Description

Technical Field

[0001] The utility model relates to the field of digital tube driving, in particular to a dual-mode digital tube driving circuit, an electronic display screen and an electronic device. Background Art

[0002] There are currently two solutions for driving digital tube displays. One is a pure hardware-driven constant current method, which requires a dedicated driver chip, or requires the controller's built-in digital tube dot matrix of 8*9=72, or traditional scanning 11*8=88 (requiring more input and output ports). The other is a pure controller software simulation, which can drive (n-1)*n lamp beads through Charlie multiplexing. However, if there are hundreds of lamp beads that need to display a tidal effect while others need to display a horse racing breathing effect, then using pure hardware will require adding a dedicated driver chip. If the controller's built-in dot matrix driver is used, it will not be able to drive hundreds of lamp beads at the same time. At the same time, the controller's built-in digital tube dot matrix module has too many lamp beads to produce a breathing effect, and the display will flicker and be unstable.

[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] Currently, there are two approaches to driving digital tube displays. One is a pure hardware-driven constant-current method, which requires a dedicated driver chip or the controller's built-in digital tube matrix (8*9=72 LEDs), or a traditional scanning method (11*8=88 LEDs) (requiring more inputs and outputs). The other is a pure controller software simulation, which can drive (n-1)*n LEDs through Charlie multiplexing. However, if hundreds of LEDs need to display a tidal effect while some need to display a horse racing breathing effect, using pure hardware requires a dedicated driver chip. Using the controller's built-in dot matrix driver cannot drive hundreds of LEDs simultaneously. Furthermore, the controller's built-in digital tube dot matrix module has too many LEDs to produce a breathing effect, resulting in flickering and instability. If using pure software, the horse racing breathing effect must be synchronized with the tidal on / off. An 8-bit controller cannot keep up, and if this is done before processing other project functions, the timeliness of processing will be affected.

[0036] In order to solve the above problems, the utility model proposes a dual-mode digital tube driving circuit.

[0037] Reference Figures 1 to 2 In one embodiment, the dual-mode digital tube driving circuit includes:

[0038] A digital tube tidal control circuit 20, wherein the output end of the digital tube tidal control circuit 20 is used to connect to the first digital tube circuit, and the digital tube tidal control circuit 20 is configured to control the first digital tube circuit to operate in a tidal mode upon receiving an enable signal;

[0039] A digital tube breathing control circuit 30, wherein the output end of the digital tube breathing control circuit 30 is used to connect to the second digital tube circuit, and the digital tube breathing control circuit 30 is configured to control the second digital tube circuit to operate in a breathing mode when receiving an enable signal;

[0040] The processor 10 has an output end connected to the input end of the digital tube tidal control circuit 20 and the input end of the digital tube breathing control circuit 30 respectively. The processor 10 is used to output an enable signal to the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 when receiving a working signal, so as to enable the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 to work.

[0041] In this embodiment, the dual-mode digital tube drive circuit can be implemented using a MUC single-chip microcontroller. The MUC single-chip microcontroller can integrate a processor 10 (Central Process Unit, CPU), memory, counters, USB, digital-to-analog converters, serial communication, and other peripheral interfaces, as well as the digital tube drive circuitry, onto a single chip, forming a chip-level computer. The digital tube tidal control circuit 20 can be the LED control module built into the single-chip microcontroller. Specifically, it is a hardware function integrated within the single-chip microcontroller that controls the connected LED lights. These modules can achieve various effects such as turning the LEDs on and off, adjusting their brightness, and flashing them through simple programming. Switching control: By setting specific register bits, simple on / off control of the LEDs can be achieved, i.e., turning them on or off. Brightness adjustment: Some LED control modules support PWM (pulse width modulation), which can be used to change the brightness of the LEDs. For example, varying brightness levels can be achieved by adjusting the duty cycle. Flashing mode: Program control or timer scheduling can be used to flash the LEDs at a specific frequency to attract attention or alert users. The tidal pattern of a digital tube is a visual effect commonly used in display devices, where lights (numbers or letters) gradually turn on and off from one side to the other, or in opposite directions. This tidal effect can make the screen appear more vivid. The digital tube breathing control circuit 30 can use the Charlie method, a circuit connection method used to drive multiple LEDs (or other light-emitting devices) and can be used to save pins. The Charlie method utilizes three electrical states: High (Hi): causes a pin to output a high voltage; Low (Lo): causes a pin to output a low voltage; and High-Z: causes a pin to drive no voltage, equivalent to being "off." Specifically, the Charlie method involves connecting two LEDs in series between any two GPIO pins, in parallel and in opposite directions. To illuminate a specific LED, the GPIO pins connected to it are set to high and low, respectively, while the remaining GPIO pins are set to high impedance. Controlling the breathing effect of an LED light can be achieved through PWM or simulated PWM to adjust the light brightness. When receiving a working signal, the processor 10 can output an enable signal to the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 to enable the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 to work. The working signal can be a user-triggered output. For example, the dual-mode digital tube drive circuit is applied to an electronic device. The electronic device has a switch button. When the user presses the button, the working signal will be output to the processor 10 in the dual-mode digital tube drive circuit.An electronic device equipped with the dual-mode digital tube driving circuit in this solution can enable the digital tube therein to have both tidal mode and breathing mode, so that a variety of dynamic effects can be displayed, and the color of the LED lamp beads in the first digital tube circuit and the second digital tube circuit can also be selected.

[0042] The technical solution of the present invention constitutes a dual-mode digital tube driving circuit through a digital tube tidal control circuit 20, a digital tube breathing control circuit 30 and a processor 10, wherein the output end of the digital tube tidal control circuit 20 is used to connect to the first digital tube circuit, and the digital tube tidal control circuit 20 is configured to control the first digital tube circuit to operate in tidal mode when receiving an enable signal; the output end of the digital tube breathing control circuit 30 is used to connect to the second digital tube circuit, and the digital tube breathing control circuit 30 is configured to control the second digital tube circuit to operate in breathing mode when receiving an enable signal; the processor 10 can output an enable signal to the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 when receiving a working signal, so as to enable the digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 to operate; this solution controls the first digital tube circuit to operate in tidal mode through the digital tube tidal control circuit 20, and controls the second digital tube circuit to operate in breathing mode through the digital tube breathing control circuit 30, so that the dual-mode digital tube driving circuit can have tidal mode and breathing mode at the same time, thereby displaying a variety of dynamic effects.

[0043] Reference Figure 3 In one embodiment, the dual-mode digital tube driving circuit further includes:

[0044] A driving interface is connected to the output end of the digital tube tidal control circuit 20 and the output end of the digital tube breathing control circuit 30, and the driving interface is used to connect the first digital tube circuit and the second digital tube circuit.

[0045] In this embodiment, the drive interface can be multiple USB or serial communication interfaces, or an interface driver with multiple interfaces that can connect to multiple LED lights. The multiple LED lights can constitute a first digital tube circuit and a second digital tube circuit. The digital tube tidal control circuit 20 and the digital tube breathing control circuit 30 can be connected to the first digital tube circuit and the second digital tube circuit respectively through the drive interface, thereby controlling the first digital tube circuit to operate in tidal mode and controlling the second digital tube circuit to operate in breathing mode. Figure 3 Among them, LED0 to LED8 can be connected to the first digital tube, and LED_A to LED_E can be connected to the second digital tube.

[0046] In one embodiment, the digital tube tidal control circuit 20 is configured in a dot matrix scanning mode, and the processor 10 is used to output an enable signal to the digital tube tidal control circuit 20 when receiving a working signal, so that the digital tube tidal control circuit 20 drives the first digital tube circuit to operate in the dot matrix scanning mode.

[0047] In this embodiment, the digital tube tidal control circuit 20 is configured to be in a dot matrix scanning mode. For example, the digital tube tidal control circuit 20 drives the first digital tube circuit composed of 8*9 digital tubes. The digital tube tidal control circuit 20 is connected to the first digital tube circuit through 9 pins to perform driving control. For details, please refer to Figure 4 Drive control using a dot matrix scanning mode saves space and allows for the display of more information within a relatively small area. Different lighting combinations can also generate a variety of characters, graphics, and animations to meet diverse application requirements. Multiple dot matrices can be cascaded to create a larger display area, adapting to varying display needs. The number of digital tubes controlled by the dot matrix drive can be adjusted based on actual conditions and user needs.

[0048] In one embodiment, the dual-mode digital tube driving circuit further includes:

[0049] The timer is connected to the processor 10, and the processor 10 is used to trigger the timer to start timing when outputting an enable signal to the digital tube breathing control circuit 30, and to interrupt once when receiving the timing trigger signal of the timer, and then output an enable signal to the digital tube breathing control circuit 30.

[0050] In this embodiment, the timer can be set to a fixed time interval, such as 50us, to enter an interrupt, refresh the LED lamp bead once, and then output an enable signal to the digital tube breathing control circuit 30 to adjust the LED brightness. Interrupt settings can provide more precise timing control than polling, because the interrupt mechanism allows the hardware to accurately trigger the handler at a predetermined time point. In addition, interrupt processing can reduce CPU waiting time, reduce CPU burden, and avoid the waste of resources caused by busy waiting. Resetting the timer after each interrupt processing ensures that the execution of each task is not missed, even if a task execution time exceeds expectations.

[0051] In one embodiment, the timer includes:

[0052] An automatic reload register is used to stepwise increase the timing time of the timer when the timer outputs a timing trigger signal.

[0053] In this embodiment, the value of the automatic reload register determines the upper limit of the timer's count. When the timer counter reaches the value of the automatic reload register, the counter automatically resets to 0 and generates a timer overflow (or update) interrupt. And when the counter is reset, the value of the automatic reload register is reloaded into the counter, thereby achieving continuous timing operation. This automatic reload mechanism allows the timer to repeatedly generate interrupts or events within a specified time interval. In addition, the value of the automatic reload register can be dynamically modified at runtime according to actual application requirements, thereby flexibly adjusting the timer period. In this embodiment, by changing the timer's time base through the automatic reload register, the time when the timer enters the interrupt can be flexibly adjusted.

[0054] The utility model also provides an electronic display screen.

[0055] Reference Figure 5 In one embodiment, the electronic display screen includes a display screen body, a digital tube circuit and the dual-mode digital tube driving circuit as described above. The digital tube circuit is arranged on the display screen body, and the controlled end of the digital tube circuit is connected to the output end of the digital tube tidal control circuit 20 and the output end of the digital tube breathing control circuit 30 in the dual-mode digital tube driving circuit.

For example, by providing the aforementioned electronic display screen on an electronic cigarette, the digital tube can display tidal and breathing patterns, adding aesthetics and personalization to the electronic cigarette. It is understood that since the aforementioned electronic display screen is used in the electronic device of the present invention, the embodiments of the electronic device of the present invention include all technical solutions of all the aforementioned electronic display screen embodiments, and the technical effects achieved are identical, and therefore will not be further elaborated here.
