A cathode ray tube
No, a TV does not run on chemical energy. It typically runs on electrical energy, which is converted to light and sound to produce images and sound on the screen. The chemical energy is not directly used to power the TV.
Actually, the instrument that displays images of upward and downward changes in the membrane potential on a cathode-ray fluorescent screen is called an oscilloscope. A voltmeter is a device used to measure voltage at a specific point in a circuit.
In a literal sense no, but they have been detected experimentally. The fact that your television works is proof enough that electrons exist, since an electron is required to strike a screen in order to produce an image.
OLED burn-in occurs when certain pixels on the screen degrade faster than others, leading to permanent image retention. To prevent or minimize OLED burn-in, it is recommended to avoid displaying static images for extended periods, lower screen brightness, use screen savers, and enable pixel shifting features if available.
In a mobile device, the battery (chemical energy) converts into electrical energy to power the device. When the phone is being used, the electrical energy powers the various components of the phone, such as the screen, processor, and antenna.
A CRT (Cathode Ray Tube)
High energy electrons are an important part of the cathode ray tube which is part of the screen display you are currently looking at. They strike the phosphorus layer on the screen and produce the images.
A cathode ray tube uses an electron gun to produce a beam of electrons, which is then deflected by electromagnetic fields to create images on a screen. The electron beam is accelerated toward the screen, causing it to light up and produce the image we see. The deflection of the beam determines the position of each point on the screen, allowing for the creation of images and text.
It is both. The output device shows you images on the screen, while the input device allows you to interact with objects on the screen (e.g., touch the screen to select an option).
An electron gun is a device that emits a focused beam of electrons. It is commonly used in cathode ray tubes (CRT) in TVs and computer monitors to generate images by directing the electron beam onto a phosphor-coated screen, causing it to light up and produce images.
LCD monitor
Touchscreen. You see them every day on kiosks, cell phones, and PDA devices. The output is what you can see on the screen. The input is when you can control the device by touching images on the screen.
A fluoroscope is a device used to view continuous live X-ray images on a fluorescent screen.

A projector.
To customize the LG screen saver with pictures, you can go to the settings menu on your device and look for the display or screen saver options. From there, you can select the option to customize the screen saver with your own pictures by choosing images from your device's gallery or camera roll. You can also adjust settings such as the duration of the screen saver and how often it changes the displayed images.
