TFT LCD (Thin Film Transistor LCD)
Is a thin film transistor LCD and is a type of LCD, a display element that uses optical switch
controlling the transmission of light by changing the arrangement of liquid crystal. Active
matrix type of flat plate display operates the liquid crystal by integrating TFT(thin film
transistor), an active switching element to each pixel of existing simple type LCD, and is
emerged as a powerful CRT substitute in PC areas including TV since it has excellent
resolution.
Resolution
Refers to precision level of device that displays graphics including graphic screen, TV
camera and plotter. In general, resolution of screen is determined by the number of pixels
at the horizontal points and vertical points forming the screen. The bigger the resolution of
screen is, the more it can display information and easier it can perform several tasks at the
same time.
Horizontal frequency
Number of horizontal frequencies that can be displayed for 1 second is called horizontal
frequency. The unit is Khz
Vertical frequency
Frequency of displaying the screen repetitively for 1 second is called vertical frequency.
The unit is Hz.
Pixel
Graphic screen can be separated into the row and column of small points and this small
point is called "Pixel". It is the smallest unit of screen that can be saved, displayed and
addressed.
Pixel pitch
Minimum diameter of LCD display is called "Pixel pitch".
For your reference, the distance between each pixel in CRT monitor is expressed as "DOT
Pitch".
OSD (On Screen Display)
When the user press the adjustment button to adjust the monitor screen status while data
is displayed in the screen, this function appears in the graphic form in the screen so that
the user can easily adjust it.
Plug and Play
This function is to automatically and easily adjust new hardware without separate
installation process.
