Reference excerpt

Sony Digital Paper is a line of tablet-size E ink devices by Sony, aimed at business professionals to read and edit digital documents.

DPT-S1

The Sony DPT-S1 is a 13.3-inch (approaching A4) E ink e-reader by Sony, aimed at professional business users. The DPT-S1 Digital Paper can display only PDF files at their native size and lacks the ability to display any other e-book formats. The reader has been criticized for being too expensive for most consumers, with an initial price of US$1,100, falling to $700 at its end. The reader is lightweight and has low power consumption, a Wi-Fi connection, and a stylus for making notes or highlights. The DPT-S1 was released in Japan on December 3, 2013 and launched elsewhere in 2014. Sony announced the discontinuation of the DPT-S1 in late 2016.

Specifications The 13.3-inch e-Ink Mobius electronic paper screen has a resolution of 1200 × 1600 pixels, with a capacitive touchscreen. The device has an ARM Cortex-A8 at 1 GHz microprocessor. It was built on a SoC circuit made by Freescale. The amount of RAM was not published anywhere. Its internal storage, 4 GB, is shared between system and user; however, it is possible to expand the storage with a microSD card. It weighs 358 g (0.8 pounds) with a thickness of 6.8 mm. Novel to the DPT-S1 was the ability to interface with specific corporate networks by adding encryption, thus allowing legal professionals to make use of it in their workflow by integrating handwritten annotations into PDFs that could propagate when copied.

DPT-RP1 The Digital Paper DPT-RP1 was announced in April 2017. It features a 13.3-inch screen.

DPT-CP1 The DPT-CP1 from 2018 had a smaller 10.3-inch screen.

DPT-RP2 In 2023, Sony introduced the DPT-RP2.

Worked examples

Example 1 — a first encounter with Sony Digital Paper

Start with the simplest possible case. Write down what Sony Digital Paper 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 Sony Digital Paper 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 Digital Paper 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 Digital Paper

In research: Sony Digital Paper 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 Sony Digital Paper 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 Digital Paper is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Electronic paper technology, Sony hardware, so understanding it makes those chapters shorter.
In everyday life: Look for Sony Digital Paper 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.
