ubstrate and response time of liquid crystal.

matrix、color顯示用的著色pattern、保護著色pattern的透明保護膜、以及驅動液
晶用的透明電極膜等4種要素所構成。英：
In order for LCD to generate colors, there is a pattern with Red, Green
and Blue , which is one of the parts in the LC cell. Color filter is str
uctured by 4 major components: Black Matrix to block light, pattern to d
isplay colors, transparent protection film made from protection pattern
and transparent electrode film used for driver LC.
CIE chromaticity diagram

te. On the XYZ color graph and X10Y10Z10 color graph, it uses x, y or x1
0y10 direct coordinate, and they are called CIE1931 color graph or CIE 1
964 color graph. It is also known as xy or x10y10 chromaticity diagram.
COF
Chip On Film
直接將IC chip接續在可撓曲印刷電路板（flexible printed circuit board）的電
極端子上之方式，為Chip On Film的簡稱。此種IC構裝方法之特長為可撓曲印刷電

使用之接合方式有導電膜、導電膠及共晶接合。
英：

IC chip to the electrode terminal of flexible printed circuit board. Th
e specialty of this IC package method can thinner the flexible printed c
ircuit board, which is about one third of thickness of TCP. It also incr
eases the reliability of the liquid crystal display module. The current
connecting processes used are: conductivity film, conductivity paste and
eutectic conjunction.
COG
Chip On Glass
直接將驅動IC之I/O與顯示玻璃基板的電極端子面對面接合之方式，COG模組構裝所
使用之驅動IC必須先長凸塊(bumping)，液晶面板模組構裝之凸塊材質為Au，目前以
ACF為接合材料之製程較成熟。
英：
It is a process of connecting electrode terminal of display glass substr
ate and I/O of Driving IC directly to each other. The Driving IC must ha
ve bumping, and the material used for liquid crystal substrate bumping i
s Au. The manufacturing process, which uses ACF as its connecting materi
al, is more matured.
COP
Chip On Plastic
直接將IC chip接續在塑膠基板的電極端子上之方式，為Chip On Plastic之簡稱。
裝設塑膠基板液晶面板之driver IC時所使用的。
英：
It is a simplified term of Chip On Plastic, which is a method of connect
ing IC chip to the electrode terminal of plastic substrate. It is used f
or setting the driver IC onto the liquid crystal panel of plastic substr
ate.
Cold cathode fluorescent tube
Cold cathode fluorescent tube
為Back light其中一種光源，採用金屬陰極之螢光燈管。利用高電場引起發光放電
，然後用此放電所產生的紫外線激發螢光體而發光之放電燈管。基於發熱、壽命之
考量，大多採用冷陰極管。
英：
It is one of the light sources used in Back light, and it uses the fluor
escent tube of metal cathode. The discharge tube that uses high electric
al field to cause glow discharge and the ultra violet light generated fr
om this type of discharge would trigger the fluorescent particle and glo
w. Considering the heat and life time factors, the cold cathode fluoresc
ent tube is more frequently used.
Contrast ratio
Contrast ratio
液晶On╱Off時最大輝度與最小輝度之比。液晶依畫面視角的不同，其contrast也會
跟著改變，因此以最大的對比來表示。通常STN以10：1表示、TFT以100：1表示。
英：
The ratio between the maximum and minimum brightness when the LC is On /
Off. The contrast changes with different viewing angles, and therefore,
maximum contrast ratio is used for display. Generally, STN is 10:1 and
TFT is 100:1 for display.
CD
Critical Dimension
一般是指100um以下的pattern線寬或間隔，為表示pattern位置之尺寸值。使用於露
光量、現象條件、蝕刻條件等製程參數，或製品尺寸管理方面。
英：
CD means the gap or width between patterns under 100 um, and it is to sh
ow the dimension measurement of location of pattern. It is used as a par
ameter of light exposure quantity, and etching conditions in manufacturi
ng process or dimension management aspect of products.
Crosstalk
Crosstalk
由於畫素間信號干涉，使對比高的畫面輪廓在背景部產生的拖曳現象。每個畫素都
設置理想switch的主動矩陣方式不會產生crosstalk。

erate dragging phenomenon in high contrast screen. Cross talk can be eli

s and keeps in low BRIL status.
Data line
Data line
FT基板中傳達顯示信號之垂直方向的配線。因為接續在各畫素TFT的Source電極或D
rain 電極上，故又稱為Source線或Drain線。線寬通常為數um到10um不等。
英：
It is the perpendicular wiring used in TFT substrate to transfer display
signals. Because it is connected with the Source electrode or Drain ele
ctrode on each pixel in TFT, it is also known as Source line or Drain li
ne. The width of the line is often between few um to 10 um.
Dichroic Mirror

ed to projectors with poly-silicon LCD.

Driver IC
Driver IC

nning electrode (column electrode) Driver and Signal electrode (row elec
trode) Driver. The package of driver changes from QFP to TCP. The Driver
