ADS (Advanced Super Dimension Switch) is BOE’s own version of an IPS-type LCD panel. On a TV it looks and behaves like IPS: wide viewing angles, good color and fairly gray blacks. The brightness and contrast gains that manufacturers advertise depend mostly on the backlight and build quality, so ADS is a variation of IPS, not a new class of display.
What is an ADS display?
ADS stands for Advanced Super Dimension Switch. In older materials, this technology is referred to as ADSDS, but in television marketing, it is almost always abbreviated to ADS. From a technical standpoint, ADS is a version of FFS (Fringe Field Switching) technology developed by BOE, and FFS itself is a variant of IPS. FFS technology was developed by Hyundai’s panel manufacturing division in the 1990s.
This is why the term “IPS ADS” is often found in technical specifications. It is not a competitor to IPS technology, but rather one display manufacturer’s interpretation of that technology.
How ADS Differs from Standard IPS Technology
Manufacturers highlight three main advantages of ADS technology: greater panel rigidity, higher brightness, and better contrast. Let’s examine how valid these claims are.
Rigidity
ADS panels do appear to be more rigid and flex less under light pressure. However, this advantage is of little practical importance for TVs, since users rarely touch the screen. It becomes more relevant when ADS panels are used in touchscreen displays, which are constructed somewhat differently and typically include a touchscreen layer and protective glass.
To reduce production costs, manufacturers have also introduced inexpensive panels that can develop light leaks when installed in a TV if the mounting brackets are overtightened, causing the panel to bend. ADS panels may perform better in this regard, but I haven’t seen any comparative tests confirming this advantage.
Brightness
In TVs, brightness is determined primarily by the backlight, regardless of the panel technology. BOE does describe ADS as a technology with a high light transmittance ratio, meaning that more light passes through each pixel. However, claims of a significant increase in brightness should be treated as marketing claims until they are confirmed by laboratory testing.
Contrast Ratio
IPS-type panels typically achieve a native contrast ratio of 1,000:1 to 1,500:1, while VA panels can reach around 3,000:1. ADS technology belongs to the IPS family and generally shares its contrast limitations.
BOE has demonstrated prototype panels with a contrast ratio of up to 3,000:1 at 4K resolution. However, you shouldn’t expect to see these specifications in mass-produced TVs. Although manufacturing such a panel is technically possible, its production cost would make it difficult to compete in the market.
What is ADS Pro?
ADS Pro is BOE’s upgraded version of ADS. BOE lists lower power consumption, touch integration without image distortion, higher resolution and refresh rates, and a wider color gamut as its gains. Treat these as manufacturer claims until a specific TV is tested.
Real example: a BOE ADS panel datasheet
BOE’s own technical specifications for the 55-inch 4K ADS module list a typical contrast ratio of 1,200:1, which is within the range typical for IPS-type panels.

ADS vs IPS vs VA
ADS and IPS trade contrast for wide viewing angles, and VA does the opposite. Figures are typical values, not guarantees for any single model.
| Criterion | ADS (BOE’s IPS-type) | VA |
|---|---|---|
| Viewing angles | Wide, comparable to IPS | Specified up to 178°, but color and gamma shift off-center |
| Native contrast (typical) | Same range as IPS in most retail TVs; BOE has shown research panels at 3,000:1 | About 3,000:1 (2,500:1 to 4,000:1 across models) |
| Blacks in a dark room | Grayish; strong local dimming helps | Deeper |
| Dark-scene weak spot | Expect the same as other IPS-type panels | Black smearing behind fast objects, from slower dark transitions |
| Color accuracy | Comparable to IPS | Good, but less uniform across the screen |
| Typical TV brands | Samsung QN85A (2021); BOE leads ADS panel shipments | Samsung mostly uses VA |
| Best for | Same as IPS | Movies in a dark room |
How to Choose Between IPS and VA
The choice between IPS and VA panels depends on your viewing conditions and priorities. If multiple people watch the TV from different angles, IPS panels are generally the better choice, as they maintain more consistent colors and color gamut when viewed from the side. IPS panels usually reproduce a grayish black, while VA panels deliver a deeper black.
Ultimately, the specific TV model matters more than just the panel type. Motion handling, backlight performance, local dimming, and overall picture quality vary between models, even if they use the same panel technology.
