The LG B1 (OLED) offers excellent overall picture quality, performs exceptionally well in dark rooms, and has low input lag, making it great for gaming. It also has wide viewing angles and handles reflections well, but it is not as bright in well-lit rooms. The TCL R648 (LCD) is brighter than the LG B1, making it better suited for bright rooms. It also offers good picture quality but lacks the perfect black levels of OLED, resulting in a slightly lower contrast. It's a strong choice for animated content and comes with great speakers, plus it supports 8k resolution. If you prioritize gaming, movie watching in dark environments, and wider viewing angles, go for the LG B1. If you want a brighter screen for well-lit rooms and better built-in audio, consider the TCL R648. Give Feedback

The LG B1 (OLED) is very good for sports, while the TCL R648 (LCD) is only fair.
The LG B1 OLED has excellent response time, which is essential for watching fast-paced sports to avoid motion blur, and its wide viewing angles ensure a clear image from different positions, ideal for group watching. The TCL R648 LCD, while handling reflections well, doesn't match the LG B1 in terms of motion processing and viewing angles, making it less suited for sports where these factors are very important.

The LG B1 (OLED) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The LG B1 OLED provides better upscaling and showcases more vibrant colors straight out of the box, making it well-suited for watching news and TV programs. In contrast, the TCL R648 LCD shines with higher SDR brightness which could be beneficial in bright rooms, but its out-of-the-box colors are not as vivid as the OLED, and its upscaling is also less impressive.

The TCL R648 (LCD) is very good for bright room, while the LG B1 (OLED) is good.
The LG B1 has good SDR brightness and handles reflections excellently, making it suitable for bright rooms, although its HDR brightness is only fair, possibly limiting HDR content's impact in such environments. The TCL R648, on the other hand, boasts excellent SDR brightness and very good reflection handling, ensuring a clear picture in bright rooms; however, its contrast, color volume, and color gamut are not as impressive as the LG B1's OLED, which may affect picture quality in darker environments.

About LG
LG, a prominent TV brand from Korea, has played a significant role in popularizing OLED TVs. OLED technology is hailed as the future of TV technology. Their TVs employ WebOS, a proprietary smart TV software that not only offers seamless functionality but also includes gaming-specific features, earning praise from players worldwide. Often regarded as the gateway to unparalleled viewing experiences, LG's mid-range OLEDs come highly recommended, making them a worthwhile investment for those willing to stretch their budget for superior quality.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
