[0055] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0056] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0057] In many application scenarios, current folding display devices, such as outward-folding mobile phone screens or tri-fold mobile phone screens, only need half or one-third of the screen to work normally to meet functional requirements.

[0058] like Figure 1 As shown, in the related art, the touch electrode portion 1 of the display panel 100 adopts a whole electrode design that runs horizontally through the entire screen body. The display panel 100 cannot realize separate scanning of each area, resulting in increased operating power consumption of the display panel 100 and reduced touch experience. At the same time, due to the large horizontal size of the display panel 100, the electrode penetration design causes the impedance of the entire electrode to increase, thereby reducing the touch performance.

[0059] To implement partition scanning, such as Figure 2As shown, in another related art, the display panel 100 uses two touch chips 2 to respectively drive the first touch electrode portion 11 in the first display area 101 and the second touch electrode portion 12 in the second display area 102. The two touch chips 2 are used to independently drive different display areas, which increases the cost.

[0060] Based on this, the present application provides a display panel solution to solve the above problems.

[0061] Reference Figure 3 As shown, the embodiment of the present application provides a display panel 100, which has a first display area 101 and a second display area 102. The display panel 100 includes a first touch electrode portion 11, a second touch electrode portion 12 and a touch chip 2. The first touch electrode portion 11 is located in the first display area 101, the second touch electrode portion 12 is located in the second display area 102, and the first touch electrode portion 11 and the second touch electrode portion 12 are connected to the touch chip 2 in parallel. Among them, the touch chip 2 can drive the first touch electrode portion 11 and the second touch electrode portion 12 to work respectively, so as to realize the touch functions of the first display area 101 and the second display area 102 respectively.

[0062] Specifically, the touch chip 2 can simultaneously drive the first touch electrode portion 11 and the second touch electrode portion 12 to work, so that the touch function is activated simultaneously in the first display area 101 and the second display area 102. The touch chip 2 can drive one of the first touch electrode portion 11 and the second touch electrode portion 12 to work, and the other not to work, so that one of the corresponding first display area 101 and the second display area 102 activates the touch function, and the other does not activate.

[0063] The display panel 100 provided in the embodiment of the present application can realize partition scanning for different display areas by connecting the first touch electrode portion 11 and the second touch electrode portion 12 in parallel and using the same touch chip 2 for driving, without increasing the number of touch chips, and can reduce the total screen load of the display panel 100. The parallel connection can effectively reduce the channel resistance. According to the principle of resistor parallel connection, the total resistance will be smaller than a single resistor, making the transmission of electrical signals smoother and reducing the loss of signals during transmission.

[0064] At the same time, in touch operation, lower resistance helps to improve the speed and accuracy of touch response and enhance the overall touch performance, allowing users to experience a smoother and more sensitive touch experience. For example, when sliding the screen quickly or performing multi-touch operations, the position changes of the touch points can be captured more accurately.

[0065] Reference Figure 3 , Figure 4As shown, in some embodiments, the first touch electrode portion 11 is electrically connected to the touch chip 2 through the first touch signal line 31 and the second touch signal line 32, and the second touch electrode portion 12 is electrically connected to the touch chip 2 through the third touch signal line 33 and the fourth touch signal line 34. Specifically, the first touch signal line 31 and the second touch signal line 32 are connected to two opposite sides of the first touch electrode portion 11, and the third touch signal line 33 and the fourth touch signal line 34 are connected to two opposite sides of the second touch electrode portion 12.

[0066] Preferably, the second touch signal line 32 is connected to a side of the first touch electrode portion 11 close to the second touch electrode portion 12 , and the second touch signal line 32 is at least partially located in the second display area 102 .

[0067] Preferably, the first touch signal line 31 is connected to a side of the first touch electrode portion 11 away from the second touch electrode portion 12 .

[0068] Preferably, the third touch signal line 33 is connected to a side of the second touch electrode portion 12 close to the first touch electrode portion 11 , and the third touch signal line 33 is at least partially located in the first display area 101 .

[0069] Preferably, the fourth touch signal line 34 is connected to a side of the second touch electrode portion 12 away from the first touch electrode portion 11 .

[0070] Among them, the touch signal line can be connected from both sides of the touch electrode, so that the current and signal can be transmitted and distributed from two directions, which reduces the burden of the single-sided line, reduces the total screen load of the display panel 100, helps to improve the touch performance, and also provides favorable conditions for using a touch chip 2 to realize screen area scanning.

[0071] Reference Figure 3 As shown, in one embodiment, the display panel 100 includes a first selection switch 41 and a second selection switch 42, the control end of the first selection switch 41 is electrically connected to the touch chip 2, the first end of the first selection switch 41 is electrically connected to the first touch signal line 31, and the second end of the first selection switch 41 is connected to the third touch signal line 33. The control end of the second selection switch 42 is electrically connected to the touch chip 2, the first end of the second selection switch 42 is electrically connected to the second touch signal line 32, and the second end of the second selection switch 42 is electrically connected to the fourth touch signal line 34.

[0072] Preferably, the touch control chip 2 includes a first pin interface 21 , and a control end of the first selection switch 41 and a control end of the second selection switch 42 are electrically connected to the first pin interface 21 .

[0073] The touch chip 2 controls the first touch electrode portion 11 and / or the second touch electrode portion 12 to work through the first selection switch 41 and the second selection switch 42. Specifically, when the display panel 100 is in the unfolded state, the touch chip 2 controls the first selection switch 41 and the second selection switch 42 to be turned on, and the first touch electrode portion 11 and the second touch electrode portion 12 form a signal transmission path with the touch chip 2 respectively, and the first touch electrode portion 11 and the second touch electrode portion 12 work at the same time, so that the touch function of the first display area 101 and the second display area 102 is activated at the same time. When the display panel 100 is in the folded state, the touch chip 2 controls the selection function of the first selection switch 41 and the second selection switch 42, so that the first touch electrode part 11 forms a signal transmission path with the touch chip 2 through the first touch signal line 31 and the second touch signal line 32, or the second touch electrode part 12 forms a signal transmission path with the touch chip 2 through the third touch signal line 33 and the fourth touch signal line 34, so as to control the touch electrodes in different display areas respectively, for example, the first touch electrode part 11 of the first display area 101 that needs to work after folding remains working, and the second touch electrode part 12 of the second display area 102 that does not need to work stops working. The first selection switch 41 and the second selection switch 42 play a switching role. Under the control of the touch chip 2, it is possible to achieve precise control of the working state of different areas, reduce power consumption, and extend the battery life of the device. At the same time, it avoids touch operations in unnecessary areas, reduces the possibility of false touches, and improves the stability and reliability of the device when used in the folded state. For example, when only half of the screen of a foldable phone is used, the touch function of the other half of the screen can be turned off by selecting a switch to avoid accidental operation.

[0074] Reference Figure 4 As shown, in another embodiment, the touch chip 2 includes a first pin interface 21 and a second pin interface 22. The first touch signal line 31 and the second touch signal line 32 are electrically connected to the first pin interface 21. The third touch signal line 33 and the fourth touch signal line 34 are electrically connected to the second pin interface 22.

[0075] Among them, compared with the two parts of touch electrodes connected to the same pin interface (i.e., pin pin) of the touch chip 2 through the selection switch, in this embodiment, the two parts of the touch electrodes are respectively connected to the two pin pins of the touch chip 2 and are connected in parallel inside the touch chip 2 to achieve independent drive. The number of drive channels is doubled, so that the load is halved when the large screen is driven as a whole, which is beneficial to the improvement of touch performance and makes the user's touch operation on the large-screen device more sensitive and accurate; at the same time, there is no need to increase the drive channel selection circuit, which simplifies the panel circuit design and reduces the circuit complexity and failure probability.

[0076] Reference Figure 5 , Figure 6As shown, in some embodiments, when the display panel 100 is unfolded, the first touch electrode portion 11 and the second touch electrode portion 12 are arranged along a first direction (X direction in the figure).

[0077] The first touch electrode unit 11 includes a plurality of first drive electrodes 111 arranged along a first direction (X direction in the figure), and the second touch electrode unit 12 includes a plurality of second drive electrodes 121 arranged along the first direction. The first drive electrodes 111 and the second drive electrodes 121 are connected to the touch chip 2 in parallel. Specifically, the plurality of first drive electrodes 111 and the plurality of second drive electrodes 121 are arranged along the first direction. Two adjacent first drive electrodes 111 and two adjacent second drive electrodes 121 are electrically connected through a bridge structure.

[0078] In other embodiments, the first touch electrode unit 11 includes a plurality of first sensing electrodes arranged along the first direction, the second touch electrode unit 12 includes a plurality of second sensing electrodes arranged along the first direction, and the first sensing electrodes and the second sensing electrodes are connected in parallel to the touch chip 2. Specifically, the plurality of first sensing electrodes and the plurality of second sensing electrodes are arranged along the first direction. Two adjacent first sensing electrodes and two adjacent second sensing electrodes are electrically connected via a bridge structure.

[0079] In some embodiments, the display panel 100 includes a driving channel, one driving channel corresponds to a pin interface of the touch chip 2, and the driving channel extends along the first direction. The driving channel refers to a path between the touch chip 2 and the driving electrode for transmitting a driving signal. Specifically, the driving channel can be responsible for transmitting the electrical signal generated by the touch chip 2 to the first driving electrode 111 and the second driving electrode 121, respectively, so that the electrodes can generate an electric field to detect a touch operation.

[0080] Reference Figure 3 As shown, in one embodiment, the first driving electrode 111 and the second driving electrode 121 are located in the same driving channel, so as not to increase the number of driving channels and chips of the existing device. Under the premise of ensuring the realization of touch function partitioning, the simplicity and stability of the system are maintained.

[0081] Reference Figure 4 As shown, in another embodiment, the first driving electrode 111 and the second driving electrode 121 are respectively located in two driving channels spaced apart along the first direction. This doubles the number of driving channels, reduces the load of the large screen as a whole by half, and is conducive to improving the touch performance, making the touch operation of the user on the large-screen device more sensitive and accurate; at the same time, there is no need to add a driving channel selection circuit, which simplifies the panel circuit design.

[0082] Reference Figure 5 , Figure 6As shown, in some embodiments, the display panel 100 includes sensing channels, the sensing channels are cross-arranged with the driving channels, the sensing channels extend along a second direction (Y direction in the figure), and the second direction intersects with the first direction.

[0083] Preferably, the second direction is perpendicular to the first direction.

[0084] Preferably, the sensing channel includes a plurality of sensing electrodes 131 arranged along the second direction and electrically connected.

[0085] Preferably, the sensing electrodes 131 and the first driving electrodes 111 form a first touch electrode unit, and the sensing electrodes 131 and the second driving electrodes 121 form a second touch electrode unit.

[0086] The sensing channel is insulated from the driving channel. That is, the sensing electrode 131 is insulated from the first driving electrode 111 and the second driving electrode 121 . Similar to the driving channel, the sensing channel is a path for transmitting the touch sensing signal of the sensing electrode 131 .

[0087] In this embodiment, the first touch electrode portion 11 and the second touch electrode portion 12 both use mutual capacitance touch electrodes, which are usually composed of two groups of electrodes that cross each other to form a grid-like structure. Among them, the first drive electrode 111 and the second drive electrode 121 are respectively used as transmitting electrodes, and the sensing electrode 131 is used as a receiving electrode. The transmitting electrode and the receiving electrode are cross-arranged to form a plurality of mutual capacitance detection units. Under the action of the driving signal, the transmitting electrode generates an electric field. During the touch operation, when the finger approaches, the electric field distribution will change, thereby affecting the mutual capacitance between the transmitting electrode and the receiving electrode. The receiving electrode will detect the charge change caused by the change in mutual capacitance. The touch chip 2 can determine the precise position, trajectory, gesture and other information of the touch by analyzing the signal changes on the receiving electrode.

[0088] Specifically, the first driving electrodes 111, the second driving electrodes 121 and the sensing electrodes 131 may be in a rhombus or other shapes. The first driving electrodes 111, the second driving electrodes 121 and the sensing electrodes 131 may be made of transparent conductive materials (such as indium tin oxide, ITO) so as not to affect the display effect when used in a touch display device.

[0089] Reference Figure 5 As shown, in some embodiments, the display panel 100 has a wiring area 103 , and the wiring area 103 is at least partially disposed around the first display area 101 and the second display area 102 .

[0090] Preferably, the first touch signal line 31 , the second touch signal line 32 , the third touch signal line 33 and the fourth touch signal line 34 are at least partially located in the routing area 103 .

[0091] Preferably, the second touch signal line 32 includes two parallel first connection lines, and the first connection lines at least partially overlap with the orthographic projection of the second touch electrode portion 12 along the thickness direction of the display panel 100. The thickness direction of the display panel 100 is perpendicular to the first direction and the second direction respectively.

[0092] Preferably, the third touch signal line 33 includes two second connecting lines arranged side by side, and the second connecting lines at least partially overlap with the orthographic projection of the first touch electrode portion 11 along the thickness direction of the display panel 100 .

[0093] Reference Figure 7 , Figure 8 , Fig. 9 As shown, in some embodiments, the display panel 100 has a folded state and an unfolded state.

[0094] Reference Figure 8 , Fig. 9 As shown, when the display panel 100 is in the folded state, the touch chip 2 controls one of the first touch electrode portion 11 and the second touch electrode portion 12 to work, so that the corresponding first display area 101 or the second display area 102 can realize the touch function. Optionally, when the display panel 100 is in the folded state, the second display area 102 is at least partially located on the side of the first display area 101 away from the light emitting surface.

[0095] Reference Figure 7 As shown, when the display panel 100 is in the unfolded state, the touch chip 2 controls the first touch electrode portion 11 and the second touch electrode portion 12 to work simultaneously, so that the first display area 101 and the second display area 102 both realize the touch function. Specifically, when the display panel 100 is in the unfolded state, the first display area 101 and the second display area 102 are arranged along the first direction.

[0096] It has been verified that, taking the solution of the related art in which the driving electrode adopts the whole electrode design as a comparison benchmark, the total resistance is set to 100%, the preferred embodiment of the present application (such as Figure 3 The solution of the corresponding embodiment) can reduce the total resistance to 25%, reduce the loss of electrical signal transmission, improve the touch response speed and accuracy, and make the touch operation smoother and more stable. At the same time, the power consumption can be reduced from 100% to 30%. Based on the reduction of electrode resistance and partition scanning and switch control, the energy saving effect is significant, which not only prolongs the battery life of the device, but also improves the energy efficiency of the display device under different working conditions. Overall, this application is of great significance to improving the touch performance and overall performance of the device through improvements in resistance and power consumption.

[0097] Based on the same inventive concept, another embodiment of the present application further provides a display device, which includes the display panel in the above embodiment. Further, the display device can be a wearable product, a mobile phone, a computer, a television, a car display device or other display device with a display function.

[0098] A display device provided in this embodiment has a display panel 100 that connects a first touch electrode portion 11 and a second touch electrode portion 12 in parallel and uses the same touch chip 2 to drive the display panel 100, thereby realizing partition scanning for different display areas without increasing the number of touch chips and reducing the total screen load of the display panel 100.

[0099] At the same time, the parallel connection can effectively reduce the channel resistance. In touch operation, lower resistance helps to improve the speed and accuracy of touch response and improve the overall touch performance, allowing users to experience a smoother and more sensitive touch experience.
