What is an IGZO display?

What is an IGZO display?

Indium gallium zinc oxide (IGZO) is a semiconducting material, consisting of indium (In), gallium (Ga), zinc (Zn) and oxygen (O). IGZO thin-film transistors (TFT) are used in the TFT backplane of flat-panel displays (FPDs). As a result, IGZO-TFT can improve the speed, resolution and size of flat-panel displays.

What is a-Si IPS?

A-Si is amorphous silicon, a material used in making TFT LCD. IPS, In-Plane-Switch is a way to control liquid crystal. So basically they are two different things.

Is LCD or OLED display better?

LCD displays used in TVs, computer monitors, phones and tablets use a backlight overlaid with a layer of liquid crystals. An Organic LED (OLED) screen uses light emitting diodes and works without a backlight. OLED screens provide better picture quality and consume less power but are more expensive.

Is an IGZO display a type of a display panel?

An IGZO display is a not a type of a display panel. To be more specific, an IGZO display is any display panel that uses a backplane thin-film transistor or TFT made of indium gallium zinc oxide or IGZO semiconductor material.

What are the advantages of IGZO TFT display?

Another benefit of IGZO TFT and thus, another advantage of IGZO display is less noise influence. This characteristic is based on the fact that an IGZO is an intermittent type of semiconductor. To understand further, note that the drive in an IGZO display does not need to be continuous. This allows touch input to be more sensitive or responsive.

What is an IGZO semiconductor?

An IGZO semiconductor has 30 to 50 times more electron mobility than amorphous silicon, thus allowing a smaller physical footprint without compromising conductivity. This higher electron mobility corresponds to more specific benefits.

What are the advantages of IGZO over LTPS?

The low current leakage and high electron mobility of IGZO give it a more advantageous current flow than aSi and LTPS. This advantage means that the transistors in an IGZO display do not have to be refreshed continuously while displaying a still image because it can retain the active state of its pixels longer due to its advantageous current flow.
