Professional display: main differences from consumer TVs

From a technical point of view, a professional display is a regular screen consisting of a liquid crystal matrix, backlight, electronic components and a housing. In turn, the LCD matrix is ​​an array of liquid crystals enclosed between layers of a glass or polymer package and combined into subpixels of three basic colors: red, green and blue.

Higher image brightness

The typical brightness of household LCD TVs is 250-300 cd/m2. The brightness of LCD panels is much higher and can reach values ​​of 2000-2500 cd/m2. Increased brightness allows the use of professional displays in outdoor advertising and in natural light conditions.

Operating mode

Traditional TVs are rarely designed for round-the-clock operation. As a rule, the typical continuous operating time for a household TV is 6 hours, after which it is recommended to turn it off. Professional displays are capable of continuous operation 24 hours a day.

Resistance to matrix burnout

A static image displayed on the display screen for a long time leads to degradation of liquid crystals and the appearance of the so-called “shadow” – artifacts that remain on the screen even when there is no image on the screen. This happens because the constantly closed crystals on the matrix, blocking the light passing through it, heat up very much. In the case of household TVs, the components that make up the liquid crystals are less resistant to constant loads.

Professional displays are almost completely free of this drawback. Therefore, professional displays are better suited for demonstrating static content (airport schedule, logo, showcase, etc.).

Extended operating temperature range

Liquid crystals have an operating temperature range, beyond which they lose their properties. As a result, ordinary household TVs are not suitable for use in frost or heat. In particular, the effect of screen burnout in the sun is known, when, heated by direct sunlight to a temperature above 85°C, the screen irreversibly darkens, losing the ability to display an image.

• Professional displays can operate in much harsher temperature conditions without degradation of liquid crystals.
• Professional displays have a special protective coating on the front side of the case, which completely prevents the possibility of matrix burnout.

Arbitrary orientation

Unlike a regular TV, which is traditionally mounted in landscape orientation, professional displays can be installed in portrait mode without possible damage to the matrix.
