The foregoing and other technical and scientific aspects, features and advantages of the present invention will be apparent from the following detailed description of preferred embodiments, which is to be read in connection with the accompanying drawings. While the present invention has been described in connection with the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications, equivalent arrangements, and specific embodiments thereof.
First embodiment
Referring to fig. 1, fig. 1 is a block diagram illustrating a main architecture of a touch display device according to a first embodiment of the invention. A touch display device provided in a first embodiment of the present invention includes: the display device comprises a timing controller 101, a display screen 103 electrically connected with the timing controller 101, a signal converter 105 electrically connected with the timing controller 101 and the display screen 103, and a memory 107 electrically connected with the timing controller 101. A touch sensor 111 is also disposed in the display screen 103. Preferably, the display screen 103 may be a liquid crystal display screen.
The touch sensor 111 is configured to sense a touch operation applied to the display screen 103 by a user, generate a touch sensing signal according to the touch operation, and supply the generated touch sensing signal to the timing controller 101. The touch operation may be a touch line drawing action of a finger of a user at a certain position on the display screen 103, and the content of the line drawing corresponding to the line drawing action may be a curve, a broken line, a straight line, or the like.
A timing controller 101 for temporally dividing one frame period and obtaining pixel coordinate information of the touch point and transmitting the obtained pixel coordinate information to the signal converter 105. Specifically, the timing controller 101 divides each frame period into an effective display period during which the display screen 103 outputs a display screen and a blanking period during which the display screen 103 does not output a display screen.
The timing controller 101 generates a gate control signal and a data control signal using a vertical synchronization signal Vsync, a horizontal synchronization signal Hsync, and the like, which are input from the outside. Generally, a horizontal synchronization signal is used to define the start of each gate line, and a vertical synchronization signal is used to define the start of each frame. The vertical synchronization signal Vsync and the horizontal synchronization signal Hsync are timing signals in a timing control method, please refer to fig. 2, and fig. 2 is a timing diagram of the timing control method of the touch display device. Fig. 2 shows a vertical synchronization signal Vsync, a horizontal synchronization signal Hsync, and a pixel data signal PX. In the effective display time period TD during each frame, the display data can be written into the corresponding pixels respectively at this time; during the blanking period TP of each frame period, no image data is written, and the vertical synchronization signal Vsync and the horizontal synchronization signal Hsync are used to control the synchronization between other signals. In the embodiment of the present invention, the timing controller may be an FPGA (field programmable Gate Array), or other devices.
The process of obtaining the pixel coordinate information of the touch point by the timing controller 101 and transmitting the obtained pixel coordinate information to the signal converter 105 is as follows: during the nth frame, touch parameters are obtained according to the touch sensing signals (the process is shown in part a of fig. 2), the touch parameters are analyzed during the effective display time period of the (N + 1) th frame to obtain pixel coordinate information of the touch point (the process is shown in part B of fig. 2), the obtained pixel coordinate information is stored in the memory 107 during the blanking time period of the (N + 1) th frame (the process is shown in part C of fig. 2), the pixel coordinate information stored in the memory 107 during the blanking time period of the (N + 1) th frame is read during the effective display time period of the (N + 2) th frame, and the read pixel coordinate information is transmitted to the signal converter 105, so that the signal converter 105 controls the display screen to perform image display (the process is shown in part D of fig. 2). The touch parameters generally include parameters such as coordinates of touch points, the number of touch points, and IDs of touch points. The pixel may be one of a red, green, blue pixel. Before the timing controller 101 stores the obtained pixel coordinate information in the memory 107 during the blanking period of the N +1 th frame, all the pixel coordinate information of the touch point on the display screen before the N +1 th frame is stored in the memory 107, so that the blanking period of the N +1 th frame only needs to modify part of the information in the memory 107 (i.e. the pixel coordinate information obtained during the effective display period of the N +1 th frame), and the pixel coordinate information of the part only occupies a very small part of the total amount of information (all the pixel coordinate information) currently stored in the memory 107, so that the pixel coordinate information is stored by using the blanking period of the N +1 th frame, and the time is also relatively abundant.
And the signal converter 105 is used for converting the pixel coordinate information into display information and sending the display information to the display screen 103 for displaying. The signal converter 105 may be a device that converts RGB information into an mipi (mobile Industry processor interface) signal. MIPI signals are typically signals that can be displayed on a cell phone.
The above-described screen display process is focused on the update operation part of the pixel coordinate information as a blanking period between the N +2 th frame period and the N +1 th frame period, and the total amount of information updated to the memory 107 in this period depends on the total amount of touch parameters acquired during the N-th frame period. The line drawing display can be realized by continuously repeating the process. Fig. 3 is a schematic diagram of a drawn line 301 displayed on the display screen 103, and the touch-sensitive display device is used to perform experimental verification on a touch-sensitive drawn line action acting on the display screen 103, and the verification result is shown in fig. 3, which illustrates that the touch-sensitive display device of the present invention can realize quick and accurate display of the drawn line on the touch screen by reasonably allocating and using time and fully utilizing the hiding time period to store pixel coordinate information.
In addition, as shown in fig. 4, fig. 4 is a schematic diagram illustrating that the timing controller obtains the pixel coordinate information of the touch point, and the process of obtaining the pixel coordinate information of the touch point by the timing controller 101 may be further as follows: in the blanking time period during the nth frame and the effective display time period during the (N + 1) th frame, touch parameters are obtained according to the touch sensing signals, and the touch parameters are analyzed to obtain pixel coordinate information of the touch point (the above process is shown in A, B part of fig. 4).
Preferably, the touch display device further includes a gate driver (not shown), a source driver (not shown).
Referring to fig. 2, it should be noted that the timing controller 101 generates a gate control signal for controlling the gate driver and a data control signal for controlling the source driver using a vertical synchronization signal Vsync, a horizontal synchronization signal Hsync, and the like, which are input from the outside.
The gate driver is used for transmitting a gate control signal to the gate lines on the display screen 103 to control the on/off of the plurality of switching elements connected to the gate lines. The switching element may be a thin film transistor. In one embodiment, the gate driver may receive a gate control signal from the timing controller 101 to apply a gate high voltage to the gate line, thereby turning on the switching element.
When the switching elements connected to the gate lines are turned on, the source driver transmits display data (e.g., data control signals such as red, green, and blue) to the data lines on the display screen 103 to drive the liquid crystal molecules of each pixel to display a picture. Here, the display data may include a gray level value of gray level information of the display image.
In summary, in the touch display device provided in this embodiment, the timing controller 101 obtains a touch parameter according to the generated touch sensing signal during the nth frame, analyzes the touch parameter during the effective display time period during the N +1 th frame to obtain pixel coordinate information of a touch point, stores the obtained pixel coordinate information into the memory 107 during the blanking time period during the N +1 th frame, reads the pixel coordinate information stored in the memory 107 during the blanking time period during the N +2 th frame during the effective display time period, and transmits the read pixel coordinate information to the signal converter 105; so that the signal converter 105 converts the pixel coordinate information into display information which is sent to the display screen 103 for display. The touch display device provided by the invention can realize simple, quick and accurate display of the drawn line of the touch screen.
