After I wrote the article, I saw some reports of researchers in Korea working on a Smellivision product. Now HP and Intel are doing likewise but for the digital signage market. Actually, as with other technologies, having a revenue stream behind it might mean that this technology as well gets pioneered in digital signage before finding its way into consumer TV. 4K makes more sense for signage than as a consumer product. No doubt other technologies will follow this path as well.

Smellivision

Glass is Hard Pt III
The first story was told to me and may be apocryphal, the second, I actually witnessed and was a participant in reaching resolution. They were both essentially the same problem. In the first story, it can be hard to appreciate, but commonly parts per billion of some element or another, can have a large effect in stabilizing or processing the glass. Much of glass development is taken up not with developing new glass chemistries but in determining how a glass will react with the impurities it picks up from the furnace. Parts per billion, below the resolution limit of most x-ray machines commonly used for measuring glass chemistry, can have a determining effect on the glass suitability for a particular application. In the second story, one of the recouperators, the part of a glass furnace that captures the heat and sends it back to the furnace, had collapsed and the furnace was being fired with just one recouperator. Although the glass chemistry as was closely monitored before and after the collapse, the glass chemistry measurements usually do not include one of the most important elements, Oxygen. When the recouperator collapsed the melter changed the way he fired the furnace with changed the oxidation state of the glass. The glass chemistry before and after the change was the same but no one was looking at the oxygen.
Fusion glass, used as LCD substrates, is made in platinum lined furnaces to minimize an impact refractory contamination can have. However, raw materials can still have a huge impact. For most "dirt is dirt and sand is sand" however for glass and ceramic making, many times, even when the mining location is changed within the same mine, it means requalifying the process.
LCD v. OLED TV
The fact that the public has gotten used to the idea of a flat panel does not make it easier for OLED technology, it makes it harder in that their is already a product there that is very cheap and its performance is more than fine. Even though OLED visual performance will be better, no one is unhappy with current LCD performance.
What will make OLED technology and what will eventually make an OLED TV commonplace will not be the immediate application of the technology to TV but an application not currently served by LCD; most probably a new product or new form factor that takes advantage of OLED's ability to be made as a flexible or fracture resistant display.... Dick Tracy's watch or some sort of wearable device. Once volume is generated form this new application, OLED can come down in price and be a TV.

4K & Osborne Effect
Normally, I would not be one to criticize the industry regarding anything done to increase profitability in what is largely a profitless business. However, sometimes the things that are done to increase ASPs actually discourage sales. In the early 1990's TV set sales were depressed by talk of HDTV. The discussion in the press about the new standard lead people to believe that HDTV was just around the corner and many postponed buying a TV set thinking that they should wait and get an HDTV. Talk of a new standard frequently discourages sales of current models. This is known as Osborn effect for Adam Osborne driving his own company out of business talking about the next model Osborne Computer, that wasn't ready, and consequently not being able to sell the current one. I believe that 3D had a similarly chilling effect. And now comes 4K.
As I said in a previous post, 4K will be a great boon the digital signage. No doubt it will garner some consumer sales as well. However the net effect on total consumer sales dollars will be minimal if it is positive at all. Currently, widespread realease of 5G smartphones is not expected until 2020. However, whith smartphone prices climbing into the $1000 range, sales of 4G smartphones during 2019 may be impacted by consumers postponing purchases to get the new 5G technology.
