Abstract
The invention provides a display panel and a display device, and all display modules can be controlled at the same time through a common substrate. The photosensitive device layer is arranged on the common substrate, the distance between the photosensitive module and the light-emitting pixels can be increased under the condition that the original thickness of the display panel is not increased, and therefore at least two light shielding layers can be arranged between the light-emitting pixels and the photosensitive module, and the collimation effect of the optical collimation structure on light rays can be effectively improved; and the fingerprint identification effect is further improved. Besides, because the photosensitive module layer is installed on the common substrate, the fingerprint identification result obtained by one photosensitive module can be shared to all the display modules, so that all the display modules can synchronously respond to the fingerprint identification result, and the response speed of the fingerprint identification function on the large-size display panel is improved.
Description
technical field [0001] The present application belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background technique [0002] With the continuous development of terminal technology, the application of electronic equipment is becoming more and more extensive. Due to the uniqueness of skin patterns, such as fingerprint patterns or palm patterns, in order to protect the user's information security, the use of fingerprint recognition functions on electronic devices is becoming more and more common, such as for mobile phone unlocking, mobile payment (such as payment, transfer), etc. . In the related art, the fingerprint identification function is realized by an optical fingerprint identification unit. When the optical fingerprint identification unit is working, it is necessary to first collimate the light through an optical collimation structure, so as to improve the fingerprint identification effect. However, for a...
