Problems solved by technology

[0004] In the prior art, the fingerprint identification module is usually integrated on the TFT (Thin Film Transistor, thin film transistor) substrate of the display panel, that is, the fingerprint identification module is introduced on the basis of the existing TFT, which will make the fingerprint identification module correspond to The penetration rate of the area is greatly reduced, and the light received by the fingerprint recognition module is relatively weak, which leads to inaccurate fingerprint recognition

Embodiment Construction

[0029] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. A display region and an non-display region are arranged. The display region includes the main display area and an auxiliary display area. The display panel is further provided with at least one fingerprint identification unit. The forward projection of the fingerprint identification unit onthe plane where the display panel is located is in the auxiliary display area. The main display area is provided with a plurality of first pixel regions arranged in the array form, each first pixel region is provided with a first color resistance layer, the auxiliary display area is provided with a plurality of second pixel regions arranged in the array form, each second pixel region is providedwith a second color resistance layer, and the penetration rate of first color resistance layers is less than that of the second color resistance layers. Since the penetration rate of the auxiliary display area is larger than that of the main display area, the increase of the brightness of the auxiliary display area thus is facilitated, the influence of the introduction of the fingerprint identification unit on the penetration rate of the auxiliary display area is reduced, the brightness difference between the main display area and the auxiliary display area is reduced, and thus the overall display effect of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] Human fingerprints are unique and non-deformable, which makes fingerprint recognition more secure. At the same time, because of its simple operation, it is widely used in various fields, for example, the field of display technology. In the field of display technology, taking a mobile phone as an example, when unlocking or opening a specific application, it can be done through fingerprint recognition. [0003] With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform au...
