Embodiment Construction

[0043] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0044] In view of the situation of the above-mentioned prior art, the inventors found that the traditional active capacitive stylus technology supports very little inclination angle, and all of them are plane angle recognition perpendicular to the touch screen plane, and do not support three-dimensional direction angle recognition. At the same time, the inventor also found that most active capacitive stylus signals are in a time-sharing transmission mode, and the time-consuming signal transmission and processing leads to a ...

Abstract

The invention discloses a touch pen, a touch panel, a touch system and a touch method. The touch pen comprises a processor, a first emitting electrode, a second emitting electrode and a third emittingelectrode, wherein the first emitting electrode, the second emitting electrode and the third emitting electrode are independently distributed in the extending direction of a stylus point of the touchpen. The processor comprises a processing unit and a transmitting circuit. The processing unit controls the first transmitting electrode to transmit a first signal, a second signal and a third signalthrough the transmitting circuit according to a first frequency, the second transmitting electrode to transmit a second frequency and the third transmitting electrode to transmit a third signal according to a third frequency. The first signal, the second signal and the third signal are received, so that the touch panel obtains space vector coordinates and / or direction angles of the stylus according to the received first signal, second signal and third signal; wherein the positions of the first emitting electrode, the second emitting electrode and the third emitting electrode are not on the same straight line, and the first frequency, the second frequency and the third frequency are co-prime frequencies. According to the embodiment provided by the invention, the touch precision of the active touch pen can be improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch pen, a touch panel, a touch system and a touch method. Background technique [0002] With the popularization of smartphones and tablet computers, more and more applications require the use of a stylus to achieve high-precision touch, and the performance requirements for the stylus are also getting higher and higher. With the advantages of high precision, low cost and high user experience, active capacitive stylus has become the most mainstream type of stylus. Different from the passive capacitive stylus, the active capacitive stylus itself is a signal source, so the sensor of the touch screen can receive the signal sent by the active capacitive stylus, so as to measure its azimuth coordinates, so that it is similar to handwriting The effect of pen writing on paper. [0003] The existing active capacitive stylus technology is generally divided into two types, one uses an ...
