Active pen and touch system

Abstract

The invention discloses an active pen and a touch system, and belongs to the technical field of display. The active pen comprises a controller arranged on the pen body and an electrode located at theend of the pen body and connected with the controller. The controller is configured to control the electrode when the end part of the pen body where the electrode is located is in contact with a target area displaying the same color in the electronic ink screen; controlling the electrode to output a voltage signal. The voltage signal has a target polarity. The target polarity is the same as the polarity of charged particles which are located in the target area and on the display side in the electronic ink screen. When the end part of the pen body where the electrode is positioned is in contactwith the target area. The color displayed at the position in contact with the end part in the target area can be changed; The handwriting of the active pen can be formed in the target area along withthe movement of the end part in the target area, so that the active pen applicable to the electronic ink screen is realized, and the active pen not only can be applied to a traditional touch displayscreen, but also can be applied to the electronic ink screen, and is relatively high in use flexibility.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an active pen and a touch control system. Background technique [0002] With the development of touch technology, touch display screens have been widely used in people's lives. The touch display screen generally includes a touch panel and a display panel. The touch panel can determine a user's touch position, and the display panel can respond accordingly based on the touch position determined by the touch panel. In addition to performing touch operations on the touch screen with fingers, you can also use a stylus to perform touch operations on the touch screen. Wherein, the touch pen includes an active pen capable of outputting a voltage signal. [0003] The related technology provides an active stylus. The working principle of the active stylus is as follows: a touch panel is provided with a plurality of intersecting and insulated drive sensing lines Tx and touch sensing line...
