Organic Light Emitting Diodes (OLED) are being developed for the next generation
of displays and light sources. The QDI 302 microscope spectrophotometer, from
Technologies, is designed to measure and compare the spectral output, intensity
and color consistency of each of the microscopic pixels commonly found in OLED
Organic light emitting diodes (OLED) have an emissive electroluminescent layer
that consists of organic molecules in a supporting matrix. For displays, this
layer is formed into millions of microscopic pixels in ordered rows and columns.
As different organic compounds are used to generate different colors, pixels
with different organic compounds can generate different colors for full color,
high resolution displays. The biggest advantages of the OLED devices, u nlike
the traditional Liquid Crystal Displays (LCD), is that the pixels combine both
the light source and the color source. This means that OLED displays are lighter
and thinner and use less electricity than an LCD. However, consistency of the
intensity and the color of the optical emission across the device is critical.
This is where instruments such as the QDI 302 spectrophotometer for microscopes
The QDI 302 is a spectrophotometer that is designed to add to the open photoport
of a microscope or probe station. It allows the user to acquire images and acquire
spectra of microscopic sample areas quickly and rapidly. When added to the appropriate
microscope or probe station, the QDI 302 can be used to measure the color and
intensity of each pixel of a OLED display. Pixels can then be compared with
one another for consistency or maps of both the intensity and color can be generated
for each device. And as instruments such as the QDI 302 can acquire spectra
on the order of a few milliseconds, entire OLED displays can be mapped quickly
and accurately. This will ensure the consistency of both color and intensity
across the entire device as well as from device to device.
