  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Is there a preferable technology for viewing and coloring our 4k+ footage?

Are LEDs old tech compared to OLED? Are there any advantages to IPS over OLED?

Is it just about Pros and Cons or is one type becoming the new king?

A few internet searches turned up the basics. With this thread I'd like to go more in depth with user feedback and experience from those in the trenches.

Thanks for you input.
 
OLED

OLED

I think the safe assumption in life is the more expensive, The better the quality. It's LED or IPS vs OLED. The later provides better blacks, viewing angle, response times. The others are a bit more of compromise and less expensive. The LED IPS generally get qued into the discussion, because of the price point.

The OLED performs better in less than ideal viewing or grading environments. The studio uses the Sony panel in the grade suite, barebones but not unhappy with it. Waiting to drop coin on the LG 65". Short of having a projector, I find 4k visually performs better in an immersive viewing environment. Basically bigger the better. Sick of watching 4k on small panels
 
Don't forget Quantum Dot as a buzz word. And not all OLEDs are in fact true OLEDs. There is an LG using white OLED as a backlight only. That particular display has great black level but really poor color accuracy and even a 33x33x33 3D LUT can't correct it due to its poor linearity.

Each technology has its pro's and con's. Sometimes you need to find the display that bothers you the least.

The new Sony 4k OLED (BVM) is a thing of beauty.
 
Here's some interesting feedback in regards to this research.

LED and IPS are parts of the same screen technology. Which is LCD.

LED is a type of backlight, which was previously CCFL and IPS is a type of liquid crystal matrix.

True LED emissive screen is what you may see on buildings and in sport events.
 
CCFL? That sure looks a lot like the "CFL" acronym for my Compact Florescent Lights, which I got rid of because they contain mercury.

Do LED, IPS or OLED screens contain mercury or any other poison?

But not all local dimming techniques are implemented the same. And it does seem to be a bit of a hack to overexpose certain areas to give a perceived increase in contrast ratio. I still prefer the OLED and the technology is close to a CRT in terms of pixel behavior. For now the the LCD does have the upper hand in contrast ratio, but I think the OLED is the more promising panel technology for evaluating color.

LED and IPS are LCD screens. In this example LED is backlight under the IPS pixel matrix LCD.

"LED monitor" (such as computer display or TV) is an LCD screen with LED backlight instead of prior CCFL backlight technology, when it was just called "LCD" but now it is added LED for marketing purposes. You can have LED IPS or LED VA/MVA/SPVA or LED TN matrix LCDs, but only IPS pixel matrix is stressed in marketing.

This article is older but useful for LCD screen distinction.
What is missing is the fact that IPS in general has lower contrast than VA tech.

Mercury was in CCFL back lit screens.
LED backlit LCDs and OLEDs are mercury free.
 
Thanks Hrvoje,

There was a study done with people who worked under CFL conditions. Something about those lights can cause headaches. There are enough "headaches" in content creation alone. I can spend over 14 hours in a single day looking at my screen.

I never had a problem with the CFLs in my house until I learned of the health hazard if they break. It's not something I want to support so it's good to know a purchase of a OLED is a step away from toxic hard metals.

Has anyone experienced oled burn in? I returned a 7" oled on set monitor because I wanted to use its extensive scopes in my edit system as well as on set and the. Read that keeping graphics on screen could cause burn it.
 
Are they any consumer RBG-OLED panels being produced or soon to be produced by the major players?

None that I am aware of. There aren't even any RBG LED panels in mass-production any more. Everything has shifted to other designs.
