Abstract: A height measurement system includes: a first fixed assembly, configured to connect to an external fixing part so that the height measurement system is fixed on the external fixing part for use; a head plate, configured to move downwards from the first fixed assembly to the head of a user; a second fixed assembly, disposed on the head plate and being movable along with the heat plate; a digital tape measure, comprising a mounting assembly and a tape disposed in the mounting assembly, one of the mounting assembly and the tape head being attached to the first fixing assembly and the other to the second fixing assembly; a memory storing a standard height value of the first fixed assembly; and a data acquisition unit, configured to acquire a first tensile length of the tape when the head plate moves from the first fixed assembly to the user's head.

Abstract: A display panel and a method for manufacturing the display panel are provided. The display panel includes a planar region and a bending region. The display panel includes a flexible substrate and a driving circuit layer. The flexible substrate at least includes a first flexible layer, a barrier layer and a second flexible layer. The driving circuit layer is disposed at a side of the second flexible layer away from the barrier layer. In the bending region, a groove is disposed at a side of the first flexible layer away from the barrier layer. The technical problem of stress concentration in the bending region is alleviated by disposing the groove.

Abstract: A display device is provided. The display device includes a first base layer, a second base layer, a thin film transistor layer, an organic light-emitting layer, a display region, and a light-transmissive sub-region. At the same time, a through hole and a light-guiding lens structure are disposed, and the through hole is filled with a light-guiding medium. After light passes through the light-guiding medium and the light-guiding lens structure, light transmittance is high, and brightness of each region is kept uniform, thereby improving imaging quality and imaging function of the display device.
