An organic EL display panel has a multi-layered structure in which a first electrode and a second electrode are formed on a transparent panel and an organic EL layer is formed between the first and second electrodes. A method for sealing the organic EL display panel includes the steps of forming a buffer layer of an organic matter such as silicon oxide and silicon nitride on the transparent panel, and locating a shield cover on the buffer layer. Thus, adhesive strength between the panel and an adhesive is enhanced to prevent external humidity and oxygen from being permeated into the panel, thereby increasing life span of the display.

The present general inventive concept relates to a method of compensating tilt using a two-axis geomagnetic sensor and an acceleration sensor and an apparatus. Using the principle where a geomagnetic field value measured in a state where one axis of the two-axis geomagnetic sensor is set up vertically is identical to a Z-axis geomagnetic field value, the Z-axis geomagnetic field value can be evaluated by using two axes of the two-axis geomagnetic sensor. Accordingly, an azimuth angle can be easily calculated, so that the azimuth angle changed by tilt can be compensated. Therefore, there is an effect that a constant azimuth can be always output even though tilt occurs. In addition, when a module of the two-axis geomagnetic sensor and the acceleration sensor is used in a mobile equipment, the two-axis geomagnetic sensor can automatically measure geomagnetic field values of three axes by a simple motion where a user vertically sets up or rotates up and down the mobile equipment. Therefore, there is an effect that a constant azimuth angle can be always output by compensating the azimuth angle changed by tilt.

The present invention relates to an efficient snapshot technique based on a mapping for a large logical volume shared in multiple hosts. According to the present invention, problems of time delays in a conventional snapshot technique is solved by employing a FAB and an SSB, which are bits representing whether a COW operation is carried out to a mapping entry. In other words, the present invention solves the problems of delaying a write operation of corresponding volume, which is simultaneously executed when a snapshot is created, until the snapshot creation is completed. Further, in the write operation carried out after the snapshot creation, an operation of determining whether the COW operation is carried out is achieved by reading only an original mapping block by using the FAB and the SSB, without reading out the snapshot mapping block. Therefore, an additional disk access operation is decreased when carrying out a write operation to the volume in which the snapshot exists, thereby improving the performance of operation. Furthermore, in a snapshot destruction operation, the operation of determining whether the COW operation is carried out or not can be achieved without access to the snapshot mapping block, thereby preventing the degradation of performance. In case there is at least one snapshot, the determination operation can be achieved by an access to the original mapping block. Consequently, constant performance is always provided without the number of the snapshots.
