Features of IGZO LCDs
IGZO LCDs employ oxide semiconductors (IGZO) com-
prising Indium (In), Gallium (Ga) and Zinc (Zn) to their
thin-film transistors (TFTs). This enables miniaturization
of TFTs compared to conventional amorphous silicon
TFTs and shrinking of wiring width, which allows for
increased light transmittance per pixel. These advances
make it possible to produce LCD panels that achieve
high-definition and low power consumption. In addi-
tion, the application of the UV2A technology*2 used in
AQUOS LCD TVs enables a high image quality.
Targeting Wider Applications
Not only for use in tablet terminals, Sharp anticipates the
application of IGZO LCDs to extend to high-definition
notebook PCs and LCD monitors—which are both ex-
pected to grow in demand. In addition, we also foresee
demand in new fields that are not an extension of con-
ventional applications, such as medical equipment. The
IGZO technology can also be adapted for use in OLEDs.
Sharp is creating new demand by offering one-of-a-
kind products employing its proprietary technologies,
such as IGZO and CG-Silicon technologies.
