Abstract

The invention discloses a support substrate, a preparation method thereof and a display panel, and relates to the technical field of the display. The support substrate comprises a device layer and a supporting layer which are stacked, the device layer comprises an identification area and a non-identification area, the supporting layer comprises a first supporting area corresponding to the identification area in position and a second supporting area corresponding to the non-identification area in position, and the thickness of the first supporting area is smaller than that of the second supporting area. According to the embodiment of the invention, through reducing the thickness of the first supporting area, corresponding to the identification area of the device layer, of the supporting layer, the transmittance of the first support area is improved, the optical loss is reduced, and the optical identification rate and sensitivity of an optical sensor are improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a support substrate, a preparation method thereof, and a display panel. Background technique [0002] Organic Light Emitting Display (OLED) has gradually become the first choice for screens. It has many advantages such as self-illumination, high luminous efficiency, short response time, high definition and contrast, and can also ensure that the screen has certain flexibility and reliability. adaptability. With the development of flexible display screens, people's expectations for foldable display products are getting higher and higher. [0003] At present, the flexible display panel usually includes a cover plate, a module functional film layer, a light-emitting film layer, a backplane film layer, a support layer and other film layer structures. Compared with other film structures in the entire flexible display panel, the supporting layer has a thicker thickne...
