Electric paper display

Abstract

The invention discloses an electronic paper display including an electronic paper display screen. The electronic paper display is characterized in that the electronic paper display further includes a touch screen and a drive circuit; the touch screen is fixed above the electronic paper display screen; and the drive circuit detects the touched position of the touch screen and drives the electronic paper display screen to display correspondingly. The invention adopts the touch screen as the man-machine communication interface of the electronic paper display, thereby dispensing with an electronic pen, simplifying the input equipment of the electronic paper display, and facilitating carrying. A user can input on the touch screen by hand and can also use a common object to operate on the touch screen, so that the invention can be used whenever and wherever possible. The electronic paper display is more convenient to use, more visual to operate and wider to apply. The invention can further avoid scuffing the electronic paper display screen by the neb of the electronic pen and prolong the service life of the electronic paper display.

Description

technical field [0001] The present invention relates to an electronic paper display (Electronic Paper Display, EPD for short). Background technique [0002] Due to the advantages of low power, flexibility, and thin thickness, electronic paper displays are being widely used as display screens for electronic communication products such as mobile phones, e-books, computers, and personal digital assistants (PDAs). [0003] At present, most electronic paper display devices use an electronic pen as the input device of the display. There is a wire at the end of the electronic pen connected to the electronic paper display screen, which will cause inconvenience in use and carrying. In addition, during the writing process, since the tip of the electronic pen is in contact with the display screen of the electronic paper, it is easy to cause the display screen of the electronic paper to be scratched. Contents of the invention [0004] In order to overcome the above disadvantages, the...
