"Call board" OLED? ULED technology TV products turned out

When OLED TVs were still in sight, and the price of 4K TVs fell sharply, halfway through the process, the technology products known as ULED (abbreviation of Ultra-LED) were born. It is reported that the technology is comparable to OLED, and the price of the product is lower than that of 4K TV.

It is reported that the main difference between the 4K ultra-high-definition TV display and the FHD TV on the market is that it only stays at the resolution of the LCD screen. The high-definition quality of the ultra-high-definition display is still far from being fully demonstrated.

Liu Weidong, who presided over the drafting of IEC international backlight standards, introduced that ULED can be compared to OLED in terms of dynamic contrast and moving picture performance, and has certain advantages over OLED in terms of power consumption and brightness. At present, ULED "liquid crystal display method and liquid crystal display device technology" has been granted patents in the United States and Europe.

Compared with ordinary LED TVs, ULED TVs greatly improve the display performance in high contrast, high color gamut, high definition and faster speed through system software and hardware optimization.

The reporter learned that ULED display technology has improved image quality through technological innovation, and the panel cost has not increased much. Therefore, the price of ULED TV is much smaller than that of OLED. Take the latest 65-inch ULED TV sold by Hisense as an example, its price is only 20,000 yuan. Samsung, LG's OLED TV, even 55 inches, the former price of 55,000 yuan, the latter reached 60,000 yuan, not popular prices. Therefore, the price is "less than 4K TV", just a gimmick. However, as the market expands, the price of ULED TVs is expected to decline rapidly.
