Detailed Description
Features and exemplary embodiments of various aspects of the application are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application. In the drawings and the following description, at least some well-known structures and techniques have not been shown in detail in order not to unnecessarily obscure the present application; also, the size of the region structures may be exaggerated for clarity. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
First embodiment
As shown in fig. 1, the flexible touch panel provided in the first embodiment of the present application includes a bending area WA and non-bending areas AA located at two sides of the bending area WA, wherein the bending area WA is bendable about a bending axis S, and the flexible touch panel 1 includes a flexible substrate 10 and a plurality of touch electrodes 11 located on the flexible substrate 10.
Optionally, the flexible substrate 10 is made of polyethylene terephthalate (PET for short), and the PET has flexibility, so that the flexible touch panel is easy to bend. The touch electrode 11 located in the bending area WA includes a plurality of electrode blocks M spliced along a first direction X, and at least one edge of the electrode blocks M is parallel to a second direction Y, where the plurality of electrode blocks M are electrically connected by a stretchable connection bridge L, and the first direction X is perpendicular to an axial direction of the bending axis S, and the second direction Y is parallel to the axial direction of the bending axis S.
In this embodiment, the plurality of touch electrodes 11 include a plurality of first touch electrodes 111 continuously distributed along the first direction X and a plurality of second touch electrodes 112 continuously distributed along the second direction Y, the plurality of first touch electrodes 111 and the plurality of second touch electrodes 112 are staggered and arranged in an array, two adjacent first touch electrodes 111 are electrically connected through a metal bridging wire, two adjacent second touch electrodes 112 are electrically connected through a metal bridging wire, and the first touch electrodes 111 and the second touch electrodes 112 are insulated.
The working principle of the flexible touch panel is as follows: when a finger approaches or touches the plane where the plurality of touch electrodes 11 are located, the finger corresponds to one conductor, and the capacitance of the finger will be superimposed on the capacitance of the flexible touch panel 1, so that the capacitance of the touch panel 1 increases. During touch detection, the touch panel 1 sequentially detects a plurality of first touch electrodes 111 and a plurality of second touch electrodes 112, respectively determines coordinates along a first direction X and coordinates along a second direction Y according to changes of capacitance before and after touch, then combines the coordinates into planar touch coordinates, which is equivalent to projecting touch points on the flexible touch panel 1 to X-axis and Y-axis directions respectively, then calculates the coordinates in the X-axis and Y-axis directions respectively, and finally combines the coordinates of the touch points.
Optionally, the plurality of touch electrodes 11 are Self Capacitance (Self Capacitance), that is, each touch electrode 11 forms a Capacitance with the ground. Each touch electrode 11 is connected to the control chip through a touch lead, and the touch lead is used for sending a touch driving signal sent by the control chip to each touch electrode 11 and transmitting a touch sensing signal generated by the touch electrode 11 back to the control chip through the same touch lead. The touch electrodes 11 receive pulse information signals sent by the control chip to form a phase shift network on the whole plane.
Optionally, the plurality of touch electrodes 11 are capacitive (Mutual Capacitance), i.e. the first touch electrode 111 and the second touch electrode 112 cross each other to form a capacitor. Either one of the first touch electrode 111 and the second touch electrode 112 is a touch driving electrode, and the other is a touch sensing electrode. When an excitation signal is applied to the touch driving electrode, the mutual capacitance can be used for sensing and receiving the excitation signal on the touch sensing electrode, and the magnitude and the phase shift of the received signal are related to the frequency of the excitation signal and the magnitude of the mutual capacitance, namely the touch position is determined according to the capacitance between the touch driving electrode and the touch sensing electrode.
For convenience of description, the embodiments of the present application will be described by taking the plurality of touch electrodes 11 as the mutual capacitance type.
In this embodiment, the touch electrode located in the bending area WA includes at least one of the first touch electrode 111 and the second touch electrode 112. The touch electrode 11 of the bending area WA is configured as a plurality of electrode blocks M spliced along a direction perpendicular to the axial direction of the bending axis S, and at least one edge of the electrode blocks M is disposed parallel to the second direction Y, so that a strip-shaped gap parallel to the axial direction of the bending axis S is formed between two adjacent electrode blocks M in the bending state. Compared with the prior art that the whole touch electrode 11 is arranged in the bending area WA, the electrode blocks M formed by splicing are easier to bend, and the bending radius is smaller, so that the bending radius of the flexible touch panel can be reduced, the bending resistance of the flexible touch panel is improved, and the product competitive advantage is improved.
In addition, the plurality of electrode blocks M of the touch electrode 11 are electrically connected through a stretchable connecting bridge L, when the flexible touch panel works in a non-bending state, the stretchable connecting bridge L is in a contracted state, and the plurality of electrode blocks M of the flexible touch panel in the bending region WA are mutually spliced into a complete touch electrode 11, so that the normal touch function of the touch electrode 11 is ensured; when the flexible touch panel is in a bending state, the stretchable connecting bridge L is stretched, strip gaps among the electrode blocks M formed by splicing are enlarged, the touch performance of the touch electrode 11 can be prevented from being influenced by the fact that the connecting bridge L is broken when the touch electrode 11 is ensured to be more easily bent, and the reliability of the touch electrode 11 is improved.
According to the flexible touch panel provided by the embodiment of the application, the touch electrode 11 in the bending area WA is arranged as the plurality of electrode blocks M spliced along the direction vertical to the axial direction of the bending axis S, at least one edge of the electrode blocks M is arranged parallel to the axial direction of the bending axis, and the plurality of electrode blocks M are electrically connected through the stretchable connecting bridge. In addition, the plurality of electrode blocks M of the touch electrode 11 are electrically connected through the stretchable connection bridge L, so that the touch electrode 11 is easier to bend, and meanwhile, the connection bridge L can be prevented from being broken to affect the touch performance of the touch electrode 11, and the reliability of the touch electrode 11 is improved.
In some examples, the plurality of electrode blocks M are symmetrically disposed with respect to the central axis of the touch electrode 11 along the second direction Y, and the areas of the plurality of electrode blocks M gradually decrease in a direction away from the central axis.
Alternatively, the touch electrode 11 has a diamond shape, and the areas of the plurality of electrode blocks M gradually decrease in a direction away from the central axis. As shown in fig. 1, the electrode blocks M are symmetrically disposed along the central axis of the second direction Y relative to the touch electrode 11, so that the flexible touch panel can be bent around the bending axis S without being offset, and meanwhile, when the touch electrode is restored to the non-bending state, the touch electrode 11 spliced by the electrode blocks M can accurately position the coordinates of the touch position.
In some examples, the sum of the areas of the electrode blocks M of the touch electrode 11 in the bending area WA is smaller than the area of the touch electrode 11 in the non-bending area AA, and the touch electrode 11 and the connection bridge L are made of transparent conductive materials.
As shown in fig. 1, the sum of the areas of the electrode blocks M of the touch electrode 11 in the inflection region WA is smaller than the area of the touch electrode 11 in the non-inflection region AA. In the non-bending state, a gap is formed between two adjacent electrode blocks M of the touch electrode 11 in the bending region WA, the size of the gap is 10 μm to 20 μm, and the impedance of the touch channel increases, for example, the impedance increases by 12Ω to 15Ω.
Alternatively, the touch electrode 11 and the connection bridge L are both formed of transparent conductive materials, such as but not limited to Aluminum Zinc Oxide (AZO), gallium Zinc Oxide (GZO), indium zinc oxide (ITO), etc., so as to prevent the touch electrode 11 and the connection bridge L from being seen from the light emitting side, which affects the aesthetic appearance of the display device. In addition, the first touch electrode 111, the second touch electrode 112 and the respective connection bridge L are prepared in the same layer, so that the process steps and difficulty are not increased, and the feasibility is high.
Further, when the plurality of touch electrodes 11 of the flexible touch panel are mutual capacitance, the plurality of touch electrodes include a plurality of driving touch electrodes continuously distributed along the first direction X and a plurality of sensing touch electrodes continuously distributed along the second direction Y, and when the flexible touch panel is in a bending state, the driving voltages of the plurality of driving touch electrodes located in the bending region are greater than the driving voltages of the plurality of driving touch electrodes located in the non-bending region.
When the flexible touch panel is in a bending state, the gap between two adjacent electrode blocks M of the touch electrode 11 in the bending region WA is increased, the single-point capacitance value at the position is reduced, in order to maintain the single-point capacitance value and the detection threshold value unchanged, and ensure that the touch precision and sensitivity of the flexible touch panel are not damaged, the driving voltages of a plurality of driving touch electrodes in the bending region can be increased, for example, the driving voltages are increased by 0.5V-1V, while the driving voltages of driving touch electrodes in the non-bending region remain unchanged, and the matching is performed according to specific design.
In some examples, the connection bridge L is a diamond shape with two connection ends, formed by four lines enclosing. The material of the connecting bridge L may be a metal material, such as but not limited to molybdenum. When the electrode blocks and the connecting bridges in the bending area are in an initial shape, the diamond formed by the connecting bridges is also the initial diamond; when in a bending state, the diamond formed by the connecting bridge is stretched in the left-right direction (for example, the first direction X in fig. 3), compressed in the left-right direction (for example, the second direction Y in fig. 3), and is in a deformed diamond shape, so that the requirement of deformation of the bending region is met, the connecting bridge still can meet the requirement of conducting between the electrode blocks, but can be restored when the bending state is changed into the non-bending state.

when the flexible touch panel is in a non-bending state, controlling the voltage of the driving touch electrode positioned in the bending region to be larger than the voltage of the driving touch electrode positioned in the non-bending region;
when the flexible touch panel is in a bending state, the voltage of the driving touch electrode positioned in the bending area WA is controlled to be increased, and the voltage of the driving touch electrode positioned in the non-bending area AA is kept unchanged.
