Problems solved by technology

In the traditional technology, the fingerprint recognition is placed as a separate module in the non-display area, such as the front lower frame, side or back. The fingerprint recognition of the above schemes is assembled as a separate module. This fingerprint recognition setting requires Occupies part of the space of the mobile phone module, which is not conducive to the trend of thinner and lighter electronic products
[0003] In order to increase the screen-to-body ratio of the display panel, a technical solution for fingerprint unlocking under the screen has been developed, but the fingerprint unlocking under the screen in the prior art generally uses an organic light-emitting display panel (OLED), but the cost of the organic light-emitting display panel is relatively high, which is not conducive to widely used

Abstract

The invention discloses a display panel, a display device, a touch position and a fingerprint identification detection method. The display panel comprises a plurality of scanning lines extending in the first direction and arranged in the second direction, a plurality of data lines extending in the second direction and arranged in the first direction, a plurality of sub-pixels and a plurality of touch lines, and the scanning lines and the data lines intersect to define areas of the sub-pixels. Fingerprint recognition units is arranged at the overlapping positions of the scanning lines and the touch lines, each fingerprint recognition unit comprises a control end, an input end and an output end, the control end is electrically connected with the scanning line, and the input end and / or the output end are / is electrically connected with the touch line; each touch line comprises a first end and a second end, a first voltage is input into the first end, and a second voltage is input into thesecond end. The fingerprint recognition unit is integrated in the display panel, a fingerprint recognition module does not need to be independently manufactured, and lightening and thinning of an electronic product are facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a display device, a touch position, and a fingerprint identification detection method. Background technique [0002] With the development of display technology, mobile phones are indispensable in daily life as an important communication tool. The pursuit of maximizing the display area and integrating fingerprint recognition in the panel display area have become the mainstream development direction of display technology. In the traditional technology, the fingerprint recognition is placed as a separate module in the non-display area, such as the front lower frame, side or back. The fingerprint recognition of the above schemes is assembled as a separate module. This fingerprint recognition setting requires Occupying part of the space of the mobile phone module is not conducive to the trend of thinner and lighter electronic products. [0003] In o...
