Disclosed herein are various embodiments related to luminescence-based reflective display pixels. In one embodiment, among others, a luminescent-based pixel includes a luminescent layer including luminophores distributed in a matrix. The luminescent layer is configured to receive light from an ambient environment through a first side of the luminescent layer and has an index of refraction that is higher than an index of refraction of the ambient environment. The luminescent-based pixel includes a mirror disposed on a second side of the luminescent layer that is opposite the first side of the luminescent layer. The luminescent-based pixel also includes a diffusive surface to randomize the direction of incident light.

Lesions caused by insects feeding on plants are associated with the generation of regions of blue-green fluorescence in such as the cotton boll carpel wall and in the lint region. The present disclosure now provides methods and devices to rapidly and non-invasively detect and measure the insect-related fluorescence and relate the fluorescence generated to the likelihood of insect damage in a crop. In particular, the methods are related to stink bug damage in the cotton plant, but are also suitable for the detection of insect-related damage of any plant. The methods of detecting insect-induced damage in a target plant tissue may comprise exposing a target plant or a fragment thereof, to an ultraviolet or violet light; and detecting an ultraviolet light-induced fluorescence from the target plant or the fragment thereof, thereby indicating the presence of insect-related plant damage. Further provided are devices configured for the identification of insect-induced damage in a plant or a fragment thereof, comprising: a source of an ultraviolet or violet light, at least one light detector; an electronic system for converting an output electrical signal to a measurement of the intensity of fluorescent light detected by the detector; and an output system to convert the measurement of the intensity of the fluorescent light to an indicator for indicating that a target plant or fragment thereof has insect-induced damage.

An image projection apparatus includes a projector, a frame, and a partially transparent screen. The frame retains the screen under tension, such that the screen is inclined at an angle with respect to a plane of emission of light from the projector. The screen has a front surface arranged such that light emitted from the projector is reflected therefrom. The projector projects an image such that light forming the image impinges upon the screen such that a virtual image is created from light reflected from the screen, the virtual image appearing to be located behind the screen.

A display apparatus and a method for manufacturing an optical compound layer are provided. The display apparatus comprises a light source and an optical compound layer, wherein the light source is adapted to emit a light beam, and the light beam has a polarization direction. The optical compound layer is disposed on the light source correspondingly to receive the light beam. The optical compound layer comprises a thin film and a plurality of dopants doped therein. One of the thin film and the dopants has a specific orientation which is substantially the same as the polarization direction of the light beam and the refractive indexes of the thin film and the dopants are substantially the same as well.

Disclosed herein are a light source module and an electronic device using the same. The light source module is disposed in a housing component of the electronic device and includes a light source and a light guide element having a light-entering surface, a light-departing curved surface and a light-reflecting curved surface. The light-entering surface receives the light from the light source. The normal line directions of the light-departing curved surface are approximately perpendicular to the normal line direction of the light-entering surface. The light is reflected by the light-reflecting curved surface and then leaves the light guide element in the normal line directions of the light-departing curved surface.
