EMagin

EMagin is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand EMagin rather than just read about it. In short: eMagin Corporation is an American electronic components manufacturer based in Hopewell Junction, New York. eMagin specializes in organic light emitting diode (OLED) technology and manufactures micro OLED display used in virtual imaging products and other related products. Since the company's founding in 1996 it has developed and manufactured products for other various markets, including medical, law enforcement, rem…

Key takeaways

EMagin belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect EMagin to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of EMagin from memory before moving on to harder problems.

Reference excerpt

eMagin Corporation is an American electronic components manufacturer based in Hopewell Junction, New York. eMagin specializes in organic light emitting diode (OLED) technology and manufactures micro OLED display used in virtual imaging products and other related products. Since the company's founding in 1996 it has developed and manufactured products for other various markets, including medical, law enforcement, remote presence, industrial, computer interface, gaming and entertainment. For its microdisplays being incorporated in various military equipment such as night vision goggle and head-mounted display systems, the company has been a contractor to the U.S. military. In 2000, eMagin Corporation was named the winner of 2000 SID Information Display Magazine Display of the Year Gold Award, for technological advancement in the development of the organic light emitting diode (OLED) microdisplay technology, referred to as OLED-on-silicon. In October 2023, the company was acquired by Samsung Display in an all-cash deal worth approximately US$218 million and its stock was delisted from the NYSE American.

Z800 3DVisor

The Z800 3DVisor is a head-mounted display manufactured by eMagin since 2005. The main part of the Z800 is a pair of OLED displays with magnifying lenses producing a 40-degree diagonal field of view for each eye, used to display stereoscopic images with a fixed resolution of 800x600 pixels, through the use of the nVidia stereo 3D drivers, or, using later firmware revisions, any source of alternating frames. The visor can also be used as a 2D portable monitor on computers not equipped with an nVidia video card, using another operating system, or Macintoshes. The visor is equipped with a NEC TOKIN combined accelerometer/magnetometer/rate gyroscope 3-degrees of freedom motion sensor used to emulate mouse movements (typically to look around in first-person shooters), a pair of ear buds and an integrated microphone.

Worked examples

Example 1 — a first encounter with EMagin

Start with the simplest possible case. Write down what EMagin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to EMagin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about EMagin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of EMagin

In research: EMagin appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses EMagin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: EMagin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2023 mergers and acquisitions, Companies based in Bellevue, Washington, Companies established in 1996, so understanding it makes those chapters shorter.
In everyday life: Look for EMagin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is EMagin in simple terms?

Why does EMagin matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study EMagin?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
