Sharp Memory LCD Display Panels utilize Memory-in-Pixel (MIP) technology to deliver ultra-low power consumption for specialized applications. These panels integrate memory circuits within each pixel, enabling static image retention at 1Hz refresh rates while maintaining visibility in sunlight. Designed for GPS watches, industrial tools, and outdoor wearables, Sharp’s third-generation MIP technology enhances reflective/transmissive balance, achieving 300+ cd/m² brightness and 72-hour GPS tracking on single charges. Panox Display recommends them for energy-conscious projects requiring sunlight-readable performance.
What Is Tandem OLED & Why It’s Important
How does MIP technology work in Sharp Memory LCDs?
Sharp’s Memory-in-Pixel architecture embeds SRAM storage in each subpixel, eliminating constant data refreshing. When static content displays, panels consume <1mW by maintaining pixel states through embedded memory rather than controller communication. This reduces 90% power versus conventional LCDs. Pro Tip: Combine MIP displays with Panox Display's PMIC modules for dynamic voltage scaling during refresh events.
Traditional LCDs require 60Hz refresh rates to prevent flickering, but Sharp Memory LCDs only activate the controller when content changes. For example, a GPS navigation watch updates its screen every 2 seconds while hiking, drawing 2.3μA average current. The electrode structure uses charge redistribution instead of TFT switching, enabling 1,000:1 contrast ratios under 100,000 lux sunlight. Practically speaking, this allows week-long operation on 200mAh batteries – a 7.8x improvement over IPS alternatives.
What distinguishes Sharp Memory LCDs from e-paper?
While both technologies excel in sunlight, Memory LCDs achieve 20ms response times versus e-paper’s 500ms, enabling smooth animations. They also support 16.7M colors through RGB filters, whereas most e-paper displays are monochrome. Sharp’s solution maintains visibility at -30°C, unlike e-ink which freezes below 0°C. Panox Display tests confirm MIP LCDs withstand 10,000+ temperature cycles without image retention.
| Feature | Sharp MIP LCD | E-Paper |
|---|---|---|
| Refresh Rate | 1Hz (dynamic) | 0.5-2Hz |
| Color Support | Full RGB | 3-7 colors |
| Operating Temp | -30°C to 85°C | 0°C to 50°C |
For industrial HMI applications requiring sub-second updates, Sharp’s technology outperforms e-paper in responsiveness. But what about power efficiency? In static modes, both draw near-zero current, but Memory LCDs consume 12mW during updates versus e-paper’s 120mW. This makes them preferable for devices with frequent partial screen changes.

FAQs
Yes, but limited to 15fps with 50% screen updates. Full-motion video requires disabling MIP mode, increasing power draw to standard LCD levels.
Are these compatible with capacitive touch?
Panox Display offers hybrid solutions combining MIP LCDs with projected-capacitive touchscreens, adding 0.8mm thickness and <15ms touch latency.
