The LG C1, which is an OLED TV, typically costs less and is known for great picture quality in dark rooms, excellent gaming performance, and a wider viewing angle, making it suited for movies and immersive gaming experiences. However, its screen might not be as bright as you'd like in well-lit rooms. The TCL R648 is an LCD TV with a higher price and is better in bright rooms owing to its brighter screen. It also has good speakers built in, which might be better for general TV watching and news. However, its overall picture quality, particularly in dark rooms and viewing angles, isn't as impressive as the LG C1. Choose the LG C1 if picture quality and gaming are priorities and you're viewing in dimmer conditions. Consider the TCL R648 if you're more focused on bright room performance and built-in sound quality. Give Feedback

The LG C1 (OLED) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The LG C1 excels in upscaling, producing clearer images for low-resolution content typical in news and talk shows, and its OLED screen delivers perfect contrast and colors that look accurate straight out of the box. On the other hand, the TCL R648 stands out with its bright LCD display, improving visibility in well-lit rooms and showing vibrant colors, though its upscaling quality is inferior to the LG C1, which could result in less clarity for standard-definition content.

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.
