- Energy consumption?;
The size of a TV matters a lot when making a purchase.You have to take into account the size or configuration of the room that will accommodate the television.It feels cramped when the TV is too big for the bedroom.Likewise, a small TV is not ideal for a large living room.For an Ultra HD TV, it is recommended to have a viewing distance of 1.3 times the diagonal of the screen.To put it simply, if the screen size is between 46 and inches, the reversing distance should be between 1.5 and 2 meters.As a reminder, the size of the TV diagonals is in inches, and 1 inch is equal to 2.54 cm.Despite its details, the size of a TV also depends on the use you want to make of it.Many people enjoy large screens in order to better enjoy the pleasure they offer.As for the panel technology, it is essential in the video quality of a screen. Today, televisions are equipped with different technologies: LED, Edge LED, Direct (Full) LED, OLED… Plasma and LCD screens have shown their limits and are increasingly rare.
The majority of televisions embed this technology.It is a backlighting system for the screen which is carried out using diodes (LED or Light-Emitting Diode).These replace the neon lights on LCD screens.Regarding Edge LED technology, the diodes are placed at the periphery of the screen.Unlike the Direct LED whose diodes are located behind the image in a uniform manner.We recognize certain strengths in LED technology:
- Enhanced contrast?;
- Bright colors?;
- Wide viewing angle?;
- Low power consumption.
In an OLED TV, each pixel is made up of a diode. And, each diode emits its own light. This makes a single screen made up of an almost infinite number of LEDs.There are many advantages:
- Excellent image quality?;
- Exceptional brightness?;
- Infinite contrast.
