Name of the company-manufacturer.

Designation of the model.

Other known designations of the model.

The year in which this model was announced.

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.

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.

sRGB is a color space, developed jointly by Hewlett-Packard and Microsoft in 1996. It is used in different devices such as printers, displays, TV sets, cameras, etc. The sRGB color space covers about 72% of the NTSC color space.

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.

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

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.

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.

The dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video.

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.

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

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

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).
