Publication number: 20240126001Abstract: A switchable backlight module is disclosed. The switchable backlight module includes two light source modules arranged parallelly with respect to a plane. Each of the light source modules includes a turning film and a LGP. The LGP is of an edge-lit type arranged parallelly under the turning film. A light ray enters the LGP from a light incident side of the LGP, exits the LGP from a light emergent surface of the LGP, enters the turning film, and exits the turning film from a surface of the turning film away from the LGP. The light incident side of the LGP of one of the light source modules is perpendicular to the light incident side of the LGP of the other light source module. The switchable backlight module is in an anti-peeping mode having a narrow viewing angle when only an upper one of the light source modules emits light.Type: ApplicationFiled: July 19, 2023Publication date: April 18, 2024Inventors: YU-HUAN CHIU, CHIEN-WEI LIAO, YEN-LUNG CHEN

Patent number: 11942364Abstract: In some embodiments, the present disclosure relates to a method of forming an interconnect. The method includes forming an etch stop layer (ESL) over a lower conductive structure and forming one or more dielectric layers over the ESL. A first patterning process is performed on the one or more dielectric layers to form interconnect opening and a second patterning process is performed on the one or more dielectric layers to increase a depth of the interconnect opening and expose an upper surface of the ESL. A protective layer is selectively formed on sidewalls of the one or more dielectric layers forming the interconnect opening.
