However, since the metal electrode leads of the film sensor in the touch screen are drawn from the frame to the binding end of the flexible circuit board (FPC), and the metal electrode leads need to occupy a certain width, it is difficult to achieve an ultra-narrow frame of the touch screen.
At present, the methods to achieve narrow borders in the industry mainly include: 1. Using non-metallic electrode leads, except for binding the FPC side, the other three sides can be made ultra-narrow, but the resistance value of the non-metallic electrode line will increase significantly with the length of the line increase, so this method is only suitable for small-sized touch screens; 2. Thinning the metal electrode lead makes the width of this part smaller in order to achieve a narrower frame, but due to the limitations of equipment, process and other factors, it is difficult to make the metal electrode lead finer

The invention relates to a touch display screen, a manufacturing method thereof, and an electronic device. The touch display screen includes a flexible surface layer, a touch sensing film and a display module stacked in sequence; the touch sensing film includes a touch part and a The lead part connected with the touch sensor film, the electrode lead on the touch sensor film is arranged on the lead part, the flexible surface layer covers the touch part of the touch sensor film and extends to cover the lead part of the touch sensor film, the touch sensor film touch partly covers the display surface of the display module, the lead part of the touch sensitive film and the part of the flexible surface layer covering the lead part are bent and attached to at least the side part of the display module. The present invention can realize narrow frame or even zero frame of the touch display screen, and effectively improve the screen ratio of the touch display screen. The flexible surface layer can effectively protect the induction lead part, especially the bending part, from being scratched or damaged by other external forces, so as to ensure that there will be no circuit breakage or other malfunctions.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to a touch display screen, a manufacturing method thereof, and electronic equipment. Background technique [0002] Nowadays, electronic devices are pursuing higher and higher screen-to-body ratios, and the borders of the display screens need to be narrower and narrower. However, since the metal electrode leads of the film sensor in the touch screen are drawn from the frame to the binding end of the flexible circuit board (FPC), and the metal electrode leads need to occupy a certain width, it is difficult to achieve an ultra-narrow touch screen frame. At present, the methods to achieve narrow borders in the industry mainly include: 1. Use non-metallic electrode leads. Except for the FPC side, the other three sides can be made ultra-narrow, but the resistance value of the non-metallic electrode line will increase significantly with the length of the line. increase, so this me...
