Below is a demonstration of Pyrsms 6K 225" Laser Phosphor Display.
THIS WEBSITE IS NOT ASSOCIATED IN ANY WAY WITH PRYSM. THIS IS THEIR TECHNOLOGY AND THEIR INTELLECTUAL PROPERTY.
Brief - Laser Phosphor Displays are a technology that exist right now, and has since some time in 2010 with the initial development in roughly 2005. This website may not cover all aspects of what makes a LPD great, i'm a single person doing this out of passion from my research into LPD's. Also please note that any information contained on this website is my numbers and OPINION, data that could be wrong, please do your own research. I've done my part if you peak an interest into the technology. I've tried my best to verify data with AI to make sure I was trying to give correct information.
The WHY.
LPD's have all the benefits of modern monitors while also having all the benefits of the CRT, it's a total win win scenario. In fact there are few very important reasons why we should be advocating for the adoption and research of LPD's -

The below information is based on current power information.
1 - LPD - Using information based on what is called a "Prysm Tile", it's a 30 inch bezel less LPD Tile. (Constant - same as black screen).
2 - LED is a standard backlit 30 Inch LED Monitor. (Backlight is constantly on).
3 - WOLED - 30 Inches. (100% APL uses 3x more power than dark content).
Input Lag
You might be looking at this graph above and being confused why only the OLED has a bar. This is because CRT's and LPD's have near zero processing time. Now how is this possible, everything takes 'time' to do anything, and you are right, definitional context matters here.
There are two definitions, one is draw time, one is processing time. ALL modern displays currently being used by gamers (LCD,LED,OLED, etc). do what they call Sample and Hold. This means the display device holds the data, samples it and shows it on the display, holding that current frame while waiting for the next to finish sampling and being displayed, this takes time. A lot of time depending on the monitor. This is why when you play a game and you turn you see a massive blurry mess of pixels, you may not notice it as much anymore as that's what we are used too these days, but if you go back to a CRT Monitor it will be as clear as day. This is caused by one thing - Sample and Hold. Each monitor is different, but all modern monitors, do this. However, the LPD and CRT have 0 processing time. Literally 0, not even 0.1 Ms, absolutely nothing to the point the only measurable way is to find out how fast the electrons move through the vacuume of the CRT or the speed of which the electrons reach the laser for the LPD. Thats it. no holding data, processing it, etc.
But you may be wondering what this has to do with input lag, well it's simple really, if the monitor hasn't updated yet what happens? You wait for it to update to see the result of your input. And this here is the other definition. Draw time vs processing time + draw time. The LPD and CRT's just draw, no need to process any information.
G2G Response Times.
All OLEDs use (Gray-2-Gray) Response times on their response time metrics. This is NOT to be confused with INPUT RESPONSE TIMES. I really wish this metric wasn't worded as if input response times were this fast. This is the timing in which pixels can transition from shades. That is it. This has really made people think they are getting CRT/LPD response times when they aren't even close.
Motion Clarity
Tech | Pixel Response Time | Sample-and-Hold Duration | Motion Clarity (at 60 Hz) |
|---|---|---|---|
CRT | ~0.1–1 µs | ~0 ms (impulse-driven, near-zero persistence) | Near-perfect |
LPD (Prysm) | ~2–3 µs (phosphor decay) | ~0–1 ms (scanned laser, near-impulse) | Excellent — very close to CRT |
OLED (no BFI) | ~0.1–0.5 ms | 16.7 ms (full frame hold at 60 Hz) | Blurry — ~16.7 |
FPS | Hz (Monitor) | Frame Hold Time | Motion Blur (Eye Tracking) |
|---|---|---|---|
60 | 60 | 16.7 ms | Full blur (~1° at 30°/s) |
60 | 1000 | 16.7 ms | Still full blur — same 60 FPS hold |
1000 | 1000 | 1 ms | ~94% less blur |
1000 | 60 | 1 ms (strobing) | ~94% less blur (if V-Sync off) |
Motion blur = hold time of the source frame (1/FPS)
Monitor Hz only caps the maximum clarity — it can’t fix low FPS.
~0.1–0.5 ms | 16.7 ms (full frame hold at 60 Hz) | Blurry — ~16.7 ms blur |
Setup | FPS | Hz | BFI | Motion Clarity |
|---|---|---|---|---|
OLED | 60 | 1000 | Off | Blurry (16.7 ms) |
OLED | 60 | 120 | High BFI | Sharp (~4 ms hold) |
OLED | 1000 | 1000 | Off | Near-perfect (1 ms) |
LPD / CRT | 60 | 60 | Built-in | Perfect (~0 ms) |
The CONS
Now nothing is perfect and neither are LPD's unfortunately - Currently LPD's are big and heavy like their CRT cousins. According to AI research we can get LPDs down to < 2 inches in thickness. Of course do I think we will get that even when we get consumer grade monitors, no, but it is nice to know that with enough research it's possible to get them thinner.
