Describe herein are electronic devices that includes an enclosure having a flexible portion extending partially over the coverglass. In some instances, the flexible portion is configured to deform during assembly to allow the coverglass to be placed within the enclosure and to return to an original position once the assembly is complete. In other instances, the flexible portion may be configured to act as a bezel and to conceal any gap between an edge of the coverglass and a side wall of the enclosure from view.

A headlamp for vehicles having a light source, a lens unit and a liquid crystal shutter arranged between the light source and the lens unit. The liquid crystal shutter includes a multitude of surface areas that can each be controlled to switch the respective surface areas to a transparent or a non-transparent state so that a given light distribution pattern is generated. A polarizing reflector is assigned to the light source, so that a linearly polarized light beam is reflected in the direction of the liquid crystal shutter.

A display device, a reflective display panel and a reflective unit are provided. The reflective display panel includes an upper substrate unit, a lower substrate unit, a liquid crystal layer and a reflective unit. Wherein, the lower substrate unit is disposed oppositely to the upper substrate unit. The liquid crystal layer is disposed between the upper substrate unit and the lower substrate unit. The reflective unit is disposed at the outside of the lower substrate unit. After an external light passes through the upper substrate unit and the lower substrate unit, the external light is reflected by the reflective unit and generating a diffuse reflection effect. The present invention can save the mask fee, simplify the manufacturing process, avoid the defect and improve the reflection display effect.
