Problems solved by technology

The existing outdoor double-side or three-side flip LED display, the circuit board installed inside it is generally rectangular, and the entire surface of the circuit board is a flat surface, which has certain limitations and poor flexibility during installation.
In order to ensure sufficient display brightness, relatively dense LED lights need to be installed on the circuit board. The distance between horizontally adjacent LED lights on the circuit board is generally equal to the distance between vertically adjacent LED lights, so that the displayed picture is sufficient. High brightness and clarity require a large number of LED lights, which increases production costs

Embodiment 1

[0011] Embodiment 1, the distance between adjacent LED lights arranged horizontally on the board body is twice the distance between adjacent LED lights arranged longitudinally on the board body.

Embodiment 2

[0012] Embodiment 2, the distance between adjacent LED lights arranged horizontally on the board body is three times the distance between adjacent LED lights arranged longitudinally on the board body.

[0013] Embodiment 2, the distance between adjacent LED lights arranged horizontally on the board body is four times the distance between adjacent LED lights arranged longitudinally on the board body.

[0014] The invention expands the distance between LED lamps, but ensures display brightness and clarity, and greatly reduces production cost.

Abstract

The invention discloses a circuit board, comprising a board body and LED (Light-Emitting Diode) lamps arranged on the board body, wherein distance between the LED lamps which are transversely adjacent on the board body is 2-4 times of the distance between the LED lamps which are longitudinally adjacent on the board body, and gaps are arranged at the two ends of the board body along a longitudinal direction. The circuit board disclosed by the invention has simple structure, the quantity of the LED lamps is reduced while the same brightness and definition are realized, and production cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to a circuit board, in particular to a circuit board mainly used in double-sided or three-sided LED display screens. Background technique [0002] At present, with the rapid development of science and technology, LED technology is more and more widely used in advertising, especially outdoor advertising. Existing outdoor double-sided or triple-sided LED display screens generally have a rectangular circuit board installed inside, and the entire surface of the circuit board is a flat surface, which has certain limitations and poor flexibility during installation. In order to ensure sufficient display brightness, relatively dense LED lights need to be installed on the circuit board. The distance between horizontally adjacent LED lights on the circuit board is generally equal to the distance between vertically adjacent LED lights, so that the displayed picture is sufficient. Brightness and clarity require a large number of LED lights...
