Problems solved by technology

[0005] However, due to the physical characteristics of the electronic paper display unit 100, its grayscale display is easily affected by temperature. If the temperature sensing unit 126 is arranged on the main circuit board 12, the temperature sensed by the temperature sensing unit 126 will not be able to truly reflect the temperature of the electronic paper display unit 100
Furthermore, different mechanism designs and placement positions of the temperature sensing unit 126 will affect the temperature of the electronic paper display unit 100 reflected by the temperature sensing unit 126

Abstract

The invention discloses an electronic paper display device. The electronic paper display device comprises an electronic paper display module and a main circuit board, wherein the electronic paper display module comprises an electronic paper display unit, a drive unit and a temperature sensing circuit; the drive unit is electrically connected with the electronic paper display unit; the temperature sensing circuit is arranged on the drive unit; the drive unit is used for driving the electronic paper display unit; the temperature sensing circuit is used for sensing the current temperature of the electronic paper display unit; the main circuit board comprises a substrate and a sequential control unit; and the sequential control unit is arranged on the substrate, is electrically connected the drive unit and the temperature sensing circuit and is used for controlling the drive unit to drive the electronic paper display unit by using driving parameters of the current temperature sensed by the corresponding temperature sensing circuit. The electronic paper display device can accurately sense the current temperature of the electronic paper display unit.

Description

technical field [0001] The present invention relates to an electronic paper display device, in particular to an electronic paper display device capable of accurately sensing the current temperature of an electronic paper display unit. Background technique [0002] At present, there are many electronic paper display devices specially used for reading on the market. Electronic paper is a conductive polymer material containing many tiny spheres (such as capsules). Its appearance and characteristics are the same as those of ordinary paper. It is flexible and can display data repeatedly. E-paper can use external light sources to display images, unlike liquid crystal displays that require a backlight, so in an outdoor environment with strong sunlight, the information on the e-paper can still be clearly seen without the problem of viewing angle. [0003] see figure 1 , figure 1 It is a functional block diagram of the electronic paper display device 1 in the prior art. Such as ...
