Exploring RDS’s MIP Display Solutions:
Ultra-Low Power Reflective LCD for Always-On Applications
Memory-In-Pixel (MIP) displays, also known as Memory LCD or Reflective LCD with embedded SRAM, represent one of the most power-efficient display technologies available today.
By storing image data in memory at each pixel, MIP displays consume power only when the content actually changes and can retain a static image indefinitely with zero power.
We are one of the UK’s leading stockist and design-in partner for Sharp’s industry-standard LS-series MIP displays, offering the complete range from tiny indicators to high-resolution information panels.
Full Size Line-Up
We support the entire Sharp MIP portfolio and can supply every standard size:
- Ultra-small: 0.86″, 1.08″, 1.26″ – ideal for wearables, smart rings, and hearables
- Compact: 1.43″, 1.69″, 2.0″ – perfect for medical patches, remote controls, and metering
- Mid-range: 2.7″, 3.0″, 3.6″ – used in smart thermostats, bicycle computers, and industrial HMIs
- Larger panels: 4.4″, 5.5″ – high-resolution options for portable instruments and logistics scanners
Resolutions range from simple 96 × 96 on the smallest modules to crisp 400 × 240 or 480 × 480 on larger variants, delivering 100–200 ppi depending on size.
Key Performance Characteristics
- Ultra-low power: typically 10–30 µW in static mode (hundreds of times lower than TFT or OLED)
- Fully sunlight-readable reflective design – no backlight required
- High contrast (>25:1) and wide viewing angle (>170°) with anti-glare polariser
- Monochrome black/white (some models support 1-bit grey for simple shading)
- Operating temperature −20 °C to +70° C (industrial) or −30 °C to +80 °C (extended)
- Fast partial update capability (as low as 1 ms for small areas) enabling smooth gauges, cursors, and scrolling text
- Built-in 1-bit frame memory at every pixel – image stays visible with power completely removed
Shapes and Formats
While most MIP displays are rectangular or square, RDS can also supply:
- Round and circular versions (e.g., 1.26″ and 1.69″ diameter) – increasingly popular for smart home dials, watches, and control knobs
- Square formats (1.43″ 240×240, 2.0″ 320×320) – perfect for compact status panels
- Custom segment-style MIP – direct-drive numeric or icon displays for ultra-simple, battery-powered indicators
Add-Ons and Customisation Options
We transform standard Sharp MIP modules into complete, rugged, application-ready solutions:
Touch Integration
- Projected Capacitive (PCAP) touch – added via ultra-thin on-cell or out-cell sensors
- Resistive touch overlays for stylus or glove use
Cover Lens & Optical Enhancements
- Chemically strengthened cover glass (0.55 mm to 2 mm)
- Anti-glare, anti-fingerprint, or matte finishes to maximise outdoor readability
- Optical bonding for improved contrast and impact resistance
- Custom silk-screen printing – borders, icons, logos, or full branding
Mechanical & Metalwork
- Precision CNC-machined aluminium or stainless bezels
- IP65/IP67 front sealing for outdoor or wash-down environments
- Ultra-thin mounting frames (total depth <4 mm possible)
- Integrated coin-cell or super-cap holders for years of battery life
Drive & Connectivity Options
- Simple 3 V SPI interface with ready-made Sharp driver boards
- RDS-designed breakout boards with level shifters, flash storage, and RTC
- Wireless connectivity (BLE, NFC, or sub-1 GHz) for completely cable-free designs
- Full development kits including GUI software and example code
Why Choose RDS for MIP Display Solutions?
We hold buffer stock and have direct factory support, lead times are short and long-term availability is guaranteed – critical for medical, metering, and logistics applications that need 10+ year product lifecycles.
Whether you need a 1.08″ round MIP display that runs for five years on a single CR2032 for a medical patch, a 2.7″ square panel with PCAP touch and custom cover lens for a smart thermostat, or a rugged 5.5″ reflective HMI that stays readable in direct sunlight with almost zero power draw, we deliver the size, shape, and customisation expertise to make ultra-low-power, always-visible displays a reality.
