Description

technical field [0001] The invention relates to an electronic paper display device, in particular to a wearable electronic paper display device which can display and identify warning information and satellite positioning information or transmit a satellite positioning signal according to the power level. Background technique [0002] Electronic paper has the visual impression of imitating paper printing and writing, and its power consumption is extremely small. Different from ordinary flat panel displays such as LCDs, e-paper needs to use a backlight module to emit light or a self-illuminating light source to achieve a display function, that is, it has a display function without a backlight module or a self-illuminating light source. Just like ordinary paper, electronic paper relies on ambient light to illuminate, so it is more comfortable to read, and the displayed image is still clearly visible in sunlight. In addition, the viewing angle is extremely wide, and its contrast...

Problems solved by technology

[0003] As the application of electronic paper is becoming more and more widespread, it has been further applied to electronic paper display devices such as wearable devices or portable electronic devices in recent years. Since these products are becoming lighter, thinner and smaller, they are easy to lose and difficult to find, so it is easy to cause damage.
