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.

TN
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 (8 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.

1073741824 colors
30 bits
Aspect ratio

Ultra HD (UHD) / 4K / 2160p
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.

0.162 mm (millimeters)
0.0162 cm (centimeters)
0.0064 in (inches)

157 ppi (pixels per inch)
61 ppcm (pixels per centimeter)
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).

300 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.
