OLED screen makes the body slimmer In terms of appearance, the OLED C7P uses the same self-illuminating OLED as the LG's other flagship model W7. Because it does not require a backlight system, OLED TV has always had the advantage of a slim body. This time we experienced the 65-inch LG OLED 65C7P, which is indeed slimmer than the previous LG OLED TV.
However, unlike the W7 that must be used for wall mounting, the LG OLED 65C7P can be used with a stand base. It adopts a trapezoidal alpine base with a very strong design and is made of all-metal materials. It's also fashionable and light and it feels very stable.

Comparison of picture quality: The outstanding performance of the Korean brand image quality can be seen through the actual picture quality of the SLR. The screen performances of the two flagship products of LG and Samsung are very good, especially in the details of the shadows thanks to the innovative technical performance of the screen. The performance is more abundant in place. Compared with the traditional Japanese brands have better details.




Through the system experience of 4 TVs, it can be found that Korean televisions have adopted a self-developed TV UI system, which is a closed system, and the software has some limitations. For Chinese users, the Android system is obviously more intimate. After all, both software and control habits have had a very deep accumulation. The playability of software and the familiarity of consumers have also been enhanced.

As a savvy consumer, of course, is the preferred cost-effective products, of which 16999 yuan Sharp LCD-70TX85A although the screen performance and performance is a bit inferior, but with its price advantage and 70-inch screen will surely attract a lot of Consumer attention.
