2.9 Inch ESL Electronic Epaper Display Eink Digital Price Tag Shelf Label

2.9 Inch ESL Electronic Epaper Display Eink Digital Price Tag Shelf Label Product Description

SAEF Technology SFEPD290BW-7020A01 is a 3-Colors 2.9” a-Si, active matrix TFT, Electronic Paper Display (EPD) panel. The panel has such high resolution (112dpi) that it is able to easily display fine patterns. Due to its bi-stable nature, the EPD panel requires very little power to update and needs no power to maintain an image.

Storage Temperature TST:-20 - +60 ºC
Storage Humidity HST: 40%RH - 70%RH
Operating Ambient Temperature TOP: 0 - +40ºC
Operating Ambient Humidity HOP: 40%RH - 70%RH

70 %RH Max. (Ta ≦ 40 ºC), 40%RH Min. (Ta ≦ 60 ºC) where Ta is ambient temperature.
No condensation and no frost in absolute ratings of Environment.
The temperature of panel display surface area should be 0ºC Min. and 40ºC Max. Refresh time depends on operating temperature.
Reddish on the edge of black image is normal at high temperature.
Eink Material is Moisture and UV sensitive. The absolute rating operating environments describes the boundary conditions for updating the display while the absolute rating storage environment describe the boundary conditions for a display not updating. While displays are rated to perform according to specification for the warranty period at the absolute specified operating environment, the better the storage condition, the better the E Ink displays will perform. Similar to other moisture and UV sensitive components, we recommend that our displays be stored in temperature and humidity control environments, and whenever possible, under above defined Optimal Storage Condition, away from sunlight, to optimize their performance.

Analysis of AIoT's ESL solution

ESL, the full name of electronic shelf label (ESL), is a data collection portal of the Internet of Things, which collects multi-party interaction data, submits background analysis and outputs reports to improve operations. With ESLs as the core, each ESL is connected to the backend server/cloud through networking, in addition to real-time and accurate modification, display and recording of prices, goods names, barcodes, QR codes and promotional information, etc., so as to realize the digitalization of stores. Compared with traditional paper labels, ESLs have the advantages of reducing operating costs and improving management efficiency, which can improve the digital level of stores, improve customer experience, and achieve personalized marketing.

ESLs are composed of electronic ink screens, screen drive ICs, wireless communication modules, batteries, and resistor-capacitance sensors.

According to ePaper Insight statistics, in 2021, the number of global e-paper display modules (e-ink screens and modules) shipped will be about 180 million, of which more than 90% of e-paper modules are produced in Chinese mainland. The original manufacturers of electronic ink screens and modules mainly include Yuan Tai Technology E Ink, BOE, Aoyi, Plastic Logic, PERVASIVE DISPLAYS, Weifeng Technology, Jiaxian Electronics, Dianmo, Xingtai Technology (Xingtai Yingke, a subsidiary of Holitech), Qingyue Optoelectronics, Yashi Optoelectronics, Lianji Electronics, Dongfang Kemai, Mofang Optoelectronics, Dijing Optoelectronics, etc.

The main controller is a Texas Instruments MSP430G2553, a 16MHz MCU with 16KB flash memory, 512B SRAM, comparator, UART/SPI/I2C, and timer functions.

The selection of ESL main control chip is more inclined to integrate wireless communication functions:

For example, Texas Instruments' CC2640R2F, a SimpleLink™ 32-bit Arm Cortex-M3 low-energy Bluetooth® wireless MCU with 128kB flash memory and 275kB ROM;

Telink's TSLR835x is dedicated to 2.4GHz RF chip solutions;

SILICON LABS' EFR32FG22 (FG22) AND EFR32BG22 (BG22) SOCS SUPPORT THE 802.15.4 AND BLUETOOTH LOW ENERGY PROTOCOLS COMMONLY FOUND IN ESL AND DELIVER MARKET-LEADING RF PERFORMANCE IN TX POWER, RX, AND POWER;

RUNJET's RJM8L303 integrates 13.56MHz NFC functionality;

Rockchip's RK3566 comes with TCON-EBC, which does not require additional e-ink screen control chips;

N.X.P's Bluetooth BLE chip QN9021;

INGCHIPS' Bluetooth 5.1 LE chip ING918xx;

Nordic's Bluetooth chip nRF52832;

YICHIP's YC11XX SERIES;

INPLAY's IN610;

LENZE'ST17H65/ST17H62;

PHYPLUS'PHY6202;

UNICMICRO's UME3213, etc.

In the huge market of intelligent IoT AIoT trillion-level scale, ESL is only one of the products. If one day all the labels of chips in circulation use ESL, the industry will be really popular. Paiming Xincheng is a fast-matching component trading platform, and has accumulated an advantageous supply of IoT chips in the past few years. We focus on serving the long-tail customer base of components, making each chip of each chip manufacturer or distributor more efficient in Design In, Design Win and circulation, helping engineers to select, sample and procure, and making a modest contribution to the supply and demand of the electronics industry.
