Memory in Pixel (MIP) technology embeds static memory cells directly within display pixels, enabling image retention without continuous refresh cycles. By storing grayscale or color data locally at each pixel, MIP displays drastically reduce power consumption—ideal for e-readers, smartwatches, and IoT devices. For instance, a 1.28″ MIP OLED with 128×64 resolution (1-bit depth) draws 10μW in static mode versus 1mW in conventional displays. Panox Display leverages this architecture to extend battery life by 300% in low-update-rate applications.
What Is Tandem OLED & Why It’s Important
How does MIP technology reduce refresh cycles?
MIP integrates SRAM cells at each pixel, allowing indefinite data retention. Unlike TFTs requiring 60Hz refresh rates, MIP updates only when content changes, slashing power usage. Pro Tip: Pair MIP with partial refresh algorithms to update specific screen regions, cutting energy 40% further.
Traditional displays constantly redraw pixels even for static images, draining power through unnecessary signal transmissions. MIP solves this by storing grayscale/color values locally. For example, a smartwatch using MIP might refresh just 0.1% of its screen per minute while showing time, consuming 0.5mAh/day versus 5mAh in standard LCDs. This localized memory approach also reduces electromagnetic interference from frequent data buses. But what happens if multiple zones update simultaneously? Panox Display’s MIP controllers stagger refresh timing to prevent current spikes exceeding 20mA.
What display types benefit most from MIP?
Devices with infrequent updates—e-readers, IoT sensors, and industrial HMIs—gain maximum efficiency. A supermarket e-price tag using MIP OLEDs from Panox Display lasts 5 years on a coin cell, updating prices twice daily.
High-resolution monochrome displays particularly excel with MIP. Consider a 2.9″ 296×152 E-Ink display: standard drivers consume 100mW per full refresh, while Panox Display’s MIP version uses 3mW. Transitional phrases like “Beyond grayscale applications” highlight emerging uses—MIP-enabled color OLEDs now achieve 16-bit color with 30% lower power than TFT counterparts. However, video-capable screens (30+ fps) see limited benefits due to inherent refresh demands.
| Display Type | Power (Static) | Power (60Hz) |
|---|---|---|
| MIP E-Ink | 0.02mW | N/A |
| TFT LCD | 50mW | 300mW |
| Panox MIP OLED | 0.1mW | 15mW |

FAQs
Initial costs rise 15-20% for memory integration, but lifetime energy savings offset this within 1-2 years for high-volume deployments.
Can MIP displays show animations?
Yes, but frame rates cap at 10fps optimally. Panox Display’s hybrid controllers allow switching between MIP and active modes for dynamic content bursts.
