Touch panel and manufacturing method thereof as well as display device

Abstract

The invention discloses a touch panel and a manufacturing method thereof as well as a display device, and belongs to the field of touch control. The control panel comprises a plurality of first signal lines and a plurality of second signal lines that cross one another to define a plurality of sub-pixel areas including a pixel opening area; a transistor and a photosensitive element are disposed in each sub-pixel area, wherein the gate of the transistor is connected to one of the plurality of first signal lines, and one of the source and the drain is connected to one of the plurality of second data lines, while the other one is connected to the first pole of the photosensitive element in the respective sub-pixel area, wherein the photosensitive element is disposed in a sub-pixel area except for the disposal area of the transistor and the pixel opening area. The touch panel also comprises a transparent electrode layer. The second pole of each photosensitive element is connected to the transparent electrode layer. In addition, each photosensitive element is configured to generate a light intensity sensing signal between the first pole and the second pole thereof based on the detected light intensity. According to the invention, full-screen fingerprint acquisition of a display device may be achieved.

Description

technical field [0001] The present invention relates to the field of touch control, in particular to a touch panel, a manufacturing method thereof, and a display device. Background technique [0002] Electroluminescence device is a kind of self-luminous display device, which has attracted wide attention due to its advantages such as wide viewing angle, high contrast ratio and high response speed. With the development of the field of electroluminescence, organic electroluminescent devices (such as organic light emitting diodes, Organic Light Emitting Diode, OLED) can achieve more excellent brightness, driving voltage, response rate and Therefore, it has become the mainstream of the current display market. At present, OLED display devices can realize touch sensing by applying capacitive touch technologies such as in-cell, on-cell and out-cell, but it is still difficult Fingerprint collection is realized by capacitive touch. In this regard, although some optical fingerprint ...

At present, OLED display devices can realize touch sensing by applying capacitive touch technologies such as in-cell, on-cell and out-cell, but it is still difficult Acquisition of fingerprints by capacitive touch

In this regard, although some optical fingerprint sensors and radio frequency fingerprint sensors can realize fingerprint collection in a small area outside the display area, because they will reduce the display light transmittance, it is difficult to set them in the full screen range, so full-screen fingerprint collection cannot be realized
