Zbd displays.ZBD liquid crystal display. Bistable displays have existed for decades (for example, electronic paper and cholesteric LCD), but due to some technical defects, this kind of display can not be widely used.
ZBD LCD is a bistable display based on traditional passive matrix LCD technology. The display was invented in the 1990s and has historically been mainly used for electronic shelf labels, while other applications such as electronic paper or cholesteric LCD have a smaller market. However, with the iterative development of technology, the current market demand for ZBD displays is growing, and some new applications include outdoor signage, parking meters, ticket / vending machines, smartwatches, keychains and so on. ZBD display is an ideal solution for battery-powered devices in some outdoor and bright lighting conditions.
Compared with other types of bistable displays, ZBD displays have many important advantages. First of all, the ZBD display can use the ordinary passive matrix LCD controller IC, these IC are cheap, easy to drive and long service life. Second, the development and NRE (Nonrecurring Engineering) costs of ZBD LCD are comparable to those of STN displays, and suppliers are able to supply customers with products of specific format and resolution with lower processing costs and minimum order quantity than TFT LCD. In fact, the only difference between the structure of ZBD displays and standard STN displays is an improved inner surface (which can be said to be an ideal supplement to NVD’s existing passive LCD production line). Third, ZBD displays do not have many of the limitations of STN displays, such as addressing and the number of driver lines. In addition, the ZBD display can achieve higher resolution without losing contrast or viewing angle. At present, the 14-inch ZBD display being produced by ZBD display Technology Co., Ltd. has a resolution as high as 200dpi, which is equivalent to the high-resolution TFT display. Fourth, ZBD technology does not require additional power to maintain the display screen (which is different from the most widely used TFT-LCD on the market), so its power consumption is extremely low.
Other important features of the ZBD display include paper-like reflectivity, wide viewing angle, daylight readability, extensive storage / operating temperature, and long-term stable cost. The display image can be perfectly switched at temperatures up to 85 °C, and there are no artifacts even at temperatures above 100 °C. At the same time, the display image can be switched at a temperature of-10 °C, and the display of the image can be maintained at a low temperature of-40 °C. In addition, NVD can customize and / or paste them with decorative and protective covers using the color print area behind the images. Because the technology is purely reflective, it must be illuminated from the front using ambient light or a front light guide, which is also a factory installation option provided by NVD.
