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.

[0028] 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.

[0029] See also Figures 1-4 An embodiment of a touch display panel with lamp beads provided in an embodiment of the present invention includes:

[0030] A touch display panel with lamp beads includes a circuit board 6 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.

[0031] It is understandable that, in specific implementation, the translucent touch button 2 is set on the outside of the lamp bead 1. The touch button 2 is used to control and display the state changes of the lamp bead 1, realizing the integrated design of the lamp bead 1 and the touch button 2. 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, solving 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 lamp bead 1 is nested inside the touch button 2. At the same time, the integrated design of the touch button 2 nested outside the lamp bead 1 means that the touch button 2 does not need to occupy additional space, effectively reducing the space occupied by the circuit board 4, facilitating the layout of the circuit board 4, and improving the aesthetics of the product and the user interaction experience.

[0032] 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.

[0033] 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.

[0034] In a more specific embodiment, the lamp bead 1 is multi-colored, with each color corresponding to a power level. During 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 is provided with one lamp bead 1. During specific implementation, the current power level is directly displayed through the multiple color states of the lamp bead 1, making operation simple and clear.

[0035] 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.

[0036] It should be noted that, under normal circumstances, a finger does not directly touch the touch button 2. The touch button 2 is provided with a touch panel. The finger touches the panel area corresponding to the touch button 2, and a capacitive effect is generated between the finger and the touch button 2 through the panel. The touch sensing chip 6 collects the key input signal, identifies the signal changes, and performs corresponding functional processing.

[0037] In some more specific embodiments, the lamp beads 1 are monochrome. It is understandable that, in a specific implementation, the display effect is presented by the number of lamp beads 1 that are lit. There are M touch display units 3 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 are lit, and the N+1th to Mth lamp beads are extinguished. When N=M, all lamp beads are lit; or the 1st to N-1th lamp beads are lit, and the Nth to Mth lamp beads are extinguished. Since it is the lamp beads 1 from the 1st to the lamp beads 1 under the finger that are lit, rather than simply lighting 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 lit lamp beads 1, and the operation is simple and clear.

[0038] 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.

[0039] In a more specific embodiment, touch button 2 is constructed of a resilient conductive material. During implementation, a finger touching the panel area corresponding to touch button 2 generates a capacitive effect. The touch sensor chip collects the key input signal, identifies the signal changes, and performs corresponding functional processing. The elasticity of touch button 2 ensures close contact between touch button 2 and the touch panel, preventing contact loss caused by factors such as gravity or transportation vibration.

[0040] In a more specific embodiment, the touch button 2 includes a touch spring 23, and the lamp bead 1 is disposed within the coil of the touch spring 23. The coils of the touch spring 23 are densely packed, focusing most of the light from the lamp bead 1 at the spring opening. In some more specific embodiments, the touch spring 23 is made of stainless steel wire.

[0041] In a more specific embodiment, the touch button 2 further includes a touch sheet 22 having an opening 21 in the middle thereof. The bottom of the touch sheet 22 is connected to the spring opening of a touch spring 23. The opening 21 is used to constrain the illumination shape of the lamp bead 1. The opening 21 of the touch sheet 22 can be configured in any shape as needed, including circular, square, etc., to achieve the desired display effect and enhance the aesthetics of the display of the lamp bead 1.

[0042] In a more specific embodiment, the touch sheet 22 is made of a conductive material. In some more specific implementations, the touch sheet 22 is made of a conductive material that is easy to open holes, such as a stainless steel sheet.

[0043] See also Figure 5In 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.

[0044] 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 connected to a 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.

[0045] 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.

[0046] It is understandable that, in a specific implementation, a plurality of touch display units 3 are sequentially arranged on the circuit board 4 , with gaps provided between the touch display units 3 and without being connected to each other, to prevent key short circuits and touch failure.

[0047] In a more specific embodiment, the bottoms of the lamp bead 1 and the touch button 2 are both connected to the circuit board 4, and a gap is set between the lamp bead 1 and the touch button 2 and they are not connected to each other, ensuring that the placement of the lamp bead 1 will not interfere with the accuracy of touch sensing.

[0048] In a more specific embodiment, the circuit board 4 is a PCB board.

[0049] 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 and light-transmitting upper surface. 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 of the signal by collecting the input signal of the touch button 2 and then perform corresponding functional processing. 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.

[0050] In summary, this embodiment realizes the synchronization of touch and display. 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 adjusted according to the number of lamp beads 1 that are lit, or the color change of the lamp 1. In combination with the touch panel 5 made of glass, the product has a more technological feel.

[0051] 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. The effect realization in the embodiment of the new invention does not depend on the realization of these method contents used for examples.

[0052] It should be noted that the terms used to describe the positional relationships in the above examples and drawings are only for illustrative purposes and should not be construed as limiting this patent; the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
