Description

[0001] This application is a divisional application of Chinese invention patent application (application number: 201910392905.0, application date: May 13, 2019, invention title: apparatus and method for driving a touch display panel). Technical Field

[0002] The present invention relates to an apparatus and method for driving a touch display panel. Background Technology

[0003] In related technologies, touch sensors are integrated into the display panel to form a touch display panel, enabling the touch display panel to have both display and touch sensing functions. Corresponding to the touch display panel, a touch controller and / or timing controller can be configured to the display driver. For example, a combined integrated circuit chip (TDDI IC) can drive the touch display panel to perform display and touch sensing functions.

[0004] For medium / large panels, at least two TDDI ICs may be required to drive the touch display panel to display images and sense touch events. The touch display panel is divided into multiple touch areas. Because different touch areas have different edge conditions, each TDDI IC is configured to process touch information for its corresponding touch area using different parameters and / or program code. Touch information processing is complex due to the varying edge conditions. Furthermore, when sensing touch events, each TDDI IC may only sense the corresponding touch area of ​​the touch display panel. In some cases, the TDDI IC may incorrectly sense touch events at the edge areas between different touch areas. Summary of the Invention

[0062] Figure 1 A schematic diagram of a device for driving a touch display panel according to an embodiment of the present invention is shown. (Reference) Figure 1 The device 100A is configured to drive the touch display panel 900 to perform display and touch sensing functions. The touch display panel 900 includes multiple data lines DL1 and DL2, and multiple sensing lines SL1 and SL2. For simplicity, Figure 1Only two data lines DL1 and DL2 and two sensing lines SL1 and SL2 are shown, and the invention is not limited thereto. Device 100A includes a first device 110, a second device 120, and a touch controller 130. Touch display panel 900 includes an active area AA, which is divided into two touch display areas AA1 and touch display area AA2. The first device 110 is configured to drive touch display area AA1 to perform display and touch sensing functions. The second device 120 is configured to drive touch display area AA2 to perform display and touch sensing functions.

[0063] The number of the first device 110, the second device 120, and the divided touch display areas AA1 and AA2 is not intended to limit the invention. In other embodiments, the device 100A may include more than two means for driving the touch display panel 900 to perform display functions and touch sensing functions, and the active area AA of the touch display panel 900 may also be divided into more than two touch display areas.

[0064] The first device 110 includes a timing controller 112, multiple display driving channels 114, and multiple touch sensing channels 116. For simplicity, Figure 1 Only one display driving channel 114 and one touch sensing channel 116 are shown, and the invention is not limited thereto. A timing controller 112 is coupled to the display driving channel 114. The timing controller 112 includes a data segmentation circuit 113. The data segmentation circuit 113 receives image data from the display interface (IF) and performs a data segmentation operation to obtain first image data from the image data. The timing controller 112 outputs the first image data to the display driving channel 114. The display driving channel 114 is coupled to a data line DL1 (i.e., the first portion of the data line DL) of the touch display area AA1. The display driving channel 114 drives the first image data to the data line DL1. Each of the display driving channels 114 includes, for example, an output buffer for driving the first image data to the corresponding data line DL1. The first image data acts as a source output SO and is output to the data line DL1.

[0065] When a touch event occurs in the touch display area AA1, first touch information can be transmitted via the sensing line SL1 (i.e., the first portion of the sensing line). The first touch information acts as a touch output TO and is input to the touch sensing channel 116 of the first device 110. The touch sensing channel 116 is coupled to the sensing line SL1 to sense the sensing line SL1. Each of the touch sensing channels 116 includes, for example, a connection switch MUX and a front-end circuit ADC to receive the first touch information from the touch display area AA1.

[0066] The second device 120 includes a timing controller 122, multiple display driving channels 124, and multiple touch sensing channels 126. For simplicity, Figure 1 Only one display driving channel 124 and one touch sensing channel 126 are shown, and the invention is not limited thereto. A timing controller 122 is coupled to the display driving channel 124. The timing controller 122 includes a data segmentation circuit 123. The data segmentation circuit 123 receives image data from the display interface and performs a data segmentation operation to obtain second image data from the image data. The timing controller 122 outputs the second image data to the display driving channel 124. The display driving channel 124 is coupled to a data line DL2 (i.e., the second portion of data line DL) of the touch display area AA2. The display driving channel 124 drives the second image data to data line DL2. Each of the display driving channels 124 includes, for example, an output buffer for driving the second image data to the corresponding data line DL2. The second image data acts as a source output SO and is output to data line DL2. In this embodiment, the first image data and the second image data may be a first / second portion of an image frame, or may come from different image frames.

[0067] When a touch event occurs in the touch display area AA2, second touch information can be transmitted via the sensing line SL2 (i.e., the second portion of the sensing line). The second touch information acts as a touch output TO and is input to the touch sensing channel 126 of the second device 120. The touch sensing channel 126 is coupled to the sensing line SL2 to sense the sensing line SL2. Each of the touch sensing channels 126 includes, for example, a connection switch MUX and a front-end circuit ADC to receive the second touch information from the touch display area AA2.

[0068] Touch controller 130 is configured to receive corresponding touch information from first device 110 and second device 120. In this embodiment, touch controller 130 is disposed outside touch display panel 900. Touch controller 130 includes storage device 132 for storing touch information, such as flash memory. The corresponding touch information includes first touch information corresponding to sensing line SL1 and second touch information corresponding to sensing line SL2. Touch controller 130 is further configured to determine touch events of touch display panel 900 based on the first touch information and the second touch information.

[0069] In this embodiment, both the first touch information from the first device 110 and the second touch information from the second device 120 are sent to the touch controller 130. The touch controller 130 analyzes and processes the first and second touch information, and thus can treat the touch display areas AA1 and AA2 as a whole to determine the touch event. Therefore, even if the touch event occurs at the edge areas R1 and L2 of the touch display areas AA1 and AA2, the touch controller can correctly determine the touch event of the touch display panel 900 based on the first and second touch information.

[0070] For example, the first device 110 and the second device 120 may be touch and display driver integrated circuit chips (TDDI ICs). The first device 110 and the second device 120 may be implemented with different integrated circuit chips. In this embodiment, the first device 110 is implemented with a first integrated circuit chip IC1, the touch controller 130 is implemented with a second integrated circuit chip IC2 (e.g., a touch integrated circuit (TIC)), and the second device 120 is implemented with a third integrated circuit chip IC3.
