A method for improving readability of a display inside a motorized object comprises applying a polarization means on a side window of a motorized object, wherein an ambient incident light ray comes through the side window and is reflected by a surface of a display inside the motorized object to form a reflected light ray, and substantially filtering out display incident light S-polarization and allowing display incident light P-polarization to pass through. The polarization means has a linear polarization reflecting or absorbing direction that is substantially parallel to the plane of the surface of the display. A display readability enhancing system comprises the polarization means. When ambient light passes through the window and shines onto the interior display, the dominant light polarization is p-polarization for the interior display with minimum surface reflectivity upon reflecting from the interior display, resulting in good display visibility under strong ambient light conditions.

An optical filter is configured to attenuate visible light and pass near-infrared light and an image sensor is configured to detect light reflected by a surface after the reflected light passes through the optical filter.

Processing circuitry is configured to receive the image data from the image sensor and determine near-infrared glare information based on the received image. The near-infrared glare information can be used to adjust display parameter associated with the surface or characterize near-infrared glare properties of the surface.

In some embodiments, a display system comprises a set of reflective or semi-reflective elements. A display emits light such that one portion of the light travels a first path through the display system, and another portion travels a second path, which includes a reflection from a windshield. The two portions form virtual images that are simultaneously viewable in a headbox. In some embodiments, the source of light that forms the image is an ambient source, and the display system is at least in part a sunlight-driven display system. In some embodiments, virtual images have a monocular depth that is far from a viewer. In some embodiments, the virtual images are closer to a viewer, and a gesture camera captures information about gestures made by a viewer, said gestures modifying the virtual images or some property or dynamics of the vehicle.

In the display panel, the light extraction layer and the encapsulation layer form an anti-reflection layer, so that light emitted by the emissive layer group is emitted as much as possible, and the brightness of the display panel is improved.
