It is measured in candela per square metre (cd/m²). Information about the brightness of the screen. 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.
#HP PIXEL SHARP DRIVER PROFESSIONAL#
It has a wider gamut than the sRGB (mainly in the cyan-green range of colors) and is widely used in professional printing. The sRGB color space covers about 72% of the NTSC color space.Īdobe RGB (1998) is a color space, developed by Adobe Systems in 1998.
#HP PIXEL SHARP DRIVER TV#
It is used in different devices such as printers, displays, TV sets, cameras, etc. SRGB is a color space, developed jointly by Hewlett-Packard and Microsoft in 1996. 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. Many professional monitors as well as some TVs have programmable internal LUTs allowing more control over the image. For example, LUT can be used to emulate/map different color spaces and gamma settings. There are different FRC algorithms.Ī LUT (Look Up Table) contains precalculated sets of values that are used to apply transformations to the input color data so that the resulting data meets certain (the desired) visual standard and color accuracy. 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. Information about the model of the panel used. Name of the manufacturer of the display panel. 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. Display Information about the main characteristics of the display - panel, backlight, resolution, refresh rate, etc.
