Abstract: A light source module and a display device are provided. The light source module includes a light source, a light guide plate, and an optical film set including multiple first optical microstructures having a first surface, multiple second optical microstructures having a second surface, and multiple third optical microstructures having a third surface. Each of the multiple first optical microstructures has a first vertex angle, each of the multiple second optical microstructures has a second vertex angle, and each of the multiple third optical microstructures has a third vertex angle. The third vertex angle is less than the first vertex angle, and the first vertex angle is less than or equal to the second vertex angle. By configuring the aforementioned optical microstructures, the light source module of the disclosure may greatly improve the collimation of light and has favorable luminance.

Abstract: An interconnect structure comprises a first dielectric layer, a first metal layer, a second dielectric layer, a metal via, and a second metal layer. The first dielectric layer is over a substrate. The first metal layer is over the first dielectric layer. The first metal layer comprises a first portion and a second portion spaced apart from the first portion. The second dielectric layer is over the first metal layer. The metal via has an upper portion in the second dielectric layer, a middle portion between the first and second portions of the first metal layer, and a lower portion in the first dielectric layer. The second metal layer is over the metal via. From a top view the second metal layer comprises a metal line having longitudinal sides respectively set back from opposite sides of the first portion of the first metal layer.

Abstract: An optical module includes a micro spectrometer. The micro spectrometer includes an optical crystal, a lens, and a photosensitive assembly. The optical crystal is configured to receive detection light and covert the detection light into interference light. The optical crystal is surrounded by a sleeve, the sleeve configured to fix a position of the optical crystal. The lens is configured for receiving the interference light and focusing the interference light. The photosensitive assembly is configured for imaging the interference light into an interference image. The optical module further comprises a controller. The controller is electrically connected to the photosensitive assembly, and the controller is used to convert the interference image into light wavelength signals and light intensity signals.

Abstract: A portable system includes a portable device and a power adapter to supply power to the portable device. The portable device includes a rechargeable battery and a measurement chip to measure charge remaining in the rechargeable battery. The power adapter includes a transmission line, a microprocessor, and a display unit. The microprocessor receives the readout of the amount of charge remaining in the rechargeable battery from the measurement chip via the transmission line, and generates a display signal according to the charge remaining. The display unit displays the charging progress of the rechargeable battery according to the display signal received from the microprocessor.
