For the Chinese market, a TV is a long-term home appliance product, and it is very common to use it for 5, 10, or even more than 10 years. Therefore, if an OLED TV is used for 2 or 3 years, it will enter the "late stage of terminal illness". , which is clearly unacceptable. In fact, we don't have to worry too much about this. Although OLED TVs are just now on the market, in the past few years, OLED technology has improved by leaps and bounds, including lifespan issues.
OLED light-emitting materials can be divided into fluorescent materials and phosphorescent materials according to the type of light-emitting excitons, each with different luminous efficiency, specifically: the red light efficiency is 11cd/A, the life span is as high as 160,000 hours; the green light efficiency It can reach 30cd/A, and the life span is 60,000 hours; while the blue efficiency is only 8.7 cd/A, and the life span is only 23,000 hours. It can be said that blue is sickly, and it is also the root of the lifespan of OLED displays.
As an important household appliance, TVs are often used for a long time after purchase, so durability is very important. The reason why oled TVs have a limited lifespan is mainly because of the aging of its screen, it is mainly made of organic materials, and over time, oled TVs will become like oxidized juice.
Do OLED TVs have a lifespan of only 5000 hours? The 5,000-hour claim is probably from before 2013. The old data is not convincing. Just like when LCD TVs first came on the market, the price of a 40-inch TV was more than 1W. Now you can start with about 2,000 yuan. development and progress.
The current OLED TV can be watched for about 10 years according to the viewing time of 8 hours a day. And now people's TV time is basically concentrated in the evening, and they basically can't watch 8 hours, and it is very likely that they will automatically replace the TV after the TV is used for 6 or 7. The new technology at that time must be more advanced. Although the price of OLED TVs is high now, it seems that the picture quality is much better than that of LCD TVs.
OLED TVs use so-called quantum dot technology. They are actually semiconductor nanocrystals that can improve display brightness, contrast, and save power. This technology is different from the OLED technology currently promoted by LG Electronics, which still uses backlight technology. A Samsung Electronics executive said the comparison of OLED and QLED TVs is just to provide consumers with accurate information, not to discredit a rival.
