[0021] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present.
[0023] Embodiment 1: Please refer to Figures 1 - 14 , a multi-touch display panel in this embodiment includes a display panel body. The display panel includes a light guide plate 1 and a touch panel assembly 2 that are connected to each other. The touch panel assembly 2 is any one of an electromagnetic induction panel 21, a capacitive induction panel 22, and a composite induction panel 23.
[0024] Specifically, the composite induction panel 23 is an electromagnetic-capacitive combined induction panel.
[0025] Furthermore, the touch panel assembly 2 is disposed on the front or back of the light guide plate 1.
[0026] It should be noted that the touch panel assembly 2 can be flexibly disposed on the front or back of the light guide plate 1 to meet the usage requirements in different application scenarios.
[0027] Even further, the connection distribution method of the touch panel assembly 2 includes any one of a first connection distribution method, a second connection distribution method, a third connection distribution method, a fourth connection distribution method, a fifth connection distribution method, and a sixth connection distribution method; As Figure 2 shown, the first connection distribution method is that the electromagnetic induction panel 21 and the light guide plate 1 are connected in sequence; Specifically, in the first connection distribution method, the electromagnetic induction panel 21 is located in front of the light guide plate 1, which can preferentially receive electromagnetic pen signals, reduce interference with the electromagnetic field, and improve the detection accuracy of pen pressure and tilt angle.
[0028] As Figure 3 shown, the second connection distribution method is that the capacitive induction panel 22 and the light guide plate 1 are connected in sequence; Specifically, in the second connection distribution method, the capacitive induction panel 22 is located in front of the light guide plate 1, making the capacitive induction panel 22 close to the user operation surface, enhancing the sensitivity and response speed of finger touch, and at the same time avoiding interference of electromagnetic pen signals with capacitive touch.
[0029] As Figure 4 shown, the third connection distribution method is that the composite induction panel 23 and the light guide plate 1 are connected in sequence; Specifically, in the third connection distribution method, the composite induction panel 23 is located in front of the light guide plate 1. In this distribution method, two signals are isolated through a hierarchical circuit design, supporting synchronous operation of the electromagnetic pen and the finger, and reducing hardware redundancy.
[0030] As Figure 5 shown, in the fourth connection distribution method, the light guide plate 1 and the electromagnetic induction panel 21 are connected in sequence; Specifically, in the fourth connection distribution method, the electromagnetic induction panel 21 is located behind the light guide plate 1. By using the light guide plate 1 to isolate light source interference, the thickness of the multi-touch display panel can be reduced, facilitating the multi-touch display panel in ultra-thin devices.
[0031] As Figure 6 shown, in the fifth connection distribution method, the light guide plate 1 and the capacitive induction panel 22 are connected in sequence; Specifically, in the fifth connection distribution method, the capacitive induction panel 22 is located behind the light guide plate 1, which can reduce the influence of scratches or stains on the surface of the multi-touch display panel on the touch accuracy and improve the durability.
[0032] As Figure 7 shown, in the sixth connection distribution method, the light guide plate 1 and the composite induction panel 23 are connected in sequence.
[0033] Specifically, in the sixth connection distribution method, the composite induction panel 23 is located behind the light guide plate 1. In this method, by combining the light uniform distribution characteristics of the light guide plate 1, the touch signal stability is optimized, and at the same time, the thickness of the multi-touch display panel is reduced.
[0034] Furthermore, the number of the touch panel assemblies 2 is two, and the touch panel assembly 2 is any one of the electromagnetic induction panel 21 and the capacitive induction panel 22. The combined distribution methods of the two touch panel assemblies 2 include any one of the first combined distribution method, the second combined distribution method, the third combined distribution method, and the fourth combined distribution method; As Figure 8 shown, in the first combined distribution method, the electromagnetic induction panel 21, the capacitive induction panel 22 and the light guide plate 1 are connected in sequence; Specifically, in the first combined distribution method, the electromagnetic induction panel 21 and the capacitive induction panel 22 are separately arranged in front and behind the light guide plate 1. In this method, the electromagnetic induction panel 21 can preferentially capture the pen signal in the front, and the capacitive induction panel 22 responds to finger touch in the back. By physically isolating the electromagnetic and capacitive signals through layering, crosstalk is eliminated.
[0035] As Figure 9 shown, in the second combined distribution method, the capacitive induction panel 22, the electromagnetic induction panel 21 and the light guide plate 1 are connected in sequence; Specifically, in the second combined distribution method, the capacitive induction panel 22 and the electromagnetic induction panel 21 are arranged one in front of the other in front of the light guide plate 1. In this method, the capacitive induction panel 22 can be used to optimize finger touch in the front, and the electromagnetic induction panel 21 can be used to avoid light source interference in the back, so as to achieve high-precision capture of handwriting details, such as the tip of a pen.
[0036] As Figure 10 shown, in the third combined distribution method, the light guide plate 1, the electromagnetic induction panel 21 and the capacitive induction panel 22 are connected in sequence; Specifically, in the third combined distribution method, the electromagnetic induction panel 21 and the capacitive induction panel 22 are arranged one in front of the other behind the light guide plate 1, which can take into account both touch sensitivity and display effect.
[0037] As Figure 11 shown, in the fourth combined distribution method, the light guide plate 1, the capacitive induction panel 22 and the electromagnetic induction panel 21 are connected in sequence.
[0038] Specifically, in the fourth combined distribution method, the capacitive induction panel 22 and the electromagnetic induction panel 21 are arranged one in front of the other behind the light guide plate 1, with the capacitive induction panel 22 closer to the user operation surface in the front and the electromagnetic induction panel 21 reducing signal attenuation in the back, so as to achieve pen pressure sensitivity grading.
[0039] Furthermore, the number of the touch panel assemblies 2 is two, and the two touch panel assemblies 2 are symmetrically arranged on the front and back of the light guide plate 1. The touch panel assembly 2 can be either the electromagnetic induction panel 21 or the capacitive induction panel 22. The symmetrical distribution method of the two touch panel assemblies 2 includes any one of the first symmetrical distribution method and the second symmetrical distribution method; As Figure 12 shown, in the first symmetrical distribution method, the electromagnetic induction panel 21, the light guide plate 1 and the capacitive induction panel 22 are connected in sequence; Specifically, in the first symmetrical distribution method, the electromagnetic induction panel 21 and the capacitive induction panel 22 are arranged on the front and back sides of the light guide plate 1 respectively. Through the physical isolation of the light guide plate 1, signal interference is completely eliminated, supporting simultaneous operation of the electromagnetic pen and the finger without mutual influence.
[0040] As Figure 13 shown, in the second symmetrical distribution method, the capacitive induction panel 22, the light guide plate 1 and the electromagnetic induction panel 21 are connected in sequence.
[0041] Specifically, in the first symmetrical distribution method, the capacitive induction panel 22 and the electromagnetic induction panel 21 are arranged on the front and back sides of the light guide plate 1 respectively, optimizing handwriting details, such as tilt angle simulation, to achieve the integration of smooth writing and fast touch.
[0042] In summary, by flexibly arranging the electromagnetic induction panel 21, the capacitive induction panel 22 and the composite induction panel 23, electromagnetic pens and finger touches can be compatible, improving the usage effect.
[0043] Furthermore, as Figure 14 shown, a plurality of positioning grooves 4 are formed on the light guide plate 1, and corresponding positioning bumps 3 are arranged on the touch panel assembly 2. When the light guide plate 1 is connected to the touch panel assembly 2, the positioning bumps 3 are inserted into the positioning grooves 4.
[0044] It should be noted that in order to achieve high-precision positioning connection between the light guide plate 1 and the touch panel assembly 2, when the two are connected, positioning can be realized through the close cooperation between the positioning bumps 3 and the positioning grooves 4, thereby reducing the assembly error when the light guide plate 1 is connected to the touch panel assembly 2 and improving the yield rate.
[0045] Specifically, the cross-sectional shapes of the positioning bumps 3 and the positioning grooves 4 are both triangular, and the four positioning bumps 3 are distributed in a rectangle; in addition, in terms of the sizes of the positioning bumps 3 and the positioning grooves 4, the diameter of the positioning bumps 3 is 2-3 mm, and the height of the positioning bumps 3 is 1.5-2 mm; the diameter of the positioning grooves 4 is 2.2-3.2 mm, and the depth of the positioning grooves 4 is 1.8-2.3 mm.
[0046] It should be noted that when connecting the light guide plate 1 to the touch panel assembly 2, first apply transparent optical glue to the positioning bumps 3 or the positioning grooves 4, and then align the positioning bumps 3 with the positioning grooves 4 to connect the light guide plate 1 to the touch panel assembly 2. When connecting, a pressure of 5-10 N needs to be evenly applied to embed the positioning bumps 3 into the positioning grooves 4; the cooperation between the positioning bumps 3 and the positioning grooves 4 provides a clear physical positioning reference for the light guide plate 1 and the touch panel assembly 2. The operator only needs to insert the positioning bumps 3 on the touch panel assembly 2 into the positioning grooves 4 on the light guide plate 1 to complete the preliminary alignment. This method improves the positioning accuracy compared with the traditional manual alignment and assembly method, greatly reduces the adjustment time, and significantly improves the assembly efficiency and the yield rate. In addition, under the cooperation of the positioning bumps 3 and the positioning grooves 4 distributed in a rectangle, the offset of the touch panel assembly 2 is restricted, avoiding problems such as touch signal crosstalk or uneven backlight caused by misalignment, and further improving the yield rate.
[0047] It should also be noted that the positioning grooves 4 on the light guide plate 1 are formed by laser engraving, and the positioning bumps 3 on the touch panel assembly 2 are injection molded from a polymer material; in addition, through the shapes of the positioning bumps 3 and the positioning grooves 4, the unique assembly direction can also be restricted to avoid misassembly caused by reverse installation by workers.
[0048] In a specific embodiment, when connecting and assembling the light guide plate 1 of different sizes with the touch panel assembly 2, the positioning bumps 3 and positioning grooves 4 of corresponding sizes should be reasonably selected according to their thermal expansion characteristics. The corresponding sizes of the positioning bumps 3 and positioning grooves 4 can be accurately calculated and determined by a thermodynamic analysis model, the finite element analysis method, or the experimental calibration method, based on the specific sizes and thermal expansion coefficients of the light guide plate 1 and the touch panel assembly 2.
[0049] Specifically, the diameter of the positioning bump 3 is obtained through the following calculation formula according to the size of the light guide plate: ; In the formula: is the length of the light guide plate; is the proportionality coefficient.
[0050] It should be noted that the proportionality coefficient is obtained based on actual engineering experience according to the size of the light guide plate and is well-known to those skilled in the art. It will not be described in this embodiment. In addition, the diameter of the positioning bump 3 needs to be rounded.
[0051] Specifically, the diameter of the positioning groove 4 is obtained through the following calculation formula: ; ; In the formula: is the thermal expansion difference; is the angle of the triangular cross-section of the positioning groove 4; is the thermal expansion coefficient of the light guide plate; is the thermal expansion coefficient of the touch panel; is the temperature value; It should be noted that the angle of the triangular cross-section of the positioning bump 3 and the positioning groove 4 is 60°. The thermal expansion coefficient of the light guide plate, the thermal expansion coefficient of the touch panel, and the temperature value are well-known to those skilled in the art and will not be described in this embodiment.
[0052] Specifically, the height of the positioning bump 3 is obtained through the following calculation formula: ; In the formula: is the proportionality coefficient; is the thickness of the light guide plate.
[0053] It should be noted that the proportionality coefficient is obtained according to the size of the light guide plate, and the thickness of the light guide plate can be measured by a measuring instrument before assembly.
[0054] Specifically, the depth of the positioning groove 4 is obtained through the following calculation formula: ; In the formula: is the compensation value.
[0055] It should be noted that the supplementary value can be the tolerance value.
[0056] It should also be noted that since the cross-sectional shapes of the positioning bump 3 and the positioning groove 4 are triangular, after being heated, the angle of the triangular cross-section of the positioning groove 4 will affect the expansion direction. Therefore, when determining the diameter and depth of the positioning groove 4, the expansion difference needs to be compensated to avoid jamming.
[0057] For example, when the size of the light guide plate 1 is 200×150mm, 300×200mm, 450×300mm, ……, the diameters of the positioning bumps 3 are 2.0mm, 2.2mm, 2.5mm, …… respectively, the diameters of the positioning grooves 4 are 2.1mm, 2.35mm, 2.7mm, ……, the heights of the positioning bumps 3 are 0.6mm, 0.8mm, 1.0mm, ……, and the depths of the positioning grooves 4 are 0.8mm, 1.0mm, 1.2mm, …….
[0058] It can be known that by adjusting the parameters of the positioning bump 3 and the positioning groove 4 according to the sizes of the light guide plate 1 and the touch panel assembly 2, it is possible to avoid the situation where the positioning bump 3 and the positioning groove 4 are jammed due to thermal expansion, resulting in a reduction in the yield rate.
[0059] It can be understood that when the light guide plate 1 and the touch panel assembly 2 are connected, the heat imparted in the previous process will remain on both of them, causing the positioning bump 3 and the positioning groove 4 to experience thermal expansion.
[0060] Embodiment 2: A display in this embodiment includes a multi-touch display panel as in Embodiment 1. The display further includes a top cover, a touch sensing panel, a backlight module, a control board, a reflector and the top cover, and the reflector is connected to the display panel body.
[0061] Furthermore, a shielding layer is provided on the reflector, and the shielding layer material is any one of an absorbing material, a silicon steel sheet, and a transparent material interference shielding film.
[0062] Embodiment 3: An integration process of a multi-touch display panel in this embodiment is applied to a multi-touch display panel as in Embodiment 1, and includes a display panel body obtained by thermally pressing the light guide plate 1 and the touch panel assembly 2.
[0063] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
