Embodiment 1

[0038] Such as figure 1 As shown, in this embodiment, the display panel 10 of the present invention includes a substrate 601, a light emitting layer 120, a barrier layer 200, a first insulating layer 301, a second insulating layer 302, a flat layer 303, a thin film transistor unit 170, and a conductive unit 127 The pixel definition layer 304 and the cathode layer 407 .

[0039] The substrate 601 is a flexible substrate or a rigid substrate, which is used for receiving other film layers of the display panel 10 and also plays a protective role.

[0040] The barrier layer 200 is disposed on one side of the substrate 601. Since the barrier layer 200 is usually used to prepare various electrical components and is sensitive to external water vapor impurities, the barrier layer 200 can isolate external water vapor impurities and improve the service life of the electrical components.

[0041] The TFT unit 170 includes an active layer, a gate layer, a source layer and a drain layer. ...

Abstract

The invention discloses a display panel and a preparation method thereof. The display panel includes a display area; a plurality of light emitting units are evenly arranged in the display area; and at least one organic photodetection unit is arranged in the display area. edge or corner of the display area. The beneficial effect of the present invention is that: the display panel and the preparation method thereof of the present invention realize ultraviolet detection without affecting the screen ratio of the display panel by arranging an organic photoelectric detection unit at the edge of the light-emitting layer. The OLED unit at the edge is replaced with an active layer. The active layer uses a mixed material capable of sensing ultraviolet rays. The mixed material used in the active layer is the material of the electron transport layer and the hole transport layer, which reduces the preparation cost.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] It is well known that ultraviolet rays have an important impact on human skin. According to reports, only 10% of human skin comes from physiological aging, and 90% of the real damage to the skin and "aging" are ultraviolet rays in the sun. When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate pigment synthesis, destroy the skin's moisturizing function, make the skin dry, damage the elastic fibers in the dermis, and cause fine lines. Under strong exposure, it can also cause skin inflammation and burns. When there are abnormalities, it will become pigmented skin cancer, etc. On the other hand, proper sun exposure can promote the body's absorption of vitamin D. Therefore, it is particularly important for personal health to measure the...
