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. 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. Often even a higher peak luminance can be achieved under certain conditions. It is measured in candela per square metre (cd/m²).

Information about the brightness of the screen. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc. The type of backlight determines the image quality and the color space of the display. The backlight is the source of light of the LCD display panels. The percentage of the approximate area, taken by the active part of the screen, to the total front area. With the decrease of the display size and the increase of its resolution, the pixel density increases. Information of the number of pixels in a unit of length. 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. The pixel pitch shows the distance from the centers of two neighboring pixels. A higher resolution allows the display of a more detailed and of higher quality image. Information about the number of pixels on the horizontal and vertical side of the screen. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. The ratio between the horizontal and the vertical side of the display. 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. 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. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. They provide 18-, 24-, and 30-bit color, respectively.įrame Rate Control (FRC) is a method, which allows the pixels to show more color tones. The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. The image quality depends directly on the type of the display panel used. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc.

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

If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.Īpproximate height of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.Īpproximate width of the display. Often this is the rounded value of the actual size of the diagonal in inches.Īpproximate diagonal size of the display. Size class of the display as declared by the manufacturer.
