In some embodiments, the processor circuit 112 can be a touch control integrated circuit, and the invention is not limited thereto.

In some embodiments, the stylus 120 performs a touch operation on the touch screen 111. The processor circuit 112 generates at least one raw data based on the touch operation, and the processor circuit 112 further sets the graphic attribute corresponding to the touch operation based on the at least one original data value. For example, in an embodiment, the stylus 120 and the touch screen 111 have a specific touch area. When the stylus 120 performs a single touch on the touch screen 111, the touch screen is touched. At least one touch electrode of the 11 generates a touch signal based on the single touch, and the touch signal is transmitted to the processor circuit 112. The processor circuit 112 generates an original data value corresponding to the specific touch area according to the touch signal, and sets a graphic attribute corresponding to the single touch according to the original data value, for example, corresponding to the single touch The graphic properties are set to a black dot, a red rectangle, or a blue triangle having a specific pixel size, and the like. Specifically, when the touch pen having different touch areas between the touch screen 111 performs a single touch on the touch screen 111, the processor circuit 112 generates different originals due to different touch areas. The data values, and the different raw data values, cause the processor circuit 112 to set the graphic attributes corresponding to the single touch to different graphic attributes. Wherein, the above graphic attributes include a color, a shape or a combination of the above graphic attributes, and the invention is not limited thereto.

In an embodiment, the touch pen 120 and the touch screen 111 have a specific touch area. When the touch pen 120 performs a continuous touch operation with a line track on the touch screen 111, the processor circuit 111 A set of original data values are generated based on the continuous touch operation, and each of the original data values of the set of original data values corresponds to the specific touch area. Then, the processor circuit 120 sets the graphic attribute corresponding to the continuous touch operation as a black line based on the set of original data values. In this embodiment, if a second stylus has a second touch area between the touch stylus and the touch screen 111, and the second stylus performs a second continuation with a line trajectory on the touch screen 111. During the touch operation, the processor circuit 111 generates a second set of original data values based on the second continuous touch operation, and each of the original data values of the second set of original data values corresponds to the second touch area. Then, the processor circuit 120 sets the graphic attribute corresponding to the second continuous touch operation to a blue line based on the second set of original data values. Based on the above operation, when the stylus having different touch areas between the touch screen 111 and the touch screen 111 performs a touch operation on the touch screen 111, the processor circuit 112 performs a touch operation on the stylus with different touch areas. The corresponding graphic attributes are set to different colors.

In some embodiments, when the stylus with different touch areas between the touch screen 111 performs a touch operation on the touch screen 111, the processor circuit 112 touches the stylus with different touch areas. The graphic attributes corresponding to the control operations are set to different line handwritings, such as pen handwriting, brush writing, stylus writing, and the like, and the present invention is not limited thereto. In some embodiments, when the stylus with different touch areas between the touch screen 111 performs a touch operation on the touch screen 111, the processor circuit 112 not only touches the stylus with different touch areas. The processor circuit 112 sets the graphic attributes corresponding to the touch operation of the stylus with different touch areas to different line styles, such as physical lines, and the graphic attributes corresponding to the control operations are set to different line thicknesses. A dotted line or a bottom line or the like, and the present invention is not limited thereto.

In some embodiments, the pen tip 121 of the stylus pen 120 can have a plurality of pen tips, and the pen tip and the touch screen 111 have different touch areas. As shown in FIG. 2A to FIG. 2C , in this embodiment, the pen tip 121 of the stylus pen 120 can have three kinds of pen heads, respectively, the pen head 201 with the largest touch area; the pen head 202 with the second largest touch area; the touch area The smallest pen 203, and the present invention is not limited thereto. For example, when the stylus 120 performs a touch operation on the touch screen 111 using the pen tip 201 (as shown in FIG. 2A), the processor circuit 120 generates at least one original corresponding to the pen tip 201 based on the touch operation. Data value. The processor circuit 120 further sets the graphic attribute corresponding to the touch operation to a first color based on the at least one original data value. If the stylus 120 switches the stylus to the stylus 202 (as shown in FIG. 2B) and performs a second touch operation on the touch screen 111, the processor circuit 120 generates a corresponding stylus based on the second touch operation. At least one second source data value of 202. The processor circuit 120 further sets the graphic attribute corresponding to the second touch operation to a second color based on the at least one second original data value. Then, if the stylus 120 switches the pen tip to the pen tip 203 (as shown in FIG. 2C) and performs a third touch operation on the touch screen 111, the processor circuit 120 performs the third touch operation based on the third touch operation. At least one third source data value corresponding to the pen tip 203 is generated. The processor circuit 120 further sets the graphic attribute corresponding to the third touch operation to a third color based on the at least one third original data value. In some embodiments, the processor circuit 120 respectively performs the touch operation and the second touch operation based on the at least one original data value, the at least one second original data value, and the at least one third original data value. And the graphic attributes corresponding to the third touch operation are set to different line handwriting or line style, and the invention is not limited thereto.

In some embodiments, a touch area is provided between a stylus and the touch screen 111. If the stylus performs a touch operation on the touch screen 111, the touch area is changed due to different pen driving modes (for example, different angles or pressing forces), thereby causing the processor circuit 112 to misjudge the processing. The circuit 112 may set the graphic attribute corresponding to the touch operation to a plurality of graphic attributes. For example, a line having a plurality of colors, a line having a plurality of lines of handwriting, or a line having a plurality of line patterns. For example, in an embodiment, a stylus and the touch screen 111 are in a normal operation mode (for example, the stylus and the touch screen 111 are in contact at a specific angle or within a specific pressing force). During operation, the stylus and the touch screen 111 have a specific touch area. The stylus performs a touch operation on the touch screen 111 based on the specific touch area, and the processor circuit 112 generates a raw data value corresponding to the specific touch area according to the touch signal generated by the touch operation. And the above original data value is 50. In this embodiment, the processor circuit 112 sets the graphic attribute corresponding to the original data value between 30 and 40 to green; and sets the graphic attribute corresponding to the original data value between 41 and 60 to Red; and set the graphic property corresponding to the raw data value between 61 and 90 to blue. Therefore, when the user performs the touch operation on the touch screen 111 through the stylus in the normal operation mode, the graphic attribute corresponding to the touch operation is expected to be red. Then, in this embodiment, the touch pen and the touch screen 111 have a second contact area due to different pen movement modes (for example, different angles or pressing forces) operated by the user, and the touch The control pen performs a second touch operation on the touch screen 111 based on the second touch area. The processor circuit 112 generates a second original data value based on the touch signal generated by the second touch operation, and the second original data value is 63. In this case, when the user operates the stylus, the graphic attribute generated by the touch operation of the stylus is expected to be red, but the user may pass the touch under different operation modes. The pen performs a touch operation to produce an unexpected graphical attribute, which in this embodiment is unexpected.

Based on the above, in some embodiments, when a stylus performs a touch operation on the touch screen 111 and the touch operation is a single sliding track, the processor circuit 112 generates a set of originals based on the touch operation. Data values (eg 50, 51, 49, 56). At this time, the processor circuit 112 sets the graphic attribute corresponding to the first original data value of the set of original data values (for example, 50 of a set of original data values: 50, 50, 51, 49, 56) to the touch operation. The overall corresponding graphical properties, thereby avoiding unintended graphical properties. For example, if the graphic attribute corresponding to the first original data value generated by the processor circuit 112 is blue, a pen stroke or a broken line, the graphic attribute corresponding to the touch operation as a whole is blue. Color, pen handwriting or dashed lines.

In some embodiments, when a stylus performs a touch operation on the touch screen 111 and the touch operation is a single sliding track, the processor circuit 112 generates a set of original data values based on the touch operation (eg, 50, 51, 49, 52, 53). At this time, the processor circuit 112 sets the graphic attribute corresponding to the average value of the set of original data values (for example, a set of original data values: the average value 51 of 50, 51, 49, 52, 53) to the overall touch operation. Corresponding graphic attributes, thereby avoiding unintended graphic attributes. For example, if the graphic attribute corresponding to the average value of the set of original data values generated by the processor circuit 112 is red, a brush stroke or a solid line, the graphic attribute corresponding to the touch operation as a whole is Red, brush strokes or solid lines.
