[0028] With the progress and development of science and technology, multimedia all-in-one computers have been widely used in teaching industries or conference rooms and other occasions. Among them, larger multimedia all-in-one computers usually use spliced ​​display screens. The spliced ​​display screen is formed by splicing multiple light board units, and each light board unit is provided with an independent small film on its surface. However, after the light board units are spliced, a seam is likely to appear between two adjacent small films, making the surface of the display screen uneven. For multimedia all-in-one computers with touch functions, the seam will affect the smoothness of touch and writing, and may even accidentally lift the edge of the small film during writing, further affecting the use of the multimedia all-in-one computer.

[0029] Reference Figures 1 to 7 The first aspect of the present application provides a touch display screen, which includes a display module 1, a frame 2 and an infrared touch component 3. The display module 1 includes a plurality of light board units 11 and a protective film 12, the plurality of light board units 11 are arranged in a matrix, any two adjacent light board units 11 abut against each other, the display surfaces 111 of the plurality of light board units 11 are in the same plane, the protective film 12 covers the display surfaces 111 of all light board units 11, and the protective film 12 includes a protective side 121 away from the display surface 111; the frame 2, the frame 2 is enclosed in the display module 1; the infrared touch component 3, which is arranged in the frame 2, the infrared touch component 3 includes a transmitting end 31 and a receiving end, and the transmitting end 31 and the receiving end protrude from the protective side 121.

[0030] According to the above structure, the touch screen involved in the present application can use a single protective film 12, which is different from the traditional splicing type display screen which needs to splice multiple small films, thus resulting in the splicing gaps between the small films. In this way, the flatness of the touch screen involved in the utility model is higher, and it can have a better display effect. In addition, the infrared touch component 3 is installed on the frame 2, which will not affect the display surface 111. Therefore, the touch screen involved in the utility model has a better display effect, and it can also be smoother and more natural when performing touch and writing operations.

[0031] Reference Figure 1 and Figure 2 Specifically, the transmitting end 31 and the receiving end protrude from the protection side 121. It can be understood that the transmitting end 31 and the receiving end are located on the side of the protection side 121 away from the light board unit 11, and there is a distance between the transmitting end 31 and the receiving end. Thus, a complete infrared ray transmitting and receiving path can be formed between the transmitting end 31 and the receiving end.

[0032] As an embodiment, the transmitting end 31 and the receiving end protrude from the protective side 121, and the distance protruding from the protective side 121 is 3mm-5mm; the distance protruding from the protective side 121 of the transmitting end 31 and the receiving end is consistent. Specifically, the distance protruding from the protective side 121 of the transmitting end 31 and the receiving end is not less than 3mm, which is conducive to the emission and reception of infrared rays. However, the distance protruding from the protective side 121 of the transmitting end 31 and the receiving end does not exceed 5mm, so that when the user touches the screen, the emission and reception paths of infrared rays will not be intercepted prematurely by fingers or pen tips, thereby reducing the possibility of accidental touches.

[0033] Reference Figure 3As an embodiment, the frame 2 includes two first mounting positions parallel to the first direction and spaced apart, and the frame 2 also includes two second mounting positions parallel to the second direction and spaced apart, and the first direction is perpendicular to the second direction; the infrared touch component 3 includes a plurality of first infrared transmitters and a plurality of first infrared receivers, and the two first mounting positions are respectively installed with the first infrared transmitters and the first infrared receivers; the infrared touch component 3 includes a plurality of second infrared transmitters and a plurality of second infrared receivers, and the two second mounting positions are respectively installed with the second infrared transmitters and the second infrared receivers. Specifically, it can be understood that the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver are respectively arranged on the four borders of the square frame 2. Thus, on the plane of the protruding protection side 121, an infrared grating network with infrared beams crisscrossing can be formed between the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver, and the infrared grating network divides the screen into multiple areas, and each area corresponds to the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver. When the user touches the protective side 121 with a finger or a writing pen, the finger or the writing pen will block the infrared rays emitted by the corresponding first infrared transmitter and the second infrared transmitter, and the corresponding first infrared receiver and the second infrared receiver will not detect the infrared light signal, thereby determining the location of the touch point.

[0034] Specifically, multiple first infrared transmitters are spaced and evenly arranged, multiple first infrared receivers are spaced and evenly arranged; multiple second infrared transmitters are spaced and evenly arranged, multiple second infrared receivers are spaced and evenly arranged. Thus, the grids of the infrared grating network can be evenly distributed on the protection side 121, so that the touch display screen can have more accurate touch position detection. When the user touches the screen, the system can automatically determine the touch position based on the blocked infrared light, and the uniform grid layout helps to reduce errors.

[0035] It can be understood that the transmitting end 31 of the infrared touch component 3 is the infrared transmitting tube of the first infrared transmitter and the infrared transmitting tube of the second infrared transmitter, and the receiving end of the infrared touch component 3 is the infrared receiving tube of the first infrared receiver and the infrared receiving tube of the second infrared receiver.

[0036] As an embodiment, the thickness of the protective film 12 ranges from 80 microns to 150 microns. According to this setting, the thickness of the protective film 12 can better resist scratches and wear and tear, and protect the surface of the touch display screen from damage. And it can have good color reproduction and clarity, and prevent screen degradation due to external factors. In addition, the thickness of the protective film 12 can provide necessary protection and have good cost-effectiveness. Therefore, by adopting such a thickness parameter, while achieving a good display effect, it meets the requirements of operating performance and cost control.

[0037] Reference Figure 4 As an embodiment, the protective film 12 includes: an AG layer 122, a base layer 123 and a back adhesive layer 124; wherein the back adhesive layer 124 is bonded to the surface of the display surface 111, and the base layer 123 is sandwiched between the AG layer 122 and the back adhesive layer 124. Specifically, the back adhesive layer 124 is bonded to the surface of the display surface 111 of the light board unit 11 to fix the protective film 12 to the light board unit 11. The base layer 123 is sandwiched between the AG layer 122 and the back adhesive layer 124 to support the AG layer 122 and the back adhesive layer 124, thereby improving the structural stability of the protective film 12. Therefore, the protective film 12 adopts the above composite film layer structure, which can balance the optics and tensile force of the protective film 12, effectively solve the attachment process and ensure the display effect.

[0038] As an embodiment, the thickness of the AG layer 122 ranges from 5 microns to 10 microns, the thickness of the base layer 123 ranges from 20 microns to 100 microns, and the thickness of the adhesive layer 124 ranges from 30 microns to 120 microns. The thickness of the AG layer 122 can range from 5 microns to 10 microns; the thickness of the base layer 123 can range from 20 microns to 100 microns; and the thickness of the adhesive layer 124 can range from 30 microns to 120 microns.

[0039] Reference Figure 5 and Figure 6 As an embodiment, the touch screen further includes a colloid 4; the light board unit 11 further includes a display back side arranged opposite to the display surface 111, the colloid 4 is located on the display back side of the light board unit 11, and any two adjacent light board units 11 are connected through the colloid 4. Therefore, the colloid 4 is located on the display back side of the light board unit 11, which will not affect the display surface 111, and the connection through the colloid 4 can simplify the assembly process of the light board unit 11, the connection structure is simple, and it can also avoid the light board unit 11 causing gaps between adjacent light board units 11 due to the complex connection structure.

[0040] Reference Figure 6As an embodiment, the colloid 4 includes a plurality of glue segments 41, and at least two glue segments 41 are arranged between any two adjacent light board units 11. Specifically, it can be understood that glue is applied to multiple areas at the joint of the two light board units 11 so that the two adjacent light board units 11 can be connected and fixed. Therefore, the interval between the two glue segments 41 can save materials and reduce costs.

[0041] As an embodiment, the colloid 4 includes a first adhesive strip and a second adhesive strip, the first adhesive strip extends along the length direction of the display surface 111 board to connect multiple light board units 11, and the second adhesive strip extends along the width direction of the display surface 111 board to connect multiple light board units 11. In this way, the edges of two adjacent light board units 11 can be completely bonded by the first adhesive strip or the second adhesive strip, and the connection between the two adjacent light board units 11 is more firmly. Among them, the structure of the first adhesive strip and the second adhesive strip can be understood as continuous glue coating. In the process of gluing, at the connection between two adjacent light board units 11, glue can be continuously applied along the length direction of the Micro LED display surface 111 board, or glue can be continuously applied along the width direction of the Micro LED display surface 111 board, which is more convenient to operate and more efficient in gluing.

[0042] Reference Figure 7 As an embodiment, the frame 2 is provided with a mounting groove 21, and the infrared touch component 3 is accommodated in the mounting groove 21 and connected to the inner wall of the mounting groove 21. Therefore, the setting of the mounting groove 21 can make the infrared touch component 3 more concealed, so that the infrared touch component 3 does not protrude from the frame 2, thereby reducing the damage to the infrared touch component 3 caused by external impact, and can also make the appearance of the touch display screen more neat and beautiful. Among them, the part of the frame 2 corresponding to the transmitting end 31 and the receiving end of the infrared touch component 3 can be made of a light-transmitting material to ensure the transmission of the infrared light beam.

[0043] A second aspect of the present application provides a display device, which includes the touch display screen mentioned above.

[0044] In summary, the touch screen involved in the present application can use a single protective film 12, which is different from the traditional spliced ​​display screen that needs to splice multiple small films, resulting in splicing gaps between the small films. In this way, the touch screen involved in the utility model has a higher flatness and can have a better display effect. In addition, the infrared touch component 3 is installed on the frame 2 and will not affect the display surface 111. Therefore, the touch screen involved in the utility model has a better display effect, and it can also be smoother and more natural when performing touch and writing operations.
