A light-emitting device is provided. The light-emitting device includes a substrate including a plurality of pixels, each pixel including a plurality of subpixels designed to emit light with different colors. The plurality of subpixels includes a first subpixel designed to emit red light, a second subpixel designed to emit green light, and a third subpixel designed to emit blue light. The first subpixel includes a first light source formed on the substrate, a red light-emitting layer covering the first light source, and a first yellow color filter covering the red light-emitting layer. The second subpixel includes a second light source formed on the substrate, a green light-emitting layer covering the second light source, and a second yellow color filter covering the green light-emitting layer. The third subpixel includes a third light source formed on the substrate. A method for fabricating the light-emitting device is also provided.

Light-emitting device with yellow color filters

A light filter structure is provided. The light filter structure includes a first filter layer disposed over the substrate. The first filter layer has a transmittance greater than 50% in a first waveband, wherein the first filter layer is an interference-type filter. The light filter structure further includes a second filter layer disposed over the substrate. The second filter layer has a transmittance greater than 50% in a second waveband, wherein the second filter layer is an absorption-type filter. The first waveband partially overlaps the second waveband at the wavelength in a third waveband, and the third waveband is in an IR region. Furthermore, an image sensor used as a time-of-flight image sensor is also provided.

Light filter structure and image sensor

An optical sensor includes a sensing layer, a first shading filter, a second shading filter, and an alignment mark. The sensing layer includes an active area, a shading area, and a peripheral area. The sensing layer includes sensing units located in the active area. The first shading filter is disposed on the shading area. The second shading filter is disposed on the first shading filter. The alignment mark is disposed on the peripheral area. When a light beam is emitted to the shading area, the second shading filter is configured to block a first component of the light beam, and the first shading filter is configured to block a second component of the light beam.

Optical sensor and manufacturing method thereof

An image-sensing apparatus is provided. The image-sensing apparatus includes: an optical filter array including a two-band passing filter and an infrared filter; an RGB pixel array placed below the two-band passing filter; and a TOF pixel array adjacent to the RGB pixel array and placed below the two-band passing filter and the infrared filter, wherein a combination of the two-band passing filter and the infrared passing filter permits only the incident light in the infrared region to pass to the ToF pixel array.
