Product Picture
The YE042A88 excels in large-size color-coded scenarios with its
119 DPI display and 3-color capability. It vividly presents
classified information—red for promotions/urgent alerts, black for
detailed text/barcodes, and white for background—making it perfect
for large electronic shelf labels, logistics tags, and industrial
terminals. Its square pixel pitch (0.212×0.212mm) ensures sharp
text and clear barcodes, even multi-line content remains legible.
The hard-coat antiglare surface eliminates glare under direct
sunlight, maintaining readability in retail stores, warehouses, or
outdoor kiosks. With a slim design (1.15mm thickness) and
lightweight (15±0.5g) profile, it fits into space-constrained large
devices, while ultra-low power consumption (≤3μA deep sleep)
enables over 12 months of battery life for daily-updated
applications.
The YE042A88 is mainly designed for large Electronic Shelf Label
(ESL) systems with diverse industry applications. In retail, it
serves as large electronic shelf labels for home appliances,
furniture, and bulk groceries, using 3-color display to highlight
promotions (red), detailed product descriptions/prices (black), and
stock status (white background)—enhancing customer information
access and reducing manual label updates. Its low power consumption
reduces retail maintenance costs. In logistics, it functions as
large cargo tags, displaying complete waybills, transportation
statuses, and urgent markers (red for priority shipments),
withstanding -25~60℃ transportation for 10 days. In industrial
control, it acts as status monitors, indicating normal (white),
fault (black), and urgent (red) states for equipment. With ROHS
compliance and rigorous reliability testing (high/low temperature,
vibration, drop impact), it meets global environmental and
reliability demands for large-size e-paper applications.
Core Advantages
The YE042A88 features a 4.2-inch large active area (84.8×63.6mm)
with 400×300 high resolution (119 DPI), supporting 3-color display
for multi-level information classification. Its optical performance
is excellent: white state L*=63~65, black state L*=13~14, red state
L*=25~28 (a*=36~40), white reflectance 30~35%, and contrast ratio
10~15:1. The pure reflective mode saves power by eliminating
backlighting, while the hard-coat antiglare surface reduces glare
under direct sunlight. With an ultra-wide viewing angle, there’s no
color or brightness deviation from any direction, supporting
multi-person viewing for large shared devices like industrial
monitors or retail price tags.
Powered by bi-stable technology, the module only consumes power
during updates (max 180mAs at 25℃) and draws ≤3μA in deep sleep. A
standard lithium battery can power daily-updated large devices for
over 12 months, reducing battery replacement frequency. It
integrates the SSD1683 driver IC with on-chip booster/regulator,
generating VCOM, Gate (VGH/VGL), and Source (VSH1/VSH2/VSL)
voltages internally, simplifying external circuits. The
internal/external temperature sensor (I2C) enables real-time
waveform adjustment, ensuring stable operation in 0~40℃. It passed
rigorous reliability tests, including 240-hour high/low-temperature
storage, 168-hour high-humidity operation, and 50 temperature
cycles (-25℃~60℃), ensuring long-term use.
The module supports 3-wire/4-wire SPI (selectable via BS1 pin) and
I2C for temperature sensors, compatible with most MCUs and embedded
systems—no complex drivers needed. Pins 6 (TSCL) and 7 (TSDA) must
be grounded if external temperature sensors aren’t used (not NC).
The 24-pin 0.5mm ZIF Socket enables quick, secure installation. It
includes 10-byte OTP space for module identification, supporting
custom programming. The flexible FPC (0.10±0.03mm) with PI
stiffener (0.30±0.03mm) simplifies installation in non-flat large
device layouts, reducing development cycle and cost.
With an outline of 91.00×77.00×1.15mm and weight of 15±0.5g, the
YE042A88 is suitable for large-size device integration. The
hard-coat antiglare surface resists scratches and fingerprints,
while ROHS compliance meets global environmental standards. It
supports transportation temperature -25~60℃ (10 days) and storage
temperature 0~40℃ (max 5 years), adapting to harsh environments
like cold storage, warehouses, or outdoor retail. It passed
vibration testing (1.04G, 20~200Hz) and drop impact (100cm height
on concrete), ensuring durability during transportation and use.
The 5-year design life (25℃/60%RH, daily updates) guarantees
long-term reliable operation for large electronic shelf labels and
industrial devices.
