FIG. 1 is a flowchart of a touch display control method 100 according to an embodiment of the present disclosure.

In step S110, a touch pressure signal caused by a touch is received from the touch panel by the touch display control unit.

In step S120, information related to the touch pressure is obtained from the touch pressure signal by the touch display control unit. For example, data filtering or fitting operation may be performed on the touch pressure signal to obtain a corrected touch pressure signal, and based on the corrected touch pressure signal, information related to the touch pressure may be generated.

In step S130, the touch display control unit controls the display screen to display at least according to the information related to the touch pressure.

In this case, in step S130, the display screen may be controlled to display according to the information related to the touch pressure and the information related to the touch coordinates. For example, a corresponding display control signal may be generated based on the information related to the pressure and the information related to the touch coordinates, and the display screen may be driven to display by using the display control signal.

In some embodiments, the touch display control method 100 may further include: the touch display control unit transmits the touch display control result to the main control unit of the terminal device where the touch display control unit is located.

In some embodiments, the touch panel and the display screen may be integrated, for example, through incell or oncell technology. In some embodiments, the touch panel and display may be separate.

FIG. 2 is a flowchart of a touch display control method 200 according to an embodiment of the present disclosure. The touch display control method 200 is performed by a touch display control unit. The touch display control unit can be implemented by a single chip.

In step S210, a touch pressure signal caused by a touch is received from the touch panel. For example, the pressure sensor on the touch panel converts the pressure generated by the touch into a touch pressure signal, which is then received by the touch display control unit. Examples of pressure sensors include, but are not limited to, piezoresistors, piezoelectric sensors, and capacitive touch sensors.

In step S220, information related to touch pressure is obtained from the touch pressure signal. For example, the touch pressure signal may be corrected through data filtering or a fitting operation to obtain a corrected touch pressure signal, and based on the corrected touch pressure signal, information related to the touch pressure may be generated. As an example, the pressure-related information may include a pressure value or a pressure level. Typically 256 pressure levels are used. Through the correction, the detection accuracy can be improved, for example, false touches, such as touches on the touch screen caused by the terminal device being placed in the user's pocket, can be excluded. However, those skilled in the art should understand that the data filtering or fitting operations described above are only examples of correction methods, and the correction methods adopted by the embodiments of the present disclosure are not limited thereto.

As an example, if the pressure level is L1, a display control signal may be generated to increase the display brightness by one level; if the pressure level is L2, a display control signal may be generated to increase the display brightness by two levels... …and so on. As another example, if the pressure level is L3, a display control signal for unlocking the display may be generated.

The touch pressure signal and the touch position signal are received by the touch display control unit.

In step S320, information related to touch pressure is obtained from the touch pressure signal. For example, the touch pressure signal may be corrected through data filtering or a fitting operation to obtain a corrected touch pressure signal, and based on the corrected touch pressure signal, information related to the touch pressure may be generated. As an example, the pressure-related information may include a pressure value or a pressure level. Typically 256 pressure levels are used.

If the pressure level in block A2 is L1, a display control signal can be generated to increase the display contrast by one level; if the pressure level in block A2 is L2, a display control signal can be generated to increase the display contrast by two Levels of display control signals...and so on.

In step S360, the touch display control result is transmitted to the main control unit of the terminal device where the touch display control unit is located. Examples of the main control unit may include, but are not limited to, a main control chip of a terminal device, or a main control chip and its peripheral devices.

The touch display control method 300 can be applied to any touch display process that does not require the participation of the main control unit, such as adjustment of display characteristics such as brightness, hue and/or contrast of the display screen, screen unlocking, game control, and the like.

In addition, for the touch display process that must require the main control unit to participate, such as the interaction of the APP operation, the touch display control unit may, for example, after step S330, send the information related to the touch pressure and the information related to the touch coordinates to the host of the terminal device. The main control unit generates a corresponding touch display control signal based on the information related to the touch pressure and the information related to the touch coordinates and sends it to the touch display control unit, and the touch display control unit executes step S350 to utilize the Display control signals to drive the display screen to display. In this way, the embodiments of the present disclosure can be applied to various touch display controls on the one hand, and on the other hand, although the main control unit is involved, compared with the traditional method, the processing performed by the main control unit and the interaction with other components The interaction is still significantly reduced, the workload is still reduced, and the response speed is still improved.
