    1. WHAT IS THE PITCH?

    The pitch defines the distance between two pixels, expressed in millimeters. This fundamental measure determines the characteristics and the performances of LED screen.
    The smaller is the pitch, the shorter is the minimum viewing distance, the higher is the total number of pixels present on the screen (and therefore higher is the screen's cost per area).
    The bigger the pitch is, the longer the minimum viewing distance will be, the lower  the total number of pixels present on the screen (and therefore the screen's cost per area will be lower)
    The pixel pitch therefore determines the LEDs density, which is usually called Resolution.

     

    2. WHAT IS THE RESOLUTION OF A DISPLAY?

     

    The resolution is the number of pixels present on each square meter. The resolution is therefore opposite proportional to the pixel pitch: the smaller the distance between two pixels, the higher the resolution.

    Remember: The smaller the pitch - the shorter is the minimum viewing distance. The higher the total number of pixels present on the screen is - the higher is the quality image.

     

    3. WHAT IS THE VISIBILITY ANGLE?

     

    The visibility angle of a screen is by convention the angle within which the brightness of a display is equal to the 50% of the frontal luminosity. For example, a screen with 5000 NIT frontal luminosity (NIT = millicandels/sq) has a visibility angle equal to the angle by which the brightness is reduced to 2500 NIT. This visibility angle can vary depending on the LED and the technical features of the display


    4. WHAT ARE THE COLOR LEVELS?

     

    Previous the display process under 8 bit technology, that degrades the image during the video elaboration phase, are able to visualize 256 color levels for each of the three primary colors. This means that you are able to visualize 256 x 256 x 256 = 16, 8 millions colors in total.
    Our screens instead utilize a 16 bit technology for each color that allows us to manage the video without altering the quality in a perceptible way (so the human eye does not notice it). After this elaboration (called Gamma Correction) it is possible to visualize 65.000 color levels for each of the three primary colors. This means that it is possible to visualize 65.000 x 65.000 x 65.000 = 280 trillion colors in total.

     

    5. WHAT IS THE CONTRAST LEVEL?

     

    It is the difference between the light emitted by the display and the environmental light reflected by the screen surface. The lower the light reflected, the higher the contrast and therefore the cleanliness and naturalness of the images. To increase the contrast, we provided solutions with particular anti-reflex flyers that split the light and reflect it in different directions, increasing the visibility of the screen even in direct sunlight.

     

    6. WHAT IS THE REFRESH RATE AND WHY IS IT IMPORTANT?

     

    The refresh rate indicates the number of times that the image refreshes every second. The refresh rate is fundamental because it determines the image's quality: if it is too low, the human eye can see a flicker that causes headaches and can damage eyes. To provide a comparison, most of the TV monitors have a refresh rate of 50Hz and only few products of the last generation have a 100Hz refresh rate. Power Screens - screens have a 300 Hz refresh rate, which is almost triple of the most advanced cathode tube technologies. This measure is ulterior prove of Power Screens quality and state-of-the-art technology, a result of years of research in laboratories and in the field.
