Product Picture
>
The YE075A42 excels in large-size color-coded scenarios with its
124 DPI resolution and 3-color capability. It vividly presents
dual-level information—red for promotions/urgent alerts, black for
detailed text/barcodes, and white for background—making it perfect
for electronic shelf labels, logistics tags, industrial control
terminals, and retail price signs. Its 800×480 high resolution and
7.5-inch large active area are tailored for displaying multi-line
rich information, such as product specifications, price tiers,
inventory status, and detailed descriptions. The hard-coat
antiglare surface eliminates glare under direct sunlight,
maintaining readability in retail stores, warehouses, or outdoor
kiosks. With a slim thickness of 1.1mm and lightweight design, it
fits into large-size device layouts, while ultra-low power
consumption (≤3μA deep sleep) enables over 12 months of battery
life for daily-updated applications.
The YE075A42 is mainly designed for large Electronic Shelf Label
(ESL) systems and industrial control with diverse industry
applications. In retail, it serves as large electronic shelf labels
for supermarkets, pharmacies, and bookstores, 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 3-color e-paper
applications.
Core Advantages
>
The YE075A42 features a 7.5-inch large active area (163.20×97.92mm)
with 800×480 resolution (124 DPI), supporting 3-color display for
dual-level information classification. Its optical performance is
excellent: white state L*=63~65, black state L*=13~14 (a*=3~5), 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 450mAs at 0℃, 250mAs at 25℃/40℃) 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 UC8179 driver IC with on-chip
booster/regulator, generating VCOM, Gate (VGH/VGL), and Source
(VSH/VSHR/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 BS 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.
Waveform is stored in on-chip flash memory, supporting custom
programming. The flexible FPC with PI stiffener (total thickness
0.30±0.03mm) simplifies installation in non-flat large device
layouts, reducing development cycle and cost.
With an outline of 170.20×111.20×1.1mm and weight of 44±0.5g, the
YE075A42 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.
