As shown in fig. 1-7, the present embodiment provides a transparent display screen 1000, which includes a transparent motherboard 3 and more than one transparent light emitting module 100 mounted on the transparent motherboard 3; the transparent motherboard 3 is provided with a transmission circuit (not shown in the figure) for providing power and signals for the transparent light emitting module 100; the transparent motherboard 3 and the transparent light-emitting module 100 integrally show a transparent display effect;

The transparent light emitting module 100 is provided with a driving circuit (not shown in the figure) and a plurality of light emitting pixels 2 arranged in an array, wherein the light emitting pixels 2 comprise a driving chip and a light emitting wafer; each of the light emitting pixels 2 is connected to the driving circuit connected to a transmission circuit of the transparent motherboard 3; so as to electrically connect each transparent light emitting module 100 to the transparent motherboard 3, and provide power and signals for the light emitting pixels 2 on the transparent light emitting module 100.

The specific implementation of the transparent mother substrate 3 and the transparent light emitting module 100 in the present application is not particularly limited as long as it can visually appear to achieve a transparent effect, and then a transmission circuit and a driving circuit are respectively formed thereon, and the transmission circuit and the driving circuit are electrically connected so that it can supply power and signals to the light emitting pixels 2 through the transmission circuit and the driving circuit. The transparent light emitting module 100 generally includes a module substrate 1, and the light emitting pixels 2 are disposed on the module substrate 1, and the module substrate 1 may have a layered structure with more than one layer. In general, the transparent display effect of the transparent motherboard 3 and the module substrate 1 can be achieved by using a transparent material as a base material or carrier. For example, the transparent motherboard 3 is a transparent glass plate, and the transmission circuit is disposed on the transparent glass plate. The transparent light emitting module 100 includes a module substrate 1 that is a transparent substrate, and the driving circuit is disposed on the transparent substrate; the transparent substrate may be a transparent glass plate or a transparent film, and the array of light emitting pixels 2 is arranged on a driving circuit of the transparent substrate.

The transparent motherboard 3 and the transparent light-emitting module 100 may be realized by providing a light-transmitting area and a non-light-transmitting area on a non-light-transmitting substrate or carrier, and the transparent motherboard and the transparent light-emitting module can realize a transparent effect by the light-transmitting area, and a driving circuit and a transmission circuit are provided on the non-light-transmitting area.

In this example, the non-transparent material is used as a base material or a carrier, and the projection of the light-transmitting area on the transparent light-emitting module 100 is located in the light-transmitting area on the transparent motherboard 3; meaning that the light-transmitting areas on the transparent light-emitting module 100 are not blocked by the non-light-transmitting areas on the transparent motherboard 3. Preferably, light holes corresponding to each other are arranged on the transparent motherboard 3 and the transparent light emitting module 100 in an array manner, and a non-light-transmitting area is formed in an area except the light holes; taking the transparent light emitting module 100 as an example, generally, the larger the area ratio of the light transmitting area to the non-light transmitting area is, the higher the transparency of the transparent light emitting module 100 is, and the better the permeability is. For distinction, the light holes on the transparent light emitting module 100 are referred to as first light holes 11; the light transmission holes on the transparent master plate 3 are called second light transmission holes 31. In the application, the transparent light-emitting module 100 is made of non-transparent material, and the transparent light-emitting module 100 and the transparent motherboard 3 are both printed circuit boards and at least comprise two circuit layers; the circuit layer on the transparent motherboard 3 forms the transmission circuit and is used for providing power and signals for the module substrate; the circuit layer on the transparent light emitting module 100 forms a driving circuit, and the driving circuit provides power and signals for each of the light emitting pixels 2. For example, the transparent motherboard 3 is preferably a printed wiring board directly, and is composed of at least two wiring layers, and the wiring layers thereon form a driving circuit that supplies power and signals to each of the light emitting pixels 2. Similarly, the transparent motherboard 3 is made of non-transparent material, for example, it is generally a printed circuit board, and is composed of at least two circuit layers, and the circuit layers thereon form a transmission circuit, and the transmission circuit is used for connecting with a driving circuit to provide power and signals for each of the light emitting pixels 2.

The size of the light-transmitting hole can be optimally designed according to actual requirements in the production process, and balance can be found between keeping transparent and ensuring the display performance of the product. It will be apparent to those skilled in the art that the present invention may be practiced without some of these specific details.

The area outside the light holes forms a non-light-transmitting area; the design of the light-transmitting area and the non-light-transmitting area on the transparent motherboard 3 in this example may not necessarily be in a one-to-one mapping relationship with the light-transmitting holes and the non-light-transmitting areas on the transparent light-emitting module 100, but only needs to be set so that the projection of each light-transmitting hole on the transparent light-emitting module 100 is located in the light-transmitting area on the transparent motherboard 3. Since the light emitting pixels 2 do not need to be arranged in an array on the transparent mother substrate 3, only a small non-light-transmitting area is required for arranging the transmission circuit, and thus the light-transmitting area on the transparent mother substrate 3 can be large or small. For example, as one embodiment, the light-transmitting region of the transparent mother substrate 3 includes second light-transmitting holes 31 arranged in an array thereon; the non-light-transmitting area is formed in the area outside the second light-transmitting hole 31; the second light holes 31 are arranged in one-to-one correspondence with the first light holes 11 and the second light holes 21.

As shown in the figure, the light emitting pixels 2 in this example may be LED beads integrated with a lamp cup.

As shown in fig. 2 and 3, the transparent light emitting module 100 is provided with an electrical connection portion 12; as shown in fig. 4, the transparent motherboard 3 is provided with a module connection portion 33, and the module connection portion 33 on the transparent motherboard 3 is electrically connected with the electrical connection portion 12 on the module substrate to electrically connect the driving circuit on the transparent light emitting module 100 and the transmission circuit on the transparent motherboard 3, and power and signals are input from the transparent motherboard 3 to the transparent light emitting module 100.

Specifically, the electrical connection portion 12 on the transparent light emitting module 100 and the module connection portion 33 on the transparent motherboard 3 are respectively provided with a plurality of power connection structures and signal connection structures.

In this example, the electrical connection portion 12 includes a plurality of power connection structures and signal connection structures in the non-light-transmitting region. The power supply connection structure is a first power supply connection hole, and the signal connection structure is a first signal connection hole. The power connection structure and the signal connection structure of the electrical connection portion 12 are concentrated or dispersed at any position of the non-light-transmitting area on the transparent light-emitting module 100, and preferably, the power connection structure and the signal connection structure of the electrical connection portion 12 are concentrated or dispersed at the corner position or the edge of the module substrate 1. In this example, the power connection structure and the signal connection structure of the electrical connection portion 12 are arranged in a concentrated manner, and in this example, as shown in fig. 2 and 3, at least one of the first light holes 11 of the transparent light emitting module 100 is arranged as an opaque structure as the electrical connection portion 12. In the same way, in this example, as shown in fig. 4, a non-light-transmitting structure is provided as a module connection portion 33 in one or more second light-transmitting holes 31 in the light-transmitting motherboard 3, and the electrical connection portion 12 of the light-transmitting substrate 1 and the module connection portion 33 in the light-transmitting motherboard 3 are correspondingly connected.

In this example, the power connection structure on the transparent light emitting module 100 is a first power connection hole, and the signal connection structure is a first signal connection hole; the power supply connection structure on the transparent motherboard 3 is a second power supply connection hole, and the signal connection structure is a second signal connection hole; as shown in fig. 5, fig. 7, etc., the first power connection hole and the second power connection hole, and the first signal connection hole and the second signal connection hole are all connected by an electrical connector 331. In this example, the electrical connector 331 is a metal pin or a metal column connector. Welded by the metal needle-like or metal column-like connection. Of course, the power connection structure and the signal connection structure on the module substrate 1, and the power connection structure and the signal connection structure on the light-transmitting template 3 may be other electrical connection methods. So long as it ultimately enables electrical connection of the module substrate 1 and the light transmissive template 3.

In this way, the mechanical strength of the transparent motherboard 3 and the transparent light emitting module 100 can be enhanced while the electrical connection between the transparent motherboard 3 and the transparent light emitting module 100 is achieved.

Since each of the light emitting pixels 2 is provided with a driving chip to directly drive the light emitting chip, the internal circuit of the transparent light emitting module 100 becomes very simple, and in general, all the light emitting pixels 2 in the transparent light emitting module 100 can be connected in series with 1 to 2 signal lines except for the power supply line. The N transparent light emitting modules 100 are mounted on the transparent motherboard 3, and the number of signal lines required on the transparent motherboard 3 can be as small as N and at most 2N, so that no additional electronic components are required to be mounted on the transparent light emitting modules 100 or the transparent motherboard 3, and the whole product becomes clean and tidy.

The transparent light emitting module 100 of the present technology is easy to produce and maintain because of its smaller size, and the transparent motherboard 3 has no mounted components, and is simple to manufacture and low in cost, and the combination of the two components will reduce the quality risk of the product in the production and application processes. Particularly, for the LED lamp beads using the built-in driving chips with fixed addresses, only the addresses of the light emitting pixels 2 mounted in the transparent light emitting module 100 need to be managed, and the addresses of the light emitting pixels 2 at different positions in the screen in different projects need not be considered.
