LS044Q7DH01 4.4 Inch 320×240 Monochrome LCD Display Module for Industrial | SPI interface via 10-pin FPC for easy integration

Product OverviewThis 4.4-inch CG-Silicon LCD module (model LS044Q7DH01) is a specialized reflective monochrome display engineered by Sharp. Unlike traditional transmissive displays, this panel utilizes ambient light for illumination, eliminating the need for a power-hungry backlight. This makes it an exceptional choice for outdoor equipment, industrial handheld devices, POS terminals, and applications where sunlight readability and ultra-low power consumption are critical requirements.Display Specifications– Screen Size: 4.4 inch (diagonal) – Resolution: 320 × 240 (QVGA), 4:3 aspect ratio – Pixel Structure: Rectangle – Active Area: 89.6 (H) × 67.2 (V) mm – Physical Dimensions: 94.8 (H) × 75.2 (V) × 1.66 (D) mm – ultra-thin profile – Weight: 26.0g – exceptionally lightweightOptical & Performance Characteristics– Contrast Ratio: 18:1 (typical, reflective mode) – Viewing Angle: 60°/60°/60°/60° (typical, CR≥10) – Response Time: 10 ms (Tr, typical) / 20 ms (Td, typical) – Display Mode: TN, normally white, reflective – no backlight needed – Color Support: Monochrome Electrical & Interface Details– Interface: SPI via 10-pin FPC connector – simple digital communication – Power Supply Voltage: 5.0V (VDD) / 5.0V (VDDA) – Backlight: None (reflective design – utilizes ambient light) – Surface Treatment: Antiglare with hard coating (3H) for durability and reduced reflectionsEnvironmental Durability– Operating Temperature: -20°C to +70°C – Storage Temperature: -30°C to +80°C – Designed For: 3M (industrial/commercial applications)Package Includes1 × 4.4" Reflective LCD display module (LS044Q7DH01). Note: No backlight is included or required – this display is designed to operate using reflected ambient light. SPI interface requires proper initialization sequences. Please verify FPC pinout and SPI protocol compatibility with your system before installation. Touch panel is not included.

• Compact 4.4" QVGA Reflective Panel – Features 320×240 pixel resolution with a 4:3 aspect ratio and rectangle pixel structure. Reflective mode eliminates the need for a backlight, making it ideal for ultra-low-power and outdoor/sunlight-readable applications.
• Ultra-Thin & Lightweight Design – Exceptional slim profile with physical dimensions of just 94.8mm × 75.2mm × 1.66mm and weight of only 26.0g. Perfect for space-constrained portable devices, handheld terminals, and wearable equipment.
• Reflective Display Technology – Operates in normally white TN reflective mode, providing excellent readability in bright ambient light conditions. Typical contrast ratio of 18:1 (RF) with 60/60/60/60 viewing angles (CR≥10) – no backlight needed for clear visibility in sunlight.
• Low Power Consumption – No backlight means significantly reduced power draw. Operates on 5.0V (VDD) and 5.0V (VDDA) power supplies with 10/20 ms typical response time. Ideal for battery-powered and energy-sensitive applications.
• Easy Digital Interface – Standard SPI (Serial Peripheral Interface) via 10-pin FPC connector ensures straightforward integration with microcontrollers and embedded systems. Durable antiglare surface with hard coating (3H) for scratch resistance. Wide operating temperature range from -20°C to 70°C.
