Abstract

The embodiment of the invention provides a display panel and a preparation method thereof and a display device, relates to the technology of flexible display, and can effectively improve the color cast problem of the bent area of the display panel relative to the middle area and enhance the display effect. The display panel comprises a flexible substrate which comprises a middle area and a presetbending area arranged at least one side of the periphery of the middle area, wherein the preset bending area is set to be bent to the display direction back to the display panel; a display layer whichis arranged on the middle area and the preset bending area; and a transparent cover film layer which is arranged on the display layer and comprises a first part arranged on the middle area and a second part arranged on the preset bending area, wherein the first part and the second part are connected and the thickness of at least partial area of the second part gradually decreases along the direction away from the first part. The preparation method is used for preparation of the display panel.

Description

technical field [0001] The present invention relates to flexible display technology, in particular to a display panel, a preparation method thereof, and a display device. Background technique [0002] After the LCD (Liquid Crystal Display, liquid crystal display) panel is combined with the thin film transistor driving technology, its response speed, display brightness, contrast ratio and lightness of the display have been improved to a certain extent, and it has become a relatively mainstream display at present. However, since the liquid crystal molecules themselves do not emit light, the LCD panel must be displayed with the light from the backlight source, thus limiting the further development of LCD technology. [0003] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) panel has many advantages such as full solid state, active light emission, fast response speed, high contrast ratio and flexible display. As a new type of display, it has a wider development ...
