The LG B1, being an OLED TV, offers superior contrast, perfect blacks, and excellent viewing angles, making it ideal for movie enthusiasts and those with wider seating arrangements. It's particularly great for gaming due to its responsive screen and low input lag. However, OLED screens can suffer from brightness limitations in very bright rooms, and they carry a premium price tag. In comparison, the TCL R646, which uses LCD technology with mini-LED backlighting, provides a brighter screen, which is beneficial if you're placing the TV in a sunny room. Its picture quality overall is commendable but falls short of the LG B1, especially in terms of contrast and viewing angles. Sports content might not look as good on the TCL due to its lower motion processing capabilities. It's generally less expensive, making it a budget-friendlier option. If you prioritize top-tier image quality, especially for movies and gaming in darker environments, and don't mind paying more, go for the LG B1. On the other hand, if you prefer a brighter screen for well-lit rooms and want to save some money, the TCL R646 might suit you better. Give Feedback

The LG B1 (OLED) is very good for movies & TV, while the TCL R646 (LCD) is good.
The LG B1 OLED excels in watching movies and cinematic TV due to its perfect contrast, superb black uniformity, and 100% efficiency in local dimming, which allows for very deep blacks and a high level of detail in dark scenes. The TCL R646 LCD, while delivering good performance with its contrast and local dimming, falls slightly behind in these areas, and its lower black uniformity performance and narrower viewing angle could reduce the richness of the viewing experience compared to the LG B1.

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.
