Problems solved by technology

Where the second conductive layer crosses the first conductive layer, a bridging method is adopted. However, due to the small area of ​​the bridging connection, the contact resistance at this place is relatively large, and the power consumption increases.

Abstract

An organic light-emitting diode touch panel comprises an organic light-emitting diode structure, a first conductive layer, a second conductive layer, a sense conductive layer, a third conductive layer and multiple second sense electrodes. The second conductive layer comprises multiple first sense electrodes. The sense conductive layer is positioned above the sense conductive layer and is in contact with the multiple first sense electrodes. The third conductive layer comprises multiple second drive electrodes. The first conductive layer is electrically connected to the third conductive layer.

Description

【Technical field】 [0001] The invention relates to the technical field of capacitive sensing, in particular to a mutual capacitive organic light emitting diode touch panel and a forming method thereof. 【Background technique】 [0002] Organic Light-Emitting Diode (OLED) touch panels are gradually and widely used in mobile terminals due to their flexibility, bright colors and high touch accuracy. Touch technology is divided into on-cell and in-cell technologies. The on-cell technology is to directly manufacture the touch electrodes on the thin film encapsulation layer of the OLED. However, the on-cell technology that directly manufactures capacitive sensing components on the OLED panel will be affected by the cathode of the OLED, which will cause interference to the driving signal and make the change in sensing capacitance before and after touch is small, making it difficult to monitor the touch chip. On the other hand, the current capacitive sensing components include a plur...
