Problems solved by technology
However, as the area of the fingerprint unlocking area expands, it will inevitably increase the window area of the heat dissipation film on the back of the OLED panel and expose a large area of U-film (protective film), and the surface impedance of U-film itself is so large that it is almost non-conductive. Generally, the induced charge accumulation generated on the surface will react against the Panel and affect the TFT characteristics of the display panel. Therefore, the fingerprint hole Mura phenomenon will appear in the fingerprint hole area, that is, the brightness of the fingerprint hole area and the rest of the Panel is uneven, and the fingerprint hole area is dark. Therefore, there is an urgent need to solve the problem of fingerprint hole Mura in the above fingerprint hole area

The invention relates to the technical field of display, and discloses a conductive adhesive structure and a display device. The conductive adhesive structure comprises: a first adhesive layer, a conductive layer and a second adhesive layer arranged in sequence, wherein the first adhesive layer is provided with a plurality of The conductive particle filling area is distributed at intervals, the conductive particle filling area is provided with conductive particles, and the conductive particles are electrically connected with the conductive layer. In the conductive adhesive structure, when used on the back of the display panel, the induced charges generated on the back of the display panel can be dispersed evenly in the entire back of the display panel, without causing the accumulation of the induced charges and alleviating the darkening of the fingerprint unlocking area. To solve the problem, ensure that the display brightness of the unlocked area and other display areas is uniform and consistent, so that the overall brightness of the display panel can be displayed uniformly.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a conductive adhesive structure and a display device. Background technique [0002] At present, in order to meet the ever-changing needs of consumers for a sense of technology, more and more new technologies are gradually applied to the display modules of mobile phones, among which the large fingerprint unlocking area and even the half-screen and full-screen fingerprint unlocking area are the key links. However, with the expansion of the fingerprint unlocking area, it is bound to increase the window area of the heat dissipation film on the back of the OLED panel and expose a large area of U-film (protective film), and the surface impedance of the U-film itself is so large that it is almost non-conductive. Induction charge accumulation on its surface will react on the Panel and affect the TFT characteristics of the display panel. Therefore, the fingerprint hole Mura p...
