Abstract

The invention discloses a display device and electronic equipment. The display device comprises a substrate; a light emitting unit on the substrate; an encapsulation layer covering the light emitting unit; and a light control piece located in the packaging layer, wherein the light control piece comprises a first material layer and a second material layer, a first interface is formed between the first material layer and the packaging layer, and a second interface is formed between the second material layer and the first material layer; the refractive index of the packaging layer is n1, the refractive index of the first material layer is n2, the refractive index of the second material layer is n3, and a relational expression that n1 > n2 > n3 is satisfied; light emitted by the light emitting unit comprises first light and second light, and the first light is directly emitted after penetrating through the packaging layer; and at least part of the second light is transmitted towards the light control piece, is totally reflected on the first interface and then is emitted from the packaging layer, and at least part of the second light penetrates through the first interface, reaches the second interface, is totally reflected on the second interface and then is emitted from the packaging layer. And the light extraction efficiency of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and an electronic device. Background technique [0002] Organic electroluminescence (Organic Light-Emitting Diode, hereinafter referred to as OLED) devices, which have the advantages of active light emission, good temperature characteristics, low power consumption, fast response, flexibility, ultra-thin and low cost, and are considered in the field of display technology It has a huge application prospect and has gradually become the next-generation mainstream display device after liquid crystal display and plasma display. [0003] However, the existing OLED display device still has the problem of poor light extraction efficiency. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a display device and an electronic device. [0005] One aspect of the present application provides a display device comprising: a substr...
