Transparent display panel, preparation method of transparent display panel and display device

Abstract

The invention discloses a transparent display panel, a preparation method of the transparent display panel and a display device, and is used for prolonging the service life of an electroluminescent device in the transparent display panel. According to the transparent display panel provided by the embodiment of the invention, wherein the transparent display panel is divided into a display area arranged in an array and a light-transmitting area surrounding the display area; the display area comprises a transparent substrate, an electroluminescent device positioned on the transparent substrate, and a light blocking part located on one side, deviating from the electroluminescent device, of the transparent substrate; and the light blocking part is used for blocking light entering from one side,deviating from the electroluminescent device, of the transparent substrate to irradiate the electroluminescent device.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a transparent display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light emitting diodes (organic light emitting diodes, OLEDs) have become the most promising new display devices in recent years due to their advantages such as self-luminescence, fast response, ultra-light, ultra-thin, and high contrast. The transparent OLED display device is applied to the car sunroof. The car sunroof can not only have a display effect to display images and some external environmental indicators, but also have a certain degree of transparency to ensure that a certain amount of light enters the car, so that passengers can see the outside at any time environment, the combination of transparent display devices and vehicle sunroof makes the product more interesting and brings wonderful visual impact to the passengers. However, since th...

Problems solved by technology

However, since the vehicle sunroof is often exposed to sunlight during work, the ambient light directly irradiates the OLED device of the transparent display device, and the strong ultraviolet light will cause great damage to the OLED device, greatly reducing the service life of the OLED device, and the ambient light has a negative effect on the OLED device. The temperature of the car body rises due to the sunroof on the car, making the occupants feel uncomfortable

[0003] To sum up, the service life of the OLED device in the transparent display device used as a vehicle sunroof in the prior art is low, which in turn causes the service life of the transparent display device to be low
