Embodiment Construction

[0061] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] First of all, it should be noted that the display device refers to a deformable and bendable display device made of soft materials.

[0063] see Figure 1 to Figure 3 , as a specific embodiment of the display device of the present invention, it includes a substrate layer 110 , a TFT layer 120 , an anode layer 130 , an OLED layer 140 , a cathode layer 150 , an encapsulation layer 160 and a protective film 170 .

[0064] It should be noted that the substrate layer 110 refers to the BL (Buffer layer) layer prepared on the surface of the PI layer 300 after the PI (Polyimide) layer 300 is prepared on the surface of the substrate 200 by a spin-coating process during the preparation of the display device.

[0065]Further, the TFT layer 120 refers to a TFT (Thin...

Abstract

The invention discloses a display device, which comprises a substrate layer, a TFT layer, an anode layer, an OLED layer, a cathode layer, a packaging layer and a protective film, wherein the TFT layer is formed on the substrate layer; the anode layer is formed on the TFT layer; the OLED layer is formed on the anode layer; the cathode layer is formed on the OLED layer and the substrate layer which is not covered by the OLED layer; the packaging layer is formed on the cathode layer and the substrate layer which is not covered by the cathode layer; the packaging layer, the cathode layer and the substrate layer form a coating space; the protective film is formed on at least one of the following positions: the surface, departing from the TFT layer, of the substrate layer, the part between the TFT layer and the anode layer, the part between the anode layer and the OLED layer, the part between the OLED layer and the cathode layer, the part between the cathode layer and the packaging layer, and the surface, departing from the cathode layer, of the packaging layer; and the protective film is suitable for deforming along with bending of the display device. By the display device, the problem that the overall display effect of a screen body of a traditional display device is uneven is effectively solved. The invention further discloses a preparation method of the display device and electronic equipment.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a display device, a preparation method, and electronic equipment. Background technique [0002] At present, AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode) as a new type of packaging structure, has high chromaticity, high contrast, wide viewing angle, high brightness, self-illumination, fast response, It can realize flexible display and other characteristics, and has been widely used in electronic devices such as mobile phones and media players. [0003] Among them, the display device implemented by AMOLED has the advantages of being able to maintain the unfolded state for easy operation when working, keep the curled state for easy carrying when storing, and can also be hung on the body to present a wearable state, making it widely concerned. However, when the traditional display device is applied to the occasion of flexible displ...
