           | Kind of like how especially well done science fair projects

           | parents handling most of the intricate work or otherwise

           | Eg 12 year old me could only throw together a solar powered

           | one who could do anything beyond resistor networks, but my
           | kids would be able to do much more advanced things because I
           | would be able to handle/simplify the complex stuff for them.
           | 
           | Another glaring example would probably be Sam-Bankman Fried.
           | No way would any person without the connections offered by
           | his parents have been able to get praised and handed billions
           | of dollars by investors for playing video games while
           | pitching to them.

       | A normal LCD screen works by shooting a backlight (usually LEDs)

       | backlight with either a reflective backlight, or ambient light if
       | it's bright enough.
       | 
       | So how could this be any improvement beyond just turning down the

         | There is no improvement. There are a lot of negatives though.
         | For starters:
         | 
         | * transmissivity of an LCD panel is pretty bad (10%-25%
         | transmissivity?). So this is always going to be extremely dim,
         | unless you stick a really bright lamp right up close to it.
         | Thus, this isn't "matching" ambient light in any way.
         | 
         | * Brightness uniformity is going to be terrible unless you use
         | a photography softbox lamp.
         | 
         | * Color accuracy is going to be terrible. Monitors use LEDs
         | that are extremely cold / blue (~6500K if I remember) to get
         | good color reproduction over the entire range of possible
         | colors. Unless you want your house to look like an operating
         | room you probably won't use a lamp that comes close to
         | reproducing that.
         | 
         | This is a solved problem in cellphones. Put a $0.25 ALS in the
         | front bezel, enable DDC/CI, and call it a day.
         | 
         | Here's a product idea that actually solves the issue: make a
         | little USB dongle that has an ALS in it, make it in a
         | formfactor that allows you to clip it to the top of any
         | monitor, and use that to control the brightness. For DDC/CI
         | monitors, you can directly control the backlight, and for other
         | monitors you can just fake it by reducing the brightness of the
         | image.

           | I actually did this exact thing, 20 years ago, with a monitor

           | a mirror with a diffuser on it (similar to what's shown), but
           | ended up using white paper on the back, and a light/window
           | behind, normal backlight style.
           | 
           | Why? Because, all your points are correct (although the lack
           | of uniformity was pretty ok/analog). And, as the images in
           | the article show, you can't get reasonable brightness without
           | a high powered light behind it. Oddly enough, the images in
           | the article, with the light above and a poor angled reflector
           | in the back, show _maximum possible_ blinding glare, with the
           | bulb shining right in your face.
           | 
           | It was temporary, fairly terrible, experience. A high quality
           | monitor, with auto brightness and ambient color matching
           | (like anything from Apple) would be my preference (and
           | current use).

       | Very hard to find an OLED monitor that doesn't have flicker (this
       | is not refresh rate - this is brightness modulating from 0 - 100%
       | hundreds of times a second - hard on eye muscles). Old CRT
       | monitors were even better than current OLED displays because the
       | flicker modulation was a curve and not a digital hard/on-off type
       | flicker.
