Abstract

The embodiment of the invention discloses an OLED panel and a fingerprint identification method thereof. The OLED panel comprises a TFT and a fingerprint identification and display area prepared abovethe TFT. The fingerprint identification and display area can sense fingerprints, and at least one photoelectric detector used for recognizing the fingerprints is arranged in the TFT. According to theembodiment of the invention, the photoelectric detector is moved into the TFT from the fingerprint identification and display area, so that the screen resolution of the OLED panel is improved, and the service life of the OLED panel is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED panel and a fingerprint identification method thereof. Background technique [0002] In recent years, more and more functions have been given to smartphones, such as the fingerprint recognition function for digital payment technology. Many traditional smartphones specially set up a non-display area to place the fingerprint recognition area. With the introduction and development of the full-screen concept, the display area occupies an increasing proportion of the mobile phone screen, and how to deal with the fingerprint recognition area becomes more and more critical. [0003] In the prior art, the fingerprint identification function can be integrated into the display panel of the mobile phone. One pixel in the display panel contains 4 sub-pixels, three of which are OLED (Organic Light-Emitting Diode, organic light-emitting diode) RGB light-emitting units, and one is an o...
