The invention discloses a display panel and a preparation method thereof. The display panel comprises a fingerprint identification area and a touch area surrounding the fingerprint identification area. The display panel further comprises a base layer, a packaging layer, a first conducting layer and a second conducting layer, in the fingerprint recognition area, transparent conducting units in onedirection are connected through second connecting wires to form a first electrode, and transparent conducting units in the other direction are bridged through first connecting wires to form a second electrode. The technical effect of the invention is that the integrated integration of fingerprint identification and touch control functions is realized.
Description
technical field [0001] The invention relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] In the case of full-screen mobile phones have been widely popularized, in-screen fingerprint recognition technology has become a key technology in the field of consumer electronics due to its convenient identity authentication operations. The current in-screen fingerprint recognition technology is mainly based on optical under-screen fingerprint recognition. This technology uses the light-emitting pixels of the OLED display as the light source, and uses the micro-lens of the fingerprint module to read the reflected light of the fingerprint of the finger and convert it into an electrical signal to read the fingerprint image. However, the externally attached fingerprint recognition module requires hollowing out of structural materials such as buffer foam and heat dissipation copper sheet under the screen, which occu...
