Description

Technical Field

[0001] The present invention relates to the field of display screen preparation, and more specifically, to a method for preparing a small-pitch transparent thin-film display screen. Background Art

[0002] The existing transparent thin-film screens for window displays mainly have the following implementation methods: The display panel and the driving and controlling board are stacked and welded. Since the stacked welding points need to be misaligned with the LED devices, the stacked welding points are limited, and a small-pitch transparent thin-film screen cannot be realized; The integrated wiring scheme of the display panel is adopted. For a small-pitch transparent thin-film screen with more lines, the lines are required to be thinner. Usually, the display panel of the transparent thin-film screen adopts a single-sided transparent thin-film circuit board, and the current-carrying capacity is limited. When making a small-pitch transparent thin-film screen, the brightness is low and the quality is unstable; The wiring and the display panel are separately stacked and welded to achieve a borderless display panel. Similarly, because the welding points need to be misaligned with the LED devices, the stacked welding points are limited, and a small-pitch transparent thin-film screen cannot be realized; Similar to a display screen and a method for preparing the display screen with the patent number CN202110052996.0, an oxide metal material layer is formed on the bonding area of the display panel, and an anisotropic conductive film is formed on the oxide metal material layer. The conductive pins in the gold finger area of the flexible circuit board penetrate through the anisotropic conductive film and the oxide metal material layer and are bonded to the bonding pins in the bonding area. In this way, by using the oxide metal material layer to strengthen the protection of the bonding area of the display panel, even when there is a gap between the gold finger area of the flexible circuit board and the display panel, since the bonding area is protected from water and oxygen by the oxide metal material layer composed of multiple dense film layers, the problems of black spots appearing on the bonding pins, poor pin wiring, or even downtime can be reduced, thereby improving the display defect problem caused by water and oxygen intrusion in the display screen;

[0003] However, this method for preparing the display screen cannot realize the preparation of a small-pitch transparent thin-film screen, cannot effectively improve the brightness, and cannot make the quality more stable. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the prior art. By adopting the method of separately stacking and welding the wiring and the display panel, but the stacked welding points are in the extended area of the display panel, the positions of the stacked welding points are more flexible and can achieve higher density.

Specific Embodiment Nine:

[0091] As Figure 4 — Figure 17 shown, a preparation method for a small - pitch transparent film display screen. The automatic grooving cutter includes a rotary driver 37, a fixed drive frame 38, a threaded bottom grooving table 39, a threaded middle grooving table 40, and a threaded upper grooving table 41. The rotary driver 37 is fixed in the jack support table 36. The transmission shaft of the rotary driver 37 drives the fixed drive frame 38 to rotate through a coupling. The threaded bottom grooving table 39 is connected to the fixed drive frame 38 through thread fitting. The inner wall of the threaded bottom grooving table 39 is connected to the threaded middle grooving table 40 through thread - limited connection. The inner wall of the threaded middle grooving table 40 is connected to the threaded upper grooving table 41 through thread - limited connection.

[0092] Circular cutting edges are fixed on the threaded bottom grooving table 39, the threaded middle grooving table 40, and the threaded upper grooving table 41.

[0093] The working principle and beneficial effects of this embodiment are as follows: A storage battery is arranged inside the hole-pressing extrusion roller 6 to store energy for the rotary driver 37 for use, preventing the winding of wires during processing and affecting production; the rotary driver 37 drives the fixed drive frame 38 to rotate, thereby driving the threaded bottom cutting table 39, the threaded middle cutting table 40, and the threaded upper cutting table 41 to rotate synchronously to provide the cutting-in power; by rotating the threaded bottom cutting table 39 on the fixed drive frame 38, the extension and retraction of the threaded bottom cutting table 39 are adjusted. At the same time, after reaching the specified position, through the setting of the anti-back-off thread, further rotating the threaded bottom cutting table 39 can make the threaded middle cutting table 40 extend and retract upwardly limited within the threaded bottom cutting table 39. While the threaded middle cutting table 40 is connected to the threaded bottom cutting table 39 through thread fit, the threaded middle cutting table 40 also longitudinally slides within the threaded bottom cutting table 39 through the limit slider, which is convenient for limit restraint during the rotation and retraction process and is beneficial for retraction; the connection between the threaded upper cutting table 41 and the threaded middle cutting table 40 is the same; thus, it is convenient to achieve telescopic adjustment and use different cutting edge tables for use;

[0094] At the same time, the circular cutting edges in the threaded bottom cutting table 39, the threaded middle cutting table 40, and the threaded upper cutting table 41 are used in combination. That is, the threaded upper cutting table 41 independently cuts the lamp position groove with a smaller diameter, the threaded middle cutting table 40 and the threaded upper cutting table 41 are combined to cut the lamp position groove with a medium diameter, and the threaded bottom cutting table 39, the threaded middle cutting table 40, and the threaded upper cutting table 41 are combined to cut the lamp position groove with a larger diameter;

[0095] The preparation of lamp position grooves with different diameters corresponds to different circular cutting edges, thereby adapting to the requirements of different lamp position groove apertures.

[0096] The above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also belong to the protection scope of the present invention.
