Example Embodiment

[0031] Example 1:

[0032] The steps of staggered arrangement of n LED light bars specifically include: n LED lights are located in the same plane for staggered arrangement, the LED lights on each LED light bar are equally spaced, and the same number on any two adjacent LED light bars The distance between the LED lights perpendicular to the scanning direction is 1 / n of the distance between two adjacent LED lights on the same LED light bar.

[0033] In this method, the number of n LED lights is not less than 2.

[0034] In this step, the LED lights on each LED light bar are located on the same horizontal line, and each LED light is equally spaced on the horizontal line.

[0035] In this method, when the LED display is rotated and scanned, the n LED strips are arranged at equal angles on the same horizontal plane, and the difference between the concentric circle radii of the LED lights with the same number on the n LED strips is the same LED strip. 1 / n of the distance between ...

[0039] Embodiment 2:

[0040] The steps of staggered arrangement of n LED light bars specifically include: n LED lights are located in the same plane for staggered arrangement, the LED lights on each LED light bar are equally spaced, and the same number on any two adjacent LED light bars The distance between the LED lights perpendicular to the scanning direction is 1 / n of the distance between two adjacent LED lights on the same LED light bar.

[0041] In this method, the number of n LED lights is not less than 2.

[0042] In this step, the LED lights on each LED light bar are located on the same horizontal line, and each LED light is equally spaced on the horizontal line.

[0043] In this method, when the LED display is scanned horizontally, n LED light bars are arranged at equal distances on the same horizontal plane, and the difference between the vertical distances between the LED lights with the same number on the n LED light bars is the same as the adjacent LED light bar...

Abstract

The invention discloses a method for improving the resolution ratio of POV scanning LED displayer. The method includes the steps that firstly, n LED lamp strips are distributed in a staggered mode; secondly, the LED displayer is scanned mechanically. The method has the advantages that the LED distribution method of the POV scanning displayer can increase the resolution ratio of the displayer under the same condition that LED lamp beads are packaged, gaps between images are reduced, and the brightness and fineness of the images are improved.

Description

technical field [0001] The invention relates to the improvement of a method for increasing the resolution of an LED display, in particular to a method for increasing the resolution of a POV scanning LED display. Background technique [0002] POV scanning LED display equipment uses horizontally moving or rotating LED light bars to realize image display by using the persistence of vision effect of the human eye. Traditional POV rotating scanning display devices use one or more columns of LEDs to rotate around their centers to display images in a flat space. Traditional POV horizontal scanning display devices use one or more rows of LEDs to move or rotate horizontally to display images, where LEDs with the same serial number on each row of LEDs are usually located on the same radius or on the same horizontal line. Due to the size limitation of the LED itself and the fixed frame of the LED package, there will be a large gap between two adjacent circles or lines in the display s...
