Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In the related technology, the Braille display panel which transmits information in a vibration mode has large stimulation to the fingertips of the blind person and is not beneficial to long-term use.
Exemplarily, fig. 1 is a schematic structural diagram of a braille display panel according to an embodiment of the present invention, and as shown in fig. 1, the braille display panel 0 includes: a substrate 01, a flexible substrate 02, a plurality of conductor blocks 03, and a magnetic film layer 04.
The substrate base plate 01 is opposite to the flexible base plate 02, the conductor blocks 03 and the magnetic film layer 04 are located between the substrate base plate 01 and the flexible base plate 02, the conductor blocks 03 are located on one side, close to the flexible base plate 02, of the substrate base plate 01, and the magnetic film layer 04 is located on one side, close to the substrate base plate 01, of the flexible base plate 02.
The orthographic projection of the conductor block 03 on the substrate 01 is overlapped with the orthographic projection of the magnetic film layer 04 on the substrate 01, and the conductor block 03 and the magnetic film layer 04 are spaced in the direction from the substrate 01 to the flexible substrate 02.
The conductor block 03 is electrically connected to a controller (not shown in fig. 1) for receiving a display electric signal provided from the controller in the display mode.
In summary, the braille display panel provided by the embodiment of the invention includes the conductor block and the magnetic film layer, so that the controller can apply an electrical signal to the conductor block, so that the magnetic field generated by the conductor block generates an acting force on the magnetic film layer, and the magnetic film layer is controlled to drive the flexible substrate to deform, such as to be concave or convex, thereby achieving the purpose of displaying braille. The Braille display panel is simple in structure, and the flexible substrate in contact with the fingers of the blind is soft in material, so that the fingers cannot be stimulated. Therefore, the requirement of the blind for using the Braille display panel for a long time can be met.
The braille display panel 0 according to the embodiment of the invention can apply different electric signals to the conductor block 03 through the controller, so that the conductor block 03 generates a magnetic field. At this time, the portion of the magnetic film layer 04 facing the conductor block 03 can move the flexible substrate 02 under the action force (attractive force or repulsive force) of the magnetic field. When the acting force is an attractive force, the portion of the magnetic film 04 can drive the flexible substrate 02 to move toward the conductor block 03, so as to form a recess as shown in fig. 2. When the force is repulsive force, the magnetic film 04 can drive the flexible substrate 02 to move away from the conductor block 03 to form a protrusion as shown in fig. 3. When the braille display panel 0 displays braille, part of the region in the flexible substrate 02 is raised and part of the region is depressed, thereby realizing braille display.
Alternatively, the braille display panel 0 may have only the depressions shown in fig. 2 in the flexible substrate 02 without the projections shown in fig. 3 when displaying braille, which is not limited by the embodiment of the present invention.
Among them, the recess or the projection in the flexible substrate 02 can be controlled by the magnitude of the current inputted into the conductor block 03. When the current in the conductor block 03 is large, the acting force of the magnetic field generated by the conductor block 03 on the magnetic film layer 04 is strong, and at this time, the degree of deformation of the flexible substrate 02 is large, and the recess or the protrusion in the flexible substrate 02 is obvious. When the current in the conductor block 03 is small, the acting force of the magnetic field generated by the conductor block 03 on the magnetic film layer 04 is weak, and at this time, the deformation degree of the flexible substrate 02 is small, and the recess or the protrusion in the flexible substrate 02 is less obvious.
Alternatively, the material of the base substrate 01 may be a rigid material, such as glass or transparent resin. The substrate 01 may also be made of a flexible material, such as Polyimide (PI). When the material of the base substrate is a flexible material, the base substrate 01 and the flexible substrate 02 may be the same, and in the embodiment of the present invention, the base substrate and the flexible substrate are made of polyimide.
Optionally, the material of the magnetic film layer 04 includes: magnets or metals. For example, when the material of the magnetic film 04 includes a metal, the metal may be iron, cobalt, nickel, or the like. The magnetic film layer 04 may cover all or part of the flexible substrate 02.
Alternatively, the orthographic projection of the conductor block 03 on the substrate base plate 01 may be circular, rectangular, triangular, or the like, which is not limited in the embodiment of the present invention. In the embodiment of the present invention, the orthogonal projection of the conductor block 03 on the substrate base plate 01 is rectangular. Alternatively, the size of the conductor blocks may be on the order of millimeters (i.e., the conductor blocks may have a length and width on the order of millimeters). When the size of the conductor block reaches the millimeter level, the number of conductor blocks per unit area increases, and the resolution of the braille display can be improved. A plurality of conductor blocks 03 may be arranged in an array.
Optionally, the braille display panel in fig. 1 further includes: and a seal structure 08. The sealing structure 08 is located between the base substrate 01 and the flexible substrate 02, and seals a space between the base substrate 01 and the flexible substrate 02. At this time, the structures other than the sealing structure 08, the base substrate 01, and the flexible substrate 02 in the braille display panel are sealed between the sealing structure 08, the base substrate 01, and the flexible substrate 02. The sealing structure 08, the flexible board 02, and the base board 01 may be made of the same material. For example, when the sealing structure 08, the flexible substrate 02, and the substrate 01 are made of flexible materials such as polyimide, the braille display panel can be bent and is convenient to carry.
Optionally, the braille display panel provided by the embodiment of the invention may have a touch function, and at this time, the braille display panel may further include a touch electrode layer.
Exemplarily, fig. 4 is a schematic structural diagram of another braille display panel according to an embodiment of the present invention, and fig. 4 does not show the substrate 01, the flexible substrate 02, and the sealing structure 08. As shown in fig. 4, the braille display panel 0 may include: and the touch electrode layer (including the first touch electrode stripes 051 and the second touch electrode stripes 052) is positioned between the substrate base plate 01 and the flexible base plate 02. The touch electrode layer is insulated from both the conductor block 03 and the magnetic film layer 04, and is electrically connected to a controller (not shown in fig. 4) for receiving a touch electrical signal provided by the controller in a touch mode.
Note that the braille display panel has a touch mode and a display mode. When the Braille display panel is in the touch mode, the display mode is closed. When the Braille display panel is in the display mode, the touch mode is closed. The touch mode and the display mode of the braille display panel can be set by the user, for example, a selection button (which may be a physical button or a displayed braille button) is arranged on the braille display panel, and the user can click the selection button to select to enter the touch mode or the display mode currently.
Further, fig. 5 is a schematic diagram of the VV shown in fig. 4 according to an embodiment of the present invention. Also, fig. 5 shows a substrate base plate 01, a flexible base plate 02, and a sealing structure 08; FIG. 5 is a schematic structural diagram of the first electrode stripe 051, the second electrode stripe 052 and the magnetic stripe 041 in FIG. 4 according to an embodiment of the present invention. Referring to fig. 4, 5 and 6, the touch electrode layer includes: the braille display panel further comprises a plurality of first electrode bars 051 and a plurality of second electrode bars 052 which are positioned at the same layer with the magnetic film layer, and the braille display panel further comprises an insulating layer 06.
The insulating layer 06 is located between the substrate base plate 01 and the conductor block 03, the plurality of first electrode bars 051 are located between the substrate base plate 01 and the insulating layer 06, the plurality of conductor blocks 03 are arranged in an array, and the plurality of first electrode bars 051 are sequentially arranged along one direction (taking the direction as the row direction x in the embodiment of the invention as an example) of the row direction x and the column direction y of the conductor block 03.
The magnetic film 03 includes a plurality of magnetic strips 041 disposed on the same layer as the second electrode strips 052, and the magnetic strips 041 and the second electrode strips 052 are alternately arranged in the other one of the row direction x and the column direction y (the lower is taken as an example of the column direction y in the embodiment of the invention). The orthographic projection of each first electrode bar 051 on the substrate base 01 is overlapped with the orthographic projection of the plurality of second electrode bars 052 on the substrate base 01.
The plurality of magnetic strips 041 are in one-to-one correspondence with the plurality of conductor blocks 03 including the plurality of conductor blocks 03, and an orthographic projection of each magnetic strip 041 on the substrate base 01 overlaps with an orthographic projection of the corresponding conductor block set 03 on the substrate base 01. Wherein, when the other direction is the row direction x, each group of conductor blocks 03 comprises a column of conductor blocks 03; when the other direction is the column direction y, each group of conductor blocks 03 includes one row of conductor blocks 03. In the embodiment of the present invention, each group of conductor blocks 03 includes one row of conductor blocks 03.
Optionally, the orthographic projection of the touch electrode layer on the substrate base plate 01 is positioned outside the orthographic projection of the electrode block 03 on the substrate base plate 01. Therefore, the influence between the touch electrode layer and the electrode block 03 can be reduced as much as possible, and effective touch and braille display can be realized.
Alternatively, the Braille display panel may include m rows and n columns of conductor blocks 03, with m ≧ 1 and n ≧ 1.
As shown in fig. 7, the braille display panel further includes: m x n connection traces 11 corresponding to the m rows and n columns of conductor blocks 03 one by one, and each conductor block 03 is electrically connected to the controller 09 through the corresponding connection trace 11.
Alternatively, as shown in fig. 8, the braille display panel may further include: and m rows and lines of gate lines C, n and data lines D and m rows and n columns of transistors 07 on the substrate. The m rows and n columns of transistors 07 are electrically connected with the m rows and n columns of conductor blocks 03 one by one, the ith row of transistors is electrically connected with the ith grid line, the jth column of transistors is electrically connected with the jth data line, i is more than or equal to 1 and less than or equal to m, and j is more than or equal to 1 and less than or equal to n. Each conductor block is connected to a thin film transistor so that the transistor can be turned on or off by the gate line, and then the conductor block can be turned on or off by the data line when the transistor is turned on.
The operation principle of the touch electrode layer will be explained below.
For example, the first electrode stripes 051 may be driving electrode stripes, and the second electrode stripes 052 may be sensing electrode stripes; or the second electrode stripes 052 are driving electrode stripes, and the first electrode stripes 051 are sensing electrode stripes. The controller may sequentially input a touch driving signal (high level signal) to a plurality of driving electrode bars (e.g., 11-1 to 11-5 in fig. 9), and sequentially output a touch sensing signal (high level signal) for each driving electrode bar to which the touch driving signal is input (e.g., 12-1 to 12-2 in fig. 10). At this time, each driving electrode strip and the plurality of sensing electrode strips can be coupled to form a capacitor with a certain capacitance. The controller may determine whether the intersection position of each driving electrode strip and each sensing electrode strip is touched based on the capacitance formed by the driving electrode strip and the sensing electrode strip.
For example, when the crossing position of the driving electrode bar and the sensing electrode bar is not touched, the circuit formed by the driving electrode bar and the sensing electrode bar may be as shown in fig. 11. One end of the driving electrode bar 11 and one end of the sensing electrode bar 12 are electrically connected to the ground GND. At this time, a capacitance is formed between the other end of the driving electrode bar 11 and the other end of the induction motor bar 12, and an electric field as shown in fig. 11 exists between the other end of the driving electrode bar 11 and the other end of the induction motor bar 12.
As shown in fig. 12, when the crossing position of the driving electrode bar 11 and the sensing electrode bar 12 is touched (e.g., touched by the finger Z in fig. 12), the circuit formed by the driving electrode bar and the sensing electrode bar may be as shown in fig. 13. At this time, the finger Z forms a path with the ground GND, and the current on the path is i2, and if the other end of the driving electrode bar 11 and the other end of the sensing electrode bar 12 are connected to form a path with the driving electrode bar 11, the sensing electrode bar 12 and the ground GND, the current on the path is i 1. It can be seen that when the external conductor (finger Z) touches on the braille display panel, the external conductor will shunt a portion of the current in the braille display panel, so that the capacitance between the driving electrode bars 11 and the sensing electrode bars 12 changes (decreases). Therefore, the controller can determine the touch position of the external conductor according to the crossing positions of the driving conductive strips 11 and the sensing conductive strips 12 with the changed capacitance.
In addition, the capacitance between the driving electrode strips 11 and the sensing electrode strips 12 is related to the distance between the two electrode strips as follows: c ═ epsilon S/4 pi kd; wherein epsilon is a dielectric constant, S is an overlapping area of an orthographic projection of the driving electrode strips 11 on the substrate base plate and an orthographic projection of the sensing electrode strips 12 on the substrate base plate, k is an electrostatic force constant, and takes the value of 8.9880 multiplied by 10 (unit: Newton-meter/coulomb), and d is a distance between the driving electrode strips 11 and the sensing electrode strips 12 in a direction perpendicular to the substrate base plate 01. After the controller detects the capacitance between the driving electrode strip and the induction electrode strip, the distance s can be calculated according to the capacitance and the formula, and then the touch force of the external conductor pair is obtained according to the distance s.
In addition, the controller can record the current touch time when detecting that the Braille display panel is touched. The controller can also calculate the time interval between every two touches when detecting that the Braille display panel is continuously touched. The controller can also determine the touch area of each touch according to the detected touch position when the Braille display panel is touched each time.
The controller can also control the Braille display panel to display the Braille based on the touch position, the touch area, the touch strength, the time interval and the like. For example, when a time interval between two consecutive touches of the braille display panel is less than a time interval threshold, the controller may control the braille display panel to implement a page-turning function, a font enlarging function, or a font reducing function. The controller can also control the Braille display panel to adjust the concave degree of the displayed Braille characters according to the touch force and the touch area. In the touch mode, the controller may determine strokes (e.g., all or part of strokes of a character) written by the user according to the touch position and the variation degree of the distance between the electrodes during the touch. And then, the controller can calibrate the strokes and control the Braille display panel to display the calibrated strokes so that the user can judge whether the input strokes are correct or not. The controller may also control the braille display panel to implement other functions according to the detected touch position, touch area, touch strength, time interval, and the like, which is not limited in the embodiment of the present invention.
The above embodiments take the touch electrode layer as a mutual capacitance type touch electrode layer as an example. When the touch electrode layer is a self-capacitance touch electrode layer, the touch electrode layer may include an electrode block layer (including a plurality of touch electrode blocks) and a ground electrode layer, a capacitor may also be formed between each electrode block and the ground electrode layer, and the controller may perform touch detection based on the capacitor. Optionally, the electrode block layer may be located on the layer where the first electrode bar is located, the ground electrode layer may be located on the layer where the second electrode bar is located, and the braille display panel also includes the insulating layer. Optionally, the electrode block layer may be located on the layer where the second electrode bar is located, the ground electrode layer may be located on the layer where the first electrode bar is located, and the braille display panel also includes the insulating layer. Optionally, the plurality of conductor blocks are multiplexed to serve as a ground electrode layer, the electrode layer is located on the layer where the first electrode bar is located, and the braille display panel also comprises the insulating layer. Optionally, the plurality of conductor blocks are multiplexed to serve as a ground electrode layer, the electrode layer is located on the layer where the second electrode bars are located, and the braille display panel does not include the insulating layer.
In summary, the braille display panel provided by the embodiment of the invention includes the conductor block and the magnetic film layer, so that the controller can apply an electrical signal to the conductor block, so that the magnetic field generated by the conductor block generates an acting force on the magnetic film layer, and the magnetic film layer is controlled to drive the flexible substrate to deform, such as to be concave or convex, thereby achieving the purpose of displaying braille. The Braille display panel is simple in structure, and the flexible substrate in contact with the fingers of the blind is soft in material, so that the fingers cannot be stimulated. Therefore, the requirement of the blind for using the Braille display panel for a long time can be met.
It should be noted that the braille display panel provided by the embodiment of the invention displays braille through the principle of electromagnetic induction, and the power on and off of the electromagnetic block is instantaneous, so that the braille display can be realized in real time. In addition, the Braille display panel provided by the embodiment of the invention has the advantages of simple structure, small volume and weight (similar to a mobile phone screen, and even lighter), and is relatively convenient to carry.

And 1403, oppositely arranging the substrate and the flexible substrate so that the conductor block and the magnetic film layer are positioned between the substrate and the flexible substrate, wherein the orthographic projection of the conductor block on the substrate is overlapped with the orthographic projection of the magnetic film layer on the substrate, and the conductor block and the magnetic film layer are spaced in the direction from the substrate to the flexible substrate. The conductor block is electrically connected to the controller for receiving display electrical signals provided by the controller in the display mode.
In summary, the braille display panel manufactured by the method according to the embodiment of the invention includes the conductor block and the magnetic film layer, so that the controller can apply an electrical signal to the conductor block to enable the magnetic field generated by the conductor block to generate an acting force on the magnetic film layer, thereby controlling the magnetic film layer to drive the flexible substrate to generate deformation such as a recess or a protrusion, thereby achieving the purpose of displaying braille. The Braille display panel is simple in structure, and the flexible substrate in contact with the fingers of the blind is soft in material, so that the fingers cannot be stimulated. Therefore, the requirement of the blind for using the Braille display panel for a long time can be met.
Fig. 15 is a flowchart of another method for manufacturing a braille display panel according to an embodiment of the present invention, and the manufacturing method is exemplified by manufacturing the braille display panel shown in fig. 4, and as shown in fig. 15, the manufacturing method includes:
The plurality of first electrode stripes may be sequentially arranged in a direction, which may be one of a row direction and a column direction of the plurality of conductor blocks to be formed on the substrate base.
Before manufacturing the braille display panel, a substrate base (in the embodiment of the present invention, the material of the substrate base is polyimide, for example) should be provided first, and a plurality of first conductive strips 051 as shown in fig. 16 are formed on the substrate base. It should be noted that the material of the plurality of first conductive strips 051 may be a transparent conductive material or an opaque conductive material. When the plurality of first conductive bars 051 are made of transparent conductive materials, the transparent conductive materials can be Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO) and the like; when the plurality of first conductive strips 051 are made of opaque conductive materials, the opaque conductive materials can be graphene and the like. In the embodiment of the invention, the first conductive strip 051 is made of indium tin oxide.
When a plurality of first electrode stripes are formed, a conductive material layer may be formed on a substrate by a method such as coating, Physical Vapor Deposition (PVD), or Chemical Vapor Deposition (CVD). . Wherein, PVD comprises: physical Deposition methods such as magnetron sputtering or thermal evaporation, and CVD includes chemical Deposition methods such as Plasma Enhanced Chemical Vapor Deposition (PECVD). After that, the conductive material layer may be processed by a single patterning process to obtain the plurality of first electrode stripes. The one-time composition process comprises the following steps: photoresist coating, exposure, development, etching and photoresist stripping. The processing of the conductive material layer by adopting the one-step composition process comprises the following steps: coating a layer of photoresist on the conductive material layer; then, exposing the photoresist by using a mask plate to form an exposure area and a non-exposure area on the photoresist; then, a developing process is adopted for processing, so that the photoresist in one area of the exposure area and the non-exposure area is removed, and the photoresist in the other area is reserved; etching the area which is not covered by the photoresist on the conductive material layer; and stripping the photoresist on the conductive material layer after the etching is finished to obtain a plurality of first electrode strips. The photoresist may be a positive photoresist or a negative photoresist. If the photoresist is a positive photoresist, removing the photoresist in the exposure area and keeping the photoresist in the non-exposure area after the developing process; if the photoresist is a negative photoresist, the photoresist in the non-exposed region is removed and the photoresist in the exposed region remains after the above-described development process.
After the plurality of first conductive strips are formed on the substrate, the insulating layer 06 as shown in fig. 17 is formed on the substrate on which the plurality of first conductive strips are formed.

Alternatively, the thickness of the sealing structure in the direction away from the substrate base plate is larger than the shortest distance from the surface of the conductor block away from the substrate base plate to the surface of the side of the substrate base plate on which the conductor block is provided.

It can be seen from fig. 20 that the sealing structure 08 is annular and surrounds the region of the substrate base plate 01 where the plurality of conductor blocks 03 are arranged, wherein the thickness H1 of the sealing structure 08 in the direction away from the substrate base plate 01 is greater than the shortest distance H2 from the surface of the conductor block 03 remote from the substrate base plate to the surface of the substrate base plate on the side where the conductor block is arranged.
For example, the method of forming the insulating layer in step 1502 may be adopted to form a magnetic film layer 04 as shown in fig. 21 on the flexible substrate, where the magnetic film layer includes a plurality of magnetic stripes 041, and the plurality of magnetic stripes 041 may be arranged at intervals in a certain direction.
For example, in step 1507, a plurality of second electrode stripes 052 that are located at the same layer as the plurality of magnetic stripes 041 as shown in fig. 22 need to be formed on the flexible substrate 02, and the plurality of second electrode stripes 052 and the plurality of magnetic stripes 041 are arranged alternately. Alternatively, the width of second electrode strip 052 may be smaller than that of magnetic strip 041, and of course, the width of second electrode strip 052 may also be greater than or equal to that of magnetic strip 041, which is not limited in this embodiment of the present invention.
After the base substrate and the flexible substrate are arranged to face each other, the braille display panel shown in fig. 4 can be obtained. The conductor blocks, the touch electrode layer and the magnetic film layer are all located between the substrate base plate and the flexible base plate, and the conductor blocks and the magnetic film layer are spaced in the direction from the substrate base plate to the flexible base plate.
