[0025] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0027] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] See also Figure 1-Figure 2 An embodiment of a touch display panel with lamp beads provided in an embodiment of the present invention includes:

[0029] A touch display panel with lamp beads includes a circuit board 4 and a touch display unit 3 arranged on the circuit board 4. The touch display unit 3 includes a lamp bead 1 and a touch button 2. The touch button 2 is arranged outside the lamp bead 1. The touch button 2 is a light-transmitting button and is used to control and display the state changes of the lamp bead 1.

[0030] The circuit board 4 includes an upper circuit board 41 and a lower circuit board 42. The upper circuit board 41 is located above the lower circuit board 42. The touch button 2 is set on the upper circuit board 41, and the lamp bead 1 is set on the lower circuit board 42. The upper circuit board 41 is electrically connected to the lower circuit board 42.

[0031] It is understandable that, in a specific implementation, by providing a translucent touch button 2 on the upper circuit board 41 and providing the lamp bead 1 on the lower circuit board 42, the touch button 2 is distributed above the lamp bead 1. This vertical structure design makes the touch button 2 and the lamp bead 1 integrated. The touch button 2 is used to control and display the state changes of the lamp bead 1. The current fire power level is directly displayed on the touch button 2 through the state of the lamp bead 1 under the button. The operation is simple and clear, which solves the problem of adding additional silk screen instructions to the touch button 2 when the traditional touch button 2 is separated from the lamp bead 1. At the same time, the light of the lamp bead 1 is displayed inside the touch button 2, and the touch button 2 does not need to occupy additional space, which effectively reduces the space occupied by the circuit board 4, is beneficial to the layout of the circuit board 4, and improves the aesthetics of the product and the user interaction experience.

[0032] In a more specific embodiment, a touch display unit 3 contains multiple lamp beads 1. When a working lamp bead 1 is burned out, another lamp bead 1 in the touch display unit 3 can be quickly replaced, effectively extending the service life of the touch display unit 3.

[0033] In a more specific embodiment, the lamp bead 1 is multi-colored, with each color corresponding to a power level. In the specific configuration, considering the product size and the limited size of the circuit board 4, only one touch display unit 3 can be provided in this embodiment. The touch display unit 3 includes a multi-colored lamp bead 1 and a touch button 2. It is understandable that in this embodiment, only one touch button 2 is provided, and each touch button 2 is provided with one lamp bead 1. In specific implementation, the current power level is directly displayed through the multiple color states of the lamp bead 1, making operation simple and clear.

[0034] In a more specific embodiment, a plurality of touch-display units 3 are sequentially distributed on a circuit board 4, and the touch-display units 3 are not connected to each other. The display effect is presented by the number of illuminated lamp beads 1, or the number of lamp beads 1 color changes indicates the location of the touched touch button 2. In other more specific embodiments, the plurality of touch-display units 3 can be distributed in strips or bands, such as arcs, straight lines, and waves, depending on the product design requirements.

[0035] It should be noted that, under normal circumstances, a finger does not directly touch the touch button 2. Instead, a touch panel 5 is provided on the touch button 2. The finger touches the panel area corresponding to the touch button 2, creating a capacitive effect between the finger and the touch button 2 through the panel. The touch sensor chip 6 collects the key input signal, identifies changes in the signal, and performs corresponding functional processing. In some more specific embodiments, the lamp beads 1 are monochrome. It will be appreciated that, in specific implementations, the display effect is determined by the number of lamp beads 1 that are illuminated. The PCB board is provided with M touch display units 3, with the 1st on the leftmost and the Mth on the rightmost. If a finger touches the panel area corresponding to the touch button 2 of the Nth (N≤M)th) touch display unit 3, the 1st to Nth lamp beads are illuminated, while the N+1th to Mth lamp beads are deactivated. When N=M, all lamp beads are illuminated. Alternatively, the 1st to N-1th lamp beads are illuminated, while the Nth to Mth lamp beads are deactivated. Since it is the first lamp bead 1 to light up under the finger, rather than just the lamp bead 1 under the finger, there is no problem of the finger covering a single touch display unit 3 to block the light source of the lamp bead 1, causing the user to be unable to quickly identify whether the touch is in place. It can be understood that this embodiment provides multiple touch buttons 2 and multiple lamp beads 1 corresponding to the touch buttons 2. In specific implementation, the current power level is directly displayed by the number of lit lamp beads 1, which makes the operation simple and clear.

[0036] In other more specific embodiments, the lamp beads 1 are multi-colored. It is understandable that, in specific implementations, the display effect is presented by changing the color of the lamp beads 1. M touch display units 3 are distributed on the circuit board 4 in sequence, with the 1st on the far left and the Mth on the far right. If a finger touches the panel area corresponding to the touch button 2 of the Nth (N≤M)th touch display unit 3, then the 1st to Nth lamp beads change to bright color B, and the N+1th to Mth lamp beads still maintain color A. When N=M, all lamp beads change to bright color B; or the 1st to N-1th lamp beads change to bright color B, and the Nth to Mth lamp beads 1 still maintain color A. Since it is the lamp beads 1 from the 1st to the lamp beads 1 under the finger that change color, rather than simply changing the color of the lamp beads 1 under the finger, there will be no problem of the finger covering a single touch display unit 3 to block the light source of the lamp bead 1, causing the user to be unable to quickly identify whether the touch is in place. It can be understood that this embodiment is provided with a plurality of touch buttons 2 and a plurality of lamp beads corresponding to the touch buttons 2. In specific implementation, the current fire power level is directly displayed by the number of color changes of the lamp beads 1, and the operation is simple and clear.

[0037] It is understandable that the touch button 2 can be light-transmissive on any surface. In some specific implementation schemes, the touch button 2 is raised on the surface of the product, and can be light-transmissive on the top surface and / or side surface of the touch button 2 according to design requirements. In other specific implementation schemes, the touch display unit 3 is arranged at the edge of the product, and the edge is a curved surface or a folded surface. The irradiation direction of the lamp bead 1 may be inconsistent with the touch direction of the touch button 2. The irradiation direction of the lamp bead 1 is on one side of the product, and the touch direction of the touch button 2 is on the adjacent surface of the product. In this case, the light-transmissive surface of the touch button 2 may be the side surface. In some specific implementation schemes, according to the product layout, the touch display unit 3 is arranged in the middle of the surface of the product, the irradiation direction of the lamp bead 1 is consistent with the touch direction of the touch button 2, and the lamp bead 1 is displayed on the surface of the touch button 2. In this case, the light-transmissive direction of the touch button 2 is the top surface.

[0038] In a more specific embodiment, the touch button 2 is made of a conductive material. During implementation, a capacitive effect is generated when a finger touches the touch button 2. The touch sensing chip collects the key input signal, identifies the signal change, and performs corresponding functional processing.

[0039] In a more specific embodiment, the touch key 2 includes a copper key 22, which is embedded in the circuit board 4. Copper is used as the key material because copper has good electrical conductivity and stability.

[0040] In a more specific embodiment, the copper key surface is coated with protective paint.

[0041] In a more specific embodiment, the copper buttons 22 are copper blocks, and multiple copper buttons 22 are distributed on the circuit board 4 in a strip or strip shape. Gaps are provided between adjacent copper buttons 22 to prevent them from interfering with each other. These multiple copper buttons are arranged in strips or strips at regular intervals and in a sequence, forming a continuous "slider" area on the upper circuit board 41. This design allows users to intuitively change the touch position of the buttons through finger sliding operations, thereby achieving control of the LEDs.

[0042] In a more specific embodiment, multiple lamp beads 1 are also arranged in an orderly and spaced manner into strips or belts to form a "lamp bead bar" corresponding to the "slider" and distributed on the lower circuit board 42, providing a structural basis for achieving touch and display synchronization. Wherever the finger touches, the display of the lamp bead changes.

[0043] In a more specific embodiment, an opening 21 is provided in the middle of the copper button 22, and the lamp bead 1 is disposed directly below the opening 21, thereby vertically integrating the lamp bead 1 with the touch button 2. It is understood that, in a specific implementation, the opening 21 is used to transmit light and constrain the illumination shape of the lamp bead 1. The opening 21 can be configured in any shape, including circular, square, etc., according to actual needs, to achieve the desired shape display effect and enhance the aesthetics of the display of the lamp bead 1.

[0044] In some more specific embodiments, openings 21 are also provided on both sides of the copper button 22, that is, openings 21 are provided in the middle of the copper button 22 and in the gap between two adjacent copper buttons 22, and lamp beads 1 are provided below the openings 21. When a finger touches the upper part of the gap between two adjacent copper buttons 22, that is, the two copper buttons 22 are touched at the same time, the touch sensing chip 6 can identify the position of the finger and control the lamp beads below the gap to change the display, which is equivalent to increasing the number of buttons without increasing the ports of the touch sensing chip 6, saving chip resources. At the same time, the total number of lamp beads has increased, and the lamp beads will not be too far apart, which is more beautiful, and the corresponding number of gears has also increased. Assuming there are N copper buttons 22, there are N-1 gaps between adjacent copper buttons 22, so the total number of equivalent buttons is 2N-1, and the total number of lamp beads is also 2N-1. In a more specific embodiment, the edges of two adjacent copper keys 22 are staggered. In some more specific implementations, the edges of two adjacent copper keys 22 are staggered to form a broken line gap or a curved gap. The purpose of the staggered edges of two adjacent copper keys 22 is to make the staggered area of the two adjacent keys larger and more balanced. When the finger touches above this staggered area, it can better touch the two copper keys 22 at the same time.

[0045] In a more specific embodiment, the upper circuit board 41 is connected to the lower circuit board 42 through a support member 43. The upper circuit board 41 is positioned and supported by the support member 43, and the relative position and height of the upper circuit board 41 and the lower circuit board 42 can be fixed to meet the requirements of assembly, display and touch.

[0046] In a more specific embodiment, the support member 43 is an elastic support member. The elastic effect of the support member 43 is to ensure that the touch button 2 and the touch panel 5 maintain close contact, and prevent poor contact caused by factors such as gravity or transportation vibration. In some more specific embodiments, the support member 43 is a non-elastic member, and an elastic component is added below the lower circuit board 42. The elastic component is used to elastically support the lower circuit board 42 and the upper circuit board 41 as a whole, so that the touch button 2 and the touch panel 5 maintain close contact, and prevent poor contact caused by factors such as gravity or transportation vibration.

[0047] See also Figure 3In a more specific embodiment, the touch display panel further includes a touch sensing chip 6 and a display driver chip 7. Both the touch sensing chip 6 and the display driver chip 7 are disposed on a circuit board 4. The touch buttons 2 are connected to the input of the touch sensing chip 6, the output of the touch sensing chip 6 is connected to the input of the display driver chip 7, and the output of the display driver chip 7 is connected to the lamp beads 1. The touch sensing chip 6 is an MCU (Microcontroller Unit) with touch recognition and processing functions.

[0048] In a more specific embodiment, the touch sensing chip 6 and the display driver chip 7 can be arranged on the upper circuit board 41 or the lower circuit board 42 according to actual needs. In a more specific embodiment, the touch sensing chip 6 is arranged on the upper circuit board 41, and the display driver chip 7 is arranged on the lower circuit board 42.

[0049] In a more specific embodiment, the touch sensing chip 6 is provided with multiple input terminals, and the input terminal of each touch sensing chip 6 is only connected to one touch button 2. The display driver chip 7 is provided with multiple output terminals, and the output terminal of each display driver chip 7 is only connected to one lamp bead 1 or the lamp beads of multiple touch display units 3 are connected to the output terminal of the display driver chip 7 in a dot matrix manner.

[0050] Typically, the lamp beads of multiple touch display units 3 are connected to the output terminals of the display driver chip 7 using a dot matrix, such as the common 7×10 dot matrix. In this dot matrix, although each lamp requires two ports to control, a dot matrix consisting of only 17 (7+10) ports can control up to 70 lamps. This design effectively saves ports on the display driver chip 7. Moreover, the saved extra ports can be used for other displays, such as digital tubes and flat tubes.

[0051] It can be understood that in a specific implementation, multiple touch display units 3 are arranged on the circuit board 4 in sequence, and gaps are set between the touch display units 3 and they are not connected to each other to prevent the keys from being short-circuited and causing touch failure. In a more specific embodiment, the bottoms of the lamp beads 1 and the touch keys 2 are both connected to the circuit board 4, and gaps are set between the lamp beads 1 and the touch keys 2 and they are not connected to each other to ensure that the placement of the lamp beads 1 will not interfere with the accuracy of touch sensing.

[0052] A touch display component includes a touch display board with lamp beads and a touch panel 5, the bottom of the touch panel 5 is connected to the touch button 2, and the touch panel 5 is made of a material with a smooth upper surface and transparent and translucent. In some more specific embodiments, the touch panel 5 is made of glass, including microcrystalline glass or high borosilicate glass, etc. In a specific implementation, when the human body or other conductive objects approach or contact the touch area of the touch button 2 on the glass surface, a capacitive effect is generated. The touch sensing chip 6 can identify the change in the signal by collecting the input signal of the touch button 2 and then perform the corresponding function. It can be understood that the material selection of the touch panel 5 in this embodiment ensures the transmittance, durability and aesthetics of the touch panel 5. In a specific implementation, when the finger slides back and forth above the strip area composed of multiple touch display units 3 on the touch panel 5, due to the high processing speed of the MCU, the display and touch follow each other in almost real time, thereby achieving dynamic following in the case of dynamic touch.

[0053] In a more specific embodiment, the circuit board 4 is a PCB board.

[0054] In summary, in this embodiment, multiple copper buttons 22 are arranged in an orderly and spaced manner into strips or belts to form "sliders" distributed on the upper circuit board 41, and multiple lamp beads 1 are also arranged in an orderly and spaced manner into strips or belts to form "lamp bead strips" corresponding to the "sliders" and distributed on the lower circuit board 42, so as to achieve touch and display synchronization. Wherever the finger touches, the display of the lamp bead 1 changes to that place, realizing dynamic following. The level of the associated gear can be determined according to the number of lamp beads 1 that are lit, or the color change of the lamp 1, and the glass touch panel 5 is combined to make the product more technological.

[0055] It should be noted that, in the present invention, the touch sensing chip 6 and the display driver chip 7 provide the hardware basis for the touch button 2 to control the state changes of the lamp beads. The content involving specific programming to further realize the intelligent function is the method content that can be implemented by technical personnel based on common knowledge. These method contents are not within the scope of this solution. The above description is only combined with common knowledge to illustrate the beneficial effects that can be achieved by the improvement of this hardware structure.
