Sharp LS013B7DH01 1.26 Inch Transflective Memory LCD Display Module for Smartwatches
The Sharp LS013B7DH01 is an advanced 1.26-inch transflective Memory LCD display module engineered specifically for battery-powered wearable devices and smartwatches. Featuring a perfectly square 128x128 resolution, this unique panel utilizes Sharp's proprietary Memory-in-Pixel technology, allowing it to maintain an always-on image with virtually zero power consumption. Unlike traditional OLED or TFT screens, its transflective nature means the display becomes brighter and clearer under direct sunlight, making it the ultimate choice for outdoor sports watches, fitness trackers, and industrial IoT sensors. Equipped with a simple SPI interface, the LS013B7DH01 is highly favored by hardware engineers, embedded developers, and DIY enthusiasts for rapid prototyping. Available now at ZY LCD Shop, we guarantee authentic Sharp panels, rigorous quality inspection, secure anti-static packaging, and fast global shipping. Build your next ultra-low-power device today.
Product Features
Proprietary Memory LCD Technology: Built-in memory at every pixel allows the screen to hold an image without continuous refreshing, resulting in ultra-low power consumption (microwatts).
True Sunlight Readability: The transflective design reflects ambient light. The brighter the environment, the easier it is to read, eliminating the need for a power-hungry backlight outdoors.
Always-On Display (AOD): Perfect for smartwatches and timekeeping devices that require the screen to be visible 24/7 without draining the battery.
Simple SPI Interface: Utilizes a standard Serial Peripheral Interface (SPI), making it incredibly easy to drive with popular microcontrollers like Arduino, ESP32, STM32, and nRF52.
High Contrast & Fast Response: Delivers crisp black-and-white text and graphics with response times fast enough for smooth UI animations in wearable applications.

Frequently Asked Questions (FAQ)
What is a Memory LCD and how does the Sharp LS013B7DH01 work?
A Memory LCD embeds a tiny memory circuit into every single pixel. Once an image is written to the Sharp LS013B7DH01 via SPI, the pixels hold their state without needing constant refreshing. This reduces power consumption from milliwatts (standard LCDs) to microwatts, enabling months of battery life.
Is the LS013B7DH01 readable in direct sunlight?
Yes, exceptionally well. Because it is a transflective display, it uses ambient light to illuminate the pixels. The brighter the sunlight, the higher the contrast and readability, making it superior to OLED or standard TFT screens for outdoor smartwatches.
Can I drive this 1.26 inch SPI display with an Arduino or ESP32?
Absolutely. The LS013B7DH01 uses a standard 3-wire or 4-wire SPI interface. There are numerous open-source libraries available for Arduino, ESP32, STM32, and nRF52 microcontrollers, making it very easy to integrate into your DIY wearable projects.
Does this panel have a backlight or color?
The Sharp LS013B7DH01 is a monochrome (black and white) display and does not feature a traditional backlight, as this would defeat its ultra-low power purpose. However, it can be paired with an optional front-light module if visibility in complete darkness is required.
