LCD TVs
The Casio TV-10 was the first commercially-produced LCD TV. Though the invention of Liquid Crystal Display was credited to George Heilmeier in May, 1968, it was used in TVs in the early 1980s. More advances into the technology added improved resolution and better color saturation. LCD TVs were chosen as one of the top innovations for having pioneered improved viewing quality while staying affordable to the general public, winning over plasma TVs in these aspects. Although plasma TVs were able to deliver higher quality resolutions earlier compared to LCDs, the latter took over after the 90s, being able to render in 1080p, over plasma TVs’ maximum 720p. These displays also competed in terms of size, and the LCD was flexible in terms of smallest and largest sizes, with samples such as Sharp’s 108” LCD panel. Below is a short summary on how these work.
The display consists of two polarizing transparent panels and a liquid crystal solution sandwiched in between. The screen's front layer of glass is etched on the inside surface in a grid pattern to form a template for the layer of liquid crystals. Liquid crystals are rod-shaped molecules that bend light in response to an electric current — the crystals align so that light cannot pass through them. Each crystal acts like a shutter, either allowing light to pass through or blocking the light. The pattern of transparent and dark crystals forms the image. It's the same display technology behind your digital watch but way more sophisticated.

In August of 1981, Sony released the Sony Mavica (Magnetic Video Camera) electronic still camera. It marked the beginning of the digital camera, with its ability to record images taken into two-inch floppy disks and have photos viewed on a TV set or monitor. It started the replacement of film into an electromagnetic system, which gave way to the current digital cameras found in the market. Furthermore, digital cameras also made use of serial cables for more... [continues]
