DVDs do not contain magnets; they use a reflective surface and are read by a laser. LCDs (liquid crystal displays) may contain small magnets in their speakers or other components, but the display itself relies on liquid crystals and backlighting rather than magnetism.
Magnets are or rather were used to record audio or video on cassettes media earlier (which had/have magnetic tape in them on which data was recorded using magnet), which have now (still used) but taken over by optical media (CDs, DVDs, Blurays). Hard Disks/Drives in computer also use magnets to record on them.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
which is the cheapest magnets
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.

LCDs require less power than CRTs, they also do not flicker.

There are magnets in the motor that spins the disk, and there are magnets that move the reading head (laser) in and out on the disk as it plays. They are electromagnets - they only work if an electrical current is applied to the coil of the magnet.
An "LCD" is a Liquid Crystal Display. LCDs are used as parts of computer monitors and as displays in calculators, watches etc.
By stabing it in the face
CRTs (cathode ray tubes) and LCDs (liquid crystal displays) differ primarily in their technology and design. CRTs use electron beams to illuminate phosphor-coated screens, resulting in bulkier and heavier displays, while LCDs utilize liquid crystals and backlighting, making them thinner, lighter, and more energy-efficient. Additionally, LCDs offer better image quality, sharper resolution, and reduced flicker compared to CRTs. As a result, LCDs have largely replaced CRTs in modern display technology.
LCDs are much higher resolution.

Not noticeably. LCDs are very low-power.
indium is used to make thin film coatings which are used to make electronic devices as liquid crystal displays (LCDs). thin film coatings which are used to make such electronic devices as liquid crystal displays (LCDs). indium is used to make thin film coatings which are used to make electronic devices as liquid crystal displays (LCDs).
Non- LCDs are much better and cheaper to run!
