How can a curved screen improve off-axis?
Click to expand...

But, it would also not be the first time that manufacturers assigned value to some spec based on the idea that it qualitatively improved a viewing experience in some way, only for consumers to find the end result is underwhelming and, more importantly, not worth paying for. Potentially over aggressive image distortion aside, is there a case for curved TV? Yes. Is it necessary, right for every setup, the way forward, or the new standard? No.

The curve is to put the focal point of your eyes/screen at the same distance to anywhere on the screen.

The glare on many screen placements in room is a problem all but solved this way.

The features on top models of Samsung UHD are amazing..... like top computers..... face recognition for individuals' favorite selected channels. pointing to screen functions -- no hand held remote control... WiFi, Internet brousing. The list of technical wizardry is impressive in a "TV".... I dont use much of them but it IS cool stuff. But mostly it is for the UHD.

How do you expect to get any sort of significant radiation from two electrodes spaced apart by the thin dielectric that separates them? Radiation is a function of loop area. With a microscopically thin dielectric film, how do you expect to get any sort of significant loop area?

If you are serious this time......

It's always in the details. Often it is the theory and assumptions vs applied practice:
I am also thinking of the PS electrolytic caps used in PA's where the currents can reach the tens of amperes. These caps are not as tightly wound and spacing is greater (and loose) than say a polyprop film and foil of much smaller value/size. Never-the-less, there are fringe fields at ends or edge. You can also use a pick-up loop around them to measure this. More sophisticated field probes are also useful when accuracy is needed.

It is. At the same time, on leaded parts they come out about those locations . . .
Maybe some.... many I have physically taken apart do not... they have a tab at start and stop of winding..... large PS electro... leaded types. Cheap and reliable method.
I did note that the SMD x-ray'ed had a max current rating of 70mA and with compactness fringing affects should be relatively smaller.

Now I am curious about this location at a percentage of the winding affecting the Z curve. Broaden the min Z vs freq, perhaps?

Dont want to be accused of hijacking this... back to the ByBee issue.

THanks, -RNM

Then let's see your measurements.

Anyone curious to learn the extent of fields from parts, wires, cable, cords etc might invest in a simple device such as this --- Trifield Gaussmeter 100XE EMF Electromagnetic Field Radio Magnetic Wave Meter | eBay

It is useful in learning more about layouts and isolation and shielding effectiveness etc Or even large cap and transformer fields.

I have one of these in my test equipment arsenal [as well as field probes, CT et al]

I am in my condo in Bangkok and do not have access to any archived files nor test equipment (other than some I shipped over here for specific project).

No, the new ultra thin flat screens. Without a curve, they would need to make them fatter for structural reasons. The idea that the curve is better for watching is the marketing department kicking in. The theory behind it is shaky and most professional reviewers are not that fond of it.

Don't attach any value to this post, it is all conjecture from my side, but plausible none the less.

I wont...... I have never seen any marketing about the curve yet... The thickness is about on par with many other flat screenss..... this one measures 2cm - 3.5cm thick. Not a reason for curving.

In the last 2-4 weeks I had both eye lens replaced in my eye balls. Laser surgery... SOTA. Corrected vision now is 20/25 in both eyes and will improve as they heal. The UHD never looked better and I have top plasma HD (B&W and color calibrated) to compare it to.

Carry on........... with ByBee

There are non because it is only used in audio designs, I don't know anyone who would use it in normal electronics, there is no data so you don't know what it is going to do in the circuit (though replies tend to be more colourful). It is mainly only in the esoteric world of audio where magical components are used....

No healthcare applications, such as ultrasound, for Quantum Purifiers ? Seems strange. It's a large growing market.

high cost, single sourced component, with no data sheet, this would be a big hit* in any product design review.

*in a "functional" organization there would be some serious fraud investigation and possible terminations for any PE that allows this to pass muster. If he isn't fired for diverting funds he will be for gross incompetence.
