Display
Information about the main characteristics of the display - panel, backlight, resolution, refresh rate, etc.
| 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. |
21.5 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. |
546.1 mm (millimeters) |
| 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. |
476.64 mm (millimeters) |
| 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. |
268.11 mm (millimeters) |
| 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. |
IPS |
| 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. |
8 bits (6 bits + FRC) |
| 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. |
Yes |
| 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. |
16777216 colors |
| 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. |
1.778:1 |
| 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. |
1920 x 1080 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. |
0.248 mm (millimeters) |
| 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. |
102 ppi (pixels per inch) |
| Backlight 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. |
W-LED |
| NTSC (1953) The NTSC (1953) color space is introduced in 1953 by the FCC with the appearance of color television and has a wider gamut than the sRGB. |
72 % (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) |
| 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. |
1000 : 1 |
| Dynamic contrast 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. |
100000000 : 1 |
| 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. |
