South Korean manufacturers are leading a major shift in the global display market, with a growing emphasis on OLED technology as a replacement for traditional LCD panels. For over a decade, LCDs have dominated the TV industry due to their slim design and large screen sizes, gradually phasing out CRT TVs. However, starting in 2016, speculation about the end of the LCD era began to rise, as OLED emerged as a promising next-generation alternative. With features like self-luminous pixels, true color reproduction, zero input lag, infinite contrast, ultra-thin design, and flexible displays, OLED is seen as the future of high-end television screens.
South Korea, the world's largest panel producer, has been at the forefront of this transformation. LG Display recently shut down its fifth-generation P4 plant in Gumi, following the closure of its earlier 3.5-generation P2 line. The company plans to close its 4th-generation P3 plant by year-end. By 2020, LGD aims to invest $18.08 billion in OLED production, with new facilities such as P10 and E6 in Paju, E5 in Gumi, and an OLED plant in Guangzhou, China.
Samsung Display, another key player, has also been reducing its LCD capacity. Over three consecutive years, it closed one 7th-generation and two 5th-generation panel factories. This year alone, Samsung invested $8.8 billion to expand OLED production, converting some of its existing LCD lines into OLED manufacturing units. These moves signal a clear shift toward OLED across the Korean industry.
While the transition from LCD to OLED is accelerating, it’s unlikely that OLED will completely replace LCD in the near future. For now, LCDs still hold a strong position, especially in larger TV sizes where cost and pricing remain critical factors. The commercial lifecycle of LCD TVs is expected to last at least five more years, ensuring continued demand in the market.
The closures of LCD plants by major South Korean companies have led to supply chain disruptions, particularly in the 40-inch TV segment. This situation presents a window of opportunity for Chinese panel makers. As global demand for LCDs remains strong, Chinese manufacturers can capitalize on this shift by expanding their partnerships and increasing their market presence.
Currently, BOE and other Chinese panel producers are focusing on 8.5-generation lines for 55-inch TVs, while also developing smaller OLED panels. Although only a few Chinese companies operate 4th- to 6th-generation lines, they possess significant production capacity advantages. This positions them well to take advantage of the evolving market dynamics.
In conclusion, while the Korean factory shift toward OLED is creating new opportunities for Chinese manufacturers, LCD technology is not disappearing anytime soon. OLED may not dominate the market immediately, but the next 5 to 10 years will likely bring dramatic changes to the TV industry. The transition is ongoing, and both technologies will coexist for a while longer.
brightness
LCD is a substance between solid and liquid. It can't emit light by itself, so it needs additional light source. Therefore, the number of lamps is related to the brightness of the Liquid Crystal Display. The earliest liquid crystal displays had only two upper and lower tubes, the lowest of the popular type was four lamps, and the high-end one was six lamps. The four-lamp design is divided into three types of placement: one is that there is a lamp on each of the four sides, but the disadvantage is that there will be dark shadows in the middle. The solution is to arrange the four lamps from top to bottom. The last one is the "U"-shaped placement form, which is actually two lamp tubes produced by two lamps in disguise. The six-lamp design actually uses three lamps. The manufacturer bends all three lamps into a "U" shape, and then places them in parallel to achieve the effect of six lamps.
Tip: Brightness is also a more important indicator. The brighter the LCD, the brighter the LCD, it will stand out from a row of LCD walls. The highlight technology we often see in CRT (ViewSonic is called highlight, Philips is called display Bright, BenQ is called Rui Cai) is to increase the current of the shadow mask tube to bombard the phosphor to produce a brighter effect. Such a technology is generally traded at the expense of image quality and the life of the display. All use this The products of this kind of technology are all bright in the default state, you always have to press a button to implement, press 3X bright to play the game; press again to turn to 5X bright to watch the video disc, a closer look is blurred, you need to watch The text has to be honestly returned to the normal text mode. This design actually prevents you from frequently highlighting. The principle of LCD display brightness is different from that of CRT. They are realized by the brightness of the backlight tube behind the panel. Therefore, the lamp has to be designed more so that the light will be uniform. In the early days when selling LCDs, it was a great thing to tell others that there were three LCDs. But at that time, Chi Mei CRV came up with a six-lamp technology. In fact, the three tubes were bent into a "U" shape. The so-called six; such a six-lamp design, plus the strong luminescence of the lamp itself, the panel is very bright, such a representative work is represented by VA712 in ViewSonic; but all bright panels will have a fatal injury , The screen will leak light, this term is rarely mentioned by ordinary people, the editor personally thinks it is very important, light leakage means that under a completely black screen, the liquid crystal is not black, but whitish and gray. Therefore, a good LCD should not emphasize brightness blindly, but more emphasis on contrast. ViewSonic's VP and VG series are products that do not emphasize brightness but contrast!
