Abstract: A method for testing a liquid crystal panel is provided. The method simulates an outside force endured by the liquid crystal panel when the liquid crystal panel is assembled as a finished product, so that unqualified liquid crystal panels can be detected before the finished product is put into use.

Abstract: An adjusting apparatus is provided for a projector and received in a case of the projector. The case includes a front wall defining a through hole. Two protrusions each defining a notch are formed on the inside surface of the front wall. The adjusting apparatus includes two supporting members partially received in the case and movably coupled to the case, and an operating member partially exposed out of the through hole of the front wall of the case. A connecting member is connected to the operating member, and received in the notches. Each supporting member forms a plurality of teeth thereon. The connecting member forms a plurality of teeth at two ends thereof respectively for mating with the teeth of the supporting member. The operating member is rotated for driving the connecting member to move up and down relative to the supporting member.

Abstract: A flat panel display device includes a display, a connector secured to a bottom of the display, and a stand. The connector includes a pivot portion and two opposing arm portions extending from the pivot portion. The stand includes a top wall with a receiving space defined thereunder. The top wall defines a mounting channel therein. The mounting channel includes a receiving groove for pivotably receiving the pivot portion of the connector, and two opposing passing grooves extending from the receiving groove to allow the corresponding arm portions to pass therethrough and enter into the receiving space. The flat panel display device with simple structure is easy for use, assembly and disassembly.
