Abstract: A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

Abstract: The present invention discloses a back contact solar cell. The back contact solar cell includes a semiconductor substrate having a front surface and a rear surface; a first conductive type semiconductor region having a first conductive type and a second conductive type semiconductor region having a second conductive type at an interval on the rear surface of the semiconductor substrate. Furthermore, the rear surface of the semiconductor substrate has a texturing structure at the interval between the first conductive type semiconductor region and the second conductive type semiconductor region.

Abstract: Provided are a bedding and a bedding cover therefor, the bedding including an upper cover having a first fastening member; a lower cover having a second fastening member; and a bedding insert fitted between the upper cover and the lower cover, and having a third fastening member for coupling to the upper cover and a fourth fastening member for coupling to the lower cover, the upper cover and the lower cover being coupled to each other by the first fastening member and the second fastening member, and being separated from each other by releasing the coupling between the first fastening member and the second fastening member; the upper cover further including a fifth fastening member disposed at a position corresponding to the third fastening member; and the lower cover further including a sixth fastening member disposed at a position corresponding to the fourth fastening member.

Abstract: Provided is a test method of a NAND flash memory. The method includes programming a page of a selected memory block in the flash memory; accumulating a program result of the page; and repeating the programming of other pages and the accumulating of the program result of the other pages until all pages in the selected memory block are programmed.

Abstract: A method for testing a multi-chip package formed of different types of semiconductor devices, using an integrated burn-in test program which can reduce throughput time, reduce the possibility of error by an operator, and reduce workload. A multi-chip package is tested in burn-in equipment capable of applying a plurality of scan control clock signals. An integrated burn-in test program requires fewer burn-in test programs to be uploaded, fewer contact tests, and fewer bin sorting operations.
