[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figure 1-4 , Figure 1 A schematic diagram of the driving layer of the touch panel in an embodiment of the present invention is shown. Figure 2 A schematic diagram of the receiving layer of the touch panel in an embodiment of the present invention is shown. Figure 3 A schematic diagram of the driving sensor of the touch panel in an embodiment of the present invention is shown. Figure 4 A schematic diagram of the receiving channel, coordinate detection driving channel, and acceleration driving channel of the touch panel in an embodiment of the present invention is shown.

[0057] Specifically, the touch panel 4 includes a driving sensor, which comprises a receiving layer 1 and a driving layer 2. The receiving layer 1 includes a plurality of receiving channels 11 and receiving connection lines 12. Each of the plurality of receiving channels 11 is parallel to each other, and each of the plurality of receiving channels 11 includes a plurality of receiving blocks 111 connected in sequence. The driving layer 2 includes a plurality of coordinate detection driving channels 21, a plurality of acceleration driving channels 22, acceleration driving graphic connection lines 23, and coordinate detection driving graphic connection lines 24. Each of the plurality of coordinate detection driving channels 21 is parallel to each other, and each of the plurality of acceleration driving channels 22 is parallel to each other. Each coordinate detection driving channel 21 includes a plurality of coordinate detection driving graphics 211. Channel 22 includes several acceleration driving patterns 221; the several acceleration driving channels 22 and the several receiving channels 11 are stacked in a cross manner, and adjacent acceleration driving patterns 221 and receiving blocks 111 will have intersecting nodes, and a capacitance will be formed between the acceleration driving pattern 221 at each node and the adjacent receiving block 111; the several receiving channels 11 are connected to the receiving connection line 12, the several acceleration driving channels 22 are connected to the acceleration driving pattern connection line 23, and the several coordinate detection channels 21 are connected to the coordinate detection driving pattern connection line 24, so as to facilitate the connection of FPC line 3 through the acceleration driving pattern 221 connection line, the receiving connection line 12 and the coordinate detection driving pattern connection line 24, so as to achieve the purpose of connecting with external signal processing equipment; the driving sensor is formed by the receiving layer 1 and the driving layer 2 being centrally attached, and the driving sensor has the function of touch display.

[0058] It should be noted that on the same receiving channel 11, two adjacent receiving blocks 111 are connected through receiving node bits, and on the same acceleration driving channel 22, two adjacent acceleration driving patterns 221 are connected through acceleration driving pattern node bits. The receiving node bits and acceleration driving pattern node bits form intersecting nodes.

[0059] Furthermore, the acceleration driving pattern 221, the coordinate detection driving pattern 211, and the receiving block 111 are all rhomboid in shape, and the shape and size of the acceleration driving pattern 221 are the same as those of the receiving block 111. This makes the adjacent positions of the receiving block 111 and the acceleration driving pattern 221 relatively flat, which facilitates the control of the capacitance formed between the receiving block 111 and the acceleration driving pattern 221.

[0060] Furthermore, the coordinate detection drive channel 21 and the acceleration drive channel 22 are oriented horizontally, and the coordinate detection drive channel 21 and the acceleration drive channel 22 are emission electrodes.

[0061] Furthermore, the direction of the receiving channel 11 is vertical, and the receiving channel 11 is a receiving electrode.

[0062] It should be noted that the touch principle is as follows: Each intersection of a horizontal and vertical channel generates a relatively large inductive capacitance. When an electrical pulse of a certain amplitude is applied to one of the transmitting channels, all receiving channels will receive this signal through the inductive capacitance at the intersection. The signal at the intersection is only related to the position of the transmitting channel. If all transmitting channels are scanned using the above method and the received information at each intersection is recorded, when an intersection is touched by a conductor of a certain area or a finger, a portion of the inductive voltage at the intersection is discharged to ground. By calculating the coordinates of the intersection, it is possible to determine which one or more intersections were touched.

[0063] Furthermore, the driving layer 2 and the receiving layer 1 are bonded together with optical adhesive, which is a polymeric substance with optical properties similar to those of optical components and excellent bonding properties, thereby achieving the purpose of bonding the driving layer 2 and the receiving layer 1 into an optical component that meets the requirements of the optical path design.

[0064] Furthermore, the coordinate detection drive channel 21, the acceleration drive channel 22, and the receiving channel 11 are all made of conductive material, which is ITO transparent conductive material. This material is both a conductor and does not affect the content of the display.

[0065] Furthermore, the acceleration driving graphic 221 and the coordinate detection driving graphic 211 are arranged alternately in sequence.

[0066] It should be noted that the acceleration driving graphic 221 is divided into an upper half screen and a lower half screen, which are electrically connected in parallel through edge lines. When a touch operation is performed on the upper half screen or the lower half screen, the acceleration driving graphic 221 does not need to run on the entire screen. It can autonomously determine the location of the touch point and drive only the acceleration driving graphic 221 of the upper half screen or the lower half screen to achieve the purpose of regional driving detection acceleration.

[0067] Furthermore, the acceleration driving graphic 221 and the coordinate detection driving graphic 211 are located on the same plane or on opposite sides.

[0068] It should be noted that the acceleration driving graphic 221 and the coordinate detection driving graphic 211 can be made on the same plane or on opposite sides.

[0069] Furthermore, the receiving layer 1 and the driving layer 2 are also provided with FPC lines 3. The terminals of the acceleration driving graphic connection line 23 are connected to the FPC lines 3, and the terminals of the receiving connection line 12 are connected to the FPC lines 3, so as to achieve the purpose of connecting with external signal processing equipment.

[0070] More, Figure 5 A flowchart of a control method for a touch panel according to an embodiment of the present invention is shown. The method includes:

[0071] S51 When a user is detected operating the touchscreen, the touch signal of the user's touch operation on the touchscreen is acquired and the touch signal is transmitted to the receiving sensor for preprocessing.

[0072] Furthermore, the preprocessing includes: performing low-pass filtering on the touch signal.

[0073] It should be noted that low-pass filtering only allows signals below the cutoff frequency to pass through, while signals above the cutoff frequency are not allowed to pass through. This limits the signal frequency and improves the accuracy of the signal.

[0074] S52: The preprocessed touch signal is transmitted to the receiving and processing unit. The receiving and processing unit processes the preprocessed touch signal to obtain the comparison signal and touch area information, and transmits the touch area information and the comparison signal to the processor MCU at the same time.

[0075] Specifically, the receiving and processing unit acquires touch area information and touch capacitance information based on the preprocessed touch signal; the receiving and processing unit records the touch capacitance information and compares it with the previously recorded touch capacitance information to obtain a comparison signal.

[0076] Furthermore, a microcontroller unit (MCU), also known as a single-chip microcomputer or microcontroller, is a chip-level computer that appropriately reduces the frequency and specifications of a central processing unit (CPU) and integrates peripheral interfaces such as memory, timer, USB, A / D converter, UART, PLC, DMA, and even LCD driver circuitry onto a single chip, forming a chip-level computer that can perform different combinations of control for different applications.

[0077] It should be noted that each continuous touch contains several touch capacitance information, and the comparison signal refers to the change value between each adjacent touch capacitance information.

[0078] S53: The processor MCU determines whether the touch signal is a valid touch based on the touch area information;

[0079] Specifically, the processor MCU sets a touch area reference value; it determines whether the touch area information is less than the touch area reference value; if so, the touch signal corresponding to the touch area is determined to be an invalid signal; if not, the touch signal corresponding to the touch area is determined to be a valid signal.

[0080] Furthermore, after the touch signal corresponding to the touch area is determined to be an invalid signal, the method further includes: returning to real-time detection of the touch screen, and acquiring the touch signal of the user's touch operation on the touch screen when the user is detected to be operating the touch screen.

[0081] Furthermore, the reference value for the touch area is the area of ​​touch tools such as fingers and capacitive pens.

[0082] S54: If valid, the processor MCU detects the position of the touch signal based on the comparison signal; the position of the touch signal includes: upper half screen, lower half screen, and full screen;

[0083] S55: Based on the position of the touch signal, obtain the coordinate detection driving graphic and the acceleration driving graphic corresponding to the touch signal, and transmit the coordinate detection driving graphic and the acceleration driving graphic to the processor MCU;

[0084] Specifically, the coordinate detection driving pattern corresponding to the touch signal is obtained based on the sequential changes in the position of the touch signal; the acceleration driving pattern required for the touch signal to pass through the acceleration driving channel is obtained based on the sequential changes in the position of the touch signal; and the coordinate detection driving pattern and the acceleration driving pattern are transmitted to the processor MCU.

[0085] Furthermore, when the touch signal is emitted in the upper half of the screen, the processor MCU controls the drive control unit to drive the coordinate detection drive channel of the upper half of the screen to obtain the coordinate detection drive pattern of the coordinate detection drive channel; when the touch signal is emitted in the lower half of the screen, the processor MCU controls the drive control unit to drive the coordinate detection drive channel of the lower half of the screen to obtain the coordinate detection drive pattern of the coordinate detection drive channel; when the touch signal is emitted in the entire screen, the processor MCU controls the drive signal according to the timing control logic to determine the order of the coordinate detection drive channels to obtain the coordinate detection drive pattern of the coordinate detection drive channel.

[0086] It should be noted that for a computer to operate smoothly, there are strict requirements regarding the generation time, settling time, and cancellation time of various operation signals, as well as the relationships between them. Applying time-based control to operation signals is called timing control.

[0087] Furthermore, when the touch signal is emitted in the upper half of the screen, the processor MCU controls the drive control unit to drive the accelerated drive graphics of the upper half of the screen through the upper half screen acceleration drive channel; when the touch signal is emitted in the lower half of the screen, the processor MCU controls the drive control unit to drive the accelerated drive graphics of the lower half of the screen through the lower half screen acceleration drive channel; when the touch signal is emitted in the full screen, the processor MCU drives the control unit to drive the accelerated drive graphics of both the upper and lower half of the screen through the upper half screen acceleration drive channel and the lower half screen acceleration drive channel.

[0088] S56: The processor MCU generates coordinate instructions based on the coordinate detection drive graphic, the acceleration drive graphic, and the comparison signal;

[0089] Specifically, based on the coordinate detection channel and the acceleration driving graphics, the area occupied by the comparison signal on the screen is obtained; a preset point is selected from the area as a reference point; the coordinates of the corresponding instruction relative to the reference point are obtained, and a coordinate instruction is generated.

[0090] S57: The processor MCU sends the coordinate command to the whole machine through the communication port, and the whole machine responds based on the coordinate command.

[0091] Specifically, the coordinate command includes: the absolute coordinate value of the reference point and the relative coordinate of the touch signal with respect to the reference point.

[0092] It should be noted that the communication port uses a signal cable, which is plugged into the signal terminal of the whole machine to realize all the functions of the whole machine, and can be realized by touch on the display screen.

[0093] This invention also provides a control device. Figure 6 A schematic diagram of the control device in an embodiment of the present invention is shown. The control device includes:

[0094] Information acquisition module: When a user is detected operating the touch screen, the module acquires the touch signal of the user's touch operation on the touch screen and transmits the touch signal to the receiving sensor for preprocessing.

[0095] Processing module: Transmits the pre-processed touch signal to the receiving and processing unit. The receiving and processing unit processes the pre-processed touch signal to obtain the comparison signal and touch area information, and transmits the touch area information and the comparison signal to the processor MCU at the same time.

[0096] The processor MCU determines whether the touch signal is a valid touch based on the touch area information;

[0097] If valid, the processor MCU detects the position of the touch signal based on the comparison signal; the position of the touch signal includes: the upper half of the screen, the lower half of the screen, and the full screen;

[0098] Based on the position of the touch signal, obtain the coordinate detection driving graphic and the acceleration driving graphic corresponding to the touch signal, and transmit the coordinate detection driving graphic and the acceleration driving graphic to the processor MCU.

[0099] Working module: The processor MCU generates coordinate instructions based on the coordinate detection driving graphic, the acceleration driving graphic, and the comparison signal;

[0100] The processor MCU sends the coordinate command to the entire device through the communication port, and the entire device responds based on the coordinate command. This invention provides a control method and device for a touch panel. When a touch operation is performed, the acceleration driving graphic and coordinate detection driving graphic do not need to run in full screen. They can autonomously determine the location of the touch point and drive the acceleration driving graphic and coordinate detection driving graphic only by driving the acceleration driving channel and coordinate detection driving channel at that location. This achieves the purpose of accelerating area driving detection, thereby improving the driving cycle speed and increasing the writing response speed.
