Gas-Giant reality screens ( Same Idea works with all matter types )

Using gasses swirling around similar to a gas-giant to play moving images or static images, making a reality television because it does not create different colored light artificially as in light bulbs, LEDs, or television tubes, but instead emits light dependent on the different colors of the gasses, meaning reality plays the images. Gasses can be lit up in different energy levels to create more vibrant colors.

Solid and liquid would work similar to gas, and space would be for all matter types because all matter emits electrons or lower light particles. The brain would save all different types differently, getting different theories and outputs.

Your stylus would turn the electricity on and off. As the technology improved the pixels or pockets of gas would shrink, adding more definition to the screen. In the future of the technology you could run a micro pipe straight into the pixel and feed in any color, this would allow for rapid changes so moving pictures could occur. This would have been possible with a massive version with a small amount of pixels very quickly however. Using just mechanical technology, engineers from centuries ago could have made a music box device that pumped the different gasses, electrified, and then de-electrified the gasses in a predetermined sequence allowing for simplistic movies to be created far before modern technology, the person would have had to put in every pixel and craft every frame by hand just as our animators did long ago. These mechanical devices would have been used as something similar to a DVD or thumb-drive dependent on what was on it. If the device saved important information because the scientist used the movie as a moving scientific board set which they saved and improved their theories on, changing the mechanical device to alter the save file and improve their theories and ideas then it would be similar to a thumb-drive, or just entertainment if it was an ordinary movie or advertisement from long ago, then it would be similar to a DVD. Generals could save and build all their plans on the movie, stopping it at different board sets in the movie to work on them, or making moving ideas through sets of boards, save all their maps on one movie so all they had to do is play it and stop at the map they want. The devices would get smaller as scientists and others carried around all their ideas with them as if we carried around all our files on our computer in small thumb-drives which would be small mechanical devices similar to music boxes that play different screens of gasses in specific color combinations making pictures, or series of pictures that can be updated as you update the color box. Later technology would allow for changes on the screen to be automatically updated in the color box, instead of having to physically update the color box to change what was on the screen.

Advent Guard Note: They could have made functional calculator boards from gas before the 1800 century. As you write on the board it turns the gas you touch into plasma, making it stand out from the rest of the swirling gas. When you wish to change colors you empty the chamber of the gas inside and refill it with the color you want, as the lines you have already drawn stay there as plasma inside indents in the screen similar to pixels to keep them in position as electricity is pumped through on every side except the bottom and top holding the gas in place, as the rest of the gas leaves. As the technology improved and the lines became thinner and more precise it would eventually catch up to what could be done on boards. The screen would be able to be saved by keeping electricity running through it as you replace the screen with a new screen and put the old screen into savings.

Advent Guard Note: This time of history is known as the Gas screen period for the classified of Earth, or also known as the General is an asshole screen period because only rich people even knew this technology existed and got to use it to improve and build their and their families lives. But our books will probably just say the more fantasy steam punk version our scientists imagine as they make gas screen technology in the modern day, without realizing and truly understanding that scientists had to have had created gas screen technology centuries before on Earth in classified. Without the true knowledge of our history, our society can only possibly go in a different direction as the direction that the classified people are going, which makes us forever different.
