Samsung Vibrant Display Tear Down

So, after owning this phone for last 3 days and having gone through all the tweaks and hacks on this phone I decided to test the display quality of this phone. Working as a display test engineer for living, I have couple of tools handy for making the measurements and analysis. The primary measurements (for those interested) were made using Konica Minolta CS-200 Chromameter, Ocean Optics Spectrometer and Xeon Lit Microscope. Here are the interesting results:

Manufacturer: Samsung

Model #: SGH-T959

Pixels : 800x480

Display Technology: Super Active Matrix OLED

Color Bits: 24

Gray Levels: 256

Total Color: 16Million (2 to the power of # color bits)

Diagonal Size = 4"

Aspect Ratio: 1.6

Contrast Ratio: 8,22,800

White Point: (0.27,0.30) 9688K

Color Gamut: 103% of NTSC 1953

Transfer Function (Gamma Curve): 2.3



GRAY VALUES:



Spectra and Color Channels:







The angular measurement on the phone gives a clue that the OLED technology used in the Samsung phone is also the best in the market. They seem to be using micro-cavity since there is 5nm shift in peak wavelength with 30 degrees of rotation.



Its interesting how the display world is improving from LCD to OLED technology and this presents a beautiful picture of how Samsung Galaxy is one of the premier engineering achievements in the mobile phone industry.
