  • Publication number: 20240427193
    Abstract: A backlight module includes a reflective plate, a plurality of light-emitting elements and a plurality of light guide plates. The reflective plate has light source grooves and first position limiting parts, and each light source groove has a reflective surface, a light outlet and a bottom side. The reflective surface is located between the light outlet and the bottom side. The first position limiting parts are respectively connected to the reflective surfaces and are respectively close to the light outlets. The light-emitting elements are respectively disposed in the light source grooves and respectively surrounded by the reflective surfaces. The light guide plates are respectively disposed in the light source grooves and respectively located between the reflective surfaces and the light-emitting elements. The first position limiting parts are respectively adapted to block the light guide plates from being separated from the reflective plate from the light outlets.

  • Publication number: 20240355628
    Abstract: A wafer processing method including following steps is provided. A release layer is formed on a first wafer. An adhesive layer is formed on a second wafer. One of the first wafer and the second wafer is a device wafer. The device wafer includes a valid die region and a trimming region. A handler is applied to place the first wafer on the second wafer, so that the release layer and the adhesive layer are bonded to each other, and the adhesive layer completely covers the valid die region. During the process of placing the first wafer on the second wafer, the handler directly moves the first wafer.
