The students from Lama did not visit the show factory this year, including the production of CRT kinescopes. As for Sharp's Kameyama and Kyodo, LGD's Paju, companies in mainland China such as TCL's Huaxing Optoelectronics, several low-generation lines are also expected to be passed. In reality, the display industry is highly technical. As a codeword person, I can only understand some concepts or the pros and cons. However, with the release of the iPhone X and the sales of OLED TVs during National Day and Double 11, there has been a noticeable increase in interest in OLED technology. Recently, I've received many questions, so I'm putting together a QA post, trying to keep things objective and straightforward. (All questions are original.)

**1. Is an OLED TV really better than other display technologies?**
The term "better" is always relative. It's hard to give a simple yes or no answer. However, OLED is a revolutionary technology in the television industry, offering unique advantages in certain aspects. From image quality, OLED provides deep black levels, nearly infinite contrast, wide viewing angles, and fast response times—features that make it excellent for TV. Additionally, since OLED is flexible, it allows for curved and even unconventional TV designs. Due to its self-illumination structure, OLED TVs are much thinner than LCDs, enabling innovations like "wallpaper TVs" and even screen-sound technology (CSO). In short, OLED has opened up new possibilities for the TV industry, and there's still a lot of potential for future development.
Besides OLED, the mainstream technology is LCD. Most quantum dot TVs are just improvements on LCDs. While quantum dots offer better stability and color purity, they are mainly used to enhance color gamut and accuracy. Their lifespan is longer, but the fundamental nature of LCDs remains unchanged.
In general, OLED is a completely different and advanced display technology compared to LCD. The current challenge is high cost and limited output, which prevents it from becoming mainstream. However, its unique features have already attracted a growing number of consumers, and OLED is increasingly found in high-end products.

**2. Will the sale of the iPhone X really drive the OLED TV market? Is there a difference between mobile phone OLED and TV OLED?**
It's a great question. While the iPhone may not directly impact the TV market, it definitely increases public attention to OLED technology. Mobile phone OLED and TV OLED are indeed different.
Apple doesn't use OLED panels in its phones; instead, they use AMOLED (Active Matrix OLED), which is a classification of OLED technology. AMOLED isn't necessarily more advanced than TV OLED, but it refers to the type of driver used. Both smartphones and OLED TVs today use AMOLED screens. So when you hear "AMOLED," it's just a technical term—not a sign of superiority.
However, even though both are AMOLED, the implementation differs significantly between small-sized mobile panels and large-sized TV panels. Samsung dominates the small panel market using RGB subpixels, while TVs often use WRGB (white OLED) due to better yield, cost, and brightness. This leads to differences in resolution and visual performance.
Despite these differences, both technologies face challenges. OLED is still relatively new, and there's room for improvement. But the industry is constantly evolving, and we can expect better solutions in the future.

**3. Apple said OLED screen burn-in is normal. Does this apply to OLED TVs? Is OLED immature?**
Burn-in was first seen on PDP (Plasma Display Panel) TVs and is a known issue with self-illuminating technologies. It's not unusual, but it's something manufacturers are actively working to solve.
LG Display, one of the main OLED TV panel suppliers, has developed techniques to reduce burn-in, such as timing refresh and brightness monitoring. Some TVs now come with built-in tools to prevent long-term image retention. While OLED is still a young technology, it's continuously improving, and problems like burn-in are being addressed.

**4. Why are OLED TVs so expensive?**
Currently, OLED TV panel output is around 1.7 million units per year, far below the 230 million global LCD TVs. In the early stages of any new technology, prices tend to be high. The manufacturing scale is small, and key materials and equipment are controlled by a few companies, making OLED TVs costly.
However, as demand grows and production scales up, costs will decrease. LGD plans to expand production in Guangzhou and Paju, aiming for 6.5 million units by 2020. Once mass production is achieved, OLED TVs could become more affordable. In fact, OLED technology is simpler and uses fewer materials than LCD, so cost should eventually be lower.
So, if you're waiting for OLED TVs to get cheaper, it might be worth it. But remember, new tech usually comes at a premium. Wait too long, and you might miss out on the next big thing—like printed QLED or other emerging technologies.

**5. Is LG the only company producing OLED TV panels? What's the global landscape?**
If the question is whether LG is the only one, the answer is yes—at least for now. LG Display is the only company mass-producing large OLED TV panels. Most OLED TVs sold in China are based on LGD panels. However, other companies like BOE are also working on their own OLED technologies.
Globally, LG is leading, but the market is expanding. In the next few years, more brands may enter the OLED TV space, including those that previously didn’t focus on this technology.
