Transparent film screen display panels usually use single-sided transparent film circuit boards, which have limited current carrying capacity, and the brightness of small-pitch transparent film screens is low and the quality is unstable; the wiring and display panel are separately stacked to realize a borderless display panel. Similarly, because the welding points need to be misaligned with LED devices, the stack welding points are limited, and small-pitch transparent film screens cannot be realized; a display screen and a method for preparing a display screen similar to patent number CN202110052996.0, an oxidized metal material layer is formed on the bonding area of ​​the display panel, and an anisotropic conductive adhesive film is formed on the oxidized metal material layer, and the conductive pins in the gold finger area of ​​the flexible circuit board penetrate the anisotropic conductive adhesive film and the oxidized metal material layer and are bonded to the bonding pins in the bonding area. In this way, by using an oxidized metal material layer to strengthen the protection of the bonding area of ​​the display panel, even if there is a gap between the gold finger area of ​​the flexible circuit board and the display panel, the oxidized metal material layer composed of multiple dense film layers can be used for water and oxygen isolation protection, which can reduce the problem of black spots on the bonding pins or poor pin routing or even downtime, thereby improving the display problem of the display screen caused by water and oxygen intrusion;

[0093] The working principle and beneficial effects of this embodiment are as follows: by arranging a battery in the hole pressing roller 6 to store battery energy for the rotary driver 37, the winding of the wire during the processing process is prevented from affecting the production; the rotary driver 37 drives the fixed driving frame 38 to rotate, thereby driving the thread undercutting table 39, the thread middle cutting table 40 and the thread upper cutting table 41 to rotate synchronously to provide the cutting power; by rotating the thread undercutting table 39 on the fixed driving frame 38, the extension and retraction of the thread undercutting table 39 is adjusted, and after reaching the specified position, the thread undercutting table 39 is further rotated by setting the stop thread, so that the thread middle cutting table 40 can be retracted and retracted to the upper limit in the thread undercutting table 39. While the thread middle cutting table 40 is connected to the thread undercutting table 39 through threaded cooperation, the thread middle cutting table 40 also slides longitudinally in the thread undercutting table 39 through the limit slider, thereby facilitating the limit control during the rotation and retraction process, which is beneficial to the retraction; the connection of the thread upper cutting table 41 and the thread middle cutting table 40 is similar; thereby facilitating the retraction adjustment and using different cutting blade tables for use;

[0094] At the same time, the circular cutting blades in the thread bottom cutting stage 39, the thread middle cutting stage 40 and the thread upper cutting stage 41 are used in combination, that is, the thread upper cutting stage 41 independently cuts the lamp position slot with a smaller diameter, the thread middle cutting stage 40 and the thread upper cutting stage 41 are combined to cut the lamp position slot with an intermediate diameter, and the thread bottom cutting stage 39, the thread middle cutting stage 40 and the thread upper cutting stage 41 are combined to cut the lamp position slot with a larger diameter;

[0095] Circular cutting blades of different diameters correspond to the preparation of different lamp slots, thereby adapting to the requirements of different lamp slot 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 ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
