We could drive our walls up to 1000-1200 nits, but we choose not to in the TWA family because of those reasons. all LED walls can go to ZERO light output for black, so they all have "infinite" contrast, technically.
Relative to other products, there are pros and cons. The Sony is not available in .9 pitch, so 4k walls would not be possible in most residential settings. Also, the Sony has much more depth, heat, and noise.... which additionally limits the places you can put it. Leyard has front servicable .9 DVLED with an installed depth of <4". (DirectLight) For the well-heeled, it can replace a flat panel or projection system in most residential settings.
TWA is made up of 4"deep cabinets, so that, plus your mounts, could mean installed depths under 12".
The Sony has a textured glossy surface, which doesn't come without its tradeoffs. It looks good, for sure, but as a product, it comes with some additional obstacles, relative to Leyard, that the integrator must consider.
As a company, we dont see what Sony is doing as having much of an impact on our core markets. The Sony isnt even in the conversation with most of our clients, because it doest fit their application or budget. The Leyard .9 4k wall is $400,000 but the Sony is more, is lower resolution relative to surface area, and doesnt fit in the same spaces.
If your only data point is peak brightness, then maybe the Leyard isnt for you. Other than that it is subjective to call the Sony "competition" with the Leyard wall.
Ah, excellent. Thank you for reaching out. It's fantastic to be conversing with those actually behind this Leyard product. This demonstrates just how useful these forums can be.
Please take what I have said as constructive criticism and not being dismissive. My company specializes in high-end home audiovisual and the sort of comments and observations that I have been saying are precisely the sort of discussion we will be having with some of our high-end clients and customers, who will wish to know for example whether the product performs as well as their TV and/or other similar products on the market.
There is definitely a market for seamless modular 4K HDR video walls with respect to the high-end domestic home theater/cinema market. However, these products are going to need to be able to hold their own against stiff competition from other video display products. If you are confident that your product ticks all the right boxes as far as what consumers are looking for and will hold its own as compared with the competition then we'd absolutely love to learn more about your product.
So, thank you for your further information and clarification with respect to the video performance specifications of your product.
Firstly, I must disagree with your statement that "peak brightness and contrast is all a bit of a marketing game"
given both of these parameters are all-important with respect to video performance. Other important aspects include: Minimum 100% of DCI P3 Colorspace; Support for both 10-bit and 12-bit Colour Depth; Support for 4:2:2 and 4:4:4 chroma subsampling; good response times and low input lag; full HDR compatibility and support with respect to all of HDR10, Dolby Vision, and HDR10+; support for High Frame Rates (HFR) including 60fps and 120fps; and support for 3D etc. etc. It is these criteria which are the demand of consumers and pre-existing consumer video displays offer these. Some consumer video displays don't yet support Dolby Vision or HDR10+ but it's heading that way and it's important for any high-end video display product, as yours clearly is, to support everything that's applicable to the high-end of video, so that means ideally your product should be supporting all of these.
With respect to your current marketing information (such as your product specification/technical information sheet here: http://www.planar.com/products/led-v...d%20TWA0.9.pdf
and your product brochure here http://www.planar.com/media/436602/l...re_07-2017.pdf
) it would appear that your product has been developed for the commercial/professional industry and you are exploring the possibility and/or seeking to sell it into the domestic home theater industry. As such, given the further information and clarification that you've just posted, my comment is that you should consider producing new marketing information, such as a new marketing brochure accordingly, because at the present time your as far as the domestic home theater industry is concerned your product specification sheet and brochure leave a lot to be desired, don't do your product the justice it deserves, and necessitates a further education step to attain the level of information that it should be communicating in the first place. For instance, your documenation lists the following:
- Brightness Max (cd / sq m) = 600 nits
- Contrast Ratio = > 6,000:1
- Color Gamut = 100% NTSC
- Video Input Resolution Maximum = 1920 x 1080 @ 60 Hz
- Frame Rate = 50, 60 Hz
- Color Processing = 10 bit
Where you are either talking in terms that are different as those used to describe consumer video display products and/or the figures listed are not apples-with-apples as compared with those typically specified with consumer video display products. Furthermore, there's numerous instances of vital information that AV professionals and customers alike would wish to know that are missing.
First of all, it indicates a peak luminosity of 600 nits where in the language that home theater enthusiasts and professionals first impressions will be that that does not impress. You should note that with respect to consumer TVs the industry standard video performance specification refers to peak luminance of 10% window of white 235, where for example the new 2018 Philips OLED has a peak luminance of 900 nits; and the 100" Sony Z9D/ZD9 is 2,500 nits. But you state 600 nits, without mentioning that this applies to full field white 235 and not the typical definition within the consumer video industry that describes peak luminance of 10% window of white 235. So a lot of folks are going to jump to the wrong conclusion. This is just one aspect of many where your current marketing information won't be doing your product any favours.
Furthermore, you use the term 'Brightness' to mean Luminance, when in fact as far as both professional video calibration and consumer video displays are concerned Brightness relates to Black Level, and not Luminance. Again, confusing.
Contrast Ratio is listed as being only 6,000:1 but you are claiming in reality it is much higher than this? If this is the case, then why say it's only 6,000:1? Please note that claims of 'Infinite' contrast ratios aren't received well here... unless they are actually genuine and not simply only applicable to a full field black 16 image. Therefore, are you saying that whenever there is a full fade to black, namely a full field black 16 image, you simply turn off the light source and hence the contrast is 'Infinite'? Because that's completely meaningless. What's important is what is the contrast ratio with actual video, not when the display is turned off or full fade-to-black only. Therefore, what's important here is what is the luminance level of the full field with a single pixel as white 235 and the rest black 16? Is the luminance the same as a full field black 16 image plus the luminance of the singular white pixel? Or is it higher than this? If it's higher then that's NOT true 'Infinite' contrast but the fake/fudged sort which doesn't wash here. So, I ask you, what is the contrast ratio with a single white pixel? Is this 6,000:1 or is it greater? Ultimately what's most important here is perceived Black Levels, where native contrast is only one aspect that influences this. However, it's an important measurement nonetheless, although there are other factors that influence perceived Black Levels which are also important as well.
Next let's move on to Color Gamut. In your marketing information you state "100% NTSC" when the consumer video display specifications are listed as percentage of the respective colorspaces, previously Rec.709, now DCI-P3 and/or BT.2020. Where "100% NTSC" is meaningless to most people. Ideally for a high-end consumer display your product needs to be delivering at least 100% DCI-P3, but preferably towards 100% of BT.2020. Sony's CLEDIS reports the latter. Either way, the consumer video display industry standard is now DCI-P3 colorspace, so your product should be talking in terms of that and not NTSC. As it stands it's another example of where your current marketing information is both unhelpful and confusing.
Onto image resolution, very unhelpfully and again confusingly your marketing information states: "Video Input Resolution Maximum = 1920 x 1080 @ 60 Hz"
; where many folks will conclude that this is an HD only display and doesn't support 4K. However, you and I know that this is a modular product with fixed pixel resolution so you can quite easily create a 4K resolution screen simply by combining the corresponding number of video modules together. So really you'd be best to change this because currently it's both misleading and confusing. You want to be pitching this product as a 4K display, not "1920 x 1080" = HD.
Frame Rate lists 50 and 60Hz only, which begs the question does it support 24 and 25? And Color Processing states 10-bit, when the industry standard necessitates support of up to and including 12-bit.
Consequently, for you to be truly successful with respect to selling this product into the consumer home theater/cinema industry you need to bring both your marketing information including terminology and specification details, as well as the actual performance specifications of the product itself, in line according to what are the industry standards as of right now. The aforementioned are merely some examples. There are others (e.g. does it support HDMI 2.0b? HDCP 2.2? What HDR formats does it support? Dolby Vision? Etc.) but at least this points you in the right direction.
I think that your product has great potential. In its present form and with respect to the current marketing information there are issues, regarding which I have already commented. However, I think that if you take the necessary steps from here to ensure that it ticks all the right boxes performance-wise and compliance-wise, as well producing some proper marketing information that's optimized for the consumer home theater industry, then your product has the potential to be successful, regarding which we wish you the very best.
As a company, with this further information and clarification you have rekindled our interest, so I will PM you our details as we'd like to learn more.
