1. Does the TCL 55-inch 55P638 Google TV use an LED or QLED display panel?
Answer: The TCL 55P638 doesn't use an LED or QLED display panel; it utilizes an LCD panel. This means it doesn't use LED backlighting or utilize quantum dot light like QLED but rather uses fluorescent backlighting.

With this display panel, the TCL 55P638 TV is thicker compared to conventional LED TVs and also consumes more power. Currently, it's the cheapest TV display panel on the market. However, the advantage of this type of display panel is its affordability, decent durability, and ease of repair, hence it's still being applied by many manufacturers in their budget TV models.
On the other hand, the TCL 55P638 is equipped with a 4K resolution screen and HDR10 technology, along with the new AIPQ 2.0 image processor, bringing sharp and vivid image display capabilities. Alongside, this 55-inch TV also features Micro Dimming technology to more accurately control the backlight, coupled with various viewing modes to optimize image quality depending on the content displayed on the screen.
Meets the needs of mainstream users without being overly demanding on image quality.

Quick answer: Yes
Specifically, the TCL 55-inch TCL 55P638 TV integrates a 60Hz refresh rate, which is the average refresh rate in the current market, even for higher-end TV models. Additionally, most TV programs, movies, or online content only support this refresh rate.
Therefore, when watching action movies or football matches, the images of this 4K TCL TV still maintain an impressive smoothness. However, for fast-paced scenes like football matches or racing, keen viewers may still notice some blurring.
