Abstract

The invention discloses an electronic paper display with a touch function, which comprises an electronic paper display body, a touch screen and a drive circuit used for testing the position of touched points on the touch screen and driving the electronic paper display for displaying. The touch screen is arranged on the electronic paper display, and the drive circuit is electrically connected with the touch screen while driving the electronic paper display for displaying. The electronic paper display adopts an input mode of the touch screen, thus being convenient when inputting, simultaneously, touch operation is carried out on the touch screen so that no damage can be caused to electronic paper; as the touch screen is arranged on a first substrate of the electronic paper directly, the touch screen and the electronic paper adopt the first substrate as a common carrier so as to reduce the thickness of the whole display; in addition, the light propagation efficiency can be effectively improved while the thickness is reduced, thereby improving the light transmittance of the whole electronic paper display.

Description

【Technical field】

[0001] The invention relates to an electronic paper display. 【Background technique】

[0002] At present, due to the advantages of low power consumption, flexibility, and ultra-thinness of electronic paper displays, electronic paper displays are being used in display screens of electronic communication products such as mobile phones, e-books, computers, and personal digital assistants.

[0003] Due to the development of mobile technology, many electronic devices begin to pursue simplicity and portability, and users can use them anytime and anywhere. At present, most electronic paper display devices use electronic pen as the input device of the display. This input device has a wire connected to the electronic paper at the end of the pen, which makes it inconvenient to write; , it is easy to cause scratches on the electronic paper. 【Content of invention】

[0004] The main purpose of the present invention is to provide an electronic paper display with a tou...
