Payment Type: T/T
TFT stands for "thin-film transistor." LCD stands for "Liquid Crystal Display." Both terms refer to the flat-panel display, or screen, of a computer monitor or television set. TFT displays are made using large sheets of transistors, each one of which is controlled independently. A TFT screen is an "active-matrix" screen where each pixel of the display is illuminated individually.A TFT display is sharper and brighter than a common Lcd Display. It refreshes more quickly than a regular LCD display and shows motion more smoothly.TFT displays use more electricity than regular LCD screens, so they not only cost more in the first place, but they are also more expensive to operate.

Note 1: Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L63 / L0
L63: Luminance of gray level 63
L0: Luminance of gray level 0
CR = CR (10)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note 5.
Note 2: Definition of Response Time (TR, TF):
The above “Viewing Angle” is the measuring position with Largest Contrast Ratio; not for good
image quality. View Direction for good image quality is 6 O’clock. Module maker can increase
the “Viewing Angle” by applying Wide View Film.
Note 4: Measurement Set-Up:
The LCD module should be stabilized at a given temperature for 20 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 20 minutes in a windless room.
