A kind of flexible display panel, its preparation method and wearable device

Abstract

The invention relates to the display field, in particular to a flexible display panel, a preparation method thereof and a wearable device. A flexible display panel, including a flexible substrate, a thin film transistor array, an organic light-emitting unit, and an encapsulation layer arranged in sequence, and a thermally conductive composite layer is provided on the side of the flexible substrate away from the thin film transistor array; the thermally conductive composite layer includes silicon A ketone rubber matrix and a gallium-indium alloy filled in the silicone rubber matrix; in the gallium-indium alloy, the mass ratio of gallium to indium is 3-5:1. The heat-conducting composite layer composed of silicone rubber and gallium-indium alloy can quickly conduct heat and reduce heat accumulation. Moreover, the thermally conductive composite layer of the present invention has high yield strength, excellent strength-to-weight ratio, high elasticity, corrosion resistance, and wear resistance. It is used for flexible display panels or wearable devices, which not only reduces the risk of heat accumulation and burns to users , Also prolong the service life of the product.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display panel, a preparation method thereof and a wearable device. Background technique [0002] Wearable electronics are portable devices that are worn directly on the body, or integrated into the user's clothing or accessories. With the high integration, miniaturization and multi-function of wearable electronic products, the heat generation density also increases. For every 2°C increase in temperature of components in wearable electronic products, their reliability will drop by 10%; the service life of components in a 50°C environment is only one-sixth of that in a 25°C environment [0003] Wearable electronic products are worn by users for a long time. If the temperature of the product is slightly higher than the body temperature during operation, the human body can be used as a heat dissipation mechanism to make the product work stably; however, if the internal components of t...

Problems solved by technology

[0003] Wearable electronic products are worn by users for a long time. If the temperature of the product is slightly higher than the body temperature during operation, the human body can be used as a heat dissipation mechanism to make the product work stably; however, if the internal components of the wearable electronic product generate The heat is too concentrated to dissipate heat quickly, and the working temperature is higher than the body temperature for a long time, which is very likely to cause the danger of low temperature burns to the user
