It is recommended that you first clarify what the "color display screen I am talking about" is? Is there a theoretical basis? Can it be manufactured? Does it really protect eyesight?
If it is just "the brightness is low during the day and the color display of the screen can be seen through the brightness during the day", then the light sensing system of the mobile phone has generally met your requirements. As long as we adjust the brightness of the mobile phone to the darkest and automatically adjust the brightness according to the light perception. However, this does not actually solve the vision problem! Because facing the screen for a long time will cause excessive eye fatigue and damage your vision! In other words, your idea is now available in the screen display function of smartphones, but it does not actually solve the problem of visual impairment.
At the same time, even if this hypothesis has never been realized, no scientist from ancient times to the present has been able to obtain national support just by proposing a hypothesis. Of course, if you are a rich man, then you can invest your wealth in the research of your hypothesis, find a bunch of scientists and precision instruments to conduct research and experiments, so as to realize the feasibility of the hypothesis and make it a reality! Any science should be rigorous. If you want to get support from the country, it is recommended that in addition to simple assumptions, you should make your ideas more complete, such as "theoretical basis of the idea", "feasibility", "actually achievable" Application" etc. After all, there are so many Chinese people with 1.3 billion simple ideas? Isn’t it enough to be choked after reading this? Of course, we can ask for help from computers. Still, do you think your "color display like I said" can really stand out among 1.3 billion ideas?
Finally, after carefully reading your introduction to the problem, I feel that you should start from reality, first determine whether it is feasible, write a report and then apply for a patent. Of course, in the research, you can refer to the "light" of smartphones. "Automatic sensor adjustment function" is similar to your description.
In addition, to improve your writing skills, you can use more punctuation marks. For example, you can use "double quotation marks" to express emphasis or quote other people's language. Don't be like now, with more than a hundred words in the paragraph and not a single "comma". This will cause certain reading difficulties! The article does not have to be literate, but it does not have to be fluent! If your article makes other people dyslexic, how do you express your thoughts?
