Experts say that buying OLED TV "four major risks" needs attention

too expensive

It is understood that the price of Samsung S9OLED TV is as high as 8999 US dollars. The price of the LG55EM9800 is as high as $14,999. Although LG's TV set was launched in July, it became the first similar product on the market, but it did not receive much attention because of the high price. It is estimated that LG will soon lower the price to the same level as Samsung.

The US CNET website said that their most recognized 55-inch plasma TV is the Panasonic TC-P55VT60, which is priced at only $2,700. The best 55-inch LED LCD TV that has been evaluated this year is the Sony KDL-55W900A, which is priced at only $2,300.

The new technology was born very expensive at first, but as demand increases and supply increases, prices will continue to fall. Since the release of 4KLED LCD TVs, prices have fallen sharply in just one year. The reasons include the strong entry of Chinese TV brands, and Sony, LG and other manufacturers have also made substantial price cuts.

However, the production of OLEDs is much more difficult than LED LCD TVs. Considering the production problems faced by OLEDs, such products are still unable to achieve the price of close to the people in the short term.

Burning screen

Experts also pointed out that OLEDs are easy to burn. As with plasma TVs and CRT monitors, if the image is left for too long, the OLED will leave the image on the screen for a short period of time, or even permanently. Although the probability of being specifically affected is currently uncertain, several examples have already occurred.

The most extreme example comes from the LG OLED TV set from Harrods, UK. According to a user of AVS Forums, this screen will even keep traces of burning screen two months ago. If set to the highest brightness, the screen will always leave a residual image of the directory.

If you have used an old OLED phone, such as the first generation of Samsung GalaxyS, you may have experienced this situation. Some icons will stay on the screen forever, and if the brightness of the screen is increased, it will be faintly visible.

Of course, plasma TVs will burn out in extreme cases, and there will be short-lived afterimages in normal use, but CNET still recommends these products. "Unless we see credible evidence, we believe that both plasma and OLED will be affected by this problem."
