying the same. The circuit board comprises a board body provided with a first surface and a second surface which are opposite; the circuit board is provided with a first row of through holes, a second row of through holes and leads passing through the through holes; the through holes pass through the first surface and the second surface; and the leads are crossed to pass through the first row of through holes and the second row of through holes to form a spiral structure. The circuit board needs no additional induction elements, thereby effectively reducing the manufacturing cost and also reducing the assembling cost of the circuit board. In addition, the diameter of each lead is smaller than the height of an inductor, thereby the size of the circuit board is effectively saved, and the circuit board as well as the electronic device and the liquid crystal display which both apply the circuit board are thinned.

Description

technical field [0001] The invention relates to a circuit board, in particular to a circuit board with inductive function and electronic equipment using the circuit board, such as a liquid crystal display. Background technique [0002] In recent years, the electronic products required by people are developing in the direction of lightness, thinness, shortness and smallness. For example, in the field of displays, liquid crystal displays have gradually occupied the mainstream of display products due to their advantages of light and thin size, small footprint, and low radiation, and are widely used in ultra-thin TV displays, notebook computer display screens, etc. A liquid crystal display generally includes a liquid crystal display panel, a circuit board and a backlight module. The backlight module provides light for the liquid crystal display panel. The circuit board provides display signals and electric energy for the liquid crystal display panel. [0003] A circuit board ...
