An embodiment of the invention provides a display panel 100, a top view of the display panel 100 is shown in fig. 1, the display panel 100 may include: at least one pressure-sensitive sensor 103, the pressure-sensitive sensor 103 includes a first input terminal 1031 and a second input terminal 1032, and the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103 are respectively connected to the same fixed potential. Each pressure-sensitive sensor 103 includes a first output terminal 1033 and a second output terminal 1034, the first output terminal 1033 of each pressure-sensitive sensor 103 is connected to the first output trace c corresponding to the pressure-sensitive sensor 103, and the second output terminal 1034 of each pressure-sensitive sensor 103 is connected to the second output trace d corresponding to the pressure-sensitive sensor 103.
Before describing the display panel 100 according to the embodiment of the present invention in detail, the structure and the operation principle of the pressure-sensitive sensor 103 will be described as follows:
exemplarily, referring to fig. 2, fig. 2 is a schematic structural diagram of a pressure-sensitive sensor 103 according to an embodiment of the present invention, as shown in fig. 2, the pressure-sensitive sensor 103 includes a first resistor R1, a second resistor R2, a third resistor R3, and a fourth resistor R4, a first end of the first resistor R1 and a first end of the fourth resistor R4 are electrically connected to a first input terminal 1031, a second end of the first resistor R1 and a first end of the second resistor R2 are electrically connected to a first output terminal 1033, a second end of the fourth resistor R4 and a first end of the third resistor R3 are electrically connected to a second output terminal 1034, and a second end of the second resistor R2 and a second end of the third resistor R3 are electrically connected to a second input terminal 1032.
Specifically, referring to fig. 2, the first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 form a wheatstone bridge, when a finger presses the display panel, the first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 deform, so that the voltage output value of the wheatstone bridge changes, an operating voltage may be applied to the wheatstone bridge through the first input terminal 1031 and the second input terminal 1032, the voltage output value of the wheatstone bridge is detected through the first output terminal 1033 and the second output terminal 1034, and then the pressure value is calculated through the voltage output value of the wheatstone bridge.
Illustratively, referring to fig. 2, the first resistor R1, the second resistor R2, the third resistor R3 and the fourth resistor R4 may each be formed by a serpentine trace, specifically, taking the first resistor R1 as an example, the serpentine trace of the first resistor R1 includes a long side extending along the second extending direction and a short side extending along the third extending direction, so that the first resistor R1 may deform well in the second extending direction, and similarly, the third resistor R3 may deform well in the second extending direction, while the second resistor R2 and the fourth resistor R4 may deform well in the third extending direction, and resistance values of the first resistor R1, the second resistor R2, the third resistor R3 and the fourth resistor R4 may change according to their deformation amounts, so that a difference between the deformation amounts of the pressure sensor 103 in the second extending direction and the third extending direction may be obtained by correspondingly changing, and converted into a voltage variation to calculate the magnitude of the pressure value of the pressed point. By adopting the snake-shaped routing structure, on one hand, the first resistor R1, the second resistor R2, the third resistor R3 and the fourth resistor R4 can be ensured to have larger reference resistance values, and simultaneously, the size of the resistor is reduced, so that the resistor can be distributed in a smaller area, and the influence of temperature difference is eliminated; on the other hand, the contact area between the resistor and the substrate in contact with the resistor can be increased, so that the resistor can more accurately sense the strain of the substrate, and the pressure sensing precision is improved. The substrate in contact with the resistor can be an array substrate, a color film substrate or a cover plate.
Illustratively, referring to fig. 3, fig. 3 is a schematic structural diagram of another pressure-sensitive sensor 103 according to an embodiment of the present invention. In fig. 3, the pressure-sensitive sensor 103 is a quadrilateral, made of a semiconductor material, and includes a first side 131 and a second side 132 which are oppositely arranged, and a third side 133 and a fourth side 134 which are oppositely arranged; the pressure sensitive sensor 103 includes a first input terminal 1031 on the first side 131 and a second input terminal 1032 on the second side 132 for inputting a bias voltage signal to the pressure sensitive sensor 103; the pressure sensitive sensor 103 further comprises a first output 1033 located at the third side 133 and a second output 1034 located at the fourth side 134 for outputting a pressure sensitive detection signal from the pressure sensitive sensor 103.
Fig. 4 is an equivalent circuit diagram of the pressure-sensitive sensor 103 shown in fig. 3. Referring to fig. 3 and 4, the pressure sensing sensor 103 can be equivalent to a wheatstone bridge, which includes four equivalent resistors, respectively, an equivalent resistor Ra, an equivalent resistor Rb, an equivalent resistor Rc and an equivalent resistor Rd, wherein the region between the second input terminal 1032 and the first output terminal 1033 is the equivalent resistor Ra, the region between the second input terminal 1032 and the second output terminal 1034 is the equivalent resistor Rb, the region between the first input terminal 1031 and the first output terminal 1033 is the equivalent resistor Rd, and the region between the first input terminal 1031 and the second output terminal 1034 is the equivalent resistor Rc. When a bias voltage signal is input to the first input terminal 1031 and the second input terminal 1032, current flows through each branch in the wheatstone bridge. When the display panel is pressed, the pressure-sensitive sensor 103 receives a shearing force from a position corresponding to the display panel, and the impedance of at least one of the internal equivalent resistance Ra, the equivalent resistance Rb, the equivalent resistance Rc, and the equivalent resistance Rd of the pressure-sensitive sensor 103 changes, so that the pressure-sensitive detection signals output by the first output terminal 1033 and the second output terminal 1034 of the pressure-sensitive sensor 103 are different from the pressure-sensitive detection signals output by the first output terminal 1033 and the second output terminal 1034 of the pressure-sensitive sensor 103 when no pressure is applied, and accordingly, the magnitude of the touch pressure can be determined.
Illustratively, the pressure sensitive sensor 103 may be square in shape. The advantage of this arrangement is that it is beneficial to make the resistances of the equivalent resistor Ra, the equivalent resistor Rb, the equivalent resistor Rc and the equivalent resistor Rd the same, so that, under the condition of no pressing, the potentials between the first output terminal 1033 and the second output terminal 1034 are equal, and the pressure-sensing signals output by the first output terminal 1033 and the second output terminal 1034 are 0, which is beneficial to simplify the calculation process of the pressure value and improve the sensitivity of pressure detection.
After illustrating the structure and operation of the pressure-sensitive sensor 103, the following describes the display panel 100 shown in fig. 1 in detail:
referring to fig. 1, the display panel 100 includes a display region 101 and a non-display region 102, the display region 101 is located at a central position of the display panel 100, and the non-display region 102 is located at a periphery of the display region 101. At least one pressure-sensitive sensor 103 may be specifically provided at a right edge position of the display panel 100.
The same fixed potential may refer to two fixed potentials, and the potentials corresponding to the two fixed potentials are equal; or may be a single fixed potential, electrically connected to the first input terminal 1031 and the second input terminal 1032, respectively.
Wherein the pressure-sensitive sensor 103 can normally operate only when there is a potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103; if the two input terminals of the pressure-sensitive sensor 103 are directly and electrically connected to the same fixed potential, respectively, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, and the pressure-sensitive sensor 103 in the display panel 100 cannot work all the time. It can be understood that, in order to avoid the situation that the pressure-sensitive sensors 103 in the display panel 100 are always out of operation, the first input terminal 1031 and the second input terminal 1032 of each pressure-sensitive sensor 103 need to be ensured to be not electrically connected to the same fixed potential at the same time, respectively, i.e. the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103 can be electrically connected to the same fixed potential at the same time, respectively and indirectly; alternatively, one input terminal of the pressure-sensitive sensor 103 is directly electrically connected to a fixed potential, and the other input terminal of the pressure-sensitive sensor 103 is indirectly electrically connected to another fixed potential (the potentials corresponding to the two fixed potentials are the same), so that any one of the pressure-sensitive sensors 103 can be in an operating state at a certain stage. The direct electrical connection means that two components are not connected through a component with a switch or a switch-like function; the indirect electrical connection means that two components are connected through a component having a switch or a function similar to a switch.
In the embodiment of the present invention, the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103 are respectively connected to the same fixed potential, wherein when the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103 are respectively conducted to the same fixed potential, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, and at this time, static electricity can enter through one input terminal and be led out through the other input terminal of the pressure-sensitive sensor 103, so that the pressure-sensitive sensor 103 cannot be damaged by static electricity, and thus the antistatic capability of the pressure-sensitive sensor 103 can be improved, and further the antistatic capability of the display panel 100 is improved.
In addition, in the prior art, the pressure-sensitive sensor 103 is always in an operating state, and the pressure-sensitive sensor 103 generates power consumption and generates heat when operating, and heat generated when the pressure-sensitive sensor 103 operates may blacken the screen of the display panel 100, thereby affecting the display effect.
It should be noted that, besides the at least one pressure-sensitive sensor 103 (see fig. 1) may be disposed at a single-side edge of the display panel 100, the at least one pressure-sensitive sensor 103 may be symmetrically disposed at an opposite-side edge of the display panel 100, or the at least one pressure-sensitive sensor 103 may be disposed in the display area 101, which may be specifically disposed according to actual requirements and is not described herein again.
Optionally, an embodiment of the present invention further provides another display panel 100, a top view of the display panel 100 is shown in fig. 5, and on the basis of the structure shown in fig. 1, in fig. 5, the display panel 100 may further include:
a first switching transistor 104, a control terminal a1 of the first switching transistor 104 being electrically connected to a first control voltage signal line g, a first terminal a2 of the first switching transistor 104 being electrically connected to a first input terminal 1031 of the pressure sensitive sensor 103, a second terminal a3 of the first switching transistor 104 being electrically connected to a first voltage signal line e;
a second switching transistor 105, a control terminal b1 of the second switching transistor 105 being electrically connected to the first control voltage signal line g, a first terminal b2 of the second switching transistor 105 being electrically connected to the first input terminal 1031 of the pressure sensitive sensor 103, a second terminal b3 of the second switching transistor 105 being electrically connected to the first fixed potential;
a third switching transistor 106, wherein a control terminal c1 of the third switching transistor 106 is electrically connected to the first control voltage signal line g, a first terminal c2 of the third switching transistor 106 is electrically connected to the second input terminal 1032 of the pressure sensitive sensor 103, and a second terminal c3 of the third switching transistor 106 is electrically connected to the second voltage signal line f;
a fourth switching transistor 107, a control terminal d1 of the fourth switching transistor 107 is electrically connected with the first control voltage signal line g, a first terminal d2 of the fourth switching transistor 107 is electrically connected with the second input terminal 1032 of the pressure sensitive sensor 103, a second terminal d3 of the fourth switching transistor 107 is electrically connected with a second fixed potential, and the second fixed potential is the same as the first fixed potential;
wherein the first switching transistor 104 and the third switching transistor 106 are switching transistors of a first type, and the second switching transistor 105 and the fourth switching transistor 107 are switching transistors of a second type.
In order to make the reader clearly understand the specific structures of the first to fourth switching transistors 104 to 107, an enlarged schematic diagram of a rectangular frame a in fig. 5 is shown, which is shown in fig. 6.
The first control voltage signal line g is used to control the on/off of each switching transistor. The first voltage signal line e and the second voltage signal line f are electrically connected to provide a voltage signal to the pressure sensor 103.
The first control voltage signal line g, the first voltage signal line e, and the second voltage signal line f may be connected to a driving chip (not shown in fig. 5) for providing voltage signals to the three signal lines, so that the three signal lines can function independently.
In general, the on conditions of the different types of switching transistors are different, and the operating states of the first to fourth switching transistors 104 to 107 can be controlled by adjusting the level of the potential corresponding to the voltage signal in the first control voltage signal line g, so that the operating states of the same type of switching transistor are the same and the operating states of the different types of switching transistors are opposite, for example, so that the first type of switching transistor is turned on and the second type of switching transistor is turned off, or so that the first type of switching transistor is turned off and the second type of switching transistor is turned on.
If the first type of switching transistor is turned on, the second type of switching transistor is turned off, that is, the first switching transistor 104 and the third switching transistor 106 are turned on, and the second switching transistor 105 and the fourth switching transistor 107 are turned off, then the first input terminal 1031 of the pressure-sensitive sensor 103 is turned on with the voltage signal in the first voltage signal line e, and the second input terminal 1032 of the pressure-sensitive sensor 103 is turned on with the voltage signal in the second voltage signal line f, wherein when the potential corresponding to the voltage signal in the first voltage signal line e is different from the potential corresponding to the voltage signal in the second voltage signal line f, the pressure-sensitive sensor 103 can be in an operating state, that is, a pressure-sensitive detecting and sensing state.
If the first type of switching transistor is turned off, the second type of switching transistor is turned on, that is, the first switching transistor 104 and the third switching transistor 106 are turned off, and the second switching transistor 105 and the fourth switching transistor 107 are turned on, then the first input terminal 1031 of the pressure-sensitive sensor 103 is turned on at a first fixed potential, and the second input terminal 1032 of the pressure-sensitive sensor 103 is turned on at a second fixed potential, wherein, since the second fixed potential is the same as the first fixed potential, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, the pressure-sensitive sensor 103 is in a non-operating state, meanwhile, static electricity can enter from one input terminal and exit from the other input terminal of the pressure-sensitive sensor 103, and the pressure-sensitive sensor 103 is not damaged by static electricity, so that the antistatic ability of the pressure-sensitive sensor 103 can be improved, thereby improving the antistatic capability of the display panel 100. In addition, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, and the pressure-sensitive sensor 103 does not work, so that power consumption is not generated, and heat is not generated, thereby reducing the possibility that the screen of the display panel 100 is burned black, and further improving the display effect.
Alternatively, referring to fig. 5, the first fixed potential and the second fixed potential may be ground potentials, respectively.
If the first type of switching transistor is turned off, the second type of switching transistor is turned on, that is, the first switching transistor 104 and the third switching transistor 106 are turned off, and the second switching transistor 105 and the fourth switching transistor 107 are turned on, then both the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103 are turned on to the ground potential, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, the pressure-sensitive sensor 103 is in a non-operating state, meanwhile, static electricity enters from one input terminal and is led out from the other input terminal of the pressure-sensitive sensor 103, and the pressure-sensitive sensor 103 is not damaged by static electricity, so that the antistatic capability of the pressure-sensitive sensor 103 can be improved, and the antistatic capability of the display panel 100 is further improved. In addition, there is no potential difference between the first input terminal 1031 and the second input terminal 1032 of the pressure-sensitive sensor 103, and the pressure-sensitive sensor 103 does not work, so that power consumption is not generated, and heat is not generated, thereby reducing the possibility that the screen of the display panel 100 is burned black, and further improving the display effect.
Optionally, the first type of switching transistor is an N-type switching transistor, and the second type of switching transistor is a P-type switching transistor (not shown); alternatively, the first and second electrodes may be,
referring to fig. 5, the first type switching transistor is a P-type switching transistor, and the second type switching transistor is an N-type switching transistor.
When the electric potential in the first control voltage signal wire g is higher, the P-type switch transistor is cut off, and the N-type switch transistor is turned on; when the potential in the first control voltage signal line g is low, the N-type switching transistor is turned off, and the P-type switching transistor is turned on. The first to fourth switching transistors 104 to 107 can be controlled to be turned on or off by controlling the high or low of the potential in the first control voltage signal line g.
Optionally, referring to fig. 5, the first voltage signal line e is an on-state voltage signal line or an off-state voltage signal line.
The on-state voltage signal line may be used to provide an on-state voltage signal VGH, and the off-state voltage signal line may be used to provide an off-state voltage signal VG L.
The display panel 100 has a plurality of circuits, different circuits have a plurality of switching transistors respectively (all the circuits and all the switching transistors in the display panel 100 are not shown in fig. 5), the plurality of switching transistors provided in different circuits are electrically connected to at least one on-state voltage signal line and/or at least one off-state voltage signal line, and the at least one on-state voltage signal line and/or the at least one off-state voltage signal line can be used to control the on/off of the switching transistors in different circuits, so that different circuits can implement different functions.
