Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of touch display panels, in particular to a touch display panel, a control method thereof and a display device. BACKGROUND

[0002] As a COM electrode (Common Electrode, common electrode) of an embedded self-capacitance display touch screen is divided as a TPSensor (Touch Panel Sensor, touch sensor), the COM electrode of each TPSensor needs to be driven independently by an IC (Integrated Circuit, integrated circuit) channel after being divided. Each TPSensor has an independent Tx trace (transmits a signal output by a touch IC to each touch sensor of a touch panel). The Tx trace and a data line are in the same layer or different layers. Since the TPSensor signal has coupling interference with the data signal, it causes display defects. In addition, the TPSensor needs to transmit display COM signals and touch signals (the two signals cannot be transmitted to the same TPSensor at the same time) through the Tx trace, so the panel touch signal and the display signal need to be input alternately in time. For example, for a 60Hz display panel, one frame time is 1 / 60=16.67ms, and the display time is usually about 13.67ms, and the touch time is 3ms. It is necessary to simultaneously drive the touch display, increase the actual touch and display time, and realize high-frequency display and high-frequency touch. SUMMARY

[0032] In the embodiments, the touch display panel comprises a display area, the display area is divided into a first display area and a second display area, and the two display areas do not overlap. In each of the two display areas, there are a plurality of pixel units and a plurality of touch units. The connection state of the data signal line of the pixel unit in the first display area is opposite to the connection state of the data signal line of the pixel unit in the second display area, and the connection state of the touch signal line of the touch unit in the first display area is opposite to the connection state of the touch signal line of the touch unit in the second display area. The connection state of the touch signal line of the touch unit in one display area is the same as the connection state of the data signal line of the pixel unit in the other display area.

[0033] The connection state mentioned in the above content is the connection state of the data signal line or the control signal line and the control circuit. The connection state of the data signal line or the control signal line and the control circuit can be connected or disconnected. When connected, the control signal or the data signal can be turned on, and when disconnected, the control signal or the data signal cannot be turned on.

[0034] That is, when the touch signal lines of the touch units in the first display area are connected to the control circuit, the touch signal lines of the touch units in the second display area are disconnected from the control circuit, the data signal lines of the pixel units in the second display area are connected to the control circuit, and the data signal lines of the pixel units in the first display area are disconnected from the control circuit; when the touch signal lines of the touch units in the second display area are connected to the control circuit, the touch signal lines of the touch units in the first display area are disconnected from the control circuit, the data signal lines of the pixel units in the first display area are connected to the control circuit, and the data signal lines of the pixel units in the second display area are disconnected from the control circuit.

[0035] The touch display panel provided by the embodiment of the present application comprises a plurality of pixel units in a display area and a plurality of touch units in the display area; the display area is divided into a first display area and a second display area; the connection state of the touch signal lines of the touch units in the first display area is opposite to the connection state of the touch signal lines of the touch units in the second display area; the connection state of the data signal lines of the pixel units in the first display area is opposite to the connection state of the data signal lines of the pixel units in the second display area; and the connection state of the touch signal lines of the touch units in the first display area is the same as the connection state of the data signal lines of the pixel units in the second display area, so that the connection states of the touch signal lines in the two display areas are opposite, the connection states of the data signal lines are opposite, and the display states of the touch signal lines and the data signal lines in different display areas are the same, thereby achieving the effect of simultaneous driving of touch display.

[0036] In the embodiment, the touch signal lines of the touch units and the data signal lines of the pixel units in the first display area do not overlap the second display area, and the touch signal lines of the touch units and the data signal lines of the pixel units in the second display area do not overlap the first display area.

[0037] In the embodiment, the touch signal lines of the touch units and the data signal lines of the pixel units in the first display area are routed in the first display area and do not pass through the second display area, and the touch signal lines of the touch units and the data signal lines of the pixel units in the second display area are routed in the second display area and do not pass through the first display area. In this way, the touch signal lines or the data signal lines in the first display area do not overlap the touch signal lines and the data signal lines in the second display area, and do not interfere with each other.

[0038] As an optional example, the touch signal lines of the touch units in the first display area are symmetrically arranged with the touch signal lines of the touch units in the second display area, and the data signal lines of the pixel units in the first display area are symmetrically arranged with the data signal lines of the pixel units in the second display area.

[0039] In the embodiment, the touch signal lines of the first display area and the touch signal lines of the second display area are symmetrically arranged, and the data signal lines of the first display area and the data signal lines of the second display area are symmetrically arranged. The advantage of the symmetric arrangement is that the wiring design of the signal lines of only one display area needs to be determined, and the wiring design of the entire display area can be determined.

[0040] As an optional example, the touch display panel is divided into a first display area and a second display area by a first center line, wherein the first center line is parallel to the scan lines of the touch display panel.

[0041] In the embodiment, when the first display area and the second display area of the display panel are divided, the first center line parallel to the scan lines of the touch display panel can be used as a boundary line to divide the touch display panel into the first display area and the second display area. Alternatively, a center line perpendicular to the first center line can be used to divide the display panel into the first display area and the second display area.

[0042] When the display area is divided, the touch display panel can be divided into the first display area and the second display area along the first center line by the first center line. The signal lines in the two display areas are symmetrically arranged, which is convenient for design and layout.

[0043] In the embodiment, the scan lines of the touch display panel are row-by-row scanning or column-by-column scanning, as long as all the signal lines of the touch display panel can be scanned. When the scan lines scan the pixel units in the first display area, the touch signal lines of the touch units in the second display area are connected to the control circuit. When the scan lines scan the pixel units in the second display area, the touch signal lines of the touch units in the first display area are connected to the control circuit.

[0044] In the embodiment, the connection of the signal lines of the first display area and the second display area can be that all the data signal lines of all the pixel units in the first display area are connected to the control circuit through a first data signal line switch; or each data signal line of each pixel unit in the first display area is connected to the control circuit through a first data signal line switch respectively; or all the data signal lines of all the pixel units in the second display area are connected to the control circuit through a second data signal line switch; or each data signal line of each pixel unit in the second display area is connected to the control circuit through a second data signal line switch respectively; or all the touch signal lines of all the touch units in the first display area are connected to the control circuit through a first touch signal line switch; or each touch signal line of each touch unit in the first display area is connected to the control circuit through a first touch signal line switch respectively; or all the touch signal lines of all the touch units in the second display area are connected to the control circuit through a second touch signal line switch; or each touch signal line of each touch unit in the second display area is connected to the control circuit through a second touch signal line switch respectively.

[0045] Figure 1 is a schematic diagram of an exemplary touch display panel in the embodiment, the display panel includes a touch display area 1 and a non-display area 2, wherein the non-display area 2 is further provided with a driving module 21 and a control module 22, the touch display area 1 is provided with arrayed touch units, the touch display area 1 is divided into a first display area and a second display area, the first display area and the second display area can be distributed left and right or up and down, the sizes of the two display areas can be the same or different, Figure 1 In the embodiment, the connection of the signal lines of the first display area and the second display area can be that all the data signal lines of all the pixel units in the first display area are connected to the control circuit through a first data signal line switch; or each data signal line of each pixel unit in the first display area is connected to the control circuit through a first data signal line switch respectively; or all the data signal lines of all the pixel units in the second display area are connected to the control circuit through a second data signal line switch; or each data signal line of each pixel unit in the second display area is connected to the control circuit through a second data signal line switch respectively; or all the touch signal lines of all the touch units in the first display area are connected to the control circuit through a first touch signal line switch; or each touch signal line of each touch unit in the first display area is connected to the control circuit through a first touch signal line switch respectively; or all the touch signal lines of all the touch units in the second display area are connected to the control circuit through a second touch signal line switch; or each touch signal line of each touch unit in the second display area is connected to the control circuit through a second touch signal line switch respectively.

[0046] In the embodiment, the data signal lines and the control signal lines of the first display area can be each equipped with a switch, or the data signal lines of the first display area are connected to the touch units through a switch, and the control signal lines of the first display area are connected to the touch units through a switch. The same applies to the second display area. For example,Figure 1 A first data switch 113 is provided on the data signal line 111 of the first display area, a second data switch 123 is provided on the data signal line 121, a first touch switch 114 is provided on the control signal line 112, and a second touch switch 124 is provided on the control signal line 122. The first data switch 113, the second data switch 123, the first touch switch 114, and the second touch switch 124 are connected to the control module 22. In addition, a common switch (COM switch) 115 and a common switch 125 are also included.

[0047] The control module 22 is used to control the switching states of the first data switch 113, the second data switch 123, the first touch switch 114 and the second touch switch 124, so that the driving module 21 drives the left display area 11 and the right display area 12 to start different working modes, wherein the switching states of the first data switch 113 and the second touch switch 124 are the same, and the switching states of the first data switch 113, the second data switch 123 and the first touch switch 114 are opposite.

[0048] In this embodiment, the signal lines of the touch display panel are arranged and designed so that the first center line of the touch display area divides the touch display area into a first display area and a second display area (a left display area and a right display area, or an upper display area and a lower display area). The data signal lines and control signal lines of each display area are independent and not directly connected, so that the left and right parts can control the display and touch functions respectively. Unlike the data signal lines and the control signal lines, the gate signal lines are continuous from left to right and are responsible for opening the pixels row by row for scanning. The gate signal lines are not affected by the independent design of the left and right half areas, and uniformly control the column-by-column scanning of the entire panel. The data signal lines of the left display area and the right display area are symmetrical, and the control signal lines are also symmetrical.

[0049] like Figure 2 As shown, Figure 2 for Figure 1 The switch opening and closing status in the scene. When the right display area starts the display mode, the left display area starts the touch mode. The control module controls the data switch 123 and the common switch 125 of the right display area to close, and the touch switch 124 to open, to prevent the touch signal of the right display area from interfering with the display. The touch switch 114 of the left display area is controlled to close, and the data switch 113 and the common switch 115 are opened. While not transmitting display data, the touch signal is transmitted to the touch unit of the left display area to realize touch operation. The right display area provides display data to the right display area through the closure of the data switch 123 and the common switch 125.

[0050] If the left display area starts the display mode, then Figure 3As shown, the switch 114, the switch 125 and the switch 123 are open, the switch 113, the switch 115 and the switch 124 are closed, the left display area performs data display, and the right display area performs touch operation.

[0051] In the embodiment, the data signal lines and the control signal lines are isolated in space and time by the control module controlling the control of the switches, so as to prevent them from interfering with each other. This means that when one half of the touch display panel is displaying an image, the other half can simultaneously perform touch operation without affecting the image quality. Since the display and the touch operation are time-divisional, the frequency of the display and the touch operation can be improved, so that the response speed and the display refresh rate of the touch display panel can be improved. The data signal lines are disconnected on the left and right of the display area, so that the RC load effect (which refers to the influence on signal transmission caused by the existence of resistor (R) and capacitor (C) in a circuit) of the data signal line wiring of the display area is reduced by half, the pixel charging (providing the required voltage and current for each pixel in the display to realize correct image display) is improved, and the display effect is improved. Moreover, the left and right part data signal lines are symmetrically designed, the data loading of the left and right pixels in the half display area is consistent, and the display unevenness (vertical lines or bright and dark lines) caused by the level transmission scanning of the center position gate signal line is avoided. Similarly, the touch signal lines are disconnected on the left and right of the display area, so that the signal loading of the display area is reduced by half, and the touch accuracy and sensitivity are improved.

[0052] According to a second aspect of the embodiments of the present application, the present application provides a control method of a touch display panel, which can be used in the touch display panel according to the first aspect of the embodiments of the present application. Figure 4 As shown, the method comprises the following steps.

[0054] S402, when scanning the plurality of pixel units in the second display area, connecting the control circuit with the touch signal lines of the touch units in the first display area, disconnecting the touch signal lines of the touch units in the second display area from the control circuit, connecting the control circuit with the data signal lines of the pixel units in the second display area, and disconnecting the data signal lines of the pixel units in the first display area from the control circuit.

[0055] In the embodiment, the touch display panel includes a display area, and the display area is divided into a first display area and a second display area, and the two display areas do not overlap. In each of the two display areas, there are a plurality of pixel units and a plurality of touch units. The connection states of the data signal lines of the pixel units in the first display area and the second display area are opposite, and the connection states of the touch signal lines of the touch units in the first display area and the second display area are also opposite. The connection state of the touch signal line of the touch unit in one display area is the same as the connection state of the data signal line of the pixel unit in the other display area.

[0056] The connection state mentioned in the above content is the connection state of the data signal line or the control signal line and the control circuit. The connection state of the data signal line or the control signal line and the control circuit can be connected or disconnected. When connected, the control signal or the data signal can be turned on, and when disconnected, the control signal or the data signal cannot be turned on.

[0057] That is, when the touch signal line of the touch unit in the first display area is connected to the control circuit, the touch signal line of the touch unit in the second display area is disconnected from the control circuit, the data signal line of the pixel unit in the second display area is connected to the control circuit, and the data signal line of the pixel unit in the first display area is disconnected from the control circuit; when the touch signal line of the touch unit in the second display area is connected to the control circuit, the touch signal line of the touch unit in the first display area is disconnected from the control circuit, the data signal line of the pixel unit in the first display area is connected to the control circuit, and the data signal line of the pixel unit in the second display area is disconnected from the control circuit.

[0058] Through the touch display panel of the embodiment, a plurality of pixel units in a display area and a plurality of touch units in the display area are used. The display area is divided into a first display area and a second display area. The connection state of the touch signal line of the touch unit in the first display area is opposite to the connection state of the touch signal line of the touch unit in the second display area. The connection state of the data signal line of the pixel unit in the first display area is opposite to the connection state of the data signal line of the pixel unit in the second display area. The connection state of the touch signal line of the touch unit in the first display area is the same as the connection state of the data signal line of the pixel unit in the second display area. Therefore, the connection states of the touch signal lines in the two display areas are opposite, the connection states of the data signal lines are opposite, and the display states of the touch signal lines and the data signal lines of different display areas are the same, so that the effect of simultaneous driving of touch display is achieved.
