摘要： A backlight unit for a vehicular component is disclosed. In particular, the vehicle component is for displaying vehicular information. The backlight unit comprises a screen divided into an array of segments and a transparent plate for directing light rays through the screen. Each segment of the array of segments is capable to operate between a mode for permitting light rays to pass through, allowing light rays passing through the transparent plate and the screen, and a mode for blocking light rays from passing through blocking light rays from passing through the screen.

摘要： A method of manufacturing a segmented electro-optic display includes providing an electro-optic display stack including a first substrate layer, a first layer of light-transmissive electrically-conductive material, a layer of electro-optic material, a lamination adhesive, a second layer of light-transmissive electrically-conductive material, and a second substrate layer. The method also includes forming electrically-isolated conductive segments on the second layer of electrically-conductive material using a laser etching process that includes irradiating the second substrate and second electrically-conductive layers at multiple locations with a laser emitting light within a first range of wavelengths. The second substrate layer is transmissive of light within the first range of wavelengths, and the light-transmissive electrically-conductive material is substantially absorptive of light within the first range of wavelengths. At each of the multiple locations, the second substrate layer substantially transmits the light emitted from the laser and the light-transmissive electrically-conductive material substantially absorbs the light and is removed.

摘要： A display device, a display panel, and an array substrate are provided. The array substrate includes an active layer and a light-blocking and heat-insulating layer. The light-blocking and heat-insulating layer is arranged on a side of the active layer and configured to block light and insulate heat for the active layer. The light-blocking and heat-insulating layer includes light-absorbing materials and light-reflecting materials. One of the light-absorbing materials and the light-reflecting materials form a light-blocking body. The other one of the light-absorbing materials and the light-reflecting materials are dispersed in the light-blocking body.

摘要： A display panel includes a light source section, a light guide section, a liquid crystal layer, a partition section, a display section, and a diffraction section. The light source section emits plural lights of different colors. The light emitted from the light source section enters the light guide section. The light that has passed through the light guide section enters the liquid crystal layer. The partition section partitions the liquid crystal layer into plural pixel regions. The partition section includes plural scanning lines and plural black matrices arranged at intervals in an intersecting direction that intersects with a thickness direction of the light guide section. An image formed by the light emitted from the plural pixel regions is displayed on the display section. The diffraction section diffracts the plural lights that have entered the light guide section from the light source section.
