The host can receive the touch signal from the touch driving circuit, determine a touch area, output an instruction to the timing controller through the system processing circuit, and control the source driver to drive the touch display panel to display an image in the touch area by the timing controller. In the process, the touch control and display functions depend on the processing of the host, and the touch control display device only plays a role in transmitting signals and executing host instructions. Therefore, when the touch display device is used, an external host and a system processing circuit are required, so that the whole structure is complex and the cost is high.

As shown in fig. 1, the touch display device includes a touch display panel 1, a touch driving circuit 2, a source driver 3 and a timing controller 4, wherein:

As shown in fig. 1, the touch driving circuit 2 is connected to the touch display panel 1, and is configured to respond to the first touch signal to generate first touch position information of the touch area. The first touch position information may include coordinates of the touch area in a predetermined coordinate system, and the number of the coordinates is not limited to one, and may be multiple, that is, the first touch position information reflecting the position of the touch area may be formed by multiple coordinates. The structure of the touch driving circuit 2 is specifically limited herein.
As shown in fig. 1, the source driver 3 is connected to the touch driving circuit 2, and is capable of receiving the first touch position information and sending the first touch position information to the timing controller 4. Meanwhile, the source driver 3 can drive the target pixel to display a base image according to a base image signal sent by the timing controller 4 based on the first touch position information of the target pixel, and the color, pattern, etc. of the base image are not particularly limited herein.
In one embodiment, as shown in fig. 2, the source driver 3 may include an output unit 31, wherein:
the output unit 31 is configured to output a driving signal to the touch display panel 1 in response to the base image signal, so that the target pixel displays the base image.
The base image signal may be generated by the timing controller 4 according to the first touch position information forwarded by the source driver 3, and the output unit 31 may generate a driving signal in response to the base image signal, the driving signal may drive the touch display panel 1 to display the base image.
In addition, in an embodiment, the source driver 3 may further include a storage unit 32, and the storage unit 32 may be connected to the timing controller 4, and is configured to store position information of each pixel of the touch display panel 1 and feed back the position information to the timing controller 4.
As shown in fig. 1, the timing controller 4 is connected to the source driver 3, and can receive the first touch position information forwarded by the source driver 3, such as the coordinates of the target pixel, and generate a base image signal according to the first touch position information, and the source driver 3 can generate a driving signal for driving the target pixel to display the base image according to the base image signal. The timing controller 4 generates a basic image signal according to the first touch position information according to a pre-written rule, so that different basic images can be formed along with the change of the touch area.
In one embodiment, as shown in fig. 3, the timing controller 4 includes a driving unit 41 simultaneously connected to the output unit 31 of the source driver 3, and the driving unit 41 can receive an image signal of a base image generated to the first touch position information to control the touch display panel 1 to display the base image through the output unit 31.
In addition, in an embodiment, the touch display panel 1 is further configured to generate a second touch signal in response to a second touch operation, where the second touch operation is different from the first touch operation, for example, the first touch operation is a click operation, and the second touch operation is a long press operation, which is not particularly limited herein. Whether the touch duration exceeds a threshold value or not in the click operation and the long-time press operation is the standard, and specific numerical values of the threshold value may be 1S, 2S, and the like, which is not particularly limited herein.
The touch driving circuit 2 is further configured to generate second touch position information in response to the second touch signal, where the second touch position information may also include coordinates in a predetermined coordinate system, but is not necessarily the same as the first touch position information.
The source driver 3 may forward the second touch signal to the timing controller 4, and the timing controller 4 is configured to compare the second touch position information with the first touch position information, and when the second touch position information is the same as the first touch position information and the gray scale adjustment information is received, the source driver may be controlled to drive the target pixel to display the target image according to the gray scale adjustment information, for example, adjust the gray scale of the base image, so as to obtain the target image. Meanwhile, when the gradation adjustment information is not received, the timing controller 4 may directly take the base image as the target image without adjustment.
The following is an exemplary description of the reception of the gradation adjustment information:
in one embodiment, the timing controller 4 may control the source driver 3 to drive the touch display panel 1 to generate an interactive interface when the second touch position information is the same as the first touch position information, and the specific shape and pattern of the interactive interface are not particularly limited herein, and are used for inputting gray scale adjustment information to adjust the base image to obtain the target image. For example, the interactive interface may be a window for adjusting gray levels, which may include a plurality of button patterns for operation, and the principle of touch operation through the interactive interface is not described in detail herein.
In another embodiment, as shown in fig. 4, the touch display panel 1 can be used to generate the second touch signal in response to a second touch operation of a touch device 7, and the touch device 7 can be used to input the grayscale adjustment information. The touch device 7 may be a touch pen, for example, an electronic color matching pen, and the color matching pen is provided with an operating mechanism such as a button or a switch for adjusting gray scale, so as to input gray scale adjustment information through the electronic color matching pen, adjust the basic image, and obtain the target image.
The first touch position information and the second touch position information are both sent to the timing controller 4 by the touch driving circuit 2 through the source driver 3, so that a line connecting the source driver 3 and the timing controller 4 can be utilized to avoid adding a line, for example, a stylus can be directly connected with an interface of the touch driving circuit 2, and a signal sent by the stylus can be sent to the timing controller 4 by the touch driving circuit 2 through the source driver 3. Of course, the signal may be directly transmitted to the timing controller 4 through wired or wireless communication without passing through the touch driving circuit 2 and the source driver 3, but a special wireless communication module or circuit needs to be provided.
Further, the source driver 3 of the touch display device of the present disclosure may further include a storage unit 32, which may be used to establish and store a corresponding relationship between the target pixel and the corresponding target image, so as to reproduce the target image by invoking the corresponding relationship, and avoid performing the first touch operation and the second touch operation again. Meanwhile, the source driver 3 may also feed back the aforementioned corresponding relation stored by the storage unit 32 to the timing controller 4.
Further, as shown in fig. 2, the timing controller 4 may further include a communication unit 42 connected to the storage unit 32, for outputting the correspondence relationship between the target pixel and the corresponding target image to the system processing circuit 5 in response to a call instruction of the system processing circuit 5(SOC), and the system processing circuit 5 may be connected to a host 6, and may feed back the correspondence relationship to the host 6, so as to be connectable to different system processing circuits 5. Further, the host 6 can also drive the touch display panel 1 to display images through the system processing circuit 5, the timing controller 4 and the source driver 3 according to the first touch position information and the second touch position information output by the touch driving circuit 2, so as to display complex images by using the data processing capability of the host 6.
In the touch display device of the present disclosure, the touch display panel 1 is not limited to one pixel distribution, and the touch driving circuit 2 and the source driver 3 can be connected to the touch display panel 1 with multiple pixel distribution, i.e. the multiple touch display panels 1 can be replaced with each other. Since the timing controller 4 stores the correspondence between the target pixels and the corresponding target images in one driving mode, the correspondence can be switched to another driving mode by a predetermined switching rule, so that the same images can be displayed. In this process, the source data of the touch display device, i.e. the corresponding relationship, is prevented from being directly changed by the control of the host 6. When the host 6 is connected externally, the timing controller 4 can communicate with the host 6 through a communication protocol such as a handshake protocol, so as to modify the source data of the touch display device.
For example, referring to fig. 5 and 6, each of fig. 5 and 6 exemplarily shows that each sub-pixel for displaying a target image includes n rows and m columns of sub-pixels, the color of the sub-pixel includes three colors of red (R), green (G) and blue (B), the color of the sub-pixel in the same column is the same, and the color of the sub-pixel in two adjacent columns is different, one pixel may include three sub-pixels with different colors, and the manner of forming the pixel by the sub-pixels in fig. 5 and 6 is different, that is, the driving mode is different. Meanwhile, fig. 5 and 6 also show the gray scale of each sub-pixel, for example, L127, i.e., the gray scale of the sub-pixel is 127.
Referring to fig. 5, fig. 5 shows m channels in a first driving mode, wherein the S1 direction shows the direction of each channel selection sub-pixel, thereby determining the sub-pixels driven by each channel.
As shown in fig. 6, m channels in the second driving mode are shown in fig. 6, wherein the S2 direction shows the direction of each channel selection sub-pixel, thereby determining the sub-pixels driven by each channel.
In the case where the driving mode is known, the target image displayed in the first driving mode can be reproduced in the second driving mode without performing the touch operation again by the predetermined conversion rule of the pixels of the first driving mode and the second driving mode.
In addition, as shown in fig. 7, since the corresponding relationship between the target pixel and the corresponding target image is stored, the target image of 8 bits can be converted into the target image of 10 bits by the preset conversion relationship between the image of 8 bits and the image of 10 bits, thereby avoiding the touch operation from being performed again. Further, the gray scale of the converted 10Bit target image can be finely adjusted, wherein the process I in fig. 7 is to convert the 8Bit target image into the 10Bit target image, and the process II is to finely adjust the gray scale of the 10Bit target image.
The present disclosure also provides a driving method of a touch display device, which can be the touch display device of the above embodiments, and the structure of the touch display device is not described in detail herein. As shown in fig. 1 and 8, the driving method includes steps S110 to S140, in which:
