Problems solved by technology

This will make the two ends of the conductive bridge 520 unable to be arranged on the connection point 511 of the electrode 510, as Figure 5 shown
Once the misalignment of the conductive bridge 520 occurs during the manufacturing process, the touch function in this area will fail

Abstract

The invention discloses a touch display panel and a preparation method, which are used for increasing the connection area of connection points so as to improve the connection success rate of touch channels in the manufacturing process. The touch display panel comprises an organic light-emitting layer and a touch electrode layer. The touch electrode layer is arranged on the organic light-emitting layer. The touch electrode layer further comprises a carrier plate, a conductive span bridge and two electrodes. The two electrodes are arranged on two opposite side edges of the carrier plate, an isolation gap is formed between the two electrodes, each electrode is provided with at least one conduction piece and a connecting point, the conduction pieces are arranged outside the connecting points,and the conductive span bridge is bridged between the two electrodes and is connected with the two conduction pieces.

Description

technical field [0001] A structure and a preparation method of a touch display panel, in particular to a touch display panel and a preparation method. Background technique [0002] With the rapid development of display technology, the cathode ray tube screen in the past has evolved to the current liquid-crystal display (LCD). In addition to the greatly improved viewing range and resolution of the current liquid crystal display, the overall size of the display is also reduced. Moreover, the display screen is not only available for viewing, but also has a touch function, so as to provide users with an experience of viewing and operating at the same time. [0003] In the manufacturing process of the traditional touch display, the construction of the conductive bridge will be carried out. The purpose of constructing the conductive bridge is to provide conduction of the electrodes 510 in the touch layer. However, since liquid crystal packaging is a high-precision operation, th...
