Embodiment Construction

[0036] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0037] Before introducing the technical solutions of the present application, the interaction process between the active capacitive pen and the touch display in the prior art is firstly described. figure 1 and figure 2 As shown, the touch electrodes in the touch display 01 will emit pulse signals on the display side, and the sensing electrodes in the active capacitive pen 02 will detect in real time whether the pulse signals on the display side are received. It means that the active capacitive pen 02 is close to the touch display 01, and then the touch coordinate driving electrodes in the active capacitive pen 02 transmit pulse signals. Due to the short distance, the touch electrodes in the touch display 01 can sense the movement from the active capacitance. The pulse signal on t...

Abstract

The embodiment of the invention provides a control method and device, a terminal, electronic equipment and a storage medium, relates to the technical field of touch control, and can effectively shorten the response time of first water output when an active capacitance pen interacts with a touch display. The touch display comprises a capacitive touch electrode and a pressure sensing module, and the control method of the touch display comprises the steps that when a touch coordinate positioning signal from an active capacitive pen is sensed through the capacitive touch electrode and a pressure condition is met, handwriting is displayed based on the touch coordinate positioning signal; satisfying the pressure condition comprises the step of sensing the pressure above the preset pressure value through the pressure sensing module.

Description

technical field [0001] The present application relates to the field of touch technology, and in particular, to a control method, device, terminal, electronic device and storage medium for a touch display. Background technique [0002] A stylus is an auxiliary device that uses conductive materials to imitate the human body (usually fingers) to complete human-computer interaction. At present, the stylus on the market is mainly divided into electromagnetic stylus and capacitive stylus, among which capacitive stylus is mainly divided into passive capacitive stylus and active capacitive stylus. Among them, the electromagnetic pen needs to be matched with the electromagnetic screen, and the overall cost is high; the passive capacitive pen is generally thick, and the writing has a sense of stagnation, and the user experience is not good; the active capacitive pen interacts with the touch display to realize the positioning of the stroke position. , and sense the pressure through th...
