Abstract: An electronic device including a first light emitting unit, a second light emitting unit, a first optical layer and a second optical layer is disclosed. The first light emitting unit emits a first light. The second light emitting unit emits a second light. At least one of the first light and the second light passes through the first optical layer. The second optical layer is overlapped with the first optical layer. The second optical layer is configured to scatter the first light emitted from the first light emitting unit. When the first light emitting unit emits the first light, the second light emitting unit selectively emits the second light.

Abstract: A structure and a method of forming are provided. The structure includes a first dielectric layer overlying a first substrate. A first connection pad is disposed in a top surface of the first dielectric layer and contacts a first redistribution line. A first dummy pad is disposed in the top surface of the first dielectric layer, the first dummy pad contacting the first redistribution line. A second dielectric layer overlies a second substrate. A second connection pad and a second dummy pad are disposed in the top surface of the second dielectric layer, the second connection pad bonded to the first connection pad, and the first dummy pad positioned in a manner that is offset from the second dummy pad so that the first dummy pad and the second dummy pad do not contact each other.

Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

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 display device including a first light emitting unit, a second light emitting unit, a first optical layer and a second optical layer is disclosed. The first optical layer is disposed on at least one of the first light emitting unit and the second light emitting unit, and the first optical layer includes a collimating layer. The second optical layer is disposed on the first light emitting unit. The second optical layer is configured to scatter a first light emitted from the first light emitting unit but does not scatter a second light emitted from the second light emitting unit.

Abstract: An input-voltage-off detection apparatus includes a voltage adjustment unit, a time delay unit, a voltage clamp unit, an auxiliary voltage discharge switch unit and an isolation notification unit. The voltage adjustment unit receives an input voltage. The time delay unit utilizes the input voltage to generate a direct current voltage. After the input voltage is cut off, the direct current voltage stored in the time delay unit discharges to the voltage adjustment unit. When the direct current voltage reduces to a predetermined voltage, the auxiliary voltage discharge switch unit is turned on, so that an auxiliary voltage winding sends a working voltage to the isolation notification unit. After the isolation notification unit receives the working voltage, the isolation notification unit notifies an electronic apparatus that the input voltage is cut off.

Abstract: The present invention is related to the apparatus for driving the light emitting devices with different colors. The input powers of the light emitting devices are measured and controlled by a feedback control system to maintain constant, and by setting different power inputs to the different light emitting devices different stable colors are produced.

Abstract: A figure exhibiting method is disclosed in this invention. The figure exhibiting method includes providing a figure and at least one light source. A number of color areas are included in the figure, inga first color area. The light source projects a variety of color lights onto the figure according to a program. The lights include a first light, which is the complementary color of the first color area in order to create a dark visual effect. Alternatively, a color light that is able to create a reflection of color from the first color area can be projected onto the figure, making the color of the area appear differently than it would under sunlight. A figure exhibiting device is also disclosed in this invention. The figure exhibiting device includes a light guiding plate, a transparent plate, a figure and at least one light source. The figure is clipped between the light guiding plate and the transparent plate. The figure includes a number of color areas, particularly, a first color area.
