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.
