LED Screen Pixel Pitch

If you need to define the pixel pitch of LED Screen (pitch of light-emitting diodes), and you do not have any ruler, you can start the program on your smartphone, put the gadget to the screen and press a just few keys ... and the pixel pitch is defined! The process is reduced to the task of visual combining of screen LEDs and the grid pitch of your smartphone display. You can also change the type of the grid by clicking on the figures.
