Problems solved by technology

In capacitive fingerprint identification, the electrodes at both ends of the capacitor tend to generate parasitic capacitance with the internal components of the display panel in the electronic device, which makes the fingerprint detection signal and the display signal interfere with each other, thus affecting the quality of fingerprint identification

Abstract

The invention discloses a light sensation module and a display panel. The light sensing module comprises a substrate; a plurality of light sensing unit switch tubes located on the substrate; a first organic flat layer which is positioned on one side, far away from the substrate, of the light sensing unit switch tube; a plurality of light sensing units which are positioned on one side, far away from the light sensing unit switch tube, of the first organic flat layer; a common electrode which is located on the side, away from the first organic flat layer, of the light sensing unit; a first inorganic layer which is located between the first organic flat layer and the common electrode, and is provided with a first groove, wherein the first groove is located between every two adjacent light sensing units. According to the present invention, the risk of film stripping of the first organic flat layer can be reduced, and the performance reliability of the light sensing module is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a photosensitive module and a display panel. Background technique [0002] With the development of electronic science and technology, fingerprint recognition has been gradually applied to display devices such as mobile phones. The fingerprint recognition technology in electronic devices generally uses optical technology, silicon technology (capacitive and radio frequency) and ultrasonic technology. In capacitive fingerprint identification, the electrodes at both ends of the capacitor tend to generate parasitic capacitance with the internal components of the display panel in the electronic device, causing mutual interference between the fingerprint detection signal and the display signal, thus affecting the quality of fingerprint identification. In fingerprint recognition technology, the optical fingerprint recognition sensor realizes its detection and recognitio...
