Problems solved by technology

Due to the size limitation of the LED lamp itself and the fixed frame of the LED lamp package, there will be a large gap between two adjacent circles or lines in the display screen, and when using the same packaged LED lamp, the resolution is relatively limited, and the close-up Obvious graininess

Embodiment 1

[0032] The steps of staggered arrangement of n LED light strips specifically include: n LED lights are located in the same plane for staggered arrangement, the LED lights on each LED light strip are evenly spaced, and the same number on any two adjacent rows of LED light strips 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 equidistantly distributed on the horizontal straight line.

[0035] In this method, when the LED display is rotated and scanned, n LED light strips are arranged on the same horizontal plane at equal angles, and the difference in the radius of the concentric circles where the LED lights with the same number on the n LED light strips are located is 1 / n of th...

Embodiment 2

[0040] The steps of staggered arrangement of n LED light strips specifically include: n LED lights are located in the same plane for staggered arrangement, the LED lights on each LED light strip are evenly spaced, and the same number on any two adjacent rows of LED light strips 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 equidistantly distributed on the horizontal straight line.

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

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...
