With reference to fig. 1 to 4, the LED element 5 is disposed on the patterned conductive structure of the second transparent conductive layer 4. Illustratively, the LED element 5 includes six leads, and the shape and position of the patterned conductive structure in the second transparent conductive layer 4 may be set corresponding to the six leads of the LED element 5. By way of example, the LED elements 5 may be arranged on the patterned conductive structure of the second transparent conductive layer 4 by means of conductive silver glue, that is, the first power signal input pin VCC of the LED device 5 is disposed on the patterned conductive structure 41 of the second conductive layer through the conductive silver paste, the second power signal input pin VDD is disposed on the patterned conductive structure 42 of the second conductive layer through the conductive silver paste, the control data signal output pin DO is disposed on the patterned conductive structure 43 of the second conductive layer through the conductive silver paste, the control data signal input pin DIN is disposed on the patterned conductive structure 44 of the second conductive layer through the conductive silver paste, the ground pin GND is disposed on the patterned conductive structure 45 of the second conductive layer through the conductive silver paste, and the auxiliary data input pin BIN is disposed on the patterned conductive structure 46 of the second conductive layer through the conductive silver paste.
With reference to fig. 1 to 4, the patterned conductive structure in the second transparent conductive layer 4 is electrically connected to the patterned conductive structure in the first transparent conductive layer 2, the corresponding pins of the driving chip 6 located in the non-display area NAA of the transparent LED display panel may be electrically connected to the corresponding pins of the first transparent conductive layer 2, the pins of the driving chip 6 are electrically connected to the corresponding pins of the LED element 5 through the patterned conductive structure in the first transparent conductive layer 2 and the patterned conductive structure in the second transparent conductive layer 4, so as to provide electrical signals required for the operation of the LED element 5 to the corresponding pins of the LED element 5, and the transparent LED display panel implements a display function.
For example, the auxiliary data signal input pin of the nth LED element may be electrically connected to the first power signal input pin of the (n + 1) th LED element and the control data signal output pin of the (n + 2) th LED element along the row direction or the column direction of the arrangement of the LED elements, so that the LED elements in the transparent LED display panel can implement the breakpoint continuous transmission function. For example, in conjunction with fig. 1 to 4, it may be arranged that the auxiliary data signal input pin BIN of the first LED element 5 is electrically connected to the first power signal input pin VCC of the second LED element 5 and the control data signal output pin DO of the third LED element 5 along the row direction of the arrangement of the LED elements 5.
With reference to fig. 1 to 4, the LED element 5 includes an LED chip and a control chip, the first power signal input pin VCC is used for inputting a power signal for supplying power to the control chip, the second power signal input pin VDD is used for inputting a power signal for supplying power to the LED chip, after the LED element 5 is reset by power-on, the control data signal input pin DIN receives data transmitted from the driving chip 6, the first 24-bit data is extracted by the first LED element 5 and then transmitted to the data latch inside the LED element 5, the remaining data is shaped and amplified by the internal shaping processing circuit and then forwarded to the next cascaded LED element 5 through the control data signal output pin DO, and the signal is reduced by 24 bits each time the LED element 5 is transmitted. The LED elements 5 adopt an automatic shaping forwarding technology, so that the cascade number of the LED elements 5 is not limited by signal transmission, and only the requirement of signal transmission speed is limited. After the auxiliary data signal input pin BIN receives the data signal to phagocytose 24bit data, the auxiliary data signal input pin BIN receives the data, if no signal exists on the control data signal input pin DIN, the auxiliary data signal input pin BIN receives the data, the auxiliary data signal input pin BIN is switched to receive the input signal, the fact that the cascade transmission of the signal cannot be affected due to the damage of the control chip of one of the LED elements 5 is guaranteed, the control chip is kept in the auxiliary data signal input pin BIN receiving state until next startup after power failure is confirmed again, and accordingly the breakpoint continuous transmission function is achieved. Illustratively, the LED element employed may be a six-pin chip of model WS 2813-Mini.
With reference to fig. 1 to 4, an impedance element may be disposed in series between the control data signal input pin BIN and the ground pin GND of each LED element 5, that is, an impedance element R is disposed in series between the patterned conductive structure 46 and the patterned conductive structure 45 in the second transparent conductive layer 4; capacitive reactance elements are connected in series between the control data signal input pin DIN of each LED element 5 and the second power signal input pin VDD of the corresponding LED element, for example, capacitive reactance elements are connected in series between the control data signal input pin DIN of a certain LED element 5 and the second power signal input pin VDD of the LED element 5 immediately above the certain LED element 5. I.e. capacitive reactance elements C are arranged in series between the patterned conductive structures 44 and the patterned conductive structures 42 in the second transparent conductive layer 4. For example, the impedance element includes two pins, and the two pins of the impedance element may be correspondingly adhered to the patterned conductive structures R1 and R2 in the second transparent conductive layer 4, respectively, so as to satisfy that the impedance element is connected in series between the control data signal input pin BIN and the ground pin GND of the LED element 5. The capacitive reactance element comprises two pins, and the two pins of the capacitive reactance element can be correspondingly adhered to the patterned conductive structures C1 and C2 in the second transparent conductive layer 4 respectively so as to satisfy the requirement that the capacitive reactance element is connected in series between the control data signal input pin DIN of the LED element 5 and the second power signal input pin VDD of the corresponding LED element.
With reference to fig. 1 to 4, the LED element 5 may include a control chip and a single-color LED chip, the driving chip 6 located in the non-display area NAA of the transparent LED display panel provides a control signal to the control chip in the LED element 5, and the control signal controls the LED chip according to the received control signal to control the light emitting brightness and the light emitting time of the LED element 5. When the LED elements 5 include monochromatic LED chips, the light emission colors of all the LED elements 5 are the same, and the corresponding transparent LED display panels are monochromatic transparent LED display panels; when the LED elements 5 include three-color LED chips, each LED element 5 includes three colors of red, green, and blue LED light emitting devices, the emission color of each LED element 5 can be changed by adjusting the emission luminance of each color of LED light emitting device, and the corresponding transparent LED display panel can perform full-color display.
For example, the material forming the first transparent conductive layer 2 may include one of nano silver, indium tin oxide, or carbon nanotubes, the material forming the second transparent conductive layer 4 includes one of nano silver, indium tin oxide, or carbon nanotubes, the material forming the insulating layer 3 includes one of epoxy resin or polypropylene, and the materials forming the first transparent conductive layer 2, the insulating layer 3, and the second transparent conductive layer 4 are all transparent materials, so that compared with the prior art in which the PCB light bar is used to provide the LED element 5, the transmittance of the transparent LED display panel is greatly improved, and further, the transparency of the transparent LED display panel is improved.
With reference to fig. 1 to 4, the transparent LED display panel may further include a transparent encapsulation structure 7, where the transparent encapsulation structure 7 is disposed on a side of the LED element 5 away from the transparent substrate 1. The transparent substrate 1 can be a glass substrate, the transparent packaging structure 7 is a glass cover plate, and the glass cover plate and the glass substrate form a sandwich structure through adhesive; the transparent substrate 1 can also be a flexible substrate, the transparent packaging structure 7 can be a flexible cover plate, and the flexible cover plate is adhered to the flexible substrate through adhesive. By adopting the transparent packaging structure 7, the transparency of the transparent LED display panel can not be influenced, and the damage to the LED element 5 caused by the penetration of water vapor and oxygen in the control to the LED element 5 can be effectively avoided.
For example, as shown in fig. 3, the distance d between any two LED elements 5 arranged in a lattice may be set to be 10mm, and the LED elements 5 used may be six-legged lamp beads with the specification of 3.5mm by 3.5 mm. Since the LED elements 5 are opaque, in order to ensure the transparency of the transparent LED display panel, the size of the LED elements 5 is set smaller than the distance between adjacent LED elements 5.
For example, with reference to fig. 1 and fig. 2, the sequence of the manufacturing process of the transparent LED display panel is as follows:
