Abstract

An active touch control pen comprises a touch-press element and a pressure sensing module; one end of the touch-press element is arranged at the nib of the active touch control pen and is used for receiving external pressure; the pressure sensing module is connected with the touch-press element and is used for generating oscillating signals; when the touch-press element receives external pressureand the external pressure is less than a first threshold value, the oscillating signal oscillates at a first frequency; when the touch-press element receives external pressure and the external pressure reaches to the first threshold value, the oscillating frequency of the oscillating signal is adjusted into a second frequency; the difference between the first frequency and the second frequency isgreater than the second threshold. According to the active touch control pen provided in the invention, by setting the threshold value of the external pressure, the active touch control pen can generate oscillating signals at first frequency and the second frequency which are different from each other according to that whether the external pressure reaches to the threshold value; therefore, the active touch control pen can avoid false point-report or water leakage caused by the active touch control pen due to noise disturbance of the external environment.

Description

technical field [0001] The invention relates to a touch pen, in particular to an active touch pen for frequency disturbance caused by noise. Background technique [0002] With the rapid development of the touch industry, the application of electronic products with touch functions is becoming more and more popular, such as smart phones, tablet computers, and car navigation devices. Users can input required information on such electronic products with the help of a stylus. Generally speaking, a stylus with pressure sensing capability generates corresponding information on the touch panel through pressure sensing. When the stylus is connected to the touch panel to sense the change of the external pressure, its sensing frequency also changes accordingly, so that the touch panel receives the signal from the stylus to generate relative handwriting. [0003] However, when the stylus is about to touch the touch panel, due to the interference of environmental noise or other reasons...
