Abstract: A support structure, a manufacturing method thereof and a display device are provided. The support structure includes a metal substrate, and a buffer layer provided on the metal substrate; the support structure includes a bending region and a non-bending region; a portion of the metal substrate located in the bending region has a recess so that a thickness of the portion of the metal substrate located in the bending region is smaller than a thickness of a portion of the metal substrate located in the non-bending region; and the buffer layer is provided on a side of the metal substrate having the recess, and is at least located in the recess.

Abstract: Provided are a backboard support structure, a preparation method therefor, and a display device. The display device includes a display substrate and a backboard support structure; the backboard support structure includes a substrate support film and an adhesive layer arranged in a laminated manner. The backboard support structure is bonded to the non-display side of the display substrate via the adhesive layer, and includes a first bendable region and a first non-bent region. The adhesive layer includes a first portion located in the first bendable region and a second portion located in the first non-bent region; the first portion has a modulus of elasticity of about 1 Kpa-150 Kpa, the second portion has a modulus of elasticity of about 150 Kpa-250 Kpa, and the substrate support film has a modulus of elasticity of about 1 Gpa-10 Gpa.

Abstract: The present disclosure provides a flexible display device. The flexible display device has different base materials for the back supporting film at the bonding region and the non-bonding region, so that it can satisfy the requirements for AOI and bending resistance respectively. The present disclosure also provides a back film for a flexible display device and a preparation method thereof.

Abstract: Cycloalkyl acid derivatives, a preparation method thereof, and a pharmaceutical application thereof are described. In particular, a cycloalkyl acid derivative represented by general formula (I) and a medical salt thereof, a preparation method thereof, and an application of the cycloalkyl acid derivative and the medical salt thereof as URAT1 inhibitors, and particularly as therapeutic agents for diseases related to an abnormal uric acid level are described, wherein definitions of substituent groups in general formula (I) are the same as the definitions in the specification.
