Monitor and display technologies

Dramatic improvements have been made in computer display technology in recent years. Chemists have developed liquid crystal materials, color filters, polymer alignment layers, molded-plastic light distribution sheets, and plasma display technology.

The structure of an LCD display

  1. Background lighting
  2. Glass
  3. Electrodes
  4. Liquid crystal
  5. Color filter
  6. Glass

The structure of an PLASMA display

  1. Data electrode
  2. Fluorescent subctance
  3. Noble gas mixture
  4. Screen electrode

The structure of an OLED display

  1. Metal Cathode
  2. Electron Transport Layer
  3. Organic Emitters
  4. Hole Injection Layer
  5. Anode
  6. Glass Substrate

First high-resolution color graphics screens are mainly based on the television's cathode ray tube. Liquid crystals displays (LCD) based on organic chemicals were invented in 1969.

Did you know?

One of the most promising display-technology solutions today is called E-ink or electronic ink. The display surface (electronic paper) is composed of several million tiny microcapsules, and ink or oily substance fills the microcapsules. In each of those microcapsules there are hundreds of smaller pigmented chips. When an electrical charge is applied to the microcapsules, the chips will either rise to the top or be pulled to the bottom. When pushed to the top, the chips make the capsules look white; when they are pulled to the bottom, the viewer only sees the dark ink. Patterns of white and dark can then be created to form words and sentences used in e-books or on the digital labels on the shelves of large department stores.
