Abstract: An epitaxial wafer structure of light-emitting diode includes, from bottom to up, a substrate, an N-type GaN layer, a MQW light-emitting layer and a P-type GaN layer, in which, at least one InyGa1?yN/AlN composition layer (0<y?1) is inserted in the N-type GaN and at least one multi-layer AlN/InzGa1?zN composition layer (0<z?1) is inserted in the P-type GaN layer; and AlN part in the inserting layer increases barrier to form a blocking layer and the InyGa1?yN layer reduces barrier to form a carrier capture layer so as to generate two-dimensional electron gas of higher concentration and more-concentrated distribution in the N-type GaN layer and the P-type GaN layer, thereby improving current spreading capacity.

Abstract: A method of fabricating a light-emitting diode includes: proving a substrate; forming an N-type layer, a low-temperature AlxInyGa1?x?yN (0?x?1, 0?y?1, x and y cannot both be zero at the same time) layer, a multiple quantum-well active region, an AlzGa1?zN (0?z?1) electron blocking layer, an AlxInyGa1?x?yN (0?x?1, 0?y?1) separation layer and a P-type layer over the substrate in successive; before growth of the multiple quantum-well active region, growing a low-temperature AlxInyGa1?x?yN layer to form a “V”-shaped indentation or pit; after growth of the multiple quantum-well active region, growing a thin AlzGa1?zN electron blocking layer and then a separation layer under two-dimensional growth mode to form holes between the active region and the P-type layer to separate throughout dislocation within the V pit coverage range and contact with the P-type layer, thus eliminating current leakage and improving inverse current leakage capacity and anti-static capacity of the epitaxial wafer.

Abstract: A support stand includes a bracket and a base connected with the bracket. The bracket includes a main body, a movable member, and a resilient member. The main body defines a receiving slot therein, and the movable member is partially received in the receiving slot, with opposite ends of the resilient member resisting the main body and the movable member. The base includes a latching member sleeved on the main body of the bracket. The latching member includes a latching portion for impelling and guiding the movable member to be received in the receiving slot of the main body, and the movable member to contact the resilient member. After the movable member passes over the latching portion, an elastic force created by the resilient member extends the movable member from the receiving slot of the main body, and the movable member is latched in the base.

Abstract: A support stand for a flat-panel display monitor includes a hinge assembly and a support structure having a top end partially receiving the hinge assembly. The hinge assembly includes a first latching module. The first latching module includes an elastic member and a movable plate connected to the elastic member. The support structure includes a second latching module detachably connected to the first latching module. The second latching module includes a positioning plate having a latching portion extending from a bottom surface thereof. The latching portion is capable of latching with the movable plate. When the movable plate is pressed, the elastic member is deformed so that the second latching module is detached from the first latching module.
