Sony XEL-1

Sony XEL-1 is a 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 Sony XEL-1 rather than just read about it. In short: The XEL-1 is the world's first organic light-emitting diode (OLED) television set, designed by Sony in 2007 and produced for sale the following year. It was also the world's thinnest television during its production, at 3 mm.

Key takeaways

Sony XEL-1 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sony XEL-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sony XEL-1 from memory before moving on to harder problems.

Reference excerpt

The XEL-1 is the world's first organic light-emitting diode (OLED) television set, designed by Sony in 2007 and produced for sale the following year. It was also the world's thinnest television during its production, at 3 mm. It has a screen size of 11 inches with a native resolution 960×540. The top of the base has 2 speakers and the power, volume, channel, input, and menu buttons, which are backlit, so the symbols and abbreviations change when the XMB interface is accessed. The back of the panel has a DMeX service input, a 16-volt DC input, a VHF/UHF/cable input, a Memory Stick slot, and two HDMI inputs. On the left side of the panel there is an analog/digital audio output. The XEL-1 has a contrast ratio of 1,000,000:1, high color saturation, large viewing angles, high screen uniformity, and low power consumption. On the other hand, it has poor primary color accuracy, a quarter of the full HD resolution (1920×1080), no anti-judder processing, a light-reflective screen, few inputs, a non-detachable panel, a small screen and a MSRP of US$2,499.99. It was sold in the United States, Canada, Russia, Japan, Europe and Australia. Years later in 2017, Sony officially sold their first large OLED TV in market, the BRAVIA OLED A1/A1E with 4K HDR.

Worked examples

Example 1 — a first encounter with Sony XEL-1

Start with the simplest possible case. Write down what Sony XEL-1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Sony XEL-1 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 Sony XEL-1 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 Sony XEL-1

In research: Sony XEL-1 appears in 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 Sony XEL-1 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: Sony XEL-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics OLED televisions, Products introduced in 2008, Sony products, so understanding it makes those chapters shorter.
In everyday life: Look for Sony XEL-1 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.
