Comparison of OLED with VFD

High Resolution

OLED provides dense graphics.


OLED materials are deposited directly onto the surface of glass substrate using a very high precision mask. This allows OLED to produce high resolution displays.


VFD requires mechanical parts to produce emitting devices. The accuracy of the mechanical parts is limited and this restricts the ability to produce high resolution displays.

* The above features are image graphics.

OLED is able to produce smooth moving graphics because the dot pitches of OLED are finely-detailed.

Thin Frame

OLED is loaded with space-saving features.


OLED layers are applied directly to the surface of the glass substrate and this allows the display area to be extended to the edge of the glass substrate, which is thin and light.


Due to the mechanical parts mounted around the display frame, it is difficult to reduce the frame thickness. Also, VFD needs thick, strong sealing glasses for vacuum encapsulation.

* The above features are image graphics.

OLED is a compact module due to its thin frame.

Wide Viewing Angle

OLED provides customers with a feeling of comfort due to its ease of reading.


OLED has wider viewing angles because the emitting area is the entire front surface.


Because the display surface is placed in a deeper position, the sealing frames and the grid frames make the viewing angles smaller.

OLED has higher level of visibility because of its wider viewing angles.

Low Power Consumption

OLED is eco-friendly, saving energy and reducing CO2 emissions.


Only the power needed to display the graphics is used, as required. The power consumption changes widely, depending on each lighting ratio.


VFD needs two power supplies one each for the graphics display and the filament. The filament power, which is a large percentage of the total, remains constant, regardless of the graphics displayed.

OLED has lower power consumption.
The lower lighting ratio gives OLED a significant edge over VFD.
