Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to an optimization method for a touch display screen integrating On-cell technology and a touch display screen. Background Art

[0002] Currently, there are mainly two technical routes for touch display screens, namely In-cell and On-cell. In-cell refers to the method of embedding the touch panel function into the liquid crystal pixels, and On-cell refers to the method of embedding the touch panel function between the color filter substrate and the polarizer.

[0003] The In-Cell technology reduces signal interference and transmission loss through deep integration of the touch control and display functions, thereby achieving higher sensitivity; while the On-Cell technology has relatively low sensitivity due to the influence of structural separation and external interference. Although the In-Cell technology has advantages in technical indicators, it has disadvantages in terms of manufacturing cost, structural complexity, and yield rate.

[0004] However, since the On-Cell technology is implemented in a way similar to an external attachment, there is a certain disadvantage in the accuracy of touch control, and further research is needed on how to improve the accuracy of touch control. Summary of the Invention

[0064] To understand the technical solutions in this application more clearly, the related technologies will be introduced first.

[0065] Please refer to Figure 1 , it can be seen from the content limited in the figure that the In-cell technology places the ITO touch film under the upper glass substrate of the display panel and integrates it with the liquid crystal layer. This technology not only has higher precision but also eliminates the need for a touch panel, making the entire screen thinner and lighter.

[0066] The On-cell technology integrates the touch sensor between the color filter substrate and the polarizer. This technology has relatively lower difficulty, but compared with the In-cell technology, its precision and sensitivity may be reduced.

[0067] The touch detection methods used in In-cell touch display screens and On-cell touch display screens are self-capacitance detection method and mutual-capacitance detection method. The self-capacitance detection method measures the capacitance of a single electrode to the ground. When touched, the human body capacitance is superimposed on the electrode capacitance, resulting in an increase in the total capacitance. After scanning the X and Y axis electrodes, the combined coordinates are obtained; the mutual-capacitance detection method detects the coupling capacitance at the intersection of rows and columns. When touched, the coupling capacitance decreases. By scanning all intersections in the way of row-by-row excitation and column-by-column signal reception, the coordinates of each touch point are accurately calculated.

[0068] The self - capacitance detection method is vulnerable to environmental noise (such as electromagnetic interference), while the mutual - capacitance detection method can filter out some noise through row - column intersection detection. However, the self - capacitance detection method has ghost points, and the mutual - capacitance detection method has problems such as high energy consumption and low scanning efficiency.

[0069] The following further elaborates on the technical solutions in this application in conjunction with the accompanying drawings.

[0070] Please refer to Figure 2 , the optimization method of the touch display screen integrating On - cell technology disclosed in this application is applied to the touch display screen integrating On - cell technology. Such a touch display screen is obtained by superimposing a touch film on a display panel to get a touch display screen (On - cell finished product).

[0071] This application discloses an optimization method of a touch display screen integrating On - cell technology. Please refer to Figure 3 , in some examples, the optimization method of the touch display screen integrating On - cell technology disclosed in this application includes the following steps:

[0072] S101, scan the display area using the row - column independent scanning method to obtain multiple suspected position points;

[0073] S102, scan the area where the suspected position points are located using the row - column response scanning method and screen according to the scanning results to obtain real position points;

[0074] S103, use the row - column independent scanning method to determine the edge area of the real position points, draw the contour of the edge area, and calculate the central position point of the contour of the edge area;

[0075] S104, establish a scanning range based on the central position point and use the row - column response scanning method within the scanning range to track the movement of the real position points;

[0076] Among them, during the tracking process, the central position point of the contour of the edge area is dynamically updated.

[0077] Overall, the optimization method of this application mainly optimizes the touch recognition accuracy of the touch display screen integrating On - cell technology. The specific method is achieved by combining the row - column independent scanning method and the row - column response scanning method and coordinating with the corresponding data processing process.

[0078] In step S101, first scan the display area using the row - column independent scanning method. After scanning, suspected position points are obtained. Here, the row - column independent scanning method refers to scanning using the self - capacitance method, such as Figure 4As shown, suspected position points will be obtained at this time. There are two types of suspected position points, namely real position points and ghost points. Of course, here, multi-point operations need to be performed in the display area.

[0079] When there is only one suspected position point in the display area, the row-column independent scanning method is continuously used to scan the display area.

[0080] Then, in step S102, the row-column response scanning method is used to scan the area where the suspected position point is located and filter according to the scanning results. The row-column response scanning method here refers to using the mutual capacitance method for scanning. This method can eliminate ghost points and obtain real position points.

[0081] In this step, only the row-column response scanning method is used to scan the area where the suspected position point is located instead of the entire display area. The advantage of this method is that it greatly reduces the scanning range of the row-column response scanning method, and has better advantages in terms of scanning speed and energy consumption, and can obtain better response speed and lower power consumption.

[0082] In step S103, the row-column independent scanning method is used to determine the edge area of the real position point and draw the contour of the edge area ( Figure 5 as shown) and calculate the central position point of the contour of the edge area. The function of this step is to achieve fast tracking of the real position point. Because the ghost points have been eliminated in the previous steps, the row-column independent scanning method can be used to determine the edge area of the real position point for drawing.

[0083] Finally, in step S104, a scanning range is established based on the central position point, and the row-column response scanning method is used to track the movement of the real position point within the scanning range. The reason for using the row-column response scanning method here is that the row-column response scanning method has a faster response speed.

[0084] At the same time, it is also required to dynamically update the central position point of the contour of the edge area during the tracking process. During the dynamic update of the central position point, the scanning range coordinated with the central position point will also be dynamically updated. In actual application scenarios, the scanning range can be made to fit better with the object in contact with the display area, which is convenient for achieving fast response to the movement of the object.

[0085] In some examples, the specific method for calculating the central position point of the contour of the edge area is as follows:

[0086] S201, randomly select multiple edge points on the contour of the edge area, and the shortest straight-line distance between adjacent edge points is equal;

[0087] S202, use two adjacent edge points to establish the first line segment;

[0088] S203. Create a second line segment based on the first line segment, where the second line segment is perpendicular to the first line segment and passes through the midpoint of the first line segment;

[0089] S204. Obtain the convergence point or convergence area of the second line segment;

[0090] S205. Use the convergence point of the second line segment as the central position point of the edge area contour or the central point of the convergence area of the second line segment as the central position point of the edge area contour.

[0091] Please refer to Figure 6 , in steps S201 to S205, use the first line segments connected end to end to create a second line segment perpendicular to the midpoint of the first line segment, and then obtain the convergence point or convergence area. Of course, here, the probability of obtaining the convergence point is very small, and generally the convergence area is obtained.

[0092] For example, in Figure 6 , the obtained convergence area is a shape similar to a triangle. At this time, the centroid of the triangle (dashed area) can be used as the center of the convergence area. When the initially obtained convergence area is an irregular shape, it is necessary to continue to use the above method to narrow the convergence area and appropriately increase the length of the first line segment.

[0093] This is a processing method similar to approximation, which can obtain a relatively accurate central position point of the edge area contour.

[0094] The specific method for establishing the scanning range based on the central position point is as follows:

[0095] Create a scanning circle with the central position point as the center, and the edge area contour is located inside the scanning circle;

[0096] Select multiple areas on the scanning circle as the scanning range;

[0097] Among them, the number of scanning circles is multiple, and in the direction away from the central position point, the diameter of the scanning circle tends to increase;

[0098] There is a blank area between adjacent scanning circles;

[0099] The connection line of any two scanning ranges located on two adjacent scanning circles does not pass through the central position point.

[0100] In the above method, please refer to Figure 7 , multiple scanning ranges will be placed around the edge area contour, and the role of these scanning ranges is to predict the movement of the edge area contour. The scanning ranges are divided into multiple groups, and each group of scanning ranges is on the same scanning circle (dashed line).

[0101] In some examples, when scanning a scanning range, the following content is included:

[0102] Use the row-column independent scanning method to scan the display area to obtain a suspected used scanning range;

[0103] Use the row-column response scanning method to screen the obtained suspected used scanning range to obtain the actual used scanning range;

[0104] Create a moving trajectory of the edge region contour based on the obtained multiple actual used scanning ranges, including speed and direction.

[0105] In the above method, the row-column independent scanning method and the row-column response scanning method are also used to screen the scanning range. This part of the content is the same as the content of removing ghost points and will not be elaborated here. Here, it can be regarded that the scanning range is triggered, and through the triggered scanning range, the moving trajectory of the edge region contour can be conveniently obtained.

[0106] Furthermore, it is also necessary to move the scanning range according to the moving trajectory of the edge region contour. The purpose of moving the scanning range is to enable the scanning range to synchronously track the movement of the edge region contour.

[0107] In some possible implementation manners, during the movement of the scanning range, the diameter of the scanning circle needs to be increased, and the increase amount of the diameter of the scanning circle is positively correlated with the speed of the moving trajectory of the edge region contour. The purpose of increasing the diameter of the scanning circle is considered that the movement of the edge region contour may break through the limitation of the scanning range, and appropriately increasing the diameter of the scanning circle can avoid the occurrence of the above situation.

[0108] In some examples, the following content is also added:

[0109] S301, obtain the parameters of the area inside the edge region contour on the display area;

[0110] S302, compare the parameters with the parameter model to determine the contact area medium;

[0111] S303, when the contact area medium includes a water medium, calculate the center position point of the edge region contour and randomly select multiple auxiliary center position points on the edge region contour;

[0112] Among them, the center position point and the auxiliary center position points are processed in the same way.

[0113] The content in steps S301 to S303 is to cope with the influence of water operation on the display area. The specific processing process is to obtain the parameters of the area inside the edge region contour on the display area, and then compare the parameters with the parameter model to determine the contact area medium.

[0114] The parameter in the inner area of the edge area contour here refers to the change amount of the capacitance value of this area, and this change amount of the capacitance value is composed of multiple point data. When the finger carries water, the change amount of the capacitance value in this area will change. By comparing the actual value with the parameter model obtained through statistics, the medium of the contact area can be determined.

[0115] When the medium of the contact area includes a water medium, calculate the central position point of the edge area contour and randomly select multiple auxiliary central position points on the edge area contour. The role of the auxiliary central position points is to track the remaining water medium.

[0116] The specific method is as follows:

[0117] When the central position point is in a moving state but the auxiliary central position point is in a static state, time the auxiliary central position point in the static state to obtain the static time;

[0118] When the static time is equal to the set reference time, perform a shielding process on the auxiliary central position point in the static state;

[0119] Obtain the parameter of the area where the auxiliary central position point in the static state is located and create a corresponding correction area in the shielding layer.

[0120] For the auxiliary central position point, adopt the method of accumulating the static time for processing. When the static time is equal to the set reference time, perform a shielding process on the auxiliary central position point in the static state. The specific method of the shielding process is to obtain the parameter of the area where the auxiliary central position point in the static state is located and create a corresponding correction area in the shielding layer.

[0126] Among them, during the tracking process, the central position point of the edge region contour is dynamically updated.

[0127] Furthermore, calculating the central position point of the edge region contour includes:

[0128] Randomly select multiple edge points on the edge region contour, and the shortest straight-line distance between adjacent edge points is equal;

[0129] Use two adjacent edge points to establish a first line segment;

[0130] Based on the first line segment, create a second line segment, which is perpendicular to the first line segment and passes through the midpoint of the first line segment;

[0132] Use the convergence point of the second line segment as the central position point of the edge region contour or the central point of the convergence region of the second line segment as the central position point of the edge region contour.

[0133] Furthermore, establishing a scanning range based on the central position point includes:

[0134] Create a scanning circle with the central position point as the center, and the edge region contour is located inside the scanning circle;

[0135] Select multiple regions on the scanning circle as the scanning range;

[0136] Among them, the number of scanning circles is multiple, and in the direction away from the central position point, the diameter of the scanning circle tends to increase;

[0137] There is a blank area between adjacent scanning circles;

[0138] The connection line of any two scanning ranges located on two adjacent scanning circles does not pass through the central position point.

[0139] Furthermore, when scanning the scanning range, it includes:

[0140] Use the row-column separate scanning method to scan the display area to obtain a suspected usage scanning range;

[0141] Use the row-column response scanning method to screen the obtained suspected usage scanning range to obtain a true usage scanning range;

[0142] Based on the obtained multiple true usage scanning ranges, create a movement trajectory of the edge region contour, including speed and direction.

[0143] Furthermore, it also includes moving the scanning range according to the movement trajectory of the edge region contour;

[0144] During the movement of the scanning range, the diameter of the scanned circle increases;

[0145] The increase in the diameter of the scanned circle is positively correlated with the speed of the movement trajectory of the contour of the edge region.

[0146] Furthermore, it also includes:

[0147] Obtain the parameters of the area inside the contour of the edge region on the display area;

[0148] Compare the parameters with the parameter model to determine the medium of the contact area;
