Selection
- Before buying a new TV, please read the energy label carefully.
- It is equally important to consider your TV viewing habits – either it will be switched on in the evening to watch news, soaps and films, or it will be used by a cinema fan, who is particularly interested in high quality. In the first case, the comparison of different modern TV screens will not make a significant difference; however, if high quality is important, it is worth investing and getting quality in the long run.
- One of the most important factors in choosing a TV is the type of screen. We have summarised the main advantages and disadvantages of different screen types.

Screen type |
Main advantages |
Main disadvantages |
|
LLCD or liquid crystal display. Pixels do not emit light; therefore, supplementary illumination is provided by light bulbs behind the screen (CCFL). The light passes through filters (polarisers) and then into a liquid crystal. |
Low weight. Lower costs. |
Poorer contrast. Narrower viewing angles. Lower image quality, especially in dynamic scenes. No distinct black colour. Increased screen thickness. |
|
Edge LED – LEDs are situated at the sides of the TV. Full LED – LEDs spread across the entire screen area. LED – light-emitting diodes. |
Higher contrast. Very good colour reproduction. Lower electricity consumption; however, note that Full LED TVs will have higher electricity consumption due to the placement of the LEDs. Much thinner compared to LCD TVs. |
Higher costs. The narrower viewing angle is more suitable for watching films and playing console games. |
|
QLED * – an improved version of LCD, LED achieved by adding a quantum dot enhancement film. Quantum dot – light-emitting diodes. *Quantum dot – light-emitting diodes. |
Significantly more brightness, livelier and more vivid images, especially in sunny rooms. High contrast value. Wider viewing angle. More pronounced shades of black and bright colours. A more affordable technology compared to OLED. |

OLED** – based on organic light-emitting diodes that are built into each pixel, which emits light independently. ** Organic light-emitting diodes.
|
Perfect contrast or colour variation – realistic image. Extra-wide viewing angle. Distinct black colour. Increased screen responsiveness, which ensures dynamic viewing. Higher energy efficiency. Lower electricity consumption. Very thin body. |
Higher costs. |
What else should be taken into consideration?
- The size of the TV screen also determines the electricity consumption, therefore you need to select a screen, the size of which suits the room. To calculate the optimum diagonal size of a TV screen in centimetres, the distance from the viewer’s position to the screen must be divided by three.
- We recommend choosing a TV with a built-in ambient light sensor, as this will automatically adjust the screen to the optimum brightness in a dark room, saving 30–50% on electricity.
- If you often forget to turn off the TV when it’s not being actively watched, or if you use it to listen to digital radio, you should choose a TV model that has a built-in occupancy sensor (the screen is automatically turned off when no one is near the TV) or a screen-off function, thus reducing your overall electricity consumption.
