Name of the manufacturer of the display panel. |
LG Display |
| 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. |
OLED |
| 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 |
| 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. |
No |
| Colors

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. |
99.5 % (percent) |
| Brightness
Information about the brightness of the screen. It is measured in candela per square metre (cd/m²). |
335 cd/m² (candela per square meter) |
| Peak brightness
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. |

| 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. |
1500000 : 1 |
| HDR
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. |
