The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.

The embodiment of the utility model provides an LED display module. Referring to fig. 2, the led display module 100 includes an input interface module 11, a driving circuit 12, and a display module 13.

The input interface module 11 can be plugged with an external interface, and when the input interface module 11 is plugged with the external interface, the input interface module 11 can receive and transmit control signals input by the external interface.

The driving circuit 12 is electrically connected with the input interface module 11, and can generate a driving signal according to the control signal transmitted by the input interface module 11.

The display module 13 is electrically connected to the driving circuit 12, and is capable of displaying a picture under the driving of the driving signal.

Referring to fig. 3, the input interface module 11 includes a first row of pin groups 111 and a second row of pin groups 112, the first row of pin groups 111 includes a plurality of first pin units 1111 for implementing corresponding pin functions, and in the first row of pin groups 111, first pin units 1111 for implementing different or same pin functions may be included, for example, in fig. 3, the first pin unit 1111_1 and the first pin unit 1111_2 implement different pin functions, and the first pin unit 1111_2 and the first pin unit 1111_3 implement the same pin functions.

The second row pin group 112 includes a plurality of second pin units 1121 implementing corresponding pin functions, and in the second row pin group 112, second pin units 1121 implementing different or same pin functions may be included, for example, in fig. 3, the second pin units 1121_1 implement different pin functions from the first pin units 1121_2, and the second pin units 1121_2 implement the same pin functions as the second pin units 1121_3.

When the first row of pin groups 121 rotates around the center point 11A of the input interface module 11 by a designated angle, the first pin units 1111 and the second pin units 1121, which implement the same pin functions, overlap. For example, referring to fig. 4, before the first row of pin sets 121 rotates around the center point 11A of the input interface module 11, the first pin units 1111 in the first row of pin sets 121 are sequentially the first pin unit 1111_1, the first pin unit 1111_2, the first pin unit 1111_3 … …, the first pin unit 1111_n-2, and the first pin unit 1111_n from top to bottom, and after the first row of pin sets 121 rotates around the center point 11A of the input interface module 11 by a predetermined angle, the first pin units 1111 in the first row of pin sets 121 are sequentially the first pin unit 1111_n, the first pin unit 1111_n-1, the first pin unit 1111_n-2, the first pin unit 1111_3 … …, the first pin unit 1111_2, and the first pin unit 1111_1 from top to bottom.

Referring to fig. 3, after the first row of pin groups 121 rotates around the center point 11A of the input interface module 11 by a designated angle, the first pin unit 1111_n and the second pin unit 1121_1 which implement the same pin function overlap, the first pin unit 1111_n-1 and the second pin unit 1121_2 which implement the same pin function overlap, and the first pin unit 1111_3 and the second pin unit 1121_n-2 which implement the same pin function overlap … …, the first pin unit 1111_2 and the second pin unit 1121_n-2 which implement the same pin function overlap, and the first pin unit 1111_1 and the second pin unit 1121_n_2 which implement the same pin function overlap.

Similarly, when the second pin group 112 rotates around the center point 11A of the input interface module 11 by a specified angle, the second pin unit 1121 implementing the same pin function coincides with the first pin unit 1111.

Therefore, no matter whether the input interface module 11 is plugged in the front or the back with the external interface, the control signals transmitted to the driving circuit 12 by the input interface module 11 are the same, so that the input interface module supports the front and the back plugging with the external interface, so that each LED display module 100 can receive the required signals for display by itself only through the input interface module 11, and two interconnected input interfaces are not required to be arranged, thereby reducing the design difficulty, workload, power supply ripple and cost and improving the signal transmission stability.

In some embodiments, the specified angle is 180 degrees. It should be further understood that the designated angle may be any other suitable angle, and the rotation direction may be either clockwise or counterclockwise, which is not limited herein, so long as the first pin unit 1111 and the second pin unit 1121, which perform the same pin function, overlap after the first pin group 111 rotates around the center point 11A of the input interface module 11 by the designated angle.

In some embodiments, referring to fig. 5, the first row of pin sets 111 includes N first pin units 1111, the N first pin units are arranged according to the sequence numbers 1 to N, the second row of pin sets 112 includes N second pin units 1121, the N second pin units 112 are arranged according to the sequence numbers n+1 to 2N, and the first pin units 1111 and the second pin units 1121 with the sequence numbers 2n+1 perform the same pin functions.

For example, the serial numbers of the first and second pin units 1111 (1) and 1121 (2N) and 1+2n=2n+1, and the first and second pin units 1111 (1) and 1121 (2N) implement the same pin function. For another example, the serial numbers of the first pin unit 1111 (N-2) and the second pin unit 1121 (N+3) and N-2+N+3=2N+1, and the first pin unit 1111 (N-2) and the second pin unit 1121 (N+3) implement the same pin function.

By arranging a plurality of power supply pin units on the input interface module 11, the power supply current input to the LED display module 100 is improved, and the power supply requirement of the LED display module 100 is met.

In some embodiments, referring to fig. 8, in the input interface module 11 provided in the embodiment of the present utility model, the pin functions implemented by the first pin unit 1111 are different except for the power supply pin unit for the first pin group 111, and correspondingly, the pin functions implemented by the second pin unit 1121 are different except for the power supply pin unit for the second pin group 112.

It is to be understood that the first pin units 1111 of the first pin set 111 and the second pin units 1121 of the second pin set 112 may be arranged in other arrangements different from those shown in fig. 8, which are not described herein, so long as the input interface module 11 can support the forward and backward plugging with the external interface.

In some embodiments, referring to fig. 9, in the input interface module 11 provided in the embodiment of the present utility model, for the first pin group 111, a first pin unit 1111 that performs the same pin function may be included in addition to the power supply pin unit, and for the second pin group 112, a second pin unit 1121 that performs the same pin function may be included in addition to the power supply pin unit.

It is to be understood that the first pin units 1111 of the first pin set 111 and the second pin units 1121 of the second pin set 112 may be arranged in other arrangements different from those shown in fig. 9, which are not described herein, so long as the input interface module 11 can support the forward and backward plugging with the external interface.

Referring to fig. 12, in general, each of the light beads on the display surface of the conventional LED display module is arranged in the same direction, each of the light beads includes sequentially arranged light emitting diodes a, B and C, and the colors of the light emitting diodes a, B and C are different. However, when the user looks at the edge of the display surface longitudinally, the same light emitting diode is used as the edge, and the light emitting diode is closer to the user, so that the area of the light emitting diode, which is shielded by the shell structure of the lamp bead, is larger than that of other light emitting diodes, and therefore, the problem of color cast exists when the user looks at the edge of the display surface longitudinally.

It can be understood that, since each LED display module 100 has only one input interface module 11, in the case that the input interface module 11 of the LED display module 100 supports forward and backward plugging with an external interface, referring to fig. 13, the installation direction of the left LED display module 100 is opposite to that of the right LED display module 100, for example, when the installation direction of the left LED display module 100 is downward, the installation direction of the right LED display module 100 is upward, and if the plurality of light beads 131 arranged in matrix on the display module 13 of each LED display module 100 adopt the arrangement manner shown in fig. 10, color difference between the display screen of the left LED display module 100 and the display screen of the right LED display module 100 will occur when the display screen of the left LED display module 100 is controlled to display.

In some embodiments, for each display module 13, in two adjacent beads 131 in the same row/column, the front bead 131 rotates by a preset angle according to a preset rotation direction with the center of the bead as a rotation axis, and then translates by a preset distance to overlap with the rear bead 131.

The preset rotation direction may be clockwise or counterclockwise.

The preset angle may be any suitable angle, such as 60 degrees, 90 degrees, 180 degrees, and so on.

In some embodiments, the preset angle is 90 degrees.

In this embodiment, for two adjacent beads 131 in the same row, for example, please refer to fig. 14a and 14b together, the former bead 131 rotates 90 ° in the counterclockwise direction with the center of the bead as the rotation axis, and then translates by a predetermined distance to overlap with the latter bead 131.

It should be noted that, in the related drawings, the first light emitting diode of each light bulb 131 is denoted by the letter "R", the second light emitting diode of each light bulb 131 is denoted by the letter "G", and the third light emitting diode of each light bulb 131 is denoted by the letter "B".

For another example, referring to fig. 14c and 14d, the front bead 131 rotates 90 degrees clockwise around the center of the bead, translates a predetermined distance, and then overlaps with the rear bead 131.

For two adjacent beads 131 in the same row, for example, please refer to fig. 14a and 14c together, the former bead 131 rotates 90 degrees in the counterclockwise direction with the center of the bead as the rotation axis, and then translates for a predetermined distance to overlap with the latter bead 131.

For another example, referring to fig. 14b and 14d, the front bead 131 rotates 90 degrees clockwise around the center of the bead, translates a predetermined distance, and then overlaps with the rear bead 131.

In some embodiments, the preset angle is 180 degrees.

In this embodiment, referring to fig. 15, for two adjacent beads 131 in the same row, the front bead 131 rotates 180 degrees in a clockwise direction or a counterclockwise direction with the center of the bead as the rotation axis, and then translates for a predetermined distance to overlap with the rear bead 131.

For two adjacent beads 131 in the same row, as shown in fig. 15, the front bead 131 rotates 180 degrees in a clockwise direction or a counterclockwise direction with the center of the bead as a rotation axis, and then translates for a predetermined distance to overlap with the rear bead 131.

Therefore, in this embodiment, by setting two adjacent beads in the same row or the same column, the former bead rotates by a preset angle according to a preset rotation direction with the center of the bead, and then translates for a preset distance to overlap with the latter bead, so as to adjust the placement direction of each bead, and ensure that each edge position of the display module is not the same light emitting diode, thereby ensuring that color cast problem does not exist when a user looks at each edge position of the display module from different directions.

The preset distance can be freely set according to actual requirements, and is not limited herein. It can be understood that the size of the preset distance affects the resolution of the display module 13, when the preset distance is larger, fewer pixels are accommodated under a certain area, the resolution is lower, and when the preset distance is smaller, more pixels are accommodated under a certain area, the resolution is higher.

In some embodiments, in two adjacent rows of beads 131, the preset rotation direction of the first row of beads 131 is opposite to the preset rotation direction of the second row of beads 131. The first row of beads 131 and the second row of beads 131 are two adjacent rows of beads 131.

The preset rotation direction of the first row of beads 131 means that, of two adjacent beads 131 of the first row of beads 131, the former bead 131 rotates by a preset angle according to the preset rotation direction with the center of the bead as a rotation axis, and then translates by a preset distance to coincide with the latter bead 131. The preset rotation direction of the second row of beads 131 is the same, and will not be described here again.

Here, the first row of beads 131 and the second row of beads 131 are used to represent any two adjacent rows of beads 131 in the display module 13, that is, in the display module 13, it is satisfied that the preset rotation direction of one row of beads 131 in any two adjacent rows of beads 131 is opposite to the preset rotation direction of the other row of beads 131.

For example, the display module 13 includes four rows of beads 131, the first row of beads 131 and the second row of beads 131 are two adjacent rows of beads 131, the preset rotation direction of the first row of beads 131 is opposite to the preset rotation direction of the second row of beads 131, the preset rotation direction of the second row of beads 131 and the preset rotation direction of the third row of beads 131 are opposite to the preset rotation direction of the third row of beads 131, the preset rotation direction of the third row of beads 131 and the preset rotation direction of the fourth row of beads 131 are opposite to the preset rotation direction of the third row of beads 131.

When the preset rotation direction of the first row of beads 131 is clockwise, the preset rotation direction of the second row of beads 131 is counterclockwise, and when the preset rotation direction of the first row of beads 131 is counterclockwise, the preset rotation direction of the second row of beads 131 is clockwise.

For example, referring to fig. 16, in two adjacent rows of beads 131, the first row of beads 131 and the second row of beads 131, the predetermined rotation direction of the first row of beads 131 is counterclockwise, and the predetermined rotation direction of the second row of beads 131 is clockwise. In two rows of the beads 131 adjacent to the second row of the beads 131 and the third row of the beads 131, the preset rotation direction of the second row of the beads 131 is clockwise, and the preset rotation direction of the third row of the beads 131 is counterclockwise. Among the two adjacent rows of beads 131, the third row of beads 131 and the fourth row of beads 131, the preset rotation direction of the third row of beads 131 is counterclockwise, and the preset rotation direction of the fourth row of beads 131 is clockwise.

Therefore, by setting that the preset rotation direction of one row of the lamp beads 131 in any two adjacent rows of the lamp beads 131 of the display module 13 is opposite to the preset rotation direction of the other row of the lamp beads 131, the color uniformity and consistency of different display areas of the display module 13 can be improved, so that a user can obtain consistent color impression when looking at the display picture of the display module 13 in all directions, and even if the installation directions of the left and right LED display modules 100 are opposite, color difference does not exist when controlling the left and right LED display modules 100 to display, the display effect can be improved, and the user viewing experience can be improved.

In some embodiments, in two adjacent rows of beads 131, the preset rotation direction of the first row of beads 131 is opposite to the preset rotation direction of the second row of beads 131. The first row of beads 131 and the second row of beads 131 are two adjacent rows of beads 131.

The preset rotation direction of the first row of beads 131 means that, in two adjacent beads 131 of the first row of beads 131, the front bead 131 rotates by a preset angle according to the preset rotation direction with the center of the bead as a rotation axis, and then translates by a preset distance to overlap with the rear bead 131. The preset rotation direction of the second row of beads 131 is the same, and will not be described here again.

Here, the first row of beads 131 and the second row of beads 131 are used to represent any two adjacent rows of beads 131 in the display module 13, that is, in the display module 13, it is satisfied that the preset rotation direction of one row of beads 131 in any two adjacent rows of beads 131 is opposite to the preset rotation direction of the other row of beads 131.

For example, the display module 13 includes four rows of beads 131, wherein the first row of beads 131 and the second row of beads 131 are two adjacent rows of beads 131, and the preset rotation direction of the first row of beads 131 is opposite to the preset rotation direction of the second row of beads 131, and the preset rotation direction of the second row of beads 131 and the preset rotation direction of the third row of beads 131 are opposite to the preset rotation direction of the third row of beads 131, and the preset rotation direction of the third row of beads 131 and the preset rotation direction of the fourth row of beads 131 are opposite to the preset rotation direction of the fourth row of beads 131.

When the preset rotation direction of the first row of beads 131 is clockwise, the preset rotation direction of the second row of beads 131 is counterclockwise, and when the preset rotation direction of the first row of beads 131 is counterclockwise, the preset rotation direction of the second row of beads 131 is clockwise.

For example, with continued reference to fig. 16, in two rows of beads 131 adjacent to the first row of beads 131 and the second row of beads 131, the predetermined rotation direction of the first row of beads 131 is counterclockwise, and the predetermined rotation direction of the second row of beads 131 is clockwise. In two rows of beads 131 adjacent to the second row of beads 131 and the third row of beads 131, the preset rotation direction of the second row of beads 131 is clockwise, and the preset rotation direction of the third row of beads 131 is counterclockwise. Of the two rows of beads 131 adjacent to the third row of beads 131 and the fourth row of beads 131, the preset rotation direction of the third row of beads 1231 is counterclockwise, and the preset rotation direction of the fourth row of beads 131 is clockwise.

Therefore, by setting that the preset rotation direction of one row of the lamp beads 131 in any two adjacent rows of the lamp beads 131 of the display module 13 is opposite to the preset rotation direction of the other row of the lamp beads 131, the color uniformity and consistency of different display areas of the display module 13 can be improved, so that a user can obtain consistent color impression when looking at the display picture of the display module 13 in all directions, and even if the installation directions of the left and right LED display modules 100 are opposite, color difference does not exist when controlling the left and right LED display modules 100 to display, the display effect can be improved, and the user viewing experience can be improved.

It can be understood that, since the input interface module 11 of the LED display module 100 supports forward and backward insertion with the external interface, and when the installation directions of the LED display modules 100 on the left and right sides are opposite, no color difference exists when the LED display modules 100 on the left and right sides are controlled to display, the LED display modules 100 do not need to be distinguished from each other, and the LED display modules 100 can be used for displaying pictures after being assembled by using a plurality of identical LED display modules 100.

As another aspect of the embodiments of the present utility model, the embodiments of the present utility model provide a display apparatus including the LED display module set as described above.
