Detailed Description
A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
The invention is an improvement on the basis of patent document 'an LED transparent display screen without edge wiring and a production method thereof' (the publication number is CN113506520A, and is called as a basic patent in the following).
The contents of the basic patent are as follows:
both the front and back surfaces of the transparent substrate 20 are provided with conductive layers. The front surface of the transparent base material 20 is provided with an R pin pad 31, a G pin pad 32, a B pin pad 33, and a C pin pad 34. The LED lamp bead 1 has 4 pins which are respectively an R pin, a G pin, a B pin and a C pin and are sequentially and respectively welded on an R pin bonding pad 31, a G pin bonding pad 32, a B pin bonding pad 33 and a C pin bonding pad 34; the LED lamp beads 1 are arranged on the transparent base material 20 in a 45-degree rotating mode, namely, a connecting line of central points of any two adjacent pin pads forms a non-zero included angle with the Y direction, and the included angle is preferably 45 degrees; the R lead 41, the G lead 42, the B lead 43 and the C lead extend along the Y direction, and the R lead 41, the G lead 42 and the B lead 43 are not overlapped with each other in a mode of 'rotating for 45 degrees' arrangement of the LED lamp beads 1, so that the phenomenon that a large wiring area is occupied to avoid lead overlapping does not occur; when the angle is 45 °, the leads connecting the R pin pad 31, the G pin pad 32, and the B pin pad 33 have an equal pitch therebetween. Wherein the Y direction is the vertical direction in fig. 1-5, 7-9 and the X direction is the horizontal direction in fig. 1-5, 7-9. The transparent substrate 20 used in the present invention is a transparent double-sided board, and its structure is shown in fig. 6. A through hole is drilled in the transparent substrate 20, and a layer of copper is plated on the wall of the through hole by a copper deposition process to obtain a conductive through hole 35, so as to connect the first conductive layer 21 and the second conductive layer 22. The conductive via 35 needs to be within the connected pad 36 or the independent pad 37 and needs to be kept at a certain distance D from the outer edge of the connected pad 36 or the independent pad 37. In fig. 9, R, G, B, C denotes the positions of the R pin pad 31, the G pin pad 32, the B pin pad 33, and the C pin pad 34 on the front surface of the transparent base material 20, respectively, and C1 denotes the positions where the connection lines 44 are connected to the conductive vias 35.
In the basic patent, the LED is placed in a rotating manner, the R lead 41, the G lead 42, the B lead 43 and the C lead are arranged on the back side, the connecting wire 44 is arranged on the front side, the R lead 41 is connected with the R lead through the pin pad and the conductive through hole 35, the G lead 42 is connected with the G lead, the B lead 43 is connected with the B lead, the C lead is connected with the connecting wire 44, and the R lead 41, the G lead 42, the B lead 43 and the C lead all extend to the edge of the display area 60 along the Y direction; because one edge of the screen in the Y direction has no wiring, the seamless splicing of the two screens can be realized in the Y direction by the screen, and the splicing quantity of the screens in the X direction is not limited.
According to the invention, by changing the wiring mode of the basic patent, on the premise of meeting the safety spacing of the yellow light process, the upper limit of the splicing number of the Y-direction screens can be increased, and further the line resolution of the spliced LED transparent display screen is increased. Specifically, this can be achieved in two ways:
(1) any one group of leads in the expansion screen is arranged between the two groups of leads in the initial screen;
(2) any set of leads in the expanded screen is staggered from the set of leads in the original screen.
In the LED transparent display screen, R lead wire 41, G lead wire 42, B lead wire 43 of a row of LED lamp pearl 1 are shared, and the C lead wire of a line of LED lamp pearl 1 is shared, generally can distribute the lead-out position of C lead wire near each row of LED lamp pearl 1 evenly, so a row of LED lamp pearl 1 corresponds a set of lead wire, and this a set of lead wire has included R lead wire 41, G lead wire 42, B lead wire 43 and C lead wire, and a LED transparent display screen has the multiunit lead wire.
In the invention, the LED transparent display screen positioned on the edge is an initial screen, and the LED transparent display screen positioned on the inner side of the initial screen Y is an extended screen.
Example one
As shown in fig. 1, the original screen is marked as F, the expanded screen is marked as EX, in fig. 1, the numeral numbers added after F distinguish different original screens, and the numeral numbers added after EX distinguish different expanded screens. The extended screen is at the end far from the flexible circuit board 50, the initial screen is at the end near the flexible circuit board 50, the extended screen and the initial screen are in the same substrate circuit board, and the lead of the extended screen extends to the flexible circuit board 50 through the circuit gap from the initial screen.
A group of R lead wires 41, a group of G lead wires 42, a group of B lead wires 43 and a group of C lead wires of the expansion screen are respectively marked as EXR, EXG, EXB and EXC in sequence, and a group of R lead wires 41, a group of G lead wires 42, a group of B lead wires 43 and a group of C lead wires of the initial screen are respectively marked as FR, FG, FB and FC in sequence; all of the leads of the above-described indicia are independent of each other and are not connected and will eventually extend to different PINs on the flexible circuit board 50.
As shown in fig. 3, EXR extends between and is spaced from FR and FG, EXG extends between FG and FB, EXB extends outside FB, and EXC extends between FR and FC.
Of course, the relative positions of the R, G, B, and C leads 41, 42, 43, and C leads are changed according to the bonding positions of the LED leads, and therefore, the arrangement order of the EXR, EXG, EXB, and EXC, FR, FG, FB, and FC along the X direction is also changed.
Example two
As shown in fig. 4, the only difference from the first embodiment is that: any set of leads in the expanded screen is disposed between the two sets of leads of the original screen.
In the first and second embodiments, a minimum distance should be maintained between adjacent leads, where the minimum distance is a safety distance that satisfies the yellow light process capability, and it is sufficient to ensure that no short circuit occurs and that the LED can be manufactured. The leads of all the expansion screens can be led out only by occupying the space of the initial screen, so that the number of the expansion screens corresponding to one initial screen is limited by the minimum distance.
As shown in fig. 2, in the basic patent, only two original screens can be spliced in the Y direction. In the invention, the expansion screen can be arranged between the two initial screens, and if one initial screen can correspond to N expansion screens, 2N expansion screens can be arranged between the two initial screens. As shown in FIG. 1, two expansion screens EX1-1 and EX2-1 exist between the initial screen F1-1 and the F2-1, wherein each group of leads of EX1-1 is connected to the flexible circuit board 50 through F1-1, and each group of leads of EX2-1 is connected to the flexible circuit board 50 through F2-1; because the X-direction edges of the initial screen and the extended screen are free of wiring, the splicing of the X-direction screens is not limited. In fig. 1, the case when N is 1 is listed, and in fact, if the column spacing is large enough, 2 or more expansion screens can be introduced, so as to break through the resolution limit of the spliced transparent screen
In the first and second embodiments, after the leads extend to the flexible circuit board 50, the leads are connected to two independent display driving modules through the flexible circuit board 50 by wiring, and are driven by different sets of ICs respectively.
By adopting the scheme of the invention, because the line of the expanded screen needs to occupy the space of the initial screen, the line spacing needs to be increased to accommodate the line of the expanded screen, in this situation, the line spacing and the line spacing of the pixel points are possibly inconsistent, but according to the prior experience, the displayed image is not influenced due to the inconsistent line spacing and line spacing.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not to be construed as limiting the claims.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
