Abstract

The invention provides an electronic paper display device. The electronic paper display device comprises an electronic paper display unit, a control unit, a storage unit, a satellite positioning reception unit and a power unit, wherein the control unit is electrically connected with the electronic paper display unit; the storage unit at least stores a piece of identification caution information and is electrically connected with the control unit; the satellite positioning reception unit is used for receiving the current satellite positioning information of an electronic paper display device and is electrically connected with the control unit; power unit is at least connected with the control unit; and when the power of the power unit is greater than or equal to a first power threshold value and smaller than or equal to a second power threshold value, the control unit loads the identification caution information of the storage unit and the satellite positioning information to the electronic paper display unit.

Description

technical field [0001] The invention relates to an electronic paper display device, in particular to an electronic paper display device that 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 (Electronic Paper) has the visual impression of imitating paper printing and writing, and its power consumption is extremely small. Electronic paper is different from ordinary flat-panel displays such as LCDs that require 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 w...
