Sony Digital Paper DPT-S1 or Sony DPT-S1 was a 13.3-inch (approaching A4) E ink e-reader by Sony, aimed at professional business users.[3] The DPT-S1 Digital Paper could display only PDF files at their native size and lacked the ability to display any other e-book formats.[4] The reader had been criticized for being too expensive for most consumers, with an initial price of US$1,100, falling to $700 at its end.[5][failed verification] The reader was lightweight and had low power consumption, a Wi-Fi connection, and a stylus for making notes or highlights.[6][7] Sony announced the discontinuation of the DPT-S1 in late 2016.[8] Its successors are the Sony DPT-RP1 (released in 2017, 13.3-inch screen) and Sony DPT-CP1 (released in 2018, 10.3-inch screen), all inside the Sony DPT line of products.


The 13.3 inch e-Ink Mobius electronic paper screen had a resolution of 1200 by 1600 pixels, with a capacitive touchscreen.[9] The device had an ARM Cortex-A8 at 1 GHz microprocessor.[1] It was built on a SoC circuit made by Freescale. The amount of RAM was not published anywhere. Internal storage was 4GB that is shared between system and user, however, it was possible to expand this storage with a microSD card. It weighed 358g (0.8 pounds) with a thickness of 6.8mm. 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.
