Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to a lamp tube structure and a touch screen component. Background Art

[0002] An infrared touch screen (i.e., a touch screen assembly) is a device that has infrared light-emitting diodes (hereinafter referred to as transmitting lamps) and infrared photosensitive diodes (hereinafter referred to as receiving lamps) arranged in a certain pattern around the display screen. The lamp structure (including transmitting lamps and receiving lamps) is a key component for the infrared touch screen to realize the touch function. The transmitting lamp can emit infrared light, and the receiving lamp can receive the infrared light and convert it into an electrical signal. The MCU (Microcontroller Unit, microcontroller unit or single-chip computer) can collect and process the electrical signal to obtain a collection signal. By detecting the change in the collection signal, it can be determined whether the infrared light emitted by the transmitting lamp is blocked by the touch object, thereby realizing the touch function.

[0003] Moreover, the infrared light emitted by each emitting lamp has a certain effective angle, and the emitting lamp can form effective light with each receiving lamp within the effective angle. Through the dense arrangement of emitting lamps and receiving lamps around the display screen, a dense optical network composed of a large number of effective lights can be formed in the display screen. Moreover, the density of the optical network depends on the size of the effective angle of each lamp, and the density of the optical network determines the performance effects such as the touch accuracy and the minimum recognition object of the infrared touch screen. In traditional technology, the lamp tube structure used in infrared touch screens is usually a vertical SMD lamp tube. The effective angle of this vertical SMD lamp tube is determined by the lens of the lamp tube structure, so that the effective angle of this lamp tube structure is the lamp tube angle of the lamp tube structure itself, and the lamp tube angle of the lamp tube structure itself is usually unchangeable. Therefore, the inability to increase the effective angle of the lamp tube structure is a problem in the current industry. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figure 1 and Figure 4 As shown, the utility model provides a lamp tube structure including a lamp tube unit, and the lamp tube unit may include one lamp tube or multiple (referring to two or more) lamp tubes, that is, the lamp tube structure may include one lamp tube or multiple lamp tubes.

[0048] Moreover, if Figure 1 , Figure 4 , Figure 5As shown, the lamp tube unit may include at least one inclined lamp tube 100, that is, at least one lamp tube in the lamp tube structure may be set as an inclined lamp tube 100 to increase the effective angle of the lamp tube structure. Figure 1 to Figure 2 As shown, each inclined lamp tube 100 may include a first substrate 110 for mounting on the surface of a circuit board, and the first substrate 110 has a first surface 112 and a second surface 114 facing each other, and the second surface 114 is used to be attached to the surface of the circuit board. The inclined lamp tube 100 may also include a first wafer 120 disposed on the first surface 112 of the first substrate 110, and a first lens 130 disposed on the first surface 112 of the first substrate 110 and covering the first wafer 120. Through the first substrate 110 of the inclined lamp tube 100, the inclined lamp tube 100 can be disposed on the circuit board on the peripheral side of the display screen, and the first wafer 120 on the first substrate 110 can emit light, and the light can be emitted outward through the first lens 130 (when the inclined lamp tube 100 is set as an emitting lamp tube). Moreover, the light emitted by the inclined lamp tube 100 through the first lens 130 itself has a lamp angle, so that the lamp tube structure has a corresponding lamp angle.

[0049] Furthermore, if Figure 1 to Figure 2 As shown, a first perpendicular line of the first surface 112 of the first substrate 110 of the inclined lamp tube 100 and a second perpendicular line of the second surface 114 (also referred to as a straight line perpendicular to the surface of the circuit board) form an inclined angle, and the inclined angle is an acute angle. Moreover, the first center line of the first wafer 120 is generally perpendicular to the first surface 112 of the first substrate 110, and by making the first perpendicular line of the first surface 112 of the first substrate 110 of the inclined lamp tube 100 and the second perpendicular line of the second surface 114 form an acute angle of inclined angle, so that when the second surface 114 of the first substrate 110 is installed on the surface of the circuit board, the first center line of the first wafer 120 installed on the first surface 112 of the first substrate 110 also forms an angle of inclined angle with the surface of the circuit board, and the center line of the first lens 130 coincides with the center line of the first wafer 120, that is, the first wafer 120 and the first lens 130 of the inclined lamp tube 100 are both in an inclined state relative to the surface of the circuit board.

[0050] The lamp tube structure proposed in the utility model, by arranging at least one inclined lamp tube 100 in the lamp tube unit, forms an acute angle between a first perpendicular line of a first surface 112 of a first substrate 110 of the inclined lamp tube and a second perpendicular line of a second surface 114, so that when the lamp tube unit having the inclined lamp tube 100 is installed on an infrared touch circuit board, an inclined angle is formed between the inclined lamp tube 100 and the surface of the circuit board, so that the effective angle of the inclined lamp tube 100 can be adjusted, which can be used to adjust the arrangement of the infrared touch screen optical network, so that the light distribution of the infrared touch screen is more uniform, thereby improving the performance of the touch screen component.

[0051] Furthermore, in one embodiment, if Figure 1 As shown, the first substrate 110 of the inclined lamp tube 100 can be set as a wedge-shaped plate, one inclined surface of the wedge-shaped plate is set as the second surface 114, and one non-inclined surface of the wedge-shaped plate can be set as the first surface 112. The inclined surface of the wedge-shaped plate set as the second surface 114 can be used to be mounted on the surface of the circuit board, and the first wafer 120 and the first lens 130 can be mounted on the non-inclined surface of the wedge-shaped plate set as the first surface 112. In this embodiment, by setting the first substrate 110 as a wedge-shaped plate with an inclined surface, the inclined surface of the wedge-shaped plate can be correspondingly mounted on the surface of the circuit board, so that the non-inclined surface of the wedge-shaped plate is in an inclined state, so that the first wafer 120 and the first lens 130 mounted on the non-inclined surface of the wedge-shaped plate can be in an inclined state relative to the surface of the circuit board.

[0052] For example, the wedge plate can be set as a triangular plate, the inclined surface of the triangular plate is used as the second surface 114 to be attached to the surface of the circuit board, and any right-angled surface (i.e., non-inclined surface) of the triangular plate is used as the first surface 112 to install the first wafer 120 and the first lens 130, so that the first wafer 120 and the first lens 130 are in an inclined state. In addition, the wedge plate can also be set as a trapezoidal plate, one inclined surface of the trapezoidal plate is used as the second surface 114 to be attached to the surface of the circuit board, and one non-inclined surface of the trapezoidal plate is used as the first surface 112 to install the first wafer 120 and the first lens 130, so that the first wafer 120 and the first lens 130 can also be in an inclined state.

[0053] Furthermore, in another embodiment, Figure 2As shown, the first substrate of the inclined lamp tube 100 can be set as a wedge-shaped plate, one non-inclined surface of the wedge-shaped plate can be set as the second surface 114, and one inclined surface of the wedge-shaped plate can be set as the first surface 112. The non-inclined surface of the wedge-shaped plate set as the second surface 114 can be used to be mounted on the surface of the circuit board, and the first wafer 120 and the first lens 130 can be mounted on the inclined surface of the wedge-shaped plate set as the first surface 112. In this embodiment, by setting the first substrate 110 as a wedge-shaped plate with an inclined surface, the non-inclined surface of the wedge-shaped plate can be mounted on the surface of the circuit board, and the first wafer 120 and the first lens 130 can be mounted on the inclined surface of the wedge-shaped plate. Since the inclined surface of the wedge-shaped plate is in an inclined state, the first wafer 120 and the first lens 130 mounted on the inclined surface of the wedge-shaped plate can be in an inclined state.

[0054] For example, the wedge plate can be set as a triangle plate, and the inclined surface of the triangle plate is used as the first surface 112 for mounting the first wafer 120 and the first lens 130, and any right-angled surface (i.e., non-inclined surface) of the triangle plate is used as the second surface 114 to be attached to the surface of the circuit board, so that the first wafer 120 and the first lens 130 are in an inclined state. In addition, the wedge plate can also be set as a trapezoidal plate, and one inclined surface of the trapezoidal plate is used as the first surface 112 for mounting the first wafer 120 and the first lens 130, and one non-inclined surface of the trapezoidal plate is used as the second surface 114 to be attached to the surface of the circuit board, so that the first wafer 120 and the first lens 130 can also be in an inclined state.

[0055] Furthermore, in one embodiment, if Figure 1 to Figure 2 As shown, the lamp tube unit may include a SMD lamp tube, and the SMD lamp tube is set as an inclined lamp tube 100. In this embodiment, the lamp tube structure may include only one inclined lamp tube 100. The inclination angle of the inclined lamp tube 100 may be β, and the lamp tube angle of the inclined lamp tube 100 itself may be α. The direction angle of the effective angle α of the inclined lamp tube 100 can be adjusted by the inclination angle, which is convenient for adjusting and supplementing the optical network of the infrared touch screen. In places where the infrared lamp tubes are normally arranged and the light is sparse, some infrared lamp tubes can be replaced with inclined lamp tubes 100, or inclined lamp tubes 100 can be added, so that the infrared light of the entire infrared touch screen is arranged more evenly, which can effectively improve the touch accuracy.

[0056] In addition, in one embodiment, if Figures 4 to 6As shown, the lamp tube unit may include at least two SMD lamp tubes arranged together, and at least two SMD lamp tubes work together as a transmitting lamp tube or a receiving lamp tube, that is, they are driven by the same driving signal, and transmit or receive at the same time, so that the effective working angle of an infrared transmitting lamp tube or an infrared receiving lamp tube composed of the at least two SMD lamp tubes is increased, the effective angle of the infrared lamp tube is effectively improved, and the performance and design flexibility of the infrared touch screen application are improved, wherein at least one SMD lamp tube is set as an inclined lamp tube 100. In this embodiment, at least two SMD lamp tubes can be arranged close together to form a lamp tube structure. In this lamp tube structure composed of at least two SMD lamp tubes, there is at least one inclined lamp tube 100. By making the lamp tube structure include at least two lamp tubes arranged together, and making at least one of the lamp tubes be set as an inclined lamp tube 100, not only the effective angle of the lamp tube structure can be increased, but also the light intensity of the lamp tube structure (when set as a transmitting lamp tube) can be enhanced.

[0057] Furthermore, if Figure 4 As shown, the lamp tube unit may include two SMD lamp tubes, one of which may be set as an inclined lamp tube 100, and the other of which may be set as a conventional infrared lamp tube 200. The conventional infrared lamp tube 200 is a traditional infrared lamp tube, and its lamp tube angle is its effective angle. In this embodiment, the lamp tube structure may include an inclined lamp tube 100 and a conventional infrared lamp tube 200 that are arranged close together. The inclination angle of the inclined lamp tube 100 in the lamp tube structure may be β, and the lamp tube angle of the inclined lamp tube 100 itself may be α. Moreover, the effective angle of the conventional infrared lamp tube 200 is α, so it can be known that the effective angle of the lamp tube structure composed of an inclined lamp tube 100 and a conventional infrared lamp tube 200 may be (α+β), so that the effective angle of the lamp tube structure is greater than the angle of a single lamp tube, and can also be placed in a place where the infrared touch screen has sparse light to supplement the light.

[0058] like Figure 3As shown, the conventional infrared lamp tube 200 may include a second substrate 210 for being mounted on the surface of a circuit board, and the second substrate 210 has a third surface 212 and a fourth surface 214 facing each other, and the fourth surface 214 is used to be attached to the surface of the circuit board. In addition, the conventional infrared lamp tube 200 may also include a second wafer 220 disposed on the third surface 212 of the second substrate 210, and a second lens 230 disposed on the third surface 212 of the second substrate 210 and covered outside the second wafer 220. In addition, the third perpendicular line of the third surface 212 of the second substrate 210 may be parallel to or coincide with the fourth perpendicular line (which may also refer to a straight line perpendicular to the surface of the circuit board) of the fourth surface 214. It can be seen that the third surface 212 of the second substrate 210 (i.e., the side for mounting on the second wafer 220 and the second lens 230) and the fourth surface 214 (i.e., the other side mounted on the circuit board) are in a parallel state, that is, the second substrate 210 of the conventional infrared lamp tube 200 is set as a flat plate, so that the second wafer 220 and the second lens 230 arranged on the second substrate 210 are in a state perpendicular to the fourth surface 214 of the second substrate 210, and usually the second center line of the second wafer 220 is perpendicular to the third surface 212 of the second substrate 210, so that the effective angle of the conventional infrared lamp tube is equal to its lamp tube angle α.

[0059] Moreover, when the lamp tube structure includes an inclined lamp tube 100 and a conventional infrared lamp tube 200 arranged close together, the first vertical line of the first surface 112 of the first substrate 110 of the inclined lamp tube 100 can be inclined in the direction of the third vertical line of the third surface 212 of the second substrate 210 of the conventional infrared lamp tube 200. That is, the inclined lamp tube 100 can be inclined in the direction of the conventional infrared lamp tube 200, and the two can be better gathered together, and the light intensity of the light emitted by the lamp tube structure (when set as an emitting lamp tube) can be better enhanced.

[0060] Furthermore, if Figure 4 As shown, the first substrate 110 of the inclined lamp tube 100 and the second substrate 210 of the conventional infrared lamp tube 200 can be independently arranged. In this embodiment, the inclined lamp tube 100 and the conventional infrared lamp tube 200 of the lamp tube structure are independently arranged, and the two can be independently mounted on the surface of the circuit board through the first substrate 110 of the inclined lamp tube 100 and the second substrate 210 of the conventional infrared lamp tube 200. In addition, the first wafer 120 and the first lens 130 arranged on the first substrate 110 can be arranged tilted toward the second wafer 220 and the second lens 230 arranged on the second substrate 210.

[0061] Alternatively, the first substrate 110 of the inclined lamp tube 100 and the second substrate 210 of the conventional infrared lamp tube 200 are integrated. In the present embodiment, by integrating the first substrate 110 of the inclined lamp tube 100 and the second substrate 210 of the conventional infrared lamp tube 200, the inclined lamp tube 100 and the conventional infrared lamp tube 200 of the lamp tube structure can be integrated, and both can be mounted on the surface of the circuit board at the same time. Specifically, a mounting substrate can be mounted on the surface of the circuit board, and the mounting substrate can have a wedge-shaped plate portion and a flat plate portion, wherein the wedge-shaped plate portion can be formed as the first substrate 110 of the inclined lamp tube 100, and the flat plate portion can be formed as the second substrate 210 of the conventional infrared lamp tube 200, and the first wafer 120 and the first lens 130 disposed on the wedge-shaped plate portion are tilted toward the second wafer 220 and the second lens 230 disposed on the flat plate portion.

[0062] In addition, if Figure 5 As shown, the lamp tube unit may include two SMD lamp tubes, and both SMD lamp tubes may be set as inclined lamp tubes 100. In this embodiment, the lamp tube structure may include two inclined lamp tubes 100 arranged close together. Moreover, if the inclination angle of each inclined lamp tube 100 may be β, and the lamp tube angle of each inclined lamp tube 100 itself may be α, then the effective angle of the inclined lamp tube 100 may be (α / 2+β). Therefore, the effective angle of the lamp tube structure formed by the two inclined lamp tubes 100 may be (α / 2+β+α / 2+β), that is, (α+2β), and the effective angle of the lamp tube structure may be greater than the lamp tube angle of a single inclined lamp tube 100.

[0063] Moreover, in the two inclined lamp tubes 100 of the lamp tube structure, the first perpendicular line of the first surface 112 of the first substrate 110 of one inclined lamp tube 100 is tilted toward the direction of the first perpendicular line of the first surface 112 of the first substrate 110 of the other inclined lamp tube 100. That is, the first wafer 120 (and the first lens 130) installed on the top surface of the first substrate 110 of one inclined lamp tube 100 is tilted toward the first wafer 120 (and the first lens 130) installed on the first surface 112 of the first substrate 110 of the other inclined lamp tube 100, so that the two inclined lamp tubes 100 are brought closer to enhance the light intensity of the light emitted by both (when the lamp tube structure is set as an emitting lamp tube).

[0064] Furthermore, the first vertical lines of the first surfaces 112 of the first substrates 110 of the two inclined lamp tubes 100 can be arranged relatively tilted. That is, the first wafers 120 (and the first lenses 130) arranged on the top surfaces of the first substrates 110 of the two inclined lamp tubes 100 can be arranged tilted and close to each other, which can further enhance the light intensity of the light emitted by the two. In addition, one of the inclined lamp tubes 100 can be tilted and close to the other inclined lamp tube 100, while the other inclined lamp tube 100 can be tilted in other directions.

[0065] In addition, the inclination angles of the two inclined lamp tubes 100 of the lamp tube structure may be the same or different. That is, in the two inclined lamp tubes 100 of the lamp tube structure, the inclination angles of the two inclined lamp tubes 100 may both be β, or the inclination angle of one inclined lamp tube 100 may be β1 and the inclination angle of the other inclined lamp tube 100 may be β2.

[0066] In addition, if Figure 5 In the lamp tube structure shown, the first substrates 110 of the two inclined lamp tubes 100 of the lamp tube structure can be set as one body. By setting the first substrates 110 of the two inclined lamp tubes 100 as one body, the two inclined lamp tubes 100 of the lamp tube structure can be set as one body, and the two can be mounted on the surface of the circuit board at the same time. Further, a mounting substrate can be mounted on the surface of the circuit board, and the mounting substrate can have two wedge-shaped plate parts 116, and the two wedge-shaped plate parts 116 can respectively form the first substrates 110 of the two inclined lamp tubes 100. Moreover, one wedge-shaped plate part 116 of the mounting substrate can be tilted toward the other wedge-shaped plate part 116, so that the first wafer 120 (and the first lens 130) arranged on one wedge-shaped plate part 116 is tilted and arranged close to the first wafer 120 (and the first lens 130) arranged on the other wedge-shaped plate part 116, and the first wafer 120 (and the first lens 130) arranged on the two wedge-shaped plate parts 116 can also be relatively tilted and arranged close.

[0067] In addition, the first substrates 110 of the two inclined lamp tubes 100 can also be arranged independently of each other. That is, the two inclined lamp tubes 100 of the lamp tube structure can be arranged independently of each other, and the two can be independently mounted on the surface of the circuit board through the first substrates 110 of the two inclined lamp tubes 100. Moreover, the first substrates 110 of the two inclined lamp tubes 100 can also be arranged relatively tilted, so that the first wafers 120 (and the first lenses 130) of the two inclined lamp tubes 100 are arranged tilted and close to each other.

[0068] In addition, the lamp tube structure may also include more than two SMD lamp tubes arranged closely together, and all the SMD lamp tubes may be set as inclined lamp tubes 100, or some of the SMD lamp tubes may be set as inclined lamp tubes 100 and other parts of the SMD lamp tubes may be set as conventional infrared lamp tubes 200, which may also increase the effective angle of the lamp tube structure and increase the light intensity.

[0069] In addition, the lamp tube structure can be set as an emitting lamp tube, that is, the inclined lamp tube 100 or / and the conventional infrared lamp tube 200 of the lamp tube structure can be set as an emitting lamp tube, which can be used to emit infrared light outward, and the effective angle of the lamp tube structure can be the effective angle of the infrared light emitted by it. Moreover, the emitting lamp tube provided with the inclined lamp tube 100 can increase the effective angle of infrared light emitted and the light intensity can also be increased.

[0070] In addition, the lamp tube structure can also be set as a receiving lamp tube, that is, the inclined lamp tube 100 or / and the conventional infrared lamp tube 200 of the lamp tube structure can be set as a receiving lamp tube, which can be used to receive infrared light irradiated from the outside, and the effective angle of the lamp tube structure can be the effective angle for receiving infrared light. Moreover, the receiving lamp tube provided with the inclined lamp tube 100 can increase the effective angle for receiving infrared light.

[0071] In addition, the utility model also proposes a touch screen assembly, including a display screen, and a plurality of lamp tube structures as described above, which are respectively arranged on circuit boards around the display screen. Some of the lamp tube structures are transmitting lamp tubes, and other parts of the lamp tube structures are receiving lamp tubes. By arranging at least one inclined lamp tube 100 in the lamp tube structure, since the inclined lamp tube 100 has an inclined angle, the effective angle of the lamp tube can be effectively increased, and the light output angle range of the lamp tube is greatly increased, which can improve the performance of the touch screen assembly, thereby improving the performance of product applications and the flexibility of design.

[0072] In the description of the present utility model, it should be noted that the terms "upper", "lower", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model.
