TV Wikipedia What are the types of daily television conversations?

With the advancement of science and technology and the development of the times, the kinds of televisions that consumers can reach in the market today are dazzling and varied. However, because most consumers do not know enough about the types of televisions, how are they? When choosing a more suitable TV, it is full of endless confusion, but it does not matter, Xiao Bian meticulously sums up the following for everyone, I hope everyone can gain from it.

First, LCD TV (LCD)

Concept: As the name suggests, LCD TVs are televisions that use LCDs for display devices.

Principle: Use a backlight source, that is, a fluorescent lamp, to project a light source. The light source passes through a polarizer and then passes through a liquid crystal material, resulting in a change in arrangement of the liquid crystal molecules, thereby changing the angle of light passing through the liquid crystal and thus changing on the liquid crystal panel. There are different shades of color display. The liquid crystal display monitors the state of the liquid crystal molecules through the electrodes on the display screen to achieve the display purpose. Even if the screen is enlarged, its volume will not increase in proportion to the weight, and the weight is much lighter than the conventional display of the same display area. The weight of the LCD TV is about 1/3.30 inches less than that of the conventional TV. Compared to the old-fashioned CRT TV, it consumes more power. However, if it exceeds 30 feet, it will consume more power, and the screen will be larger and consume more power. The LCD TV has a clear and distinct picture, brilliant colors, high resolution, and high resolution. The static picture is the best. LCD TVs have a longer service life, and the average life of LCD TVs is about 50,000 hours. However, there are still disadvantages such as slow response speed, small viewing angle, poor color reproduction in pure black, and high manufacturing cost. Suitable for use in bedrooms or close to the room.

Second, plasma TV (PDP)

Concept: Plasma Display Panel (PDP) refers to the PDP (Plasma Display Panel), which is based on a mixture of two thin glass plates filled with a mixture of gases, and a voltage is applied to generate an ion gas, and then the plasma gas is discharged to react with the phosphor in the substrate to generate color. A color TV designed by the principle of video.

Principle: The use of inert gas electron discharge, generated by ultraviolet excitation of the coated red, green and blue fluorescent powder, showing a variety of colored light spots. With a slim body, light weight, large screen, colorful, clear picture, high contrast and brightness, fast response, low distortion, space-saving, play the best dynamic picture features. The emergence of the PDP has led to great changes in the development and application of medium-to-large sized (approx. 40 to 70) monitors. With its ultra-thin volume and weight far smaller than traditional large-size CRT TVs, it has high resolution, freedom from magnetic fields, and wide viewing angles. Active lighting and other advantages than TFT-LCD, fully meet the needs of light, thin, short and small multimedia products. However, there are still some disadvantages such as large power consumption, large heat output, unfavorable playback of still images for a long time, and high manufacturing costs. Suitable for viewing large rooms that are a long way away, such as in the family's large living room.

Third, LED LCD TV

Concept: Strictly speaking, LED TV refers to a TV that uses LED (Light Emitting Diode) as a display device. It is generally used for low-precision display or outdoor large screen. At present, the strict name of the LED TV that is commonly referred to in the home appliance industry in mainland China is “LED backlight LCD TV”, which refers to a LCD TV with LED as a backlight source, and is still a type of LCD.

Principle: It replaces the traditional fluorescent tube with LED light source, the picture is better, the theoretical life is longer, the production process is more environmentally friendly, and the liquid crystal display panel can be made thinner.

Fourth, OLED TV (OrganicLightEmittingDisplay)

Concept: An organic light emitting diode display refers to a technique in which an organic semiconductor material and a light emitting material emit light under current-driven conditions and realize display.

Principle: It has ultra-light, ultra-thin (thickness can be lower than 1mm) features, and has high-definition, high brightness, viewing angle, fast response (about 1000 times the speed of the LCD), can be bent and so on. OLEDs have low manufacturing cost and can display perfect video, and have been recognized as the most promising next-generation display technology in the industry.
