Eskimo Matsushita has announced that the new LCD panel they have developed has exceeded the black level limit, and the contrast ratio can reach a staggering 1,000,000:1. If this is true, LCD panels will no longer be at a disadvantage in the war against OLEDs.
One of the biggest features of OLED panels is the perfect black level, which is also considered to be one of the most important factors in determining picture quality. Because you want to show excellent contrast, you must first have a black bottom "canvas." Since the OLED panel can independently control the switching of pixel points, even if its brightness does not reach the LCD level, high contrast can be achieved by displaying pure black.
In contrast, LCD panels rely on the extreme brightness of LED backlights to achieve high contrast. Because its pixels can't completely obscure the light that comes from behind, it can't show pure black. This is why LCD TVs have a halo effect when displaying bright objects in dark backgrounds.
But TV makers did not try to solve this problem, but instead turned to new technologies that could pare or even surpass OLEDs, such as Samsung's QLED panel based on quantum dot technology.
But now, Panasonic claims that it has developed a technology that can adapt to the current LCD panel and provide a perfect black level while achieving the highest brightness of 1000 nits.
According to the introduction, this new type of IPS LCD panel incorporates a new light modulation layer behind the conventional display unit, which filters out light from the backlight and thus acts as an additional switch to control the pixels individually.
When working with high-density backlights, this technology can provide 600 times the contrast of ordinary LCD panels, while also completely eliminating the problems of light leakage, halo and black ash. Compared with other types of LCD panels, IPS can also bring a wider viewing angle.
Although today's LCD TVs are already using local dimming to control the individual areas of the screen, Panasonic's pixel-by-pixel control provides better viewing. For now, Panasonic will first apply this technology in commercial areas such as live broadcasts, video productions, medical displays, and automotive displays, but consumer-grade TV will soon follow this technology.
If the actual effect of this technology is in line with Panasonic's publicity, it will likely shake the entire TV market. Currently, the cost of OLED panels is still high, and mass production is also difficult. QLED TVs require new production equipment and processes. However, Panasonic said that traditional LCD panel production equipment can be used to make its own new type of panel, which also maintains a lower production cost, and does not require additional adjustments to the production equipment.
Panasonic said that the new LCD panel will begin trial production in January next year, and we believe we will see more relevant information at the CES next year.
