TDK to mass-produce its See-through HD
organic electroluminescent display
TDK Corporation has started mass production of a newly
developed see-through passive matrix type QVGA organic EL
display from this Spring. TDK says this is the world's first
such product.
Organic EL displays are formed through thin-film techniques,
using organic material that emits light in response to an
electric current. Organic EL displays feature high brightness,
wide viewing angle and are easy on the eye. All organic
EL displays from TDK employ the passive matrix principle.
These Organic EL display are designed for use in mobile
phones and other such mobile devices.
The see-through type organic EL display for mobile applications
has a field angle of 2.4 inches, transmittance of 40 percent,
and brightness of 150 cd/m2. The newly developed product
is a see-through type, but is constructed so that the display
contents cannot easily be seen from behind, to protect the
user's privacy.
The display area of size is 36.0 x 47.9 mm and number of
pixels is 240 x RGB x 320.
The use of the color filter principle means that the service
life of the each Red, Green and Blue color of RGB elements
is identical, and color shift is absent. Furthermore, favorable
temperature characteristics allow a wide operating temperature
range from -20 to +85 degrees C.
