Abstract

The invention provides a display panel and a display apparatus. The display panel comprises a substrate, a thin film transistor layer, a positive electrode layer, an organic light emitting layer, a negative electrode layer, a thin film packaging layer and a particle layer. According to the display panel, the particle layer is arranged between the thin film transistor layer and the thin film packaging layer; the particle layer consists of multiple silver nanoparticles; equivalently, photon state density and exciton spontaneous radiation efficiency are improved according to an SPR effect on surfaces of the nanoparticles, so as to improve the luminous efficiency of an AMOLED display panel; and in addition, by virtue of a light reflection effect of the silver nanoparticle layer, loss of lightrays can be reduced, and the light extracting efficiency of the AMOLED is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel display device. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) display has many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and has gradually become the successor. The third generation display technology after liquid crystal display. Compared with LCD (Liquid crystal displays, liquid crystal display), OLED has the advantages of saving power, being thinner, and having a wider viewing angle, which is incomparable to LCD. At present, people have higher and higher requirements for the fineness of the display, that is, the resolution, but the production of high-quality, high-resolution OLED displays still faces many challenges. [0003] According to the driving method, OLED display devices can be divided into two...
