E-paper, also known as electronic paper, is a reusable display technology with a paper-like look and feel. It consists of microcapsules that can switch between black and white colors depending on the application of different electric fields. The performance of E-paper in different temperature environments will be affected to a certain extent.

First of all, E-paper can usually operate in a wide temperature range, usually from minus 10 degrees to 50 degrees. Also, higher temperatures may cause the E-paper to become insignificant, fail, or generate weak currents. This is because extreme temperatures may cause changes to the colloidal particles contained in the microscopic capsules, resulting in a decrease in display quality.

Second, as the temperature increases or decreases, the reaction speed of E-paper will also change. At low temperature, the reaction speed of E-paper is slow. Due to the influence of temperature, due to the reduction of its own chemical reaction rate, the response time is low, and the refresh of the display pattern becomes slower. At high temperatures, on the other hand, it has shorter reaction times and faster renewal rates, but also increases energy consumption because more electricity flow is required due to faster chemical reactions.

Third, changes in temperature will also affect the durability of E-paper. Under high temperature or low temperature conditions for a long time, the capsules in E-paper may rupture, causing the color contained in the capsules to overflow to the surrounding areas, making these areas lose their display function. Therefore, in view of the long-term operation of most applications of E-paper, in order to ensure its good performance and lifespan, it is necessary to place E-paper in an appropriate temperature environment.

In general, E-paper is less affected by air temperature, although in extreme temperatures, the response speed and display quality of E-paper may be affected to some extent. Therefore, in order to ensure its good performance and lifespan, the temperature environment needs to be considered when designing an E-paper display, especially some additional protection measures need to be taken under extreme temperature conditions.
