Memory In Pixel (MIP) displays are specialized low-power screens that integrate SRAM cells within each pixel to retain static images without continuous refresh cycles. Primarily used in e-readers, smartwatches, and IoT devices, they slash energy consumption by 80–95% compared to traditional LCDs. Panox Display’s MIP solutions leverage ultra-low refresh rates (0.1–1Hz) and sunlight-readable e-paper-like performance for applications prioritizing battery life over dynamic content.

How do MIP displays reduce power consumption?
MIP displays minimize energy use by embedding static image storage (SRAM) directly in pixels, eliminating constant data refreshing. This design allows screens to draw power only during image updates—ideal for devices like e-ink readers showing fixed text. Panox Display’s MIP modules consume just 0.5mW in standby versus 50mW for standard LCDs.
At the core of MIP technology are 1T1C (one transistor, one capacitor) or SRAM cells within each pixel. These cells retain grayscale or color data without external drive circuitry, reducing CPU workload and power-hungry signal transmissions. For example, a smartwatch using MIP might update its screen once per minute, cutting battery drain by 90%. Pro Tip: Pair MIP displays with partial refresh modes to update only changed areas, like a clock’s minute digits. But what if the display needs to show animations? MIP’s low 1–5fps refresh rate makes it unsuitable for video, highlighting its niche in static-focused devices. A real-world analogy: MIP screens work like sticky notes—once written, they stay visible without effort.
| Feature | MIP Display | Traditional LCD |
|---|---|---|
| Power Use (Standby) | 0.5mW | 50mW |
| Refresh Rate | 0.1–1Hz | 60Hz |
| Sunlight Readability | Excellent | Poor |
What devices benefit most from MIP technology?
E-readers, wearables, and sensors dominate MIP applications due to their need for persistent, low-energy screens. Panox Display supplies MIP panels for medical devices showing static vitals and retail shelf tags requiring monthly updates. Industrial control panels also use MIPs to maintain visibility in bright environments without backlights.
Beyond e-paper competitors, MIPs excel in always-on scenarios—like smartwatches showing time/notifications 24/7. They support 4–16 grayscale levels or limited color palettes, balancing readability with energy efficiency. For instance, a GPS tracker with a MIP screen can display location data for weeks on a coin cell battery. However, why aren’t smartphones adopting this tech? Limited color depth (typically 2–4 bits) and slow touch response (100–300ms) make MIPs impractical for interactive UIs. Pro Tip: Use MIPs in devices with infrequent user interactions to maximize battery gains. A real-world example: Panox Display’s 1.3” MIP module for smart thermostats updates temperature twice hourly, lasting 5 years on CR2032 cells.

FAQs
Yes, but with limitations—most MIPs support 4–8 colors via spatial dithering, unlike full-color OLEDs. Panox Display’s advanced MIP modules offer 4096 colors for basic icons in smart home panels.
Do MIP screens work with touchscreens?
Yes, but added capacitive layers increase power use by 15–20%. Use infrared touch for energy-sensitive projects to maintain MIP’s low-power advantage.
