Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the embodiments of the present invention.
Fig. 4 is a schematic structural diagram of a display assembly according to the present invention, and as shown in fig. 4, a display assembly 40 of the present embodiment includes: n light emitting diodes 41.
Wherein the same pole of the n light emitting diodes 41 corresponds to n segment selection ends respectively, the other same pole of the n light emitting diodes 41 corresponds to p chip selection ends respectively, the n segment selection ends are divided into p groups, each group of segment selection ends corresponds to one chip selection end, each group of segment selection ends is used for being connected with part of m input/output I/O ports respectively, the chip selection end corresponding to each group of segment selection ends is used for being connected with any I/O port except the I/O port connected with each group of segment selection ends in the m I/O ports, the I/O port connected with the segment selection end corresponding to any two light emitting diodes 41 and the I/O port connected with the corresponding chip selection end cannot be the same at the same time, and the number m of the I/O ports is smaller thanWherein n, p and m are positive integers.
In this embodiment, the display assembly can be combined into various shapes by n light emitting diodes 41, and is applied to various devices and various occasions where information display is required. The m I/O ports to which the n leds 41 are connected may be provided by a control unit, and the specific form of the control unit is not limited in this embodiment. The control unit can be a single chip microcomputer, and also can comprise modules such as a micro control unit (Microcontroller Unit, MCU) data interface, a data latch, a key scanning and the like.
Further, the display assembly divides the n segment selection terminals respectively corresponding to the same pole of the n light emitting diodes 41 into p groups, wherein the number of the segment selection terminals in the p groups of segment selection terminals can be the same or different. And each group of segment selection terminals corresponds to one chip selection terminal, and the corresponding p chip selection terminals respectively correspond to the other same pole of the n light emitting diodes 41. That is, the n light emitting diodes 41 include n segment select terminals and p chip select terminals, one of the light emitting diodes 41 is a segment select terminal and the other is a chip select terminal, and the same pole of all the light emitting diodes 41 is a segment select terminal or an all chip select terminal. The same pole of the n light emitting diodes 41 may be a positive pole or a negative pole of the light emitting diode.
Further, each group of segment select terminals may be connected to a portion of the m input/output I/O ports, respectively, and the chip select terminal corresponding to each group of segment select terminals may be connected to any one of the m I/O ports other than the I/O port connected to each group of segment select terminals. For example, if a group of segment select terminals 1-4 are respectively connected to the corresponding I/O ports 01-04 one by one, the chip select terminal 11 of the group of segment select terminals 1-4 cannot be connected to the corresponding I/O ports 01-04.
However, the above configuration cannot ensure that there is a case where the I/O of the segment select terminal connection and the I/O of the chip select terminal connection corresponding to one light emitting diode are the same as those of the segment select terminal connection and the chip select terminal connection corresponding to any other light emitting diode, and therefore, the display module also needs to configure that the I/O port of the segment select terminal connection and the I/O port of the chip select terminal connection corresponding to any two light emitting diodes 41 cannot be the same at the same time.
Alternatively, when the segment select ends of any two light emitting diodes 41 respectively correspond to the same I/O ports, the segment select ends of any two light emitting diodes 41 respectively correspond to different I/O ports. When the segment selection ends of any two light emitting diodes 41 are respectively connected with different I/O ports, the chip selection ends of any two light emitting diodes 41 are respectively connected with the same or different I/O ports.
Further, one chip select end cannot correspond to multiple groups of segment select ends, so that the situation that the same I/O port simultaneously controls multiple light emitting diodes can be avoided, different I/O ports can control the chip select ends in n light emitting diodes 41 and a group of segment select ends corresponding to the chip select ends, and normal display requirements of a display assembly are met.
Further, based on the above, the display module can control each light emitting diode through m I/O ports to meet the actual display requirement, but cannot reduce the number of m I/O ports. Therefore, the display component can be smaller than the number m of I/O portsThe number m of the I/O ports is set, so that not only can n light-emitting diodes be guaranteed to meet actual display requirements, but also the requirement of the n light-emitting diodes on the number m of the I/O ports is reduced.
For convenience of explanation, the display assembly in this embodiment will be described in detail with a nixie tube as an example. In the prior art, the number of I/O ports needed by a nixie tube comprising n LEDs is generally equal to the number of digits of the nixie tube (generally equal to) The sum of the number of the most light emitting diodes 41 in each digital tube (8 is usually taken, i.e. the small primary light emitting diodes 41 are removed), for example, the number of I/O ports required by the conventional digital tube is usually 2+8=10. Compared with the prior art, the number m of I/O ports required by n LEDs in the display assembly is smaller than/>Port resources are saved.
Further, when the m I/O ports control n leds in the display assembly to display, the display content of the n leds may be determined first, then the I/O ports corresponding to one chip select are controlled to select the leds corresponding to a group of segment select corresponding to the chip select, and then the I/O ports respectively connected to the group of segment select corresponding to the chip select are respectively controlled to gate the corresponding leds 41, so as to complete the display process of the leds 41 in the middle of the display assembly.
Further, for the content to be displayed next by the display component, the foregoing process may be omitted herein, so that the I/O port may first select the light emitting diode 41 through the chip select, and then gate the light emitting diode 41 through a group of segment select terminals corresponding to the chip select, so as to implement the normal display process of the display component.
For example, when the display component is a two-bit nixie tube, if the display content is that the light emitting diodes in the first bit nixie tube are fully lit, four light emitting nixie tubes in the first bit nixie tube respectively correspond to the chip select end 11 and a group of segment select ends 01-04 corresponding to the chip select end 11, and the other four light emitting nixie tubes respectively correspond to the chip select end 12 and a group of segment select ends 05-08 corresponding to the chip select end 12, it may be determined that the I/O ports 01-04 corresponding to the group of segment select ends 01-04 need to output a binary "1111" first, then the I/O ports 05 corresponding to the chip select end 11 are controlled to output a binary "0", and then the I/O ports 01-04 corresponding to the group of segment select ends 01-04 are respectively controlled to output a binary "1111" so that the four light emitting nixie tubes can be conducted. Similarly, it is determined that the I/O ports 01, 02, 03, 05 corresponding to the segment selection ends 05-08 need to output a binary "1111", the I/O port 04 corresponding to the connection of the segment selection end 12 is controlled to output a binary "0", and then the I/O ports 01, 02, 03, 05 corresponding to the connection of the segment selection ends 05-08 are respectively controlled to output a binary "1111", so that the remaining four light-emitting nixie tubes can be conducted, and the process of all lighting the light-emitting diodes in the first digital tube is completed.
Further, because the lighting time of the transmitting diodes is very short, and the persistence phenomenon of vision of the person and the afterglow effect of the light emitting diode 41 are very short, although the transmitting diodes corresponding to the selecting ends of each group of segments are not actually lighted at the same time, the scanning speed is only required to be ensured to be fast enough, so that the impression of a group of stable display data is provided, the flickering sense is avoided, the dynamic display of the display component is realized, the requirement of the display component on the number of I/O ports is small, the chip cost and the packaging cost are saved, and the power consumption loss is reduced.
It will be appreciated by those skilled in the art that the nixie tube is internally composed of a-g seven bar-shaped light emitting diodes 41 and one small round point light emitting diode 41, and characters are combined according to the brightness of each light emitting diode 41. For convenience of explanation, taking the display assembly as a two-digit nixie tube, a three-digit nixie tube and a four-digit nixie tube as examples, the arrangement of the chip select end and the segment select end of each nixie tube will be described in detail through fig. 5 to 7. Wherein,

Compared with the prior two-bit nixie tube in fig. 1, the number of the I/O ports is reduced by 5 compared with 10.

Compared with the existing three-bit nixie tube in FIG. 2, the number of I/O ports is reduced by 5 compared with 11.
Fig. 7 is a schematic diagram of connection inside a four-bit nixie tube provided by the present invention, as shown in fig. 7, the four-bit nixie tube in this embodiment includes 32 leds 41, and in order to reduce the port resources to the greatest extent, the four-bit nixie tube in this embodiment needs 7I/O ports (I/O0-I/O6) for driving, wherein 6 chip select terminals COM0-COM5, 6 segment select terminals SEG0-SEG5 in five groups of segment select terminals, and 2 segment select terminals SEG0-SEG1 in one group of segment select terminals. Compared with the existing four-bit nixie tube in FIG. 3, the number of the I/O ports is reduced by 5 compared with 12.
The display assembly of this embodiment includes n light emitting diodes, where the same pole of the n light emitting diodes corresponds to n segment select ends respectively, another same pole of the n light emitting diodes corresponds to p chip select ends respectively, the n segment select ends are divided into p groups, each group of segment select ends corresponds to one chip select end, each group of segment select ends is used for being connected with a portion of m input/output I/O ports respectively, the chip select end corresponding to each group of segment select ends is used for being connected with any I/O port of the m I/O ports except the I/O port connected with each group of segment select ends, the I/O port connected with any two segment select ends corresponding to the light emitting diodes and the I/O port connected with the corresponding segment select end cannot be the same at the same time, and the number m of I/O ports is smaller thanIn this embodiment, the same I/O port is adopted to be connected with the segment selection end and the chip selection end, so that the number of I/O ports is greatly reduced, the normal display function of the display assembly is realized, the structure is simple and practical, the working performance is stable and reliable, the application range is wide, the port resources are fully utilized and saved, and the chip cost and the packaging cost are effectively reduced.
On the basis of the embodiment of fig. 4, a specific structure of the display assembly of this embodiment will be described in detail with reference to fig. 8 to 9.
Fig. 8 is a schematic structural diagram of a display assembly provided by the present invention, and fig. 9 is a schematic connecting diagram of the inside of a two-bit nixie tube provided by the present invention. As shown in fig. 8, the display assembly 40 optionally further includes: m resistors 42.
Wherein each group of segment select terminals is respectively connected with parts of m I/O ports through respective corresponding resistors 42.
Specifically, any I/O port may be connected to the corresponding segment selection terminal through a resistor 42, and any I/O port may be directly connected to the corresponding segment selection terminal, i.e., each segment selection terminal is connected to the corresponding I/O port through a resistor 42, where the resistor 42 may perform a current limiting function, so as to ensure brightness and measurement uniformity of the n leds 41. For convenience of explanation, as shown in fig. 9, the display assembly 40 is a two-bit nixie tube, wherein the display assembly 40 includes a resistor 42, each I/O port is connected to a segment selection terminal corresponding to a corresponding led through a resistor, and the connection method of the common cathode is selected as an example for each led.
Optionally, the number m of I/O ports is greater than or equal to the number of the most segment options in each set of segment options. In the prior art, taking a display component as a nixie tube as an example, the number m of I/O ports required by the nixie tube is generally equal toAnd the number of the chip selection ends is equal to the number of digits of the nixie tubes, and the number of the segment selection ends is equal to the number of the maximum light emitting diodes 41 of each digit nixie tube.
Further, since the number m of I/O ports required for the display assembly is smaller thanAnd the I/O port corresponding to any piece of selection end can select I/O ports except the I/O port connected with one group of section selection ends corresponding to the piece of selection end, namely the I/O port can be the I/O port with connection relation with each section selection end or the I/O port without connection relation with each section selection end, so that the number m of the I/O ports can be set to be larger than or equal to the number of the most sections of selection ends in each group of section selection ends.
Further, in order to further save the number of the I/O ports, optionally, the number of the middle selection ends in each group of the selection ends is m-1. Specifically, when the number of each group is m-1, since the number of the I/O ports is m, only one I/O port is available for selection at the chip select end corresponding to each group of segment select ends, and the product of the number m of the I/O ports and the number m-1 of each group of segment select ends is greater than or equal to the total number n of the light emitting diodes 41, so that the minimum number m of the I/O ports provided to the n-bit digital tube 12 is effectively ensured, and the port resources and the chip cost are greatly saved.
Further, when the number m of the I/O ports and the number m-1 of the segment selection ends of each group are determined, the number p of the chip selection ends of the n-bit digital tube 12 can be obtained by dividing the total number of the light emitting diodes 41 in the n-bit digital tube 12 by the number m-1 of the segment selection ends of each group in the p-group segment selection ends, the number p of the chip selection ends of the n-bit digital tube 12 and the number and connection mode of each chip selection end and each segment selection end in the n-bit digital tube 12 are determined, and the display function of the n-bit digital tube 12 is ensured on the premise of reducing the number of the I/O ports.
Further, taking the display component as a nixie tube as an example, since the light emitting diodes 41 in the nixie tube have two connection methods of a common cathode and a common anode, the arrangement of the middle selection end and the chip selection end of the n light emitting diodes 41 in this embodiment will be described in detail below from the two connection methods of the common cathode and the common anode.
In one aspect, alternatively, the positive electrodes of the n light emitting diodes 41 respectively correspond to the n segment select terminals, and the negative electrodes of the n light emitting diodes 41 respectively correspond to the p chip select terminals.
In this embodiment, when the n leds 41 are connected by the common cathode, the m I/O ports can input a high level to the segment selection terminal of any one of the leds 41 and a low level to the chip selection terminal of the led 41, so that the led 41 is turned on.
