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.
|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)|
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.
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.
|3840 x 2160 pixels|
Ultra HD (UHD) / 4K / 2160p
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.
|0.315 mm (millimeters)|
0.0315 cm (centimeters)
0.0124 in (inches)
0.001 ft (feet)
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.
|80 ppi (pixels per inch)|
31 ppcm (pixels per centimeter)
The percentage of the approximate area, taken by the active part of the screen, to the total front area.
|93.45 % (percent)|
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.
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.
|95 % (percent)|
Information about the brightness of the screen. It is measured in candela per square metre (cd/m²).
|500 cd/m² (candela per square meter)|
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)|
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.
|5000 : 1|
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.
