Due to the adoption of the magnetic touch mode, the manufacturing process of the display screen is relatively simple, the cost is lower, the function is practical, and the display screen is completely free from the influence of self luminescence and natural light of the display screen; in addition, the Hall sensing modules and the light-emitting units can be simultaneously arranged on the substrate to form the display module, and the display module can be arranged in a one-to-one matrix manner, so that the display module can be spliced to form a display screen with 2K, 4K and 8K resolution, and the screen touch function can be realized without manufacturing an infrared sensing frame, so that the display device can get rid of the size limitation of the traditional frame type infrared sensing, can be spliced into any size by using the modules, can support various special-shaped screens such as an arc screen and the like to use, and supports multi-point touch; when an oversized display screen (such as the side length exceeding 10 meters) is applied, the signal is very stable, and the user experience is improved.
As shown in fig. 4, the sensing module 121 is a hall IC, a plurality of hall ICs are disposed in a display screen area of the display device 10, and are arranged in a one-to-one matrix with a plurality of corresponding light emitting units 122 to form a hall IC matrix (i.e., a display matrix) 13, and a single hall IC is responsible for sensing the magnetic field intensity at the light emitting unit corresponding to the hall IC.
As shown in FIG. 9, the coordinates of the light emitting unit are (x, y) (x row and y column of the display device), and the intensity of the magnetic field induced by the Hall IC corresponding to the coordinates is B (unit: Tesla, symbol: T). According to the Hall sensing principle: a control current I is conducted to two ends of a semiconductor slice, a uniform magnetic field with the magnetic induction intensity of B is applied to the vertical direction of the slice, and then a Hall voltage with the potential difference of U is generated in the direction vertical to the current and the magnetic field. The Hall voltage has the following calculation formula:
U＝KIB/d
in the formula, U is a hall voltage, K is a hall coefficient constant, and d is a conductor thickness constant.
According to the above calculation formula, when the hall IC is energized with a fixed current I, the hall voltage U is proportional to the magnetic field strength B. When the display device works, the hall IC matrices are all energized with a fixed current I, when a user touches the surface of the display device 10 (i.e., the surface of a display screen) with the pen tip 24 of the touch screen device 20 (as shown in fig. 6), as the pen tip 24 presses, the elastic structure 23 of the touch screen device 20 compresses, the distance between the permanent magnet 22 and the hall IC decreases, the number of magnetic induction lines of the permanent magnet 22 passing through a single hall IC increases, the vertical magnetic field strength B on the surface of the hall IC gradually increases, and the hall voltage U sensed by the hall IC increases in a direct ratio (as shown in fig. 7).
As shown in fig. 8, when the pen tip 24 of the touch screen device 20 is located at a distance h directly above the position of the 1# hall IC, due to the fact that the magnetic induction line density of the permanent magnet 22 which diverges towards the periphery in the vertical direction decreases, when h remains unchanged, the magnetic field strength of the 2# hall IC in the vertical direction is decreased with the increase of a (a is the distance between the two light-emitting units), the hall voltage U induced by the 2# hall IC is decreased with the increase of a, and when the hall IC matrix is arranged in the display device 10 (as shown in fig. 9), the hall voltages U of (1,1) (row 1, column 1), and (row 1,2) (column 1, column 2) … (x, y) (row x, column y) are respectively collected, and a three-dimensional model is built by using the group of data (as shown in fig. 10).
Fig. 10 is a three-dimensional coordinate system constructed by taking the row in fig. 9 as the x axis and the column as the y axis and taking the hall voltage value U of the corresponding point as the z axis. In the three-dimensional model of fig. 10, the local peak shape represents that the magnetic field intensity is increased, the local peak value represents that the magnetic field intensity is strongest at the local peak value, and when the local hall voltage value exceeds 1.25V, the electromagnetic interference can be eliminated, and the approach of the magnet is determined. And the coordinate (x, y) corresponding to the local peak is the closest distance between the screen surface and the touch screen device, namely the pen-down position of the touch screen device, and when a plurality of local peaks appear at different positions, the local peaks represent that a plurality of magnets are close to each other at different positions, and the local peaks represent that a plurality of touch screen devices write on the screen surface at the same time.
In an embodiment, the processing module is disposed inside the display device 10, and configured to control the display matrix 13 to perform an interaction operation corresponding to a preset interaction rule according to the sensing data of the sensing module 121 and according to the preset interaction rule.

The display module is used for sensing touch operation of the touch screen device on a display screen formed by the display matrix. The processing module is arranged in the display device and used for processing the touch operation according to a preset interaction rule according to the touch operation, sensed by the display module, of the touch screen device on the display screen and controlling the display matrix to carry out interaction operation agreed corresponding to the preset interaction rule.

Through the above detection data, different touch types are set according to different hall voltage value ranges, and the specific setting is as follows:
when the peak value of the Hall voltage is lower than 0.5V, the touch screen device is far from the surface of the display screen (50 mm);
when the Hall voltage peak interval is 0.5V-1V, the touch screen device is close to the surface (1-50 mm) of the display screen, and a first touch type is defined;

The specific implementation process is as follows:
when the touch screen device is pressed to a display screen surface coordinate (60,60) from a position close to the display screen surface to the maximum extent, the Hall sensing voltage at the coordinate (60,60) is the maximum value (namely, a peak value U) in the whole Hall IC matrix at the moment, the peak value is sequentially increased from 0.5V (Umin) to 2V (Umax), and the screen displays a black dot with a radius R (which is in direct proportion to the peak value) which is continuously increased by taking (60,60) as a center in the process.
When Bmax is 6(mm) and the minimum writing width Bmin is a, the formula can be obtained:
Bmax＝Umax×k+b→6＝2k+b
Bmin＝Umin×k+b→1.2＝0.5k+b
b-3.2 × U-0.4 can be obtained from the above formula.
R ═ B/2 (R may be decimal)
The system will calculate the coordinates of the light emitting cells within a circle of radius R centered on the coordinate point (60,60) and set the color of these light emitting cells to black.
When the touch point of the touch screen device is in the situation shown in fig. 13, there may be multiple coordinates corresponding to the peak of the hall matrix, and the coordinates are all in an adjacent relationship, and the system will average the coordinates, that is, the hall matrix coordinate point (X, Y) — (((X1+ X2+. Xn) ÷ n), ((Y1+ Y2+. Yn) ÷ n)).
When the circle center is (X, Y), R is decimal, and the sum of X and R is rounded because the coordinate point of decimal does not exist on the screen.
When the display screen is in a writing mode: in the sliding process of the touch screen device on the surface of the display screen, the Hall IC matrix calculates the coordinates of a contact point according to a Hall voltage peak value U acquired in real time, and the light-emitting unit with the radius within the range of R is set to be black by taking the coordinate point as the circle center, so that the touch writing function of the display screen is realized.
When the display screen is in the erasing mode: in the sliding process of the touch screen device on the surface of a display screen, the Hall IC matrix calculates the coordinates of a contact point according to a Hall voltage peak value U acquired in real time, and the light-emitting unit with the radius within the range of R is set to be an original picture by taking the coordinate point as the circle center, so that the function of the display screen eraser is realized.
when the touch screen device is pressed to the surface of the display screen from the position close to the surface of the display screen to the maximum extent, the Hall matrix sequentially detects the touch type A → B → C → D;
when the touch screen device is pressed to the position close to the surface of the display screen from the maximum degree, the Hall matrix sequentially detects the touch type D → C → B → A;
one deep click: namely, from the step of pressing away from the display screen to the maximum extent and then lifting away from the display screen, the Hall matrix sequentially detects A → B → C → D → C → B → A, and the fluctuation range of the coordinate (x, y) corresponding to the Hall voltage peak value in the process does not exceed +/-1.
The double-click operation defines: two deep clicks are completed within 1.5 seconds, and the fluctuation range of coordinates (x, y) corresponding to the Hall voltage peak value in the process is not more than +/-3.
Mode switching: when the display screen is in the writing process, the touch system can switch the writing pen and the eraser by double-click operation.
Confirming opening: when the display screen displays the content with the application icon or the file and the folder, the open application or file operation can be executed by using the double-click operation.
Content movement: and after the touch screen device is deeply clicked once, the touch screen device is completely pressed to the surface of the display screen again without being lifted, and at the moment, the touch point of the touch screen device is moved, so that the content of the display screen can be controlled to move a window. If the application, file icon or picture and video display window exists in the initial clicking position, the icon or window moves along with the contact in real time, and when the touch screen device is lifted, the icon or window stops at the contact position when the touch screen device is lifted.
