Embodiment Construction
[0023] First of all, it is to be noted that, unless the context clearly dictates otherwise, as used herein and in the appended claims, the singular includes the plural and vice versa. Thus, when referring to the singular, the plural of the corresponding term will generally be included. Similarly, the words "comprise" and "include" are to be interpreted as being inclusive and not exclusive. Likewise, the terms "include" and "or" should be construed as inclusive, unless such an interpretation is expressly prohibited herein. Where the term "example" is used herein, particularly when it follows a group of terms, said "example" is exemplary and illustrative only, and should not be considered to be exclusive or inclusive .
[0024] In addition, it should be noted that when introducing elements of the present application and embodiments thereof, the articles "a", "an", "the" and "said" are intended to mean that there are one or more elements; unless otherwise It is stated that "pl...

An OLED display panel and a method for fingerprint identification using the OLED display panel are disclosed. The OLED display panel includes: a transparent substrate; an OLED array substrate arranged opposite to the transparent substrate; and a fingerprint identification unit. The OLED array substrate includes: a plurality of scanning lines; a plurality of data lines; a plurality of OLED pixel units, each OLED pixel unit is connected to a corresponding data line and a scanning line; a plurality of light detection units, each light detection unit is connected to a The OLED pixel unit is located between the reset terminal and the data line, and is configured to detect light reflected by the transparent substrate to generate a light detection signal, and output the light detection signal via the data line under the control of the reset signal from the reset terminal. The fingerprint recognition unit is connected with the plurality of data lines and is configured to recognize the fingerprint pattern according to the light detection signals from the plurality of data lines.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting diode (Organic Light Emitting Diode, OLED for short) display panel and a fingerprint identification method using the OLED display panel. Background technique [0002] With the development of display technology, many display devices such as mobile phones and tablet computers have fingerprint identification functions. Current fingerprint recognition sensors may include three types. The first type is an optical sensor, which is relatively large. The second type is a capacitive sensor, which requires a higher accuracy of dpi (dots per inch, dots per inch). The third type is an ultrasonic sensor. Contents of the invention [0003] Embodiments of the present invention provide an OLED display panel and a fingerprint identification method using the OLED display panel, which can perform fingerprint identification while displaying without affecting t...
