Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a multi-functional LED display device structure. Background Technology

[0002] As electronic devices continue to become smaller and thinner, such as mobile phones, tablets, and wearable devices, smaller light sources are needed to adapt to the limitations of internal space in miniaturized electronic products.

Detailed Implementation

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] refer to Figure 1-3 A multi-functional LED display device structure includes a support plate 1, at least one first display unit 2, at least one second display unit 3, and two clearance holes 4. The support plate 1 is the basic support structure for the entire display device. The support plate 1 can be made of epoxy resin fiberglass board, which has good insulation properties, mechanical strength, and heat resistance, and can meet the working environment requirements of LED display devices. The first display unit 2 is located on one side of the support plate 1, and the second display unit 3 has the same structure as the first display unit 2 and is located on the other side of the support plate 1. The display function of the multi-functional LED display device structure can be realized by the light emitted by the first display unit 2 and the second display unit 3. The number of the first display unit 2 and the second display unit 3 can be set according to the actual situation. The two clearance holes 4 are symmetrically arranged in the middle of the support plate 1, and fixing screws are provided in the two adjacent clearance holes 4. The circuit board can be fixed inside the electronic product with screws without leaving a gap between the two adjacent multi-functional LED display devices, thereby improving the integration of the light source inside the electronic product and meeting the installation requirements of miniaturized electronic products.

[0032] In some embodiments, the clearance hole 4 can be a semi-circular hole, which can be adapted to the screw. While satisfying the screw fixing, it can reduce the gap of the support plate 1, maintain good structural strength, and its stress distribution is relatively uniform, making it less prone to stress concentration.

[0033] In some embodiments, the first display unit 2 includes a pad 21, a light-emitting chip group 22, and four pins 23. The pad 21 is disposed on the top surface of one side of the support plate 1. The light-emitting chip group 22 can be soldered onto the pad 21. The four pins 23 are symmetrically disposed at both ends of the support plate 1, and all four pins 23 are connected to the pad 21. The four pins 23 are electrically connected to the external circuit, thereby enabling the light-emitting chip group 22 to work. The light-emitting chip group 22 may include a red light chip, a blue light chip, and a green light chip, which can be adjusted according to the actual situation. The connection structure between the pad 21, the light-emitting chip group 22, and the four pins 23 is prior art and will not be described in detail here.

[0034] In some embodiments, the first display unit 2 further includes a packaging cover 24 and a packaging mold 25. The packaging cover 24 is disposed on the top surface of one side of the support plate 1, and the packaging cover 24 contains a light-emitting chip group 22 and a pad 21. The packaging cover 24 has a packaging groove in the middle. The packaging mold 25 can be formed by filling the packaging groove with epoxy resin and solidifying it. Epoxy resin has good light transmittance, insulation and weather resistance. The packaging cover 24 and the packaging mold 25 can protect the light-emitting chip group 22 and the pad 21, and improve the stability and reliability of the display device.

[0035] In some embodiments, the support plate 1 includes a first support portion 11, a second support portion 12, and a connecting portion 13. The first support portion 11 is provided with a first display unit 2, the second support portion 12 is provided with a second display unit 3, and the connecting portion 13 is disposed between the first support portion 11 and the second support portion 12. Both ends of the connecting portion 13 are provided with clearance holes 4. The connecting portion 13 can make the first support portion 11 and the second support portion 12 form a whole, thereby enhancing the installation strength of the display device structure on the circuit board and improving its stability.

[0036] In some embodiments, a metal reinforcing member 5 is also included. The metal reinforcing member 5 is embedded in the connecting portion 13, and the two sides of the metal reinforcing member 5 are respectively embedded in the first support portion 11 and the second support portion 12. It can be tightly combined with the support plate 1 to form a stable overall structure, thereby improving the overall strength of the display device structure.

[0037] In some embodiments, the metal reinforcing member 5 includes a square metal plate 51, two arc-shaped grooves 52, two connecting plates 53, and two reinforcing grooves 54. The metal plate 51 is embedded in the support plate 1, which can enhance the overall strength of the support plate 1. The two arc-shaped grooves 52 are symmetrically arranged at both ends of the metal plate 51, which can be adapted to the avoidance hole 4 to achieve effective avoidance of screws. The connecting plate 53 is arranged in the middle of the arc-shaped groove 52, which can increase the connection area between the metal plate 51 and the support plate 1, thereby further enhancing the stability of the structure. The two reinforcing grooves 54 are symmetrically arranged on both sides of the metal plate 51, which can reinforce the material that can be filled in the groove 54 with the support plate 1, thereby forming a limiting plate structure in the reinforcing groove 54, thereby increasing the connection area between the metal plate 51 and the support plate 1, and further enhancing the stability of the structure.

[0038] In some embodiments, the reinforcing groove 54 may be a rounded triangular groove that can be adapted to the arc-shaped groove 52 to ensure the uniformity of the distance between the reinforcing groove 54 and the arc-shaped groove 52, thereby ensuring the structural strength of the metal reinforcement 5.

[0039] In some embodiments, the encapsulation cover 24 of the first display unit 2 has a notch on the side away from the second display unit 3. The notch allows the electrodes on the display device structure to be marked, thereby facilitating installation.

[0040] The specific working principle is as follows:

[0041] During installation, multiple pins 23 are soldered onto the circuit board, which allows the multi-in-one LED display device structure to be soldered and fixed on the circuit board. At this time, the two sides of two adjacent multi-in-one LED display device structures are tightly fitted, so that the two adjacent clearance holes 4 are close to each other, increasing the size of the hole between the two adjacent multi-in-one LED display device structures. Screws can pass through the hole to fix the circuit board to the electronic product to be fixed, thereby realizing the installation of the light source on the micro electronic product.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
