(TM),Viewing Angle is 80/80/80/80 (Min.)(CR≥10),Lamp Type is 4S2P WLED , Without Driver,Signal Interface is MIPI (2 ch, 4 data lanes) , 40 pins Connector,Brightness is 300 cd/m² (Typ.).Based on its characteristics, this model is recommended for application in and other products.The weight of LS029B3SX02 after packaging is 0.500KG.We have made every effort to minimize weighing variances; however, we cannot guarantee absolute accuracy.
Where can I purchase the LS029B3SX02 and what should I consider when designing with it?
A:
You can purchase it through electronic component distributors (such as Mouser, Digi-Key) or inquire directly from the manufacturer (e.g., Dalian Good Display). When designing, pay attention to: 1. Power supply and level shifting; 2. The impact of temperature on refresh speed (slower in low temperatures); 3. Strictly follow the timing requirements in the datasheet; 4. Reserve sufficient space and a mounting structure for the flex cable; 5. Correctly handle sleep and deep sleep modes to maximize power saving.
Q:
What is the main difference between the LS029B3SX02 and a common 2.9-inch 250x122 E Ink display?
A:
The most critical difference is the resolution. The LS029B3SX02 has a resolution of 1280x680, which is much higher than the common 250x122 screens. This means its pixel density is very high, resulting in extremely clear and sharp text and images without the graininess associated with common low-resolution E Ink screens. Therefore, it is suitable for displaying more complex and information-rich content.
Q:
How is the refresh speed of this E Ink screen, and does it have ghosting issues?
A:
E Ink screens have a relatively slow refresh rate. The full-screen refresh time for the LS029B3SX02 is typically between a few hundred milliseconds to one or two seconds, depending on the drive waveform and temperature. Ghosting is a common characteristic of E Ink displays, but it can be eliminated by periodically performing a full-screen refresh (clearing the screen). Properly configuring and optimizing the waveform lookup table in the driver is key to minimizing ghosting.
Q:
What interface does the LS029B3SX02 use and is it complicated to drive?
A:
This display typically uses a parallel 8/16-bit interface or a high-speed SPI interface. For beginners or simple projects, using the SPI interface is relatively easier, but the refresh rate is slower. To achieve a full-screen fast refresh, the parallel interface is required, which demands more GPIO pins from the microcontroller and is slightly more complex to program. The manufacturer usually provides reference code and drive waveform files (LUTs) to assist developers in driving it.
Q:
What are the main features and applications of the LS029B3SX02 display?
A:
The LS029B3SX02 is a 2.9-inch black and white E Ink display with a very high resolution of 1440x1440. Its key features are ultra-high definition, extremely low power consumption (only consuming power during refresh), and a paper-like viewing experience. It is ideally suited for devices that require long-term display of static content with high clarity, such as electronic shelf labels, industrial instrument panels, smart home control panels, and some high-end e-readers.
