Whose matrix in Xiaomi 4S TVs: a complete analysis

When choosing a modern Smart TV, many users pay attention not only to the screen diagonal, but also to the image quality, which depends on the type of matrix used. Xiaomi brand has gained popularity due to its excellent price-performance ratio, but the company’s range of models, including the TV 4S series, often raises questions about the origin of components. Electronics manufacturers rarely disclose the exact suppliers of panels for each batch, which creates a lot of speculation.

The question of whose matrixes are installed in Xiaomi 4S TVs worries buyers looking for a guarantee of high contrast and color reproduction. In this article, we will discuss the technical side of the issue in detail, based on the results of hardware tests and teardown analysis of popular models. Understanding which display you buy will help to avoid disappointment and make an informed choice.

It should be noted that Xiaomi, like many other major players in the market, uses a multisourcing strategy, which means that in similar-looking cases, panels from different manufacturers can be found depending on the date of release and the region of supply. So the answer to the question of the matrix supplier cannot be unambiguous for all devices at once, but we will highlight the main patterns.

Panel procurement strategy for Xiaomi TV

The Chinese tech giant does not own its own LCD panel plants, relying on contracts with the world’s leading manufacturers, and its main TV partners include BOE, CSOT (TCL), Innolux, and, in smaller volumes, Samsung Display and LG Display. The choice of a specific supplier for the 4S series depends on the availability of components at the time of assembly of a particular batch.

The most common supplier for budget and mid-budget lines, which includes the 4S series, is BOE Technology. These arrays are known for their accessibility and acceptable quality for the mass market. However, in some diagonals, especially in the popular 43 and 50 inch models, CSOT panels are often found, which are characterized by good brightness and stability of black.

Sometimes users confuse the software shell or certification logos with the actual screen manufacturer. It is important to understand that the presence of HDR technology or Dolby Vision support does not guarantee that the matrix is manufactured by Dolby or Samsung.

The main supplier of matrices for the Xiaomi 4S series is BOE, however, depending on the batch, CSOT or Innolux panels can be found.

Analysis of matrices in popular 4S diagonals

By looking at specific models, you can see a clear correlation between the screen size and the likely matrix manufacturer. TV 4S 43 most commonly found VA-production-matrix CSOT (unit TCL). This is confirmed by the tests for the viewing angle and contrast level, characteristic of vertical alignment technologies.

Larger diagonals, such as 50 and 55 inches in the lineup 4S, often equipped with panels from BOE Or Innolux. These matrices tend to have IPS-structure ADS (analogue IPS from BOE), which provides wide viewing angles, but can be inferior in depth to black color compared to VA-The difference in the types of matrices has a significant impact on the perception of the picture when viewed in the dark.

To determine the type of matrix without disassembling the TV, you can use a simple visual test. If you swipe the screen with your finger (iris bending), you have an IPS/ADS panel. If the screen just gets darker or lighter without iridescent effects, this indicates the use of VA technology.

• 📺 43 inches: Mostly VA-matrix CSOT, deep-black.
• 📺 50-55 inches: Frequently encountered IPS/ADS panel BOE Innolux with wide viewing angles.
• 📺 65 inches and above: Panels from different vendors, including AUO and BOE, highly probable VA-layer.

Technical specifications: VA vs IPS

Understanding the Difference Between Technology VA (Vertical Alignment and IPS (In-Plane Switching is critical when evaluating the quality of Xiaomi TV 4S. Most observers agree that for watching movies at home, especially in the dark, VA-The matrix is preferred because of the high native contrast, and the black color on them looks really black, rather than dark gray, as on the other side. IPS.

On the other hand, IPS-The panels that are also common in Xiaomi TVs benefit from color stability when viewed from an angle. If you plan to watch TV with a big company, sitting on the sides of the screen, you can see that the color is stable. IPS It's going to make it more uniform for all viewers, but the brightness and the saturation of the colors. IPS-Matrices may appear lower when viewed directly compared to quality VA-analogue.

It is worth noting that the quality of a particular matrix depends not only on the technology, but also on the class of the panel itself. Even within one manufacturer, there are quality gradations (A, B, C class) that affect the number of broken pixels and the uniformity of the backlight. Xiaomi usually buys high-end panels, but the risk of hitting a device with an imperfect matrix is always there, as with any other brand.

⚠️ Warning: Don't blindly rely on marketing names for technology "4K HDR" describes the resolution and support of the format, but says nothing about the type of matrix (VA or IPS) or.

The impact of the matrix manufacturer on image quality

The matrix manufacturer sets the basic level of display capabilities, but the final image also depends on the video processing processor. Xiaomi 4S TVs use chipsets from Amlogic or MediaTek that zoom in and use noise reduction algorithms. A good BOE matrix can show mediocre results when calibrated poorly, and vice versa.

Color gamut is another parameter often credited to a particular panel manufacturer: Samsung's panels and the panels. CSOT (VA-type) traditionally show a wider color coverage in native mode, which makes the picture more juicy. IPS-panel LG or BOE You may need to adjust the color profiles in the TV menu more carefully to achieve natural shades.

The screen refresh rate is also important. Most Xiaomi 4S models are equipped with 60Hz matrices. Despite marketing tricks about "MEMC 60Hz" or interpolation, the physical refresh rate remains standard, and this should be considered by gamers planning to connect new-generation consoles, for which 120Hz parameters and VRR support are important.

Comparison of matrices in different 4S models

For clarity, we compare the likely characteristics of the matrices in different diagonals of the popular series, based on statistics of repairs and breakdowns of equipment, since the official specifications from the manufacturer often do not exist in the public domain.

As you can see from the table, the lottery with manufacturers is real, but there is a trend: smaller diagonals are more likely to receive a lottery. IPS-These are the medium and large sizes that are VA-And that's logical, because on big screens, the effect of black light on the screen is very much the same. IPS much more visible.

When buying a TV in a store, you can't know the exact serial number of the matrix before opening the package or performing complex tests. However, knowing the trends of supply for a particular diagonal, you can assume with high probability that inside. For example, buying a 43-inch model is likely to get you a better price. VA-screen.

💡

When you receive a TV in a store, turn on a demo video with dark scenes. Pay attention to the corners of the screen: if they are lighter than the center (Clouding effect), this can be a sign of a dark scene. IPS-matrix or poor-quality backlight assembly.

How to check the type of matrix yourself

If you already own a Xiaomi 4S TV and want to know exactly what array is installed in your device, there are software and physical methods of checking. The easiest way is the visual angular test, which is mentioned earlier, it requires no special equipment and gives 90% accuracy in determining the type of matrix (VA or IPS).

More advanced users can use the engineering menu or special applications for Android TV. By installing the AIDA64 or Device Info HW app from the Google Play store, you can get detailed information about the hardware components. However, the name of the matrix manufacturer (for example, "BOE" or "Samsung") in these programs is rarely displayed, more often you can see only the resolution and frequency of the update.

For those who are ready for more complex actions, there is a method through ADB (Android Debug Bridge), connecting to the TV from a computer, you can request system logs, where sometimes the ID of the panel is mentioned, and the command to output information about the display can look like this:

adb shell dumpsys display | grep -i "panel\|display"

The result of the execution of the command may contain code notations that experienced professionals can decipher. For example, certain prefixes in the ID panel may indicate a vendor. However, for the average user, this method can be excessively complex and does not guarantee a single answer without a database of codes.

• 🔍 Visual test: Swipe across the screen. Rainbow divorces — IPS, divorce-free — VA.
• 📱 Applications: Use Device Info HW to obtain technical data on the display.
• 💻 ADB-For advanced users, it allows you to get ID equipment.

⚠️ Attention: Use ADB And logging into the engineering menus can cause you to reset or disrupt your system if you carelessly handle it.

Outcomes and recommendations for selection

To sum up, Xiaomi 4S TVs use matrixes from leading Asian manufacturers, mainly BOE, CSOT and Innolux. Direct shipments from Samsung or LG in this series are extremely rare and are not standard. Image quality primarily depends on the type of matrix (VA or IPS) that is tied to the diagonal, not the brand-supplier.

If you are interested in deep black and you are watching a movie in the dark, focus on models with a diagonal of 43 inches and above, where the probability of meeting a movie is high. VA-If the TV is used as a background in the kitchen or in a brightly lit living room, where the viewing angle is important, then the television is used as a background in the kitchen. IPS-panels in 32-inch or some 50-inch models will be a better choice.

Don’t chase the mythical “brand matrix”, as even the panels of the same manufacturer can differ from batch to batch. it is much more important to check a particular instance in the store for the absence of lights and broken pixels. Xiaomi offers decent build and calibration quality for its price segment, regardless of whose “glass base” is installed inside the case.
