Description

Size class

Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches.

48.9 in (inches)
Diagonal

Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.

1243 mm (millimeters)
124.3 cm (centimeters)
48.937 in (inches)
4.0781 ft (feet)
Width

Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.

1196.7 mm (millimeters)
119.67 cm (centimeters)
47.1142 in (inches)
3.9262 ft (feet)
Height

Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio.

339.2 mm (millimeters)
33.92 cm (centimeters)
13.3543 in (inches)
1.1129 ft (feet)
Radius of curvature

There are curved displays, whose curve is part of a circumference (arc). In order to give more precise information about the curve of the screen, often the manufacturer provides data about the radius of this circumference. The smaller the radius, the larger the screen curve.

1800 mm (millimeters)
180 cm (centimeters)
70.8661 in (inches)
5.9055 ft (feet)
Panel manufacturer

Name of the manufacturer of the display panel.

Samsung
Panel type

There are various panel technologies. Each has its own specific features – viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.

QD-OLED
Panel bit depth

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.

10 bits
FRC

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.

No
Colors

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.

1073741824 colors
30 bits
Aspect ratio

The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10.

3.556:1
Resolution

Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image.

5120 x 1440 pixels
Pixel pitch

The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen.

0.233 mm (millimeters)
0.0233 cm (centimeters)
0.0092 in (inches)
0.0008 ft (feet)
Pixel density

Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

108 ppi (pixels per inch)
42 ppcm (pixels per centimeter)
Display area

The percentage of the approximate area, taken by the active part of the screen, to the total front area.

91.49 % (percent)
DCI P3

DCI P3 is a color space, introduced in 2007 by the SMPTE. It is used in digital cinema and has a much wider gamut than the sRGB.

98 % (percent)
Brightness

Information about the brightness of the screen. It is measured in candela per square metre (cd/m²).

250 cd/m² (candela per square meter)
Peak brightness

Often even a higher peak luminance can be achieved under certain conditions. For example, when a smaller area/APL of the display is used for showing a bright object, when a bright object is displayed for a short time, etc.

1000 cd/m² (candela per square meter)
Static contrast

The static contrast shows the ratio between the brightest and the darkest color, which the display can reproduce simultaneously, for example, within one and the same frame/scene.

15000000 : 1
HDR

HDR expands the contrast ratio (peak luminance and minimal black levels) and color palette to achieve more details across the whole image – from the darkest parts to the brightest ones, which results in more realistic and life-like image.

HDR10
DisplayHDR True Black 400
Horizontal viewing angle

Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality.

178 ° (degrees)
Vertical viewing angle

Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.

178 ° (degrees)
Minimum response time

Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G).

0.03 ms (milliseconds)
0.0000 s (seconds)
Coating

Information about the type of coating of the display. There are different types of matte and glossy coatings, each of which has its own advantages and drawbacks.

Anti-glare/Matte
