Q: What is OLED?A: OLED stands for Organic Light Emitting Diode. OLEDs are relatively simple in structure, made up of an electrically active organic material sandwiched between an anode (a electron-releasing electrode) and a cathode (an electron-receiving electrode). When an electric current runs through the system, the anode sends electrons to the...

The Real Cost of Calibration

Calibration is the cornerstone of measurement confidence. Badly calibrated instruments are liable to produce measurement errors which can then propagate throughout an enterprise and even to the end-user’s product… and beyond! This can have a detrimental effect on a company’s reputation and profits, and could even have legal implications. The best w...

Eye to Eye. Whats new in test and measurement 2009

The transition from analogue to digital programme production, storage and delivery lulled some innocent folk into anticipating a world without need for test equipment. If required at all, so the thinking went, all signal analysis would be performed in software. Maybe someday. For now, the T&M sector remains alive and well. The following summary out...

Lighting. Back or rim light part 4

In my last article, I discussed modelling of the ‘talent’ by choice of lamp, and careful choice of the horizontal and vertical angle of the ‘key’ light. Having made those choices my next priority would be to choose a ‘back’ light. It is also sometimes known as a ‘hair’ light which gives a pretty good clue as to its function. Just to say that we are...

Monitor Colour Calibration

With the growing acceptance of LCD displays for high end picture monitoring it has become increasingly important that users can be assured that they are working to a known standard. The Xrite Eye-one is typical of the more simple probes available, and is similar to the probes used to calibrate computer monitors for reliable photographic processing....
