This identifies whether it is a single light source (SMD) or RGB cluster (DIP) configuration.
LED Display Pixel Pitch
This measures the gap between individual LEDs. The lower the number, the denser the LED array will be.
LED Display Pixel Matrix per panel
This numbers how many pixels are on the smallest replacement panel module.
LED Display Module dimension
This is the size of the smallest replacement panel module.
LED Display Enclosure Dimension
This refers to the size (or sizes) of enclosure the panels are supplied in. An enclosure might house a number of panel modules, as appropriate to the likely size of screen being constructed. Panels for big outdoor LED display, for example, come in big enclosures.
LED Display Enclosure Material
The usual choice is aluminium or steel.
LED Display Enclosure Weight
This weight is inclusive of the LED panels being enclosed. Multiplying it by the number of enclosures necessary to reach the required screen size gives you the screen’s overall weight.
LED Display Colour Greyscale (BIT)
The more bits on offer the more natural the image and colour accuracy.
LED Display Grey Scale per Colour (Level)
Higher specifications for this aspect offers greater colour accuracy and finer control. This affords more display possibilities without the problem of colour banding.
LED Display Refresh Rate
This measures the frequency at which the screen image is refreshed. You need this number to be high enough for a smart phone pic of the screen to look good. A lot of screens will fail this test.
LED Display Driving Type
This refers to the level of IC control.
LED Display Signal Transmission Distance
This measures the distances at which a signal from a source can be carried to the screen depending on the cable selection.
LED Display Brightness
This measures how brightly the screen can illuminate as a maximum.
LED Display Colour Temperature
A higher colour temperature means cool colours can become more vibrant.
LED Display Colour Contrast Ratio
The higher the ratio, the better the colour contrast will be. This aspect is affected not just by the choice of light emitting diode but also the housing.
LED Display Optimal Horizontal Viewing Angle
This identifies the area forward of the screen that will offer a vantage point for viewing.
LED Display Optimal Vertical Viewing Angle
This identifies the area above and below the screen that will offer a vantage point for viewing.
LED Display AC Input Power Maximum Value
This indicates the maximum power consumed per sqm as measured in watts.
LED Display AC Input Power Typical Value
This indicates the average power consumed per sqm as measured in watts.
LED Display Storage Temperature
This indicates the temperature range at which the product can be safely stored.
LED Display Operating Temperature
This indicates the temperature range at which the product can be safely operated.
LED Display Storage Humidity
This indicates the humidity range at which the product can be safely stored.
LED Display Operating Humidity
This indicates the humidity range at which the product can be safely operated.
LED Display IP Rating (Front/Rear)
This gives the IP rating noting any difference in rating between the front and rear of the enclosure.
LED Display Lifetime Typical Value
This gives the expected mean time to failure (MTF) for the product, expressed as hours of use.
LED Display Installation Type
This indicates whether the installation cabinet type is fixed or portable.
