What is a microcontroller?
A microcontroller or MCU is a computer-on-a-chip. It is a type of microprocessor dedicated to execute one task (as opposed to general purpose microprocessor), embedded in another device to control the features of that device thus, the name 'embedded controller'.

What is LCD? What is an LCD TV?
A display technology that uses rod-shaped molecules (that flow like liquid and bend light. Unenergized, the crystals direct light through two polarizing filters, showing a natural background color. When energized, the crystals redirect the light to be absorbed in one of the polarizers, causing the dark appearance of crossed polarizers to show. The contrast and viewing angle improve as the molecules are twisted further.
LCD TV
Liquid-colour display television (LCD TV) sets use LCD technology to display images. LCD TVs are lighter than CRT TV sets and consume less power.

What is an embedded system?
An embedded system refers to any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Embedded systems generally use microprocessors, or sometimes custom-designed chips or both. It is used in various applications such as vehicles, machine tools and consumer electronics.
