Comparing with CRT, LCD display owns advantages of small size, thin frame, low energy consumption, low working voltage, no radiation, no twinkle and matching with CMOS integrated circuit.
(1) Electric saving, no high temperature
It’s a product with low electric consumption. It can produce no heat at all as the electric consuming and heat producing parts are in backlight tube or LED while CRT display inevitably produces high temperature due to its imaging technique.
(2) Thin frame, space saving
Comparing with heavy CRT, LCD has the space of only one third of CRT.
(3) Low radiation, good for health
The radiation from LCD is much lower than from CRT display, which is very good for people who always work with computer.
(4) Soft picture, no damage to eyes
Being different from CRT, pictures from LCD do not twinkle, which reduces the damage to eyes and protects our eyes from being tired. One material of LCD display is liquid crystal which is an organic compound between solid and liquid state. Liquid crystal gets transparent liquid state when heating and cloudy solid state when cooling. We control light changing by controlling electric field so that we can achieve picture display.
