Abstract: A bottom-emission light-emitting diode (LED) display includes a transparent substrate, a plurality of LEDs bonded on the substrate, a packaging layer formed on the substrate to cover the LEDs, and a reflecting layer formed on the packaging layer to reflect light emitted by the plurality of LEDs. The reflecting layer has a non-smooth shape or the packaging layer has different refractivities.

Abstract: A gate structure includes a substrate divided into an N-type transistor region and a P-type transistor region. An interlayer dielectric covers the substrate. A first trench is embedded in the interlayer dielectric within the N-type transistor region. A first gate electrode having a bullet-shaped profile is disposed in the first trench. A gate dielectric contacts the first trench. An N-type work function layer is disposed between the gate dielectric layer and the first gate electrode. A second trench is embedded in the interlayer dielectric within the P-type transistor region. A second gate electrode having a first mushroom-shaped profile is disposed in the second trench. The gate dielectric layer contacts the second trench. The N-type work function layer is disposed between the gate dielectric layer and the second gate electrode. A first P-type work function layer is disposed between the gate dielectric layer and the N-type work function layer.

Abstract: A testing device includes a power supply and a plurality of testing ports. The testing ports are electrically connected to the power supply. Each of the testing ports includes a contact and a current clamper. The contact is configured to electrically couple a device under test (DUT). The current clamper is connected between the power supply and the contact and configured to allow a limited current having a predetermined current value to flow to the contact.

Abstract: The present invention is directed to an interactive image device and interactive method thereof for a traditional photo frame or a fameless painting, the device comprises a frame body provided with a fastening position, a display surface for display an image, an effect unit for generate effects, a trigger unit and a circuit module to enable or disable the effect unit in responding the operation of the trigger unit by a user. The user is able to get different interactive effect feedbacks by inserting the trigger unit to the fastening position each time, thus the present invention can easily integrate the displayed image with interactive effects and interact with users by novel operating methods.
