The lifespan of an LCD TV is generally longer than that of similar-sized plasma televisions. Some manufacturers even claim that their LCDs can last upwards of100,000 hours when used continuously under controlled conditions (e.g., in a room with "standard" lighting conditions and 77° temperatures throughout).
Compared with traditional color TVs, the advantages of LCD TVs are mainly manifested in the following aspects:
The image resolution is high, generally speaking, it can reach 1024×758 pixels, which fully meets the requirements of future high-definition digital TV
The body is light and thin, with a thickness of less than 4 cm, which is only 1/2 to 1/3 of the thickness of a plasma TV, and about 1/10 of the thickness of an ordinary CRT TV
The appearance is stylish and beautiful, which is in line with the aesthetic taste of contemporary people, and is especially sought after by the younger generation
Long service life, generally reaching more than 50,000 hours. Calculated as 8 hours a day, it can be used for 17 years, which is longer than ordinary CRT color TVs.
Environmental protection and energy saving, LCD TV adopts progressive scan and dot matrix imaging, the image is flicker-free, and will not cause harm to human eyes. The power of 21-inch LCD TV is 40 watts, and the power of 30-inch LCD TV is 120 watts, which is more power-saving than ordinary CRT TVs.
Since LCD TVs need to be filled with liquid crystals, as the size increases, the difficulty and cost of filling will greatly increase, so the industry's judgment on the development direction of plasma and LCD: LCD TVs are developing towards small and medium screens, and plasma TVs are developing towards large screens. .
