Why did television become "bent" after intelligence?


In addition to smart television, the appearance of curved, ultra-thin, laser, OLED TVs on the hardware, from this year, many TV companies began to "bend" the screen, launching equipped with intelligent, 4K and other curved TV. The statistics released by the China Electronic Chamber of Commerce today show that there are more than nine brands of over 40 curved TVs on the market, mainly 55 inches or more, and most have 4K ultra-high-definition display.

At the same time, the China Electronic Chamber of Commerce has issued guidelines for the purchase of curved cinema televisions, including compliance with surface television display performance evaluation specifications, outstanding color performance, sound quality, picture quality, chip processing and decoding capabilities, and telepresence experience. Includes 96% color gamut coverage, live presence, 4000R curvature, and more.


Li Jian, deputy chief engineer of the State Broadcasting and Television Product Quality Supervision and Inspection Center, said that the use of a curved LCD display panel with a curvature of 4000R improves brightness uniformity by 13%, flatness ratio by 44.6%, and distortion rate improvement by 63%. The curvature radius of the new generation of curved TV products is more curved than the previous generation.

"The more curved the TV screen, the more realistic the sense of being able to deliver the viewer." Shen Peng, director of product planning at Samsung SDC, said that the curved structure can obtain a larger display area in a limited space, so the viewing angle is wider. In addition, the contrast ratio of flat-screen TVs of the same size TV surface TVs is increased by 48%.

This is because the lens of the human eye is a convex lens, and the focal plane formed by the focal point of the convex lens is a spherical arc surface, not a true plane. "Long-term (2 hours) after watching the changes in the degree of flexibility of the human eye surface TV is less than flat-panel TVs, and the degree of human eye fatigue is less than that of flat-screen TVs," said Liu Xinshu, Ph.D. in Ophthalmology at Peking Union Medical College Hospital.


According to the data from relevant research institutions, the sales volume of curved TVs in the first quarter of this year was 59,000 units, an increase of 70 times year-on-year, and sales reached 983.81 million yuan, an increase of 40 times year-on-year. The market size in 2015 will reach 1.6 million units.

But at present, the price of curved TV is relatively high, and the relevant data shows that the price of the most mainstream 55-inch 4K smart flat-screen TV on the market is 6000-8000 yuan, and the average price of curved-surface TV is between 10,000 yuan and 16,000 yuan.

“With the increase in sales volume, curved TV prices will have a greater decline this year.” Lu Jiebo, secretary-general of the China Electronic Chamber of Commerce, said that the number of surface-mounted televisions is currently below 10,000 yuan.
