Description

Background
Along with the application and development of the touch display, the touch control system of the touch display is increasingly used in various display products, the size of the products is increasingly large, and particularly, the application of the capacitive touch control system is more extensive, wherein the capacitive touch control system is applied to more display products including conference touch control whiteboards, interactive advertisement screens, interactive ordering machines, teaching touch control blackboards and the like. In the manufacturing process of the display product, the capacitive touch screen and the liquid crystal display screen are required to be closely attached. However, due to the oversized product, the display is deformed to a certain extent during production, product transportation, installation and erection, and long-time hanging, so that the distances between the liquid crystal display and the capacitive touch screen in different local areas of the display are changed in unequal amounts.
As can be seen, the capacitive touch screen detects the touch operation by the change of the capacitance sensing amount, however, when the display is deformed, the distance between each area of the liquid crystal display and the capacitive touch screen is not uniform, so that the capacitance sensing amount generated by the same touch operation in each area of the display is different, and thus each area of the display has different sensitivity, and a large difference exists between the sensitivities. When the various areas have different sensitivities, a series of derivative problems can be caused when a user operates the display, for example, suspension touch control problems when the sensitivity is too high can cause the display to be easily interfered and misjudge touch operation, and partial area touch operation of the display is not responded when the sensitivity is too low, so that the functions of a touch control system of the display are disabled, and the like.
Further, even though a manufacturer can perform various corrections on the touch control system in the production link of the display type product, the manufacturer is difficult to predict physical deformation generated in the processes of carrying, logistics, field erection and the like after the production of the product because the deformation belongs to a physical problem, so that correction parameters obtained by various corrections on the touch control system in the production link of the product cannot solve the problem generated by the physical deformation of the product.

Based on the hardware structure of the device, the embodiment of the touch system adapting method is provided.
Referring to fig. 2, in a first embodiment of the touch system adapting method of the present invention, the touch system adapting method includes:
step S10, obtaining deformation of a display, and determining a sensitivity distribution diagram of a touch system of the display according to the deformation;
The debugging method of the touch system is applied to the touch system of the touch display, and particularly is applied to the touch system of the capacitive touch display. The touch system adapting method is implemented in a touch system adapting device, which may be a personal computer or a terminal device with display and data processing functions, such as a tablet computer.
In this embodiment, the display is a capacitive touch display, and the touch system adapting method is used to adapt the sensitivity of the display. It is known that, for capacitive touch display products with larger sizes, such as a conference touch whiteboard, an interactive advertisement screen, a teaching touch blackboard, and the like, the display of the product is likely to deform during reproduction, transportation, installation and later use, and the sensitivity of the display is seriously affected when the deformation degree exceeds a certain threshold value. The touch system adapting method provided by the embodiment of the application can adapt the sensitivity of the capacitive touch display, so that the problem caused by deformation of the display is solved.
Specifically, firstly, the deformation amount of the display is obtained, and the sensitivity distribution diagram of the displayed touch system is determined according to the deformation amount of the display, and as can be seen, the capacitive touch display generally comprises a display screen and a capacitive touch screen, wherein the display screen comprises a liquid crystal display screen (hereinafter, the liquid crystal display screen is taken as an example for illustration), a capacitive sensor is arranged in the touch screen and is connected with the touch system of the display, and the touch system detects touch operation by using the capacitive sensor in the touch screen and generates an induction signal. Specifically, the touch system of the display detects a touch operation according to a change amount of a sensing capacitance of each capacitive sensor when the touch screen is touched, and the change amount of the sensing capacitance of the capacitive sensor is related to a distance between the touch screen and the liquid crystal display. In the use process of the display, different areas of the display may deform to different degrees due to long-term vertical placement or inclined suspension towards the ground, so that the distances between the touch screen and the liquid crystal display may be different in different areas of the display, and the sensitivity of the different areas of the display is different. According to the distances between the liquid crystal display screen and the touch screen in different areas of the display, the sensitivity distribution diagram of the touch system of the display can be determined.
Further, in step S10, the step of acquiring the deformation amount of the display includes:
step A1, acquiring node capacitances between each capacitive sensor in the touch screen and the display screen;
a2, determining a distance distribution diagram between the touch screen and the display screen according to the node capacitance;
and step A3, determining the deformation amount of the display according to the distance distribution diagram.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a touch screen and a liquid crystal display of a display, in fig. 3, there is a certain bonding distance between the touch screen and the liquid crystal display of the display, the bonding distance is uniform, after the display is deformed, the distance between the touch screen and the liquid crystal display may change, and in different areas of the display, the distance between the touch screen and the liquid crystal display may be different. When the distance between the liquid crystal display screen and the touch screen of the display is determined, the distance between each capacitive sensor in the touch screen and the display screen is obtained, and a distance distribution diagram between the touch screen and the liquid crystal display screen is obtained according to the distance between each capacitive sensor in the touch screen and the liquid crystal display screen, wherein the distance distribution diagram represents the distance relation between the liquid crystal display screen and the touch screen in different areas of the display. And determining the deformation amount of the display according to the distance distribution diagram between the touch screen and the liquid crystal display. For example, the deformation amount of the display is determined according to the difference between the maximum value and the minimum value of the distances in different areas in the distance distribution diagram of the display, and the deformation area of the display is further determined according to whether the distance distribution between the touch screen and the liquid crystal display is uniform in different areas of the display. The distance between each capacitive sensor of the touch screen and the liquid crystal display screen is determined according to the node capacitance corresponding to each capacitive sensor, referring to fig. 4, fig. 4 is a distribution diagram of the node capacitance corresponding to each capacitive sensor of the touch screen of the display, and the node capacitance of the capacitive sensor shown in fig. 4 is low in the middle and high in the periphery, and the node capacitance gradually increases from the middle to the periphery. The area in the left frame line in fig. 4 is an area with moderate sensitivity obtained by calculation according to the distribution of node capacitance, and can be used as a calibration area for adjusting the display. It is known that the capacitance of the capacitive sensor is related to the distance, and the larger the distance is, the smaller the capacitance is, and the largest distance between the touch screen and the liquid crystal display screen is, and the most serious deformation degree is. According to the node capacitance corresponding to each capacitive sensor on the touch screen, the distance between the touch screen and the liquid crystal display in different areas of the display can be determined, so that the deformation amount of the display is determined.
Further, in step S10, the step of determining a sensitivity distribution map of the touch system of the display according to the deformation amount of the display includes:
and B1, dividing the area of the display according to the deformation amount to obtain a sensitivity distribution diagram of a touch control system of the display, wherein the sensitivity distribution diagram corresponds to the induction capacitance variation amount of each capacitance sensor when the touch operation is generated on the touch screen, and the touch control system of the display outputs induction signals according to the induction capacitance variation amount to respond to the touch operation generated on the touch screen.
As can be seen, the sensitivity distribution diagram of the display characterizes the sensitivity distribution of different areas of the display, and the sensitivity of the display corresponds to the change of the sensing capacitance of each capacitive sensor when the touch operation is generated on the touch screen. Therefore, the touch system is determined by each capacitive sensor of the touch screen according to the sensing signal output by the touch operation, and the sensing capacitance variation generated by the touch operation is related to the distance between the touch screen and the liquid crystal display screen. Therefore, when a touch operation is detected, the sensing capacitance variation of the capacitive sensor of the touch screen can be determined by the sensing signal output by the touch system, otherwise, the distance between the touch screen and the liquid crystal display can be determined according to the node capacitance of each capacitive sensor of the touch screen, so that the sensing capacitance variation of each capacitive sensor according to the touch operation and the sensing signal output by the touch system according to the touch operation, namely the sensitivity of the display can be determined.
When determining the sensitivity distribution diagram of the display according to the deformation amount of the display, specifically, referring to fig. 5, fig. 5 is a schematic diagram of the sensitivity distribution diagram of the display, when determining the sensitivity distribution diagram of the display, determining the deformation amount of the display according to the node capacitance distribution diagram of the capacitance sensor shown in fig. 4, wherein the sensitivity of the display is related to the deformation amount, and dividing the display into different sensitivity areas corresponding to different deformation degrees according to the deformation amount of the display and referring to the sensitivity of the calibration area, so as to obtain the sensitivity distribution diagram of the touch control system of the display shown in fig. 5. In fig. 5, the region one, the region two and the region three represent regions having different sensitivities, and the sensitivities in the same region are not greatly different or are the same.
And step S20, determining a correction parameter according to the sensitivity distribution diagram, and adapting the sensitivity of the touch control system of the display according to the correction parameter.
And determining correction parameters for adjusting the display according to a sensitivity distribution diagram of the display, wherein the sensitivity of the display is determined according to a touch screen, and when a user touches the display, a touch system of the display senses touch operation of the user through the touch screen, the sensing capacitance of each capacitance sensor changes, and the touch system detects the capacitance change of the capacitance sensor, so that the output sensing signal is changed. When the sensing signal output by the touch control system exceeds a certain threshold, a touch operation instruction is triggered, and the touch operation of a user is responded. When the sensitivity of the display changes due to deformation, if the threshold of the sensing signal of the touch control system for triggering the touch operation instruction according to the touch operation of the user is not changed, the problem of abnormal sensitivity can occur. For example, when the distance between the touch screen of the display and the liquid crystal display increases, after the user touches the display, the capacitance variation of the point capacitance sensor of the touch screen will decrease, and the sensing signal output by the touch system according to the touch operation of the user will also decrease. Or when the distance between the touch screen and the liquid crystal display screen of the display is reduced, the sensing signal output by the touch system according to the touch operation of the user is increased, if the threshold value of the sensing signal of the touch operation instruction triggered by the touch system is not adjusted, the sensing signal output by the touch system according to the touch operation of the user is larger than the threshold value, so that the sensitivity of the display is overhigh, thereby causing suspended touch and causing misoperation, and bad user experience. Therefore, when the display deforms and the deformation amount reaches a certain degree, the sensitivity of the display needs to be adjusted, so that the user experience is improved.
Specifically, the sensitivity of different areas of the display needs to be determined according to the sensitivity distribution diagram of the display, then the sensitivity correction parameters of the different areas of the display are determined, and the sensitivity of the different areas of the display is adapted according to the sensitivity correction parameters of the different areas of the display. The sensitivity of the different sensitivity regions of the display after the adjustment may be different, and in the sensitivity distribution diagram, the sensitivity of the regions with the same sensitivity after the adjustment is not necessarily the same. This is because, in the sensitivity distribution diagram, there is a boundary region between regions having the same sensitivity, and the sensitivity of the boundary region needs to be simultaneously referred to the sensitivity correction parameters of different sensitivity regions, so as to ensure that the effects of the sensitivities of the different regions of the display after the adjustment are consistent at the user operation end, and the "jump" sense of inconsistent touch sensitivity of the different regions of the same display will not occur.
Further, in step S20, the step of determining the correction parameter according to the sensitivity distribution diagram of the touch system of the display includes:
step C1, acquiring preset sensitivity of the display, and determining preset induction capacitance variation of each capacitance sensor in the touch screen corresponding to the preset sensitivity;
And C2, converting the preset induction capacitance variation according to the sensitivity distribution diagram to obtain correction parameters.
When the sensitivity correction parameters are determined, the preset sensitivity of the display is required to be obtained first, and then, in the touch screen of the display, the touch screen of the display is determined according to the preset sensitivity of the display, when the touch system triggers a touch operation instruction according to touch operation, each capacitive sensor corresponds to a sensing capacitance change amount, namely, a triggering threshold value of the sensing capacitance change amount corresponding to the preset sensitivity. Based on the trigger threshold of the capacitive sensor and the sensitivity distribution conditions of different areas after the display is deformed, the trigger threshold of the sensing capacitance change amount when the touch control system triggers a touch operation instruction according to touch operation is corrected, so that correction parameters are obtained. The correction parameter characterizes a specific value of the corresponding trigger threshold value and the specific value of the corresponding trigger threshold value when the touch control system triggers the touch operation instruction according to the touch operation, so that the sensitivity of the touch control system of the display is adjusted to be within a moderate range value. For example, when a touch operation is performed on a point of the third area shown in fig. 5, the amount of change in the sensing capacitance corresponding to the sensing signal output from the touch system is detected as E, whereas when a touch operation is performed on a point of the first area shown in fig. 5, the same distance as D from the point of the first area is detected as E/2, the sensitivity of the first area is considered to be different from that of the third area. However, the preset sensitivities of the displays are the same, and for the deformed displays, the same touch operation is performed at different positions, so that a touch operation instruction may be triggered or not triggered, thereby causing the sensitivity abnormality of the touch control system. Therefore, correction needs to be performed on different areas of the display according to the correction parameters, for example, when the trigger threshold of the position a is set to be E/2, the trigger threshold of the position B is set to be E/4, and when the capacitance induction variation corresponding to the induction signal output by the touch control system according to the touch operation is greater than or equal to the corrected trigger threshold, the touch operation instruction is triggered, the effect on the touch operation performed by the user in different sensitivity areas is the same, and the sensitivity experience of the user operation end is improved.
In this embodiment, by acquiring a deformation amount of a display, determining a sensitivity distribution diagram of a touch system of the display according to the deformation amount; and determining a correction parameter according to the sensitivity distribution diagram, and adapting the sensitivity of the touch control system of the display according to the correction parameter. When the display is deformed, the sensitivity of the touch control system of the display is adjusted according to the deformation amount of the display, the sensitivity of the touch control system of the display is adjusted to a proper value, the problem that the sensitivity of the touch control system of the display is abnormal due to the physical deformation of the display is solved, and the user experience is improved.
Further, on the basis of the above embodiment of the present invention, a second embodiment of the touch system adapting method of the present invention is provided.
