    ✅ Factors affecting the choice of LED screen

    The LED screen on the market today is quite diverse, so to be able to choose a Led screen suitable for your purposes, customers need to pay special attention to the following issues:

    ✔ Purpose of using Led Screen

    The purpose of the use is the most important factor in choosing a Led screen, when you determine the purpose of your Led screen, you will know what you need and what effects you will get from the LED screen. That Led screen.

    For example: To install an LED screen to watch movies, watch football in your home, you need to choose a type of Led Screen with high resolution to meet images and videos when watching in HD, Full HD or 4K.

    And if you want to install LED advertising screens for your store or company, then just choose the LED screens with the right resolution to meet your needs.

    Therefore, each different purpose of use will have different types of suitable LED screens.

    ✔ Led screen installation location

    Customers must determine the location they want to install is indoor or outdoor, this is quite important to be able to choose the type of Led: indoor LED screen (indoor) and LED screen outdoors (outdoor).

    Indoor installation location: If you want to install Led screens inside your home or in places with a discreet roof, you should choose the types of indoor Led Screens, here are some suggestions on the types of screens: Indoor LED screens are commonly used today:

    Led screen P3.91 indoor

    P3 Indoor Led Display

    Led Screen P2.5 Indoor

    Led Screen P2.0 Indoor

    Outdoor installation location: Installing an outdoor LED screen requires a fairly high brightness to display images and videos under the sun without being affected. Here are some suggestions for screen types. Outdoor led on the market today:

    Outdoor P6 Led Screen

    Outdoor P5 Led Screen

    Led Display P4.81 Outdoor

    Led Display P3.91 Outdoor

    In addition to the Led screens that we have suggested, there are many different types of Led screens, but depending on the purpose of use, customers can choose the following type of Led screen accordingly.

    ✔ Determine the size and viewing distance to choose the type of Led screen

    Determine size based on resolution:

    You can see that each Led screen will come with a letter "P" and a number on the back, "P" here means Pixel Pitch (distance between pixels), and the number behind is The distance between pixels is in mm For example An indoor P4 Led screen, it means that this screen has a distance of 4mm between pixels, the lower the distance between pixels, the higher the resolution of the screen. The higher the LED screen.

    Based on the distance between the pixels, you will calculate the size of the led screen you want to use, to give the desired image resolution, by multiplying the resolution by the parameter on the side. After the "P" of each type of Led screen, here are some current standard viewing resolutions:

    The LED screen meets the basic display resolution of (800 x 600 pixels).

    Led screen meets HD standard, has a resolution: (1280 x 720 pixels)

    Full HD standard LED screen, resolution: (1920 x 1080 pixels)

    Standard 4K LED screen with resolution: ( 4096 x 2160 pixels)

    To calculate the size of the Led screen based on the resolution we mentioned above, you can apply the following calculation:

    Led screen size (m2)= (Horizontal resolution x Pixel pitch) x (Height resolution x pixel pitch)

    For example, P3 indoor Led screen displays an HD resolution of 1280 x 720 pixels, you will calculate as follows:

    (1280 x 3) x (720 x 3) mm= 3840mm x 2160mm= 8.3m2, which means that the P3 Led screen to display HD images must be 8.3m2.

    Determine the type of Led screen based on the available size:

    If you already have an existing Led screen size and are wondering which type of Led screen to choose, try our calculation method:

    Led screen type “P”= (Led screen width size (mm) / Horizontal resolution) x (Dimension height (mm) / Height resolution)

    For example: If you want to install a Led screen to watch movies indoors with Full HD resolution (1920 x 1080 pixels) with dimensions: 3m x 2m

    Then the type of Led screen you need to choose is the indoor Led screen type

    And there is a matching “P” as follows:

    P= (3000mm/ 1920) x ( 2000mm/1080)= 2.7mm => P2.7

    However, at present, there is no P2.7 Led Screen on the market, so you can choose a Led screen with "P" that is almost equal to the value you calculated such as: P2.5 Indoor Led Screen or P3 indoor Led screen, these 2 types of the Led screen still fully meet the resolution you require, but the size will be a little different from your original expectation.

    Depending on the resolution and type of LED, there will be different corresponding sizes
    Depending on the resolution and type of LED, there will be different corresponding sizes

    Determine the minimum viewing distance and the best viewing distance:

    The calculation of the safe viewing distance is normally based on the size of the Led Screen. The larger the LED screen, the farther you should sit to avoid sitting too close, causing eye strain and discomfort. We will divide the viewing distance of the Led screen into the following 2 categories:

    Minimum View Distance (MVD): is the distance at which the human eye perceives a cluster of LED pixels as a single dot. Calculated by the following formula: Minimum viewing distance = distance between pixels x 1000mm


    OVD (Optimum View Distance): is the distance at which the human eye can no longer perceive each pixel. Calculated according to the following formula: Best viewing distance = distance between pixels x 2000mm

    Led screen viewing distance
    Best viewing distance OVD for Led screens

    You can refer to some suitable viewing distances and sizes of each type of Led screen that we suggest below:





    MVD (M)
