Abstract: Provided are a wavelength conversion apparatus, a light source system including the same, and a display device including the light source system. The wavelength conversion apparatus includes an angle deflection region and a wavelength conversion region for converting incident second light into excited light and then emitting same. The angle deflection region includes deflection units, each of which includes a light emergent face for emitting first light. A first included angle is formed between the light emergent face and a reference plane. First included angles between light emergent faces of at least two deflection units and the reference plane are not equal. The deflection units are located on a light path of the first light in a time sequence, so as to change an emergent angle of the first light in the time sequence, such that the first light is successively scanned at a preset position to form virtual pixels.

Abstract: The light source system includes a first light source, a light splitting device, a wavelength conversion device, and a light guiding device. The first light source emits first light. The wavelength conversion device includes at least a first color light region and a second color light region, which are sequentially inserted into an outgoing path of the first light. The first color light region emits second light excited by the first light to the light splitting device. The second color light region reflects the first light to the light splitting device. The light splitting device directs one of the first light and the second light to a light path and directs the other to the light guiding device. The first light or the second light is reflected by the light guiding device to the light splitting device, and then is guided to the light path by the light splitting device.

Abstract: The present disclosure relates to an image processing apparatus, a display apparatus, and an image processing and display apparatus and method. The image processing and display apparatus includes a data acquisition module, a data conversion and storage module, a data analysis module, a light-emitting module, and an image modulation module. The data conversion and storage module stores brightness data of a color of each pixel of an image as N-bit grayscale data based on data of a highest brightness of the color of the image and stores a brightness increase index of the color of the image. The light-emitting module adjusts emitted illumination light of the color based on the brightness increase index, so that the image modulation module modulates the illumination light of the color based on the N-bit grayscale data to modulate a displayed image.

Abstract: A display system includes: a light source, a light modulator, a recovery device, and a light intensity adjustment device. The light source emits original light that is incident to the light modulator. The light modulator modulates, on the basis of image data of an image to be displayed, the light incident thereto so as to form image light and non-image light. The recovery device recovers the non-image light, and the recovered non-image light is incident to the light modulator. The light intensity adjustment device adjusts, on the basis of the intensity of the non-image light corresponding to the currently modulated image to be displayed, the intensity of the original light emitted by the light source, thus allowing total intensity of the original light and the recovered non-image light that are incident to the light modulator to be kept consistent in modulation periods for different images to be displayed.

Abstract: An optical film and an optical imaging system are provided. The optical film includes a first lens layer, a first deflection layer, a reflection layer, a second deflection layer, and a second lens layer. The second lens layer is attached to a windshield. The reflection layer is configured to reflect an image light beam to form a first reflected light beam and the first lens layer and the first deflection layer are configured to amplify and/or deflect the first reflected light beam, to guide the first reflected light beam to a field-of-view direction. The second lens layer and the second deflection layer are configured to amplify and/or deflect a second reflected light beam, to guide the second reflected light beam to a first direction. The second reflected light beam is formed by that the windshield reflects the image light beam. The field-of-view direction is different from the first direction.
