Abstract

The invention provides a rollable display device and a preparation method of a heat-conducting glue layer. The rollable display device comprises a scroll and a flexible display panel arranged on the outer side of the scroll, and the flexible display panel comprises a display device, a supporting piece and the heat-conducting glue layer located between the display device and the supporting piece which are arranged in a stacked mode. The supporting piece is located on the side, close to a reel, of the display device, and the heat conduction coefficient of the heat conduction glue layer ranges from 1 watt / m. DEG C to 5 watt / m. DEG C. The problem of brightness difference caused by non-uniform heating of the display device for a long time is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a rollable display device and a method for preparing a thermally conductive adhesive layer. Background technique [0002] Organic Light Emitting Diode (OLED) is an active light-emitting display device, which has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, wide color gamut, light and thin, and can be shaped. With the continuous development of display technology, OLED technology is increasingly used in flexible displays and transparent displays. Transparent display is an important branch of display technology. It refers to image display in a transparent state. The viewer can not only see the image in the display device, but also see the scene behind the display device, which can realize virtual reality / augmented reality ( Virtual Reality / Augmented Reality, VR / AR) and 3D display functions. [0003] As an important application tec...
