[0002] To test the touch performance of a display module, it's necessary to display the trajectory of a touch swipe. Currently, this is done by displaying the touch trajectory on a touch testing screen of the display module testing equipment or on an external display. However, the resolution of these screens sometimes doesn't match the resolution of the display module, making it difficult to accurately judge the test results. Furthermore, the screen size differs from the display module size, making it difficult to see the effect of trajectory testing at the edges of the display module.

[0057] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0058] This embodiment provides a touch detection method for a display module. Based on this method, the touch test effect of the screen under test can be determined more intuitively. In specific application, this embodiment first acquires touch information on the display module and determines trajectory point data based on the touch information. Then, based on the trajectory point data, trajectory line data is generated, and image processing is performed on the trajectory line data to obtain display data corresponding to the trajectory line data.

This makes the screen for touch testing and the screen for displaying the touch trajectory the same screen, so as to intuitively reflect the touch test effect.

[0059] Exemplary methods

[0060] The touch detection method for the display module in this embodiment can be applied to a detection device, which can be a smart product terminal such as a computer, mobile phone, or tablet. In this embodiment, the detection device can implement the overall process of the touch detection method for the display module in this embodiment. Specifically, as shown... Figure 1 As shown, the touch detection method of the display module in this embodiment includes the following steps:

[0061] Step S100: Obtain touch information on the display module, and determine trajectory point data based on the touch information.

[0062] In this embodiment, when performing touch detection on the screen of the display module, the detection device first acquires touch information from the display module. This touch information is generated when a user touches or swipes on the screen of the display module using their finger or stylus. Then, the detection device can determine the trajectory point data corresponding to the touch based on this touch information. In this embodiment, the trajectory point data refers to the touch points left when a user touches the screen of the display module using their finger or stylus.

[0063] In one implementation, this embodiment includes the following steps when determining trajectory point data:

[0064] Step S101: Parse the touch information to obtain the coordinate information in the touch information, the coordinate information including the starting point coordinates and the ending point coordinates;

[0065] Step S102: Determine the trajectory point data based on the starting point coordinates and the ending point coordinates.

[0066] Specifically, after acquiring touch information, the detection device in this embodiment can parse the touch information to obtain the coordinate information corresponding to the touch information, which includes the starting point coordinates and the ending point coordinates. That is, when touching the screen of the display module, the coordinates of the touch start point and the touch end point can be obtained. Specifically, during testing, the display module and the detection device are connected, thus enabling data communication. Therefore, when a user touches the screen of the display module with their finger or stylus, the display module can monitor the entire touch event, especially the start and end of the touch event. Thus, the display module obtains the touch information, which may include the coordinates of the touch start point and the touch end point. The display module can send this touch information to the detection device, allowing the detection device to parse the touch information and obtain the starting point coordinates and the ending point coordinates (i.e., the coordinates of the touch start point and the touch end point).

[0067] Once the detection device obtains the starting and ending coordinates, it can determine the trajectory point data based on these coordinates. Since each touch and swipe by the user on the display module's screen is continuous (i.e., the finger or stylus does not leave the screen), there are several touch points between the starting and ending coordinates. In this embodiment, after obtaining the touch information, the detection device determines all touch points between the starting and ending coordinates based on the starting and ending coordinates. Each touch point corresponds to a single trajectory point; therefore, trajectory point data can be obtained based on these touch points.

[0068] Step S200: Based on the trajectory point data, generate trajectory line data, and perform image processing on the trajectory line data to obtain display data corresponding to the trajectory line data, wherein the display data is used to reflect the trajectory image corresponding to the trajectory line data.

[0069] Once the detection device obtains all the trajectory point data, this embodiment can connect these trajectory point data to form a trajectory line data, which is the touch trajectory of the user using a finger or stylus on the display module's screen. To display the user's touch trajectory as an image, the detection device in this embodiment can perform image processing on the trajectory line data to obtain the corresponding display data, which is the trajectory image corresponding to the trajectory line data.

[0070] In one implementation, this embodiment includes the following steps when determining the display data:

[0071] Step S201: Input the coordinate data corresponding to the trajectory line data into a preset image processing unit;

[0072] Step S202: Generate image data from the coordinate data using the image processing unit, and send the image data to the image compression unit;

[0073] Step S203: Compress the image data based on the image compression unit to obtain the display data.

[0074] Specifically, the trajectory line data in this embodiment is based on connecting several trajectory points, and each trajectory point has its own corresponding coordinate data. In order to generate the image corresponding to the trajectory line data, this embodiment can input the coordinate data corresponding to the trajectory line data into a preset image processing unit. The image processing unit can then sequentially annotate the coordinate data onto the image corresponding to the screen of the display module. Specifically, this embodiment can first acquire an image corresponding to the screen of the display module, which can be an image with a black background. Then, the coordinate data corresponding to the trajectory line data is sequentially annotated onto the image from the starting point coordinates to the ending point coordinates to obtain the image data. The detection device then inputs the image data with annotated coordinate data into an image compression unit. Based on this image compression unit, the image data is compressed. The purpose of the compression is to compress the coordinate data and the image itself to meet the requirements of image display, thus obtaining the corresponding display data, which is the trajectory image corresponding to the touch trajectory.

[0075] Step S300: Send the display data to the display module and control the display data to be displayed on the display module so that the display module can synchronously display the corresponding trajectory image when touched.

[0076] Once the display data is obtained, this embodiment can send the display data to the display module and control the screen of the display module to display the display data. In other words, this embodiment displays the touch trajectory generated by the touch test on the screen of the display module. This makes the screen for touch testing and the screen for displaying the touch trajectory the same screen, so as to intuitively reflect the touch test effect.

[0077] In one implementation, this embodiment includes the following steps when displaying display data:

[0078] Step S301: Obtain the screen size data of the display module;

[0079] Step S302: Obtain the trajectory size data of the trajectory image corresponding to the displayed data;

[0080] Step S303: Display the display data based on the screen size data and the trajectory size data.

[0081] Specifically, in order to achieve a better display effect when displaying display data, this embodiment first obtains the screen size data of the display module and the trajectory size data of the trajectory image corresponding to the display data. Since this embodiment needs to display the trajectory image corresponding to the display data on the screen of the display module, if the screen size data of the display module is too large than the trajectory size data, it will affect the display details and display effect. Therefore, this embodiment can determine the proportional relationship between the screen size data and the trajectory size data based on the screen size data and the trajectory size data. This proportional relationship reflects the difference between the screen size data and the trajectory size data. Specifically, in this embodiment, the screen size data is the size composed of the length and width of the screen, while the touch trajectory is a line segment. Therefore, the trajectory size data in this embodiment is the length and width of the touch trajectory. When calculating the proportional relationship, it can be calculated based on the length of the screen and the length of the touch trajectory, and the width of the screen and the width of the touch trajectory, respectively. After calculating the proportional relationship, this embodiment can scale the trajectory size data according to the proportional relationship. The purpose of the scaling is to better display the touch trajectory, so that the touch trajectory can be displayed completely and clearly on the screen of the display module. Specifically, in this embodiment, when scaling the trajectory size data, the length of the touch trajectory is the primary consideration. Scaling is first performed along the length direction, and then the width of the touch trajectory is increased to display more touch details and improve the display effect. Therefore, compared to existing technologies where the touch test screen and the screen displaying the touch trajectory are not on the same screen, this application displays the touch trajectory image on the same screen of the display module, ensuring that the touch test screen and the screen displaying the touch trajectory are on the same screen for better observation of the touch test effect.

[0082] Furthermore, in this embodiment, after displaying the data on the display module, test result information is output. This test result information is the data and parameter information of the touch test results. Therefore, this embodiment displays the test result information synchronously on one side of the display data, which allows testers to more intuitively understand the touch performance of the display module's screen. Of course, in other implementations, the test result information can also be displayed on an extended screen connected to the testing device; this embodiment is not limited to this.

[0083] In summary, this embodiment first acquires touch information from the display module and determines trajectory point data based on the touch information. Then, based on the trajectory point data, trajectory line data is generated, and image processing is performed on the trajectory line data to obtain display data corresponding to the trajectory line data. The display data reflects the trajectory image corresponding to the trajectory line data. Finally, the display data is sent to the display module, and the display module is controlled to display the display data, so that the display module synchronously displays the corresponding trajectory image when touched. In this embodiment, when performing touch testing on the display module's screen, trajectory line data is first generated, then the corresponding trajectory image is generated, and the trajectory image is displayed on the display module's own screen. This ensures that the screen used for touch testing and the screen displaying the touch trajectory are the same screen, allowing for a more intuitive reflection of the touch test results.
