Huawei's Honghu Chip to Change the Game for RGB MiniLED TVs
This new processor from the Chinese brand has set a new benchmark for this type of TV.
You may not have thought of Huawei as a TV brand, but in China, it's one of the leading brands when it comes to buying new smart TVs. Anyway, today we're talking about a new processor designed by Huawei for RGB Mini LED TVs.
This processor looks set to change everything. For now, it's exclusive to Huawei and its Huawei TVs, but there are rumors that it may be licensed to other brands in China.
The real bottleneck for RGB MiniLED technology wasn't the manufacturing of the diodes themselves or the number of sensing zones, but the electronic device that controlled those countless diodes and sensing zones. The launch of Huawei's new Honghu RGB chip finally shifts the focus back to where it should be: the backlight processor and the ability to manage the TV's new RGB diodes.
The Real Problem with MiniLED RGB TVs: The Technical Challenge of Diode Control
As we know, all MiniLED TVs used blue diodes with color filters to create images, which led to two major problems: poor color reproduction, high power consumption, and low brightness. This was until the advent of RGB models, which offered a tremendous solution to these issues.
However, the RGB model also brought its own set of problems:
-- Each primary color in the RGB matrix operates differently:
-- Red LEDs degrade at a different rate than blue LEDs.
-- Temperature changes the wavelength unevenly.
-- Synchronizing thousands of light sources requires microsecond-level control.
If the electronic device is not extremely precise, color crosstalk (color interference), blooming (where green or pink tones become overly sensitive), and color distortion that ruins the image can occur. To prevent this, manufacturers had to fill control boards with dedicated physical components, which significantly increased production costs and limited this technology to ultra-high-end TVs. The solution lay in finding a middle ground that addressed the problem without excessively inflating manufacturing costs. This is where Huawei came in.
Huawei Solves MiniLED RGB TV Problems with 'Hardware Algorithm'
It is at this point that Huawei and its new Honghu RGB chip enter the picture. This Chinese brand has not only gone beyond simply incorporating better diodes, but has also designed a processor with computational capabilities capable of acting as a dedicated 'digital colorist' for each LED group.
This new processor analyzes video signals in real time and independently adjusts the brightness and hue of each diode. But the true achievement lies in its architecture. The chip directly integrates multi-LED cooperative calibration, instant color correction, and dynamic mapping into its algorithms. By moving tasks to the chip's artificial intelligence, it has drastically reduced BOM costs by eliminating a large amount of physical components from the control board.
The processor demonstrates exceptional performance, proving capable of controlling RGB MiniLED panels and managing thousands of LED zones integrated into the matrix. This will likely force other manufacturers to pay more attention to processors in the case of MiniLED RGB TVs.
Simply increasing the dimming zones without the underlying electronics to support them is meaningless. The new technological war for MiniLED will be fought on the intelligence of silicon, and the Honghu RGB chip has fired the first shot.
