What commenters say

• CRTs create the illusion of an image by rapidly drawing a raster pattern, which can be seen as a single bright dot when viewed at high speed.
• The persistence of phosphor in CRTs is a key factor in their motion clarity, but it drops off quickly, roughly within a millisecond.
• LCD/OLED displays have limitations, such as sample-and-hold and persistence blur, that can be mitigated with high refresh rates and strobing logic.
• Some argue that CRTs are better than LCD/OLED displays due to their ability to reduce persistence blur, while others point out the disadvantages of CRTs, such as power draw and limited development.
• The shadow mask in CRTs works by using parallax to direct the electron beams to the correct phosphor dots, with the mask holes and pigment dots positioned to ensure accurate color representation.
• Monochrome CRTs do not require a mask and can produce surprisingly sharp text, while color composite video has limitations on horizontal resolution due to the encoding of color information.
• The development of LCDs from research to consumer products was a challenging engineering process that required scaling up manufacturing and addressing issues like uniformity and defect sensitivity.
