Core Technology
E-paper integration, low-power design and custom hardware, engineered as one working system.

CPU platforms
Self-developed image algorithms optimize display performance for faster refresh rates and reduced ghosting.

OS System
Accumulated Software technologies across multiple IOS software from android to Linux and RTOS system.

Low-power Consumption Design
Hardware and software are tuned as one system, so power is drawn mainly when the page changes and a single charge covers weeks of reading.

Ultra thin and light product design
Industrial design, 3D structure and internal layout are developed together, so a thin reading device still feels rigid in the hand and holds up in daily use.

Handwriting and Touch Experience
Stylus input, pressure sensing and low-latency ink are tuned together, so writing on an e-paper screen keeps up with the hand.
How we test
Every performance claim on this site comes from a defined test on a defined sample. Here is how those numbers are produced.
See our engineering teamSamples before claims
Performance figures are measured on pre-production samples from the same build that ships. Numbers quoted on this site are medians of repeated runs, not best-case readings.
Battery and power
Standby and reading runtime are logged with a fixed page-turn script at room temperature, and again after 200 refresh cycles to catch panel drift.
Display behaviour
Contrast, front-light uniformity and ghosting are checked on each panel batch, at low and high brightness, before firmware is locked for production.
Structure and durability
Thin devices go through drop, torsion and pressure tests on pre-production units. Failures are traced to a part or process, then re-tested after the fix.
End-of-line testing
Every unit runs a functional test before packing, and a sample from each batch goes through aging and a second full test so batch-level issues are caught early.
Insights
Notes on e-paper panels, devices and the reading market.

E Ink Carta 1400 might be pushed back to 2027
Industry sources have told Good e-Reader that the E INK Carta 1400 will be delayed until 2027, meaning Kaleido 4 and Gallery 4 won’t be released anytime soon.

Cutting the Cost of Digital Reading
Reading should always be a highly accessible and relaxing escape from reality. It should never transform into a hidden source of lingering financial stress
