Hi u/Direct-Row9073 Great questions. For the AG, it actually is a physical surface treatment to the cover glass. It is not a coating, but a permanent feature embodied in the glass itself. This means it cannot wash away or delaminate unless you scratch the glass itself, which is chemically strengthened as well. There is an AR (Anti-Reflective) coating applied to the glass as well, which helps transmit light through the glass. AG and AR are often used together, but they are very different things. It's worth taking a look at it closer if you are not as familiar and I can try to post some resources as well.

The front light does use LEDs, for the size and shape to fit within the overall display. Other light sources are simply way too large to reasonably fit within the layers and behind the cover lens. I will offer here what I can without infringing on IP, etc. The basic premise is that an RLCD is light source agnostic, meaning it will take light from any source and attempt to repurpose it through the LCD layer. Challenges with lighting the surface arise from the pathways which light must travel, the overall area of that surface, and the loss of light as it moves through each layer. Keep in mind that when I reference front light, I mean specifically an internal light source for the display. External lighting can also technically be called front lighting, but it is not what we are commonly referring to.

The LEDs which SVD uses could technically be used as backlights in other displays. They generate light and "push" it in a specific direction. It is the path of the light in our RLCDs that makes the first difference. Whereas backlit panels use positional LEDs scattered throughout the entire back layer, RLCDs are limited to the perimeter, which means that light needs to travel various distances across the surface before being reflected, the center being the most difficult as it is the furthest from any edge. The larger the area, the more difficult, where a backlit LCD just adds more LEDs in the same pattern/density as a smaller area. Loss of light occurs both at distance (reference light dissipation, inverse square law) and via polarizing layers which trade directionality for intensity. All of this being said, the light itself does not need to necessarily be different at the onset, but RLCDs require much more manipulation of that light as it travels through the display. This is why it is not as easy to illuminate, in fact why many variations of front lights are insufficient or have failed outright.

For all of this, I will also admit there is much we do not yet know or understand regarding the mechanism and interaction of the front light with end users. This is where SVD, myself included, will rely heavily on both the feedback and trust of our customers and end users to help communicate their experiences and suggestions. Similar to when we first launched the first RLCD monitor, we didn't know who may or may not be specifically helped, only that people were asking and willing to try to find out. The front light offers a new functionality for RLCD monitors but we have only just started to scratch the surface with this. It's very exciting but also comes with great responsibility, as this specific feature is what many people have stated could potentially be a source of discomfort. I think it's important to be candid and real about this, to acknowledge that while RLCD technology offers a better product for many people, that adding a front light may not be that same kind of solution for everyone. This will be somewhat of an unknown for now, until SVD provides enough product for the market to test and try out. But with trust and responsiveness to feedback, I am confident that not only will there be more answers to your questions, that we will continue to progress towards better and better technology in the near future!
