Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

Abstract: A Fan-Out package having a main die and a dummy die side-by-side is provided. A molding material is formed along sidewalls of the main die and the dummy die, and a redistribution layer having a plurality of vias and conductive lines is positioned over the main die and the dummy die, where the plurality of vias and the conductive lines are electrically connected to connectors of the main die.

Abstract: A device includes a semiconductor fin, and a gate stack on sidewalls and a top surface of the semiconductor fin. The gate stack includes a high-k dielectric layer, a work-function layer overlapping a bottom portion of the high-k dielectric layer, and a blocking layer overlapping a second bottom portion of the work-function layer. A low-resistance metal layer overlaps and contacts the work-function layer and the blocking layer. The low-resistance metal layer has a resistivity value lower than second resistivity values of both of the work-function layer and the blocking layer. A gate spacer contacts a sidewall of the gate stack.

Abstract: A line scribing method of a line scriber includes the steps of providing an electronic map; planning a line scribing path on the electronic map; converting the planned line scribing path into a plurality of planned geographical coordinates; transmitting the planned geographical coordinates to a line scriber; positioning a location to be scribed by the line scriber via a satellite connection to generate a positioning coordinate; comparing the positioning coordinate with an starting geographical coordinate of the planned geographical coordinates, and correcting the planned geographical coordinates according to the difference between the positioning coordinate and the starting geographical coordinate if the positioning coordinate is unequal to the starting coordinate, or moving the line scriber according to the planned geographical coordinates sequentially to perform a line scribing operation if the positioning coordinate is equal to the starting coordinate, so that the line scriber can perform a line scribing o
