Most of the initial standards for plasma TVs and LCD TVs were 25,000 to 30,000 hours, and the lifetime of the new generation of plasma screens reached 60,000 hours. With the development of technology, the lifespan of plasma TVs may be further improved. LCD TVs are also exploring new light source technologies such as LEDs to extend their life.

2, performance indicators

The nominal brightness and contrast index of plasma TVs are higher than those of LCD TVs. The contrast ratios of plasma TVs are basically 3000:1, 4000:1, and 5000:1. The latest ones have reached 10,000:1, and the brightness is mostly 500cdm2~1000cdm2. ; LCD TV contrast index is basically between 400:1-1200, most of the brightness in the 400-800cmm2, only from the nominal indicators, plasma TV is higher than the LCD TV, I believe this is the plasma TV performance to LCD TV The origin of the argument.

3, display effect

The pixel sense of the plasma TV image is stronger, especially the product with a resolution of 852×480, and the LCD TV image is more delicate; in terms of color, the color of the LCD TV is generally saturated and somewhat warm. The color of plasma TVs is more natural and fresh.

4, resolution

Some people say that the resolution of LCD TVs is higher than the resolution of plasma TVs. This argument is not accurate. From the current products on the market, plasma TVs do have a number of products with a resolution of 852×480, but the market has already emerged. Plasma TVs with 1024 x 768, 1366 x 768, and 1024 x 1024 resolutions are well-suited for both computer image display and high-definition video display.

The resolution of LCD TVs on the market is relatively wide, ranging from 640x480, 1024x768, 1024x768, 1280x768 to 1920x1080.

1, thin and portable. The liquid crystal display achieves the purpose of display by controlling the state of the liquid crystal molecules through the electrodes on the display screen. Even if the screen is enlarged, its volume will not increase proportionally (only increasing the size does not increase the thickness, so many products provide a wall-hanging function, and can be more Space-saving) is about 1/3 the weight of traditional TV.

2, rich colors. LCD TV screens are structured and colorful.

3, large resolution, high resolution. The best resolution of the LCD screen is generally up to 1024X768.

4, green environmental protection. The liquid crystal display has no radiation, there is no screen flickering phenomenon, and it is not easy to cause visual fatigue.

5, low power consumption, long service life. The annual power consumption of 4.5 hours per day is used to replace the 32-inch CRT TV with a 30-inch LCD TV, which saves 71 kilowatts of electricity per year. The service life of LCD TVs is generally 50,000 hours, that is to say more than 20 years, much longer than that of ordinary TVs.

Disadvantages of LCD (liquid crystal display):

1. In response to the display speed, the response time of the LCD is relatively long, so the performance in dynamic images is not ideal.

2, display quality: LCD theoretically only significant 18-bit color, but the color depth of the CRT is almost infinite.

3. The viewing angle of the LCD is relatively small compared to the CRT display.

4, LCD display is relatively fragile and vulnerable to damage. This increases the difficulty of using and maintaining the LCD TV.

5, LCD TVs are more difficult to make in the process (mainly low-yield high-screen), and thus quotations are expensive.

Plasma TV is a TV with a plasma screen as a display component. Plasma TV is also called a “wall-mounted TV”. It is not affected by magnetic force and magnetic field. It has a slim body, light weight, large screen, bright colors, clear screen, and high brightness. , Small distortion, space saving and other features.

Plasma is now a mainstream flat-panel TV. Especially since the second half of 2004, the global demand for plasma TVs has gradually increased. Plasma and LCD, and the Three Kingdoms rear projection in the high-end TV market have a long history. It is still necessary to start from their own needs. For plasma TVs, the advantages and disadvantages are as follows:

(a) Advantages:

1, plasma has a very high contrast, as many plasma TVs can now reach 5000:1 or 10000:1, while the LCD can reach 1000:1 are more difficult;

2, plasma and good color display capabilities, its rich colors, up to 5 billion colors, while the liquid crystal is generally 16.77 million colors;

3, plasma response speed is very fast, plasma is a microsecond level, and LCD-TV is a millisecond level, a thousand times the difference of the entire three orders of magnitude. The nature of the LCD molecule itself determines that its response speed will never be less than 1 millisecond.

4, plasma has a long life, relative to rear projection and other large-screen TVs, plasma and liquid crystal have a long life. In general, it can reach a lifetime of 35,000 hours. The nominal service life of products such as Hitachi has reached 60,000 hours, while projection TVs such as rear projectors generally have a lifespan of only 5,000 hours, although there are manufacturers that specify their rear projection energy. Achieve 10,000 hours of life, but compare liquid crystal and plasma too short;

5, plasma has a very good visual range, unlike LCD, its viewing angle range is generally more than 160 degrees.

(B) Disadvantages

1. Although the plasma TV is thin, it is not very light;

2. If you allow it to display a unified screen for a long time, it may burn, so generally plasma TVs have to do screen protection display;

3, dark black level performance is weak;

4, because of its large screen, fragile, which requires us to be particularly careful in the process of transportation, installation and daily use;

5, the power consumption is relatively large, generally a 42-inch power consumption of 380W, like the 60-inch to reach 600W.
