RGB LEDs could be the future of cheap screens
Hisense didn’t bring many TVs to CES 2025, but the journey could be a sign of the future of display technology.
The brand’s 116-inch RGB LED TV is called The UX Trichroma TVusing a new kind of LED lighting system that could shake the market. The system cannot turn each small pixel on or off OLED or Micro Ringhowever, it offers equally impressive contrast, along with incredible brightness, great accuracy and other interesting benefits. The secret behind its brilliance lies in its color.
What is an RGB LED?
Backlighting is everything. Traditional LED TVs use multiple dimming zones (called local dimming) and thousands of increasingly small LEDs to combat light leaks around bright objects on dark backgrounds. nevertheless, The best LED TV It produces some prominent light bleeding (or halo) around the bright image, but with less impressive contrast than radioactive light sources that provide a completely black background like OLED and microrelease, each pixel is its own backlight.
Unlike traditional LEDs that produce white or blue light and then run through a color filter, Hisense’s new RGB LED panels produce “pure colors directly to the source” using thousands of light lenses, each containing red, green and blue LEDs. According to Hisense, this is “the widest color gamut ever achieved in a mini-leaf display.” The TV is claimed to produce 97% of the BT.2020 color space, and is available with the vastest display color standard. This technology also offers other performance benefits.
Because RGB panels produce color with a light source, RGB LEDs provide enhanced backlight control and can significantly reduce light bleeding. Hisense calls this technique “RGB local dimming.” It is essentially a light bleeding that LED TV backlight consists of LED zones for better contrast.
In theory, and in the short time spent on CES’ TriChroma TV, Hisense’s RGB Tech offers a deeper black level and better contrast than current LED TVs, giving OLEDs and microrings for money.
RGB vs OLED: 2025 Brightness War
Currently, it is difficult to beat OLED TVs for pure photo performances. Perfect black level blend of OLED, fine contrast, excellent off-axis views, and vast color power The best TV You can buy it. However, OLED has its limitations as to all its benefits. In other words, it is a brightness level that cannot match the most powerful LED TVs.
Considering that the best OLED TVs are already very bright in a vacuum, that might sound dismissive. Flagships like Panasonic’s Z95A (9/10 Wired recommends),, LG’s G4and Samsung’s S95D (8/10 Wired recommends) It’s surprisingly close to the peak glow of 2,000 nits, surpassing the brightest LED TVs for years. The 2025 upgrade could potentially push the latest models past that 2,000 NIT milestone. In fact, the latest panels on Samsung and LG displays claim to be as bright as 4,000 nits with very small windows (though this seems unlikely to translate in real content).
