The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

Furthermore, the terms "first," "second," and the like, are used primarily to distinguish one device, element, or component from another (the specific nature and configuration may be the same or different), and are not used to indicate or imply the relative importance or number of the indicated devices, elements, or components.

As shown in fig. 1, the dashed arrow in fig. 1 shows the course of the current I. In the related art, the display module 1 includes a substrate 11 and a line 12 disposed on the substrate 11, the line 12 includes a power interface terminal 121 and a ground interface terminal 122, the power interface terminal 121 and the ground interface terminal 122 are located on the same side of the substrate 11, and the plurality of LED lamps 131 are connected in series through the line 12. Since each LED lamp 131 is connected to the power interface end 121 and the ground interface end 122 through the line 12, the current I of each LED lamp 131 needs to pass through the power interface end 121 and the ground interface end 122, and since the power interface end 121 and the ground interface end 122 are located on the same side of the substrate 11, when the display assembly 1 is powered on, a larger current I may pass through the side of the substrate 11 where the power interface end 121 and the ground interface end 122 are located, so that the temperature of the side of the substrate 11 where the power interface end 121 and the ground interface end 122 are located is higher, which may cause the service life of the LED lamp 131 close to the side of the substrate 11 where the power interface end 121 and the ground interface end 122 are located to be shortened due to heating, thereby affecting the service life of the display assembly 1.

In addition, since the temperature of the side of the substrate 11 where the power interface end 121 and the ground interface end 122 are disposed is high, and the temperature of the side of the substrate 11 away from the power interface end 121 and the ground interface end 122 is low, the temperature distribution of the display module 1 is not uniform, and the LED lamp 131 is extremely sensitive to temperature, which may cause the luminous performance of the LED lamp 131 close to the power interface end 121 and the ground interface end 122 and the luminous performance of the LED lamp 131 away from the power interface end 121 and the ground interface end 122, such as luminous efficiency, luminous color (wavelength), color temperature, etc., to be different, thereby causing the image displayed by the display module 1 to be distorted or to be poor in definition, and greatly affecting the use effect.

Furthermore, since the power interface end 121 and the ground interface end 122 are disposed on the same side of the substrate 11, the distance between the power interface end 121 and the ground interface end 122 is short, and when the power interface end 121 and the ground interface end 122 are respectively connected to power and ground, the two lines 12 are close to each other, which may cause interference.

Based on this, the present application discloses a display assembly 1, the power interface terminal 121 and the ground interface terminal 122 of the line 12 of the display assembly 1 are distributed on different sides of the substrate 11. By adopting the manner that the power interface end 121 and the ground interface end 122 are distributed on different sides of the substrate 11, heat generated by the power interface end 121 and the ground interface end 122 can be distributed on different sides of the substrate 11, so that the uniformity of temperature distribution of the display assembly 1 is improved, and the light emitting performance and the service life of the LED lamp 131 are improved.

The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.

Referring to fig. 2 to 4, the dashed arrows in fig. 3 and 4 show the trend of the current I. The utility model discloses a display assembly 1 in a first aspect, which comprises a substrate 11 and an LED lamp group 13, wherein the substrate 11 is a transparent substrate, at least one line 12 is arranged on the surface of the substrate 11, the line 12 comprises a power interface end 121 and a ground interface end 122, the power interface end 121 and the ground interface end 122 are positioned on different sides of the substrate 11, the LED lamp group 13 comprises a plurality of LED lamps 131, and the plurality of LED lamps 131 are arranged on the substrate 11 at intervals and are electrically connected in series through the line 12.

In the display module 1 of the embodiment of the utility model, the power interface end 121 and the ground interface end 122 of the line 12 are disposed at different sides of the substrate 11, so that when the display module 1 is powered on, the power interface end 121 and the ground interface end 122 generate heat at different sides of the substrate 11, and thus heat of the power interface end 121 and heat of the ground interface end 122 can be dispersed at different sides of the substrate 11, so that the heat distribution of the display module 1 is uniform, and the situations that the service life of the LED lamp 131 is short and the luminescence performance (such as light efficiency, light color, color temperature, and the like) is poor due to uneven heat distribution are avoided, so that the service life and the luminescence performance of the LED lamp 131 can be improved, and further the service life and the display effect of the display module 1 are favorably improved. In addition, since the power interface end 121 and the ground interface end 122 are located on different sides of the substrate 11, a distance between the power interface end 121 and the ground interface end 122 is relatively large, so that when the power interface end 121 and the ground interface end 122 of the display module 1 are connected, the line 12 connected to the power interface end 121 and the line 12 connected to the ground interface end 122 are not easily interfered, thereby being beneficial to improving the wiring safety of the display module 1.

Since the substrate 11 is a transparent substrate, the display module 1 can also be a transparent display module, and therefore, the display module 1 can be applied to scenes which need to display images and do not affect the observation of their own scenes, such as glass show windows, building curtain walls, glass fences, interior decorations, and the like, so that the display module 1 can achieve a display effect and does not affect the observation of the scenes behind the display module 1. For example, in a showcase for displaying products, the display assembly 1 is required to display images to perform functions of introducing or publicizing the products, and a customer is required to be able to observe specific forms of the products in the showcase, and therefore, the transparent display assembly 1 is required to meet the use requirement. Of course, the display module 1 can be applied to other fields.

Alternatively, the substrate 11 may be a PET (Polyethylene terephthalate) film or a COP (cyclic Olefin copolymer) film. The transparency of the PET film and the COP film is high, so that the display effect of the display component 1 is improved.

Alternatively, the thickness H1 of the substrate 11 is between 50 μm and 200 μm, illustratively the thickness of the substrate 11 is 50 μm, 80 μm, 100 μm, 130 μm, 150 μm, 180 μm, 200 μm, and the like. The thickness H1 of the substrate 11 is controlled between 50 μm and 200 μm, which is beneficial to reducing the production difficulty of the display module 1. Since the LED lamp 131 is required to be soldered to the substrate 11 during the assembly of the display module 1, when the thickness H1 of the substrate 11 is less than 50 μm, the display module 1 may be deformed seriously due to the high temperature of soldering, and the display module 1 may be deformed as a whole, or even the display module 1 may not be used, so that the yield of the display module 1 is low and the production difficulty is high. When the thickness H1 of the substrate 11 is greater than 200 μm, the substrate 11 is difficult to manufacture, thereby increasing the difficulty of manufacturing.

Alternatively, the substrate 11 may be an elongated substrate, that is, the dimension of the substrate 11 in the length direction is greater than the dimension of the substrate 11 in the width direction, and the plurality of LED lamps 131 may be sequentially arranged at intervals along the length direction of the substrate 11, so as to facilitate the plurality of LED lamps 131 to be serially disposed on the substrate 11.

In some embodiments, the lines 12 are mesh lines. By providing the grid lines 12, the light transmittance of the display module 1 is improved, thereby improving the display effect. When forming the wiring 12 on the substrate 11, the following method may be employed:

in an alternative embodiment, a metal layer is formed on the substrate 11 by electroplating, and then the grid lines are formed by etching. The metal layer is formed on the substrate 11 by electroplating, so that the processing cost of the metal layer is lower.

In another alternative embodiment, a metal layer is formed on the substrate 11 by sputtering, and then the grid lines are formed by etching. The metal layer is formed on the substrate 11 by sputtering, so that the thickness of the metal layer is more uniform, the thickness of the grid line is more uniform, and the accuracy of the grid line formed by etching is higher.

In some embodiments, the display module 1 includes a plurality of LED lamp sets 13, the surface of the substrate 11 is provided with a plurality of lines 12, a plurality of LED lamps 131 of the same LED lamp set 13 are connected in series to one line 12, and the plurality of LED lamp sets 13 are connected in parallel. By providing a plurality of LED lamp sets 13 and connecting the plurality of LED lamp sets 13 in parallel, when one of the LED lamp sets 13 fails, the remaining LED lamp sets 13 connected in parallel are not affected. Alternatively, the number of LED lamp groups may be 2, 3, 4 or more.

Alternatively, the thickness H2 of the wiring 12 ranges between 0.050 μm and 5 μm in a direction perpendicular to the substrate 11. Illustratively, the thickness H2 of the trace 12 may be 0.05 μm, 0.1 μm, 0.5 μm, 1 μm, 3 μm, 5 μm, or the like. When the thickness H2 of the wire 12 is less than 0.050 μm, the wire 12 is insufficient in strength, which may cause a risk that the wire 12 is broken to cause an open circuit, and further, the thickness H2 of the wire 12 is thin to cause a wire resistance to be large, resulting in a large amount of heat generation upon energization. When the thickness H2 of the circuit 12 is greater than 5 μm, the metal layer with a thickness of 5 μm or more is formed on the substrate 11 by plating or sputtering, which is difficult to process, the uniformity of the metal layer is poor, and the material cost is high. Therefore, by controlling the thickness H2 of the line 12 to be between 0.050 μm and 5 μm, not only can the strength of the line 12 be ensured to ensure the reliability of the line 12, but also the production cost and the production difficulty of the line 12 can be reduced.

As shown in fig. 3, in some embodiments, the power interface end 121 and the ground interface end 122 are respectively disposed on two adjacent sides of the substrate 11. In this way, the distance between the power interface end 121 and the ground interface end 122 is small, so that when the power interface end 121 and the ground interface end 122 of the display assembly 1 are connected to each other through the line 12, the connection of the line 12 is more convenient.

In other embodiments, as shown in fig. 4, the power interface end 121 and the ground interface end 122 are respectively disposed on two opposite sides of the substrate 11. Like this, power interface end 121 and ground wire interface end 122's distance is great to the heat that produces when further turning on this display module 1 disperses, thereby promotes the homogeneity of this display module 1 heat distribution, with life and the luminous performance that improves LED lamp 131, and then is favorable to improving this display module 1's life and display effect.

In an alternative embodiment, the power interface terminal 121 and the ground interface terminal 122 are respectively disposed on two opposite sides of the substrate 11 along the width direction of the substrate 11. Thus, the length from the power interface end 121 to the ground interface end 122 is shorter, the number of the LED lamps 131 connected in series is smaller, and when part of the LED lamps 131 are damaged, the repair and replacement are more convenient.

In another alternative embodiment, as shown in fig. 4, the power interface end 121 and the ground interface end 122 are respectively disposed on two opposite sides of the substrate 11 along the length direction of the substrate 11. Like this, the distance between power interface end 121 and the ground wire interface end 122 is bigger to further disperse the heat that produces when this display module 1 circular telegram, with the homogeneity that improves this display module 1 heat distribution, and then improve the life and the luminous performance of LED lamp 131, be favorable to improving this display module 1's life and display effect. In addition, the power interface end 121 and the ground interface end 122 are respectively disposed on two opposite sides of the substrate 11 along the length direction of the substrate 11, so that the distance between the power interface end 121 and the ground interface end 122 is larger, and then, more LED lamps 131 can be connected in series from the power interface end 121 to the ground interface end 122, that is, one LED lamp group 13 can include more LED lamps 131, so that the number of the LED lamp groups 13 that need to be disposed in the display module 1 can be reduced, thereby facilitating the assembly of the display module 1, and the layout of the circuit 12 is simpler.

In some embodiments, the plurality of LED lamps 131 are sequentially spaced along the direction from the power interface end 121 to the ground interface end 122, so that the arrangement of the wires 12 on the substrate 11 is more regular. Of course, in other embodiments, a plurality of LED lamps 131 may also be arranged in an S-shaped curve from the power interface end 121 to the ground interface end 122 (for example, as shown in fig. 5), so that one LED lamp set 13 may be connected in series with more LED lamps 131, so that the display module 1 may be provided with a smaller number of LED lamp sets 13 to facilitate the assembly of the display module 1.

As shown in fig. 4, in some embodiments, the distance L between two adjacent LED lamps 131 ranges from 5mm to 200mm along the arrangement direction of the LED lamps 131. Illustratively, the spacing L between two adjacent LED lamps 131 may be 5mm, 10mm, 30mm, 50mm, 80mm, 100mm, 150mm, 200mm, or the like. The distance L between two adjacent LED lamps 131 is controlled to be 5 mm-200 mm, so that the resolution and the light transmittance of the display assembly 1 are high, and the display effect of the display assembly 1 can be improved. When the distance L between two adjacent LED lamps 131 is greater than 200mm, the resolution of the display module 1 is reduced, thereby affecting the display effect of the display module 1. When the distance L between two adjacent LED lamps 131 is less than 5mm, the density of the LED lamps 131 is high, thereby reducing the transmittance of the display module 1 and affecting the display effect of the display module 1.

Note that the distance between two adjacent LED lamps 131 refers to a minimum distance L between two adjacent LED lamps 131.

In some embodiments, the LED lamp 131 is a patch type LED lamp 131 having a chip, so that received data can be processed. In this way, data reception and processing of the LED lamp 131 can be realized through one signal line 14, and the LED lamp 131 does not need to be connected with other control components through other lines to realize data processing, so that the wiring manner of the display module 1 can be simplified.

In an optional embodiment, the substrate 11 is further provided with a signal line 14, the LED lamp 131 includes four pins, the four pins are a first pin 132, a second pin 133, a third pin 134, and a fourth pin 135, respectively, the first pin 132 is used for receiving data, the second pin 133 is used for outputting data, the third pin 134 is used for power connection, the fourth pin 135 is used for ground connection, and the second pin 133 and the fourth pin 135 of two adjacent LED lamps 131 are connected in series through the signal line 14. The LED lamp 131 with four pins is adopted, so that the LED lamp 131 can display various colors, the cost is low, and the control of the production cost of the display assembly 1 is facilitated.

Specifically, along the serial connection direction of the LED lamps 131, two adjacent LED lamps 131 are respectively called a first LED lamp 13a and a second LED lamp 13b, a first pin 132 of the second LED lamp 13b is connected to a second pin 133 of the first LED lamp 13a through the signal line 14, and a third pin 134 and a fourth pin 135 are respectively connected to the power interface terminal 121 and the ground interface terminal 122. In this way, the second LED lamp 13b receives and processes the output data of the first LED lamp 13a, and then outputs the processed data through the second pin 133 of the second LED lamp 13b, so as to implement data processing and transmission, thereby controlling the LED lamp 131 to emit light.

It is understood that, for a plurality of LED lamps 131 connected in series, when one of the LED lamps 131 fails, data cannot be transmitted to the following LED lamp 131, and then the following LED lamp 131 cannot emit light normally. For example, when the first LED lamp 13a fails, the data of the first LED lamp 13a cannot be transmitted to the second LED lamp 13b, that is, the first pin 132 of the second LED lamp 13b cannot receive the input data, so that the second LED lamp 13b and the remaining LED lamps 131 behind the second LED lamp 13b cannot emit light, which may affect the display effect of the display assembly 1.

In another alternative embodiment, as shown in fig. 6 and 7, the LED lamp 131 has six pins, i.e., a first pin 132 and a second pin 133, a third pin 134, a fourth pin 135, a fifth pin 136, and a sixth pin 137. The first pin 132 is used for receiving input data of the first LED lamp 13a, the second pin 133 is used for backing up output data of the first LED lamp 13a, the third pin 134 is used for receiving output data of the first LED lamp 13a, the fourth pin 135 is used for outputting processed data to the next LED lamp 131, and the fifth pin 136 and the sixth pin 137 are respectively used for power connection and grounding.

Illustratively, for two adjacent LED lamps 131 connected in series, the first pin 132 of the second LED lamp 13b is connected to the second pin 133 of the first LED lamp 13a, and the third pin 134 of the second LED lamp 13b is connected to the fourth pin 135 of the first LED lamp 13 a.

When the first LED lamp 13a is not failed, the fourth pin 135 of the first LED lamp 13a transmits its output data to the third pin 134 of the second LED lamp 13b, the second LED lamp 13b controls its light emission according to the processing of the input data, and the processed data is output through the fourth pin 135.

When the first LED lamp 13a fails, the second pin 133 of the first LED lamp 13a transmits the backup input data to the first pin 132 of the second LED lamp 13b (i.e., the first LED lamp transmits its input data to the first pin of the second LED lamp 13b through the third pin 134 and the second pin 133 thereof, i.e., the second pin 133 and the third pin 134 are connected in series for data transmission), the second LED lamp 13b controls its light emission according to the input data, and the processed data is output through the fourth pin 135.

When the second LED lamp 13b fails, the second LED lamp 13b outputs the backup output data of the first LED lamp 13a to the subsequent LED lamp 131 through the second pin 133 thereof (i.e., the output data of the first LED lamp 13a is output to the subsequent LED lamp 131 through the fourth pin 135 of the first LED lamp 13a, the third pin 134 of the second LED lamp and the second pin 133 thereof, i.e., the second pin 133 of the second LED lamp 13b, the third pin 134 and the fourth pin 135 of the first LED lamp 13a are connected in series and used for data transmission), so that the subsequent LED lamp 131 can receive the input data, and thus can normally emit light.

Therefore, when one of the LED lamps 131 fails, the subsequent LED lamp 131 can still emit light normally, so that the influence on the display effect of the LED lamp 131 group 13, that is, the influence on the entire display effect of the display module 1 is reduced.

In the display module 1 according to the first aspect of the embodiment of the present invention, the power interface end 121 and the ground interface end 122 of the display module 1 are located at different sides of the substrate 11, so that heat generated by the power interface end 121 and the ground interface end 122 can be distributed at different sides of the substrate 11, so that the heat distribution of the display module 1 is uniform during operation, and the condition that the light emitting effect of the LED lamp 131 is affected by heat concentration is avoided.

Referring to fig. 8, a second aspect of the present invention discloses a display screen 2, which includes the display module 1 according to the first aspect.

Since the display panel 2 of the second aspect of the present invention includes the display module 1 of the first aspect, the display panel 2 has all the technical effects of the display module 1 of the first aspect, that is, the display panel 2 has uniform heat distribution during operation, long service life and good light emitting performance.
