Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
It will be appreciated that the tactile feedback in the embodiments of the present application is based on an electrostatic force feedback technique, which uses a varying electric field to generate an intermittent coulomb attraction between the finger skin and the conductive body, as shown in fig. 1. When the capacitor is charged with electric charges, a positive electric field appears above the display screen, and negative charge accumulation is generated by the skin induction of fingers when the fingers of a person contact the upper surface of the insulating film due to the attraction effect of the electric field. When a finger passes through the electric field, because the finger is a poor conductor, charges gathered at the finger end cannot flow away, and the charges and different electric fields generate interaction of coulomb force, so that downward stress is increased. When the electric field changes, the finger is stressed and changes, and the human perception cell can perceive the finger. However, because the sensing frequency of the human finger is about 50Hz, when the refreshing rate of the tactile feedback force is higher than 50Hz, the force applied to the finger cannot be distinguished, so that the electrostatic force can be used for expressing dynamic force touch. The refresh rate of current display screens is generally higher than this refresh rate, which can provide a user with advantageous tactile feedback.
Based on the principle, in order to achieve fusion of the touch feedback device and the screen in virtual reality based on electrostatic force touch feedback, namely to reduce the volume of equipment and reduce the complexity and cost of calculation, the embodiment of the application utilizes the electrostatic force touch feedback principle to achieve fusion of the touch device and the screen, and the capacitance is arranged on the surface close to the display panel, so that when a touch sensing tissue (such as a finger and the like) slides across the surface of the screen, the finger is subjected to coulomb force, and sensing cells of the finger of a user sense the touch corresponding to the current scene of the real panel.
It is further understood that the Display panel in the embodiment of the present application may be a Liquid Crystal Display (LCD) or an Organic Light Emitting Display (OLED), that is, the tactile feedback point excited by the LC oscillator in the embodiment of the present application may be used in the LCD or the OLED.
For convenience of understanding and explanation, the display panel, the driving method, and the display device provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 10.
Fig. 4 is a schematic structural diagram of a display panel provided in an embodiment of the present application, and as shown in fig. 3, the display panel includes:
the display panel comprises a first substrate, a second substrate and a common electrode layer between the first substrate and the second substrate, wherein the second substrate is close to the surface of the display panel, a plurality of capacitor plates are arranged on the second substrate, and each capacitor plate and the common electrode layer are combined to form a capacitor, so that after the capacitor is charged, an electrostatic field is formed above the display panel.
Specifically, in order to realize the integration of the haptic device and the display screen, the embodiment of the present application is lifted to the surface of the display panel. Specifically, a plurality of capacitor plates may be disposed in a substrate layer on the top of the display panel, so that the capacitor plates in the pixel layer and a common electrode layer on the surface of a substrate (second substrate) at the bottom of the display panel together form a capacitor structure, and thus a tactile feedback point may be formed at the capacitor, so that a positive electric field is formed on the surface of the display panel after the capacitor is charged. When the limbs of a user, such as fingers, touch the positions corresponding to the tactile feedback points on the display panel, the fingers gather corresponding charges under the action of the charges on the capacitors, and the fingers sense the tactile feedback under the action of coulomb force based on the action of an electrostatic field.
Further, as shown in fig. 5, in order to form a better capacitor structure and enable a user's finger to generate a more sensitive touch feeling, the second substrate may include a pixel layer and an insulating layer, the insulating layer is disposed near the common electrode layer of the first substrate, and the capacitor plate is disposed in the pixel layer, so that the capacitor plate, the insulating layer, and the common electrode layer form a capacitor together.
Alternatively, as shown in fig. 6, in another embodiment, the insulating layer is close to the surface of the display panel, and the capacitor plate is disposed in the insulating layer, for example, the capacitor plate may be disposed in an insulating glass layer, so that the capacitor plate, the pixel layer and the common electrode layer in the insulating glass together form a capacitor.
It can be understood that, in the above embodiment, in order to better implement the generation of coulomb force on the user's finger touching the display screen, the position of the ITO layer in the conventional LCD or OLED layout is lowered below the RBG layer, and a capacitor is formed through the insulating layer and the common electrode, and meanwhile, the influence of the electric field from the TFT on the charging capacitor is isolated, so as to ensure that one charging capacitor forms an electric field which can be changed in real time, i.e., one touch pixel point. Therefore, continuous attraction can be generated to the fingers through repeated charging and discharging processes, and the continuous mapping relation between the touch feedback and the screen display object is completed.
Optionally, as shown in fig. 3, the setting of the tactile feedback points may be set corresponding to pixel points of the display panel, that is, one tactile feedback point is set corresponding to each pixel point. For example, each pixel in the pixel layer is provided with a capacitor, forming a tactile feedback point for each pixel. Immediately, through the distribution mode, multi-point tactile feedback can be realized on the screen, namely, a plurality of fingers can simultaneously sense a plurality of tactile feedback forces, and different areas of a single finger can realize a plurality of tactile senses.
Fig. 7 is a schematic structural diagram of a display panel according to another embodiment of the present application. As shown in fig. 7, the LCD display screen is fused with tactile feedback points:
the liquid crystal display panel specifically comprises a backlight plate, a Polaroid (POL), an array substrate, a liquid crystal layer, a common electrode layer (ITO), a pixel layer and an insulating layer. A capacitor is arranged at the position corresponding to each pixel point in the pixel layer, namely a touch feedback point is formed on the surface close to the display panel. When the capacitor stores electric charge, an electrostatic field is formed above the display screen, and negative charge accumulation is generated by the skin induction of fingers when the fingers of a person contact the upper surface of the insulating film due to the attraction effect of the electric field. When a finger slides through an electric field on the display panel, because the finger is a poor conductor, charges gathered at the end of the finger cannot flow away, and can generate coulomb force interaction with different electric fields, and downward stress increases the finger of a user to pass through a touch feedback point (a position corresponding to a capacitor).
Fig. 8 is a schematic structural diagram of a display panel according to yet another embodiment of the present application. As shown in fig. 8, the OLED display screen is fused with tactile feedback points.
The display device specifically comprises a polarizer (such as PL), an array substrate, a common electrode layer (ITO), a pixel layer and an insulating layer, wherein the pixel layer can be an electroluminescent layer. A capacitor is arranged at the position corresponding to each pixel point in the pixel layer, so that a touch feedback point is formed on the surface close to the display panel. When the capacitor stores charges, the user finger passes through the tactile feedback point (the position corresponding to the capacitor), the charges accumulated at the finger end cannot flow away, the charges and different electric fields generate coulomb force interaction, and the downward force is applied to increase the passing of the user finger through the tactile feedback point (the position corresponding to the capacitor).
Preferably, the capacitor in the present application may be driven by using a pixel voltage, or a driving circuit may be additionally provided.
For example, fig. 9 shows a schematic circuit diagram of driving by pixel voltage, and as shown in the figure, each pixel driving point may be led out, a gate of the tactile feedback is connected to a gate of the pixel circuit through a diode, and the diode is turned on from the pixel transistor to the tactile transistor, and charge storage is performed by a capacitor in a tactile feedback portion.
In this driving mode, when the gate voltage in the pixel circuit turns on the transistors (T1, T2, and T3) and turns on the transistor T4 at the same time, the transistor is in a saturated state, and then the pixel voltage of each pixel sub-unit is gradually applied to the pixel transistor according to the data signal of the frame to be displayed, so that the pixel transistor is discharged. At this time, the pixel voltage of each pixel sub-unit charges the capacitance in the haptic circuit through the diode.
It can be understood that, since the pixel voltage of each pixel unit represents the object property of the image frame displayed on the display screen, the time length for charging the capacitor is also determined accordingly, i.e. the self-adaptive adjustment according to the tactile feedback force is realized.
After charging is finished, the capacitor stores charges to become a touch feedback point, when a finger passes through a screen, the charges are released to perform touch feedback, before the next frame starts, the charges are cleared by utilizing Reset, the charge amount of the next corresponding pixel point is put in, and refreshing of the touch pixel point is finished in a circulating mode.
Fig. 10 is a schematic diagram of a driving circuit for driving a capacitor by a separate driving circuit, wherein the driving circuit of the display panel includes a pixel circuit and a tactile feedback circuit, and a tactile voltage in the tactile feedback circuit drives the capacitor, so that the charged capacitor generates an electrostatic force to a user's tactile tissue contacting the display panel. The haptic feedback circuit may include an array of capacitors in a plurality of rows and columns.
It can be understood that, in the driving mode, the relationship between the charging time and the charging size of each display object and the capacitor can be calculated through the relationship between the tactile feedback force and the electrostatic force, and the control of each tactile pixel point is accurately realized.
On the other hand, the embodiment of the present application further provides a display device, which includes the display panel in the above embodiment.
To sum up, according to the display panel, the driving circuit, and the display device provided in the embodiments of the present application, the capacitor structure is disposed in the first substrate close to the display panel, so that each capacitor plate and the common electrode on the surface of the second substrate form a capacitor, and thus when an object is displayed on the display panel, the capacitor is continuously charged, and when a user tactile sensing tissue is in contact with a pixel feedback point corresponding to the capacitor on the display panel, an electrostatic field generated by the capacitor exerts coulomb force on the user tactile sensing tissue, so that the user generates tactile feedback, fusion of the tactile feedback device and the display screen is achieved, a relation between the tactile feedback and a continuous mapping of a screen display object is completed, and a device volume is reduced.
