Embodiment 1

[0032] The present invention is a kind of printed circuit board for electronic display LED illuminant such as figure 1 figure 2 As shown, the printed circuit board is printed on the substrate, and the substrate is divided into two rows and eight equal parts into a unit 01 for sequential arrangement to prepare the LED power connector contact point 02, and each row is A area 15, B area 16, and C area 17. , D area 18 and the other row are a area 11, b area 12, c area 13, d area 14, wherein the LED power connector contact point 02 is set in the three areas of A area 15, C area 17, and b area 12, Each unit 01 has five positive and negative LED power connector contact points 02, four LED power connector contact points 02 in area A15, and three LED power connector contact points in areas C and b respectively. The upper and lower adjacent units are dislocated by two equal divisions, and the area of ​​each eighth division in one unit 01 is equal to the area of ​​an LED chip; there is...

Embodiment 2

[0034] The present invention is a kind of printed circuit board for electronic display LED illuminant such as figure 1 figure 2 Shown, the present invention is used for the circuit diagram corresponding to an LED chip on the printed circuit board of electronic display LED illuminant as image 3shown. The LED power connector contact point 02 on the printed circuit board includes a positive LED power connector contact point 21 and a negative LED power connector contact point 22. Each LED chip 00 corresponds to a positive LED power connector contact point 21 and a negative LED power connector contact point. 22. The contact point 21 of the positive LED power connector is directly or indirectly connected to the positive pole of the power supply 05, and a current control unit 08 is further included between the positive pole LED power connector contact point 21 and the positive pole of the power supply 05. The current control unit 08 includes a power switch 07, The resistance valu...

Abstract

The invention discloses a printed circuit board for an LED illuminant of an electronic display device. The printed circuit board comprises a substrate and a printed circuit which is printed on the substrate. Sequence arrangement is performed on the substrate in a manner than eight equal parts in two rows form one unit, thereby preparing an LED power joint contact. Two adjacent units in the vertical direction are staggered by two equal dividing distances, wherein the area of each part in eight equal parts in one unit is equal with the area of one LED chip. In each unit, five anodes and five cathodes of the LED power joint contact exist. After the printed circuit board is connected with the LED illuminant, light emitting rate of the LED illuminant can be improved, and furthermore color saturation and brightness of the LED electronic display device can be improved.

Description

technical field [0001] The invention relates to a circuit board. More specifically, the present invention relates to a printed circuit board for an LED light emitter of an electronic display. Background technique [0002] Printed circuit board, also known as PCB circuit board, is a provider of electrical connections for electronic components. It has a history of more than 100 years since its invention. The main advantage of using circuit boards is to greatly reduce the current flow through layout design. Errors in wiring and assembly improve the yield rate of electronic components in the electrical connection process, and also make the process transform to industrial automation. Before the appearance of printed circuit boards, the electrical connection of electronic components relied on direct connection of wires to form a complete circuit, but at that time, circuit boards were only used as experimental tools and could not be mass-produced industrially. has taken absolute ...
