115" TCL 115QM891G - Specifications

Name of the company-manufacturer.

Name of the series, which the model belongs to.

Designation of the model.

The year in which this model was announced.

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.

Name of the manufacturer of the display panel.

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.

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.

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.

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.

sRGB is a color space, developed jointly by Hewlett-Packard and Microsoft in 1996. It is used in different devices such as printers, displays, TV sets, cameras, etc. The sRGB color space covers about 72% of the NTSC color space.

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.

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.

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.

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.

Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality.

Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.

Information about the type of coating of the display. There are different types of matte and glossy coatings, each of which has its own advantages and drawbacks.

The vertical frequency/refresh rate shows how many times in a second the image on the screen is refreshed.

Frame interpolation technologies differ according to the manufacturer and each has its own specific name.

The frame interpolation value as provided by the manufacturer. This value must not be confused with the refresh rate of the screen.

Some manufacturers name commercially the measurement unit of their own interpolation technologies as to denote the degree of interpolation. Very often the measurement unit is an abbreviation of the frame interpolation technology in use.

Permissible voltage tolerance in a 110-volt electric system.

Permissible voltage tolerance in a 220-volt electric system.

Requirement regarding the alternating current frequency in the electric system.

Information about the colors, in which the specific model is offered to the market.

Information about whether there is a possibility for wall mounting according to the VESA Mounting Interface Standard (MIS).

There are many various interfaces under the VESA standard, which differ in the size of the brackets, the distances between the screw holes and their number.

Information about whether the stand can be dismounted. Usually, this is required for wall mounting.

Information about the TV tuners, which the current model is equipped with.

Brand name of the processor trademarked by the manufacturer.

The software instructions are performed by the CPU cores. The higher number of cores allows for the parallel (simultaneous) processing of more instructions and achieving higher performance. There are various processors equipped with 1, 2, 4, 6, 8, and more cores.

The operating systems of the smart TV sets feature user interface technologies for navigation and other ways of interaction with the smart TV - installing applications, internet browsing, video calls, sharing content with other users, playing videos and music, etc.

The speaker is a device, which converts electrical audio signals into acoustic vibrations resulting in corresponding sounds.

The subwoofer is a type of loudspeaker used for the reproduction of low-pitched audio frequencies (20-300 Hz).

Information about the network technologies and standards supported by the model, which allow for it to connect to and communicate with other devices.

Information about the available connectivity ports, slots and interfaces such as USB, infrared port, SD card slot, audio/video and network interfaces, etc.

Information about additional software features, technologies, functions and services of the model.

Information about some of the main accessories included in the standard packaging of the current model.

Information about other features of the current model, which are important and have to be specified.
