Abstract

The embodiment of the invention provides a color film substrate and a manufacturing method thereof, a display panel and a manufacturing method thereof, and a display device. The color film substrate comprises a transparent substrate and a photoresist layer which are laminated; a first piezoelectric structure, arranged on one side, far away from the photoresist layer, of the transparent substrate and used for sending an ultrasonic signal according to the driving electric signal; a second piezoelectric structure, arranged on the side, away from the transparent substrate, of the photoresist layerand used for receiving a reflected ultrasonic signal formed after the ultrasonic signal is reflected and converting the reflected ultrasonic signal into a fingerprint recognition electric signal; a conductive support column, arranged on one side, far away from the photoresist layer, of the second piezoelectric structure, one end of the conductive support column being electrically connected with the second piezoelectric structure, and the other end of the conductive support column being electrically connected with a first electrode structure of a thin film transistor structure of the array substrate to transmit fingerprint identification electric signals. The first piezoelectric structure and the second piezoelectric structure which are used for fingerprint identification are arranged in the color film substrate, so that damage to wiring in the polarization process is avoided, and meanwhile, the production efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of display devices. Specifically, the present application relates to a color filter substrate and a manufacturing method, a display panel and a manufacturing method, and a display device. Background technique [0002] With the development of display technology and mobile communication technology, mobile electronic devices such as smart phones and tablet computers have become indispensable tools in people's lives, especially smart phones often store users' personal information. In order to improve the security of mobile electronic devices represented by smart phones, the existing mobile electronic devices mostly adopt the identity authentication method of fingerprint recognition, which not only protects the user's personal information but also facilitates the use of the user. [0003] The existing mobile electronic devices with fingerprint recognition function are mainly under-display fingerprint re...
