LCC <QFJ>

Full spelling: Leaded Chip Carrier
Field:
Semiconductor > basis technology > LCC

One of package methods of IC tip/chip. Those which allot the pin for external input/output to the all around of the package. It has been similar to QFP, but form of the pin has become the letter type of J.

Those which used the ceramics are many in the package, but those which designate the package as the plastic call PLCC (PQFJ) with.

LCD <Liquid crystal display>

Full spelling: Liquid Crystal Display
Alias:
Liquid crystal monitor, liquid crystal monitor
Field:
Imaging > display > liquid crystal > LCD

The display which utilizes the liquid crystal. It encloses the special liquid between 2 plate glasses, it changes the direction of the liquid crystal molecule by applying voltage, it is designed to be the structure which indicates the image by the fact that it increases and decreases the transmissivity of light. The liquid crystal itself does not radiate, at the bright place reflected light, at the dark place the fluorescent light which is trained on back (back light) using light, does indication. To be large separately there is a simple matrix system such as STN system and DSTN system and the active matrix system of TFT and the like, but former cheapness efficiency latter one is high. Because liquid crystal display is light in comparison with other display such as CRT display and PDP being thin, it is widely used in the portable computer and the economical space desktop personal computer.

LCD television <Liquid crystal television>

Alias:
Liquid crystal TV and liquid crystal television
Field:
Imaging > display > LCD television

The liquid crystal at one of states of the substance which unites the flowability and solid (crystal) optical property of the liquid, encloses the substance of liquid crystal state between 2 plate glasses, changes the direction of the liquid crystal molecule by applying voltage, indicates the image by the fact that it increases and decreases the transmissivity of light. The SEIKO Epson developed the LCD television which applies this principle for the first time in 1987, but sharp sold “the window” is called the beginning in 1995 as a product for national welfare. Even presently sharp is the number one manufacturer of the LCD television which holds “the AQUOS” ([akuosu]) brand.
