Abstract

The invention provides a method for judging the tilt direction of an electromagnetic pen, a method for calculating the vernier position of the electromagnetic pen, and a display device. The display device is capable of performing the method for judging the tilt direction of the electromagnetic pen and the method for calculating the vernier position of the electromagnetic pen. The method for judging the tilt direction of the electromagnetic pen comprises: supplying power to a plurality of antenna loops of the display device, finding out a reference antenna loop with the maximum induced voltage value, and using the induced voltage values respectively corresponding to the first right side antenna loop, the second right side antenna loop, the first left side antenna loop and the second left side antenna loop which are located on the left side and the right side of the reference antenna loop to judge whether the electromagnetic pen is in a rightward, leftward or vertical state relative to the display. Compared with an existing common electromagnetic pen inclination judgment method, the methods have better correctness, solve the problem that an existing electromagnetic pen inclination direction judgment method is prone to misjudgment, and greatly increase the speed of judging whether the electromagnetic pen is inclined or not.

Description

【Technical field】 [0001] The invention relates to a method for judging the inclination direction of an electromagnetic pen and a method for calculating the position of a vernier of an electromagnetic pen, in particular to a method for judging the inclination direction of an electromagnetic pen that is tilted to the right, tilted to the left or perpendicular to a display The judgment method, the calculation method of the cursor position of the electromagnetic pen. 【Background technique】 [0002] The existing method for judging the tilt direction of the electromagnetic pen is prone to misjudgment of the tilt direction of the electromagnetic pen, so that the display screen of the display device displays the cursor for marking the position of the pen tip of the electromagnetic pen at the wrong position, thus causing the user to Inconvenience to use. In addition, the existing method for judging the tilt direction of the electromagnetic pen requires more antennas for calculation,...
