Electronic paper of integrated capacitive touch screen and driving method thereof

Abstract

The invention relates to electronic paper of an integrated capacitive touch screen and a driving method thereof. The electronic paper comprises a plurality of scanning lines, a plurality of touch induction lines, a plurality of mutual capacitors and a detecting circuit, wherein the scanning lines are mutually parallel, image scanning signals are input to the scanning lines in sequence and are used for conducting a thin film transistor connected with the scanning lines; the touch induction lines are mutually parallel and respectively intersected with the scanning lines in an insulated mode; the mutual capacitors are used for inducing whether the electronic paper is touched from the exterior or not; and the detecting circuit is used for detecting the capacitance variation of the mutual capacitors and is connected with the touch induction lines. Touch scanning signals are input to the scanning lines in sequence, and the time for inputting the touch scanning signals to the scanning lines is different from the time for inputting the image scanning signals to the scanning lines. The voltage of the touch scanning signals is lower than the conducting voltage of the thin film transistor, the detecting circuit detects the position of the mutual capacitor with capacitance variation, and thus, the touch position of the electronic paper from the exterior is determined.

Description

technical field [0001] The invention relates to an electronic paper integrated with a capacitive touch screen and a driving method thereof. Background technique [0002] Flat panel display technology has been widely used because of its small size and portability. E-paper and e-books made with E-ink technology conform to human reading habits. Compared with general flat-panel display technology, e-paper is less prone to fatigue after long-term reading and saves power. Compared with book paper, it has the advantages of large storage capacity, convenient search and environmental protection. Therefore, electronic paper technology has a good development prospect. [0003] see figure 1 , figure 1 It is a structural schematic diagram of an electronic paper display screen in the prior art. The electronic paper display screen 10 includes a thin film layer 11 and a substrate 12 arranged parallel to the thin film layer 11 . The common electrode layer 13 is disposed between the thin...
