Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are intended to be within the scope of the present application.
The embodiment of the application provides a touch display device 100. Fig. 1 is a schematic structural diagram of a touch display device according to an embodiment of the present disclosure; fig. 2 is a schematic structural diagram of a frame structure according to an embodiment of the present application.
Referring to fig. 1 and fig. 2, a touch display device 100 according to an embodiment of the present disclosure includes a frame structure 1000, an infrared transceiver 3000, a display module, and a back plate 6000.
In one embodiment, as shown in fig. 1, the touch display device 100 includes a main body 1100 and a filter 1200, which are integrally formed, the main body 1100 has a receiving space 1110 inside, and the filter 1200 is capable of transmitting infrared light signals; an infrared transceiver 3000 disposed in the accommodating space 1110, wherein the infrared transceiver 3000 is disposed toward the optical filter 1200; a back plate 6000 connected to the body 1100; and the display module is clamped in a clamping space formed between the back plate 6000 and the light filtering part 1200.
In one example, the frame structure 1000 is formed by injection molding of a plastic material. The main body 1100 and the filter 1200 of the frame structure 1000 may be made of the same plastic material by injection molding. For example, the main body 1100 and the filter of the bezel structure 1000 are both injection molded from PMMA, but in order to avoid interference of infrared signals other than the infrared signals emitted by the infrared emitter, an ink layer 1140 covers the outer surface of the main body 1100, and the ink layer 1140 can absorb the infrared signals.
In an example, the main body 1100 and the filter 1200 of the frame structure 1000 may be formed by injection molding of two plastic materials. For example, since the optical filter portion 1200 needs to perform the optical filtering function, the color and material of the optical filter portion 1200 may be different from those of the main body portion 1100, for example, the color of the optical filter portion 1200 may be deep red, the color of the main body portion 1100 may be black, the material of the optical filter portion 1200 may be PMMA, and the material of the main body portion 1100 may be ABS.
In this embodiment, the frame structure 1000 is formed by injection molding of a plastic material, which can save cost compared with an aluminum frame; on the other hand, the frame structure 1000 made of plastic material enables the weight of the touch display device 100 as a whole to be lighter, the use to be more convenient and the experience to be better.
In addition, since the frame structure 1000 of the embodiment of the present application has the main body 1100 and the light filtering portion 1200 that are integrally formed, it is not necessary to install the light filtering strip on the frame structure 1000, and the step of assembling the frame structure 1000 and the light filtering strip is omitted to some extent, which saves man-hours and labor costs, and it is not necessary to worry about reduction of the yield of production due to a gap between the light filtering strip and the frame structure. In addition, since the frame structure 1000 of the embodiment of the present application does not need to be provided with the light filtering strip, the touch height of the touch display device 100 is increased without considering the fastening structure between the light filtering strip and the frame structure 1000, and the height of the touch display device 100 can be effectively reduced, so as to achieve the effect of ultra-thin touch. Meanwhile, the lower touch height enables the touch performance of the touch display device 100 to be better, and the touch display device is closer to the experience of writing on paper, so that better writing experience is brought to a user.
In one example, the frame structure 1000 may be a closed square structure formed by connecting two frames in a long strip shape end to end. The frame structure 1000 of the spliced closed square structure is simple to produce and manufacture, and can be flexibly assembled into frame structures 1000 of different shapes according to the requirement of the appearance of the touch display device 100.
For example, the frame structure may be a ring structure having a shape of a rectangle, a circle, an ellipse, a polygon, etc., according to the appearance of the touch display device 100.
In one example, the infrared transceiver 3000 includes: an infrared receiver for receiving an infrared light signal; and the infrared transmitter is used for transmitting an infrared light signal. In this embodiment, after the infrared transmitter disposed on one side of the frame structure 1000 of the closed square structure transmits the infrared light signals, the infrared light signals are transmitted to the outside after being filtered by the filter 1200, and meanwhile, the infrared light signals are transmitted to the infrared receiver disposed on the opposite side of the frame structure 1000 of the closed square structure after being filtered by the filter 1200 disposed on the opposite side of the frame structure 1000 of the closed square structure. When a user triggers a touch function on the touch display device 100, the infrared light signal is blocked, so that the infrared light signal on a point path of the display module touched by the user cannot be transmitted to the infrared receiver, and the coordinate of the point is accurately calculated through analysis and calculation, thereby realizing the touch function of the touch display device 100.
In one example, the back plate 6000 is connected to the frame structure 1000 of the closed square structure by fasteners. Further the fasteners may be in-line screws, cross screws or bolts etc.
In an example, in order to avoid the display module assembly by backplate 6000 not tight enough with the frame structure 1000 joint of the square structure of closed, when easily becoming flexible, can use insulating bonding agent further fixed display module assembly in the junction between display module assembly and backplate 6000. In order to further improve the bonding effect, textures can be arranged at the bonding position of the display module, and the contact area between the display module and the insulating adhesive is increased.
In one embodiment, corner connectors (not shown) are further disposed on the frame structure 1000, and the corner connectors are connected to corners of the frame structure 1000 in a closed square structure to reinforce the strength of the corners of the frame structure 1000.
In this embodiment, the frame structure 1000 is a closed square structure formed by connecting two long-strip-shaped frames end to end, but the frame structure 1000 of this spliced closed square structure has insufficient strength at the connected corners and is easy to separate. Therefore, corner connecting pieces need to be installed at the splicing corners of the frame structure 1000 with the closed square structure and are fixedly connected through screws, so that the splicing positions of the frame structure 1000 with the closed square structure are connected more stably.
In one embodiment, as shown in fig. 1, a clamping portion 1111 is disposed in the accommodating space 1110, the clamping portion 1111 is used for clamping the infrared PCB 2000 disposed in the accommodating space 1110, and the infrared transceiver 3000 is connected to the infrared PCB 2000.
Specifically, the two opposite sides of the inner wall of the accommodating space 1110 are respectively formed with a strip-shaped groove extending along the length direction of the filter 1200, and a clamping portion 1111 is formed between the two strip-shaped grooves. Further, the inner walls of the accommodating spaces 1110 are recessed inward along the length direction of the filter 1200 to form strip-shaped grooves.
In other embodiments, two protrusions parallel to each other are disposed on the inner wall of the accommodating space 1110 along the length direction of the filter 1200, and a strip-shaped groove is formed between the two protrusions parallel to each other. Specifically, the protrusion and the main body 1100 are integrally formed, so that the protrusion and the accommodating space 1110 in the main body 1100 form a more stable structure, and the bearing capacity of the strip-shaped groove is increased.
The two strip-shaped grooves are respectively clamped at two ends of the infrared PCB board 2000. Further, the infrared PCB 2000 is in clearance fit with the two strip-shaped grooves, so that errors generated due to production can be compensated, and the infrared PCB 2000 can be mounted between the strip-shaped grooves more simply and conveniently.
It is understood that, in other embodiments, the infrared PCB 2000 may also have an interference fit with the strip-shaped groove. The interference fit may enable the infrared PCB 2000 to be more firmly fixed to the bezel structure 1000.
In this embodiment, the infrared PCB 2000 is electrically connected to the infrared transceiver 3000, the infrared PCB 2000 provides electric energy for the infrared transceiver 3000 to work, and the infrared PCB 2000 can also analyze and calculate the infrared light signal, so that the infrared transceiver 3000 can send or receive the infrared light signal and the coordinates of the shielded point of the infrared light signal on the display module. Simultaneously, the infrared PCB 2000 is clamped through the strip-shaped groove, so that the error of the calculated coordinates of the shielded points caused by shaking of the infrared PCB 2000 is avoided.
In one embodiment, the main body 1100 further defines a portion of the receiving groove 1130 for receiving the backing plate 6000, and the notch of the receiving groove 1130 faces away from the main body 1100.

Therefore, the accommodating groove 1130 is formed on the main body 1100 adjacent to the filter portion 1200, so that the influence of the frame structure 1000 caused by expansion and contraction due to heat and cold can be reduced. In addition, the notch of the receiving groove 1130 faces away from the main body 1100, so that a part of the structure of the back plate 6000 can be inserted into the receiving groove 1130 through the notch of the receiving groove 1130.
In one embodiment, as shown in fig. 2, a boss 1131 is disposed at the notch of the receiving groove 1130, and a clamping gap for clamping a portion of the back plate 6000 is formed between the boss 1131 and the groove wall of the receiving groove 1130.
It should be noted that, as shown in fig. 2, an edge portion of the back plate 6000 extends upward to form a folded edge 6100, and the folded edge 6100 extends into the receiving groove 1130 through the notch of the receiving groove 1130, so as to further secure the frame structure 1000 and the back plate 6000. Therefore, the boss 1131 is disposed on the notch of the receiving groove 1130, and the boss 1131 and the groove wall of the receiving groove 1130 are matched to clamp the folded edge 6100, so that the back plate 6000 can be more stably fixed to the frame structure 1000.
